2010 Toyota Prius Brakes Problems

Your brake warning lights came on and your brake pedal became soft and unresponsive while driving, requiring much more pressure to stop and significantly increasing stopping distance. A Toyota dealership confirmed the brake booster and brake booster pump assembly failed (error code C1391), which is the same defect Toyota previously addressed in a Customer Support Program for 2010–2015 Prius models—but your vehicle's warranty period for this fix has expired despite normal mileage. The sudden loss of braking power created an unsafe driving situation that could have caused a collision. Fixing this will require replacing the brake booster and brake booster pump assembly.

Your 2010 Prius had its brake cylinder assembly and brake booster pump replaced in 2019 under a Toyota recall program due to a known braking system defect. As of February 2026, these replacement components are now failing again at 224,000 miles—sooner than the original faulty parts failed. Toyota has refused to provide any warranty coverage or assistance for this repeat failure.

Your brake pedal became very hard to push and your brakes didn't work effectively, meaning you needed more distance to stop—creating a collision risk. Multiple warning lights came on at once (brake system, ABS, check engine, battery, steering, tire pressure, and stability control). The brake booster pump, which helps your brakes work, had internal damage that allowed nitrogen gas to leak into the brake fluid, reducing braking power. This same part had already been replaced under a recall, but it failed again after only 41,000 more miles, suggesting the recall fix didn't work properly. Fixing this will likely require replacing the brake booster pump assembly with a new or properly designed unit.

Your Prius is displaying warning lights for ABS, traction control, and brakes, and you're experiencing a spongy, soft brake pedal with a hissing sound from the brake area. The car is throwing a code indicating an abnormal leak in the brake accumulator, which is severely affecting your ability to stop safely. Fixing this issue typically involves diagnosing and repairing the brake accumulator system, which may require replacement of brake system components.

While driving at 70 mph, your Prius suddenly jerked, failed to accelerate normally, and the steering wheel became stiff before the engine stalled. After reconnecting the battery to restart the vehicle, you noticed warning lights for the hybrid system and ABS, and your car would no longer go faster than 65 mph. The dealer suggested an ABS system failure may be responsible. This issue has occurred repeatedly over years without being fully diagnosed or repaired.

Your ABS light, brake light, and traction control light suddenly came on, your brake pedal became harder to push, and your car made weird humming noises every 5 seconds. Your brake actuator was found to be faulty, causing harsh braking and at least one near-miss where your brakes almost didn't stop in time. The repair involves replacing the faulty brake actuator, which is an expensive part.

Your car's regular brakes and forward collision warning system stopped working suddenly without any warning signs. This happened while driving, leaving you without braking assistance or collision alerts. The system may need diagnostic scanning to identify electrical or sensor failures, followed by replacement of faulty components.

While stopped at a traffic light, your brake warning lights (ABS, emergency brake, and traction control) suddenly came on and your brake pedal became much less responsive. You discovered Toyota had issued a previous recall for this exact problem involving the ABS actuator and pump, but the recall has expired and you're no longer eligible for the free repair, which now costs over $4,000. The repair will likely involve replacing the ABS actuator and brake pump assembly.

Your brake system warning lights (ABS, brakes, and stability control) came on when you pressed the brake pedal. A mechanic diagnosed the problem as a faulty brake booster and accumulator that need replacement. Toyota said your vehicle wasn't covered by a recall for this issue, and the recall period has expired. The problem occurred at 172,000 miles.

Your ABS, Brake, and TSC warning lights are all on, and your car is showing error code C1391 related to the ABS pump. You can hear the ABS pump engaging every few seconds while the engine is running, which isn't normal. The error code returns quickly even after you reset it. The ABS module may need to be replaced to fix this issue.

Your brake system has developed a leak in the accumulator (a pressurized component that stores brake fluid), which triggers a warning code C1391 and causes the brake booster pump to run continuously. When this happens, your brakes feel suddenly different because the regenerative braking system stops working. This is a known issue that Toyota has recalled before, but if your car is outside the recall/warranty period, you'll need to pay for the repair yourself.

There are issues with the brake. Many times the brake pedal goes down to the floor and it losses ability to stop. Apparently there is a common ABS actuator and Brake issues. Toyota will not address the issue

What component or system failed or malfunctioned, and is it available for inspection upon request? Brake Actuator failed requiring replacement of booster assembly with master cylinder and booster pump assembly How was your safety or the safety of others put at risk? This greatly impacted braking and stopping distance Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, Toyota Dealership Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, Toyota Dealership Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. These lights appeared after the failure - Brake, ABS, Traction Control

The contact owns a 2010 Toyota Prius. The contact stated while driving 45-50 MPH and depressing the brake pedal, the ABS, the traction control, and the check engine warning lights were illuminated. The contact stated that the vehicle experienced reduced braking power and the vehicle failed to respond as needed. The contact stated that upon engaging the brake, the vehicle decelerated, and the contact pulled to the base of an inclined side street, where the vehicle was able to stop. The contact was able to safety park and inspected the vehicle. The contact was able to drive to the residence at slow speeds. The vehicle was taken to the dealer, where it was diagnosed that the brake booster and master cylinder had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 94,000.

While driving on the freeway the Traction control light, ABS light, Brake System Light and Brake light all came on. Fortunately I haven't had any issues but when I took it to the a dealership I was told that the Brake booster and pump need to be replaced as the master cylinder was leaking into the brake fluid and given an estimate of $3500 for the repair. People online have said that after having this issue the brakes can go out at any time. I am unable to pay for the repairs at the moment so I have to drive with the knowledge of having my brakes going out at any time.

C1391 error, "Abnormal Leak of ACC PRESS". This is a common failure in many prius and requires the replacement of the brake master cylinder and brake accumulator. Toyota has an expired customer support program but no actual recall. Parts were replaced to bring braking system back into working condition.

I purchased a used 2010 Prius on May 1, 2025. On May 5, the car would not turn on. Thought it was the battery. Replaced the battery on May 6. On May 8, the battery was dead again. I jumped the car and tried driving it to the Toyota dealership to have it looked at. On the way a loud beeping sound started and the ABS light came on. I pulled over and noticed the brakes felt strange. After having it towed to Ourisman Toyota, the told me the brake booster was broken causing the battery to drain. The cost for repair is a little over $4,000. This almost half of what I paid for the vehicle.

Code diagnostic C1391 ABS system. I have replaced this in my previous 2009 Toyota Prius, it has been replaced in this 2010 Toyota Prius, and now needs to be replaced AGAIN in the 2010 Toyota Prius. It’s incredibly dangerous, no warning signs, spongy brakes all of the sudden that barely feel like they’re going to work. It puts not only myself in danger, but others especially when it just happens without warning and all of the lights come on as you are driving and the brakes become extremely wonky.

We have a 2010 Toyota Prius. All the sudden we got errors/warnings on our dash about ABS and traction lights, and brake light, staying on all the time. Brakes extremely sluggish, and from doing research advised not to drive it. Toyota did a diagnostic test which came up as C1391, bad ABS booster pump and master cylinder. This is a huge safety issue, others have reported brakes completely going out on the highway, and also reporting Toyota is not paying for fixing the issue, and only "certain Priuses" meet their criteria to pay for repairs. There supposedly was a recall at some point but we NEVER received it. I have contacted Toyota America and waiting to hear back. It is going to be very expensive to repair, about $3500-$4500. Yes, it is a 2010, but from what I'm reading and hearing is a MAJOR safety issue and Toyota needs to be held responsible and honor/extend any and all recalls. Again, I'm waiting to hear back from them, but was advised by many other Prius owners to file a complaint with NHTSA.

My brake booster master cylinder and pump assembly went out while driving on the freeway. My brakes became soft and unresponsive, though I was able to exit the freeway without incident. My ABS light, brake light, and traction control lights all came on. The lights have since remained on and my brakes continue to malfunction. My local repair show diagnoses the issue with the diagnostic trouble code: C1391 Back in 2018, before I owned the car, Toyota offered an "extended warranty" to have the parts replaced for free for 10 years or 150,000 miles, whichever came first. I'm past the year threshold but well short of the mileage one. I feel a recall should be made and the repair covered, as this is clearly a safety issue.

My ABS system light is on. The Toyota mechanic has determined that it is due to Nitrogen gas from a component of the brake booster pump assembly could leak into the brake fluid. As nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash. Toyota recalled model year 2010 Prius vehicles manufactured March 31, 2009, through October 9, 2009. I took my Prius to Toyota to fix this ABS recall problems but they are refusing to fix the problem for free. They are charging me $4000 to fix it.

ABS, traction, and brake warning lights came on. No OBD code reading. Mechanic says needs brake booster pump; brake booster master cylinder. Theoretically mine were serviced but no way for me to actually verify it happened on the recall. Vehicle located in Kamuela, Hawaii.

- Brake system failure - Safety risk due to longer stopping distance - Problem was reproduced and confirmed by two repair shops - Components were inspected by repair shop - Several brake warning lights were ON on dashboard AFTER failure occurred. Toyota recalled 2010 Prius vehicles for Brake Booster and Brake Booster Pump assembly failures. Recall code D0H. Toyota claims that the replacement parts are fixed for the gasket leak issue. Toyota replaced these parts on my car in 2013 as part of the recall. The replaced parts labeling are verified to be the claimed fixed ones. But only about 62,000 miles after the D0H repairs (odometer at 81,400 miles) the parts failed again on March 20, 2015. I do not put many miles on my cars. Toyota has put a maximum repair date for this issue knowing failures keep re-occurring (No repairs supported after 2019). Toyota has not fixed this issue given the repeat failures. Repairs for this issue is extremely expensive at more than $4000 at independent shop (parts and labor)

I am writing to express my concern regarding an issue with the PCS System dash lights on my 2010 Toyota Prius. I recently became aware of problems related to the brake booster system, which I understand have been addressed through recalls or warranty extensions on certain models. I believe that the issue I am experiencing should be covered under warranty, and I kindly request your assistance in resolving this matter.

I drove the car to my destination without any issues. An hour later, when I restarted the vehicle to leave, the following dashboard lights were on (slip indicator, ABS warning light, and brake system warning light). When I drove the vehicle, the brakes had diminished stopping power. It took farther for the vehicle to come to a full stop when applying the brakes. When we had it checked by the Toyota dealer we were informed that there was an abnormal leak in the accumulator assembly (system diagnostic code C1391) and it would need brake booster/master cylinder assembly with accumulator pump replacement.

Brake booster, brake accuater went out even after the recall. Dealership said they could do nothing to help

Dear NHTSA Team, I am filing a safety complaint regarding my 2010 Toyota Prius (VIN: [XXX] ) due to ongoing brake system failures. My vehicle is affected by Safety Recall D0H (Brake Booster Pump Assembly – Accumulator), but Toyota refuses to replace all necessary components for a proper repair. Issue Summary: •My brakes have intermittently failed, requiring excessive pedal pressure and causing delayed stopping, putting me at serious risk. •I took my car to Toyota on Edens for the recall repair, where Service Advisor David confirmed that the brake booster and accumulator should be replaced together. •However, Toyota will only cover the accumulator under Recall D0H, despite the brake booster being critical for safety. •My vehicle has Diagnostic Trouble Code (DTC) C1391, indicating an internal leak in the braking system, but Toyota refuses to cover the booster replacement. Toyota’s Response: •I contacted Jessica from Toyota’s Customer Experience Center (Case Number: [XXX]). •Toyota refuses to replace the booster under the recall, leaving me responsible for the cost, even though the dealership confirmed it’s necessary. •This decision leaves my car in an unsafe condition even after the recall repair. Request for NHTSA Action: 1.Investigate the safety risks related to this recall and the necessity of replacing both the booster and accumulator together. 2.Ensure Toyota properly covers all necessary brake repairs for affected vehicles. 3.Expand or modify Recall D0H to include the brake booster, as it directly affects braking performance. I urge NHTSA to take action before this defect leads to accidents or injuries. I am available to provide additional information as needed. Thank you for your time and attention to this urgent matter. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Abs lights on, traction light on .Actuator running cicle constantly . Breaks felt spongy

Break booster fail. Will cause the breaks to fail. There was a voluntary recall on these but I never recieveed the letter in the mail. Thr break booster failed after the voluntary recall was up. Toyota said they cannot help with this. Other prius owners i talked to have the same issue with their 2010 prius break boosters and also did not get the letter in the mail.

ABS Pump/Motor failed. Lost power and control over the breaks . ABS light on

Twice while I was driving on the highway, my ABS and brake light came on, and my brakes became less sensitive to pressure. That is to say, it took more effort and I had to push my brakes further towards the floor in order for them to respond. I went to an independent mechanic and got the code C1391 which indicates a brake pump accumulator issue. I went to a Toyota dealership and and had the car inspected. They confirmed the C1391 code and said the brake booster assy with master cylinder pump assy was malfunctioning. However, I was never told by Toyota that this issue meant my brakes could fail at any time. My safety and the safety of others was put at risk because my brakes spontaneously became less responsive, my stopping distance was increased, and they were at risk of spontaneous failure.

I was coming to an intersection where two cars were waiting for a right turn. I pressed on the brakes and nothing happened. The car continued to move without slowing down. The brakes felt "blocked" and unresponsive. I engaged the manual break at the last moment and that slowed me down. But I still hit the car in front of me which in turn hit another car in front of it. The police report says "following too close". But I was not following other cars. The two cars were already at the intersection. I was just coming to this intersection and attempted to slow down as usual. Except that the brakes did not respond. My car was a total loss.

I recently had an issue with the brake actuator on my 2010 Toyota Prius, showing error code C1391. This caused reduced braking efficiency, and research shows it’s a common safety concern with Priuses. While there was a recall, it has expired, leaving owners like me without support. I kindly request an investigation to address this critical issue for the safety of all affected drivers.

The contact owns a 2010 Toyota Prius. The contact stated that while her husband was driving 25 MPH, the brake pedal was depressed but the vehicle failed to respond. The contact stated that several unknown warning lights illuminated with an audible chime being heard. The contact's husband pulled over to the side of the road and depressed the brake pedal and the pedal went to the floorboard and the brakes started to respond as needed. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the brake pads and rotors needed to be replaced. The vehicle was repaired but the failure persisted. The contact stated while driving at an undisclosed speed, the brake pedal was depressed, and there was an abnormal sound coming from the brakes. The contact stated that the brake pedal went to the floorboard. The contact then towed the vehicle to the residence. The vehicle was taken to the dealer but was not yet diagnosed or repaired. The manufacturer was made aware of the failure and offered a Customer Satisfaction Program Extended warranty repair. The failure mileage was approximately 105,336.

The contact owns a 2010 Toyota Prius. The contact stated while driving at undisclosed speeds, while depressing the brake pedal the vehicle failed to come to a complete stop and the brake pedal was firm. No warning light was illuminated. The vehicle was towed to a local independent mechanic where it was diagnosed and determined that the brake module needed to be replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired due to the cost. The manufacturer was made aware of the failure. The failure mileage was approximately 117,000.

Please read the attached file "prius complaint signed" for a full description. I am the owner of a 2010 Toyota Prius, 2ZR-FXE. The warning light came up on my dashboard of my vehicle, so I took my 2010 prius to AutoZone, to get a free diagnostic. The diagnostic indicated the problem code of “C1256” “Accumulator Low Pressure” for the “Anti-Lock Brake System.” See Ex. A (AutoZone Diagnostic). It is available for inspection. According to the safety recall number “D0H”, 2010 prius model “2ZR-FXE” has a “Brake Booster Pump Assembly which can develop a crack inside the accumulator housing. If this occurs nitrogen gas could leak into the brake fluid and gradually cause a loss of power assist. Under certain circumstances, THIS COULD AFFECT STOPPING DISTANCE AND INCREASE THE RISK OF A CRASH.” (Emphasis added). I have noticed that when I brake hard, IT TAKES LONGER TO COME TO A STOP, WHICH THREATENS NOT ONLY MY LIFE, BUT THE LIVES OF MY WIFE AND TWO [XXX] DAUGHTERS WHO ALSO RIDE IN THIS VEHICLE. According to the safety recall, “Toyota dealers will perform an inspection and, if necessary, replace the Brake Booster Pump Assembly at NO CHARGE to the vehicle owner . . .” See id. The safety recall does not explicitly permit dealers or servicers to charge for an inspection with regards to this defect, according to the information provided me. The estimate, provided by DARCARS recommending replacement of the “BRAKE BOOSTER WITH MASTER CYLINDER WITH PUMP[,]” confirms that the issue appears to be that which is covered by the safety recall. Ex. F.; see also Exhibit B Safety Recall (The vehicle has a “BRAKE BOOSTER PUMP ASSEMBLY WHICH CAN DEVELOP A CRACK INSIDE THE ACCUMULATOR HOUSING . . .”). See also Exhibit E Error Code from DARCARS (“C1256 Accumulator Low Pressure”). Nevertheless, DARCARS refused to waive the diagnostic fee of $150 and would not repair the vehicle unless I paid them “$5,150.” See Exhibit F. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My brakes stopped braking but luckily I could drive slowly into a curb in my neighborhood. God knows what could’ve happened if I was on the freeway. All the dash lights came on at the same time so I ran some codes; it came back C1391 - the brake actuator is broken. Toyota will not cover it despite this being a very common issue. My car is undriveable until this gets fixed because it will not break.

The contact owns a 2010 Toyota Prius. The contact stated while driving approximately 40 MPH and depressing the brake pedal, the brake pedal was stiff and required excessive force to depress. The contact stated that the ABS, Stabili-trac, and Parking Brake warning light was illuminated. Additionally, the contact stated that a chime sounded and could not be turned off. The contact stated that the failure had been intermittent but was a recurring failure. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes). The manufacturer was not informed of the failure. The failure mileage was approximately 77,000.

hope this message finds you well. I am reaching out regarding a potential recall issue with my 2010 Toyota Prius. The vehicle's VIN is [XXX] , and I am currently located in the Austin area. Recently, my vehicle has been experiencing problems related to the brake system, specifically the brake booster pump assembly. The diagnostic results returned codes C1241, C1391, and C2300, which point to issues such as abnormal leaks in the accumulator pressure and actuator system malfunctions. Given that this issue may fall under a recall or extended warranty for the brake booster pump assembly, I would appreciate it if you could confirm whether my vehicle qualifies for this service. If it does, I would like to schedule an appointment to bring my car into the nearest authorized service center to have the necessary parts replaced. Please let me know if any additional information is needed. I look forward to your response and would greatly appreciate your assistance in resolving this matter as soon as possible. Thank you for your time and support. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Toyota failure to honor recall. See correspondence below for NHTSA ID and other detail. NTHSA Recall ID: 13V235000 Toyota Case#: [XXX] Very dissatisfied with Mr. Lxxxx's denial of our inclusion in the customer support program. He seemed to reach for every imaginable escape hatch to say "no". Claiming 2 notices were sent out (to the correct address) between December 2017 and March 2018, neither of which reached me, is dubious to say the least. The likelihood of our remaining a Toyota "family" with the eventual replacement of our 3 vehicles (including a previously unmentioned 2017 Rav4) has shrunk considerably. Shame on Toyota North America. ---------------------------------------------------------- (earlier Monday, October 21, 2024 at 11:31:54 PM EDT) Dear Mr. Oxxxxx: I’m writing to express my distress at being disqualified for this expensive safety recall about which I was never notified by mail and, despite receiving maintenance and inspections at the dealership in slim 2-year period between the mailer and the expiration, was not notified of the recall. The phone agent, Ms. Xxxxxx, was very courteous, opened the case, and informed me of the 2018 mailing about the recall, which I did not receive. I’m quite diligent about recall notices, we are a Toyota “family” with a Sienna in addition to the 2010 Prius, and records will show we’ve always attended to recalls for which we’ve been notified, going all the way back to our first purchase of a new Camry in 1997.

In August of 2024, my 2010 Prius with less than 100,000 miles - all the brake warning lights on the dash suddenly came on - without any prior warning. The brakes felt a little "funny" at the time, so I took it to my mechanic immediately because my safety or the safety of other was at risk if the brakes completely failed. My mechanic informed me that there was a TSB for the brake booster with master cylinder and brake booster pumps that Toyota new about. I felt that it was imperative that this was repaired immediately. Apparently Toyota knew about this issue but did not notify me in any way at any time. I bought this Prius new and have had regular service check ups. I had to pay nearly $5,000.00 to have this repaired which I feel that Toyota should reimburse me, and any others who had this problem.

ABS and brake lights lit at around 141000 miles code C1391 came up during diagnosis.

Brakes started making a hissing sound a couple of weeks ago. Yesterday evening when I was driving on freeway , I got an assortment of lights on my dash while driving . ABS was instantly disabled and it was significantly harder to brake the car. BRAKE light on dashboard came on. Traction control light came on . It was very dangerous and it was mere luck that there was no car in the front - otherwise I could have crashed. Pulled over to the side on the freeway and then came in internal roads to my destination , keeping a lot of braking distance and at slow speed. Turns out this is the infamous brake booster leak that was so bad Toyota was forced to create an extended warranty program on Gen 3 to fix it. Brought it to dealer next day. Got an estimate for $4000 for "REPLACE BRAKE BOOSTER AND MASTER CYLINDER(DUE TO INTERNAL LEAK)"

The contact owns a 2010 Toyota Prius. The contact stated that while driving at various speeds and the brake pedal depressed, the vehicle lunged forward. On a most recent occasion, the contact was attempting to park the vehicle and after shifting into the park position, the vehicle lunged forward as the brake pedal was depressed causing a minor collision with a curb and another vehicle. The contact mentioned the brake pedal required excessive force in order to come to a stop and that there was an abnormal noise present. The contact was concerned that the failure would progress causing a severe accident. A police report was not filed and there were no injuries sustained. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS System failed and advised the vehicle be taken to a dealer. The vehicle was not repaired. A dealer was not contacted. The manufacturer was not notified of the failure. The failure mileage was not available.

Toyota refuses to cover a recall that I was never made aware of. My Prius need to have ABS Brake Accumulator and other components replaced. My VIN I was told had a recall but I was never made aware. I was told it may not be safe to drive my car. Toyota told me I would have to cover all cost for the repair and for my family that is just not possible. For the safety of my family, I am hoping NHTSA can help me in anyway.

NHTSA CAMPAIGN ID: 13V235000 Toyota will notify owners, and dealers will replace the affected brake booster pump assemblies. The recall is expected to begin late July 2013. Owners may contact Toyota at 1-800-331-4331. Toyota is no longer honoring this recall. They think it is acceptable for me to drive around with unsafe and defective brakes.

In 2015 I purchased my Toyota Prius in VA. I now live in Indiana and had my car checked for a possible sensor issue because the traction, brake & abs light were coming on and off. The diagnostic showed a brake accumulator leak malfunction. I contacted Toyota dealership once I was told there was a recall. The dealership said that it was showing it was replaced in 2013 from the previous owner in VA. It was listed then as a recall. I contacted Toyota Corporate and they said that it went from a recall to customer support with a maximum of 150,000 miles. I did not have any more problems until just recent. My argument is once a recall it should still be repaired. The part appears to be the problem. It is a safety issue and I need Toyota to fix the problem. Thank you!

ABS Lights turned on and need replacement. This is my 3rd Prius that have the Issue.

The contact owns a 2010 Toyota Prius. The contact stated while at a complete stop and attempting to depress the accelerator pedal, there was an abnormal vibration coming from the brake pump. The contact also stated that when the vehicle was turned off, the vibration on the brake pump occurred, triggering the alarm on the vehicle at least one time per day, each day. The vehicle was taken to an independent mechanic where the failure was related with an unknown recall. The vehicle was not repaired. The manufacturer was made aware of the failure; however, no assistance was provided. The failure mileage was approximately 196,000.

The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds, the brake pedal would depress to the floorboard initially without warning. Over time, the brake pedal had become stiff upon depression with several warning lights illuminated on the instrument panel. The vehicle was taken to an independent mechanic where a code reader confirmed a defect with the braking system. The vehicle was then taken to another independent mechanic where the vehicle was diagnosed with a defective brake booster. The mechanic then informed the contact of NHTSA Campaign Number: 13V235000 (Service Brakes) which was linked to the failure. The dealer was notified of the failure and informed the contact that the vehicle was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 153,000.

Prius Gen III has a known defect with failing Brake booster parts. In Nov 2023, while driving my 2010 Prius (~160K miles), suddenly brake, ABS, Traction control, skid indicator lights popped up on the dashboard and I have lost the ability to brake effectively. There was a brake pressure loss and I had to slam hard the brakes to slow the car. The error code was 'C1391' and the mechanic diagnosed it as failure of Brake booster parts ABS Brake booster pump (accumulator) - part#47070 47060 and Brake master cylinder (actuator), part#47050-47140 and he replaced both these parts. Toyota is aware of these failures which are very frequent and hence they issued a brake booster “customer service program” ZJB - which extended the warranty for these parts. But many of us were not covered by this warranty either because of the time or mileage restrictions. This was a costly repair and we had to fix it out of pocket at the cost of ~$3000 as this is safety hazard without proper braking. To make matters worse, 3 months after the repair, the newly installed parts failed again and I had to go through the same repair. I called to Toyota to complain about this and they cannot do anything about it and advised me to report it to NHTSA.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at 55 MPH, with the brake pedal was depressed and went to the floorboard. The contact stated that the brakes failed to adequately slow the vehicle. The ABS warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the brake booster. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 120,000.

Brake booster assembly failure. Code C1391 - accumulator pressure leak. Toyota previously agreed to extend the warranty on this part on this year of Toyota Prius due to the known issue and the time limit for this repair was set to be in 2019. Toyota agreed to replace the unit only if it fails before that timeframe. My Toyota got recently affected by this issue resulting in over $3,000 estimate for a repair as Toyota no longer covers this repair for my vehicle. That’s a known issue with this part, Toyota knows it’s faulty and yet no recall has been issued. Now I have to pay for a repair out of pocket. I can’t drive the vehicle until it’s fixed. This should be handled as a recall with all faulty units being replaced regardless of millage. A few people opened lawsuits on this issue before and some got a settlement. I believe there is enough evidence that this should be classified as a recall and a free of charge repair should be provided to the owners. The brake booster unit has been buzzing a lot for quite a few months ( due to the pressure leak it had to work more than normal). Now it completely failed with the leak being so excessive that the brakes are very soft.

I’m encountering multiple dash lights with the brakes being very unreliable and no that’s no regenerative breaking. I checked with an obd2 kit and the app shows that I have a code C1391.

Faulty brake boosters that crack and leak, making brakes unusable and draining the battery (diagnostic code C1391). There was a Toyota service repair where they exchanged the faulty brake boosters with properly working ones, but it has lapsed.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed and attempting to slow the vehicle, he became aware that the brake pedal required excessive force to bring the vehicle to a complete stop. The service brake warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the brake booster and brake master cylinder. The vehicle was not repaired. The vehicle was then taken to an independent mechanic, who confirmed the diagnosis and additionally found that there was a leak in the brake fluid accumulator, resulting in low brake fluid pressure. The vehicle was taken back to the dealer, who added brake fluid to the braking system, which seemed to temporarily resolve the failure. The manufacturer was not notified of the failure. The failure mileage was 140,000.

[XXX] We took in 2010 Prius to Toyota Dealership in Pharr Texas because road hazard light, ABS , Brake and low tire alarm came on while driving car. They ran diagnostic and found out that the brake pump assembly and brake cylinder assembly has to be replaced. We called Toyota Cooperate to ask for assistance to pay for cost and after 4 weeks of reviewing issue they said they could not help us because the CSP had expired. This car was given to us by a friend of ours and they had not used it for 2-3 years so we got it we repaired and got car running again. After we drove it we came across this problem with the brakes. This car was was built in the same plant as the other recalled cars going by by the vehicle number . We believe that the CSP should be extended or changed to a Recall? Will you help us or direct us to whom we can contact with this safety issue? I have the Toyota diagnostic report from Toyota and Toyota Corporate Letter on email. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A warranty extension went out a few years back that said one might receive a "CHECK PCS SYSTEM" warning on the dash. This has happened to us, along with 7 other lights on the dash. Between the brakes being much less responsive, and all of the pre-crash warning / adaptive cruise / radar features being disabled, this could have caused an accident. The dealer checked out the car and states that the brake actuator has a leak and that it will be a costly repair - no less than $3000. This suspiciously all happened *just* outside of the warranty window (we are within the allowed number of miles but just out of time), and also suspiciously after Toyota released an upgraded version of the actuator, and *also* after a bunch of people are experiencing the same failure. Our best assessment at this time is that the brake actuators have a factory defect and that a recall should be done.

The brake accumulator has failed on my prius which then deactivates regenerative braking, traction control, abs, and stability control. The lights for traction control, ABS, and stability control and parking brake are shown on the dash. The result for the driver is that the brake pedal has the same pressure, but does nothing until about 25% of pedal travel. At this point, the mechanical brakes will engage and provide a very sudden and jerky application to the brakes. In other words, a very non-linear brake control is present and is incredibly difficult to predict. If this vehicle is operated on the motorway, the safety of the vehicle's occupants as well as others on the road is greatly reduced. Street Toyota has confirmed this issue and its effects. They want to charge $3600 to fix this issue even though the car is only worth $5k. This problem has been investigated in the past buy Toyota and the NHTSA. Toyota has applied an extended warranty for this part meaning that they will only replace it once it goes out. They also failed to notify their consumers about this matter. It is a serious issue that has put many lives at risk and has caused multiple injuries. It is a matter that should not be ignored by either the NHTSA or Toyota.

I noticed that the ratcheting parking brake pedal has stopped ratcheting correctly, and I planned to have it inspected on the next scheduled maintenance. Recently, the brake system illuminated the traction control, ALB and "BRAKE" lights simultaneously, and the braking power diminished by more than half, with no braking until the pedal was halfway down. I depressed the parking brake pedal a few times, which cleared the "BRAKE" symbol and the problem stopped and normal braking returned. This has now happened three times with the same fix. It appears that when the "BRAKE" symbol is no longer illuminated, the problem goes away. This appears to be a software problem that triggers a braking problem to engage the traction control and ABS icons when the "BRAKE" icon associated with the parking brake is illuminated. This web site has other instances reported with the same symptoms, and Toyota had a service bulletin, which has expired, which leads to a $2000-$3000 repair bill to replace a brake booster. It appears to be software related to me, not mechanical. It poses a safety risk because braking performance is severely compromised with no warning. NHTSB needs to look into this, as rear end accidents can easily happen if strong braking in heavy traffic is required to avoid a collision. I recommend that a recall be established to fix this. An alternative cause may be a misaligned micro switch in the parking brake mechanism, which has been experiencing problems. This could lead to the "BRAKE" light being illuminated, and sending a bad signal to the computer.

The contact called the local dealer, but the vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic and the contact was informed that the brake booster assembly needed to be replaced. The manufacturer was contacted, but no assistance was provided. The approximate failure mileage was 139,999.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the contact depressed the brake pedal and noticed an abnormal humming sound. The contact stated that the failure had been intermittent since 2016. The contact stated that the failure had become persistent. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but did not assist. The failure mileage was approximately 296,842. The VIN was unavailable.

Recently, I had ABS failure in my vehicle and warning lights came up on my dash with code C1391 which indicates a problem with brake booster assembly and pump. Now I am afraid to drive it because the brakes seem that they could fail at any time and I cannot break quickly when needed. Toyota is aware there is a problem with the brake booster assembly and pump based on prior Customer Support Programs (my vehicle was not included since warning lights were not present at the time), class action lawsuits, and petitions to NHTS about this issue. I believe the problem is prevalent enough and brakes are significant for driver safety that there should be a safety recall. My vehicle has less than 150,000 miles. I called Toyota to complain about the problem as I know it is very common among Prius owners, but they have said there is nothing they can do.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS and brake warning lights remained illuminated, and the brake pedal was firm while depressed. The contact stated that the vehicle failed to immediately stop while depressing the brake pedal, causing the stopping distance to be extended. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 120,000.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the traction and ABS warning lights illuminated. The contact stated that the brakes were inoperable. The contact stated that he was driving at a low speed and was able to safely stop the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed with a failed brake booster. The contact was informed that the brake booster needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but did not assist. The failure mileage was approximately 227,000.

While operating the vehicle at normal highway speeds, the car suddenly had the ABS, Traction Control, and Brake lights all come on. The vehicle did not operate or sound any differently at the moment all the lights came on. However, over the next week there developed a mild humming coming from somewhere in the engine bay approximately behind the dashboard. My mechanic identified the problem as the brake booster and pump assembly failing and informed me that the vehicle may drive normally for sometime but the brakes will fail suddenly once the brake booster and pump fully fail. Thus, making operating the vehicle extremely dangerous. I am currently waiting for a Toyota specialty mechanic to become available to replace the brake booster and pump assembly at a cost of +$3,000. Please investigate this issue, there are many people experiencing this issue with the 2010 Prius models.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at 40 MPH, the vehicle consistently made abnormal sounds and jerked forward while the brake pedal was being depressed. The vehicle became inoperable. Several unknown warning lights were illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the failure was due to a crack and leak in the brake booster. The vehicle had not been repaired. The contact referenced the NHTSA Campaign Number: 13V235000 (Service Brakes). The manufacturer was made aware of the failure and determined that the vehicle was no longer under warranty. The failure mileage was approximately 65,000. The contact stated this is a known manufacturing fail for the brake booster 2010 Prius.

My brakes behave strangely cause i experience inconsistent brake feel after actuation during slow and steady application after brakes on rough or slick surfaces.also, All three lights ABS light,brake light and VSC come on and off on dashboard at the same time.

A couple weeks ago we were driving our 2010 Toyota Prius and 3 brake lights came on: BRAKE, ABS, and a car with squiggly lines behind it. We took the car into the Toyota dealership ($209) to perform a diagnostic. Their results are as follows and I quote: "Hydraulic Brake Booster Pump DTC C1391 Abnormal leak in accumulator. Has T-SB and CSP that are both expired. Recommend perform repair outlined. Recommend R&R Brake Actuator Assy, Booster Pump Assy and perform ABS ECU Reflash. We wouldn't have purchased this car had we known a few years later we'd be facing a $4400 charge Toyota wants to charge. We don't have the funds let alone go now and purchase another car.

Slip indicator symbol, Brake word, Brake symbol, and ABS word lit up while driving. Brake pedal had to be pushed further down to stop the car. No warning lights or issues before this incident. Toyota diagnosed as abnormal leak in accumulator and internal brake fluid leak, and quoted replacement of the brake booster assembly with master cylinder and the brake booster pump. There is no advance indication and the brake booster will not be available while driving. Toyota recalled selected vehicles. There are currently many reports online from vehicles excluded from the recall that are affected by the same brake booster malfunction and warning lights.

The brake booster assembly and brake booster pump have failed due to a vaccine leak internally in the brake booster. Failure of the brake booster can cause the vehicle to be more difficult to stop. Yes the failure codes have been reproduced. The vehicle falls “out of warranty” for a part that should last the life of the vehicle. Replacement of the part is quoted over 4,000 dollars. The abs light, brake light, and traction control lights.

The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds and depressing the brake pedal, the brake pedal was firm and difficult to depress. The contact stated that that the brake pedal was pumped to stop the vehicle. The contact stated that the ABS and stabili-trak warning lights were illuminated and an “Exclamation Mark" message was displayed. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the brake master cylinder and brake booster pump needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 10V039000 (Service Brakes, Air). The manufacturer had not been informed of the failure. The failure mileage was approximately 138,000.

Due to insufficient corrosion protection, the rear brake line of my 2010 Prius burst as I pressed the brake pedal in my driveway. It dumped ALL of the brake fluid onto the ground within a couple of minutes. Imagine if I had been driving!! There could have been a serious crash!! This was sudden. There were no brakes! Pedal lost all pressure and went to the floor when pressed. Lots of warning lights and alarms screaming inside car. The vehicle has been inspected and repaired at the Toyota dealer as of 10/03/2023. I have pictures of the failed part when it was installed on the car. If the dealer is contacted quickly, they might still have the actual failed brake line (which I was charged disposal fees for.) This was very scary and numerous lives could be at risk due to the popularity of this car and its use in rideshare/taxi service. There were no warnings prior to this. Brakes worked normally. Car is well maintained with dealer service records. There is no excuse for not properly trading such a critical part for corrosion, just to save money. Peoples lives are at stake!! It's the BRAKES of the car!! Someone needs to investigate this! I have pictures and receipts I can provide.

I was driving and all of the sudden lights came on, on the dashboard and when I started to slow down, I noticed the brakes were very "mushy" and barley worked. I then drove it directly to the dealership and on the way the lights went off, and brakes went back to normal. This is a very dangerous situation for anyone to be in and I don't know why NHTSA has not made this a mandatory recall for Toyota, I did find a recall # 13V235000 (which needs to be extended). The dealership said it would cost $3,000 to replace the Brake Booster Pump Assembly and Master Cylinder. This type of repair should be recalled, and NHTSA should get this resolved with Toyota ASAP.

Affected by the recall number 10V036000, the 2010 toyota prius is manufactured with a defective brake booster and master cylinder system which causes defect of the brake system, and causes my vehicle to often lose power in abs and randomly lose abs power braking, making brakes hard, and makes for longer stopping distance. This is a problem for many and obvious reasons on the road regarding safety. All vehicles should have optimal braking systems for the road, and should otherwise be repaired at no cost if the car is manufactured with defect. This has caused no accident for me yet but the abs has failed on many occasions. I have read at least 100 cases of this given vehicle under this recall being caused an accident with faulty brakes, and sometimes complete failure to stop which is extremely worrying. This recall excludes vin numbers past a certain date, yet the recall in question is certainly still affecting many cars, as capistrano toyota has also called for petition of toyota to repair at no cost for all affected vehicles. Yet all dealerships have denied my request and toyota has no formal coverage regarding the rest of the faulty vehicles they manufactured.

Known problem for Prius with limited manufacturer liability. My breaks started failing, I am being quoted at $4000 in repairs and labor. My car is 3 years older than the recall parameters but within mileage. Manufacturer won’t cover anymore since it’s past due

Brake system failure. ABS light / Brake Light / Traction Control light. There is a recall but expired. Code C1391 need to replace Brake Booster and Brake pump. Recall should have included my car. 1,500.00 plus parts only. recall should be extended.

Hello on my 2010 Prius the ABS, Brake, Traction Control lights are all on lit up on my dashboard. Brakes are making loud noise when I stop the vehicle. I took the car into my local dealership service department. I’m being told that the brake booster and master cylinder needs to be repaired. This was a part that was put under an extended warranty with Toyota but now it’s no longer being covered by the warranty. So they want me to pay out of pocket to fix. I would like to report that they should honor the warranty agreement for my vehicle.

The contact owns a 2010 Toyota Prius. The contact stated while driving 45 MPH, there was an abnormal sound coming from the front driver’s side of the vehicle. The contact stated that the traction control, brakes, the Pre-Collision System (PCS), and the ABS warning lights were illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the brake actuator and the brake booster to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with the TSB: POL1803, however the vehicle was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 143,000.

To submit a claim to the NHTSA regarding my 2010 Toyota Prius (VIN [XXX] ), I wish to highlight a concerning issue with the brake booster, actuator, and brake booster pump assemblies. This malfunction has the potential to lead to brake failures, posing a significant risk of collisions with other vehicles. The presence of a diagnostic trouble code (C1391) and the illumination of ABS, traction control, and exclamation symbol lights, coupled with an audible whirring sound during braking, underscore the confirmed nature of this problem. This whirring sound initially emerged a year ago, accompanied by temporary dashboard light activation, which eventually subsided, while the whirring sound has persisted. Toyota has initiated an extended warranty program labeled (ZJB), encompassing a span of 10 years from the initial usage date or until 150,000 miles are reached, whichever comes first. Regrettably, my vehicle's mileage has exceeded 182,000 miles over the stipulated 150,000-mile threshold, and its age surpasses 13 years, rendering it ineligible for inclusion in this program. The actions of Toyota appear to prioritize financial gains over the well-being and security of countless drivers and passengers who are potentially endangered by these defective brakes. Their stance is exemplified by the reluctance to offer a comprehensive solution. I find myself compelled to bear the burden of approximately $3,000 in brake-related expenses at dealerships—an unjust imposition on consumers, given Toyota's distribution of flawed components that jeopardize safety and lives. Toyota's response has been inadequate, limited to extending warranties and performing repairs solely on vehicles that have already experienced brake failures. This approach neglects the prevention of potential injuries or fatalities that could be averted through proactive measures, such as issuing a full-scale recall. In light of these circumstances, I am seeking redress through the app INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My brakes are not working effectively. They are not engaging as they are meant to.

Brake booster failed while driving. Warning light ABS, traction control and brake light lights up. Lost power brake. Car is hard to stop with the manual brake in the fail safe mode. with C1391 code logged. Toyota had an ZJB warranty extension but my car is not covered because the warning light did not show during the 10 year window. The brake booster fail appear common and should be cover by a recall instead of a warranty extension.

Brakes take longer to apply with weird noise. There is a weird sound. Brakes are fine not worn. Mechanic says bad abs actuators which should not have failed since should last life of car. There was a recall on this but my car not in the vin search not sure why. All problems described in that recall is what I am experiencing.

Brake system failure. ABS light / Brake Light / Traction Control light. Low mileage car. Likely the last Hybrid I would buy. $4000 to fix. Almost what I paid for the vehicle. There is a recall but expired. Should be by mileage not time!

There's existing problem right now in my vehicle that braking is less responsive and also the ABS, EMG brake lamps and Traction control lights are on the whole time on my dashboard. I took it to the mechanic and he found out that Theres a problem with the Brake Booster Pump Assembly which developed a crack inside the accumulator housing. As result nitrogen gas could leak into the brake fluid and gradually cause a loss of power assist. Under certain circumstances, this could affect stopping distance and increase the risk of a crash.

Even though a related recall has already been performed 4 years ago, my vehicle is exhibiting the same brake safety symptoms: - 3 dashboard lights all illuminated: BRAKE, ABS, and traction control (anti-slip) - brake accumulator pump noise occurring at 5 second intervals - regenerative braking and ABS are non-functioning - error code C1391 appears via OBDII The above symptoms appeared two weeks ago (6/14/2023), and on 6/16 an independent service center that specializes in foreign vehicles (including Toyota) confirmed the symptoms and error code, and said that the vehicle is unsafe to drive due to impending brake system failure. Toyota dealer indicated newer brake system parts are available to address the issue, but would need to be installed at my cost. The symptoms appeared while driving the vehicle at freeway speeds commuting to/from work. The vehicle is available to be inspected, however, I have already scheduled a repair (at my cost) because we use it daily for work.

The break booster started making a noise and my car should have fallen into the range of the previous recall for the exact part. I cant afford to change it so I continue to drive it and all of sudden the breaks are so hard to push and a constant buzz is going off! Autozone confirmed it was the break booster ans abs then a private shop did also

ABS pump booster failed. Hard to stop the vehicle. Almost had an incident. Trouble code C1391.

My ABS, break and anti-skid lights came on while my vehicle was parked. The ABS system shouldn't fail on a car. Many other 2010 Prius owners have reported the same problem. Toyota had break system recalls back in 2010 and 2013. I believe my car may should have been part of the recall, but was overlooked.

I took my vehicle to my mechanic at my independent service center because I experienced shaking/significant vibrating at 60 mph. I had also experienced a loud noise that only lasted about 2 miles. He found that the right rear brake unit, specifically the caliper, had seized. I contacted Toyota of America because there was no brake warning light to alert us of this situation. I received a call back from David from Sloane Toyota in Glenside, PA, who confirmed that the caliper seizing would not cause the brake warning light to appear. He also indicated that the caliper is not something that is routinely checked as part of state inspection, or the regular maintenance schedule. I am deeply concerned that this mechanical failure of the brake unit could have resulted in death(s). I request that Toyota vehicle owners and mechanics be alerted to this, specifically the fact that the brake warning light does not alert a driver of this brake part failure. Further, I request that an inspection of the calipers be included in the routine maintenance schedule and annual state inspection. Thank you for the work that you do to keep us safe!

ABS brake booster failure. Vehicle with approximately 140,000 miles. Previous safety notice expired that covered 10 years or 150,000 miles

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS warning light and two other unknown warning lights illuminated. The contact stated that the brake pedal went to the floorboard while depressed. Additionally, the contact stated that while self-inspecting the vehicle, he became aware that there was no brake fluid in the brake fluid reservoir. The contact stated that when the vehicle was self-inspected for a second time that same day, the brake fluid was full. The vehicle was taken to an independent mechanic, who informed the contact of an unknown recall for the brake booster. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 85,000.

There was some kickback or resistance when engaging the brake to start the car. When the car turned on, the brake light, ABS light, and traction control light lit up. I took the car to Toyota service, they stated that the brake booster pump was defective and needs replacement. I see that there is not an open recall for this vehicle, however there was a recall #13V235000 that was sent out in 2013 with the exact same issue for 2010 Toyota Prius. We bought the car as a certified Pre Own in 2015, so we did not get this notification. I am trying to figure out why this car does not fall under the recall category? Thank you.

The braking system developed a leak in the accumulator causing the whole braking system to fail and turn the abs light on in the car as it leaked brake fluid into the brake booster from the master cylinder

Almost caused a major accident. Brakes failed with no warning!

My Prius 2010 has thrown the ABS, Traction, and Brake HUD lights all together. I took it to an Autozone and scanned the code to get the C1391: Abnormal Leak of ACC PRESS error. Many Prius 2010 have this issue, I'm sure I'll need to replace the actuator and/or accumulator and I know that will cost a good bit, i hope Toyota could help us fix it.

I was driving and all of the sudden lights came on, on the dashboard and when I started to slow down I noticed the brakes were very "mushy" and barley worked. I then drove it directly to the dealership and on the way the lights went off, and brakes went back to normal. This is a very dangerous situation for anyone to be in and I don't know why NHTSA has not made this a mandatory recall for Toyota, I know why Toyota does not recall $$. They are now making $$ on parts and their dealers are making $$ on this service. I did not find a specific recall on the NHTSA website but I did find a recall # that I will be looking into in more depth. That recall number is 13V235000. The dealership said it would cost $3,000 to replace the Brake Booster Pump Assembly and Master Cylinder. If I were someone with very little funds to get this repaired then I would drive the car as my only source of transportation. This type of repair should be recalled and NHTSA should get this resolved with Toyota ASAP.

I was driving in my neighboorhood and as I went up the wall bridge my acceleration stalled and my ABS light, Check engine light, and check hybrid system light came on simultaneously and started beeping. At the same time, I lost my braking ability completely. I had to swerve off to the grass in the hopes of not hitting turning traffic at the stop sign. Luckily, it stopped before doing any major damage to anything. Thankfully, I was close to home and was able to put it in my driveway safely. The check engine light then cut itself off, but my brakes remained completely nonfunctional. If this had happened on the highway or a busy road I'm sure it would’ve been much worse.

ABS system and traction control lost. ABS booster pump and master brake cylinder broke down. They should be life long parts. Brakes lost its function on highway and was pretty dangerous. ABS light, traction control light and brake light on. Dealer refused to change on their own.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at various speeds, the vehicle started to hesitate. The ABS and traction control warning lights were illuminated. The contact stated that there was brake message displayed. During the failure the brake pedal had to be depressed twice before the vehicle responded. The vehicle was taken to the local Service Center who diagnosed that power brake booster and master cylinder needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the vehicle did not qualify for the Extended Warranty related to the failure. The local dealer was not yet contacted. The failure mileage was 135,000.

I noticed that my brakes felt mushy when applied. The ABS light came on in my car. I took it to 2 different Toyota dealers and both said that my break boosters were failing and would need replacing. I had 125,000 miles on my car. The brakes were working adequately at that time, but I was aware that they could fail at any time and put me in danger. I was charged $3637 for diagnosis and repair on 12/6/22.

The contact owns a 2010 Toyota Prius. The contact stated while his wife was driving 40 MPH, the traction control, ABS, brake warning light, and other unknown warning lights were illuminated. The contact's wife was able to drive to her residence. The contact stated that he was an independent mechanic and he had diagnosed that the failure was related to NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The vehicle was towed to the dealer but was not diagnosed nor repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 192,000.

My 2010 Toyota Prius (JTDKN3DU3A1307523) had the ABS/brake warning/traction control (VSC) lights come on at the same time and I lost a significant portion of my braking ability, while driving. I was able to pull into a shop. The mechanic connected a code reader to the OBD II port and found the code DTC C1391. It is a failure with the ABS booster pump assembly and accumulator. I called Toyota corporate line and they said there was an expired Customer Support Bulletin, which I did not receive mail alert for, and that it is not a recall, and that the customer is on the hook for replacement of the failed component. They repeatedly told me it was not under recall, even though internet forums all mention it as a recall campaign. I called auto shops in my area (specializing in Toyota and Japanese makes) and they all did not want to perform the repair as they found it too complicated to do, and told me Toyota has a recall campaign and advised I call Toyota corporate to get serviced.

The brake cylinder and brake pump assemblies broke down in the middle of the highway. The ABS, brake, VSC, and traction lights lit up unexpectedly after ~1 hour of driving. I was able to get the car to the dealership and the service advisor noted that he was surprised that we made it as far as we did without a complete failure of the brake system. He advised that it was not even safe to drive the car around the corner for a few blocks because of the brake system malfunction. They provided an error code of C1391. This is a full failure of the brake system that makes the vehicle unsafe for street operation. This complaint adds to an already well-documented problem with these issues that Toyota acknowledged through a wholly inadequate "voluntary customer support program" which expired after the earlier of 10 years and 150,000 miles [link: https://bit.ly/3CntosU], which for all 2010 Priuses expired in 2021. The issue also appears similar to the ones reported in Defect Petitions DP19-004 and, indirectly, PE10006. This was also the subject of a lawsuit in 2020 that was since withdrawn by the plaintiff (Turner v. Toyota, Case No. 5:20-CV-00320, CD Cal). There are dozens of written reports and videos of people resetting their brake warning lights with paperclips. This is a major safety hazard for those 2010 Priuses that are still on the road and should be remedied by a recall.

My 2010 is covered under a recall. I had total brake failure and the dash light up like a Christmas tree. Brought in before the recall was released and it was repaired under my extended warranty. Then got recall notice, so I guess there was an internal fund transfer.

The braking system malfunction and it's available for inspection upon request. I was almost get into accident when I was driving around 65mph on I-495 because of the fail brake issue Upon online research, it turns out this is a common safety problem on the 2010 prius and toyota only issue extended warranty but not recall. the ABS light, slip Indicator light and brake system light all come on at the same time before I experienced the brake system failed

My 2010 Toyota Prius seemed to have a faulty ABS actuator/ boaster pump for years but I did not know it until recently. For years the car would display the abs, traction controls, and brake light for 50 miles and then go away but the most recent time it did not go off. The actuator continuously runs and you can hear it consistently buzz every 5-10 seconds. The brake pedal require a lot more force in order for the car to slow down and the car jumps forward when depressing the brakes suddenly. In the past the brake would require much more force but after a few miles on the road the light would go off and the car would seem to function as normal, but most recently as of last week the light would not go off and the brakes require a lot of force still after doing almost 400 miles. I had 2 near misses once almost hitting another car during a rainy day and another missing a stop sign by almost half a car length. I took my car to the dealership and they stated that the error code is showing a faulty abs actuator but the rep told me it should still be fine to drive if I do not want to pay the out of pocket cost and get it fixed immediately. This is a major safety concern for me and my family and even though I been servicing my car for year at the Toyota dealership it was never brought to my attention. Only recently when I had the near misses and had my mechanic run test on it did I realize. I then took my car to Toyota for routine maintenance and it was confirmed that the abs actuator/boaster pump was faulty, yet they offer no remedy and they never even notified me of this faulty OEM issue until I brought it to their attention. The dealership said my VIN did not qualify for any recall or customer satisfaction proposal (CSP) and that if I wish to fix the brakes/actuator issue it would be an out of pocket cost of a few thousand dollars. This is unacceptable and action needs to be taken immediately to recall and rectify this before innocent lives are lost due to brake failure.

Driving when I had to stop because of traffic light. Almost ran into a car because my brakes did not function correctly. ABS light and brake lights in dashboard came on. Pulled over. Called Tow truck. Had it towed to dealer. Brake Booster and master cylinder were replaced.

Own a 2010 prius w 110k miles on it and now hearing brake booster buzzing every minute when car is on when im sure its not suppose to be going off that frequently. And of course I missed the recall date.

The brake booster assembly and pump failed in my Prius. This causes the brakes to barely function. It disables both ABS and traction control. I nearly ended up running a red light and getting into a major collision with my three children in the car. The ABS, traction control, and BRAKE lights are all illuminated. Toyota advised they are aware this is a common failure but refuse to fix it. A dealership inspected it to confirm the flaw. Toyota will not fix it so I am forced to drive this vehicle with barely functioning brakes with my 3 children in the car still as I have no choice.

Brake booster actuator internal leak. Toyota refuses to cover the repair for the known defective and previously recalled part. See recall "D0H" and "customer support" campaign "ZJB" from Toyota. These are critical braking parts that control ABS, traction control, stability control, front/rear brake bias, regenerative braking and brake pedal feel and pressure. Loss of braking and all previously mentioned safety features occurs when the car sets the error codes, disabling and crippling the braking system. Longer stopping distances and much less responsive brake pedal is immediate. This part costs $700 from the dealer and they want over 2000 to fix the car due to the known defective, recalled part. This affects most Toyota hybrids of this era. The Prius is especially important to get recalled IMMEDIATELY, due to this being a common taxi and rideshare car, carrying multiple lives and heavier loads, in more severe operating conditions. Please look into this!! Toyota corporate has been called and they refuse to help or acknowledge the problem.

Brake, ABS and traction control warning lights went on when I was driving. I was able to brake but it was not functioning at 100%. The local mechanic was able to scan the code to get the C1391: Abnormal Leak of ACC PRESS error. The warning lights remain when I drive or parked. I no longer feel safe driving my vehicle. I plan to take my car to the Toyota dealer for further diagnosis and repair. I was informed that this is a very costly repair.

My brakes are failing. The brake booster leaks. The stopping distance is greater. All the warning lights are on on the dash. Error code C1391 on the unit. Two dealers would not repair it under warranty or recall. They gave me a price of $2600-$2800.The situation still exists. The car has had the engine replaced out of warranty but by the dealer but the brakes were not replaced as a preventive measure.

Brakes became soft the stopping distance grew.All my dash warning signs lit up. Why was my car to repaired in warranty or recalled when the problem was a manufacturer error? Toyota can't pick and chose which cars they will fix when they all have the same problem. I am attaching a 'Customer Support Program' sample and my car falls under the Primary Coverage section. My car was diagnosed at a dealership on 5/14/2021. But not fixed under warranty or recall. Toyota has recall on brakes for many of the newer cars too. Same issue.

I was driving my car with my daughter and was about to stop at the intersection and at that moment I realized that the car was not slowing down. ABS, Brake, and Traction control lights up on the dashboard. I was very scared and pressed the brake to the end and only then the car was able to stop. Further I found out that this is a very common problem for this model, but Toyota does not recognize this.

After descending a long mountain highway in our 2010 Toyota Prius and coming to a stop at the bottom the brake pedal travel suddenly increased, brake effectiveness decreased, and many dashboard lights suddenly came on including the brake system warning light and stability control system light. The next morning the dealer diagnosed a brake booster failure and prescribed replacement of the brake booster and master cylinder. Since this was a safety issue we had them do the work at a total cost to us of $3,363.93. They covered a rental car for us for only part of the repair period, which took 2 weeks.

The contact owns a 2010 Toyota Prius. The contact stated while driving 40 MPH, the ABS and traction control warning lights illuminated along with several unknown warning lights. The contact also stated that the brake pedal would depress to the floorboard while in operation. The contact took the vehicle to an independent mechanic who diagnosed the vehicle with a defective brake booster pump and ABS control module. The manufacturer was notified of the failure and informed the contact that there were no recalls or warranties on the VIN. The dealer was also notified and confirmed that the vehicle was not included in NHTSA Campaign Number: 10V039000 (Service Brakes, Air) which he linked to the failure. The vehicle was not repaired. The failure mileage was 130,000.

While driving, left dash-light cluster and ABS triangle illuminated in-traffic with no visual pre-warning or audible alarm. Pedal pressed full force to bring car to stop and not plow vehicle in-front. Owners manual & internet suggests ABS & booster pump failure. Call to mechanic also suggests booster pump and ABS module as possible basis for trouble lights. Arranging transport to Prius specialty shop (not dealer) for further diagnose. No collision no injuries. Note. Full service brake rotors & pads completed 27-days earlier and only 671-miles driven since costing $946 paid. No issues discovered by reputable Prius shop as to noise, leak or visual other. R.

About 3 weeks ago, I was driving down PCH around Manhattan beach , California. Suddenly the dashboard lit up like a Christmas tree , the ABS light , Brake light , pre-collision system light and a yellow triangle with an exclamation point in the middle all turned on at the same time , and a loud beeping alarm went off inside the car that was deafening and most importantly the brake pedal turned very hard I had to stand up on it just to slow down to brake and my braking distance tripled . I almost hit the car in front of me . I had this terrible feeling that the car isn’t safe to drive . It feels like the brakes failed. Luckily there was an autozone nearby so I pulled in their parking lot and borrowed a code scanner . C1252 , C1253, C1319 was the codes that showed up all indicating that the abs system failed and the results is recommending to replace the brake booster pump and the abs module. There’s also a leak of some kind within the abs system. I brought it to an independent auto shop near my residence and the shop told me that the and power brake booster and the abs module needs to be replaced . The repair will cost $2.000 to get fixed in which I can not afford. I was able to seek help from my siblings and was able to come up with $1200 . So I’d figured the shop owner might be able to let me pay half first and half in 2 weeks or so when the car is fixed. But when they replaced the 2 parts with brand new ones ..yhe ECU isn’t communicating with the ABS module . The shop suggested that we bring the car to a Toyota dealership to get it diagnosed to figure out why the abs system is still faulty even when the abs power brake booster and abs module were replaced with new ones . Toyota dealership said they will charge $795 just to diagnose it . I almost passed out in shock.. I haven’t worked since the brakes failed on my car and I can’t afford to pay for the repair . Please help.

while driving on 01/31/2022, I noticed several warning lights came on suddenly on the dash and heard intermittent beefing noise while driving. I took my car to the dealership and they found M R&R brake booster and booster pump needs to be replaced and they informed me that recall warranty time of that equipment has expired and I paid for it to be replaced costing me $3539.76. Toyota motor company told me that they are not responsible to repair or replace it.

ABS and traction lights on ABS system not working was informed it is the break booster and ABS pump same as recall that ended in 2021 , I was never informed of recall and have found many other owners were not informed. At the cost of cars today many can’t afford to buy new and this is a serious Safty issue Toyota should take responsibility for the repairs

I have been experiencing issues with my brakes for last few years. I had received a letter from Toyota in 2019 stating that my car has faulty brake system and Toyota will repair the issue by replacing faulty brake components free of charge. However local Toyota dealer refused to complete the repair multiple times. First they suggested that they have not received any letter from Toyota. Then they said that they were busy and I should come back later. They also told me to put the car on Park gear or re-start the car to get rid of ABS lights. Also they stated that repair can be done anytime later until my car reach to 150,000 miles. Last week I went back to Toyota dealer again. This time they told me I should have repaired the car through extended warranty. I was also told that their former service staff must have misguided me. I contacted Toyota Customer Care and complained about this issue. They confirmed that they can see in their system that I had visited the dealer for brake issue back in 2019 and repair was not done. However they suggested that Toyota will not provide any help now. Because issue is between me and the dealer.

While driving, without stepping on the brakes, a number of warning lights came on; including brakes, ABS warning, and stability control. When attempting to stop the car the brake pedal went down a long way before the brakes engaged. I then limped home. After deciding what to do I called a Toyota dealer, made an appointment, then limped to a dealership for evaluation and service. While on the way to the dealership, the brakes were erratic; sometimes the brakes and pedal acted normally and other times it would go down a long way before braking. The warning lights stayed on.

The braking system malfunctioned resulting in loss of braking ability and response along with various warning lights including ABS, Brake, and Traction Control. The vehicle produced a C1391 Diagnostic Trouble Code (DTC) indicating "abnormal leak of accumulator pressure." After taking the vehicle to a local Toyota dealer, I discovered there was a voluntary customer support program to replace what was known to be defective brake booster parts that expired in 2020. I previously did not receive any notification about the issue and am now told it will cost thousands of dollars to replace the brake booster parts known to be defective. I now have a vehicle that is unsafe to drive unless I spend an exorbitant amount of money to replace the aforementioned parts.

The contact owns a 2010 Toyota Prius. The contact stated while driving approximately 25 MPH, the ABS warning light illuminated. The contact stated that the braking system was not normal however, the vehicle was drivable. The contact drove the vehicle to an independent mechanic who provided the contact with a code for an ABS fault. The vehicle was not repaired. The contact notified the manufacturer of the failure. The approximate failure mileage was 136,000.

The brakes ABS stopped working. It is a known issue and is effecting many older Prius drivers.

The contact owns a 2010 Toyota Prius. The contact stated while driver was driving 65 MPH and depressing the brake pedal, multiple times, the vehicle brakes failed to stop the vehicle within a reasonable time. The contact stated there were several unknown warning lights illuminated simultaneously. The driver was able to slow the vehicle using the parking brake and driving onto the grass on the side of the road. The driver was able to continue driving to the local dealer. The vehicle was diagnosed and the contact was informed that the braking system needed to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was 179,747.

Brake booster failed. Brake Actuator failed. ABS,BRAKE and TRACTION control light is on.

I purchased my car in January 2010 within that first year I noticed that randomly if I hit a bump in the road and I would apply my brakes my car would do a wired skid and I couldn’t break properly. This has continued the entire time I’ve owned my car. Last month I was driving down the highway and ABS! Red brake light and ABS warning light all illuminated. As I was exiting the highway and applying the break I noticed my brakes were very spongy taking considerably more effort to stop. I started noticing a few months ago my breaks took considerably more effort stop and breaks felt spongier. The day my warning lights lit up a mechanic stated a code of C1391 was detected. Indicating break booster problems. NHTSA issued a recall Rep 13v235000 which is Break Booster my car was manufactured 10/09 so I understood my car was part of this recall but Toyota claims that is not a recall but a customer support program which has expired 2 years ago. I’m the original owner w/ 69,000 miles. Clearly my vehicle has and continues to have break issues so why is Toyota shirking responsibility and endangering me and other drivers allowing a car w/ breaking issues to not be properly repaired under the recall

Brake booster/ Brake Actuator problems

I believe Brake Actuator seems to be malfunctioning. Noises come from the location of the Brake Actuator when I am lightly braking at low speeds. I am getting Antilock Braking System code "C1256" reading "ACCumulator Low Pressure". There are a similar recalls related to my issue. Recall number: 10V039000 and Recall number: 13V235000

A known defect was briefly recalled, then sunsetted. My brake attenuator has failed, as has been the case for many others on this model. Toyota has acknowledged the defect, but no longer supports it.

Normal braking pressure failed to stop the vehicle requiring the driver to apply very heavy pressure to stop the vehicle and avoid a rear end collision. Multiple dash lights appeared and the vehicle was towed to a Toyota dealer. The dealer confirmed codes C1252 and C1256 exist and recommended that the brake booster pump assembly be replaced. An August 6, 2018 Toyota Service Bulletin (T-SB-0079-18) recognized this problem. Toyota sent Customer Support Program Notification ZJB noting that "Toyota has received reports about certain internal malfunctions of brake booster assemblies in some of the subject vehicles. In these reports, customers have noted various brake system related warning lamps illuminated." Toyota noted that, "This is not a recall." Toyota suggests that certain warning lights may illuminate but does not warn drivers that normal braking may cease and that the vehicle can be dangerously difficult to stop.

ABS brake light on. Just purchased this vehicle and found Toyota knows of a defect in the master brake cylinder that causes it to leak. Toyota was repairing this problem free of charge till 2019. This vehicle has never had the repair. I am told brakes may go from power brakes to non power brakes while driving. We are not driving till it gets fixed because of safety problem with brakes.

There is a known problem with 2010-2015 Toyota Prius brake actuator assembly and also the brake booster pump assembly. A leak develops and cannot hold proper brake pressure which will lead to catastrophic failure of the system and a life or death brake failure. Toyota has acknowledged the problem and issued a recall only covering 150,000 miles or 10 years from date of first use. This recall should be extended to all affected vehicles for the LIFETIME of the vehicle given that it is a known manufacturing defect affecting life and limb and that repair costs average over $3000.

Brake booster/ brake pump / accumulator sudden failure BELIEVED TO BE CAUSED BY THE SENSOR WARNING SYSTEM ? THAT ABS LIGHT ASSOOCIATED WITH CONSTANT BEEPING NOISE, 10 SECONDS LATER LOSE OF BRAKE POWER. factory trick to get brake service, at large for this repair costs 3800 per dealership toyota carlsbads. Manipulative recall disallowed me on 3 occasions unable to get part replaced by Toyota. When contacting corporate the did not demand me to get fixed and not drive NY car, again getting my car to tge service station experienced noise occurring then sudden outage of brake power reduced to nothing. A similar youtube video and my personal video explain sudden loss of brake power or pressure... after lights go on. And immediately return to normal after lights get reset. Sensor failure leading to brake failure, really scary and obviously a big problem TOYOT SHOULD STILL BE RESPONSIBLE FOR. CONSUMER SERVICE PROGRAM BY TOYOTA FOR THIS BRALE BOOSTER ISSUE STOPPED FOR SOME REASON IN 2019 ALSO. 150K BS RULE. MERCEDES BENZ HAS TAKEN THE RIGHT ACTION TO FIXING BRAKE BOOSTER ISSUES.

The Traction control, ABS, and Brake light all came on simultaneously. It was random with no trigger. The brakes feel spongy, and will not regenerate to charge the hybrid system.

The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds, the brake pedal was depressed however, the vehicle failed to respond as needed; causing the stopping distance to be extended. The contact stated that the ABS, brakes, and traction control warning lights were illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the ABS system and brake booster needed to be replaced. The local dealer was contacted and the contact was informed that NHTSA Campaign Number: 10V039000 (Service Brakes, Air) had expired. The manufacturer was notified of the failure but provided no assistance. The approximate failure mileage was 220,000.

My brakes have been making hissing noises whenever I press on the brake pedal for the past year. While driving on the freeway 300 miles from my home, numerous lights on my dashboard came on including brake, VSC, PCS, ABS, Triangle and "CHECK PCS SYSTEM" warning message. The brake also makes pumping noise every 4 seconds. The vehicle has no regenerative braking. The brake pedal is mushy and doesn't slow the car down until the pedal is fully depressed. I contacted Toyota and was told that there was a Customer Support Program ZJB that covers 2010-2015 Prius Vehicles for Brake Booster and Brake Booster Pump Assemblies. However, that program only covers 10 yrs 150 miles. My Prius has 110k miles but it's 21 months passed the program coverage. The car is dangerous to drive and Toyota will not honor the recall. I am stuck with a car with no brakes.

On March 25, 2022, I was driving my 2010 Toyota Prius, approx. 209,000 miles. When I had parked my vehicle, and turned my A/C on, my vehicle started to make this annoying beeping noise non-stop and all of the light on the dashboard had lit up. My brake lights, ABS, and the slip indicator all came on. When I went to drive my vehicle all of sudden my brakes did not respond. I had to force break and push down on the brakes very hard, to the point where I'm flooring the brakes. I checked with Toyota to see if there was a recall on my vehicle, and they told me that there were no recalls. When I did my research on 2010 Toyota Prius, I found that this is a common issue that the brake actuator and brake booster pumps are faulty on these vehicles. I did not receive a recall notice for this vehicle. Currently, my vehicle is not drivable and not safe to drive. For this to happen out of nowhere with no warning is unacceptable.

As nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash.

A number of things have failed on this car. 1. The hybrid battery pack system shut down and warned that I needed to see a mechanic. My mechanic diagnosed that the hybrid invert was defective and causing the battery pack to fail. 2. When braking at both low and high speeds, the car increasingly struggles to come to a stop. When applying foot pressure, you can hear the pump winding - this occurs while at rest as well as when trying to slow the car down. There are times when applying the brake that the floor pedal will lock and cause the car to skid while barely reducing the speed of the car. I have had multiple near accident incidences as a result and put myself and others at risk. 3. The car ferociously vibrates every morning - discovered that the head gasket has failed prematurely and due to the car overcompensating for the failing hybrid battery that is being impacted by the failing hybrid inverter. All problems have been reproduced and diagnosed at independent service centers. Multiple codes, warning lights and messages have alerted me to engine and battery issues - all of which appeared after the various issues and failures.

2010 Prius Brake, ABS, Traction Control Lights On/Off with no codes I bought new car and running smooth so far. I got this lights 2 months back and off for sometime and came back on and off and now quite often coming back and forth, 106K miles had the ABS, Traction Control and Brake light all come on at once same time and off same time and back and forth. No codes and no flashing but this is very critical as all related to brake systems failures may leads to crash because we don't know when this lights on and off and no codes to fix this issue.

For the past 2 weeks my prius has been acting very strange. When driving I have a hard time coming to a stop when pushing the brake and I realize that that the ABS light is on as well the brake light is on. Sometimes it will work fine with the lights off, and somtimes it messes up again. I heard that it could be a brake booster or module. I believe it was already recalled a few years ago, but seeing a lot more people complain about recently is a bit concerning. The part that was replaced, it should work for many years not less than 10. Its a huge risk for myself and others. I didn't realize what was happening until I needed to stop fast. This needs to be fixed fast and the right way this time before somebody dies

Brake system fails under normal driving conditions. Dealership diagnostics confirmed this falls under the Customer Support Program ZJB. This program expired in 2020 and Toyota customer care is unwilling to fix or reimburse for the $2200 expense associated with the defective brake booster and brake booster pump assembly. The Toyota case number is #220318001387.

Brake warning lights, traction control, and ABS warning lights all illuminated on the dash. Taken to the dealership and was told brake failure due to actuator or brake boost. Upon further research, it looks like this is a known issue with the Prius but Toyota is only providing service/repair to certain vehicles who already show brake failure instead of issuing a recall for all potentially affected vehicles.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the vehicle started making a beeping noise. The contact stated that an unknown warning light was illuminated. The contact pulled into an apartment complex and while depressing the brake pedal the failed to respond. After driving over several speed bumps and using extra energy to depress the brake pedal the vehicle responded and slowed to a stop. The vehicle was towed to the dealer where it remained. The contact stated the dealer informed her that the brake master cylinder and brake booster pump needed to be replaced. After researching the cause of the failure, the contact referenced NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included. The manufacturer was contacted and informed of the failure. The contact was then informed that the vehicle warranty had expired. The approximate failure mileage was 180,000.

The contact owns a 2010 Toyota Prius. The contact stated while exiting the highway and getting into the right lane at 60 MPH, the ABS warning light, brake light, and the traction control warning light illuminated and the vehicle lost braking functionality. The contact depressed the brake pedal with added force to get the vehicle to slow enough that he was able to get off of the highway ramp and pull over. The contact turned off and restarted the vehicle; however, the warning lights were still illuminated. The contact stated that extra force was needed to stop the vehicle. The contact drove the vehicle to his residence. The contact has not taken the vehicle to a local dealer. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 182,000.

The Brake booster and master cylinder failed causing the braking system to fail while driving

My prius appears to have the same problem that an excessive number of other 2010 priuses have with it's regenerative braking. This is a common and well known issue among these cars. Despite the fact that I am at 132k miles, under the 150k limit for the extended warranty, I am going to be stuck spending thousands and thousands of dollars to get my vehicle fixed because it is about 2 years past the 10 year limit.

2010 TOYOTA PRIUS. CONSUMER WRITES IN REGRDS TO DEFECTIVE ABS SYSTEM. THE CONSUMER STATED THE DEALER ADVISED THE BRAKE ACCUMULATOR. THE CONSUMER WAS INFORMED ABOUT A RECALL BUT, IT HAD BEEN DISCONTINUED. THE BRAKE BOOSTER PUMP ASSEMBLY WAS REPLACED AT THE OWNER'S EXPENSE.

While driving, my traction lights, ABS light, and Brake light came on the dash with no noises or other messages. I noticed my brakes took significantly more distance to stop and then stopped working altogether. I had to use my emergency brake to get stopped safely.

The contact owns a 2010 Toyota Prius. The contact stated that the braking system warning light was illuminated. The vehicle was taken to the dealer and diagnosed with a brake fluid leak in the brake master cylinder. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and informed the contact that the extended warranty had expired. The failure mileage was approximately 81,000.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS, traction control, and parking brake warning lights illuminated. Additionally, the brake pedal was difficult to depress. The vehicle was taken to the dealer and diagnosed with brake booster pump assembly failure. The brake booster pump assembly needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The contact related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes) however, the VIN was not included in the recall. The failure mileage was approximately 88,500.

The brake assembly is noisy while stopped at lights. The brake pedal continues slowly downward when pressed as if there is a leak in the brake master cylinder. Toyota has issued a warranty extension for a problem of fluid leaking in the brake booster, but did not notify me. Toyota's code for the warranty extension is Customer Support Program ZJB. Two local dealerships have refused to perform the repair because the warranty extension expired before I became aware of the issue.

2010 toyota prius brake booster failure. according to multiple resources online, there have been known issues with this part from Toyota across multiple models. After recalling only a small portion of vehicles due to this failure, complaints have been filed with nhtsa to address toyota's lack of corrective action regarding the vast amount of vehicles utilizing this technology. this is a dangerous defect that caused my brakes to malfunction during a cross-country trip. my brake and ABS lights suddenly came on, and i could tell my prius handled differently. the brake pedal became hard to depress and stop time increased drastically. i am having a mechanic diagnose and repair this issue costing no less than $1200 in austin, TX. i would like to make a complaint to toyota for not recalling all the models with this issue and instead choosing to recall a minute fraction of potentially defective vehicles.

We have a 2010 Prius Purchased March 2010. Toyota issued a "Customer Support Program" (free extended warranty) for the brake booster and brakebooster pump assemblies in 2019. The Primary Coverage was offered until 11-30-19 regardless of milage. After that the secondary coverage applied for 10 years or up to 150,000 miles. The information mailed to us states; "If you have not experienced the condition described above, there is no action necessary at this time." We did not experience any brake problems until 11-10-21, when the dash display lit up with the BRAKE LITE, ABS LITE, SLIP INDICATOR LITE, AND THE ! LITE, ALL CAME ON AT THE SAME TIME. ALSO THE BRAKE PEDDLE BECAME SPONGY AND AT TIMES VERY HARD TO DEPRESS. We had our Toyota dealer run a diagnostic scan of the vehicle and they determined the brake booster and brakebooster pump were defected. The car has 70,000 miles on it at this time, and we have owned the car for 10 years and 8 months. Toyota will not honor this Customer Support Program since we are 8 months beyond the expiration date. There was a RECALL number 13V235000 issued 06-05-13 for the same exact problem, with NO EXPIRATION DATE. However, Toyota says it does not apply to our car. This problem causes the power brakes to not work as power, only manual brakes (Hard to Push). They also become very soft and not responsive if the engine has not run since the last time the brakes were pushed. THIS IS A DANGEROUS SAFETY ISSUE! ! ! My question is, the problem was a big enough to have Toyota issue this 10 year "Customer Support Program" to prevent a hazardous situation from being on the road for 10 years, why is it not hazardous NOW 8 months later? We welcome any help you can provide.

I have a 2010 Toyota Prius. The ABS pump unit broke down while driving on the road. Suddenly the breaks were not functioning correctly. Breaks got squeeze. Apparently it's a common issue and Toyota had a program around it to fix it till Jan 2021. But I couldn't go fix it before coz the lights didn't show up. Now in Oct 2021 it's broken and is not covered. I don't know how a company gets to call such a safety issue as option and not a recall and get away with it. The vehicle has already been identified as having a bad part. How come the company does own up to it considering it's an important part of the breaking system.

while driving traction, abs and brake light came on. braking feels forced by driver.

The contact owns 2010 Toyota Prius. The contact stated while driving 72 MPH, she noticed several unknown warning lights illuminated on the vehicle and a beeping sound coming from the vehicle. The contact noticed that whenever the beeping sound was present, it was very difficult to depress the brake pedal to slow the vehicle. The contact had to depress on the brake pedal all the way to the floor for the vehicle to slow down and for the contact to pull over to the side of the road. The contact waited for a minute before restarting the vehicle and continued to drive a short distance before the failure recurred. The contact was able to restart and slowly drive the vehicle back to the residence. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the ABS pump needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 140,000.

The brakes, ABS, and traction light came on car but it does not stay on. Took it to the dealership and the advisor said it would be $2,500. If this gas been a recall in the past then it should still be a recall. I am extremely disappointed in Toyota as a whole to bail out on something that is as crucial as the safety of brake failure.

The Brake Booster assembly for nearly all 2010 Toyota Prius has innate failure over time. It is a faulty, known-issue part. Toyota offered some limited-time warranty extension fixes instead of a full recall. My Toyota dealership informed my that my part needs the fix, as would be expected, but that I am not within the limited warranty. As this is a safety issue and the part has given out, I am stuck. I contacted Toyota directly and via email as well and they refused to do anything while acknowledging the part was their fault. They were very snooty about the fact that a full recall had not happened yet, and gleeful to deny me service.

The contact owns a 2010 Toyota Prius. The contact stated that while driving, the brake lights, ABS, and check engine warning lights illuminated. There was an abnormal noise detected. The vehicle was taken to the local dealer and diagnosed that the brake booster assembly needed to be replaced. Additionally, the contact was informed that the vehicle was not safe to drive. The manufacturer was notified of the failure and referred the contact to NHTSA. The failure mileage was approximately 115,000. The VIN was not available.

Hazards lights came on and would not go off, with increased speed hazards flashed faster. Toyota stated that ABS actuator and relay needed to be replaced.

Parked with car running. Car started beeping (beep beep beep) incessantly. Turned off. When I turned 2010 Prius back on, the beeping came back. Brakes DID NOT WORK. Dash error said "CHECK PCS SYSTEM" and many warning lights were on. Pressing brakes didn't stop vehicle.

As many other 2010 Prius drivers have experienced, my brake actuator has failed. This has resulted in loss of braking and potential harm.

code C1391 master cylinder internal leak

ABS pump failed, all the lights came on the dash for brake, and brakes stop working properly it still drives but unsafe to do so, Toyota says it’s common problem and they want $3000 to replace it

ABS brake booster slow leak. There are many reporting the same problem on YouTube as a $3000 repair.

Brake assist has failed. Appears to be master cylinder assembly and/or pump? Brake related error lights and safety systems disabled. Very difficult to drive vehicle without power brakes. Car only has 106k miles on it, and too old for enhanced warranty coverage (acknowledged problem). This is not some 20 year old car with 300k miles on it.

First problem the light on my dashboard appeared. My braking is starting to not work properly. When i press the pedal it feels soft, and the brakes are not bitting well. Next thing my abs is not working, that i skid multiple times, and that cause me a few times to almost get into an accident. I had few fender bender issues, but no major damage collision. I end up paying for the repairs of my car, and have the receipt to prove it. Also before having all these issues, with the regenerative braking itself, if i happen to hit a pothole, even thou i’m pressing the brake pedals. It causes the car to accelerate. This only happens during traffic stops that i’m already pressing the brakes, but for some reason if i hit a pothole, like i mentioned above. That car accelerates, and thus cause me to almost hit the car in front of me. I was aware of this issue, so to compensate, i pressed the brake pedals harder whenever this incidents happen.

My 2010 Prius is experiencing brake booster failure. Brake assist appears to be lost. Feels unsafe to drive since braking distance feels longer. Unsure if stability control is working. Hybrid battery not recharging from braking. Warning lamps include: 1) Brake System Warning Light (red indicator); 2) Brake System Warning Light (yellow indicator); 3) ABS Warning Light; and 4) Electronic Stability Control Active Warning Light. OBD-II trouble code: C1391 (abnormal leak in accumulator). Spoke with representative Tracy at Toyota Customer Experience Center (888-270-9371) on 7/30/2021 (Case #210730000924) and Randall at Toyota Customer Experience Center on 8/3/2021 about repair through Toyota. Both representatives acknowledged that Toyota was aware of the brake booster failure from owners. Randall acknowledged that many owners have complained to Toyota about brake booster failure and that is it commonly reported to Toyota, hence Toyota issued a Toyota Customer Support Program Notification ZJB. However, I am told that coverage for my Prius under Notification ZJB has expired, that there is not a recall for the defective parts, and that Toyota will not assist with fixing this problem for my car. I believe this problem is a safety issue and that Toyota needs to issue a recall as soon as possible to remedy this known defect.

MULTIPLE WARNING LIGHTS CAME ON SUDDENLY WHEN I WAS DRIVING THE PRIUS LAST MONTH; 'ABS', 'BRAKE', AND 'TRACTION CONTROL' WARNING LIGHTS ALL CAME ON SIMULTANEOUSLY. THE BRAKING FUNCTION WAS NOT NORMAL. HAD TO DEPRESS THE BRAKE PEDAL A LOT MORE FOR THE BRAKE TO BE APPLIED. ALSO BATTERY IS NO LONGER RECHARGING ON APPLYING BRAKES. TOOK IT TO THE LOCAL TOYOTA DEALER (FRED ANDERSON, RALEIGH, NC). THE ESTIMATE FOR REPAIR IS $4045. THE CAR IS 2010 MODEL (11 YRS) AND HAS 106000 MILES. THIS IS KNOWN PROBLEM AND IN MY OPINION AND DESIGN FLAW AND TOYOTA NEEDS TO FIX THIS. PLEASE HELP.

All my lights are on traction, brake, ABS!

Brake light, ABS light, and traction control light all illuminated on dashboard. Took the vehicle to Toyota dealership and they determined I needed to replace the brake booster/accumulator and pump assembly, cost was $3,000.00. Looking into this issue further it is an extremely common issue and should be a recall item.

After buying the car from Liquidation Station (used car dealer) the day after we bought the (2010 Prius Hybrid) the breaks went completely out. My daughter and grandchild were in the car and she almost crashed in to on coming traffic putting them in extreme danger of being killed. We had the car towed to Caldwell Toyota in Conway AR. and they said the break booster had failed and that they would not cover the cost of the repairs even though there are several complaints of break failure and several recalls for this car.

I was driving when the car started to beep constantly. I tried to turn on a road to check it out and realized I had no brakes. I passed the road I was trying to turn on and had to coast to a stop down the road. If this had happened while coming to a red light, there is no way I would have been able to avoid a wreck. I did some research and found that they extended the warranty on the brake booster and assembly pump. The thing is I had taken the car in because the abs, brakes, and traction control lights came on last year. They acted like they had no clue what was wrong and just unplugged the battery and hooked it back up to make sure the lights went off. The lights were off for less than a mile and when I called back they acted clueless and said for $200 out of pocket they can do more extensive testing but said they saw nothing wrong and that the car was driving normally. How does Toyota have a major problem that they extend the warranty and the Toyota dealership knows nothing about it and can’t give me answers when I have the exact issues the extended warranty is supposed to cover? I could have been seriously injured and hurt someone else and Toyota doesn’t care. Their representative told me that they had done enough and it was on me to fix the problem as now I was no longer covered under their extended warranty. This is a major safety issue and needs to be a recall before someone gets seriously hurt. Toyota knows there is a problem but refuses to hurt their bottom line to protect the consumers. This just happened yesterday and I have not done anything to the car at this time.

Actuator and brake cylinder have gone. ABS, traction, and brake lights all have gone on. This is a very common issue with this car, and I am expected to pay $3,000 for this fix.

The brakes failed while driving. The traction, ABS and brake light all came on, on the dashboard and the brakes were working at 10% or less. I had to use the engine braking mode to stop the car. I took it to a technician and this is a known issue that Toyota is ignoring.

ABS light and brake light comes on and goes away on my toyota prius 2010

I have a 2010 Toyota Prius. I was driving home on I-80 and when I was getting down on the slope of the Sacramento river bridge, three lights suddenly popped on the dashboard - ABS light, Brake light and Traction control light. Following this, I lost efficient control on the brakes and I had to push really hard on the brake pad to even slow the car down. If I had to stop suddenly, it would have definitely resulted in a serious crash. Because the brakes stopped working as they are supposed to, I turned on the blinkers, took the exit and tried to stop slowly. I was able to stop on the side of the road just before the red signal. I was just couple of miles from my home so I kept the blinkers on, and slowly drove through internal roads to my home. Later when I found out the code, it came as C1391 which is usually for failure of the brake booster assembly or the brake booster pump assembly or both. When I contacted my local Toyota dealership, they mentioned that the extended warranty for replacing these parts ended in November 2020 and because of that they asked me to take care of this >$3000 repair. I also contacted Toyota corporate to file a complaint and was told the same thing. This issue is a serious safety concern and Toyota should issue a recall and not an extended warranty. They should not be waiting for people to loose their lives before they issue a recall.

The contact owns a 2010 Toyota Prius. The contact stated that while driving approximately 30 mph, the automatic braking system failed and the brakes were making a strange sound and not responding as soon as the brake pedal was depressed. The ABS, brake, and stability control warning lights were illuminated. The vehicle was taken to the dealer and diagnosed with hydraulic brake booster pump failure. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure but informed the contact that the vehicle was over the extended warranty coverage. The failure mileage was 118,000.

While driving in the highway had several times hard situations. Yesterday and truck became in front in my lane while, I had brake fast the car started loosing control and ended up on the side of the road. Is like the brakes makes the car loose all the control in a bad situation instead of help to prevent accidents. Each time I go to Toyota I had mentioned this issue, but they say there's not recalls available. Sometimes I think I will die because of this.

Code 1391. just like many others Toyotas of this year

The contact owns a 2010 Toyota Prius. The contact stated while driving approximately 30 mph, while coming to a stop on wet pavement, the vehicle failed to stop and crashed into the vehicle ahead of him. The air bags failed to deploy. A police report was filed. There were no injuries sustained. The contact stated that whenever the roads were wet, excessive force on the brake pedal was needed to stop the vehicle. The vehicle was not taken to the dealer and was not diagnosed. The manufacturer was not made aware of the failure. The approximate failure mileage was 208,000.

THE TRACTION , ABS AND BRAKE LIGHT COMES ON AFTER DRIVING OVER A SMALL POTHOLE

REGENERATIVE BRAKES STOPPED WORKING WHILE DRIVING IN CLEAR CONDITIONS ON THE HIGHWAY AT 60MPH, ABS, TRACTION CONTROL, AND BRAKES LIGHTS ON DASH ILLUMINATED. ALMOST CRASHED AS BRAKE PEDAL NEEDED TO BE PRESSED REALLY HARD AND ALMOST TO THE FLOOR TO STOP THE CAR. KNOWN ISSUE AND DEALER REFUSES TO FIX THE PROBLEM

I WAS DRIVING AND THREE LIGHTS CAME OUT: ABS, BRAKE AND SLIP INDICATOR.

I BOUGHT THIS CAR BRAND NEW IN 2010. TOYOTA PRIUS HYBRID. TWO WEEKS AGO THE ABS LIGHT, EMERGENCY BRAKE LIGHT, AND TRACTION CONTROL LIGHTS ALL CAME ON AND WON'T GO OFF. DEALERSHIP SAYS I NEED $2000 WORTH OF WORK. BRAKE BOOSTER/MASTER CYLINDER, BRAKE BOOSTER PUMP ASSEMBLY, BRAKE ACTUATOR INTERNAL LEAK. BRAKES ACTING WEIRD. DEALERSHIP SAYS I DON'T NEED TO DRIVE CAR, JUST PAY $2000 WHICH I DON'T HAVE. THEY SAID TOYOTA EXTENDED THE WARRANTY TO DECEMBER 2020, WHICH JUST PAST. I NEVER GOT LETTER SAYING IT WAS A PROBLEM.

I WAS DRIVING AND PRESSED THE BRAKE PEDAL TO MAKE A TURN. AFTER COMPLETING THE TURN I NOTICED SEVERAL WARNING LIGHTS ILLUMINATED ON THE DASH BOARD INCLUDING BRAKE, ABS, AND TRACTION CONTROL. THE BRAKES WERE VERY MUSHY BUT WORKED ENOUGH TO GET THE VEHICLE TO A SHOP. THE SHOP ASSESSED THE VEHICLE WHICH DISPLAYED CODE C1391 AND SAID IT WAS BRAKE RELATED POSSIBLY ABS SYSTEM. THEY CLEARED THE CODE IN MY VEHICLE AND BRAKES WORKED NORMAL FOR A VERY SHORT TIME BEFORE THE SAME WARNING LIGHTS APPEARED AND BRAKES WENT MUSHY AND NOT WORKING PROPERLY. I THEN LOOKED UP POSSIBLE RECALLS OR ENHANCED WARRANTIES AND I CALLED TOYOTA CUSTOMER SERVICE AND WAS TOLD THERE IS NO RECALL OR EXTENDED/ENHANCED WARRANTY FOR ANY BRAKING ISSUE ON MY VEHICLE BASED ON THE VIN NUMBER. I TOOK THE VEHICLE TO MY LOCAL TOYOTA DEALER AND THEY CHARGED ME TO TEST FOR A CODE. THEY CAME UP WITH CODE C1391 AND STATE IN THEIR PAPERWORK THAT THE CAUSE IS "BRAKE BOOSTER INTERNAL FAILURE" AND RECOMMEND REPLACING THE BRAKE BOOSTER. THEIR PAPERWORK SHOWS REPLACEMENT OF A BRAKE PUMP AND BRAKE BOOSTER HAD AN EXTENDED WARRANTY BUT THAT IT EXPIRED 9/26/2020. THEREFORE THE DEALER WOULD NOT FIX MY CAR AT THE COST OF TOYOTA. MY VEHICLE HAS APPROXIMATELY 91,000 MILES AND OTHERS WITH HIGHER MILEAGE HAVE DOCUMENTED THAT TOYOTA HAS REPAIRED THIS KNOWN, WELL DOCUMENTED, EXPENSIVE (ABOUT $4,000) AND CONTINUED DANGEROUS BRAKING PROBLEM IN SEVERAL CASES. PER THE DEALERSHIP AND MY CONTACT WITH TOYOTA THEY ARE NOT WILLING TO REPAIR MY VEHICLE AT THEIR COST., WHICH AT THE TOYOTA DEALERSHIP IS ABOUT $4,000 PARTS AND LABOR. AN ADDITIONAL ISSUE IS TRUSTING TOYOTA SERVICE AND/OR PRIVATE MECHANICS THAT THEY WILL REPLACE THE PROBLEM PART(S) OR REPLACING ADDITIONAL PARTS MAKING THE REPAIR BILL HIGHER OR MAYBE NOT FIXING THE PROBLEM WHERE ADDITIONAL REPAIRS WILL BE REQUIRED BEFORE TOO LONG.

TRAVELING HOME FROM TAMPA TO ST. PETERSBURG ON INTERSTATE AT 70 MPH AND SUDDENLY BREAKS FAIL. BRAKE, ABS, AND TRACTION LIGHTS COME ON. PUSHED PEDAL TO THE FLOOR AND WAS ABLE TO GET ENOUGH BRAKING TO PULL OFF THE INTERSTATE AND INTO A GAS STATION AND INTO A PARKING SPOT SAFELY. NO WARNING-JUST IMMEDIATE FAILURE. MIRACLE NO ONE KILLED. READING MANY OTHER SIMILAR STORIES FOR YEAR. WHAT IS GOING ON THAT THIS HAS NOT BEEN RECALLED????

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE DRIVING 20 MPH, THE BRAKE PEDAL WAS DEPRESSED TO THE FLOORBOARD WHILE ATTEMPTING TO STOP THE VEHICLE. THERE WAS AN ABNORMAL SOUND COMING FROM THE VEHICLE. THERE WAS NO WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO TOYOTA OF TAMPA BAY (1101 E FLETCHER AVE, TAMPA, FL 33612: (813) 402-1323) ON SEVERAL OCCASIONS TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE ABS MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. THE MANUFACTURER WAS INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 152,000.

JUST PURCHASE THE CAR AND THEY R REFUSING TO FIX THE ABS KNOWN ISSUE UNDER THAT ABS RECALL

TOYOTA PRIUS 2010 STARTED EXPERIENCING BRAKING ISSUES IN JANUARY 17, 2020. CAR WAS TAKEN TO THE DEALER THREE TIMES WITH MISS DIAGNOSIS. IN MARCH DEALER DIAGNOSED ISSUE MOST LIKELY A BRAKE BOOSTER AND PUMP ASSEMBLY WHICH WAS A KNOWN ISSUE WITH 2010 PRIUS. TOYOTA IDENTIFIED THE ISSUE IN A PREVIOUS QUALITY CAMPAIGN BUT ONLY REPAIRED IF BRAKES FULLY FAILED. BRAKE FAILURE IS WHAT IT TOOK TO HAVE YOUR CAR REPAIRED?

ABS, TRACTION, AND BRAKE LIGHT STAY ON. IT IS THE ACTUATOR BRAKE AND THE COST TO FIX IS OVER $2000. I HAVE RESEARCHED THIS ISSUE WITH OTHER 2010 PRIUS' AND IT IS A COMMON ISSUE. THIS IS A DEFECT THAT TOYOTA REFUSES TO FIX EVEN THOUGH IT IS VERY COMMON AND PUTS MANY PEOPLE AT RISK.

I HAVE LOST ALL REGENERATIVE BRAKING. THE ABS, TRACTION CONTROL, AND SERVICE LIGHTS ARE ALL ILLUMINATED CONTINUALLY. IT HAS BECOME DIFFICULT TO STOP AND THE HYBRID BATTERY IS DEPLETING AT A RAPID RATE WITH VERY SLOW RECHARGING.

HELLO, I HAVE A PROBLEM WITH MY PRIUS 2010, I HAVE NOT IDEA WHAT HAPPENED WITH MY BRAKES WHEN I WAS DRIVING IN HIGHWAY 95 NORTH IN FLORIDA, MY BRAKES WAS HEAVY AND DIFFICULT TO PUCH, AFTER THAT PROBLEM NEVER MY CAR WAS NORMAL AGAIN .I HAVE ALL THATS LIGHT ON IN MY CAR RIGHT NOW. I AM SCARY DRIVE MY CAR WITH THIS PROBLEM. I SEE LOT UP INFORMATION OF OTHER OWNERS OF TOYOTA PRIUS 2010 AND 2011 WITH THE SAME PROBLEM BUT ANYBODY KNOT WHAT IS THE PROBLEM . MY LIGHT OF BRAKES ABS , STABILYTRAC AND OTHER SYMBOLS OF PRACAUTION IS ON IN THE SAMETIME. IS IMPORTANT FIX THIS PROBLEM . OUR HEAL AND OUR LIFE CAN NOT BE REPLACE FOR AN BRAKES PROBLEM OF THE CAR . I CALLED TOYOTA THIS WEEK FOR LET THEY KNOW THE INFORMATION ABOUT MY PROBLEM AND OTHER USERS IN INTERNET. THIS IS A BIG SECURITY PROBLEM . SOMEBODY NEED TAKE CARE THE RESPONSABILITY ABOUT THIS , THEY DID AN DIAGNOSTIC ABOUT OF THIS PROBLEM AND THEY KNOW THE PROBLEM BRAKES IN THIS MODEL PRIUS LONG TIME AGO . I WANT A SEE ANY RESULT ABOUT THIS SITUATION BECAUSE IS OUR LIFE . THIS CAN BE DANGEROUS THIS FOR OUR SAFETY ON ROAD FOR MILLON PEOPLES IN UNITED STATES OF AMERICA.

WENT OVER BUMP AT RAILROAD CROSSING AND ABS, BRAKE, SLIP WARNING LIGHTS CAME ON AND REGENERATIVE BRAKING STOPPED WORKING. CAR WAS HARDER TO STOP. TOOK TO DEALER AND CAR WAS DIAGNOSED WITH THIS WORK NEEDED: REPLACE BOOSTER AND BOOSTER PUMP ASSY AND REFLASH (FAILED BOOSTER, BOOSTER PUMP) FAIL $3,259.84 CAR IS BEYOND WARRANTY FIX DATES THOUGH ALL THESE CARS WERE RECALLED IN CANADA AND A CLASS ACTION SUIT IS ONGOING IN OHIO OVER THIS ISSUE. WHY WON'T THE NTSB FOLLOW CANADA'S LEAD AND GET THESE FAILING BRAKE SYSTEMS FIXED BEFORE SOMETHING SERIOUS HAPPENS?

MY CAR'S ABS, TRACTION, AND BRAKE LIGHTS ARE ON. I TOOK IT TO TWO SHOPS AND THEY BOTH SAID MY CAR WAS RECALLED AND TO HAVE THE DEALERSHIP FIX IT. THE RECALL IS ON THE BREAKS. THE BRAKE PEDAL IS ALSO NOT FULLY WORKING, THERE IS AN ABNORMAL LEAK OF BRAKE FLUID PRESSURE. BOTH AUTO SERVICE PLACES SAID TO DEMAND FOR THE DEALERSHIP TO TAKE CAR OF THIS BECAUSE THERE IS A CLASS ACTION LAWSUIT GOING ON FOR THIS CAR WITH THIS EXACT PROBLEM.

I WAS DRIVING DOWN THE HIGHWAY AND THE TRACTION CONTROL, ABS, AND BRAKE LIGHT ALL COME ON. I GO TO USE THE BRAKES AND THE PEDAL WAS A LOT FIRMER AND WAS HARDER TO PRESS. THE CAR MAKES A BUZZING NOISE I BELIEVE IT IS THE BRAKE ACCUMULATOR. I GO TO THE NEAREST PLACE TO GET THE CODES READ. IT CAME UP WITH C1391 AND I LOOK THAT CODE UP AND IT COMES UP WITH THAT CODE IS A COMMON ISSUE WITH THE PRIUS. I READ THAT IT COULD LEAD TO BRAKE FAILURE.

BRAKE BOOSTER FAILURE, LOSS PRESSURE AT BRAKE THE CAR, THE STABILITY CONTROL AND THE ABS DOESN'T WORK

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT DRIVING AT 15 MPH, THE BRAKES FAILED TO OPERATE AS NEEDED UPON DEPRESSION OF THE BRAKE PEDAL. THE CONTACT STATED THAT SEVERAL WARNING LIGHTS APPEARED ON THE INSTRUMENT PANEL INCLUDING THE ABS, TIRE PRESSURE, TRACTION CONTROL AND EMERGENCY BRAKE LIGHTS. THE CONTACT WAS ABLE TO DRIVE THE VEHICLE TO HALEY TOYOTA OF ROANOKE (1530 COURTLAND RD NE, ROANOKE, VA 24012) WHERE SHE WAS INFORMED THAT THERE WAS A CRACK IN THE BRAKE BOOSTER PUMP ASSEMBLY ACCUMULATOR, A DECREASE IN THE HYDRAULIC PRESSURE, AND A DEFECTIVE BRAKE MASTER CYLINDER. UPON INVESTIGATION, THE CONTACT LINKED THE FAILURE TO NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES) HOWEVER, THE VIN WAS NOT INCLUDED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 162,000.

I TRAVEL TO WORK ONE HOUR AWAY FROM HOME, ON HIGH SPEED HIGHWAY'S MY BREAK SYSTEM LIGHTS TURNED ON, TRACTION, ABS AND BREAK, BREAK PEDAL SINKS AND WILL NOT BREAK AND IS VERY DANGEROUS WHEN DRIVING HOME. I HOPE NO ONE GETS KILLED

TOYOTA BRAKE BOOSTER PUMP HAS FAILED DUE TO MANUFACTURING DEFECTS, WHICH AFFECTED THE STOPPING OF THE VEHICLE. TOYOTA HAS ISSUED RECALL FOR THIS PROBLEM BUT ONLY FOR LATEST MODELS (2019 AND LATER). I'VE CALLED TO TOYOTA AND THEY REFUSED TO ADDRESS THIS PROBLEM. I LOOKED UP ON INTERNET AND FOUND THIS IS A WIDE SPREAD PROBLEM EXPERIENCED BY MANY OWNERS OF PRIUSES. TOYOTA MUST ISSUE THE RECALL FOR ALL THE VEHICLES AFFECTED, NOT THE LATEST ONES ONLY.

I AM HAVING AN ISSUE WITH MY BRAKE ACTUATOR/BRAKE BOOSTER. THIS IS A KNOWN ISSUE AND TOYOTA IS REFUSING TO HELP WITH THE ISSUE. THE ABS, BRAKE, AND TRACTION CONTROL LIGHT ARE ON AND REGEN BRAKING IS NOT WORKING. THEY ARE SUPPOSED TO COVER THIS BASED ON BULLETIN ZJB BUT ABSOLUTELY REFUSE ANY HELP.

UPON STARTING THE CAR, THE ABS, BRAKE AND TRACTION CONTROL LIGHTS ALL CAME ON. CHECKED BRAKE FLUID AND IT WAS AT MAX LEVEL. TOOK TO DEALER AND SHOWED CODE 1391 WHICH SHOWED THE BRAKE BOOSTER AND BOOSTER PUMP ASSEMBLIES NEED REPLACING. IT'S A KNOWN PROBLEM WITH TOYOTA. A VOLUNTARY RECALL WAS ISSUED FOR OUR 2010, BUT MY SPECIFIC MODEL WASN'T INCLUDED AND RECALL EXPIRED IN 11/19 OR 150K MILES. I'M AT 150,992. THERE IS ACTIVE RECALL FOR SAME ISSUE FOR 2011-2015 MODELS. IT'S A KNOWN SAFETY ISSUE AND THEY REFUSE TO FIX IT. IT'S A $3K JOB TO REPAIR FOR A CAR THAT IS WORTH ABOUT DOUBLE THAT. WHEN THIS WARNING COMES UP, YOUR BRAKING SYSTEM IS NOT RELIABLE. HAD THIS HAPPENED WHILE DRIVING, AN ACCIDENT COULD HAVE OCCURRED. TOYOTA KNOWING THIS IS A SAFETY ISSUE NEEDS TO CORRECT IT ON ALL MODELS THAT SHOW THIS WARNING, NOT JUST SELECT MODELS.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DEPRESSING THE BRAKE PEDAL, THE BRAKE PEDAL WAS FIRM CAUSING THE BRAKING DISTANCE TO BE EXTENDED. THE VEHICLE WAS TAKEN TO TOYOTA OF LINCOLN PARK LOCATED AT 1561 N FREMONT ST, CHICAGO, IL 60642 WHO DIAGNOSED THE VEHICLE AND DETERMINED THAT THE BRAKE BOOSTER AND MASTER CYLINDER WERE DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 100,000. THE VIN WAS NOT AVAILABLE.

I WENT TO THE DEALER AS I WAS TOLD AFTER OPENING A CASE WITH TOYOTA,, HOWEVER THE SOLUTION WAS NOT RESOLVED TO MY SATISFACTION. BASICALLY. SAFETY PARTS WERE REPLACED FROM A RECALL ON 08/2013. A FEW YEARS LATER I GOT ANOTHER TOYOTA NOTIFICATION THAT IF I HAD THESE BRAKE BOOSTER RELATED FAILURES/LIGHTS TO BRING IT IN, I WOULD HAVE EVEN IF I HAD THE LIGHTS WITHOUT THE NOTIFICATION. THE OTHER DAY I HAD THE FAILURE RELATED TO THE DEFECTIVE PARTS INSTALLED ON 08/2013. SO SOMEWHERE BETWEEN 08/2013 AND WHEN TOYOTA NOTIFIED ME ABOUT THE LIGHTS OR THE STILL EXISTING DEFECT, THAT THERE WAS A DEFECT GOING TO HAPPEN BUT DID NOT KNOW WHEN AND TODAY I HAD THE FAILURE. I BELIEVED THAT SINCE I HAD THE ORIGINAL REPLACEMENT BRAKE SAFETY PARTS REPLACED THAT I WAS DRIVING A SAFE PRIUS. I FEEL THE SECOND REPAIR FOR THE SAME PARTS SHOULD BE COVERED SINCE WHEN THEY NOTIFIED ME THEY KNEW THERE WAS A DEFECT AND CHOSE NOT TO ABSORB THE COST OF THIS REMEDY.

I WAS DRIVING A NORMAL COMMUTE WHEN AT RANDOM, THE ABS, BRAKE, AND TRACTION LIGHT WENT ON. THE BRAKES SEEMED TO DEPRESS QUICKER AND FELT 'OFF'. I WAS THANKFULLY CLOSE ENOUGH TO HOME. THE BRAKE LEVELS WERE FINE, HOWEVER AFTER TAKING THE CAR INTO THE DEALER, I WAS NOTIFIED THAT THE BREAK BOOSTER FAILED AND NEEDED TO BE REPLACED. AFTER RESEARCH, IT APPEARS THAT THERE WAS A RECALL FOR THIS PART IN 2013, AS WELL AS A RECENT LEGAL SUIT SUGGESTING THAT TOYOTA DID NOT INCLUDE ALL VEHICLES THAT COULD BE AFFECTED BY THIS FAULTY PART (ISSUE TYPICALLY SHOWS UP AROUND 150K MILES). I HAVE A 2010 PRIUS ( INCLUDED IN THE SUIT) WITH JUST ABOVE 150K AND WAS NEVER NOTIFIED.

WHILE COMING HOME FROM WORK, MY WIFE NOTICED THE BRAKE, ABS, AND TRACTION CONTROL WARNING LIGHTS OF THE VEHICLE CAME ON WHILE ON THE FREEWAY; MY WIFE HAD TO IMMEDIATELY GET OFF THE FREEWAY SINCE SHE NOTICED THAT SLOWING DOWN THE VEHICLE REQUIRED MUCH MORE EFFORT THAN USUAL. SHE NEARLY HAD AN ACCIDENT GOING DOWN THE FREEWAY RAMP. WE HAVE SCHEDULED TO BRING THE CAR IN FOR A FIX SINCE THIS IS A HUGE SAFETY CONCERN TO US.

VEHICLE HAS APPROXIMATELY 120,000 MILES. WHILE DRIVING THROUGH TOWN OR ON THE HIGHWAY, OUR VEHICLE WILL INTERMITTENTLY LOSE REGENERATIVE BRAKING. DURING THESE INSTANCES, THE BRAKE PEDAL SOFTENS AND GREATER EFFORT MUST BE EXERTED TO SLOW AND STOP THE CAR. SOMETIMES MINUTES... AT OTHER TIMES THE NEXT DAY AFTER THE CAR HAS SAT IN THE GARAGE, THE INDICATOR LIGHTS WILL ALL TURN OFF AND REGENERATIVE BRAKING RESUMES NORMALLY. THIS CREATES A VERY UNSAFE SITUATION AS IT CAN BE UNPREDICTABLE HOW MUCH PRESSURE TO APPLY TO THE BRAKES. THIS IS BEEN NOTICED AT SLOW SPEEDS, HIGHWAY SPEEDS, IN TURNS, OR TRAVELING IN A STRAIGHT LINE. THE VEHICLE WAS DIAGNOSED AND DETERMINED TO HAVE A FAULTY BRAKE BOOSTER/ACTUATOR. THIS HAS CREATED AN UNSAFE AND UNRELIABLE SITUATION FOR TRANSPORTING MY FAMILY. WHAT IS QUITE CONCERNING IS THAT THIS OCCURRED WITH THE 2ND GENERATION PRIUS AND TOYOTA EXTENDED A HELPING HAND BY ISSUING A RECALL OR WARRANTY ENHANCEMENT. HOWEVER, MY VEHICLE WAS PRODUCED JUST MONTHS OUTSIDE OF THE 13V235000 RECALL WINDOW, YET EXPERIENCES THE SAME DANGEROUS DRIVING EXPERIENCE AS THOSE WHO WERE INCLUDED IN THE RECALL. TOYOTA NEEDS TO DO THE RIGHT THING AND THE SAFE THING BY RECALLING ADDITIONAL 3RD GENERATION PRIUS VEHICLES AND REPAIR OR REPLACE ALL FAULTY COMPONENTS BEFORE MORE CRASHES AND INJURIES OCCUR.

ABS ACTUATOR HAS A LEAK. IT IS A $1200 REPAIR. MY MECHANIC, WHO ONLY WORKS ON HYBRIDS, SAID THAT THIS HAS BEEN HAPPENING A LOT WITH MY YEAR PRIUS (AS WELL AS OTHER YEARS), BUT THE EXTENDED WARRANTY ONLY COVERS 2011 AND LATER.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE DRIVING AT LOW SPEEDS, SEVERAL UNKNOWN WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS TAKEN TO LOCAL DEALER HEADQUARTER TOYOTA LOCATED AT 5895 NW 167TH ST, HIALEAH, FL 33015, (786) 235-9734, WHERE IT WAS DIAGNOSED WITH NEEDING THE BRAKE BOOSTER TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT, CONTINUED TO EXPERIENCE THE FAILURE. THE MANUFACTURER HAD NOT BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS 80,117.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE DRIVING AT AN UNDISCLOSED SPEED, ANOTHER VEHICLE CUT IN FRONT OF THE VEHICLE. THE CONTACT QUICKLY DEPRESSED THE BRAKE PEDAL AND THE VEHICLE STARTED TO SKID. THE CONTACT LET UP OFF THE BRAKE PEDAL TO STRAIGHTEN THE VEHICLE AND STAY IN HER LANE. THE CONTACT STATED THAT THE ANTILOCK BRAKES FAILED. THE VEHICLE WAS NOT TAKEN TO A DEALER. THE CONTACT MENTIONED THAT SHE HAD TAKEN THE VEHICLE TO AN INDEPENDENT MECHANIC FOR AN OIL CHANGE BEFORE THE FAILURE AND WAS INFORMED THAT THE VEHICLE WAS UNDER RECALL. THE CONTACT CALLED FRED ANDERSON TOYOTA OF ASHEVILLE (777 BREVARD RD, ASHEVILLE, NC 28806) AND INFORMED THEM OF THE RECALL ON THE BRAKE BOOSTER PUMP ASSEMBLY. THE DEALER INFORMED THE CONTACT THAT THE VEHICLE WAS OVER THE MILEAGE FOR THE REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS APPROXIMATELY 197,000.

PREVIOUS RECALLS FOR A 2010 TOYOTA PRIUS (NHTSA CAMPAIGN NUMBER: 13V235000) AND A 2019 TOYOTA CUSTOMER SUPPORT PROGRAM (CSP ZJB) HAS ACKNOWLEDGED AN UNSAFE FAILURE MODE IN THE VEHICLE WHERE THE BRAKE BOOSTER ASSEMBLY FAILS DUE TO HIGH PRESSURE AND CAUSES THE AUTOMOBILE TO HAVE DIFFICULTY STOPPING. ON SEPTEMBER 4, 2020 WHILE DRIVING DOWN THE ROAD AT ROUGHLY 40 MPH, I EXPERIENCED INDICATION LIGHTS CONSISTENT WITH THE DESCRIPTIONS OUTLINED IN THE SAFETY RECALL AND TOYOTA SUPPORT PROGRAM. MY AUTOMOBILE ALSO HAD EXTREME DIFFICULTY COMING TO A STOP FROM 40 MPH AND I HAD TO UNSAFELY PULL TO THE SHOULDER OF THE ROAD AT SPEED TO AVOID COLLIDING WITH THE AUTOMOBILE IN FRONT OF ME. THE TOYOTA CSP ZJB DOES NOT COVER MY VEHICLE DUE TO TIME AND MILEAGE OF THE VEHICLE, BUT I FEEL THIS SAFETY CRITICAL SYSTEM SHOULD HAVE BEEN REPLACED PRIOR TO ME EXPERIENCING A FAILURE. TOYOTA SELECTIVELY ONLY REPLACED BRAKE BOOSTER ASSEMBLIES OUTLINED IN THE RECALL AND THE CSP, IF THE AUTOMOBILE WAS EXPERIENCE ISSUES. TOYOTA STOPPED SHORT OF PREVENTATIVE SAFETY MEASURES OF REPLACING THIS ASSEMBLY PRIOR TO FAILURE, LEADING TO AN ALMOST COLLISION EVENT FOR ME. INDEPENDENT RESEARCH HAS IDENTIFIED THIS ISSUE HAS BEEN RESPONSIBLE FOR OTHER TOYOTA PRIUS ACCIDENTS LEADING ME TO BELIEVE THIS IS A SAFETY ISSUE THAT SHOULD BE ADDRESSED BY THE NHTSA BEFORE OTHERS EXPERIENCE A CRITICAL SAFETY FAILURE AT NO FAULT OF THEIR OWN.

I WAS COMFORTABLY DRIVING MY 2010 TOYOTA PRIUS DOWN A CITY STREET ON A THURSDAY AFTERNOON--ABOUT 25 MPH, LIGHT TRAFFIC--WHEN SUDDENLY--WITHOUT ANY TRIGGER OR WARNING--I LIGHTLY PRESSED DOWN THE BRAKE PEDAL TO SLOW DOWN FOR A SPEED BUMP, AND THE BRAKES SHUDDERED, THE BRAKE PEDAL SEEMED TO TWITCH, AND THE CAR STARTED MAKING A LOUD SHRIEKING AND GRINDING NOISE EVERY 3-5 SECONDS. FOR THE RECORD, MY 2010 TOYOTA PRIUS HAS BEEN REGULARLY SERVICED AT MY LOCAL TOYOTA DEALERSHIP SINCE I PURCHASED IT IN 2018. THE LOUD SHRIEKING FELT LIKE IT WAS COMING FROM BELOW MY FEET AND FROM THE DRIVE SHAFT. I PULLED OVER--THE SHRIEKING AND GRINDING CONTINUED. I STOPPED THE CAR--THE SHRIEKING AND GRINDING CONTINUED. I GOT OUT OF THE CAR--THE SHRIEKING AND GRINDING SLOWED AFTER A FEW MINUTES. WHEN I TURNED THE CAR ON AGAIN, THE SHRIEKING AND GRINDING STARTED AND THE CAR WAS BEEPING IN A WAY I'D NEVER HEARD BEFORE. FORTUNATELY, I WAS ABOUT 4 BLOCKS FROM MY LOCAL TOYOTA DEALERSHIP. I ASKED THEM IF I WAS SAFE TO DRIVE THE FOUR BLOCKS OR IF I SHOULD GET THE CAR TOWED, AND THEY SAID I SHOULD BE SAFE TO DRIVE. I DROVE TO THE DEALERSHIP WITH THE CAR SHRIEKING AND BEEPING. THE BRAKES FELT SQUISHY AND UNRELIABLE, BUT THE DEALERSHIP HAS SAID I SHOULD BE FINE. I DROPPED OFF THE CAR. THE NEXT DAY, I GOT A CALL FROM THE DEALERSHIP SAYING THAT MY BRAKE BOOSTER PUMP AND BRAKE CYLINDER ASSEMBLY HAD TOTALLY FAILED. WHEN I ASKED THE TECHNICIAN IF THERE WAS SOMETHING I COULD HAVE DONE TO PREVENT THIS, HE SAID, 'NO, THIS IS JUST SOMETHING THAT HAPPENS TO THESE CARS.' THE BRAKE FAILURE OCCURRED ON THURSDAY, AUGUST 27, 2020. THE PHONE CALL FROM THE DEALERSHIP OCCURRED ON FRIDAY, AUGUST 28, 2020.

ABS SYSTEM WENT OUT.

THE RED BRAKES LIGHT, ABS LIGHT AND THE 'YELLOW SKIDDING CAR' ICON LIGHTS ALL COME ON TOGETHER, BUT INTERMITTENTLY. THE BRAKES OFTEN FEEL DIFFICULT TO PRESS DOWN UPON STARTING THE CAR. OFTER WHEN THE LIGHTS ARE ON, THE BRAKES FEEL SPONGY, OR AS THOUGH THEY MAY NOT STOP THE CAR. I TOOK THE CAR TO THE TOYOTA DEALERSHIP AND THEY CONCLUDED THAT THE MASTER CYLINDER AND OTHER PARTS NEEDED REPLACING. I FOUND OUT THAT TOYOTA HAS HAD LOTS OF PROBLEMS WITH THESE BRAKE CYLINDERS.

I EXPERIENCED A SIGNIFICANT LOSS OF BRAKE PERFORMANCE ACCOMPANIED BY MANY WARNING LIGHTS ON THE DASHBOARD, INCLUDING ONE THAT INDICATED A PROBLEM WITH THE ABS BRAKE SYSTEM IN MY 2010 PRIUS. UPON IMMEDIATELY TAKING THE CAR TO THE DEALERSHIP, I WAS TOLD THAT TOYOTA EXTENDED A WARRANTY PROGRAM (ZJB & ZKK) FOR THE SOURCE OF THE PROBLEM ABS BRAKE ACTUATOR/MASTER CYLINDER FAILURE, BUT THAT I WAS NOT ELIGIBLE FOR THE WARRANTY COVERAGE BECAUSE THE DEADLINE HAD EXPIRED. MY CAR WAS UNDER 150,000 MILES, AS REQUIRED BY THE WARRANTY, AND DISPLAYED THE CORRECT FAILURE CODE AS REQUIRED BY THE WARRANTY. BUT, SINCE MY CAR DID NOT EXPERIENCE THE PROBLEM OR DISPLAY AN ERROR CODE BEFORE THE END OF FEBRUARY 2020, I WAS TOLD THAT I WAS INELIGIBLE. I WAS INFORMED THAT I WOULD HAVE TO PAY OVER $4100 FOR A REPAIR THROUGH THE DEALERSHIP, BUY A NEW CAR OR TAKE MY CHANCES AND DRIVE THE CAR 'AS IS' UNTIL I COULD FIND A CHEAPER SOLUTION. THE CHEAPER SOLUTION WOULD BE TO FIND ANOTHER ABS UNIT AT A SALVAGE YARD, AND HAVE A NON-TOYOTA CERTIFIED MECHANIC INSTALL IT. THERE IS NOTHING TO INDICATE A SALVAGE YARD UNIT WILL NOT SIMPLY FAIL AGAIN. I WAS WELL WITHIN THE 150,000 MILE LIMIT OF THE WARRANTY. SO, I AM TO ACCEPT RESPONSIBILITY FOR THE REPAIR OF A PART THAT TOYOTA ADMITS IS FAULTY, AND WOULD HAVE REPLACED IF THE PROBLEM WOULD HAVE SURFACED A MERE SIX MONTHS EARLIER? I BELIEVE TOYOTA'S WARRANTY EXTENSION TO BE A MEAGER ATTEMPT AT APPEASING THE NHTSA AND OTHER AUTHORITIES SO THEY DO NOT HAVE TO LAUNCH A FULL SCALE RECALL. THEY ARE ENDANGERING THE LIVES OF HUNDREDS OF THOUSANDS OF PEOPLE WHO DEPEND ON THESE CARS ON A DAILY BASIS, AS THEY SHOULD NOT ASK THEIR CUSTOMERS TO EXPERIENCE A MAJOR BRAKE FAILURE BEFORE THE MANUFACTURER WILL AGREE TO FIX A KNOWN PROBLEM (OR NOT FIX IT, RATHER, AS THE TIME LIMIT HAS EXPIRED). TOYOTA IS PUTTING PROFITS AHEAD OF SAFETY, DURING A PANDEMIC. I THE NHTSA TO HELP US.

BRAKES SYSTEM WARNING INDICATORS LIGHT UP. BRAKES FEEL WEAK, NEED TO STEP HARDER THAN NORMAL TO START SLOWING DOWN. I LOOKED THIS UP ON THE INTERNET AND THIS A KNOWN DEFECT THAT TOYOTA COVERS UNDER 'CUSTOMER SUPPORT PROGRAM ZJB' FOR A CERTAIN PERIOD ONLY. OF COURSE IT HAPPENS RIGHT AFTER THAT COVERAGE PERIOD. THIS SHOULD BE A RECALL AS IT AFFECTS A KNOWN SAFETY ISSUE.

THE BRAKES WENT COMPLETELY OUT ON THE VEHICLE WHILE DRIVING ON THE HIGHWAY. I HAD NO ABILITY AT ALL OTHER THAN THE EMERGENCY BRAKE. THE DEALER SAID THAT THE CAUSE WAS THE BRAKE BOOSTER AND MASTER BRAKE CYLINDER.

I WAS AT HIGHWAY SPEED WHEN FOUR ANNUNCIATOR LIGHTS ILLUMINATED ON THE DASH (MASTER WARNING, BRAKE SYSTEM WARNING LIGHT, ABS WARNING LIGHT, SLIP INDICATOR). I DECELERATED VEHICLE USING ENGINE POWER THEN APPLIED BRAKES. BRAKE PEDAL DEPRESSED APPROX. 3/4 TRAVEL (MUCH FURTHER THAN NORMAL) BEFORE BRAKING ACTION FELT. I STOPPED VEHICLE, RECYCLED POWER AND WARNING LIGHTS REMAINED ILLUMINATED AND BRAKE RESPONSIVENESS WAS UNCHANGED. UPON REACHING DESTINATION, I DOWNLOADED ERROR CODE (C1391) THEN CALLED LOCAL TOYOTA SERVICE CENTER. INFORMED THAT ENHANCED WARRANTY LETTER ZJB ADDRESSED THIS ISSUE, HOWEVER COVERAGE EXPIRED 6 WEEKS AGO. SERVICE CENTER DIRECTED ME TO TOYOTA CUSTOMER CARE. TOYOTA CUSTOMER CARE CONFIRMED THAT THE REPAIR COVERAGE HAD RECENTLY EXPIRED AND THEY WERE NOT ABLE TO OFFER ANY ASSISTANCE WHATSOEVER. DUE TO THE GLOBAL PANDEMIC, MY DRIVING HAD BEEN SEVERELY CURTAILED SINCE MARCH. NOW JULY, A REQUIRED WORK TRIP LED TO THIS MALFUNCTION. THIS ISSUE SHOULD BE CLASSIFIED AS A RECALL AND NOT A WARRANTY WITH AN EXPIRATION. A MAJOR, FLEE-WIDE BRAKING ISSUE SHOULD REQUIRE THE MANUFACTURER TO REPAIR.

THE BRAKES FAILED ON THE VEHICLE AND I LOST ALL ABILITY TO STOP. SEVERAL DASHBOARD LIGHTS WERE TRIGGERED ABOUT LOSS OF ABS AND BRAKING. I WAS ABLE TO STOP THE VEHICLE ONLY THROUGH THE EMERGENCY BRAKE. THE TOYOTA DEALER INDICATED THAT THE PROBLEM WAS A FAILED BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES. THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THIS ISSUE AND TPYOTA NEEDS TO RECALL AND REPAIR THIS IISSUE.

TRACTION WARNING LIGHT, BRAKE LIGHT AND ABS LIGHT ALL CAME ON AT SAME TIME WHILE DRIVING ON THE HIGHWAY. I WAS TOLD BY A TOYOTA DEALERSHIP IT IS A MALFUNCTION WITH THE BRAKE BOOSTER WHICH IS ROUGHLY A $3000.00 REPAIR JOB AT TOYOTA DEALERSHIP. CUSTOMER SUPPORT PROGRAM "ZJB" WAS CREATED BY TOYOTA NORTH AMERICA FOR THIS ISSUE IN RESPONSE TO THOUSANDS OF PRIUS MODELS EXPERIENCING THIS SEVERE MALFUNCTION, HOWEVER, MY 2010 PRIUS IS NO LONGER ELIGIBLE FOR COVERAGE FOR THIS REPAIR, EVEN THOUGH OTHER PRIUS MODELS ARE STILL ELIGIBLE FOR COMPLETE COVERAGE FOR THIS REPAIR. THIS IS A SAFETY HAZARD AND TOYOTA NORTH AMERICA NEEDS TO STAND BY COVERAGE FOR THIS GRAVE MALFUNCTION FOR ALL MODELS REGARDLESS OF YEAR OR MILEAGE. THE DEALERSHIP TOLD ME THE CAR IS NOT SAFE TO DRIVE, THE BRAKES ARE NOT OPERATING AT FULL CAPACITY. THIS IS A SAFETY HAZARD AND HAPPENED WHILE I WAS DRIVING ON THE HIGHWAY. *TR

TL* THE CONTACT OWNED A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE HER HUSBAND WAS DRIVING AT 40 MPH, THE VEHICLE IN FRONT SUDDENLY STOPPED, THE BRAKE PEDAL WAS DEPRESSED HOWEVER IT FAILED TO ENGAGE CAUSING HIM TO REAR END THE OTHER VEHICLE. THE CONTACT MENTIONED THAT HER HUSBAND WAS ALREADY DEPRESSING THE BRAKE PEDAL WHEN THEY COMPLETELY FAILED. THE AIR BAGS DID NOT DEPLOY. THE CONTACT STATED THAT THE FRONT SEAT PASSENGER IN THE OTHER VEHICLE WAS TRANSPORTED TO THE HOSPITAL BY AMBULANCE DUE TO FEELING NAUSEOUS. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO AUTO BODY REPAIR FACILITY WHERE IT WAS AWAITING INSPECTION BY THE INSURANCE COMPANY. THE CONTACT STATED THAT THE VEHICLE WAS A POSSIBLE TOTAL LOSS AAS THE RADIATOR AND ENGINE WAS DAMAGED. THE VEHICLE HAD BEEN SERVICED AT CLEARWATER TOYOTA (21799 US HWY 19 N, CLEARWATER, FL 33765 800-667-905) FOR A BRAKE ISSUE. THE DEALER REFUSED TO REPAIR THE BRAKES UNDER AN EXTENDED WARRANTY DUE TO AN INCORRECT CONSISTENT FAILURE CODE. THE MANUFACTURER STATED THAT THE SENSOR WAS NOT ALERTING ENOUGH FOR THE REPAIRS TO BE COVERED. THE FAILURE MILEAGE WAS 200,000.

WHILE DRIVING ON THE HIGHWAY THE ABS WARNING LIGHT, BRAKE LIGHT AND TRACTION LIGHT ALL CAME ON AT ONCE, TOOK TO LOCAL TOYOTA SPECIALIST, DIAGNOSED THE CODE AS C1391, AN ABNORMAL LEAK IN BREAK BOOSTER ACCUMULATOR. MECHANIC INFORMED ME THAT THIS ISSUE WAS PREVIOUSLY UNDER SAFETY RECALL AND MY VEHICLE HAD THE PROPER REPAIRS DONE, CLEARLY THIS IS AN ONGOING SAFETY ISSUE WITH THIS VEHICLE THAT IS NOT BEING PROPERLY ADDRESSED BY TOYOTA. IT IS ALSO AN EXTREMELY EXPENSIVE REPAIR WHICH TOYOTA NEEDS TO BE FINANCIALLY RESPONSIBLE FOR. *TR

BRAKES FAILED WHILE DRIVING CAR (IN MOTION) WHICH ALMOST CAUSED AN ACCIDENT. THE RED WARNING "BRAKE" LIGHT, YELLOW "ABS" AND YELLOW TRACTION CONTROL LIGHT ALL ILLUMINATED. THIS APPARENTLY IS A KNOWN ISSUE FOR THE TOYOTA PRIUS AND I HAVE CONTACTED THEM CONCERNING THE ISSUE BUT THEY WILL NOT PAY TO FIX THE PROBLEM. MY CAR CANNOT BE DRIVEN AT THIS POINT. THIS ISSUE IS A SERIOUS HAZARD AND COULD EASILY RESULT IN AN ACCIDENT. THEY NEED TO ISSUE A RECALL. *TR

ON FRIDAY, MAY 15 2020 I TURNED ON MY CAR AND SAW ABS, BRAKE AND VEHICLE TRACTION LIGHTS ILLUMINATED. THE BRAKE PEDDLE ALSO FELT ODD. WITHIN 30 MINUTES I TOOK IT TO MY LOCAL TOYOTA DEALER. THE SERVICE WRITER HAD A CLEAR IDEA OF WHAT WAS HAPPENING AS SHE SAID THIS HAS BEEN HAPPENING A LOT TO PRIUS MODELS. SURE ENOUGH THE DIAGNOSTIC CODE C1391. I WAS TOLD I NEEDED TO REPLACE THE BRAKE BOOSTER/PUMP ASSEMBLY WHICH WOULD COST ME $3,000! UPON RESEARCH, MY CAR WAS COVERED UNDER A TSB TILL NOVEMBER 30, 2019, BUT ONLY IF THEY FAILED. THERE WAS NO RECALL ISSUED BY TMS TO PRO-ACTIVELY FIX A KNOWN BRAKE DEFICIENCY. MY CAR HAS 159,000 MILES, I HAVE NEVER HAD ANYONE SERVICE MY VEHICLE BESIDES TOYOTA DEALERSHIPS (EXCEPT TIRES). I CALLED TMS TO CORPORATE TO SEE IF I COULD BE OFFERED ASSISTANCE, BUT WAS FLAT OUT DENIED (I CAN PROVIDE THAT CASE NUMBER IF NEEDED).I FIND IT ODD THAT TOYOTA BEGAN PHASE2 ON 2011-2015 FOR SAME ISSUE THAT LASTS TILL APRIL 2021. IT IS UNSETTLING THAT IF TOYOTA KNOWS ABOUT THE BRAKE BOOSTER AND PUMP PROBLEMS, WHY THEY DON'T HAVE A RECALL, BUT RATHER A WAIT AND SEE IF IT FAILS UNDER THEIR 'SECONDARY/ENHANCED WARRANTY'. UPSET THAT IF THIS HAPPENED 5 MONTHS AGO, THIS WOULD HAVE FALLEN UNDER THEIR GUIDELINE TO REPAIR.

THE PRIUS HAVE BEEN GREAT AND HAVE BEEN SERVICED WITH OIL CHANGES, SPARK PLUGS ETC. IT RUNS LIKE A CHAMP WITH 159K MILES, BUT ALL OF A SUDDEN ONE DAY, THE TRACTION CONTROL, ABS, AND BRAKE LIGHTS ALL CAME ON AT ONCE. THE BRAKE PRESSURE FEELS SOFTER AND THAT WHIRRING NOISE IS HEARD EVERY FEW SECONDS. DEALERSHIP SAID IT WAS THE BRAKE ACTUATOR AND WOULD COST 3K TO FIX. APPARENTLY THERE WAS AN EXTENDED WARRANTY FOR IT BUT IT ENDED IN NOVEMBER 2019. ATTEMPTED TO CALL TOYOTA, BUT NO HELP. *TR

ABS BREAK PARKING LIGHT COME ON

WHILE DRIVING, WE MADE A LEFT TURN ON A CITY STREET, WARNING LIGHTS FOR ABS, STABILITY CONTROL, AND WARNING LIGHTS ALL CAME ON AT ONCE. BRAKES BECAME SPONGY WHEN PRESSED. WAS ABLE TO STILL BRAKE BUT WITH MUCH MORE EFFORT AND NOT CONFIDENT IN THE BRAKING. I HAD IT TOWED TO A LOCAL MECHANIC AND THE DIAGNOSTIC ERROR CODE REGISTERED "C1391". PER MECHANIC THIS IS FOR ABS ACCULATOR, OR BOOSTER PUMP FAILURE OR LEAK PER MECHANIC. THIS HAPPENED OUT OF THE BLUE, NO WARNINGS. LUCKILY WHILE DRIVING WE WERE DRIVING IN TOWN AND AT A SPEED OF ONLY ABOUT 15-25 MPH AND WE WERE NOT ON THE FREE WAY OR AT HIGH SPEED. PER TOYOTA THE PART REQUIRED ARE CYLINDER ASSEMBLY BRAKE AND BRAKE PUMP ASSEMBLY. COST TO REPAIR THESE PARTS PER TOYOTA WOULD BE ESTIMATED AT $2700. LOCAL DEALERSHIP WOULDN'T DO ANYTHING UNTIL IT REGISTERED THE CODE AGAIN. THE DEALERSHIP SERVICE ADVISOR, SAID UNTIL THE CODE IS TRIGGERED AGAIN THEY WOULDN'T DO ANYTHING. ALSO AFTER THE CODE WAS RESET THE BRAKES WORKED NORMAL AGAIN. THIS IN MY OPINION IS A SAFETY ISSUE! *TR

I WAS DRIVING AT A SPEED AROUND 60 MPH AND HAD TO BREAK SUDDENLY AND THE CAR DID NOT BREAK RIGHT AWAY AND TOOK MORE THAN NORMAL TO SLOW DOWN. I JUST HAD THE INSPECTION A MONTH AGO AND I WAS SAID I HAD PLENTY OF BREAKS LEFT.

WHEN I WAS DRIVING ON WEST PACES ROAD IN ATLANTA, I TRIED TO BRAKE AND THE BARAKES DID NOT WORK . THEREFORE I WENT DIRECTLY INTO THE BACK OF THE CAR IN FRONT OF ME. I MUST PRECISE THAT THE BRAKES PAD WERE NEW, THE BRAKE LIQUID WAS OK. I WAS DRIVING AT 30 MILES AN HOUR.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE TRAVELING 20 MPH, THE ANTI-LOCK BRAKE SYSTEM, STABILITY CONTROL AND BRAKE WARNING INDICATORS ILLUMINATED AND THE VEHICLE BRAKE ABILITY BEGAN TO DELAY. THE VEHICLE WAS DRIVEN TO AN INDEPENDENT MECHANIC, THEY DETERMINED THAT THE BRAKE BOOSTER HAD TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR A DIAGNOSTIC. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 230,000.

BRAKES FAIL WHEN APPLIED STEADILY WHILE MOVING ON A WET OR BUMPY SURFACE CAUSING THE CAR TO CONTINUE FORWARD UNLESS THE PEDDLE IS PRESSED AGAIN FIRMLY. THIS HAPPENS ON THE CITY STREETS WHILE MOVING IN A STRAIGHT LINE. THIS APPEARS TO BE DUE TO THE KNOWN ABS PROBLEM IN THE 2010 PRIUS AND WAS SUPPOSED TO HAVE BEEN CORRECTED BYWAY OF A SOFTWARE PATCH, WHICH I AM TOLD BY CHUCK PATTERSON CHICO TOYOTA HAS ALREADY BEEN DONE AND NO FURTHER EHLP COULD BE EXPECTED FROM TOYOTA.

NOTICED BRAKES PULSING AT VERY SLOW SPEEDS. LOOKED UP SYMPTOMS ONLINE AND DETERMINED IT WAS FROM BRAKE BOOSTER LEAK ISSUE. TOOK TO DEALERSHIP BUT BECAUSE NO CODES SHOWED UP ON DIAGNOSTIC MACHINE, WAS TOLD NOTHING WRONG. (THAT WAS AT 147,000 MILES.) FAST FORWARD 6 MONTHS AND WARNING LIGHTS CAME ON WHILE DRIVING AND BRAKING BECAME VERY SPONGY. TOOK BACK TO DEALERSHIP AND NEEDS BRAKE BOOSTER PUMP AND BRAKE CYLINDER ASSEMBLY REPLACED. NOW HAS 155,000 MILES AND IS 5000 MILES PAST WARRANTY. LONG STORY SHORT IS THAT I WAS ABLE TO DETERMINE AN ISSUE LONG BEFORE THEIR COMPUTER COULD DETECT ANYTHING. BUT BECAUSE I'M NOW PAST WARRANTY, I HAVE TO PAY $2600 FOR REPAIR.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE ABS AND TRACTION CONTROL WARNING LIGHTS ILLUMINATED AND REMAINED ILLUMINATED. THE CONTACT STATED THAT THE BRAKE PEDAL WAS DEPRESSED AND WENT TO THE FLOORBOARD EXTENDING THE BRAKING DISTANCE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED WITH A DEFECTIVE ABS CONTROL UNIT. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 10V039000 (SERVICE BRAKES, AIR). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 128,000.

I WAS DRIVING ON THE HIGHWAY AT ABOUT 60 MPH WHEN THE BRAKE LIGHT, ABS LIGHT AND SLIDE LIGHT ILLUMINATED ON THE DASH. I TOOK THE CAR TO THE DEALER AND THEY SAID IT WAS THE BRAKE ACTUATOR. WHEN I RESEARCHED THIS,I FOUND THAT IT IS A KNOWN PROBLEM TOTOYOTA AND THEY DID A VOLUNTARY RECALL. MY QUESTION IS WHY WOULD THERE BE A VOLUNTARY RECALL ON A PART THAT IS VITAL TO THE SAFETY OF THE CAR AND HAS A KNOWN DEFECT? BECAUSE IT WAS A VOLUNTARY RECALL THEY COULD ARBITRARILY SELECT A CUT OFF (150,000 MILES) INSTEAD OF ENSURING THE CAR WAS SAFE. THIS IS ONLY FOR 2010 PRIUS.

MY BRAKES HAVE FAILED DUE TO A FAULTY BRAKE ACCUMULATOR AND BRAKE BOOSTER ON MY 2010 TOYOTA PRIUS. I NOTICED THIS PROBLEM WHEN ATTEMPTING TO COME TO A STOP AT A REDLIGHT. THE BRAKES FELT SPONGY AND UNRESPONSIVE. I NARROWLY MISSED COLLIDING WITH THE CAR IN FRONT OF ME BY SWERVING ONTO THE SHOULDER. TOYOTA PREVIOUSLY ACKNOWLEDGED THIS FAULTY PART BUT CLAIMS THAT I MISSED THE DEADLINE BY 35 DAYS TO GET IT FIXED. THE REPAIR COSTS ROUGHLY $4,000 WHICH TOYOTA HAS REFUSE DO TO ACCEPT RESPONSIBILITY FOR. I CANNOT AFFORD TO FIX THIS AND BELIEVE THAT IT IS IRRESPONSIBLE FOR TOYOTA TO PUT THEIR PROFITS ABOVE THE SAFETY OF ITS' CUSTOMERS. I DO NO THIS BELIEVE THAT IT IS ETHICAL TO PUT A DEADLINE ON A SAFETY CONCERN OF THIS NATURE.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE PARKED ON A SMALL HILL, UPON STARTING THE VEHICLE AND SHIFTING TO DRIVE THE VEHICLE STARTED TO ROLL FORWARD DOWN THE HILL. THE BRAKE WAS APPLIED BUT FAILED TO ENGAGE AS THE VEHICLE COLLIDED WITH A NEIGHBOR'S FENCE AND TRAILER. THE BRAKE WARNING WAS LIGHT ILLUMINATED DURING THE FAILURE. THE CONTACT STATED THAT THE PASSENGER SUSTAINED BRUISING TO THE KNEE AS WELL AS HE ALSO SUSTAINED BRUISING TO THE KNEE THAT REQUIRED NO MEDICAL ATTENTION. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TAKEN TO LAKELAND TOYOTA (2925 MALL HILL DR, LAKELAND, FL 33810) WHERE THE BRAKES WERE REPAIRED. THE CONTACT STATED THAT THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND THE VEHICLE WAS INSPECTED BY A TOYOTA ENGINEER ASSISTANCE FIELD INSPECTOR. THE FAILURE MILEAGE WAS APPROXIMATELY 197,356.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKE BOOSTER ASSEMBLY ON THE VEHICLE WAS DEFECTIVE AND FAILED TO OPERATE AS NEEDED. THE VEHICLE WAS TAKEN TO (GREENTREE TOYOTA 87 FEDERAL RD, DANBURY, CT 06811) TO BE DIAGNOSED. THE MECHANIC WAS UNABLE TO RETRIEVE A FAULT CODE. THE VEHICLE WAS THEN TAKEN TO (CURRY TOYOTA OF CONNECTICUT 832 STRAITS TURNPIKE, WATERTOWN, CT 06795) FOR A SECOND DIAGNOSIS WITH THE SAME RESULTS. THE CONTACT BECAME AWARE OF NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE VEHICLE WAS NOT REPAIRED. THE CONTACT RECEIVED A BUYBACK OFFER FROM GREEN TREE TOYOTA BUT DECLINED THE OFFER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 93,000.

I BOUGHT THIS CAR AROUND MID YEAR OF 2019, AND WHEN I FIRST USED IT IN THE HIGHWAY COMING BACK FROM WORK, THERE WAS TRAFFIC AND I NOTICED THE BREAKS NOT RESPONDING WELL. THIS HAS HAPPENED MANY TIMES SINCE I BOUGHT IT, IN THE STREETS AS WELL. THERE'S ALSO A ORANGE LIGHT SAYING THAT IT NEEDS MAINTENANCE. I HAVE TAKEN THE CAR ABOUT 3 TIMES TO THE PERSON THAT SOLD IT TO ME BECAUSE HE HAS A CAR SHOP AND IT STILL DOES THE SAME THING.

HAZARD LIGHTS FLASHING WHEN DRIVING FORWARD OR REVERSE DEPENDENT ON THE SPEED OF WHEEL ROTATION. I AM TOLD THAT MY SKID CONTROL ECU AS WELL AS THE BRAKE BOOSTER AND PUMP ARE BAD AND NEED REPLACING. I KEEP READING ABOUT THIS ISSUE, BUT TOYOTA SAYS IT IS NOT A BROAD ISSUE. IT IS NOT CLEAR WHAT SYSTEMS HAVE FAILED OR WHAT RISK THERE IS IN DRIVING.

THE NIGHT BEFORE, EVERYTHING WAS WORKING FINE. THE NEXT DAY, I START MY CAR UP AT 4PM-5PM, FIRST TIME I STARTED MY CAR AND I HAVE NEW LIGHTS ON MY DASHBOARD. THE EBRAKE LIGHT, ABS LIGHT, BRAKE SYSTEM LIGHT, AND TRACTION LIGHT. I RELEASE MY EBRAKE AND THE EBRAKE LIGHT IS STILL ON. CONCERED I CHECKED THE BREAK FLUID AND THE 12V BATTERY AND THOSE WERE FINE. DROVE THE CAR AROUND THE BLOCK TO SEE IF THERE WAS AN ISSUE OR IF THE LIGHTS WERE JUST ON. THE BRAKES WERE ALMOST COMPLETELY OUT THE VEHICLE WOULD ONLY STOP WHEN I PUT MY FOOT TO THE FLOOR. I END UP TAKING THE VEHICLE TO MY LOCAL TOYOTA DEALERSHIP WERE AFTER FOUR HOURS OF LOOKING AROUND, INFORMED ME THAT IT WAS THE BRAKE ACTUATOR AND THE BOOSTER PUMP. WHICH ALSO CAME WITH A BILL OF $3000 TO FIX IT.

VEHICLE ACTUATOR BRAKE PUMP ASSEMBLY MAKING SQUEAKING BARKING NOISES WHEN THE BRAKE IS PRESSED DOWN AND HELD DOWN THE BRAKE PUMPS BACK AT ME. I TOOK TO TOYOTA THEY CHARGED ME FOR RUNNING CODES AND TWO BRAKE BLEEDS. AGKNOWLEDGED THAT IT'S THE BREAK ACTUATOR PUMP ASSEMBLY THAT IS A EXTENDED WARRENTY BUT WILL NOT FIX AND CHARGED ME BECAUSE THE WARNING LIGHT SYSTEM IS NOT COMING ON. THIS SHOULD BE A RECALL NOT AN EXTENDED WARRENTY. MY BRAKES BARK AND PUSH BACK EVERY TIME I BRAKE. THIS DOESN'T SEEM SAFE TO DRIVE ON THE FREEWAY AND NOT GOOD IF AN ACCIDENT INCURS BECAUSE I HAD TO WAIT UNTIL MY BRAKES DIDN'T WORK. PLEASE MAKE A RECALL AND NOT JUST AN EXTENDED WARRENTY.

MY 2010 TOYOTA PRIUS SLIDES WHILE BREAKING WHEN I DRIVE OVER A BUMP OR A WHOLE THE CAR SLIDES WHILE IN MOTION ON CITY STREETS OR HIGHWAYS. THESE OCCURRENCES HAPPEN WHILE DRIVING STRAIGHT OR TURNING. THIS OCCURS ALL THE TIME WHEN THE ROADS ARE DRY AND IT IS WORST WHEN IT IS WET OUTSIDE, ICE, RAIN SLEET OR SNOW.

I WAS MAKING A LEFT TURN, CREEPING INTO A PARKING SPACE, IN A RESIDENTIAL AREA. WHEN I PRESSED THE BRAKE PEDAL TO STOP THE CAR, THE CAR ACCELERATED INSTEAD. I THEN SLAMMED ON THE BRAKES AND THE CAR ACCELERATED AGAIN, CAUSING ME TO GO OVER THE CURB, OVER THE SIDEWALK AND KNOCK DOWN A FENCE AND SHED. I TURNED THE VEHICLE OFF, SOME KIND BYSTANDERS TOOK THE DEBRIS OFF THE CAR SO THAT I COULD GET OUT. I THEN CALLED POLICE AND THE PROPERTY OWNER, AS WELL AS MY INSURANCE COMPANY. I AM HONESTLY SCARED TO DRIVE THE CAR AGAIN, AS I DO NOT WANT THIS UNINTENDED ACCELERATION TO HAPPEN AGAIN. I WILL BE NOTIFYING TOYOTA, AND THE REPAIR SHOP WORKING ON MY CAR HAS ALREADY BEEN INFORMED.

BRAKE FAILURE AND CAR WENT UP CURB, KNOCKED DOWN STAIR RAIL, HIT TREE AND TURNED OVER ON SIDE

EVEN THOUGH THE BREAK PADS ARE NEW, THE BREAKS ARE NOT WORKING AT ALL WHEN VEHICLE IS IN MOTION. THEY DO NOT FEEL TIGHT. THE VEHICLE LOOSES STABILITY IN CURVES AT A LOW SPEED ( SLIPS) AND KEEPS MOVING EVEN WHEN BREAKS ARE PUSHED TO THE END. ALL THE BREAK LIGHTS ARE ON. THERE ARE SEVERAL RECALLS REGARDING THE BREAKS OF THIS VEHICLE YEAR 2010 AND NONE APPLIES TO THE VEHICLE VIN NUMBER. IT IT NOT RELIABLE AT ALL IN THE HIGHWAY. IN ORDER TO BRAKE THE SPEED MUST BE VERY SLOW AND THE DISTANCE MUST BE WAY MORE THAN NORMAL

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 5 MPH, THE BRAKE PEDAL WAS DEPRESSED BUT FAILED TO OPERATE. THE VEHICLE CRASHED INTO THE REAR OF ANOTHER VEHICLE. A POLICE REPORT WAS FILED. THERE WERE NO INJURIES SUSTAINED. THE VEHICLE WAS DRIVEN FROM THE CRASH SITE TO THE RESIDENCE. SUNNYSIDE TOYOTA LOCATED AT 27000 LORAIN RD, NORTH OLMSTED, OH 44070, (440) 777-9911, WAS CONTACTED AND AN APPOINTMENT WAS SCHEDULED TO HAVE THE VEHICLE DIAGNOSED WHICH WAS STILL PENDING. THE VEHICLE WAS NOT REPAIRED. THE CONTACT STATED THAT THE FAILURE WAS INTERMITTENT. THE MANUFACTURER WAS NOT CONTACTED OR NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 93,000.

ALL BRAKE, ABS, AND TRACTION CONTROL LIGHTS CAME ON. CHECKED ABS CODE AND RECEIVED C1391. MECHANIC CAN HERE THE ACTUATOR CONTINUOUSLY RUNNING AND BELIEVE THE PUMP/ACTUATOR IS BAD. I HAVE SEEN THIS RECALLED ON 2010 MADE BETWEEN MARCH 2009, AND OCTOBER 2009. MY MANUFACTURE DATE IS SEPT 2010. VEHICLE WAS IN MOTION WHEN THE LIGHTS CAME ON. THE CAR BECAME HARD TO STOP AND REGENERATIVE BRAKING IS NO LONGER WORKING.

LOUD SCREECHING NOISE AND VIBRATION AT BRAKE PEDAL. ABS BRAKE AND TRACTION LIGHTS ALL LIT UP ALONG WITH BEEPING. HAS HAPPENED SPORADICALLY OVER LAST 2 YEARS. HAVE OWENS CAR 5 YES. APPROX 120,000 MILES. WHEN THE BRAKE NOISE AND ALL LIGHTS APPEAR ON DASH VERY LOW BRAKING ABILITY. HAPPENS WHEN DRIVING OR STARING CAR. ON 6/6 LIGHTS AND BRAKING FAILED AND DO NOT TURN OFF. TOOK TO SERVICE AT TOYOTA DEALER & TECH SAYS $3000 PLUS FOR REPAIRS. POSSIBLE LEAK IN ABS PUMP??

WITHOUT WARNING, TOTAL FAILURE OF POWER ASSIST TO BRAKES. NUMEROUS DASH WARNING LIGHTS AND LOUD BUZZER SOUNDS. REQUIRES EXTREME BRAKE PEDAL FORCE TO STOP THE CAR. EXTREMELY UNNERVING AND DANGEROUS SITUATION.

STARTED CAR ONE MORNING, IMMEDIATELY NOTICED THE 'ABS', 'BRAKE', AND 'TRACTION CONTROL' WARNING LIGHTS WERE ON SIMULTANEOUSLY. TOOK THE CAR FOR A DRIVE AROUND THE CORNER, AND IMMEDIATELY NOTICED BRAKES WERE VERY SOFT AND UNRESPONSIVE. PEDAL LITERALLY SINKS TO THE FLOOR WHILE AIR CAN BE HEARD LEAKING FROM THE SYSTEM/PEDAL. . ALSO NOTICED THE BRAKES NO LONGER RECHARGE THE SYSTEM, AND THEY ALSO FEEL JERKY AT TIMES. I CHECKED THE BRAKE FLUID RESERVOIR, AND NOTICED FLUID WAS HALFWAY BETWEEN MAX AND LOW. PERHAPS A LEAK SOMEWHERE IN THE SYSTEM? I CONTACTED MY LOCAL TOYOTA DEALER AND WILL HAVE THEM TAKE A LOOK AT IT ON 05/10/2019 ACCORDING TO SOME RESEARCH I CONDUCTED, THIS IS A KNOWN ISSUE IN THE 2010/2011 MODELS. SUPPOSEDLY, OVER TIME, VIBRATIONS CAN ACTUALLY CRACK THE LINE(S) FEEDING INTO THE BRAKE MASTER CYLINDER, AND THUS RESULTING IN THIS FAULT. TOYOTA SHOULD DEFINITELY BE MORE COMMUNICATIVE ABOUT THESE ISSUES. I HAVE OWNED THIS CAR FOR 4 YEARS, AND HAVE NEVER HEARD OF THIS BEFORE. CURRENTLY NOT DRIVING THE CAR AT THE MOMENT, AS I DO NOT FEEL SAFE

THE ABS/BRAKE LIGHT/ SLIP INIDICATOR WARNING TRIANGLE ON & OFF. MY 2010 TOYOTA PRIUS II HAS 153K MILE. THIS HAS GONE ON/OFF FOR A FEW WEEKS NOW. THE BRAKE SEEMS TO LOOSE THE HYDRAULIC POWER BRAKE. I FEEL LIKE THE BRAKES HAVE FAILED A FEW TIMES WHILE DRIVING AT HIGHER SPEEDS. I HAVE TO PUMP BRAKE AND VEHICLE BEGINS TO BRAKE ON 2ND PUMP. I'VE HAD TO TRIPLE MY STOPPING DISTANCE AS TO NOT REAR ANYONE. I WENT TO AUTOSHOP, THEY SAID IT'S THE BRAKE ACTUATOR/SENSORS THAT NEED TO BE REPLACED AND IT'S EXPENSIVE $2-3K. THEY SAID IT NEED TO BE FIX SOON BECAUSE BRAKE MIGHT FAIL AT ANY TIME. I CALLED CAMELBACK TOYOTA, PHOENIX, AZ, ED IN SERVICE DEPT SAID THERE IS NO SAFETY RECALL FOR THIS EVEN THOUGH THEY KNOW IT HAS BEEN A COMMON PROBLEM WITH PRIUSES . I CHECKED VEHICLE REPAIR HISTORY LOOKS LIKE ABS PROGRAMMING WAS FLASHED BACK IN 2/11/2010, WHEN VEHICLE WAS STILL ON THE MANUFACTURER, 3 MILES. I HAVE NOT FIXED YET. PLEASE RESEARCH THIS ISSUE FURTHER FOR SAFETY REASONS. I DO NOT WANT TO KILL ANYONE WHEN BRAKES WILL EVENTUALLY FAIL.

WHEN THE BRAKES ARE APPLIED AND GOING OVER A ROUGH ROAD SURFACE, OR POTHOLE, THE BRAKE WARNING LIGHT APPEARS, AND THE BRAKES SUDDENLY STOP FUNCTIONING UNTIL BACK ON A SMOOTH ROAD SURFACE. THIS HAPPENS ALL OF THE TIME UNDER THESE CONDITIONS. IT IS REALLY SCARY WHEN THE VEHICLE SUDDENLY LOSES ALL BRAKING WHILE TRYING TO STOP. I HAVE A 2010 TOYOTA PRIUS AND A 2012 TOYOTA PRIUS. THEY BOTH HAVE THE SAME PROBLEM WITH THE ABS BRAKING SYSTEM. CANNOT UNDERSTAND WHY THIS IS NOT A FULL RECALL ON THIS POTENTIALLY DANGEROUS CONDITION.

THE CAR WAS MOVING WHEN THE TRACTION LIGHT, ABS LIGHT AND BRAKE LIGHTS ALL CAME ON. THHE BRAKES FELT A LITTLE DIFFERENT THEN. I COULD STILL BRAKE BUT THEY WERE MORE STIFF.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES MADE AN ABNORMAL NOISE AND THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD WHEN DEPRESSED. ALSO, VARIOUS WARNING INDICATORS AND GAUGES REMAINED ILLUMINATED ON THE INSTRUMENT PANEL. THE CONTACT HAD TO APPLY FORCE TO THE BRAKE PEDAL DUE TO THE FAILURE. THE VEHICLE WAS EXCLUDED FROM NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES), ALTHOUGH THE VEHICLE EXHIBITED THE SAME FAILURE AS LISTED IN THE RECALL CAMPAIGN. TOYOTA OF HOLLYWOOD (6000 HOLLYWOOD BLVD, LOS ANGELES, CA 90028, (323) 498-2260) WAS NOTIFIED AND DIAGNOSED THAT THE BRAKE ACTUATOR NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND EXCLUDED THE VEHICLE FROM THE BRAKE SYSTEM RECALL. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.

UPON BRAKING (EXACERBATED BY WET OR SLIPPERY CONDITIONS AND HARD BRAKING) THE ABS SYSTEM DOES NOT BEHAVE AS EXPECTED. INSTEAD OF PULSATING TO MODULATE THE AMOUNT OF BRAKING FORCE AND SLOWING DOWN THE VEHICLE THE BRAKES WILL COMPLETELY STOP ENGAGING WHILE THE CAR TRAVELS A MODERATE DISTANCE (E.G. 10 FEET) BEFORE THE BRAKES KICK IN AGAIN.

ABS SYSTEM COMPLETELY FAILED WHILE DRIVING, NO ACCIDENT OCCURRED BUT DEFINITELY COULD HAVE. VEHICLE WAS TAKEN TO DEALER AND I WAS TOLD THERE WAS A RECALL FOR THE ABS SYSTEM ON THE VEHICLE BUT THEY DECLINED FIXING IT FREE OF CHARGE DUE TO MILEAGE, AND THEY GAVE ME A QUOTE OF $3000 TO FIX A PROBLEM THAT THEY HAVE NOT TAKEN RESPONSIBILITY FOR A KNOW ABOUT. TO MY UNDERSTANDING A RECALL IS A RECALL REGARDLESS TO MILEAGE AND I ALSO ASKED THE DEALER ABOUT THE PROBLEM 1 YEAR AGO AND WAS TOLD IT WAS NO PROBLEM.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE BRAKES WERE ENGAGED AND THE VEHICLE WAS STATIONARY, A LOUD ABNORMAL NOISE WAS HEARD FROM UNDER THE HOOD. THE VEHICLE WAS TAKEN TO GERMAIN TOYOTA OF NAPLES (13315 TAMIAMI TRAIL N, NAPLES, FL 34110, (888) 722-4942) WHERE THE CONTACT WAS INFORMED THAT THE MASTER CYLINDER NEEDED TO BE REPLACED AND THE LINEAR OFF SET VALUE NEEDED TO BE RE-LEARNED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 111,399.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 35 MPH, THE VEHICLE FAILED TO STOP WHEN THE BRAKE PEDAL WAS DEPRESSED. THE CONTACT HAD TO APPLY THE EMERGENCY BRAKE TO STOP THE VEHICLE. THE CONTACT STATED THAT THE VEHICLE EXHIBITED THE SAME SYMPTOMS AS LISTED IN NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE VEHICLE WAS TAKEN TO TOYOTA OF POWAY (13631 POWAY RD, POWAY, CA 92064, 858-486-2900) TO BE DIAGNOSED, BUT THE FAILURE COULD NOT BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED THE CONTACT THEY WOULD SEND HER A CLAIM NUMBER. THE FAILURE MILEAGE WAS APPROXIMATELY 137,450.

SOMETIMES AFTER STARTING THE CAR, BRAKES WILL ONLY RESPONSE TO HARD BRAKING. CANNOT BRAKE TO SLOW DOWN GRADUALLY. BRAKES WILL NOT RESPOND AT ALL WHEN LIGHTLY PRESSING DOWN ON BRAKE PEDAL. ONLY AFTER DRIVING ABOUT 1 MILE WILL NORMAL BRAKING FUNCTIONALITY RETURN. THIS HAS BEEN AN ISSUE EVER SINCE I FIRST BOUGHT MY CAR NEW.

WHEN BRAKING WHILE CAR IS GOING OVER A POTHOLE, CAR WILL BRIEFLY ACCELERATE FORWARD BEFORE STOPPING.

INTERMITTENTLY, SEVERAL WARNING LIGHTS COME ON AT ONCE WHILE DRIVING: TRACTION CONTROL, BRAKE, AND ABS LIGHTS. WHILE ON, BRAKING IS LESSENED, BRAKES FEEL SPONGY, AND THE BATTERY GENERATION INDICATOR SHOWS NO ENERGY BEING PRODUCED. I FOUND SEVERAL SIMILAR COMPLAINTS ONLINE. FOR ME, THE PROBLEM HAS COMES AND GOES, AFFECTING ABOUT 50 PERCENT OF MY DRIVING TIME.

I AM ENTERING THIS COMPLAINT BASED ON READING DOZENS OF ACCOUNTS THAT RESEMBLE MY ISSUE EXACTLY. TEN MINUTES INTO A FORTY MINUTE DRIVE THREE LIGHTS SUDDENLY CAME ON, THE BRAKE, ABS AND TRACTION CONTROL LIGHTS. THE BRAKES IMMEDIATELY BECAME SOFT, REQUIRING 50-60% MORE EFFORT TO STOP THE CAR AND DRASTICALLY REDUCED STOPPING TIME. THIS OCCURRED ON A DARK COUNTY ROAD, AFTER A LIGHT SNOWFALL AND TEMPERATURES IN THE MID-20'S. I QUICKLY PULLED INTO A CHURCH PARKING LOT TO CHECK THE BRAKE FLUID LEVEL AND FOR ANY BROKEN BRAKE LINES. I ALSO SHUT OFF THE CAR HOPING TO CLEAR THE ERROR, WHICH IT DID NOT. FLUID LEVELS LOOKED NORMAL AND I DECIDED TO PROCEED THE REMAINING 25 MILES OF MY DRIVE AFTER ENSURING THAT I COULD STOP AS NEEDED. AFTER 20 MINUTES OF DRIVING 45-55MPH THE LIGHTS TURNED OFF AND BRAKING POWER WAS INSTANTLY RESTORED TO 100%. I HAVE NOT TAKEN MY CAR INTO THE DEALER YET, BUT PLAN ON NOTIFYING THEM.

I HAD NOT ANY PROBLEM WITH BREAKS AT ALL....ONCE AFTER TAKING A LEFT TURN.......CHECK PCS SYTEM WITH OTHER LIGHTS LIKE WARNING, SLIPPARY, ABS, FRONT BREAKS,CAME ON. EMERGENCY LIGHTS KEEP FLASHING EVEN IF YOU SHUT THE CAR OFF. I TOOK OFF THE FUSE 16 FOR TURN SIGNALS...EVERYTHING CAME NORMAL....ONLY THAT I DONT HAVE TURN SIGNALS. AS SOON AS I PUT THE TURN SIGNAL FUSE BACK...EMERGENCY LIGHTS STARTED FLASHING AND CHECK PCS SYSTEM WITH ALL OTHER LIGHTS CAME ON. DEALER DIAGNOSED THE CAR FOR $ 150.00.....NO CLUE....SAID THEY WILL CHARGE ME EXTRA $550.00 TO FIND PROBLEM.....ON THE SECOND DAY EVENING THEY SAID I NEED TO REPLACE ABS ACTUATOR WILL COST ME $ 4500.00

I WAS EXITING EXIT 3 OF INTERSTATE 91 IN NEW HAVEN CT AND WAS TRYING SLOW DOWN AND STOP BUT WHEN I APPLIED THE BRAKES THERE WAS NO RESPONSE. I PUMPED THE PEDAL SEVERAL TIMES BUT THE BRAKES STILL FAILED. I STEERED THE CAR TO THE LEFT TO AVOID DIRECTLY COLLIDING WITH THE VEHICLE IN FRONT OF ME AND WOUND UP SCRAPING IT AND CRASHING INTO INTO A BARRIER. I HAVE SINCE LEARNED THAT THIS HAS BEEN AN ONGOING PROBLEM WITH THE 2010 PRIUS AND AM OUTRAGED THAT THE COMPANY HAS BEEN WILLING TO GAMBLE WITH MY SAFETY AND THAT OF OTHER PRIUS OWNERS. I DO NOT HAVE THE ABILITY TO SCAN DOCUMENTS BUT THE CLAIM NUMBER IS ALLSTATE 0523873875 AND THE CT STATE POLICE INCIDENT REPORT IS 1800537795.

MY CAR IS MAKING A WEIRD NOISE COMING FROM THE FIREWALL. MY TRACTION CONTROL LIGHTS ARE ON, BRAKE, AND A COUPLE OTHER. IT TURNS OFF AND THEN WILL TURN BACK ON.

WARNING LIGHTS : ABS , BRAKE , AND ANTI-SKID COME ON AND STAY ONE. BRAKE PEDAL IS SPONGY AND UNRESPONSIVE. THE ERROR CODE READS OUT P1241 & C1391 WHICH INDICATE BRAKE BOOSTER PUMP FAILURE. ABS BRAKES HAVE FAILED.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 55 MPH, THE PARK, ABS, AND VCS WARNING INDICATORS ILLUMINATED AND THE BRAKES BECAME DIFFICULT TO MANEUVER. THE CONTACT HAD TO DEPRESS THE BRAKE PEDAL SEVERAL TIMES TO STOP THE VEHICLE. THE CONTACT STATED THAT THE VEHICLE EXHIBITED THE SAME SYMPTOMS AS LISTED IN TSB: 0079-18. THE VEHICLE WAS NOT TAKEN TO A DEALER TO BE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 100,000.

BRAKES SLIP AND LOSE GRIP WHILE BRAKING AND TRAVELING OVER MODERATE BUMPS OR POTHOLES, ALSO HAPPENS WHILE BRAKING HARD.

PARK, ABS, VCS, (!) WARNING LIGHTS ON IN DASHBOARD. OTHER SYMPTOMS - BARKING BRAKES AND CONTINUOUS PUMP WHINE, A CYLCING ELECTRICAL NOISE WHILE PARKED. SEEMS TO BE AN ISSUE WITH THE ACTUATOR.

I RECENTLY NOTICED THAT WHEN I OPEN THE CAR DOOR TO GET INTO THE CAR (WITH THE ENGINE OFF), THE BRAKE ASSIST PRIMES FOR QUITE A BIT (> 30 SECONDS). THEN I START MY CAR, I NOTICE THAT THE SOUND CAN BE HEARD PRIMING THE BRAKE (VACUUM?) EVERY 15 SECONDS OR SO AND LASTING ABOUT 3-5 SECONDS. IT PRIMES EVERY TIME I RELEASE THE BRAKE PEDAL. THE DEALER SAID THAT THE BRAKE ACTUATOR IS BAD AND WILL NEED TO BE REPLACE OR THE CAR WILL NOT SOME IN DRIVING CONDITIONS.

ABS ACTUATOR FAILED WHILE DRIVING VEHICLE ON HIGH SPEED CITY STREET. LOSS OF BRAKING POWER NOTICED/OBSERVED. ACTUATOR FAILURE HAS BEEN CONFIRMED BY TOYOTA DEALER - CAR IS CURRENTLY BEING HELD FOR REPAIR.

ABS AND BRAKE LIGHTS "TURNED ON" ON THE DASHBOARD WHILE DRIVING ALONG FREEWAY. HAD TO PUSH THE BRAKE PEDAL HARDER TO STOP THE CAR. SEARCH ONLINE ON WHAT MIGHT BE CAUSING THE WARNING LIGHTS, IT WAS FOUND OUT THAT SO MANY TOYOTA PRIUS CAR OWNERS WERE HAVING THE SAME ISSUE. THE SYMPTOM WAS CAUSED BY EITHER FAULTY ACCUMULATOR OR MASTER CYLINDER/ACTUATOR.

THE BRAKES MAKE SOUNDS WHEN PRESSED. LOOK INTO THE INTERNET AND PRIUS CHAT FORUMS AND TAKING TO LOCAL MECHANIC AND FOUND THE BRAKE ACTUATOR IS FAULTY AND NEED REPLACING ASAP.

I WAS DRIVING TO MY HOUSE AND THE BRAKE PEDAL WENT TO THE BOTTOM. SEVERAL LIGHTS APPEARED ON THE DASHBOARD. I WAS DRIVING IN THE HIGHWAY AND FORTUNATELY THERE WAS AN EXIT AND I COULD GET OUT OF THE HIGHWAY AND I MANAGE HOW TO STOP AND I DID NOT CRASH. THE STORY COULD BE ANOTHER IF I WAS DRIVING FASTER. THE NEXT DAY I TOOK IT TO THE TOYOTA DEALER AND THEY TOLD ME THAT THE PROBLEM WAS THE BOOSTER PUMP (ATTACHED YOU CAN FIND THE ESTIMATE). I WAS SHOCKED WHEN I FOUND HOW MUCH WAS GOING TO COST ME. MY CAR HAS NEVER HAD A PROBLEM AND ALL OIL CHANGES HAD BEEN AT THE SAME TOYOTA DEALER. I HAVE NEVER TAKEN THE CAR ANYWHERE ELSE. INVESTIGATING I FOUND THAT THIS MODEL PRIUS 2010 IN 2013 HAD A RECALL FOR THIS SAME PROBLEM AFFECTING 82000 PEOPLE. I AM USING THE CAR WITH BECAUSE I HAVE TO GO OUT TO WORK EVERY DAY FOR THE SUSTENANCE OF MY FAMILY AND WITH A CONSTANT CONCERN OF HAVING AN ACCIDENT AND CAUSING DEATH TO OTHER PEOPLE INCLUDING MYSELF, I NEED THE HELP OF TOYOTA TO PAY FOR THE ENTIRETY OF ARRANGEMENT I ALREADY SPOKE WITH TOYOTA HEADQUARTERS AND THEY SAID THAT THEY WILL NOT HELP ME WITH THE COST OF THE REPAIR, IT IS REALLY EXPENSIVE AND IT IS NOT MY FAULT. DOES TOYOTA HAVE TO WAIT UNTIL THERE IS AN ACCIDENT? OR INJURY OR DEAD PEOPLE?.

I STATED TO THE GLENDALE TOYOTA DEALER IN CALIFORNIA THAT I HEAR AND FEEL A BUZZ/CLICK WHEN I STEP ON THE BRAKE AND THEY INFORMED ME IT IS THE BRAKE ACTUATOR AND WARRANTY EXPIRED IN DECEMBER 2017. I AM REQUESTING IS AN EXTENSION TO THIS WARRANTY OR VOLUNTARILY MAKE IT A SAFETY RECALL. IT IS VERY DANGEROUS AND EXPENSIVE TO FIX.

LETTER FROM CONGRESSMAN OLSON ON BEHALF OF CONSTITUENT REGARDING TOYOTA BRAKE RECALL ON HER 2010 TOYOTA PRIUS. *LD THE CONSUMER WAS CONCERNED ABOUT NOT RECEIVING A NOTICE FOR THE SAFETY RECALL FOR THE BRAKES.*JS

BRAKE PEDAL GOES TO FLOOR. BRAKE LIGHT IS ON. DEALER SAYS ACCUMULATOR PUMP IS BAD. THERE IS A RECALL FOR THIS ITEM. THEY REPLACED IT UNDER RECALL IN 2014 AND REFUSE TO DO IT AGAIN. QUOTED $2000 TO REPAIR. CALLED TOYOTA CUSTOMER SERVICE AND THEY WON'T DO ANYTHING EITHER. IT IS A SAFETY ISSUE AND STILL HAVING THE SAME SAFETY ISSUES IS NOT OK. I AM 6 MONTHS PREGNANT AND CANNOT AFFORD TO FIX AN ITEM THAT SHOULD BE COVERED FOR LIFE OF THE VEHICLE DUE TO THIS RECALL.

I TOOK MY PRIUS TO THE DEALER BECAUSE THE BRAKE LIGHT WAS ON, TO RESOLVE THE PROBLEM THE DEALER REPLACED MY MASTER CYLINDER AND BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLY. I FOUND THAT THERE IS A RECALL FOR THE 2010 PRIUS. T-CP-DOM DATE OF ISSUE JULY 1, 2013. THE RECALL IS FOR THE SAME PROBLEM I HAD, I DO NOT KNOW WHY I AM BEING EXCLUDED FROM THE RECALL. PLEASE REPLY

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 20 MPH, SEVERAL WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC AND WAS INFORMED THAT THERE WAS A RECALL FOR SIMILAR VEHICLES PER NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). DELUCA TOYOTA (1719 SW COLLEGE RD, HWY 200, OCALA, FL 34471, (352) 732-0770) WAS CONTACTED AND STATED THAT THE VEHICLE WAS NOT INCLUDED IN THE RECALL. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 166,000.

AFTER REGULAR CHECK-UPS AND MAINTENANCE AT 90000 MILES AND 8 YEARS OF DRIVING, ALL OF A SUDDEN THREE BRAKE LIGHTS CAME ON, THE ABS, HAND BRAKE, AND SKID CONTROL LIGHTS ALL CAME ON. AT THIS TIME THE BRAKING ISSUES SEEM TO BE LESS RESPONSIVE BRAKING AND SLIGHT JERKING WHEN PUTTING CONSTANT PRESSURE ON THE BRAKES AT LOW SPEEDS. WHEN BROUGHT TO THE TOYOTA DEALERSHIP, THEY NOTED THAT THERE ARE NO ISSUES, HOWEVER THE MASTER BRAKE CYLINDER IS LIKELY TO FAIL SOON.

I TOOK MY PRIUS TO THE DEALER BECAUSE THE BRAKE LIGHT WAS ON, TO RESOLVE THE PROBLEM THEY REPLACED MY MASTER CYLINDER AND BOOSTER ON MY 2010 PRIUS. I ASKED ABOUT A RECALL FOR THE PARTS. I WAS TOLD NO RECALLS, I FOUND THAT THERE IS A RECALL FOR 2010 PRIUS. T-CP-DOM DATE OF ISSUE JULY 1, 2013. THE RECALL IS FOR THE SAME PROBLEM I HAD

I'VE COUNTED AT LEAST 30 BRAKE BOOSTER/ACTUATOR COMPLAINTS ON THIS SITE YEAR TO DATE FOR THE SAME ISSUE ON THIS MODEL YEAR CAR. OUR ISSUE IS THE SAME AS EVERYONE ELSE. JUST UNDER 150K MILES, BRAKE, ABS AND TRACTION CONTROL LIGHTS CAME ON MY DAUGHTER'S CAR (WE ARE ORIGINAL OWNERS) AS SHE WAS DRIVING HOME FROM WORK. NON RESPONSIVE BRAKES, ONLY REAR BRAKES ENGAGE IF YOU PUSH THE PEDAL TO THE FLOOR OF THE CAR. TOOK TO DEALER WHO DIAGNOSED DTC C1391, ACCUMULATOR LEAK MALFUNCTION. OUR CAR WAS NOT INCLUDED IN ORIGINAL WARRANTY ENHANCEMENT (MANUFACTURE DATE OF 1/2010), SO PRICE QUOTED WAS $4814.66. OUR DAUGHTER CANNOT AFFORD, SO WE CALLED TOYOTA WARRANTY WHO OFFERED US $2007 AS A MEASURE OF GOOD WILL, BUT NO MORE. THIS IS A SERIOUS SAFETY ISSUE, BEYOND RIDICULOUS THAT SOME CARS WITH THE SAME DEFECT HAD THE WARRANTY ENHANCEMENT PROGRAM AVAILABLE WHICH PAID FOR THE ENTIRE REPAIR, YET MOST OTHERS LIKE US WERE DENIED THE FIX AND ARE FACING ASTRONOMICAL REPAIR BILLS THAT MANY CANNOT AFFORD, NOR ANTICIPATE ON A CAR SUCH AS A TOYOTA. THE BRAKES FAILED WHILE MY 22 YEAR OLD DAUGHTER WAS DRIVING - THAT COULD HAVE GONE SO VERY WRONG.

THE TRACTION LIGHT, THE ABS LIGHT AND THE BRAKE LIGHT APPEAR ON THE DASH. I HAVE ALREADY PAID THE MECHANIC APPROXIMATLY $1,500 FOR REPAIRS AND NOW I AM TOLD I NEED THE ABS BRAKE BOOSTER WHICH COSTS AN ADDITIONAL $2,546.26. THIS PART HAS BEEN RECALLED ON OTHER 2010 TOYOTA PRIUS MODELS, BUT NOT MINE. I CANNOT AFFORD THIS FIX, SO I AM DRIVING MY CAR AS IT IS. BRAKE PEDAL ACTS DIFFERENTLY EACH TIME I USE THE BRAKES.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 30 MPH AND DEPRESSING THE BRAKE PEDAL TO SLOW DOWN THE VEHICLE, THE PEDAL BECAME LOOSE. AS A RESULT, THE VEHICLE CONTINUED MOVING AND THE ANTI-SKID, BRAKE, AND ABS WARNING INDICATORS ILLUMINATED. THE CONTACT WAS ABLE TO BRING THE VEHICLE TO A STOP BY DEPRESSING THE BRAKE PEDAL MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO CAVENDER TOYOTA (5730 NORTHWEST LOOP 410, SAN ANTONIO, TX 78238, (210) 681-6601) WHERE IT WAS DIAGNOSED THAT THE POWER BOOSTER FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED DUE TO THE REPAIR FEES. THE MANUFACTURER WAS NOTIFIED AND INFORMED THE CONTACT THAT THE VIN WAS NOT INCLUDED IN ANY RECALLS; THEREFORE, NO FURTHER ASSISTANCE WAS OFFERED. THE APPROXIMATE FAILURE MILEAGE WAS 85,000.

WHILE DRIVING ON A BUMPY SURFACE THE BRAKES SLIP WHEN APPLIED. STOPPING ABILITY IS REDUCED. THIS HAPPENS ON A REGULAR BASIS, ON SURFACE STREETS AND HIGHWAYS. I HAVE NOTICED IT WHILE STOPPING IN A STRAIGHT LINE, BUT IT MAY ALSO HAPPEN WHILE STOPPING ON A CURVE.

C1391 - ABS SYSTEM FAILED

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE DELAYED TO STOP AND THE BRAKE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO SHEEHY TOYOTA OF FREDERICKSBURG (3507 JEFFERSON DAVIS HWY, FREDERICKSBURG, VA 22408, (540) 507-0076) AND WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN A RECALL. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE CONTACT REFERENCED NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE MANUFACTURER WAS NOTIFIED AND THE CONTACT WAS ADVISED TO CONTACT THE DEALER. THE FAILURE MILEAGE WAS APPROXIMATELY 250,000. *TT

BRAKE SYSTEM HAS KEPT MAKING AIR PUSHING SOUND BUT SUDDENLY I CANNOT PUSH THE BRAKE PEDAL AT ALL. IT FEEL LIKE BLOCKED. BRAKING FORCE IS NOT WORKING

SERIOUS ISSUE WITH THE PRIUS. BRAKE ACTUATOR/BRAKE BOOSTER FAIL. THE BRAKING IS SERIOUSLY COMPROMISED BECAUSE OF THIS PROBLEM. THE DEALERSHIP SAYS IT IS KNOWN TO TOYOTA, BUT THEY WILL NOT OFFER ANY ASSISTANCE. WHEN THE BRAKE/ABS/TRAC LIGHTS ARE RESET THE BRAKES FUNCTION PERFECTLY FOR A SHORT PERIOD OF TIME AND THEN THE LIGHTS/PROBLEM RETURNS.

ANTILOCK BRAKE ACTUATOR AND PUMP FAILURE. QUOTED AS A $4700 REPAIR AT DEALER WITH LABOR. PARTS ARE JUST OVER $3600. THERE WERE RECALLS ON GEN 2 PRIUS'AND EXTENDED WARRANTY ON OTHER PRIUS' . THIS CAR FALLS UNDER NO HELP AT ALL. WE ARE ORIGINAL OWNERS AND CAR HAD BEEN ESSENTIALLY PROBLEM FREE. DISGUSTED THAT THIS DANGEROUS AND KNOWN PROBLEM ISN'T BEING PROPERLY ADDRESSED BY TOYOTA. ALL LIGHTS ON DASH RELATED TO BRAKES LIT UP WHILE DRIVING. STILL HAD BRAKES. TOOK TO DEALER TO CHECK PROBLEM.

A TIRE BLEW OUT ON THE HIGHWAY, AND AFTERWARDS THE ABS LIGHT, BRAKE LIGHT, AND TRACTION LIGHT CAME ON. APPARENTLY THE BRAKE ACUATOR HAS FAILED COMPLETELY.

I OWN A 2010 TOYOTA PRIUS IV. I CONCUR WITH ALL THAT HAS BEEN DOCUMENTED ABOUT ABS AND BRAKING ISSUES WITH THE PRIUS. TWO WEEKS AGO MY BRAKES STARTED TO SQEAL. I TOOK IT TO A MECHANIC AND WAS INFORMED ALL WAS WELL (BRAKE PADS,FLUIDS, OIL). A WEEK LATER THE BRAKE AND ABS INDICATOR CAME ON IN MY VEHICLE. THE BRAKING DISTANCE IS ELONGATED AS I HAVE TO PRESSED FIRMLY ON THE BRAKE FOR THE CAR TO STOP. I TOOK IT TO MY MECHANIC WHO RESET THE CAR. I DROVE FROM THE MECHANIC AND ALL APPEARED TO BE FINE UNTIL I HIT A BUMP IN THE ROAD. THE INDICATORS CAME BACK ON IMMEDIATELY AND THE BRAKING CHANGED. I HAD TO PRESSED THE BRAKE PEDAL ALL THE WAY DOWN IN ORDER FOR THE CAR TO START. THE CAR ALWAYS SURGES FORWARD WHENEVER I HIT A POTHOLE, BUMP OR ANY ROUGH SURFACE. IN HIN SIGHT, WHEN I FIRST BOUGHT THE CAR I HAD A FENDER BENDER BECAUSE THE CAR LURCHED FORWARD WHEN I WAS PARKING. I AM NOW DISCOVERING THIS ISSUE IS A KNWON ISSUED WITH TOYOTA; PARTICULARLY THE PRIUS. FIXING THIS PROBLEM SEEMS TO BE EXPENSIVE. TOYOTA SHOULD COVER THE COST VIA A RECALL.

ON A FEW OCCASIONS WHEN THE CAR IS IN MOTION, WE HAVE DEPRESSED THE BRAKES AND THEY DID NOT GRAB RIGHT AWAY. THIS HAPPENED ONCE GETTING ONTO A HIGHWAY, TWICE ON A CITY STREET, AND ANOTHER TIME ON A COUNTRY ROAD. THERE SEEMS TO BE A SMALL DELAY BEFORE THEY WILL GRAB, CAUSING THE CAR TO FEEL OUT OF CONTROL FOR THAT BRIEF MOMENT. IT FEELS UNSAFE WHEN THIS HAPPENS AND DOESN'T SEEM NORMAL. WE CONTACTED THE SERVICE MANAGER AT TOYOTA TO HAVE THE CAR LOOKED AT, AND HE DID NOT RETURN OUR CALL.

2010 TOYOTA PRIUS. CONSUMER WRITES IN REGARDS TO VEHICLE BRAKE DEFECT. *SMD *CN

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING VARIOUS SPEEDS, DEPRESSING THE BRAKE PEDAL TO COME TO A STOP, OR WHEN DRIVING OVER A BUMP, THE VEHICLE FAILED TO STOP. THE CONTACT STATED THAT THE VEHICLE STOPPED AFTER A DISTANCE, BUT NOT WHEN PROMPTED. ALL THE WARNING INDICATORS ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO GULLO TOYOTA OF CONROE (45 S, CONROE, TX 77304 ,(888) 483-0321) WHERE IT WAS DIAGNOSED THAT THE BRAKE ACTUATOR ASSEMBLY FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED DUE TO THE REPAIR FEES. THE MANUFACTURER INFORMED THE CONTACT THAT THE VIN WAS NOT INCLUDED IN A RECALL AND DID NOT OFFER FURTHER ASSISTANCE. THE APPROXIMATE FAILURE MILEAGE WAS 147,000.

VSC, BRAKE, AND ABS LIGHTS ARE ON SYMPTOMS: CRUISE CONTROL WILL BUMP UP THE SPEED THEN "CANCEL" CRUISE CONTROL THE ABILITY TO "SET" CRUISE IS REJECTED VSC, BRAKE, ABS LIGHTS TURN ON NO REGEN BRAKING BRAKES NEED WAY MORE EFFORT TO SLOW/STOP ABRUPT BRAKING WILL CAUSE A SKID ANY HELP WILL BE APPRECIATED.

AS MY WIFE WAS DRIVING THE BRAKES FAILED; THE PEDALS WENT TO THE FLOOR. SHE HAD TO SWERVE TO AVOID HITTING SOMEONE. SHE CONTINUE TO PRESS THE PEDALS AND THE CAR EVENTUALLY STOPPED. WHEN I GOT TO HER I TURNED THE CAR BACK ON AND TESTED THE BRAKES. THIS TIME THE PEDALS WOULD BARELY GO DOWN AND WOULD ONLY STOP THE VEHICLES IF YOU WENT 5 TO 10 MPH. IT RENDERED THE CAR UNUSABLE. I FOUND ONLINE THAT THERE WAS RECALL FOR 2010 TOYOTA PRIUS'S BUT TOYOTA SAID MY VIN WASN'T LISTED IN THE RECALL FOR AN ACTUATOR.

WHILE DRIVING ON HIGHWAY AT APPROXIMATELY 50MPH, INSTRUMENT CLUSTER DISPLAYED BRAKE, ABS, (!), AND TCS. AS I ATTEMPTED TO SLOW DOWN, BRAKES LOST EFFECTIVENESS AND BECAME MUSHY. I HAD TO PRESS ON BRAKE PEDAL EXTRA HARD TO SLOW THE CAR DOWN AND BRING TO CAR TO A STOP. PEDAL TRAVEL AND FORCE REQUIRED WAS WAY MORE THEN NORMAL.

ABS LIGHT STAYS ON, I HAVE NO BRAKES WHEN EMERGENCY BRAKING, THERE WAS A TOYOTA PRIUS RECALL ON BRAKE MASTER CYLINDER AND BOOSTER PUMP BUT TOYOTA SAID IT WAS NOT FOR MY VEHICLE. MY PROBLEM IS EXACTLY THE SAME PROBLEM AS OTHER PRIUS BRAKE RECALLS BUT TOYOTA WILL NOT COVER IT. LESS THEN 65,000 MILES ON THE CAR . HOW CAN A MASTER CYL BE BAD BY NOW, THEY USUALLY LAST OVER 100,000 MILES. VERY UNSAFE , AND MAY KILL SOMEONE. THIS SHOULD BE COVERED BY TOYOTA WITH ALL THE OTHER BRAKE RECALL PROBLEMS WITH THIS YEAR AND MODEL. I HAD TO SLAM ON MY BRAKES BUT MY CAR WOULD NOT STOP CAUSING ME TO RUN INTO A WALL AT THE BALTIMORE HARBOR TUNNEL. THIS IS A RECALL AND LETTERS WERE SENT OUT BY TOYOTA ABOUT THIS FAULTY BRAKING BUT NOW TOYOTA WILL NOT HONOR THE RECALL

MY CAR NEED TO REPLACE THE BRAKE PUMP ASSEMBLY WHICH IS SAME AS ONE OF THEIR PAST RECALL IN 2013. I CALLED TOYOTA AND THEY SAID MY CAR'S WAS NOT IN THE RANGE SO THEY DON'T COVER IT. YEA, CERTAIN VINS BUT IT IS CLEARLY THAT ALL THE 2010 PRIUS HAVE THIS ISSUE.

COPIED THE BELOW FROM ANOTHER COMPLAINT BECAUSE THIS GUY IS HAVING THE EXACT SAME ISSUE I AM HAVING, I BOUGHT THE CAR AUG 2017 RIGHT BEFORE THE PERIOD TO GET IT REPLACED EXPIRED, WAS NEVER NOTIFIED IN ANY WAY OF THIS WARRANTY CHANGE SO HOW AM I SUPPOSED TO KNOW I HAVE A DEFECTIVE PART ON MY CAR.. BUT THE DEALERSHIP STILL SOLD IT TO ME, NOW A MONTH AFTER THE ELIGIBILITY TO GET IT REPAIRED EXPIRES, MY BRAKES DIE AND TOYOTA SAYS THEY WONT HELP NOR IS THE DEALERSHIP RESPONSIBLE FOR SELLING ME THE CAR WITHOUT CHECKING IF THE RECALLED PART WAS REPLACED. THEY ALSO KEEP MENTIONING THE EXTENDED WARRANTY ON THE ACTUATOR IS ONLY FOR "CERTAIN VIN'S". SO THEY ARE GONNA EXTEND THE WARRANTY ON CERTAIN 2010 PRIUS' BUT NOT ALL OF THEM.. THIS MAKES NO SENSE.. PLEASE HELP MY 2010 PRIUS IS HAVING ISSUES AS SAME AS THE SAFETY RECALL BACK IN 2013 ( 13V-235 ). THE ABS LIGHT, VSC LIGHT, AND BRAKE LIGHT WERE ON AFTER A BUMPY ROOAD IN MY NEIGHBORHOOD. I BROUGHT IT TO THE DEALER AND THEY INDICATED THAT THERE WAS A LEAK IN THE ACCUMULATOR. AFTER RESET THE SYSTEM, ALL THE LIGHTS WENT OFF BUT I STILL FEEL THE LOSSES OF PRESSURE ON THE BRAKE PEDAL. HOWEVER, MY CAR HAS 0 OPEN RECALL AND THE DEALER QUOTED ME OVER 5K FOR THE REPAIR WHICH IS RIDICULOUS COMPARE TO THE VALUE OF THE CAR.

MY 2010 PRIUS IS HAVING ISSUES AS SAME AS THE SAFETY RECALL BACK IN 2013 ( 13V-235 ). THE ABS LIGHT, VSC LIGHT, AND BRAKE LIGHT WERE ON AFTER A BUMPY ROOAD IN MY NEIGHBORHOOD.

MY CAR HAD THE ABS WARNING LIGHT ON AND I HEARD A STRANGE NOISE IN THE ENGINE COMPARTMENT. LAST YEAR. ON OCTOBER 7, 2017, I WAS DRIVING ON THE HIGHWAY AND ANOTHER DRIVER CUT ME OFF, SO I HAD TO BREAK HARD. THE CAR PULLED HARD TO ONE SIDE AND I HIT THE RETAINING WALL. FORTUNATELY, THE DAMAGE TO THE CAR WAS ON THE BUMPER COVER ONLY, AND I WAS NOT INJURED, SO I WAS ABLE TO CONTINUE DRIVING. THE DEALER RAN DIAGNOSTICS ON MY CAR AFTER THE CRASH AND REPORTED I NEEDED TO HAVE CERTAIN PARTS REPLACED. TOYOTA SAFETY RECALL 13V-235 DESCRIBES EXACTLY THE SYMPTOMS MY CAR SHOWS AND REQUIRES REPLACEMENT OF EXACTLY THE SAME PARTS. THE ONLY PROBLEM IS THAT MY CAR'S VIN DOES NOT FALL IN THE RANGE TOYOTA REPORTED IN THE RECALL. APART FROM THAT , THE PROBLEM IS THE SAME. MY ACCIDENT COULD HAVE BEEN VERY SERIOUS HAD THE RETAINING WALL THAT STOPPED ME NOT BEEN THERE. I COULD HAVE BEEN IN THE CENTER LANES AND THE STORY WOULD HAVE BEEN VERY DIFFERENT, EVEN WITH ME SURVIVING THE ACCIDENT.

I NOTICED A 'CLICKING' IN MY BRAKES AND LOSS OF PRESSURE IN NOV. 2017. I TOOK IT TO A MECHANIC FRIEND TO LOOK IT OVER AND I WAS ADVISED THAT IT WAS THE BRAKE BOOSTER LEAKING AND I SHOULD TAKE IT TO THE DEALERSHIP BECAUSE THERE HAD BEEN A 'RECALL' SENT ON CERTAIN VIN #S BUT MINE WASN'T LISTED ON IT. WHEN I TOOK IT TO THE DEALERSHIP THEY WANTED TO CHARGE ME $700+ TO DIAGNOSE AND 'FIX' THE ISSUE. IT WAS NOT ON THE RECALL LIST BECAUSE OF THE PRODUCTION DATE OF MY CAR. I FOUGHT WITH TOYOTA CORP AND THEY DECIDED TO COVER THE COST AS A 'COURTESY'. THE CLICKING STOPPED FOR ABOUT 3 WEEKS THEN CAME BACK MUCH LOUDER AND MORE FREQUENTLY. STILL LOSING PRESSURE, ENOUGH SO THAT WHEN I WAS SITTING AT A STOP LIGHT I WOULD PUT THE CAR IN 'PARK' TO KEEP IT FROM MOVING FORWARD. AGAIN THE DEALERSHIP SAID THIS WAS NOT COVERED BY THE RECALL AND THIS TIME THE COST WOULD BE $4700+ TO 'FIX' THE ISSUE. THIS TIME THEY TOLD ME THEY CONFIRMED THE NITROGEN LEAK WITH THE 'BUBBLE TEST' SO IT WAS, IN FACT, THE BRAKE BOOSTER, BUT IT WAS STILL NOT COVERED. THIS TIME TOYOTA SAID THEY WOULD ONLY PAY $2000 FOR THE TOTAL COST, AGAIN AS A 'COURTESY', BUT I WOULD BE RESPONSIBLE FOR THE REMAINING AMOUNT. I ASKED THE DEALERSHIP IF THERE WAS SOMETHING I HAD DONE TO CAUSE THIS ISSUE AND I WAS TOLD 'NO'. TO ME THEN THAT IS A DEFECT FROM THE MANUFACTURER AND I SHOULD NOT BE RESPONSIBLE. I HAVE MAINTAINED THIS VEHICLE WITH THE DEALERSHIP ON A CONSISTENT BASIS, ALWAYS TAKING IT TO THEM FOR OIL CHANGES, ROTATIONS, ETC. ALWAYS ON THE SUGGESTED TIME SCHEDULE.

ON OCTOBER 7, 2017 A DRIVER CUT ME OFF ON THE HIGHWAY, I PRESSED MY BRAKES HARD AND THE VEHICLE PULLED TO THE SIDE AND I HIT THE RETAINING WALL. THE IMPACT WAS NOT TOO HARD AND I WAS ABLE TO CONTINUE TRAVELLING. THE ABS WARNING LIGHT IS ON AND I HEAR A STRANGE HUMMING NOISE UNDER THE HOOD. THE DEALER RAN DIAGNOSTICS AND SAID I NEEDED TO REPLACE TWO MAIN PARTS IN THE BRAKE SYSTEM. I FOUND A TOYOTA SAFETY RECALL 13V-235 AFFECTING OTHER PRIUS 2010 THAT DESCRIBES EXACTLY THE SAME PROBLEM AND REQUIRES REPLACEMENT OF EXACTLY THE SAME PARTS INDICATED IN THE SAFETY RECALL. THE ONLY PROBLEM IS THAT TOYOTA REPORTED THIS PROBLEM IN VEHICLES OF THE SAME YEAR AND MODEL, BUT MY CAR'S VIN WAS NOT INCLUDED IN THEIR INDICATED RANGE. THANK YOU FOR YOUR HELP

MY CAR HAD THE ABS WARNING LIGHT ON AND I HEARD A STRANGE NOISE IN THE ENGINE COMPARTMENT. LAST YEAR. ON OCTOBER 7, 2017, I WAS DRIVING ON THE HIGHWAY AND ANOTHER DRIVER CUT ME OFF, SO I HAD TO BREAK HARD. THE CAR PULLED HARD TO ONE SIDE AND I HIT THE RETAINING WALL. FORTUNATELY, THE DAMAGE TO THE CAR WAS ON THE BUMPER COVER ONLY, AND I WAS NOT INJURED, SO I WAS ABLE TO CONTINUE DRIVING.

I COULD HAVE BEEN IN THE CENTER LANES AND THE STORY WOULD HAVE BEEN VERY DIFFERENT, EVEN WITH ME SURVIVING THE ACCIDENT.

TURNING LEFT AFTER A STOP SIGN ON A SINGLE LANE STREET (30 MPH), SUDDENLY THE DASH BOARD STARTED FLASHING 'STOP CAR' WARNING AND CONTINUES BEEPING. ALSO, REALIZED THAT APPLYING BREAK PADDLE DID NOT HELP A BIT. IT WAS HARD TO PRESS THE PADDLE THAT MOVED A LITTLE BIT. GOING STRAIGHT ABOUT 300 FT. CAR REDUCED TO IDLING SPEED. TURNING LEFT INTO A PARKING LOT OF A SCHOOL, I TRIED STOPPING IT INTO A PARKING SPACE. BREAK DID NOT WORK AGAIN. SO, CAR STOPPED AFTER HITTING THE CURB. TOYOTA DEALERSHIP WAS CALLED AND ARRANGEMENTS WERE MADE TO TOW AWAY CAR FROM SCHOOL'S PARKING LOT. THE CAR DID NOT STOP WHEN TOWING PERSON TRIED TO REVERSE DRIVE. SOMEHOW HE MANAGED TO MANEUVER IT ON A TOW TRUCK. I WAS INFORMED BY DEALERSHIP THAT BREAK ASSIST SYSTEM (BAS), BUILT INTO PRIUS HYBRID MODEL, FAILED. THE SYSTEM COMPRISES OF ACCUMULATOR & PUMP THAT ASSISTS TO STOP THE CAR WHEN BREAK PADDLE IS PRESSED. THOUGH CAR WAS COVERED UNDER WARRANTY, BREAK SYSTEM AND ASSOCIATED COMPONENTS WERE NOT COVERED. REPAIR COST OVER $1900 TO REPLACE BAS. PURPOSE OF THIS COMPLAINT TO HIGHLIGHT NHTSA OF THE CRITICAL FAILURE OF PRIUS DESIGN TO ALLOW BREAK SYSTEM TO FAIL IN SUCH A COLOSSAL WAY. THE CAR COULD NOT BE STOPPED. THIS IS A SERIOUS DRIVING SAFETY CONCERN. ANY FAILURE OF BREAK ASSIST COMPONENT SHOULD NEVER EVER TAKE AWAY THIS CRITICAL CONTROL. INTENT OF THIS COMPLAINT IS FOR THE PUBLIC SAFETY, HAVING TOYOTA INFORMED OF THE INCIDENT. IT HAS BEEN VERY DISAPPOINTING THAT TOYOTA HAS NOT GIVEN ANY RESPONSE EXCEPT GIVING A CASE NUMBER BY A CUSTOMER SERVICE CENTER. REQUEST NHTSA TO LOOK INTO THE INCIDENT AND MOST IMPORTANTLY REVIEW DESIGN OF BREAK ASSIST SYSTEM FOR PRIUS IN THE INTEREST OF PUBLIC SAFETY AND DEFENSIVE DRIVING. PLEASE ADVISE SHOULD NHTSA REQUIRE FURTHER DETAILS OR INCIDENT NARRATIVE.

APPROACHING A STOP THE BRAKE PEDAL IN THE PRIUS WILL SUDDENLY LOSE RESISTANCE AND WILL NEED TO BE PUSHED TO THE FLOOR WHERE THE BRAKES WILL FINALLY ENGAGE AND THE AUTO WILL COME TO A HARD STOP. THIS HAPPENS RANDOMLY AND IS DIFFICULT FOR A MECHANIC TO DUPLICATE. I TOOK THE VEHICLE TO A TRUSTED MECHANIC (NOT THE TOYOTA DEALERSHIP) AND HE CONFIRMED IT IS AN HYDRAULIC PROBLEM AND THAT PADS/DRUMS/ETC. ARE OK. A RECALL WAS ISSUED FOR 2010 PRIUS'S DESCRIBING THIS EXACT SITUATION BUT MY VIN NUMBER WAS NOT INCLUDED IN THIS RECALL. RECALL DETAILS THE BRAKE BOOSTER PUMP CONTAINS A COMPARTMENT FILLED WITH NITROGEN GAS. THIS NITROGEN GAS CAN LEAK INTO THE BRAKE FLUID CAUSING REDUCED HYDRAULIC PRESSURE DURING APPLICATION OF THE BRAKES. REDUCED BRAKING EFFICIENCY CAN INCREASE THE RISK OF A CRASH. DEALERS WILL REPLACE THE BRAKE BOOSTER PUMP ASSEMBLY AS NECESSARY TO CORRECT THIS CONCERN. OUR QUICK TAKE REDUCED BRAKING PERFORMANCE MAY BE EXPERIENCED DUE TO A BRAKE BOOSTER SYSTEM ISSUE. WHAT SHOULD YOU DO? TOYOTA WILL BEGIN NOTIFYING OWNERS OF THE AFFECTED VEHICLES DURING JULY, 2013. IF YOU NOTICE PROBLEMS WITH THE BRAKING SYSTEM, OR YOU DON'T RECEIVE NOTIFICATION AND YOU FEEL YOU SHOULD HAVE, PLEASE CONTACT YOUR DEALER FOR FURTHER INSTRUCTION. THEY MAY ASK FOR YOUR VEHICLE IDENTIFICATION NUMBER (VIN), SO PLEASE HAVE IT HANDY WHEN YOU CALL. ON JAN 16, 2018 I CALLED MY LOCAL TOYOTA SERVICE DEPARTMENT AND WAS TOLD NOTHING COULD BE DONE AS I HAVE NO OUTSTANDING RECALLS ON THE VEHICLE. I THEN CALLED TOYOTA ON JAN 17 AND THEY TOLD ME MUCH THE SAME AND OPENED A CASE NUMBER FOR THE ISSUE. THIS ISSUE SEEMS TO BE COVERED ON NHTSA NUMBER 13V235000. I AM REQUESTING NHTSA ADVICE AS TO HOW TO PROCEED.

BRAKE LIGHTS CAME ON WHILE DRIVING ON FREEWAY. POWER BRAKES SEEMED TO FAIL AND A LARGE AMOUNT OF PRESSURE WAS REQUIRED TO STOP VEHICLE. TOYOTA OF FORT WORTH DEALERSHIP DIAGNOSED THAT THE ACTUATOR NEEDED TO BE REPLACED. WE PERFORMED REPAIR (AT A COST OF ROUGHLY $2,000.) A FEW DAYS LATER ON A LONGER DRIVE THE BRAKE LIGHTS TURNED BACK ON. WE RETURNED IT TO THE DEALERSHIP AND WERE TOLD THAT THE BRAKE BOOSTER/MASTER CYLINDER ASSEMBLY NEEDED TO BE REPLACED AT AN ADDITIONAL COST OF $2,900. I NOTICE THAT TOYOTA HAD A RECALL FOR THIS PART ON OTHER 2010 PRIUS VEHICLES BUT MY VEHICLE IS NOT INCLUDED IN THAT RECALL.

REFERENCE: TOYOTA PRIUS BRAKE BOOSTER PUMP ASSEMBLY RECALL 2013 THE 2013 RECALL WAS ISSUED FOR APPROXIMATELY 82,000 PRIUS VEHICLES MANUFACTURED FROM MARCH 2009 TO OCTOBER 2009. THE CAR I OWN AND OPERATE, ACCORDING TO A TOYOTA REPRESENTATIVE, WAS BUILT IN DECEMBER 2009 -- THUS, I PRESUME, DID NOT FIT WITHIN PARAMETERS OF THIS PARTICULAR RECALL. A TOYOTA CUSTOMER SERVICE REPRESENTATIVE SAID THAT THE VEHICLE MATCHING MY VIN NUMBER HAS NO SAFETY RECALLS ASSOCIATED WITH IT. HOWEVER, THE SAME ISSUE REFERENCED IN THE RECALL -- A FAULTY BRAKE PRESSURE ACCUMULATOR THAT COMPROMISES THE BRAKE BOOSTER PUMP ASSEMBLY SYSTEM -- APPEARS TO HAVE SURFACED IN MY 2010 PRIUS. NO ACCIDENT HAS OCCURRED. THE VEHICLE IS INDICATING A PROBLEM VIA ITS DASHBOARD WARNING LIGHTS. A TOYOTA MAINTENANCE TECHNICIAN, ON SEPT 21, 2017, DIAGNOSED THAT THE CAR'S BRAKE ACCUMULATOR PUMP IS MALFUNCTIONING -- AND THAT IT NEEDED TO BE REPLACED. I AM PETITIONING FOR CONSIDERATION TO EXPAND THE 2013 RECALL, WHICH WAS ORDERED TO CORRECT A DESIGN/MANUFACTURING DEFECT. THE SAME FLAW IS PRESENT IN MY VEHICLE (EVEN THOUGH MY VEHICLE WAS NOT COVERED BY THE ORIGINAL RECALL).

LEAK OF NITROGEN IS RELEASED INTO THE BRAKE FLUID, THE BRAKE PEDAL MAY HAVE REDUCED HYDRAULIC PRESSURE. UNDER CERTAIN CIRCUMSTANCES, THIS CONDITION COULD AFFECT STOPPING DISTANCE AND INCREASE THE RISK OF A CRASH.

MY 2010 PRIUS HAS HAD LIGHTS COME UP ON THE DASHBOARD. VSC, BRAKE, TRACTION & ABS. AFTER THE LOCAL TOYOTA DEALERSHIP RAN DIAGNOSTICS, IT CAME TO LIGHT THAT THE BRAKE ASSEMBLY WITH ACCUMULATOR WILL NEED TO BE REPLACED FOR NEAR $5,000. IT WOULD SEEM THAT THIS IS A COMMON PROBLEM THAT HAS RESULTED IN A RECALL FOR ONLY SOME OF THE 2010 PRIUS MODELS. MINE WAS NOT ONE OF THESE RECALLED. I WOULD LIKE TO REQUEST RECOGNITION THAT THIS SHOULD BE COVERED UNDER THE SAME RECALL. TOYOTA IS A GOOD PRODUCT, AND I UNDERSTAND THAT RECALLS ARE JUST A PART OF LIFE. AS IT STANDS, MY REGENERATIVE BRAKING NO LONGER WORKS AND I HAVE BEEN INFORMED THAT I WILL LOSE ALL BRAKING EVENTUALLY.

I WAS DRIVING TO MY HOUSE AND THE BRAKE PEDAL WENT TO THE BOTTOM. SEVERAL LIGHTS APPEARED ON THE DASHBOARD. I WAS DRIVING IN THE HIGHWAY AND FORTUNATELY THERE WAS AN EXIT AND I COULD GET OUT OF THE HIGHWAY AND I MANAGE HOW TO STOP AND I DID NOT CRASH. THE STORY COULD BE ANOTHER IF I WAS DRIVING FASTER. THE NEXT DAY I TOOK IT TO THE TOYOTA DEALER AND THEY TOLD ME THAT THE PROBLEM WAS THE BOOSTER PUMP (ATTACHED YOU CAN FIND THE ESTIMATE). I WAS SHOCKED WHEN I FOUND HOW MUCH WAS GOING TO COST ME. MY CAR HAS NEVER HAD A PROBLEM AND ALL OIL CHANGES HAD BEEN AT THE SAME TOYOTA DEALER. I HAVE NEVER TAKEN THE CAR ANYWHERE ELSE. INVESTIGATING I FOUND THAT THIS MODEL PRIUS 2010 IN 2013 HAD A RECALL FOR THIS SAME PROBLEM AFFECTING 82000 PEOPLE. UNFORTUNATELY, THE VIN NUMBER OF MY VEHICLE IS NOT IN THIS RANGE THAT REACHES A0067875 AND MINE IS A0205005. I NEED FOR TOYOTA TO EXTEND THE RECALL RANGE BECAUSE THE PROBLEM IS EXACTLY THE SAME AND ALSO HELP ME TO COVER THE COST OF THE REPAIR. AT THIS MOMENT, MY CAR IS PARKED AT HOME BECAUSE IS NOT DRIVABLE. I ALREADY SPOKE WITH TOYOTA HEADQUARTERS AND THEY SAID THAT THEY WILL NOT HELP ME WITH THE COST OF THE REPAIR, IT IS REALLY EXPENSIVE AND IT IS NOT MY FAULT. DOES TOYOTA HAVE TO WAIT UNTIL THERE IS AN ACCIDENT? OR INJURY OR DEAD PEOPLE?

DRIVING DOWN THE ROAD WHEN THE BRAKES WENT OUT. WARRANTY COVERAGE FROM TOYOTA ON THE SAME MODEL, MAKE, AND YEAR FOR THIS PROBLEM. MY VIN NOT INCLUDED IN THIS COVERAGE. THE BRAKE ACCUATOR ASSY IS THE ISSUE. HIGH DOLLAR REPAIR!!

I TOOK MY 2010 PRIUS IN FOR AIRBAG WORK & THEY ASKED HOW LONG I HAD BEEN DRIVING W/ MY BRAKE WARNING LIGHTS ON. THEY HAD NOT BEEN ON PRIOR TO THEN. THEY HOOKED UP A COMPUTER & SHOWED ME THAT THE VEHICLE HAD BEEN STARTED 31 TIMES SINCE THE WARNING WAS 1ST DETECTED. THEY SAID THERE WAS MOST LIKELY A LEAK IN THE BRAKE BOOSTER SYSTEM. THEY RESET THE WARNING, I DROVE FOR A DAY & IT CAME BACK ON AGAIN WHILE DRIVING AFTER ABOUT 10 STARTS. AFTER THE WARNING LIGHTS CAME ON AGAIN, I NOTED AN IMMEDIATE & SIGNIFICANT CHANGE IN BRAKING RESPONSIVENESS & VEHICLE CONTROL...STARTED PULLING TO THE RIGHT. THIS WAS ON THE HIGHWAY WHILE DRIVING STRAIGHT. I TOOK THE CAR IN TO A LOCAL TOYOTA DEALER FOR FULL DIAGNOSTIC & THEY SAID THAT THEY'RE WERE UNABLE TO LOCATE THE EXACT LEAK LOCATION, BUT THAT THEIR TECH ORDER SHOWS TO JUST REPLACE THE BOOSTER WHICH WILL COST ABOUT $3,300 O REPLACE.

BRAKE ACTUATOR FAILURE. COMPLETE LOSS OF POWER BRAKE FUNCTION WHILE DRIVING VEHICLE ON THE HIGHWAY. CURRENTLY A WARRANTY ENHANCEMENT LETTER COVERING THIS ISSUE, BUT ONLY UP TO 2009 MODEL PRIUS, I HAVE A 2010, NOT COVERED. THIS IS A HUGE SAFETY CONCERN AS IT HAPPENED WHILE DRIVING WITH NO INDICATION OF TROUBLE BEFOREHAND.

NO BRAKES. BRAKE PEDAL HARD TO PRESS. C1256 CODE FOUND. SEVERAL DIFFERENT LIGHTS ON DASHBOARD LIGHT UP PLUS BUZZER SOUND. BRAKE BOOSTER HAS GONE BAD. RECALL ON SAME MODEL/MAKE OF VEHICLE. BELIEVE PART TO BE DEFECTIVE. WENT FROM HAVING BRAKES TO LITTLE BRAKING CAPABILITY.

WHEN I GO OVER A PATCHED IN THE ROADWAY AND APPLY MY BRAKES MY CAR FEELS LIKE IT SKIPS.MOMENTARILY.. VEH.ICLE WAS IN MOTION.

SEVERAL BRAKE LIGHTS CAME ON THE DASH WHILE MY WIFE WAS DRIVING AND THE BRAKE PEDAL HAD A DIFFERENT SENSATION. SHE SAID IT STILL WORKED, BUT FELT VERY DIFFERENT - ENOUGH THAT SHE WOULD HAVE THOUGHT SOMETHING WAS WRONG EVEN IF THE LIGHTS HADN'T COME ON. I TOOK IT TO A LOCAL SHOP WHO SAID IT HAD TO GO TO DEALERSHIP. DEALER WANTED $3983 TO REPAIR SAYING THAT ABS ACCUMULATOR WAS BAD. IN DOING RESEARCH I DISCOVERED THAT MANY PRIUS' WERE RECALLED, BUT UNFORTUNATELY MY VIN WAS NOT INCLUDED IN THE RECALL. ALSO DISCOVERED THAT TOYOTA ISSUED AN "ENHANCED WARRANTY PROGRAM (ZG1) FOR MODELS 2004-2009. BUT MY NEWER MODEL (2010) IS NOT INCLUDED IN THE ENHANCED WARRANTY PROGRAM. IT FEELS LIKE TOYOTA KNOWS THEY HAVE A PROBLEM, BUT ARE NOT STANDING BEHIND THEIR VEHICLES. I CONTACTED TOYOTA CORPORATE CUSTOMER SERVICE AND SPOKE WITH TWO DIFFERENT INDIVIDUALS WHO CONFIRMED THAT BECAUSE MY VIN NUMBER DID NOT MATCH THE RECALLS, THERE WAS NOTHING TOYOTA WOULD DO FOR ME.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 5 MPH, THE BRAKE, ANTI-SKID, AND ABS WARNING INDICATORS ILLUMINATED. THE CONTACT KEPT DRIVING, BUT THE BRAKES LOCKED WHEN THE BRAKE PEDAL WAS DEPRESSED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THERE WAS A LEAK IN THE BRAKE ACCUMULATOR, AND THE BRAKE BOOSTER PUMP ASSEMBLY NEEDED REPLACEMENT. THE VEHICLE WAS NOT REPAIRED. THE CONTACT CALLED HIS INSURANCE COMPANY AND WAS INFORMED OF NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE CONTACT WAS ADVISED TO TAKE THE VEHICLE TO A TOYOTA DEALER. THE VEHICLE WAS TAKEN TO TEJAS TOYOTA (19011 HIGHWAY 59 N HUMBLE, TX 77338 (281) 446-0271) WHERE IT WAS ALSO DIAGNOSED WITH A LEAK IN THE BRAKE ACCUMULATOR AND THE BRAKE BOOSTER NEEDED REPLACEMENT. THE VIN WAS NOT INCLUDED IN THE RECALL. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND CONFIRMED THAT THE VIN WAS NOT INCLUDED IN THE RECALL. THE FAILURE MILEAGE WAS APPROXIMATELY 165,600.

SERIOUS BRAKE ISSUES! FAILURE OF BRAKE BOOSTER AND MASTER CYLINDER CAUSING IMPAIRED BRAKING LENDING TO SAFETY ISSUES. MANY INSIDERS AT TOYOTA KNOW THE 2010 PRIUS BRAKE ISSUES EXIST AND QUESTION WHY IT IS NOT HANDLED AT THE CORPORATE LEVEL. BRAKES ARE SPONGY AND ADDITIONAL PRESSURE MUST BE APPLIED. THE ABS IS INOPERABLE BECAUSE OF THE PROBLEM. PLEASE HOLD TOYOTA ACCOUNTABLE FOR THIS CHRONIC ISSUE. THE SAFETY OF ALL INVOLVED IS AFFECTED DUE TO INCONSISTENT BRAKING. MY DEALERSHIP ASKED CORPORATE TOYOTA TO ADDRESS AND THEY REFUSED.

BRAKE BOOSTER FAILURE.

THE BRAKES SEEM TO DISENGAGE FOR A SECOND AT RANDOM TIMES WHILE PRESSING ON THEM IN A NORMAL MANOR. I DRIVE EVERY DAY ABUT 20 MILES AND THIS SEEMS TO HAPPEN ABOUT ONCE A MONTH. I DIDN'T THINK MUCH OF IT UNTIL A FEW DAYS AGO WHEN I HAD TO SLAM ON MY BREAKS TO TRY AND AVOID AN ACCIDENT. DURING THAT INCIDENT THEY DISENGAGED FOR A SECOND AGAIN. THIS WAS A SECOND TOO LONG AND I WAS UNABLE TO AVOID A COLLISION. I LOOKED THIS UP AFTER MY ACCIDENT AND I SURPRISINGLY SAW SIMILAR REPORTS ON GOOGLE FOR MY CAR. BUT IT LOOKS LIKE TOYOTA IS SAYING THAT IT DOESN'T AFFECT MY VIN NUMBER? I'M HERE TO SAY THAT IT DOES.

I DRIVE A TOYOTA PRIUS 2010, I WAS DRIVING WHEN MY BRAKE, ABS, AND TRACTION CONTROL LIGHT CAME ON AT ONCE. WHEN I TRIED TO APPLY THE BRAKE IT WOULD TAKE A LOT OF FORCE FOR MY CAR TO STOP. I WENT TO THE TOYOTA DEALERSHIP TO GET IT CHECKED OUT AND THEY SAID PART NUMBER C1391 HAS TO BE REPLACED. TECH FOUND ABNORMAL LEAK IN ACCUMULATOR. THE ACCUMULATOR PUMP ASSEMBLY NEEDS TO BE REPLACED. WHICH WOULD COST ME 2,000 DOLLARS PARTS AND LABOR. THEY ALSO TOLD ME THEY MIGHT FIND OUT THAT THE MASTER CYLINDER MIGHT HAVE TO BE REPLACED AS WELL IF DAMAGED. WHICH WOULD BE 3,300 DOLLARS. SO WORST CASE SCENARIO IT WOULD BE OVER 5,000 WITH TAX TO FIX MY CAR. I NOTICED OTHER 2010 PRIUS MODELS WERE RECALLED FOR THE EXACT ISSUE BUT ONLY CERTAIN VIN NUMBERS. MY VIN NUMBER WASN'T INCLUDED. I FEEL LIKE IT SHOULD BE IF MANY OTHER PEOPLE ARE COMPLAINING ABOUT THE SAME ISSUE WITH THIS CAR. I CAN'T AFFORD OVER 2,000 IN REPAIRS LET ALONE 5,000.

BRAKE SLIPPING WHEN OVER THE MANHOLE AND LOST CONTROL EVEN NOT WET SURFACE. I INTENTIONALLY DROVE OVER SAME SPOT 4 TIMES ON 8/20/2017 AND EXACTLY SAME CONDITIONS HAPPEN.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 45 MPH, THE BRAKES OPERATED INDEPENDENTLY WHILE THE CONTACT WAS DEPRESSING THE ACCELERATOR PEDAL. THE VEHICLE WAS TAKEN TO JACK TAYLOR TOYOTA ON 3750 JEFFERSON DAVIS HWY, ALEXANDRIA, VA 22305 WHERE THE DIAGNOSIS WAS UNDETERMINED. THE CONTACT MENTIONED THE PRE COLLISION SYSTEM WAS DEACTIVATED HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 95,250.

TRAVELING STRAIGHT FORWARD AT 40 MPH AND APPROACHING A RED LIGHT. IMMEDIATELY UPON DEPRESSING THE BRAKE PEDAL, AN ALARM SOUNDED AND THE ABS, BRAKE, AND TRACTION CONTROL WARNING LAMPS LIT UP ON THE DASHBOARD, AND MY PRIUS COMPLETELY FAILED TO BRAKE, CONTINUING UNABATED TOWARD THE OTHER VEHICLES STOPPED AT THE RED LIGHT. I BEGAN PUMPING THE BRAKES AND WAS ABLE TO BUILD UP PRESSURE AND SAFELY STOP WITHOUT COLLISION OR FURTHER INCIDENT. MY LOCAL TOYOTA DEALER DIAGNOSED THE PROBLEM AS A "BRAKE ACCUMULATOR INTERNAL LEAK. RECOMMEND REPLACE BRAKE ACCUMULATOR". THIS NEEDS TO BE RECALLED, THIS IS EGREGIOUSLY IRRESPONSIBLE BY TOYOTA, I EASILY COULD HAVE BEEN HURT OR KILLED.

ABS BRAKE LIGHT STAYS ON ALL TIME.REAR WHEEL GETS EXTREMELY HOT,

I WAS DRIVING ON THE FREEWAY. ALL OF A SUDDEN BRAKE, ABS AND SUCTION TRACTION LIGHT TURNED ON. AFTER THAT I HAVE TO PUSH MY BRAKE HARDER TO SLOW DOWN THE VEHICLE. I WAS ABLE TO DRIVE IT BACK HOME SAFELY. I TOOK IT TO THE DEALER WHO SAID I NEED TO REPLACE BRAKE MASTER CYLINDER WITH BRAKE BOOSTER. DOING RESEARCH I FOUND MANY OWNERS OF THE SAME MODEL CAR HAVE SAME PROBLEM AND SOME OF THE CARS ARE RECALLED BUT NOT ALL. I BELIEVE MOST OF 2010 TOYOTA PRIUS CAR HAVE ISSUES WITH BRAKE SYSTEM WHICH IS BAD FOR OUR SAFETY. IT CAN CAUSE SERIOUS HARM FOR OUR SAFETY. I REQUEST YOUR GOOD DEPARTMENT TO INVESTIGATE THE BRAKING ISSUES FOR 2010 TOYOTA PRIUS VEHICLE. AS A GOOD CITIZEN OF THE COUNTRY, I FELT I NEED TO DISCUSS THIS ISSUE WITH YOU.

ABS AND BREAK LIGHT LIT WHILE GOING 55 MPH. LOST ANTILOCK BREAK FEATURE. LOCAL PORT ST LUCIE TIRE AND BREAK DIAGNOSED BAD MASTER CYLINDER AND NITROGEN LEAK INTO BREAK LINES. FOUND RECALL ON SIMILAR 2010 PRIUS' DUE TO NITROGEN LEAKAGE INTO BREAK LINES

ALL BRAKE LIGHTS COME ON (BRAKE, ABS AND TRACTION CONTROL) AND POWER ASSIST BREAKING STOPS WORKING AND BRAKES FEEL VERY WEAK. BRAKE ACTUATOR RUNS FREQUENTLY WHEN LIGHTS ARE NOT ON. THERE ARE MANY COMPLAINTS ONLINE AND TOYOTA CLAIMED THEY FIXED THIS ISSUE IN 2009 AND EXTENDED THE WARRANTY FOR 2009 AND EARLIER, BUT THE PROBLEM IS CLEARLY NOT FIXED.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE CONTACT'S WIFE WAS DRIVING 35 MPH, THE ABS, TRACTION CONTROL, AND BRAKE WARNING INDICATORS ILLUMINATED. THE DRIVER HAD TO APPLY EXTRA PRESSURE TO THE BRAKE PEDAL TO SLOW DOWN THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE BRAKE BOOSTER AND MASTER CYLINDER FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THE VEHICLE WAS NOT WITHIN THE VIN RANGE. THE APPROXIMATE FAILURE MILEAGE WAS 95,000.

ABS LIGHT CAME ON. DIAG CODE: C1391. ABNORMAL LEAK IN ACCUMULATOR. THIS PROBLEM IS SIMILAR TO A RECALL ON PRIUS 2010 FOR ABS BRAKE ISSUE. HOWEVER, TOYOTA SAID THAT MY PRIUS IS NOT PART OF THE RECALL. I WOULD LIKE TO REQUEST TOYOTA TO FIX THIS PROBLEM FOR MY PRIUS 2010 SO THAT I CAN SAFELY DRIVE THIS CAR.

BRAKES TURNED TO MUSH - PEDAL WENT ALL THE WAY TO THE FLOOR WITH ALMOST ZERO STOPPING POWER. SOUNDS LIKE A SIMILAR RECALL FROM 2013 OR SO. GOING 45 MPH (SPEED LIMIT) ON A BUSY 4 LANE HGHWAY APPROACHING STOPLIGHT AND SLOWING TRAFFIC FOR RED LIGHT AT INTERSECTION OF ANOTHER 4 LANE ROAD. BRAKES MOSTLY UNRESPONSIVE. ALMOST WENT THROUGH INTERSECTION AND NARROWLY MISSED HITTING A SLOWING CAR. BRAKING DID NOT ENGAGE PER USUAL ACTIVATION POSITION AND PEDAL WENT TO THE FLOOR INSTEAD. CAR WAS JUST SERVICED A WEEK AGO FOR UNRELATED RECALL ITEM. CAR HAS BEEN MAINTAINED DILIGENTLY SINCE NEW PURCHASE IN 2009, GETTING ALL RECALLS SERVICED PROMPTLY. MAYBE THE RANGE OF VINS IN THE OLDER RECALL WAS NOT WIDE ENOUGH?

WHEN DRIVING OVER BUMPY OR ROUGH SURFACES OR POT HOLES, WHILE APPLYING THE BRAKES, THE BRAKES OFTEN SEEM TO STOP WORKING. AND THE CAR SEEMS TO HAVE A LITTLE BOOST FORWARD. IT HAPPENS WHEREVER THE ROAD SURFACE HAS BUMPY AREAS ON STRAIGHTAWAYS OR CURVES. AND MOSTLY WHEN APPLYING LIGHT PRESSURE TO THE BREAK, LIKE SLOWING FOR AN UPCOMING TURN. IT HAS BEEN HAPPENING SINCE I GOT THE CAR IN 2013. I HAVE TAKEN IT TO A MECHANIC, BUT THEY COULDN'T FIND THE PROBLEM. THIS HAS HAPPENED MANY TIMES OVER LAST 3 1/2 YEARS.

I AM THE ORIGINAL OWNER OF A 2010 PRIUS. WITHIN THE FIRST MONTH, I CONTACTED TOYOTA, COMPLAINING OF THE BRAKES, WHICH WERE NOT CONSISTENTLY SMOOTH. IN GENERAL, THE BRAKES WORK FINE, BUT IF I HIT A BUMP OR DITCH, THE BRAKES SUDDENLY STOP WORKING FOR A SPLIT SECOND, AND THE CAR FEELS LIKE IT IS LURCHING FORWARD, BEFORE THE BRAKES SUDDENLY START WORKING AGAIN. TOYOTA SERVICE WAS NEVER ABLE TO "REPRODUCE" THE PROBLEM, AND EVENTUALLY I GAVE UP. A COUPLE YEARS AGO, THE CAR WAS RECALLED FOR THIS PROBLEM, AND I BROUGHT THE CAR IN TO BE FIXED. UNFORTUNATELY, THE RECALL WORK HAS NOT REMEDIED THE PROBLEM. THE BRAKES STILL SEEM TO OCCASIONALLY MALFUNCTION WHEN THE CAR DRIVES OVER A ROUGH PATCH. TOYOTA SEEMS TO BELIEVE THE PROBLEM HAS BEEN SOLVED, BUT IT HAS NOT BE SOLVED. THERE IS NO DIFFERENCE SINCE THE RECALL.

THIS AFTERNOON, MY WIFE WAS DRIVING DOWN A TWO LANE, PAVED STREET AT ABOUT 25 MPH. THE STREET HAS A SLIGHT DECLINE AND SHE BEGAN TO APPLY THE BREAKS TO SLOW DOWN SLIGHTLY. JUST A SECOND OR TWO LATER, SHE HIT A SMALL BUMP IN THE ROAD AND THE CAR ACCELERATED (WHILE SHE HAD HER FOOT ON THE BREAK) FOR A FRACTION OF A SECOND. WE DIDN'T HEAR THE SOUND OF THE ENGINE REVVING. THANKFULLY, THERE WERE NO OTHER CARS ON THE ROAD AT THIS TIME AND THERE WAS TIME TO PRESS THE BREAK AGAIN. BASED ON LOOKING AROUND ONLINE, MANY PEOPLE HAVE REPORTED SIMILAR ISSUES (HTTP://WWW.CONSUMERREPORTS.ORG/CRO/NEWS/2010/02/TOYOTA-ADDS-2010-PRIUS-BRAKING-PROBLEM-TO-THE-LIST-RECALL-POSSIBLE/INDEX.HTM).

ABS ACTUATOR WITH MASTER CYLINDER ASSEMBLY HAS INTERNAL LEAK. ASSEMBLY DOESN'T HOLD PRESSURE AND ACTUATOR MOTOR CONTINIOUSLY WORKING IN ORDER TO CREATE THE PRESSURE. DUE TO THIS PROBLEM BRAKES ARE NOT OPERATE AS PROPERLY. IT TAKES MORE STRENGTH TO PUT ON THE PEDAL TO STOP VEHICLE. I ALSO NOTICED THAT DURING EMERGENCY BRAKING NOT ALL WHEELS WERE INVOLVED EQUALLY. DUE TO THIS PROBLEM BRAKING DISTANCE SIGNIFICANTLY INCREASED. I HAVE 3 INSTRUMENT CLUSTER ERROR LIGHTS TURNED ON DUE TO THIS PROBLEM: "BRAKE", LIGHT WITH VEHICLE ON SLEEPY ROAD, AND LIGHT WITH "!" SIGN. I FOUND THAT THERE ALREADY WAS RECALL FOR SAME 2010 YEAR TOYOTA PRIUS UNDER TMS-NTC-13178 OF JULY 23, 2013, TOYOTA RECALL NAME D0H, BUT MY VEHICLE IS NOT COVERED. I KINDLY ASK YOU TO INVESTIGATE IF MY CAR ELIGIBLE TO PARTICIPATE IN THIS RECALL CAMPAIGN, SINCE SEEMSTHAT THIS CAR WERE ASSEMBLED WITH SAME UNRELIABLE PARTS.

THE BRAKE ACTUATOR FAILED ON OUR 2010 PRIUS III MANUFACTURED IN OCTOBER 2010. TOYOTA IS COVERING PROBLEMS WITH THIS SAME BRAKE ACTUATOR FOR 2010 PRIUS MANUFACTURED BETWEEN MARCH 2009 AND EARLY OCTOBER 2009. MY VIN DID NOT FALL INTO THAT DATE RANGE EVEN THOUGH MINE WAS MANUFACTURED IN OCTOBER 2009, SO THE BRAKE DEFECT SHOULD BE EXTENDED TO BEYOND THE EARLY OCTOBER 2009 MANUFACTURED DATE. THE SYMPTOMS TO THIS PROBLEM WERE THE BRAKE, ABS AND TRACTION CONTROL WARNING LIGHTS CAME ON, NO REGENERATIVE BRAKING AND THE BRAKING DISTANCE INCREASED.

THE BRAKE BOOSTER PUMP ASSEMBLY FAILED, WHICH LEFT ME WITH NO BRAKES AND IN A LIFE-THREATENING SITUATION. THE VEHICLE WAS IN MOTION AND I NARROWLY AVOIDED A BAD ACCIDENT ON A CITY STREET.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 20 MPH, THE BRAKED PEDAL WAS DEPRESSED AND FAILED TO OPERATE AS INTENDED. THE CONTACT STATED THAT SEVERAL WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE BRAKE BOOSTER PUMP FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

ABS + BREAKS + TCS LIGHTS ARE ON AND MY CAR'S BREAKS ARE NOT WORKING IT WAS ABOUT TO HIT WITH NEXT CAR BUT MY SPEED WAS UNDER 30 THAT'S WHY I REACHED SAFELY. I SHOWED IT TO JUST BREAK AND THEY SAID IT'S REQUIRED ECU UPDATE. IT'S A SOFTWARE PROBLEM IN THIS MODEL. I DON'T KNOW HOW TO UPDATE SOFTWARE. IS IT POSSIBLE IF I GET FREE UPDATE FROM TOYOTA DEALERSHIP ?

TL* THE CONTACTS OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKES TRAVELED TO THE FLOOR WHEN THE BRAKE PEDAL WAS DEPRESSED AND THE VEHICLE DID NOT DECELERATE NORMALLY. THE DEALER DIAGNOSED THAT THE ACTUATOR SYSTEM NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 92,514.

MY WIFE WAS DRIVING ON THE HIGHWAY WHEN HER BRAKES TOTALLY FAILED. SHE APPLIED BRAKE PRESSURE AS HARD AS SHE COULD, BUT IT HAD NOT EFFECT. FORTUNATELY, SINCE SHE WAS IN THE LEFT LANE OF THE INTERSTATE HIGHWAY, SHE WAS ABLE TO COAST TO A STOP IN THE LEFT HAND SHOULDER. SEVERAL RED LIGHTS LIT UP ON THE DASHBOARD, INCLUDING THE BRAKE AND ABS LIGHTS. I HAD THE CAR TOWED TO WORLD TOYOTA DEALERSHIP IN ATLANTA. THEY SAID THE BRAKE MASTER CYLINDER FAILED. I PAID THEM TO FIX IT. SEE ATTACHED WORK ORDER FROM WORLD TOYOTA. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKE PEDAL WAS APPLIED SEVERAL TIMES AND THERE WAS AN ABNORMAL NOISE AND VIBRATION. THE VEHICLE FAILED TO COME TO A COMPLETE STOP. THE CONTACT HAD TO APPLY FORCE TO THE BRAKE PEDAL, BUT THE FAILURE CONTINUED. THE DEALER WAS NOTIFIED SEVERAL TIMES, BUT WAS UNABLE TO REPLICATE AND DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOTIFIED. THE VIN AND FAILURE MILEAGE WERE NOT AVAILABLE.

I APPLIED BRAKE ON A RED LIGHT WHICH IS AS USUAL FOR ME AND I NOTICED CAR DIDN'T SLOW DOWN AND KEPT MOVING PAST THE RED LIGHT. IT HAS HAPPENED BEFORE AND THE IT HAPPENS ON UNEVEN AND EVEN ON MINOR POTHOLES. THE BRAKES ON THE SMALL BUMPS AND MINOR UNEVEN ROADS COMPLETELY LOOSE TRACTION OF THE TIRES AND CAR EVEN FASTER WITH THE BRAKES ON WHEN TRYING TO STOP OVER MINOR UNEVEN ROADS. MECHANIC SAID IT'S OVERSENSITIVE ANTI LOCKING BRAKES THAT CUT OFF THE BRAKE POWER EVEN WHEN IT DETECTS MINOR DISTURBANCE IN THE SENSORS. *TR

I HAVE A 2010 TOYOTA PRIUS. WHEN TRYING TO SLOW DOWN, ANY TIME A BUMP IS HIT, (OR A POTHOLE) THE BRAKING POWER SIGNIFICANT DECREASES . THIS GREATLY INCREASES THE STOPPING DISTANCE AND IS VERY SCARY IN TRAFFIC AND IN WINTER DRIVING. IS THIS A PROBLEM? I CALLED TOYOTA EARLIER FOR THE SAME ISSUE AND THEY TOLD ME THAT THIS IS NORMAL AND THIS OCCURS BECAUSE ONLY ONE TIRE IS HITTING THE POTHOLE OR BUMP' IT IS VERY SCARY AND I HAVE TO LEAVE A LOT OF SPACE AHEAD OF MY CAR.

I RECENTLY PURCHASED A TOYOTA 2010 PRIUS AND FOUR DASH WARNING LIGHTS APPEARED THE DAY AFTER I PURCHASED IT WHEN I TURNED THE CAR ON IN THE MORNING. THE LIGHTS STAY ON FOR HOURS TO DAYS AND GO OFF FOR SIMILAR AMOUNT OF TIME. WHEN THE LIGHTS ARE ON THE BRAKES ARE MUCH LESS RESPONSIVE AND THE BRAKING ACTION DOES NOT CHARGE THE BATTERIES AS MUCH, NEVER MORE THAN 25% OF CHARGING POTENTIAL. THE PROBLEM WAS DIAGNOSED AS A PROBLEM WITH ACCUMULATOR IN THE BRAKE SYSTEM. I PERFORMED A SEARCH ONLINE AND FOUND THAT THERE IS A RECALL FOR SUCH PROBLEM, BUT MY VEHICLE WAS PRODUCED A MONTH AFTER THE DATE OF PRODUCTION THAT WOULD QUALIFY FOR THIS RECALL. I WILL A PDF COPY OF THE RECALL I'M REFERRING TO.

HELLO. I RECENTLY STARTED TO EXPERIENCE AN ISSUE WITH MY VEHICLE. MY BRAKES STARTED TO MAKE SOME KIND OF UNUSUAL NOISES EVERY TIME I PRESS ON THEM. I'VE NEVER HAD THAT BEFORE AND I SERVICE MY CAR PRETTY OFTEN. I WENT TO AUTHORIZED TOYOTA DEALERSHIP AND THEY TOLD ME THERE WAS A COMPUTER ISSUE AND THEY FIXED IT FOR $110. IT CONTINUED TO MAKE NOISES AND ALL OF THE SUDDEN IT BEGAN SHOWING ABS/BRAKE/VSC LIGHTS ON MY CAR DASHBOARD EITHER WHILE I WAS DRIVING OR BEING IN THE 'PARK' MODE. AT THE SAME TIME MY BRAKES STOPPED WORKING WELL WHILE DRIVING WHEN THE ABS/BRAKE/VSC LIGHTS WERE ON. I CHECKED THE CODE OF THE ERROR THROUGH THE CAR COMPUTER AND IT SHOWED ME 'C1391'. I WENT TO THE DEALERSHIP AGAIN AND THEY DID ANOTHER CHECK AND THIS TIME THEY FOUND THAT BRAKE MASTER CYLINDER/BOOSTER/ABS ASSEMBLY NEEDS TO BE REPLACED WITH $3,170 PRICE. I ATTACHED HERE THE PAPER THAT MY TOYOTA PRIME DEALERSHIP LOCATED HERE IN SACO, ME GAVE ME. I'VE BEEN READING A LOT ABOUT IT ONLINE AND PEOPLE WITH THE SAME TYPE OF HYBRID VEHICLES HAVE EXPERIENCED IT. I THINK TOYOTA NEEDS TO LOOK INTO THE ISSUE AND ACKNOWLEDGE THAT IT IS A COMMON PROBLEM IN THEIR HYBRID VEHICLES. I SERVICE MY CAR ALL THE TIME, I DO OIL CHANGE AND CHECK ALL THE SYSTEMS VERY THOROUGHLY, SO I DON'T UNDERSTAND WHY WE, CONSUMERS, HAVE TO PAY THAT BIG OF A PRICE FOR THE CAR REPAIR. I HOPE YOU CAN LOOK INTO THE ISSUE AND HELP ME (AND TO ALL OTHER CAR OWNERS) TO RESOLVE THIS KIND OF ISSUE. THANK YOU.

COMPLETE BRAKE FAILURE WHEN STOPPING FOR STOPLIGHT ON HWY 53/MIDWAY ROAD. RESULTING IN 3 CAR ACCIDENT. THIS WAS THE SECOND BRAKE FAILURE. THE FIRST COMPLETE BRAKE FAILURE HAPPENED WHEN BACKING OUT OF PARKING SPACE AT WORK LOCATION. BRAKES WERE PRESSED , CAR KEPT BACKING UP HITTING A PARKED CAR BEHIND US. AFTER THE FIRST FAILURE THE LOCAL TOYOTA DEALERSHIP DROVE THE CAR AND ALSO EXPERIENCED TOTAL BRAKE LOSS AFTER DRIVING IT FOR A BIT. THE TOYOTA DEALERSHIP REPLACE THE BRAKE CYLINDER ASSEMBLY. *TR

I WENT TO START THE PRIUS AFTER WORK, AFTER I PRESSED THE START BUTTON, SEVERAL ALARMS WENT OFF ON THE MAIN PANEL. ALARMS INCLUDED THE MASTER ALARM, ABS, BRAKE, CHECK ENGINE, AND AN INCESSANT BEEPING. THERE WAS ALSO A REPETITIVE SOUND COMING FROM UNDER THE HOOD THAT SOUNDED LIKE THE BRAKING SYSTEM WAS TRYING TO BUILD PRESSURE, BUT WAS NOT SUCCESSFUL. I TOWED THE VEHICLE TO THE DEALERSHIP AND THEY DIAGNOSED THIS AS THE MASTER BRAKE BOOSTER ASSEMBLY. THE QUOTE WAS $2500 FOR THE PART, AND $500 IN LABOR. THEY STARTED WORK ON THE VEHICLE, THEN CALLED AND SAID THAT THEY WOULD HAVE TO REPLACE THE ACCUMULATOR AS WELL, EVEN THOUGH IT WAS ALREADY REPLACED DURING THE ORIGINAL RECALL. THEY CONTACTED TOYOTA CORPORATE WHO PAID FOR THE ACCUMULATOR, BUT WOULD NOT COVER THE ADDITIONAL LABOR TO INSTALL THE ACCUMULATOR. THE TOTAL BILL WAS $3900. THIS SEEMS LIKE A COMMON PROBLEM WITH THE PRIUS FAMILY. MY CAR HAD APPROXIMATELY 92,000 MILES.

BRAKE SYSTEM FAILURE WHILE DRIVING ON SUBURBAN STREET. MASTER CYLINDER, ASSEMBLY AND BOOSTER REPLACEMENT. ALL CORRESPONDING WARNING CAME ON. WAS ABLE TO DRIVE TO DEALER. THIS IS THE EXACT PROBLEM THAT INCITED THE RECALL FOR NITROGEN LEAKING INTO THE BRAKE SYSTEM IN SOME PRIUS MADE IN 2010 (82,000). COST OF $3200. INCIDENTALLY, BRAKE FLUID WAS FLUSHED AND CHANGED AT 60,000 AND THEN AGAIN AT 75,000. THE REASON, STATED FROM THE DEALER IS THAT MAINTENANCE WAS RESPONSIBLE FOR THE FAILURE. PRIORITY TOYOTA OF SPRINGFIELD WAS THE ONLY ONE DURING THE MAINTENANCE AND I FOLLOWED THEIR RECOMMENDED ADVICE FOR THE 2 BRAKE FLUID FLUSHES AND REPLACEMENT.

WE CAME TO THE DEALERSHIP AT AUBURN BLVD AND THEY TOLD US THEY DON'T HAVE A PARTS FOR RECAL AND IT WILL TAKE ABOUT A WEEK TO ORDER THEM . THEY GAVE US A PAPER STATING THAT THE RECAL HAS BEEN FIXED FOR DMV PURPOSES TO RENEW THE REGISTRATION EVEN THOUGH RECAL WASN'T FIXED. IT HAS BEEN MORE THEN 4 MONTHS AND NO ONE FROM DEALERSHIP CALLED US TO INFORM US WHEN THEY'LL ACTUALLY FIX THE RECALLED PART. EVERY TIME I CALL THEM THEY SAY THEY DON'T HAVE PART IN STOCK AND THEY DON'T KNOW WHEN THEY'LL RECEIVE IT. PLEASE HELP!

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKE PEDAL REQUIRED TO BE DEPRESSED SEVERAL TIMES IN ORDER FOR THE VEHICLE TO COME TO A STOP. THE ABS, THE TRACTION CONTROL, AND THE BRAKE WARNING INDICATORS ILLUMINATED. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 159,000.

I AM EXPERIENCING A RESURGENCE OF THE ACCELERATION WHILE BRAKING PHENOMENON THAT WAS THE BASIS OF THE 2010 RECALL. WE HAD THE CAR FIXED AT THE TIME OF THE RECALL. THE INCIDENTS RELATE TO WHEN I AM BRAKING AND HAPPEN TO GO OVER A BUMP OR HIT A POTHOLE. AS I AM BREAKING THE CAR SUDDENLY ACCELERATES FORWARD AND YOU HAVE TO KEEP BREAKING HARDER TO KEEP FROM HAVING THE CAR GET AWAY FROM YOU. IT IS NOW HAPPENING ALMOST CONSISTENTLY. AFTER CALLING THE LOCAL TOYOTA DEALER AND THE GENERAL TOYOTA NUMBER, I FIND OUT THAT THEY ARE NOT WILLING TO APPLY THE SAME FIX AS THEY DID IN 2010. I AM NOW FORCED TO TAKE THE CAR IN AND HAVE IT DIAGNOSED AND DON'T KNOW WHAT THEY WILL CHARGE ME FOR THAT. THEN TOYOTA SAID I COULD CALL THEM BACK TO SEE IF THERE IS ANYTHING THEY CAN DO I DON'T UNDERSTAND WHY THEY DON'T HAVE TO STAND BY A FIX THAT IS NOT RELATED TO WEAR AND TEAR BUT RATHER A MALFUNCTION IN THE WAY THEY BUILT THE CAR. IT SHOULD NEVER BE RIGHT TO HAVE A CAR ACCELERATE IF ONE IS BRAKING. THE ONLY DAMAGE TO DATE HAS BEEN A GLARE FROM A CONSTRUCTION WORKER WHO WAS TELLING ME TO STOP ONLY TO SEE THE CAR LURCH TOWARD HIM.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 30 MPH, THE BRAKE PEDAL WAS DEPRESSED BUT THE VEHICLE FAILED TO SLOW DOWN UNTIL EXCESSIVE PRESSURE WAS APPLIED.

DESIGN FLAW....LOSS OF BRAKE FUNCTION DURING BRAKING EVENTS WHILE GOING OVER BUMPS AND POTHOLES (LOWER SPEEDS <30MPH). I BELIEVE THE ROOT CAUSE IS THE TRANSITION BETWEEN REGENERATIVE BRAKING AND HYDRAULIC BRAKE. I ALWAYS FEEL UNSAFE DURING BRAKING EVENTS, AND ALWAYS HAVE TO BE PROACTIVE AND CALCULATE THE DISTANCE IN FRONT OF ME TO ACCOMMODATE THE LOSS IN STOP DISTANCE . VERY UNCOMFORTABLE FEELING!

BRAKES SUDDENLY STOPPED FUNCTIONING WHILE DRIVING 55 MPH ON 4 LANE HIGHWAY. DASHBOARD ALARMS ALSO INDICATED THERE WAS A BRAKE PROBLEM. PER TOYOTA TECHNICIAN AT PRESTIGE TOYOTA IN KINGSTON NY, GAS BUBBLES CONTAMINATED BRAKES AND RUINED PUMP AND ACTUATOR. ACCORDING TO TOYOTA WARRANTY ASSISTANCE REPRESENTATIVE "FRED," WHO SPOKE WITH LOCAL TECHNICIAN, THERE WAS A RECALL FOR THIS EXACT CONDITION, BUT DID NOT INCLUDE MY PARTICULAR VIN. I WAS VERY LUCKY NOT TO HAVE BEEN IN A SERIOUS ACCIDENT, AND I HAVE TO WONDER HOW MANY OTHER PRIUS DRIVERS ARE AT SERIOUS RISK BECAUSE OF SIMILAR CONDITION.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT AN UNKNOWN SPEED, THE BRAKE PEDAL WAS DEPRESSED BUT IT TOOK A GREATER AMOUNT OF TIME TO STOP THE VEHICLE.

THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS INCLUDED IN NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE FAILURE MILEAGE WAS 96,000.

ONCOMING CAR STOPPED AT TRAFFIC LIGHT WHILE I WAS PROCEEDING STRAIGHT IN THE OPPOSITE DIRECTION. THE ONCOMING CAR THEN MADE A LEFT TURN ACROSS THE ROAD IN FRONT OF ME. I STARTED A TURN TO THE RIGHT ASSUMING THAT THE OTHER CAR WOULD SEE ME AND STOP. AT THE SAME TIME I HIT MY BRAKES. MY CAR SEEMED VERY SLOW TO DECELERATE. I NOW REALIZE THAT CAR BRAKES CAN GIVE MUCH MORE SIGNIFICANT STOPPING. AT THE TIME, BECAUSE OF MY TRAINING AS MILITARY AND AIRLINE PILOT, I STAYED ON THE BRAKES AND DID NOT PUMP THEM. IN RETROSPECT, PUMPING THE BRAKES MIGHT HAVE GOTTEN THEM TO WORK. THE ANTI-SKID SYSTEM SEEMED TO BE INEFFECTIVE. I STRUCK THE OTHER CAR AT ITS RIGHT FRONT WHEEL. MY AIRBAG WORKED WONDERFULLY, BUT MY CAR WAS TOTALED. AS NO PERSON WAS HURT, THE POLICE WERE UNINTERESTED. THE ACCIDENT IS ON FILE WITH RIVERSIDE COUNTY SHERIFF'S OFFICE AS FILE# MV142810251. THE DATE WAS 10-8-2014.

AT 46,900 MILES WITHOUT ANY WARNING ALL THE BRAKE WARNING LIGHTS CAME ON AND BRAKING EFFECTIVENESS DROPPED OFF. HAVE TO PUSH PEDAL TO THE FLOOR TO GET THE CAR TO STOP THE LIGHTS FOR TRACTION CONTROL, ANTI LOCK BRAKES AND THE WORD "BRAKE" AND ANOTHER LIGHT LIKE A CIRCLE ARE ON ALL THE TIME NORMALLY THERE IS STRONG BRAKING WHEN FIRST TOUCH THE BRAKE PEDAL BUT NOW VERY LIMITED BRAKING UNTIL PUSH DOWN VERY HARD ON THE BRAKE PEDAL. LOOKED AT BRAKE FLUID AND IT IS FULL, DO NOT KNOW WHY THE BRAKES ARE NOT WORKING

UPDATED 09/06/16*LJ THE CONSUMER STATED THE MASTER CYLINDER/BRAKE BOOSTER ASSEMBLY WERE SUBSEQUENTLY REPLACED. ALSO, ON JANUARY 5, 2016, THE CONSUMER WAS INVOLVED IN AN ACCIDENT WHILE DRIVING ON A WINDING HIGHWAY. AS HE TRIED TO NEGOTIATE A TURN, THE TIRES SLIPPED OFF THE PAVEMENT AND HE RAN OFF THE ROAD, CAUSING OVER $10,000 IN DAMAGES. UPDATED 10/18/16. *JB

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 35 MPH OVER BUMPS IN THE ROAD, THE BRAKES FAILED TO SLOW DOWN THE VEHICLE. THE FAILURE RECURRED EACH TIME THE VEHICLE DROVE OVER A BUMP.

WHILE DRIVING HOME FROM WORK, THE BRAKES WENT OUT ON MY TOYOTA PRIUS AND THE WARNING LIGHTS FOR ABS, TRACTION CONTROL, AND BRAKES ALL CAME ON. I STILL HAD A SMALL AMOUNT OF BRAKE PEDAL LEFT AND THE EMERGENCY BRAKE CONTINUED TO WORK. WHEN THE TOYOTA DEALER DIAGNOSED THE PROBLEM TODAY, THEY SAID THAT IT WAS A $3500 BRAKE BOOSTER AND THAT IT WAS NOT COVERED UNDER RECALL OR WARRANTY. THE SYMPTOMS, THE WARNING LIGHTS, AND THE RESULTS ALL MATCH A PREVIOUS TOYOTA RECALL (D0H) EXACTLY, YET THEY WILL NOT INCLUDE MY CAR UNDER THE RECALL BECAUSE MY VIN IS NOT PART OF THE ORIGINAL RECALL. THEY'RE LUCKY I WASN'T PHYSICALLY INJURED IN ACCIDENT CAUSED BY THIS. I SUGGESTED TO THEIR CUSTOMER SERVICE REP THAT MAYBE MY CAR SHOULD BE INCLUDED IN THE RECALL, BUT THEY DID NOT AGREE.

I WAS DRIVING MY VEHICLE AT ABOUT 35 MPH ON A TWO LANE, HILLY ROAD. SUDDENLY, THE ABS AND WARNING LIGHTS STARTED FLASHING, AND THERE WAS A LOUD BEEPING NOISE. I PRESSED THE BRAKE PEDAL, AND THERE WAS NO RESPONSE. SINCE I WAS TRAVELING UPHILL, I SLOWED AND THEN USED MY EMERGENCY BRAKE TO COME TO A COMPLETE STOP. AFTER THE VEHICLE WAS TOWED TO A TOYOTA DEALER AND DIAGNOSED, I WAS INFORMED THAT THERE WAS AN INTERNAL LEAK IN THE HYDRAULIC UNIT OF THE BRAKING SYSTEM, AND THAT THE ABS PUMP MODULE AND BRAKE MASTER CYLINDER NEEDED REPLACEMENT. THIS WAS A VERY SIMILAR ISSUE TO A RECALL OF OTHER 2010 TOYOTA PRIUS VEHICLES, BUT THE RECALL DOES NOT APPLY TO MY VIN NUMBER. TOYOTA CLAIMS THAT THE PROBLEM WAS "REMEDIED" BEFORE MY VEHICLE WAS PRODUCED EVEN THOUGH ONE OF MY TROUBLE CODES IS THE SAME AS THE TROUBLE CODE REFERRED TO IN THE RECALL.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT AN UNKNOWN SPEED, THE BRAKES SUDDENLY FAILED TO OPERATE WHEN THE BRAKE PEDAL WAS DEPRESSED. DURING THE INCIDENT, THE INSTRUMENT PANEL LIGHTS ILLUMINATED AND AN AUDIBLE SIGNAL WAS PRESENT INSIDE THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE BRAKE BOOSTER WAS FAULTY AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND THE CONTACT WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES, HYDRAULIC). THE FAILURE MILEAGE WAS 98,000.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT VARIOUS SPEEDS, THE BRAKE PEDAL WAS DEPRESSED BUT THE VEHICLE FAILED TO SLOW DOWN. THE CONTACT HAD TO DEPRESS THE BRAKE PEDAL WITH EXTREME FORCE IN ORDER FOR THE VEHICLE TO STOP. THE YELLOW AND RED BRAKE SYSTEM WARNING INDICATORS AND THE ABS WARNING INDICATOR ILLUMINATED. THE CONTACT ALSO STATED THAT THE BRAKE PEDAL FELT LIKE A SPONGE ONCE THE BRAKE PEDAL WAS FULLY DEPRESSED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE BRAKE BOOSTER ASSEMBLY AND THE BRAKE BOOSTER PUMP ASSEMBLY FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES). THE FAILURE MILEAGE WAS UNKNOWN.

THE TOYOTA PRIUS I HAVE HAS A RECALL, I BROUGHT THE CAR TO TOYOTA HAMER DEALER IN MISSION HILLS, THEY RELEASED THE CAR BACK TO ME AFTER THE I RECIEVED A BRAKES RECALL, I EXPERIENCED SCARY UNSAFE EXPERIENCE IN THIS CAR. THE CAR WAS PARK IN A UP SLOP DRIVEWAY, MY FAMILY WAS INSIDE, THE CAR TURNED ON, I HAD MY BRAKE PEDDLE PRESSED, AS I SHIFTED INTO REVERSE THECAR MOVED AND STOPPED IN A VIOLENT WAY TO A STOP, I TRIED GENTLY LETTING GO OF THE BRAKE PADDLE AND AGAIN THE CAR MOVED SWIFTLY WITH THE BRAKES ENGAGED TO A VIOLENT STOP. THIS IS VERY UNSAFE.

MY CAR AT 139,500 MILES DRIVING STRAIGHT ON A MAIN ROAD AT 45 MPH HAD THREE LIGHTS COME ON, RED 'BRAKE' LIGHT, YELLOW 'ABS' LIGHT AND THE YELLOW 'TCS' LIGHT. EARL STEWART TOYOTA DIAGNOSED PROBLEM AS BRAKE ACTUATOR NEEDS TO BE REPLACED AT A COST OF LABOR/PARTS OF 2,100$. I WAS ABLE TO FINANCIALLY AFFORD THE REPAIR SO I TOLD THEM TO PERFORM THE REPAIR. LESS THAN TWO DAYS LATER, DRIVING NORMALLY ON A MAIN ROAD, THE SAME THREE WARNINGS APPEARED, AND OF COURSE UPSET ME GREATLY. TOYOTA THIS TIME DIAGNOSED THE PROBLEM THIS TIME AS THE BRAKE BOOSTER NEEDS TO BE REPLACED. ANOTHER DEALER SAID THE BRAKE MASTER CYLINDER NEEDED TO BE REPLACED. I AM IN TALKS WITH THE DEALER TO FIGURE OUT HOW TO PROCEED.

THE ISSUES IS MY BRAKES. WHEN I AM SLOWING DOWN AT AN INTERSECTION, TYPICALLY WHEN THE ROAD IS WET, IF ANY OF MY WHEELS PASSES OVER A MANHOLE, OR PAVEMENT STRIPING THAT IS SLICKER THAN THE PAVEMENT, THE BRAKES WILL RELEASE. ON SEVERAL OCCASIONS, MY CAR HAS GONE THROUGH OR PARTIALLY THROUGH THE INTERSECTION. RECENTLY THIS CAUSED ME TO RUN A RED LIGHT. THIS HAS BEEN GOING ON SINCE I PURCHASED THE CAR USED . I TOOK IT TO THE DEALER (BURIEN AUTO, BURIEN, WA) ABOUT 18 MONTHS AGO WITH A NOTE EXPLAINING WHAT IS HAPPENING, AND THE MECHANIC SAID HE ROAD TESTED IT AND THERE WAS NO PROBLEM.

DRIVER MADE A SUDDEN STOP TO AVOID AN ACCIDENT ON 2/16/15, ENGAGING THE BRAKES. AFTERWARD THE BRAKES ALTERNATED BETWEEN BEING HARD TO PUSH AND BEING SOFT TO PUSH. DRIVER PARKED THE VEHICLE 5 MINUTES LATER. THE NEXT TIME THE CAR WAS TURNED ON(APPROXIMATELY 60M LATER), THE CAR BEGAN BEEPING AND SHOWING THREE ERROR LIGHTS - ABS, (!), AND THE TRACTION CONTROL SYMBOL. AFTER RUNNING DIAGNOSTICS, THE DRIVER WAS TOLD BY A MECHANIC THAT THE PROBLEM SOUNDED EXACTLY LIKE A PREVIOUSLY ISSUED RECALL (TCP-D0H); HOWEVER, TOYOTA HAS INDICATED THAT OUR MODEL IS OUTSIDE THE SCOPE OF THEIR RECALL. GIVEN THAT WE HAVE THE SAME MAKE/MODEL/YEAR CAR AS THE RECALL AND THE SAME ISSUE DESCRIBED, THE SITUATION IS HIGHLY SUSPECT. IN ADDITION TO INSURING MY OWN FAMILY'S SAFETY, I'M HOPING TO MAKE SURE THIS POTENTIALLY DANGEROUS BRAKE ISSUE ISN'T MORE WIDESPREAD THAN TOYOTA HAS ADMITTED.

WHEN BRAKING ON A BUMPY ROAD, OVER A POT HOLE OR ON SLIPPERY ROAD THE BRAKES SLIP AND THE CAR PROPELS FORWARD . THIS HAPPENS ON CITY STREETS WHILE IN MOTION.

DRIVING ON HIGHWAY THE ABS AND BRAKE WARNING LIGHTS CAME ON AND AN ALARM STARTED SOUNDING. I WAITED UNTIL LIGHT TRAFFIC APPLIED BRAKES PEDAL FELT LIKE I WAS PRESSING ON A BRICK, NO BRAKING OCCURRED I PRESSED HARDER, THE BRAKES BECAME SOFTER WENT TO THE FLOOR AND THE BRAKE PADS GRABBED HARD ON THE WHEELS. THERE IS NO CONTROLLED BRAKING ON THE CAR. DEALERSHIP SAYS THE BRAKE BOOSTER PUMP FAILED, THIS IS THE SAME YEAR MODEL THAT HAD BRAKING PROBLEMS RELATED TO NITROGEN IN THE BREAK LINES CAUSED BY A FAILED BRAKE BOOSTER PUMP. THE VIN IS ALSO VERY CLOSE TO AFFECTED VEHICLES. FORTUNATELY WHEN THIS OCCURRED I WAS IN A POSITION TO NAVIGATE TO WHERE I COULD TEST THE BRAKES IN A FAIRLY CONTROLLED ENVIRONMENT. HAD IT HAPPENED IN HEAVY TRAFFIC IT WOULD HAVE ALMOST CERTAINLY RESULTED IN A SERIOUS ACCIDENT.

AS I WAS DRIVING, I NOTICED THAT WHEN I PRESSED ON THE BRAKES, THE CAR WOULD JERK FORWARD BEFORE COMING TO A STOP. ONCE STOPPED (BUT STILL TURNED ON), THE CAR MADE A BUZZING NOISE I HAD NEVER HEARD BEFORE. NO WARNING LIGHTS CAME ON, AND THE BRAKES DID NOT SQUEAK. AN HOUR LATER, MY HUSBAND DROVE THE CAR HOME FOR ME (I RODE WITH A FRIEND), AND HE REPORTED THAT WARNING LIGHTS CAME ON AND THE BRAKES DID NOT WORK PROPERLY. IN ORDER FOR THE BRAKES TO WORK, HE HAD TO PRESS VERY HARD ON THEM AND ALSO ALLOW MUCH MORE DISTANCE FOR THE CAR TO STOP. HE COULD HAVE EASILY CRASHED INTO THE BACK OF ANOTHER VEHICLE. HE TOOK THE CAR TO THE TOYOTA DEALERSHIP AND WAS INFORMED THE BRAKE BOOSTER ASSEMBLY WOULD HAVE TO BE REPLACED. THIS IS THE SAME COMPLAINT AS A 2010 PRIUS RECALL, BUT MY VIN NUMBER WAS NOT INCLUDED IN THE RECALL, SO I DID NOT RECEIVE A NOTICE IN THE AIL. ALSO, WE HAD TO PAY $3008 TO HAVE THE BRAKE BOOSTER ASSEMBLY REPLACED. THE CONSUMER REFERENCED RECALL # 13V235000. UPDATED 02/11/16. *JB

LOSS OF BRAKE PRESSURE, WITH INSUFFICIENT BREAKING TO HOLD AT A STOP WHILE IN DRIVE. WARNING LIGHTS FOR BRAKE SYSTEM, ABS, ELECTRONIC BRAKE SYSTEM (YELLOW EXCLAMATION POINT IN A CIRCLE), AND TRACTION CONTROL. DIAGNOSED BY BROWN TOYOTA IN CHARLOTTESVILLE VA AS FAULTY BRAKE BOOSTER, ACCUMULATOR, AND MASTER CYLINDER. BROWN TOYOTA SAID IT WAS A RECURRING PROBLEM THEY HAVE ENCOUNTERED AND THEY HAVE BEEN IN CONTACT WITH TOYOTA HEADQUARTERS ABOUT IT. ESTIMATE WAS $5800. TOYOTA CUSTOMER SERVICE WAS CONTACTED. WAS TOLD IT IS NOT ONE OF THE 2010 CARS COVERED BY THE RECALL DESPITE BEING THE SAME FAILURE AND NO COMPENSATION WAS OFFERED.

VEHICLES BRAKES ARE SPONGY AND UNPREDICTABLE. THE DEALER RECOMMENDED TO DO A BRAKE FLUID EXCHANGE AND NOW THE PROBLEM HAS GONE AWAY. THIS ISSUE SEEMS VERY SIMILAR TO NHTSA CAMPAIGN ID NUMBER: 13V235000, WHERE NITROGEN ENTERS THE BRAKE FLUID AND MAKES THE BRAKES LESS RESPONSIVE. HOWEVER, THE DEALER SAID THIS VEHICLE IS NOT COVERED BY THAT RECALL AND I WAS CHARGED $150 FOR THE REPAIR.....UPDATED 12/02/15 *BF THE CONSUMER STATED THE BRAKES FELT SPONGY AND WERE UNPREDICTABLE AT LOW SPEEDS OF LESS THAN 20 MPH. UPDATED 12/28/15. *JB

WHEN APPLYING THE BREAKS BEFORE AND OVER RAILROAD TRACKS, THE BREAKING WILL DISENGAGE AND THEN REENGAGE. IT WILL ALSO HAPPEN WITH POT HOLES. YOU GET THE FEELING THE CAR WON'T STOP. THIS HAS BEEN HAPPING FOR YEAR AND THE SERVICE DEPARTMENT GIVES DIFFERENT ANSWERS TO THE CAUSE.

WHILE DECELERATING DUE TO APPLICATION OF THE BRAKE PEDAL IF THE VEHICLE ENCOUNTERS A POTHOLE OR OTHER DEEP ROAD IMPERFECTION THE BRAKING CUTS OUT AND THE VEHICLE RESUMES COASTING IMMEDIATELY EVEN THOUGH THE BRAKE PEDAL IS DEPRESSED. HARDER APPLICATION OF THE BRAKE PEDAL IS NECESSARY TO RESUME VEHICLE BRAKING. SUBSEQUENT BRAKING POWER IS MUCH REDUCED COMPARED TO NORMAL BRAKING AND SIGNIFICANTLY HARDER BRAKE PEDAL PRESSURE IS NECESSARY. NORMAL BRAKING MAY BE REESTABLISHED BY LIFTING THE FOOD OFF THE BRAKE PEDAL COMPLETELY AND RE-DEPRESSING THE BRAKE PEDAL. THE SEVERITY OF THE SUDDEN LOSS OF BRAKING (COMPLETE LOSS OF BRAKING) IS SHOCKING, ALARMING, AND PANIC ENDUCING AND RESULTS IN WHIPLASH TO THE VEHICLE OCCUPANTS AS THE PASSENGERS, BEING UNCONSCIOUSLY BRACED FOR DECELERATION, ARE SUDDENLY JOLTED BACK INTO THEIR SEATS. WHEN ANOTHER VEHICLE IS LOCATED IN FRONT OF THE VEHICLE THE SUDDEN LOSS OF BRAKING AND SUBSEQUENT WEAK BRAKING POWER DESPITE STRONG BRAKE PEDAL DEPRESSION IS HIGHLY ALARMING. THE MOST REPRODUCIBLE SITUATION IN WHICH THIS HAPPENS IS ON DRY PAVEMENT WHILE EXITING A HIGHWAY AND DECELERATING ON A STRAIGHT OR SLIGHTLY CURVED EXIT RAMP WITH ONE OR MORE POTHOLES. THE PHENOMENON OCCURS IN OTHER CIRCUMSTANCES AS WELL WHERE A POTHOLE IS ENCOUNTERED WHILE THE VEHICLE IS UNDER BRAKING.

I HAVE HAD THIS PROBLEM EVER SINCE I BOUGHT THIS CAR USED FROM A TOYOTA DEALERSHIP. IF I DRIVE OVER AN UNEVEN SURFACE, POTHOLE, ETC., MY CAR WILL SKIP AND THEN LURCH FORWARD. IT IS WORST ON WET ROADS. I HAVE TROUBLE STOPPING IT. ON SNOW I HAVE LITTLE TO NO TRACTION. I GOT A NEW SET OF TIRES AND I WASTED MY MONEY. NO DIFFERENCE. I DON'T FEEL SAFE DRIVING THIS VEHICLE. I HAVE BEEN DRIVING FOR YEARS, HAD MANY DIFFERENT VEHICLES, DRIVE AS PART OF MY JOB, AND HAVE NEVER EXPERIENCED ANYTHING LIKE IT. CONTACTING TOYOTA ABOUT IT WAS A WASTE OF TIME. I HAVE SPOKEN TO OTHER PRIUS 2010 OWNERS AND EVERY ONE SAYS THE SAME THING ABOUT HOW IT HANDLES WHEN GOING OVER BUMPS. THE SKIP AND LURCH COULD EASILY RESULT IN A REAR END COLLISION. I THINK THIS IS SOMETHING TOYOTA JUST DOESN'T WANT TO ADMIT TO AS BEING A PROBLEM.

CAR SEEMS TO LURCH FORWARD BEFORE STOPPING WHEN BRAKING ON A ROUGH SURFACE. THIS IS AN ONGOING PROBLEM. DESPITE NHTSA NOTICE THAT THERE IS A SOFTWARE FIX AVAILABLE FOR SOME 2010 PRIUSES, TOYOTA MAINTAINS MY CAR IS NOT INCLUDED IN THE BATCH THAT WAS TO RECEIVE THEM. UPDATE 9/15/15*CW UPDATED 12/06/2017*CN

WE HAVE EXPERIENCED INCONSISTENT BREAK FEEL AFTER ABS ACTUATION DURING SLOW AND STEADY APPLICATION OF THE BRAKES ON ROUGH OR SLICK ROAD SURFACES. WE NOTICED ALSO THAT THERE WAS A RECALL ON THIS ISSUE IN 2010 BUT OUR PARTICULAR CAR (BY VIN NUMBER) DID NOT QUALIFY. WE THINK THAT THE RECALL SHOULD HAVE INCLUDED A BROADER SAMPLE OF SAME YEAR AND MODEL. WE HAVE BROUGHT THE PROBLEM TO THE ATTENTION OF THE DEALERSHIP SEVERAL TIMES BUT THEY HAVE DISMISSED IT AS NORMAL OPERATION OF BRAKES. WE FEEL VERY UNSAFE IN THE VEHICLE.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 10 MPH, THE BRAKE PEDAL WAS DEPRESSED AND FAILED TO RESPOND. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 56,000.

I READ THE COMPLAINTS & FOUND ONE LISTED RECENTLY DATED 5/22/15 THAT DESCRIBES THE EXACT PROBLEM I HAVE. MY PRIUS IS A 2010 PURCHASED IN 7/09 & SHORTLY THEREAFTER, I NOTICED THE BRAKING ISSUE. THE FOLLOWING INFO IN QUOTES IS COPIED FROM THE OTHER COMPLAINT WHICH IS THE SAME ISSUE I HAVE - (OTHER COMPLAINT STATED) "WHEN YOU ARE AT LOWER SPEEDS AND HIT A POTHOLE OR BIG BUMP WHILE BREAKING, THERE'S A SUDDEN 'JOLT' AND IT FEELS AS IF THE BREAKS HAVE BEEN COMPLETELY RELEASED MOMENTARILY. IT ALMOST FEELS AS IF THE CAR LURCHES FORWARD. I FEEL IT HEIGHTENS THE CHANCE OF A CRASH DUE TO INCREASED DECELERATION TIME." IT SOMETIMES FEELS LIKE YOU ARE SLIDING ON ICE & HAVE NO CONTROL OVER THE CAR. (AND IT IS SCARY WHEN IT HAPPENS!) I HAD TOYOTA CHECK MY VEHICLE A FEW TIMES, BUT THEY WERE NOT ABLE TO DUPLICATE THE PROBLEM, SO NOTHING WAS FIXED. I THOUGHT IT WAS JUST MY CAR THIS WAS HAPPENING TO. NOW I FIND THAT I AM NOT ALONE IN THIS. THE COMPLAINT I REFERENCED STATED THAT THERE WAS AND A "PREVIOUS INVESTIGATION & PARTIAL RECALL BUT IT DIDN'T AFFECT ALL OF THE 2010 PRODUCTION VEHICLES, JUST A PORTION." I NEVER HEARD ABOUT ANY RECALL OR INVESTIGATION ON THIS. I AGREE WITH THE OTHER COMPLAINT THAT "THIS NEEDS TO BE RE-INVESTIGATED AS MY CAR AND COUNTLESS OTHER CARS (BOTH INVOLVED AND NOT INVOLVED IN THE LAST RECALL) ARE (STILL) MALFUNCTIONING WHEN IT COMES TO THE BREAKING SYSTEM AT SLOWER SPEEDS WHEN ON ROUGH ROADS / ENCOUNTERING POTHOLES / BUMPS." MY CAR STILL HAS THIS PROBLEM EVEN AS IT IS NOW 5 YEARS OLD. WHAT NEEDS TO BE DONE TO CORRECT THIS ISSUE?

EXPERIENCE INCONSISTENT BRAKE FEEL AFTER ABS ACTUATION DURING SLOW AND STEADY APPLICATION OF THE BRAKES ON ROUGH OR SLICK ROAD SURFACES. STOPPING DISTANCES INCREASE.

I HAVE OWNED TWO PRIUS AND BOTH OF THEM HAVE HAD THE SAME BREAKING ISSUE. WHEN YOU ARE AT LOWER SPEEDS AND HIT A POTHOLE OR BIG BUMP WHILE BREAKING, THERE'S A SUDDEN 'JOLT' AND IT FEELS AS IF THE BREAKS HAVE BEEN COMPLETELY RELEASED MOMENTARILY. IT ALMOST FEELS AS THE CAR LURCHES FORWARD. I TRY TO AVOID POTHOLES, ETC ANYWAYS, BUT I AM EXTRA VIGILANT BECAUSE OF THIS ISSUE AS I FEEL IT HEIGHTENS THE CHANCE OF A CRASH DUE TO INCREASED DECELERATION TIME. LAST NIGHT, I WAS COMING UP TO AN INTERSECTION THAT HAD A YIELD SIGN. THE CAR IN-FRONT OF ME STOPPED. I HIT MY BREAKS, BUT WHILE BREAKING, I HIT A POTHOLE (IT AS DARK SO I COULDN'T SEE IT) MY BREAKS SUDDENLY BEHAVED AS DESCRIBED ABOVE - THEY LET GO FOR A MOMENT AND THE CAR SOMEWHAT JOLTED FORWARD. I WAS UNABLE TO STOP IN-TIME AND REAR-ENDED THE DRIVER AHEAD OF ME. I WAS ALWAYS AFRAID THAT BECAUSE OF THIS BREAKING ISSUE THAT THIS WOULD HAPPEN - AND NOW IT HAS. I KNOW THERE WAS A PREVIOUS INVESTIGATION AND A PARTIAL RECALL BUT IT DIDN'T AFFECT ALL OF THE 2010 PRODUCTION VEHICLES, JUST A PORTION. I FEEL THIS NEEDS TO BE RE-INVESTIGATED AS MY CAR AND COUNTLESS OTHER CARS (BOTH INVOLVED AND NOT INVOLVED IN THE LAST RECALL) ARE (STILL) MALFUNCTIONING WHEN IT COMES TO THE BREAKING SYSTEM AT SLOWER SPEEDS WHEN ON ROUGH ROADS / ENCOUNTERING POTHOLES / BUMPS.

HAVE OWNED THE CAR SINCE NEW IN 2010. BRAKES EXHIBIT THE SAME ISSUE MENTIONED IN OTHER COMPLAINTS I.E. WHEN GOING OVER BUMPY ROADS, BRAKES "RELEASE" AND RE-ENGAGE CAUSING THE CAR TO NOT STOP QUICKLY. HAD SOFTWARE RECALL DONE BUT DID NOT SIGNIFICANTLY AFFECT. HAVE JUST BEEN LIVING WITH IT BUT AFTER SEEING ALL OTHER COMPLAINTS, THOUGHT I WOULD WEIGH IN WITH THE SAME PROBLEM AS IT APPEARS TO BE A COMMON ISSUE WITH A DESIGN FLAW OF SOME SORT THAT NEEDS TO BE ADDRESSED FOR SAFETY REASONS.

CAR CAME OUT OF THE CAR WASH AND AS I GOT READY TO PULL OUT THE BRAKE LIGHT CAME ON AND THERE WAS A RAPID BEEP. PUSHED ON THE BRAKES AND FELT NO RESISTANCE LIKE BRAKES DID NOT EXIST. HAD THE CAR TOWED TO THE DEALER (RIGHT TOYOTA ON FRANK LLOYD - SCOTTSDALE AZ) - DEALER RAN A SOFTWARE TO FIX IT (PART OF A RECALL) BUT THAT DID NOT FI X THE ISSUE. DEALER ASKED ME TO HAVE HYDRO BOOSTER PUMP AND THE ASSEMBLY REPLACED - THEY CHARGED ME $4200 FOR PARTS AND LABOR. I WAS FORCED TO PAY AS THEY SAID THEY TRIED TO FIX IT THROUGHT HE SOFTWARE BUT IT DID NOT. I FEEL THAT TOYOTA IS REPSONSIBLE FOR THE SYSTEM FAILURE - THE BRAKES ARE CRITICAL - THEY SUDDENLY STOPED WORKING. IT COULD HAVE BEEN FATAL IF I WAS ON THE ROAD WHEN IT HAPPENED. THE FAILURE SHOULD BE GRADUAL AND THERE SHOULD BE A CERTAIN WARNING IF THE PUMP WAS MALFUNCTIONING. I NEED YOUR HELP IN RESOLVING THIS. TOYOTA SHOULD BE RESPONSIBELF RO PAYING THE INVOICE.

I HAVE NOTICE A DEFINITE RELEASE IN BRAKING ACTION WHEN MY 2010 PRIUS GOES OVER A PATCH OF BUMPY ROAD, WITHIN 1 MINUTE OF LEAVING MY HOME AND GOING DOWN THE BLOCK. I EXPERIENCE THIS "RELEASE" OF BRAKING AS A SUDDEN BRIEF ACCELERATION THAT OCCURS WHILE THERE IS PRESSURE ON THE BRAKE PEDAL TO SLOW DOWN WHILE GOING OVER THE BUMPY PATCH OF ROAD ( A 20 FOOT STRETCH OF ROAD WITH NUMEROUS SHALLOW POTHOLES). I BOUGH THIS CAR USED IN SEPTEMBER 2013. (IT HAD 80,000 MILES ON IT AND A HISTORY OF TRAVEL OVER GRAVEL ROADS). ON MARCH 20, 2014, THE LOCAL DEALER DID THE E0E RECALL REPAIR ON THE MOTOR GENERATOR ECU AND THE POWER MANAGEMENT ECU, TO CORRECT ISSUES RELATED TO HARD ACCELERATION. AT THE SAME TIME, THE DEALER DID THE OLDER TOYOTA RECALL REPAIR ON THE BRAKE PRESSURE ACCUMULATOR ISSUE. I HAVE NOT NOTICED THIS BRAKING RELEASE ISSUE LATER IN THE DAY. IT SEEMS TO BE MOST NOTICEABLE FIRST THING IN THE MORNING, IN THE FIRST MINUTE OR TWO OF DRIVING.

THE TOYOTA DEALER DIAGNOSED A BRAKE MASTER CYLINDER AND BOOSTER FAILURE ON OUR 2010 PRIUS AT 27892 MILES. TOYOTA DECLINED TO EXTEND THE BRAKE RECALL THAT COVERED 2010 CARS WITH A PRODUCTION DATE BEFORE NOVEMBER 2009. OUR CAR HAS A MARCH 2010 PRODUCTION DATE. CLEARLY TOYOTA WAS ASSEMBLING CARS WITH FAULTY BRAKE MASTER CYLINDERS AND BOOSTERS AND THEY SHOULD EXTEND THE RECALL TO COVER THOSE CARS. THE COST OF THE REPAIR WAS $2760. *TR

AS I WAS COMING TO A COMPLETE STOP AT AN INTERSECTION, THE CAR JOLTED AS IF I WAS HIT FROM BEHIND AND THE BRAKES LOST PRESSURE RESULTING IN ME HAVING TO PRESS THE PEDAL ALL THE WAY DOWN TO THE FLOOR. THE BRAKES WOULD NOT RESPOND AND I HAD TO PUT THE CAR IN PARK TO GET IT TO STOP. THE SAME THING HAPPENED AFTER I FIRST GOT THE VEHICLE IN 2010. IN SEPT. 2010, THE BRAKES DID NOT RESPOND, CAUSING ME TO SLIDE INTO THE ROW AND RESULTING IN AN ACCIDENT. THE CAR WILL ALSO JOLT WHEN THE BRAKES ARE PRESSED WHILE DRIVING OVER A POTHOLE OR BUMP. I TOOK THE VEHICLE IN TO HAVE THIS CHECK ON 4/2/15 AT TOYOTA OF LEWISVILLE, IN LEWISVILLE, TX. THEY CLAIM THAT EVERYTHING CHECKS OUT FINE ON THE BRAKES AND THEY CAN NOT GET IT TO REPLICATE THE JOLT OR PRESSURE FAILURE. PER TOYOTA OF LEWISVILLE, THE CAR DID HAVE A RECALL FOR THE BRAKES, WHICH WAS REPAIRED AT TOYOTA OF IRVING, BUT THE BRAKES ARE STILL EXHIBITING PROBLEMS. *TR

THIS BRAKE PROBLEMS HAS OCCURRED MANY TIMES. DURING APPLICATION OF THE BRAKES AT LOW SPEEDS ON ROUGH ROAD SURFACES THE CAR SUDDENLY LOSES BRAKING POWER FOR A BRIEF TIME THEN STARTS TO WORK AGAIN IF THE BRAKE PEDAL REMAINS DEPRESSED. THIS HAS ALMOST CAUSED ACCIDENTS A NUMBER OF TIMES AND IS QUITE FRIGHTENING. THE CAR WAS BROUGHT IN FOR THE RECALL AND SAFERCAR.GOV STATES THAT THERE ARE NO OPEN RECALLS. WHEN WE BRING THIS TO THE ATTENTION OF THE TOYOTA DEALER WE ARE TOLD THIS PROBLEM IS "NORMAL" AND THERE IS NOTHING MORE THEY CAN DO. (HOWEVER, I UNDERSTAND THAT THEY FIXED IT IN THE NEXT MODEL YEAR.) IN MY OPINION THIS IS AN UNSAFE CONDITION AND IT HAS BEEN COMPLAINED ABOUT ONLINE BY OTHER PRIUS OWNERS. I ASK THE NHTSA TO REQUIRE TOYOTA TO FIX THIS IN THE NAME OF SAFETY. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT APPROXIMATELY 5 MPH, THE BRAKING ABILITY SEIZED AND THE ABS WARNING LIGHT ILLUMINATED. THE CONTACT CAME TO A COMPLETE STOP AND THE VEHICLE HAD TO BE RESTARTED. THE VEHICLE WAS DRIVEN TO THE DEALER WHO STATED THAT THE HYDRAULIC SYSTEM FAILED. THE HYDRAULIC MASTER CYLINDER HAD TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 27,000.

IT WAS RAINING AND I WAS EXISTING THE I5 RAM, WHEN I BUMPED THE BRAKE, THE VEHICLE SPEEDED UP MORE, I CONTINUE TO PUMP THE BRAKE, THEN THE VEHICLE STARTED DRIFTING, THEN I TRIED CORRECTING, BUT IT DIDN'T WORK, THE VEHICLE KEPT ON DRIVING, FOR ABOUT 15 SECONDS COME TO STOP BY THE WALL OF THE I5, IT THEN BOUNCED VEHICLE BACKWARDS AND FINALLY THE VEHICLE COME TO STOP AFTER THE SHIFT BROKE, CAUSEING A TOTALLY CRASH, MEANING, NO MATTER HOW HARED I STEP ON THE BRAKE, IT DIDN'T STOP, IT FELT LIKE THERE WAS NO BRAKE SYSTEM. I ONLY BOUGHT THE CAR FOR 6 DAYS EARLIER, AND IT WAS MY THIRD TIME DRIVING IT. I HAVE BEEN A DRIVE FOR 7 YEARS AND I HAVE NEVER HAD ANY INCIDENT. *TR

WHILE DRIVING AROUND 70MPH I HAD TO HIT THE BRAKES HARD BUT SHORT. ABOUT 5 SECONDS LATER A BUNCH OF WARNING LIGHTS CAME ON AND THE VEHICLE BECAME VERY DIFFICULT TO STOP. PRETTY MUCH HAD TO STAND ON THE BRAKES TO SLOW DOWN AND THEN THE BRAKES WOULD LOCK UP SO I WOULD GET OFF THE BRAKES AND START THE SLOWING/STOPPING PROCESS OVER AGAIN. THIS IS THE SAME FAILURE MODE (ABS ACCUMULATOR NITROGEN GAS LEAKED INTO BRAKE HYDRAULIC FLUID WHEN ACCUMULATOR CRACKED) AS OTHER CARS (PRIUS AND LEXUS HYBRIDS) THAT TOYOTA DID RECALL BUT MY CAR IS OUTSIDE OF THE CURRENT RECALL SCOPE. IF THIS WAS NOT IN SOUTHERN CALIFORNIA'S DRY ROAD A MAJOR INCIDENT COULD HAVE TAKEN PLACE, ESPECIALLY WITH THE GRABBING/ LOCKING UP OF THE BRAKES. *TR

BRAKE PEDAL LOSES PRESSURE WHILE BRAKING OVER BUMPS IN ROAD. PRESSURE RETURNS AFTER BUMPS ARE PASSED. RECALL ISSUED AND SOFTWARE FIX PROVIDED BY DEALER IN MARCH 2010. SOFTWARE FIX DIDN'T HELP. SIMILAR CONDITION HAS PERSISTED SINCE THEN. BOUGHT VEHICLE NEW. MILEAGE AND DATE WHEN FIRST NOTICED CONDITION ARE ESTIMATES. AFTER SOFTWARE FIX, NOTICED CONDITION AGAIN IMMEDIATELY. *TR

WHILE APPLYING THE BRAKES TO STOP AT AN INTERSECTION ONE OF THE FRONT TIRES WAS OVER A MANHOLE COVER AND THE CAR SKIDDED OVER IT LIKE I WAS BRAKING ON A PATCH OF ICE. AS SOON AS I WAS PAST THE COVER THE BRAKES ENGAGED AND STOPPED THE CAR. I NOTICED THIS OCCURRING EVERY TIME I WOULD BRAKE ON AN UNEVEN SURFACE WHERE THERE WAS SPACE BETWEEN ONE OF THE FRONT TIRES AND PAVEMENT. I HAD BOUGHT THE SAME MAKE, MODEL AND YEAR VEHICLE FOR MY SON 11 MONTHS LATER AND NOTICED THE SAME PROBLEM WHILE TEST DRIVING IT. WHEN I QUESTIONED THE SALESMAN ABOUT IT I WAS TOLD THAT IT WAS THE WAY THE ABS WORKS AND THAT IT WAS NORMAL. ON 11/20/2014 WHILE CHECKING THE AIRBAG RECALL LIST I NOTICED A RECALL FOR THE SAME PROBLEM THAT I WAS HAVING, RECALL ANNOUNCED 2/9/2010, NHTSA REF # 10V03900 SO I CALLED TOYOTA CUSTOMER SERVICE 1-800-331-4331 AND WAS TOLD THAT NEITHER CARS' VIN# SHOWED IN THE RECALL SO IT COULD NOT BE HAPPENING AND I WOULD NOT BE COVERED UNDER THE RECALL. THEY REFERRED ME TO A TOYOTA DEALER WHO TOLD ME THAT THE FIX WHICH WAS (REPROGRAMMING OF ABS CONTROL UNIT MODULE) WOULD NOT COVERED IN THE EXTENDED WARRANTIES OF EITHER CARS. I SHOULD NOT BE FINANCIALLY RESPONSIBLE FOR THE DIAGNOSTICS AND REPAIRS OF A KNOWN SAFETY PROBLEM WHICH HAD A RECALL. I UNDERSTAND THAT IT IS NOT THE DEALERS' FAULT AND THEY SHOULDN'T BE HELD FINANCIALLY RESPONSIBLE EITHER. *TR

WHEN BRAKING WHILE APPROACHING STOP SIGN HAVING SLOWED TO ~10 MPH, I ENCOUNTERED A BUMPY SECTION OF ROAD. THE BRAKES FEEL LIKE THEY RELEASED FOR ~1 SEC CAUSING THE VEHICLE TO LURCH FORWARD BEFORE THEY (BRAKES) KICKED IN AGAIN. THIS HAS HAPPENED 5-10 TIMES SINCE I BOUGHT THE CAR USED FROM THE TOYOTA DEALER IN 4/2013. MY COMPLAINT MIRRORS THOSE THAT RESULTED IN THE RECALL BELOW BUT MY TOYOTA DEALER SAYS, BASED ON MY VIN THAT MY CAR WAS NOT AFFECTED. REPORT RECEIPT DATE: FEB 09, 2010 NHTSA CAMPAIGN NUMBER: 10V039000 COMPONENT(S): SERVICE BRAKES, AIR ALL PRODUCTS ASSOCIATED WITH THIS RECALL VEHICLE MAKEMODELMODEL YEAR(S) LEXUSHS2010 TOYOTAPRIUS2010 DETAILS 17 ASSOCIATED DOCUMENTS MANUFACTURER: TOYOTA MOTOR NORTH AMERICA, INC. SUMMARY: TOYOTA IS RECALLING CERTAIN MODEL YEAR 2010 TOYOTA PRIUS AND LEXUS HS250H PASSENGER VEHICLES. CUSTOMERS HAVE EXPERIENCED INCONSISTENT BRAKE FEEL AFTER ABS ACTUATION DURING SLOW AND STEADY APPLICATION OF THE BRAKES ON ROUGH OR SLICK ROAD SURFACES. STOPPING DISTANCES MAY BE INCREASED COMPARED WITH A CUSTOMER'S EXPECTATION FOR A GIVEN PEDAL FORCE. CONSEQUENCE: VEHICLE STOPPING DISTANCES MAY INCREASE RELATIVE TO A CUSTOMER'S EXPECTATION INCREASING THE RISK OF A CRASH. REMEDY: DEALERS WILL REWRITE THE PROGRAMMING OF THE ABS CONTROL UNIT FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 3, 2010, AND IS EXPECTED TO BE COMPLETED IN LATE MARCH 2010. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331 AND LEXUS AT 1-800-255-3987. *TR

THIS IS RELATED TO REPORT RECEIPT DATE: FEB 09, 2010 (I BOUGHT THE CAR USED IN MAY, 2013). NHTSA CAMPAIGN NUMBER: 10V039000 COMPONENT(S): SERVICE BRAKES, AIR - THIS HAPPENS ALL THE TIME WHEN THE CONDITIONS ARE RIGHT. I COMPLAINED TO TOYOTA AT THE TIME THAT THIS CAR SHOULD HAVE BEEN IN THE RECALL LIST - IT DOES EXACTLY AS DESCRIBED IN THIS CAMPAIGN DESCRIPTION...THE BRAKES RELEASE WHEN BRAKING OVER BUMPS OR SLIPPERY SURFACES. THE FIRST TIME I TOOK IT IN, THEY SAID THEY COULD FIND NOTHING WRONG, AND THEY WERE 'WORKING AS DESIGNED'. I CALLED TOYOTA TODAY AFTER READING MORE ABOUT THIS RECALL, AND THEY TOLD ME I WOULD HAVE TO TAKE TO SERVICE AND GIVE THEM A RIDE TO SHOW THEM HOW IT HAPPENS. I DON'T UNDERSTAND WHY THIS CAR WASN'T INCLUDED IN THE RECALL. ANY SUGGESTIONS OR ASSISTANCE? ARE YOU STILL GETTING COMPLAINTS ABOUT THIS? *TR

WHEN BRAKING ON ROUGH ROADS THE BRAKES WILL RELEASE, CAUSING THE CAR TO LUNGE FORWARD. VERY SCARY AND DANGEROUS. I TOOK MY CAR BACK TO TOYOTA DEALER TO HAVE THIS CHECKED OUT. THEY HAD NEVER HEARD OF THIS PROBLEM (EVEN THOUGH THERE IS A RECALL FOR IT). THEY CHECKED IT OUT AND TEST DROVE IT, BRAKING OVER ROUGH ROAD. THEY SAID IT WAS BRAKING FINE. IT IS STILL RELEASING WHEN BRAKING ON ROUGH PATCHES FOR ME. I AM ALWAYS MINDFUL TO LEAVE PLENTY OF ROOM BETWEEN ME AND THE CAR AHEAD OF ME IN CASE I HIT A ROUGH PATCH. I PLAN ON TAKING MY CAR BACK TO TOYOTA WITH A PRINTOUT FROM THIS SITE SHOWING IT HAS BEEN RECALLED FOR THIS VERY PROBLEM AND THAT OTHERS ARE ALSO EXPERIENCING THE SAME THING.

THIS IS A CHRONIC PROBLEM WITH THE CAR: WHEN IT HITS ROUGH TERRAIN, THE BRAKES DO NOT REACT PROPERLY. THERE IS A HESITATION BETWEEN THE TIME THE BRAKE PEDAL IS HIT AND THE TIME THE CAR SLOWS. (THERE WAS AN EARLIER REPAIR/RECALL FOR THIS ISSUE, AND THE INITIAL PROBLEM -- ALSO BRAKE-RELATED -- WAS HELPED; BUT THIS HESITATION PROBLEM -- ONLY ON GRAVEL OR ROUGH TERRAIN -- RESULTED.) IT WILL CAUSE AN ACCIDENT EVENTUALLY. *TR

I CONTINUE HAVING THIS ISSUE WHEN BRAKING OVER A BUMP OR BRAKING WHILE TURNING. THE CAR SPEEDS UP INSTEAD OF SLOWING DOWN WHEN PRESSING THE BRAKES. THIS IS VERY DANGEROUS ISSUE AND AN CAUSE AN ACCIDENT. I TALKED TO TOYOTA WHO ADVICE ME TO TAKE IT TO THE DEALER. DEALER FINDS NO TROUBLE. I HAVE REPORTED THIS MANY TIMES TO MY DEALER AND TOYOTA WITH NOTHING REALLY DONE. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING DOWN A HILL AT APPROXIMATELY 20 MPH, THE BRAKE PEDAL WAS DEPRESSED AND THE BRAKES FAILED TO RESPOND WITHOUT WARNING. THE VEHICLE WAS TOWED TO THE DEALER, WHO DIAGNOSED THAT THE BRAKE BOOSTER PUMP LEAKED NITROGEN INTO THE MASTER CYLINDER BRAKE BOOSTER ASSEMBLY THAT CAUSED THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN: 13V235000 (SERVICE BRAKES). THE APPROXIMATE FAILURE MILEAGE WAS 148,000.

I CONTINUE TO HAVE A PROBLEM WITH BRAKING WHEN GOING OVER A BUMPY SURFACE. THIS HAS HAPPENED NUMEROUS TIMES. MOST RECENTLY, WHILE DRIVING OVER A BUMP IN THE ROAD, I APPLIED THE BRAKES AND THE CAR LUNGED FORWARD. LUCKILY, THERE WAS ENOUGH DISTANCE BETWEEN MY CAR AND THE CAR IN FRONT OF ME (WHICH HAD ALSO APPLIED THE BRAKES). I AM AFRAID THIS WILL CAUSE A SERIOUS ACCIDENT SOMEDAY. THIS HAS ALSO HAPPENED AT STOP SIGNS. I HAVE COMPLAINED TO THE DEALERSHIP A FEW TIMES AND THEY ACT AS IF THEY DON'T KNOW WHAT I AM TALKING ABOUT, WHICH IS LUDICROUS. I EVEN MENTIONED THE ECU RECALL/FIX REGARDING THE BRAKING SYSTEM AND TOLD THEM THAT MY VEHICLE HAD THE FIX APPLIED AND THEY TOLD ME THAT THE FIX WAS NOT TO ADDRESS THE PROBLEM I AM DESCRIBING. THEY INSIST THAT NO ONE ELSE HAS COMPLAINED ABOUT IT. I TOLD THEM THAT I ASSUME THAT THEY HAVE BEEN DIRECTED TO TELL CUSTOMERS THAT THEY KNOW NOTHING ABOUT IT. I SEE SO MANY COMPLAINTS REGARDING THIS ISSUE AND I DON'T UNDERSTAND WHY NOTHING IS BEING DONE ABOUT IT. *TR

I PURCHASED THIS CAR IN 2010 AFTER THE 2010 BRAKE MALFUNCTION RECALL. I WAS TOLD THE RECALL SOFTWARE UPDATE HAD BEEN PERFORMED TO MY CAR. DESPITE THAT RECALL, MY CAR CONTINUES TO HAVE THE FOLLOWING PROBLEM ON A CONSISTENT BASIS. WHENEVER BRAKING AT SLOW SPEEDS, IF I GO OVER A BUMP OR POTHOLE WHILE BRAKING, THE BRAKES DISENGAGE, THE CAR LURCHES FORWARD, AND I HAVE TO SLAM ON THE BRAKES TO GET THE CAR TO SLOW DOWN/STOP. MY UNDERSTANDING IS THAT THIS PROBLEM WAS SUPPOSED TO HAVE BEEN FIXED BY THE PRIOR RECALL. *TR

BRAKING POWER IS NOT CONSISTENT. CAR IS HARD TO STOP. NEED TO PUSH THE PEDAL REALLY HARD TO STOP AT SPEED. THIS STARTED TO GET WORST AFTER THE RECALL. *TR

MASTER BRAKE CYLINDER AND BOOSTER, $4700 REPAIR. *TR

EVEN AFTER HAVING MY VEHICLE REPAIRED UNDER THE RECALL FOR THE ABS BRAKING ISSUE IN 2010, I CONTINUE TO HAVE BRAKING PROBLEMS WHEN BRAKING ON UNEVEN ROADS. 9/12/14 WAS MY MOST RECENT INCIDENT WHEN I CAME TO A STOP ON A DIRT ROAD AT AN INTERSECTION AND MY VEHICLE LUNGED FORWARD WHEN I WENT OVER A HOLE IN THE ROAD WHILE BRAKING. I WAS NOT GOING FAST, MAYBE 15 MPH, AND THERE WERE NO VEHICLES IN FRONT OF ME, BUT IT COULD HAVE RESULTED IN A CRASH IF THERE HAD BEEN ANOTHER VEHICLE IN FRONT OF ME AT THE INTERSECTION. AGAIN, MY VEHICLE HAS BEEN SERVICED UNDER THE PREVIOUS RECALL, BUT I CONTINUE TO EXPERIENCE BRAKING PROBLEMS RELATED TO THE ABS. PLEASE RE-OPEN THIS INVESTIGATION AND ISSUE ANOTHER RECALL ON THIS PROBLEM. *TR

UPON BRAKING IF ON A BUMPY ROAD OR HAPPEN TO HIT A POTHOLE THE BRAKES FEEL LIKE THEY ARE DISENGAGED FOR A FEW SECONDS. *TR

I WOULD LIKE TO FILE THIS CLAIM AS THE SAME INCIDENT DESCRIBED BELOW HAPPEN TWO TIMES IN LESS THAN TWO YEARS. THIS IS A BIG SAFETY ISSUE WHICH COULD HAVE BEEN FATAL. -- FIRST EVENT OCCURRED ON 8/17/2012 (ODOMETER 55899). BRAKE TOTALLY FAILED ON A FREEWAY AND ALMOST LOST MY LIFE THAT DAY. TOWED TO THE DEALER AND THEY REPLACED 1) BREAK CYLINDER ASSEMBLY PN#47050-47060, 2)GASKET, BREAK BOOST PN#44785-02060 & 3) BREAK FLUID. WHEN ASKED TO THE DEALER WHAT THE REASON FOR THE FAILURE WAS, WE WERE TOLD THAT THEY DO NOT KNOW THE CAUSE AND FAILED PART WAS SENT TO THE MANUFACTURER FOR INVESTIGATION. WE REQUESTED TO TELL US THE FINDINGS FROM THE MANUFACTURER BUT NEVER HEARD BACK AND SOON AFTER THIS INCIDENT TOYOTA HAD A RECALL FOR BREAKS. -- THE SECOND INCIDENT OCCURRED ON 7/16/2014 (ODOMETER 91965) AND SAME BRAKE FAILURE OCCURRED AGAIN AS DESCRIBED ABOVE.THIS TIME DEALER REPLACED 1) BREAK CYLINDER ASSEMBLY PN#47050-47140, 2) GASKET, BRAKE BOOST PN#44785-02060 & 3) BREAK FLUID. PLEASE NOTE THAT THE SECOND TIME THE BRAKE CYLINDER ASSEMBLY PN# IS DIFFERENT. WE ASKED THE DEALER AGAIN WHAT WAS THE REASON FOR FAILURE OF THE SAME PART AGAIN BUT DID NOT GET A CLEAR ANSWER FROM THEM. WE WROTE SEVERAL EMAILS TO THE DEALER BUT NO RESPONSE YET AS OF TODAY (8/19/14). I AM A VERY UNHAPPY CUSTOMER. WHAT WILL TOYOTA DO IF THIS HAPPENS AGAIN? SOON OUR WARRANTY WILL EXPIRE AND IF THIS HAPPENS AGAIN WHICH IS A TOYOTA'S EXISTING PROBLEM, HOW IT WILL BE COVERED? -- HOPE TO HEAR SOON FROM TOYOTA. *TR

VEHICLE CONTINUED FORWARD WITH NO BRAKING FOR 2 SECONDS AFTER APPLYING THE BRAKES. VEHICLE DID NOT STOP IN TIME TO AVOID STRIKING THE VEHICLE IN FRONT. FRONT BUMPER WAS DENTED AND PUNCTURED BY STRIKING THE TRAILER HITCH ON THE CAR AHEAD. NO DAMAGE TO OTHER CAR. BRAKE BOOSTER WAS REPLACED LAST YEAR UNDER RECALL FOR SAME PROBLEM. REPAIR HAS DONE NOTHING TO CORRECT THE PROBLEM. THE SAME PROBLEM HAS OCCURED INTERMITTENTLY BEFORE AND AFTER THE "FIX". BRAKES MOMENTARILY FAIL TO ACTIVATE EVERY SO OFTEN, WITH NO PARTICULAR PATTERN OR FREQUENCY. DEALER WAS NOTIFIED, AND STATED THAT UNLESS WE CAN DUPLICATE THE PROBLEM FOR THEM, THEY CANNOT PROVIDE ANY REPAIR OR ASSISTANCE. BECOMING UNEASY ABOUT USING THE CAR. WILL PROBABLY TRADE IT IN FOR SOMETHING DIFFERENT, WHICH IS NOT WHAT WE REALLY WANT. WOULD LIKE TO GET IT FIXED, AS WE LIKE THE CAR. NOT TRYING TO BE DIFFICULT, BUT FELT THAT IT SHOULD BE REPORTED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN HE APPLIED THE BRAKES WHILE DRIVING 30 MPH HE HEARD A HARSH ABNORMAL SOUND. THE NOISE WAS HEARD ONE THOUSAND TIMES. THE VEHICLE WAS TAKEN TO A DEALER, WHO DIAGNOSED THAT THE BRAKE BOOSTERS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 50.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 40 MPH OVER A BUMP IN THE ROAD, THE VEHICLE LOST BRAKING CAPABILITY FOR A FEW SECONDS. THE FAILURE OCCURRED EACH TIME THE VEHICLE WAS DRIVEN OVER A BUMP OR POTHOLE. THE DEALER ADJUSTED THE BRAKES, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 48,000. UPDATED 09/02/14*LJ

EXITING FROM THE HIGHWAY, I SLOWED WHILE I APPROACHED A STOP SIGN. AS THE PRIUS WENT OVER A BUMP, DECELERATION WAS INTERRUPTED. THE PRIUS MOMENTARILY SEEMED TO LURCH FORWARD; BUT WITHIN A SHORT TIME BRAKING RESUMED. THIS IS DISTURBING CAR BEHAVIOR. IF THERE WAS A CAR DIRECTLY IN FRONT OF ME, I WOULD HAVE HIT IT. *TR

I BROUGHT MY 2010 PRIUS INTO THE TOYOTA MARIN (CALIFORNIA) DEALER IN JANUARY 2014 IN RESPONSE TO THEIR RECALL RELATED TO PROBLEMS WITH STEPPING ON THE BRAKE AND HAVING THE PRIUS ACCELERATE RATHER THAN STOP. THE CORRECTIVE SOFTWARE WAS PRESUMABLY INSTALLED. FAST FORWARD TO FATHER'S DAY, JUNE 15, 2014. I AM PARKING MY PRIUS FOR A FATHER'S DAY BRUNCH. I'M GOING ABOUT TWO MILES PER HOUR INTO A PARKING SPACE. I PUT MY FOOT ON THE BRAKE. THE CAR ACCELERATES. I MENTALLY DOUBLE CHECK THAT I HAVE MY FOOT ON THE BRAKE. I DO. OUT OF CONTROL, THE CAR JUMPS THE CURB AND SMASHES RIGHT INTO A TREE. MY WIFE ASKS IF MY FOOT IS ON THE BRAKE. I TRIPLE CHECK. IT STILL IS--I HAVEN'T MOVED IT. A WEEK LATER I FEEL THE TRAUMA OF CONSTANTLY VISUALIZING THE POSSIBILITY OF HAVING TRIED TO STOP AT A CROSS WALK AND KILLING A FAMILY ON THE WAY TO THEIR FATHER'S DAY BRUNCH. --IT TOOK THREE DAYS OF CONSTANT CALLING AND DYSFUNCTIONAL EXTENSIONS TO CONNECT WITH A PRIUS CASE MANAGER. THEN SHE INFORMED ME IT WOULD TAKE ME MORE THAN A MONTH TO HAVE MY CAR INSPECTED AND GET AN ASSESSMENT. IF I RENTED A CAR THERE WOULD BE NO ASSURANCE IT WOULD BE COVERED. --THIS PROBLEM HAPPENED AFTER I RESPONDED TO THE RECALL. HOW CAN I TRUST A CAR THAT IS AUTOMATICALLY CRASHING AFTER THAT PRECISE PROBLEM HAS ALLEGEDLY BEEN ADDRESSED? --I JUST RECEIVED (JULY 19, 2014) A LETTER FROM TOYOTA SALES SAYING THE CAR'S BRAKES AND ACCELERATOR WERE TESTED AND "ALL IS FINE." HOWEVER, IN MY AND OTHERS' SIMILAR EXPERIENCES THE SURGE HAPPENS ONLY OCCASIONALLY. WE BOUGHT THE CAR USED, HAVE GONE ABOUT 20,000 MILES WITH IT, AND NEVER HAD THE PROBLEM. SO A TEST EVEN FOR A YEAR AT A TIME IS IRRELEVANT. --MY "ASK": SINCE OTHERS SHARE THIS EXPERIENCE AND IT COULD RESULT IN DEATH, I WANT TOYOTA TO SELL THIS CAR FOR PARTS AND RECALL THE 2010 PRIUS UNTIL A SOLUTION CAN BE FOUND. I AM SHOCKED AT PRIUS' IRRESPONSIBILITY. *TR

BACK IN 2010, WE NOTICED THAT, WHEN BRAKING, THE CAR WOULD LURCH FORWARD. THIS HAPPENED SEVERAL TIMES AT RANDOM. AT THAT TIME, WE TOOK THE CAR IN TO FIX THE PROBLEM. VICTORY TOYOTA IN CANTON, MICHIGAN, TOLD US THAT THERE WAS NOTHING WRONG; THEIR DIAGNOSIS AND COMPUTERS SHOWED THAT NO ERRORS HAD OCCURRED. WE DROVE IT FOR A SHORT TIME, AND IT CONTINUED TO HAVE THE ISSUE. WE TOOK IT BACK IN TO THE DEALERSHIP, THEY AGAIN SAID THAT THERE WAS NOTHING WRONG. THEY SAID THAT THEY TOOK IT FOR A TEST DRIVE, AND NOTHING HAPPENED. WE WERE MADE TO THINK THAT THE ISSUE WAS IN OUR HEADS, SO WE TOOK THE CAR BACK AND TRIED TO DEAL WITH THE ISSUE, EVEN THOUGH IT CONTINUED OVER THE YEARS. FINALLY, THIS YEAR, WE NEARLY GOT INTO TWO SEPARATE ACCIDENTS AS A DIRECT RESULT OF THIS SUDDEN LURCHING FORWARD. I TOOK THE CAR BACK INTO THE SERVICE DEPARTMENT OF VICTORY TOYOTA, AND WAS TOLD BLUNTLY THAT THERE WAS NEVER A RECALL FOR THIS ISSUE, THAT, UNLESS I COULD RECREATE THE PROBLEM WITH A TECHNICIAN IN THE CAR, I WAS MAKING THINGS UP. THAT IS WHAT LEAD TO THIS COMPLAINT. I DID SOME RESEARCH AND FOUND THAT THE CAR HAD INDEED BEEN RECALLED FOR THIS BRAKE ISSUE WITH RECALL ID # 68066. SO THEY LIED ABOUT THE RECALL HISTORY FOR MY CAR. ALSO, RECREATING SOMETHING THAT HAPPENS AT RANDOM DURING A FINITE TIME PERIOD, SUCH AS A TEST DRIVE, IS IMPROBABLE, AND TO MAKE SERVICING THE CAR CONTINGENT ON THAT TEST DRIVE IS LUDICROUS. I AM HOPING THAT, BY LODGING THIS COMPLAINT SOMETHING WILL GET DONE BEFORE MY WIFE, ME, OR/AND SOMEONE ELSE IS/ARE KILLED BECAUSE OF THIS ISSUE. *TR

WHEN BRAKING AT A SLOW SPEED THE CAR WILL SUDDENLY STOP BRAKING, WITH BRAKES STILL BEING APPLIED, WHENEVER A ROUGH SURFACE IS ENCOUNTERED, FOR EXAMPLE BUMPS OR POTHOLES. THIS LOSS OF BRAKING HAPPENS EVERYTIME A ROUGH SURFACE IS ENCOUNTERED DURING BRAKING AND IS EASY TO REPLICATE. *TR

I OWN A 2010 PRIUS, WHEN THE BRAKES ARE APPLIED, THE BRAKE PEDAL IS EVEN WITH THE ACCELERATOR PEDAL. I FIND THIS A DANGEROUS SITUATION. IF I WERE TO APPLY THE BRAKES SUDDENLY, MY FOOT COULD POSSIBLY HIT THE ACCELERATOR PEDAL AND THE BRAKE PEDAL AT THE SAME TIME POSSIBLY CAUSING AN ACCIDENT! I COMPLAINED TO THE TOYOTA DEALER, AND WAS TOLD THE BRAKE PEDAL IS LOWER ON THE PRIUS THEN CONVENTIONAL VEHICLES.I WAS ALWAYS TAUGHT THAT THE BRAKE PEDAL SHOULD NEVER BE AT THE SAME HEIGHT OR BELOW THE ACCELERATOR PEDAL FOR SAFETY REASONS. TOYOTA APPEARS TO IGNORE THIS SAFETY ISSUE. HAVEN'T AUTO MFG. LEARNED ANYTHING WITH GM IGNITION PROBLEM? WHEN IS THE GOVERNMENT GOING TO DO SOMETHING ABOUT THESE AUTO DESIGN DEFECTS? ARE THEY ALWAYS GOING TO WAIT FOR PEOPLE TO GET INTO ACCIDENTS AND POSSIBLY GET KILLED BEFORE THEY ACT? *JS

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE DRIVING IN REVERSE APPROXIMATELY 2 MPH, THE BRAKE PEDAL WAS DEPRESSED AND THE VEHICLE FAILED TO STOP. THE VEHICLE CRASHED INTO A PEDESTRIAN AND ALSO AN OCCUPIED PARKED VEHICLE. THE CONTACT DID NOT SUSTAIN AN INJURY HOWEVER, THE PEDESTRIAN SUFFERED UNKNOWN INJURIES. A POLICE REPORT WAS FILED OF THE INCIDENT. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER FOR DIAGNOSIS. THE TECHNICIAN INFORMED THAT THE BATTERY AMPERAGE WAS DEFECTIVE. THE VEHICLE REMAINED AT THE DEALER FOR FURTHER INVESTIGATION RELATED TO THE BRAKING ISSUE. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 36,000.

EVERY TIME I RUN OVER A ROAD BUMP AT SLOWER SPEEDS (10-20 MPH) WITH LIGHT TAP ON THE BRAKE TO SLOW DOWN, THE CAR ACCELERATES ITSELF AT THE TOP OF THE BUMP. WHEN I SEE THE BUMP, I PUSH THE BRAKE PEDAL TO TRY TO SLOW DOWN BUT IT ACCELERATES INSTEAD AT THE TOP OF THE BUMP. I CALLED TOYOTA DEALER SERVICE DEPT AND REPORTED THE INCIDENT. I AM CONCERNED FOR SAFETY REASONS. THANK YOU. *TR

I OWN A 2010 TOYOTA PRIUS WHICH I BOUGHT IN AUGUST 2013. ON SEVERAL OCCASIONS, APPROXIMATELY, 4-5 TIMES A WEEK, EVERY TIME I RUN OVER A ROAD BUMP OR PATH HOLE AT SLOWER SPEEDS (10-20 MPH), THE CAR ACCELERATES ITSELF. WHEN I SEE THE BUMP OR PATH HOLE, I PUSH THE BRAKE PEDAL TO TRY TO SLOW DOWN BUT IT ACCELERATES INSTEAD. THIS HAS BEEN HAPPENING TO ME SINCE I PURCHASE THE VEHICLE, THE MOST RECENT TIME THIS HAPPENED WAS TODAY, TUESDAY, JUNE 3, 2014. TODAY'S SURGE IN THE ACCELERATION WAS MORE THAN BEFORE. I IMMEDIATELY CALLED TOYOTA AND REPORTED THE INCIDENT. I UNDERSTAND THIS HAS BEEN AN ISSUE SINCE THIS CAR WAS RELEASED IN 2009-2010 AND MANY OTHER OWNERS REPORTED IT IN THE PAST. I AM CONCERNED FOR SAFETY REASONS, KINDLY HAVE TOYOTA ADDRESS THIS ISSUE AS SOON AS POSSIBLE. THANK YOU. *TR

WHILST STOPPED AT A TRAFFIC LIGHT, BEHIND A SUBURU, THE BRAKE FAILED AND HIT THE SUBURU. (THIS WAS NOT THE FIRST TIME THE BRAKE FAILED, BUT FORTUNATELY THERE WERE NO OTHER CARS INVOLVED WHEN THE CAR DID NOT STOP. THE DRIVER BELIEVED THAT BLACK ICE WAS INVOLVED, BUT AFTER THE INCIDENT WITH THE SUBURU, REALIZED THAT IT WAS BRAKE FAILURE.) BELIEVING THAT THE AUTO COULD NO LONGER BE TRUSTED, IT WAS SOLD. TOYOTA INSISTED IT WAS DRIVER ERROR., AND CLAIMED THAT THERE WAS NO FAULT IN THE BREAKING SYSTEM. *TR

2010 TOYOTA PRIUS 2, DEPRESSING BRAKE AS I APPROACH STOP SIGN, HLT A SMALL BUMP OR POT HOLE . CAR BRAKES RELEASE EVEN THOUGH MY FOOT IS STILL ON THE BRAKE. I LURCH FORWARD AND HAVE TO STOMP ON THE BRAKES. IF THERE WAS A CAR IN FRONT OF ME OR A PEDESTRIAN, I WOULD PROBABLY WOULD HAVE HIT THEM. I THOUGHT THIS PROBLEM WAS FIXED IN THE LAST RECALL . EXPERIENCING IT EVERYDAY, I THOUGHT THIS PROBLEM WAS FIXED IN THE LAST RECALL !!!!!! *TR

DRIVING DOWN STREET SLIGHT DOWN HILL , DEPRESSING BRAKE AS I APPROACH STOP SIGN, HLT A SMALL BUMP OR POT HOLE IN STREET. CAR BRAKES RELEASE EVEN THOUGH MY FOOT IS STILL ON THE BRAKE. I LURCH FORWARD AND HAVE TO STOMP ON THE BRAKES. IF THERE WAS A CAR IN FRONT OF ME OR A PEDESTRIAN, I WOULD PROBABLY WOULD HAVE HIT THEM. I THOUGHT THIS PROBLEM WAS FIXED IN THE LAST RECALL !!!!!! *TR

WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. THIS HAPPENS ON ALMOST A DAILY BASIS AND HAS BEEN EXPERIENCED BY ALL DRIVERS OF THE CAR. *TR

CONTINUAL BRAKING PROBLEMS WITH MY CAR. AT LOW SPEEDS APPLYING THE BRAKES ON A SLIPPERY OR BUMPY SURFACE, THERE IS A COMPLETE LACK OF BRAKING FOR A VERY SHORT PERIOD OF TIME. THE CAR SEEMS TO ACCELERATE. THIS WAS SUPPOSEDLY FIXED BY A TOYOTA RECALL. (SSC AOB) WHICH I HAD PERFORMED. STILL HAVE THE PROBLEM. I HAVE COMPLAINED MANY TIMES TO DIFFERENT TOYOTA SERVICE DEPARTMENTS. THE ANSWER IS ALWAYS THEY CANNOT DUPLICATE THE PROBLEM. (THIS LAST TIME THEY TOLD ME THAT, AND THEY DIDN'T EVEN ROAD TEST IT.) HAVE COMPLAINED TO TOYOTA CORPORATE 5/26/2010, FILE #[XXX]. THEY CALLED ME BACK, ON 6/7/2010, STILL NO FIX YET, WILL CONTACT ME WHEN A FIX IS AVAILABLE. I USUALLY DRIVE THIS CAR, MY WIFE DROVE IT TODAY, AND IT HAPPENED TO HER. SCARED HER TO DEATH, DOES NOT WANT TO DRIVE THE CAR ANYMORE. HELP! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THIS HAS OCCURRED ON MULTIPLE INCIDENTS. THIS CAR DOES NOT STOP PROPERLY ON ROUGH ROADS. WHEN HITTING A POTHOLE, BUMP, MANHOLE COVER, ROUGH ROAD WHILE APPLYING THE BRAKES, INSTEAD OF STOPPING, THE CAR SURGES FORWARDS APPROXIMATELY 5-10 FEET AS THOUGH THERE WERE NO BRAKES. EVENTUALLY, THE BRAKES WORK AND THE CAR STOPS. BUT IT CAN BE REALLY SCARY. I HAVE TAKEN IT TO TOYOTA SEVERAL TIMES, BUT THEY CANNOT "REPLICATE THE INCIDENT." BASICALLY, I THINK THEY DRIVE IT AROUND THE BLOCK AND IT DOESN'T HAPPEN. IT IS ALWAYS WORSE WITH THE SUMMER TIRES VS THE STUDDED WINTER TIRES. THEY SAY IT HAS TO DO WITH THE REGEN BRAKES SWITCHING TO THE ANTI-LOCKS, BUT I REGULARLY DRIVE RENTAL CARS WITH ANTI-LOCKS FOR WORK IN OTHER CITIES, AND I KNOW WHAT ANTI-LOCKS FEEL LIKE. I HAVE NEVER FELT THE "CHATTER" ONE FEELS WHEN THE ANTI-LOCKS KICK ON. I DO NOT BELIEVE THE ANTI-LOCKS WORK PROPERLY ON THIS CAR. ON MAY 3, 2012, I HAD TO REPLACE THE RIGHT REAR BRAKE (ROTOR, PLATE, PADS) DUE TO UNEXPECTED CORROSION. MY CAR HAD ~17-18,000 MILES ON IT AND WAS ONLY 1.5 YEARS OLD! I HAVE NEVER HAD TO DO THIS ON ANY OTHER CAR. NOW AT 27, 000 MILES, MENDENHALL TOYOTA SAYS I NEED TO REPLACE THE REAR BRAKES AGAIN . I JUST REPLACED THE FRONT BRAKE PADS LAST WEEK. BUT THERE IS A NASTY SQUEAL THAT I REPORTED TO THEM LAST WEEK AND THEY DID NOTHING. EITHER THEY ARE RIPPING ME OFF OR THE BRAKES ON THESE CARS ARE DEFECTIVE AND DANGEROUS. PLEASE DO SOMETHING. TOYOTA REFUSES TO LISTEN. *JS

APPLYING BRAKES, EITHER GRADUALLY OR WITH FORCE, WHILE FRONT LEFT OR FRONT RIGHT TIRE TRAVELS OVER A POTHOLE OR SUNKEN MANHOLE COVER RESULTS IN TEMPORARY (< 1 SECOND) COMPLETE LOSS OF BRAKING POWER. BRAKE PEDAL IS DEPRESSED THROUGH THE ENTIRE DURATION OF THE INCIDENT. LOSS OF BRAKING POWER RESULTS IN DRIVER APPLYING BRAKE WITH MORE FORCE. WHEN BRAKES RESUME POWER, THE INCREASED FORCE RESULTS IN A SUDDEN DROP IN SPEED. THIS INCIDENT INCREASES THE RISK OF A REAR END COLLISION EITHER TO A VEHICLE IN FRONT OR FROM A VEHICLE BEHIND THE PRIUS. *TR

WHEN APPLYING LIGHT TO MODERATE BRAKING IN PREPARATION TO MAKE A RIGHT TURN, I WENT OVER SOME BUMPY PAVEMENT AND THE CAR SEEMED TO LURCH FORWARD. IT WAS PROBABLY A LOSS OF BRAKING RATHER THAN ACTUAL ACCELERATION, BUT IT WAS VERY DISCONCERTING AND I'M LUCKY IT DIDN'T CAUSE AN ACCIDENT. I NOW HAVE OVER 49,000 MILES ON THE CAR AND THIS HAS HAPPENED ON QUITE A FEW OCCASIONS. I KNOW THERE WAS A RECALL ON SOME 2010 PRIUS VEHICLES FOR THIS PROBLEM BUT MY CAR WAS NOT RECALLED. MY DEALER SAYS THERE IS NO "SOFTWARE FIX" FOR THIS PROBLEM. I FIND IT UNACCEPTABLE THAT TOYOTA DOESN'T HAVE A SOLUTION FOR THIS AS IT IS A REAL SAFETY ISSUE. IT'S JUST PURE LUCK THAT I HAVEN'T BEEN INVOLVED IN AN ACCIDENT WITH POSSIBLE INJURIES OR WORSE. I INTEND TO PURSUE THIS AGAIN WHEN I BRING THE CAR IN FOR THE 50,000 MILE SERVICE AND INVERTER RECALL, BUT I'M NOT VERY HOPEFUL. MAYBE IF MORE OWNERS LODGE A COMPLAINT ON THIS SITE, TOYOTA WILL BE FORCED TO CORRECT THIS ISSUE. *TR

BRAKES ON VEHICLE OCCASIONALLY MOMENTARILY DISENGAGES WHEN I HIT A BUMP, PARTICULARLY ON A SLIPPER SURFACE, WHILE BRAKING AT LOW OR MODERATE BRAKING. THIS HAS HAPPENED MULTIPLE TIMES. IT IS VERY OBVIOUS WHEN THIS HAPPENS. RECENTLY IT HAPPENED WITH MY WIFE IN THE CAR, I WAS BRAKING MODERATELY, THE BRAKES FULLY DISENGAGED FOR ABOUT A SECOND, WHEN THEY DID I INCREASED PRESSURE ON THE BRAKE PEDAL AND THE CAR SEVERELY LURCHED WHEN THE BRAKES RE-ENGAGED. THE 2010 PRIUS HAD A RECALL FOR THIS, BUT MINE IS LATE IN THE MODEL YEAR AND WAS NOT SUBJECT TO THAT RECALL. TOYOTA USA AND THE DEALER, OF COURSE, SAYS THERE IS NOT A PROBLEM AND THAT THEY CANNOT DO ANYTHING ABOUT IT. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN BRAKING TO A STOP, ABRUPT FORCE HAD TO BE APPLIED TO THE BRAKES IN ORDER FOR THE VEHICLE TO RESPOND. THE VEHICLE WOULD SLIDE ABNORMALLY AND THERE WAS A DECREASE IN BRAKING DISTANCE. THE VEHICLE WAS INCLUDED IN NHTSA CAMPAIGN ID NUMBER:13V235000 (SERVICE BRAKES) AND WAS SERVICED HOWEVER, THE FAILURE WAS NOT CORRECTED. THE MANUFACTURER WAS MADE AWARE OF THE BRAKE FAILURE NUMEROUS TIMES. THE VEHICLE WAS NOT FULLY REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 10000.

PLEASE LET ME STATE THAT I AM EXTREMELY HAPPY WITH THE DEALERSHIP THAT I BOUGHT THE CAR FROM. ALL SERVICES FROM OIL CHANGES TO REPAIRS HAVE DONE BY THIS DEALER ONLY. BUT EVER SINCE I PURCHASED THIS VEHICLE, I HAVE BEEN CONSTANTLY COMPLAINING ABOUT A STRANGE BRAKING ISSUE. WHEN I AM TRAVELING 25 MPH OR ABOVE AND HIT ANY KIND OF IMPERFECTION IN THE ROAD ( IE. RAILROAD TRACK, DIP, POTHOLE, MANHOLE COVER ETC.) MY BRAKES DISENGAGE FOR A SPLIT SECOND. I WILL STILL HAVE MY FOOT ON THE BRAKE AND GO OVER IMPERFECTION AND FOR A BRIEF SECOND THE CAR SURGES FORWARD RAPIDLY AND THEN THE BRAKE ENGAGES AGAIN. I HAVE COMPLAINED ABOUT THIS MORE THAN 3 TIMES. ALL THREE TIMES THE DEALER SAYS THAT THEY CAN NOT REPEAT THIS ISSUE. I NOW HAVE 70,000 MILES ON THE CAR AND THIS IS STILL HAPPENING. ALTHOUGH I AM THE PRIMARY USER OF THIS VEHICLE, MY WIFE REFUSES TO DRIVE THE CAR CALLING IT UNSAFE. TODAY 3.25.2014 I HAVE DROPPED OFF THE CAR AT THE DEALER FOR A RECALL AND I HAVE MENTIONED THE PROBLEM AGAIN, MY SERVICE ADVISER IS NOW TELLING ME THAT THIS RECALL (SOFTWARE UPDATE FOR MOTOR GENERATOR ECU AND POWER MANAGEMENT ECU) SHOULD TAKE CARE OF THE PROBLEM.) HE EXPLAINED THAT THEY ARE UPDATING THE SOFTWARE BRAKE STOP TECHNOLOGY. THE ABOVE RECALL LETTER EXPLAINS THE CONDITION THAT IS BEING REMEDIED AND DOES NOT TRANSLATED TO THE CONDITIONS THAT I AM COMPLAINING ABOUT. PLEASE HELP ME WITH THIS SERIOUS ISSUE. *TR

SINCE WE HAVE HAD THE 2010 PRIUS, WHEN WE DRIVE IT OVER A BUMP OR ROUGH ROAD, USUALLY AT A LOW SPEED, AND APPLY THE BRAKE SIMULTANEOUSLY, THE CAR SEEMS TO ACCELERATE BRIEFLY. I TOLD MY TOYOTA DEALER ABOUT IT THE FIRST TIME WE BROUGHT IT IN FOR SERVICE, BUT THEY SAID THEY'D NEVER HEARD OF SOMETHING LIKE THIS. I TRY TO AVOID BRAKING WHEN I GO OVER BUMPS, BUT I WORRY THAT ONE DAY I WILL HIS SOMETHING OF SOMEONE ON THE OTHER SIDE. THE WEIRD ACCELERATION CAN BE FELT BY THE PASSENGER TOO. *TR

WHEN MY HUSBAND WAS DRIVING OUT OF THE PARKING LOT IN CHARLOTTE ON FRIDAY 02/07, ALL 3 LIGHTS - BRAKE, ABS, SKID CONTROL LIGHTS ALL WENT UP. WHEN HE STEPPED ON THE BRAKE, HE DIDN'T FEEL ANYTHING. LUCKILY HE WAS JUST GETTING OUT OF THE PARKING LOT, SO HE WAS DRIVING SLOWLY. WHEN HE STEPPED ALL THE WAY DOWN ON THE BRAKE, IT HAD THIS LOUD METAL RATTLING NOISE, AND HE WAS ABLE TO STOP. WE TOWED THE CAR TO TOWN AND COUNTRY TOYOTA ON SATURDAY, THE ASSISTANT SERVICE MANAGER SAID HE'S NEVER SEEN IT BEFORE, AND THE ERROR CODE SHOWN DURING DIAGNOSIS IS A CODE THEY'VE NEVER SEEN. THE MESSAGE ASKED THEM TO CONTACT TOYOTA TECHNICAL SERVICE. ON MONDAY 02/10, THE DEALER CALLED AND TOLD US THAT IT WILL COST OVER $4500 TO FIX IT. WE BOUGHT THE CAR IN FEB 2011 AS BRAND NEW CAR, SO IT'S JUST 3 YEARS OLD. I THEN CONTACTED TOYOTA CUSTOMER SERVICE, AND REQUESTED THAT TOYOTA COVERS THE REPAIR. I WAS TOLD THAT THERE IS NO RECALL PROGRAM RELATED TO THIS PROBLEM, AND THAT IF I RUN INTO THE SAME SITUATION AGAIN, OR OTHER PEOPLE RUN INTO THE SAME ISSUE, THEN TOYOTA MIGHT CONSIDER A RECALL, AND WOULD REFUND ME FOR THE REPAIR. THIS IS A VERY DANGEROUS SITUATION THAT I HOPE I'LL NEVER RUN INTO IT AGAIN EVER! IT JUST SEEMS TOYOTA IS VERY COLD AND INDIFFERENT TO PEOPLE'S SAFETY. *TR

THE ABS/BRAKE/STABILITY LIGHTS ARE "ON" PRIUS DASH. THE BRAKE LOST PRESSURE AND MUSHY. THE BRAKE MUST BE PUMPED A FEW TIMES TO GET PRESSURE AND TO STOP THE CAR. EITHER THIS IS ABS ACCUMULATOR(JUST FOUND OUT THERE IS A RECALL WHILE GETTING DEALER APPOINTMENT) FAILURE OR BRAKE MASTER CYLINDER FAILURE. THERE IS NO FLUID LEAK VISIBLE OUTSIDE OR INDICATOR LIGHT BUT THE FLUID IS ALMOST EMPTY IN THE RESERVOIR. I DON'T HAVE DEALER DIAGNOSIS AT THIS POINT YET. I'M NOT SURE IF THE ACCIDENT I HAVE ON 1/27/2014 THAT I'VE REAR-ENDED ANOTHER VEHICLE WHILE TRAVELING ABOUT 30-35MPH AND TRIED TO STOP BUT THE CAR DID NOT STOP AND BUMPED INTO THE CAR IN FRONT. FORTUNATELY, THERE IS INJURY OR MAJOR DAMAGES. AT THAT TIME I DIDN'T THINK OF IT THAT THE BRAKE MAY HAVE ISSUE OR NOT BUT THINKING BACK THE BRAKE DIDN'T HAVE ENOUGH BITE TO STOP EVEN THOUGH THE CAR IS TRAVELING SLOW ENOUGH AND THERE IS AMPLE DISTANCE. AS FAR AS I REMEMBER I DO NOT FEEL THE ABS KICKING IN EITHER. HOPEFULLY, I'LL FIND OUT MORE FROM DEALER SERVICE. THANKS. *TR

ON OCTOBER 10TH, 2013 AT 7 PM, I NOTICED SEVERAL BRAKE LIGHTS, ABS, AND SLIDING SIGN LIGHT CAME ON WHEN I STARTED MY CAR. I THOUGHT IT WAS SOME KIND OF ELECTRICAL GLITCH SO I TURNED MY CAR OFF AND TURNED IT BACK ON. THE LIGHTS STAYED SAME. MY HUSBAND WHO SAT ON THE PASSENGER SIDE LOOKED INTO THE MANUAL BOOK AND TOLD ME THOSE LIGHTS WERE INDICATED FOR BRAKE SYSTEM. WE DECIDED TO GO HOME TO FIGURE OUT WHAT WE NEEDED TO DO. AS SOON AS I STARTED TO DRIVE, I NOTICED BRAKE PEDAL WAS MUCH LOWER THAN IT USUALLY IS AND ALSO NOTICED BRAKE WAS NOT WORKING. MY CAR KEPT MOVING EVEN WHEN I PRESSED THE BRAKE ALL THE WAY. AT THAT MOMENT, I KNEW I HAD TO TAKE MY CAR TO DEALER RIGHT AWAY. THERE WERE NO WARNING SIGNS OR NOISE FOR A DRIVER TO NOTICE BEFORE THE WHOLE BRAKE SYSTEM WAS COMPLETELY FAIL TO PERFORM. IN JANUARY 2013, TOYOTA RECALLED MANY PRIUS IN SAME MODEL AND SAME YR AS MINE FOR TOTAL BREAK SYSTEM FAILURE. EVEN THOUGH MY VIN NUMBER WAS NOT UNDER THEIR RECALL LIST, MY CAR'S BRAKE SYSTEM BROKE DOWN COMPLETELY TO FUNCTION DUE TO SAME REASONS TOYOTA RECALLED MANY PRIUS 2010 THIS YEAR. TOYOTA REFUSED TO FIX MY CAR UNDER THEIR RECALL SYSTEM WARRANTY BECAUSE MY VIN NUMBER IS NOT UNDER THEIR RECALL LIST. TOYOTA DEALER CHARGED ME $4300 TO REPLACE THE WHOLE BRAKE SYSTEM FOR MY CAR AND IT TOOK 4 WEEKS TO FIND THE PARTS IN NORTH AMERICA TO FIX MY CAR. IT COST ME ANOTHER $1000 TO RENT A CAR WHILE MY PRIUS AT TOYOTA DEALER TO FIND THE PARTS TO FIX IT. I WAS FORTUNATE ENOUGH THAT MY BRAKE SYSTEM DIDN'T BLOW OUT ON ME WHEN I WAS DRIVING 75MPH ON FREEWAY. I'M SURE THERE ARE MANY OTHER PRIUS 2010 HAVE BRAKE SYSTEM FAILURE LIKE MINE EVEN THOUGH THEY WERE NOT UNDER THEIR RECALL LIST. *TR

THE CAR IN FRONT OF ME STOPPED ABRUPTLY AND I SLAMMED ON MY BRAKES. I HELD THEM TO THE FLOOR AND THE CAR CONTINUED AT THE SAME SPEED INTO THE REAR END OF THE CAR IN FRONT OF ME. I WAS AT LEAST 1 AND 1/2 CAR LENGTHS AWAY WHEN I SLAMMED ON THE BRAKES. I HAVE BEEN TOLD BY STATE FARM INSURANCE THAT THERE WAS A RECALL ON THE 2010 PRIUS. I WAS TOLD MY MY TOYOTA CAR DEALER THAT MY CAR WAS BUILT IN MARCH 2010 AND THUS WAS NOT PART OF THE RECALL. I PURCHASED THIS CAR IN 11/13. IS THERE A WAY TO VERIFY EXACTLY WHICH DAY MY CAR WAS BUILT? *TR

THIS HAPPENED MORE THEN ONCE, ALL PRETTY MUCH THE SAME WAY. WHILE DRIVING APPROXIMATELY 30 MPH, APPLYING THE BRAKES COMING TO A STOP AND TRAVELING OVER A ROUGH ROAD THE BRAKES FEEL LIKE THEY RELEASE AND THE VEHICLE DOES NOT STOP. AFTER THE VEHICLE PASSES THE ROUGH ARE I HAVE TO RELEASE THE BRAKES AND REAPPLY PRESSURE TO THE BRAKE PEDDLE FOR THE VEHICLE BRAKES TO REENGAGE AND STOP THE FORWARD MOMENTUM. LAST MONTH WHEN I TOOK THE VEHICLE TO DEALER IN OLYMPIA WA, I ASKED THEM TO CHECK FOR ANY RECALLS AND MAKE A NOTE OF THE ISSUE. THIS ISSUE HAS ALMOST CAUSE AN ACCIDENT. *TR

I BELIEVE THE NHTSA SHOULD INVESTIGATE WHETHER TOYOTA HAS UNDERSTATED THE NUMBER OF 2010 PRIUS CARS WITH POTENTIALLY FAULTY BRAKE ACCUMULATOR PUMPS. THE COMPANY RECALLED THOUSANDS OF THE CARS MANUFACTURED BETWEEN JUNE AND OCTOBER, 2009. MY DEALER RECENTLY TOLD ME THAT MY 2010 PRIUS, MANUFACTURED IN DECEMBER, 2009 ? JUST TWO MONTHS LATER ? HAS ESSENTIALLY THE SAME PROBLEM. THEY INFORMED ME THAT THIS IS A ?SAFETY CONCERN? AND THAT THE PUMP SHOULD BE REPLACED ?AS SOON AS POSSIBLE,? AT A COST OF OVER $4,000. BUT BECAUSE MY CAR WAS MANUFACTURED TWO MONTHS AFTER THE LAST CARS COVERED IN THE RECALL, THEY HAVE REFUSED TO PAY FOR THE REPLACEMENT. I AM VERY DOUBTFUL OF THE IDEA THAT PROBLEM AFFECTING MY CAR IS DIFFERENT FROM THE DEFECT RESULTING IN THE RECALL. FIRST, THE KEY ISSUE IS ESSENTIALLY IDENTICAL: CONTAMINATED FLUID THAT COULD RESULT IN A LOSS OF BRAKING POWER. SECOND, THE CAR IS THE SAME MODEL AND YEAR AS THOSE RECALLED, JUST MANUFACTURED A COUPLE OF MONTHS LATER. THIRD, THIS SORT OF REPAIR ? THE NEED TO REPLACE A SINGLE, VERY EXPENSIVE COMPONENT LESS THAN FOUR YEARS AFTER PURCHASE ? OUGHT TO BE RARE. IF IT?S NOT, THIS SUGGESTS A SYSTEMATIC DIFFICULTY. *TR

REVERSING INTO MY DRIVEWAY WHICH IS A SLOPE DRIVEWAY. TRYING TO GO SLOW AS POSSIBLE. WHEN TRY TO STOP THE CAR WITH BRAKES THE CAR DID NOT STOP. CAUSING A CRASHED THROUGH MY GARAGE DOOR WHICH WAS CLOSE AT THAT TIME. *TR

UPON BRAKING OVER A BUMP, POTHOLE, WET LEAVES AND/OR ANY COMBINATION OF THE AFOREMENTIONED CIRCUMSTANCES, THE PRIUS ACCELERATES FORWARD, THUS CREATING A VERY UNSAFE DRIVING CONDITION. SINCE I ORIGINALLY PURCHASED THE VEHICLE, IT HAS DONE THIS ON NUMEROUS OCCASIONS. I DO NOT FEEL SAFE DRIVING THIS VEHICLE AND AM AFRAID THAT THIS BRAKING ISSUE MAY RESULT IN AN ACCIDENT THAT OTHERWISE WOULD HAVE BEEN A NON-ISSUE FOR ANY OTHER VEHICLE. IN MY 19+ YEARS OF DRIVING, I HAVE NEVER HAD A VEHICLE DO THIS WHILE BRAKING. I, THEREFORE, IMPLORE THE NTSB TO DUTIFULLY CARRY OUT ITS MISSION STATEMENT OF PROTECTING MOTORISTS BY FORCING TOYOTA TO RECALL SAID VEHICLE IN ORDER TO PROPERLY REMEDY THIS ISSUE BEFORE PREVENTABLE ACCIDENTS OCCUR AND LIVES ARE POTENTIALLY LOST. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE VEHICLE WAS INCLUDED IN AND REPAIRED UNDER NHTSA CAMPAIGN ID NUMBER: 13V235000 (SERVICE BRAKES). AFTER THE REPAIR WAS PERFORMED, THE CONTACT WAS DRIVING APPROXIMATELY 25 MPH WHEN THE BRAKE PEDAL WAS ABNORMALLY TRAVELED TO THE FLOOR BOARD, AND THE BRAKE AND ABS LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS WHERE THE TECHNICIAN STATED THAT THE BRAKES WOULD HAVE TO BE BLED. THE BRAKES WERE BLED HOWEVER, THE FAILURE PERSISTED. THE DEALER ALSO REPLACED THE BRAKE BOOSTER AND MASTER CYLINDER TWICE. THE BRAKE POWER STROKE SENSOR WAS ALSO REPLACED BUT NONE OF THE REPAIRS WERE ABLE TO CORRECT THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 93,000. UPDATED 12/24/13*LJ

2010 TOYOTA PRIUS. CONSUMER WRITES IN REGARDS TO UNSATISFACTORY CUSTOMER SERVICE AT DEALERSHIP. *SMD THE CONSUMER FELT SHE WAS DEALT WITH IN A CAVALIER, DISRESPECTFUL MANNER WITH NO REGARD FOR HER TIME, AFTER MAKING AN APPOINTMENT AT THE DEALER FOR A RECALL ISSUE. THE VEHICLE WAS NOT READY AT THE TIME SHE WAS PROMISED IT WOULD BE.

VEHICLE ACTIVATES ABS WHILE STOPPING AND BRAKE DISENGAGES, CAUSING VEHICLE TO NOT STOP WHEN BRAKES ARE APPLIED UNLESS BRAKES ARE REAPPLIED, POTENTIALLY LEADING TO ACCIDENTS DUE TO BRAKING FAILURE. DEALERSHIP IS NOT ADDRESSING THE ISSUE IN A TIMELY MANNER. DELAYING THIS RECALL MONTHS MIGHT LEAD TO ACCIDENTS AFFECTING ALL PASSENGERS, INCLUDING CHILDREN. CONTINUED DELAY OF THIS MATTER COULD LEAD TO LEGAL ACTION DUE TO AN INABILITY ON BEHALF OF THE TOYOTA COMPANY AND DEALERSHIPS TO PROMPTLY FIX A SEVERE AND DANGEROUS PROBLEM. *TR

COMING TO A STOP LIGHT, I APPLIED THE BRAKES. THIS HAS BEEN AN ONGOING ISSUE WITH MY CAR THAT WHEN APPLYING THE BRAKES AND A BUMP IN THE ROAD IS DETECTED, THE CAR SUPPOSEDLY SWITCHES TO ABS BRAKING. THE NET EFFECT OF IT IS THAT THE BRAKES TEMPORARILY DISENGAGE CAUSING THE CAR TO ACCELERATE FOR A BRIEF PERIOD UNTIL YOU REAPPLY THE BRAKES AND EVENTUALLY COME TO A STOP. SO AS A RESULT, THE FROM THE MOMENT YOU APPLY THE BRAKES TO THE TIME YOU STOP, THERE IS A "LURCHING FORWARD" OF ABOUT 5 FEET UNDER WHICH YOU HAVE NO CONTROL OVER THE CAR. THAT IS QUITE SCARY SINCE IF PER CHANCE A PERSON WERE CROSSING THE ROAD WHILE YOUR CAR HIT A BUMP IN THE ROAD, YOUR VEHICLE COULD THEORETICALLY HIT THE PERSON BEFORE THE BRAKES HAD A CHANCE TO KICK IN. I'VE CHECKED THE BLOGS AND HAVE NOTICED THAT PEOPLE WITH PRIUSES FROM VARIOUS YEARS HAVE REPORTED THE SAME PROBLEM. I NOTICED THIS PROBLEM EARLY ON IN MY OWNERSHIP OF THE CAR, AND ACTUALLY ASKED THE DEALER TO FIX THE PROBLEM. THEY REPORTED TO ME THAT EVERYTHING WAS WORKING PROPERLY. I THEN ASKED THEM TO TEST DRIVE IT FOR A WHILE TO REPRODUCE THE PROBLEM. THEY HAD MY CAR FOR A WEEK AND SUPPOSEDLY WERE UNABLE TO REPRODUCE THE PROBLEM. THERE WAS AN ABS RECALL BY PRIUS AND THEY SUPPOSEDLY APPLIED THE FIX TO MY CAR, BUT I HAVE SINCE NOTICED THE SAME ISSUE. *TR

THE ABS SYSTEM ON MY 2010 PRIUS SEEMS TO RELEASE THE BRAKE WHEN APPLIED ON ROUGH SURFACES GOING DOWNHILL WHICH GIVES A SENSE OF ACCELERATION AND LACK OF VEHICLE CONTROL. THE SAME EFFECT OCCURS WHEN DRIVING ON SOME LEVEL SURFACES. I HAVE RECENTLY READ DOZENS OF ACCOUNTS ABOUT THE PRIUS BRAKES ACTING THIS WAY AS FAR BACK AS 2006 MODELS. I'M AM NOW CONCERNED ABOUT THE BRAKE SYSTEM INTEGRITY WHEN I DRIVE AND FEEL STRONGLY THAT THE NHTSA SHOULD INITIATE AN IN DEPTH INVESTIGATION INTO THIS SITUATION. *TR

CAR FAILS TO STOP ON BUMPY SURFACES. STREET UNDER CONSTRUCTION WAS COVERED WITH METAL PLATES WITH BUMPY SURFACE (THE RIDGES ARE ARRANGED IN SQUARES AND I THINK ARE LESS THAN AN INCH HIGH; THEY ARE NOT THE PLATES WITH A SMOOTH SURFACE). AS THE CAR WENT OVER THE PLATES, BRAKING FAILED. THE PLATES ENDED A SHORT DISTANCE BEFORE THE TRAFFIC SIGNAL AND REGULAR PAVEMENT RESUMED. I WAS BARELY ABLE TO STOP IN TIME. I CHECKED ONLINE AND I SEE THAT OTHER PEOPLE HAVE THE SAME PROBLEM. SOMEONE SUGGESTED THE ANTI-LOCK BRAKING SYSTEM. THIS HAPPENED ON S. LEIMERT BLVD. APPROACHING VERNON, BUT THESE PLATES ARE ALL OVER THIS PART OF LOS ANGELES. *TR

BOUGHT THIS CAR CERTIFIED USED FROM TOYOTA DEALER IN MID-MAY 2013. FIRST PRIUS I'VE OWNED, AND NOT USED TO DRIVING IT, SO THE FIRST COUPLE TIMES IT 'LURCHED FORWARD' WITH THE BRAKES ON, I WAS SURPRISED, BUT FIGURED IT WAS JUST RELATED TO THE 'HYBRID'. IT HAPPENED AGAIN LAST WEEK AT A STOP SIGN WITH ROUGH ROAD - BRAKING, HIT BUMPS, AND BRAKES DISAPPEAR! TOOK IT INTO DEALER THIS MORNING, AND THEY'RE SAYING IT'S 'NORMAL'. THEN I START RESEARCHING AND WHILE CAR IS NOT INCLUDED IN ANY RECALLS, IT'S THE SAME PROBLEM INVESTIGATED IN NTSB 10V039000. EXACTLY! CAR IS STILL AT DEALER, AS I HAVE ASKED TO SPEAK TO SERVICE MGR. AND JUST IN NEWS TODAY, SUPREME COURT IS ALLOWING CALIF 2010 PRIUS OWNERS TO SUE TOYOTA OVER A BOGUS FIX FOR THIS PROBLEM. NOT SURE WHAT TO DO, BUT NOT GOING TO LET UP ON THIS. HALF DOZEN TIMES IN 4 MONTHS THIS HAS HAPPENED, AND I LIKE THE FEELING LESS EVERY TIME. ANYTHING I CAN DO? (WHEN YOU ALL GET BACK TO WORK). *TR

RECEIVED SAFETY RECALL NOTICE FROM TOYOTA MOTOR SALES USA. MADE APPOINTMENT WITH LIBERTYVILLE TOYOTA (AUTONATION TOYOTA LIBERTYVILLE IN LIBERTYVILLE, ILLINOIS), THE DEALER FROM WHOM I BOUGHT THE CAR. ON 9/13/13 LIBERTYVILLE TOYOTA INSPECTED MY VEHICLE AND ADVISED ME THAT THE SERIAL NUMBER ON THE BRAKE BOOSTER PUMP ASSEMBLY WAS ON THE RECALL LIST THAT REQUIRED REPLACEMENT. I WAS TOLD NONE WERE IN STOCK BUT IT SHOULD TAKE 2 OR 3 DAYS FOR THE ORDER TO COME AND THAT I WOULD BE PHONED "AROUND THE MIDDLE OF NEXT WEEK." NO CALL CAME SO I PHONED LIBERTYVILLE TOYOTA ON 9/24/13. THE RECEPTIONIST DIRECTED MY CALL TO THE PARTS DEPARTMENT. THE PARTS PERSON WHO TOOK MY CALL TOLD ME THAT THE PART WAS NOT IN THEIR STOCK AND THAT THERE WAS NO ESTIMATED TIME OF ARRIVAL (ETA) FOR THE PART. HE SAID HE HAD NO IDEA WHETHER OR WHEN THE PART WOULD BE AVAILABLE. I ASKED TO SPEAK TO THE MANAGER SO HE TRANSFERRED ME TO THE SERVICE MANAGER ([XXX]). [XXX] DIDN'T PICK UP SO I LEFT A FAIRLY DETAILED MESSAGE AND ASKED HIM TO CALL ME BACK. IT'S NOW 9/30/13 AND I HAVE NOT BEEN CALLED BY [XXX] OR ANYONE AT LIBERTYVILLE TOYOTA. IN THE MEANTIME I'M DRIVING A VEHICLE THAT IS SUBJECT TO A SAFETY RECALL, THE SEVERITY OF WHICH I HAVE NO IDEA, AND I'M PLANNING A TRIP WITH THE VEHICLE THAT WILL ENTAIL APPROXIMATELY 3,000 MILES OF DRIVING. WHAT AM I TO DO? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS.THE CONTACT STATED THAT WHILE DRIVING 25 MPH OVER A ROAD BUMP AND THE VEHICLE LUNGED FORWARD ABNORMALLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION BUT THEY COULD NOT DIAGNOSE THE CAUSE OF FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 36,000.

THIS INCIDENT HAS OCCURRED NUMEROUS TIMES SINCE PURCHASING THE CAR, BUT IT WASN'T UNTIL LAST WEEK (9/6/2013) THAT I BECAME TERRIFIED AS I ALMOST HIT ANOTHER VEHICLE IN FRONT OF ME. WHENEVER MY PRIUS RUNS OVER A POTHOLE, BUMP, UNEVEN SURFACE, OR DEEP MANHOLE COVER AS I AM BRAKING TOWARDS AN INTERSECTION TO COME TO A STOP (FOR ME, ALL THESE INCIDENTS OCCURRED WHEN I APPROACHED AN INTERSECTION) THE BRAKES STOP WORKING FOR A BRIEF MOMENT AND SUDDENLY MY CAR JERKS FORWARD, LURCHES FORWARD, OR ACCELERATES. I HAVE TO PRESS DOWN MY BRAKES REALLY HARD TO THE FLOOR TO STOP THE VEHICLE WHEN THIS HAPPENS. WHEN THIS FAILS, I IMMEDIATELY RELEASE THE BRAKE AND RE-APPLY VERY HARD TO THE FLOOR TO STOP THE CAR. IN THESE MOMENTS IT BECOMES SCARY AS I AM NEVER SURE IF THE CAR WILL COME TO A STOP BEFORE THE INTERSECTION. LAST WEEK, I WAS APPROACHING A BUSY INTERSECTION WHILE BRAKING AND I RAN OVER A UNEVEN POTHOLE COVER/FILLER AT ABOUT 5 TO 15 MPH WHICH CAUSED MY CAR TO ACCELERATE TO LIKE 20 OR 25 MPH! I HAD TO BRAKE VERY HARD IN ORDER TO STOP MY CAR AND SWERVE TO THE RIGHT TO AVOID HITTING THE CAR IN FRONT OF ME. THIS PROBLEM ONLY OCCURS WHEN MY RIGHT SIDE TIRES HIT THE UNEVEN SURFACE, MANHOLE COVER, POTHOLES, BUMPS, ETC. I HAVE NOT HAD AN INCIDENT WHERE IT HAPPENED WITH THE LEFT TIRES. TOYOTA SERVICE HAS SAID THERE IS NO PROBLEM WITH MY CAR'S BRAKES AND THEREFORE SAID THEY CAN'T FIX ANYTHING. THERE IS A PROBLEM WITH TOYOTA'S PRIUS BRAKING SYSTEM. *TR

THIS VEHICLE SHOULD BE PART OF THE LARGER TOYOTA RECALL ON BRAKES THAT WAS ANNOUNCED EARLIER THIS YEAR. AFTER A FEW THOUSAND MILES, I NOTICED THAT THE BRAKES GAVE WAY IF THE PRIUS HITS A BUMP OR POTHOLE. TOYOTA'S STATEMENT THAT "CUSTOMERS ARE PERCEIVING INCONSISTENT BRAKE FEEL DURING SLOW AND STEADY APPLICATION OF THE BRAKES ON ROUGH OR SLICK ROAD SURFACES" IS AN UNDERSTATEMENT. THE BRAKES DON'T ACTUALLY WORK WHEN YOU ARE DECELERATING AND HIT A BUMP, WHICH IS PROBLEMATIC WHEN YOU LIVE IN A CITY NOTORIOUS FOR POTHOLES. I REPORTED THIS ISSUE EARLY ON TO MY DEALER, AND HAVE SINCE FOLLOWED UP, EACH TIME BEING MET WITH THE SAME RESPONSE: THERE ARE NO REPORTS ON THIS ISSUE. FOR WHATEVER REASON, TOYOTA FEELS THAT ONLY CERTAIN VIN LOT NUMBERS MERIT THE RECALL, BUT I CAN ASSURE THEM THE PROBLEM IS MORE WIDESPREAD. MOST OWNERS I'VE TALKED TO HAVE TRIED TO ACCOMMODATE THE PROBLEM BY BEING AWARE OF BUMPS WHEN COMING TO A STOP, BUT AT SOME POINT SOMEONE WILL INJURE OR KILL SOMEONE ELSE AS A RESULT OF THIS BRAKING ISSUE. *TR

THIS INCIDENT HAS OCCURRED TWICE UNDER IDENTICAL CONDITIONS, IN THE SAME LOCATION. THE CAR DID NOT ENGAGE THE BRAKES UNTIL APPROXIMATELY ONE SECOND AFTER I DEPRESSED THE PEDAL. MAYBE THE COMPUTER'S ELECTRONIC STABILITY CONTROL IS INVOLVED IN THE PROBLEM, EVEN THOUGH THE CAR DID NOT INDICATE THAT ELECTRONIC STABILITY CONTROL WAS ENGAGED. BOTH TIMES I WAS DRIVING ON A SLIGHT DOWNHILL AT ~20 MPH. IMMEDIATELY AFTER I PASSED OVER SOME BUMPS, I DEPRESSED THE BRAKES, AND THERE WAS A SIGNIFICANT DELAY IN THE BRAKES BEING ENGAGED (1S). I THINK THE BUMPS IN THE ROAD ARE INVOLVED IN THIS ISSUE. OF NOTE, THIS CAR UNDERWENT AN UPDATE TO ITS SOFTWARE PROGRAM FOLLOWING A RECALL INVOLVING BRAKING PROBLEMS, AND THESE INCIDENTS OCCURRED AFTER THE UPDATE. *JB

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE BRAKE DELAYED TO ENGAGE WHILE DECELERATING. THE CONTACT WAS ABLE TO STEER THE STEERING WHEEL AWAY AND AVOID CRASHING INTO ANOTHER VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER SEVERAL TIMES FOR THE FAILURE AND A DIAGNOSTIC WAS PERFORMED, WHICH INDICATED THAT THE COMPUTER SYSTEM NEEDED TO BE RESET. THE COMPUTER SYSTEM WAS RESET BUT THE FAILURE WAS NOT CORRECTED. THE VEHICLE WAS ALSO TEST DRIVEN, BUT THE FAILURE DID NOT DUPLICATE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 2,000 AND THE CURRENT MILEAGE WAS 35,000.

WHILE BRAKING OVER AN UNEVEN SURFACE COMING UP TO A STOP LIGHT, THE CAR LURCHED FORWARD, CAUSING IT TO SEEMINGLY ACCELERATE INTO THE CROSSWALK. I WAS COASTING UP TO THE STOPLIGHT AND APPLIED THE BRAKES CLOSER TO THE LIGHT, AS THE CAR WAS TRAVELING OVER THE UNEVEN SURFACE. THE UNEVEN SURFACE WAS CAUSED BY RAISED METAL PLATES COVERING ROAD CONSTRUCTION. THE VEHICLE WAS TRAVELING ABOUT 5-10 MPH AND DECELERATING AT THE TIME OF THE INCIDENT. THIS HAS HAPPENED WITH REGULAR CONSISTENCY EVEN THOUGH THE CAR GOT THE SOFTWARE FIX WITHIN A FEW MONTHS OF PURCHASE IN 2010. IT MOSTLY HAPPENS DECELERATING OVER POTHOLES IN THE ROAD, WHEN GOING FROM COASTING (REGENERATIVE BREAKING) TO APPLYING THE BRAKES BY FOOT. *TR

WHILE BRAKING AT LOW SPEEDS -- SUCH AS WHILE APPROACHING A TRAFFIC LIGHT OR AN INTERSECTION -- PASSING OVER A POTHOLE OR UNEVEN ROAD SURFACE OFTEN CAUSES THE BRAKES TO DISENGAGE. THE SENSATION IS ONE IN WHICH MY FOOT IS IN THE SAME PLACE AS IT WAS WHEN I BEGAN BRAKING, BUT SUDDENLY THERE IS NO GIVE TO THE PEDAL, THE BRAKING HAS STOPPED -- BRAKING DOES NOT RETURN UNTIL I PUSH FURTHER DOWN ON THE PEDAL. MY FOOT IS NOT DISLODGED BY THE BUMP, AND THE BRAKING MECHANISM WILL NOT RE-ENGAGE UNLESS I PUSH THE PEDAL TO A NEW, DEEPER LOCATION. IT IS OBVIOUSLY DISCONCERTING AT INTERSECTIONS, AND SINCE MOVING TO A NEW LOCATION AND HAVING TO RE-LEARN WHERE ON MY ROUTES THIS PROBLEM WILL OCCUR, I DECIDED IT WAS TIME TO FILE A COMPLAINT. THE FRUSTRATION IS THAT THIS ISSUE WAS SUPPOSEDLY SOLVED A COUPLE YEARS AGO WITH A SOFTWARE FIX FROM TOYOTA, BUT THAT FIX SEEMS TO NOT HAVE WORKED. I FILED A COMPLAINT ABOUT THE PRIUS PROBLEM WITH SOME AGENCY (POSSIBLY NHTSA OR FTC) A FEW YEARS AGO WHEN THE OTHER, MORE NOTABLE, BRAKE-STICKING PROBLEM IN OTHER TOYOTAS WAS IN THE NEWS. THIS PARTICULAR ISSUE IS QUITE DIFFERENT. NOTE: THE DATE OF FIRST INCIDENCE IS APPROXIMATE, BUT THE PROBLEM PERSISTS. *TR

I WAS DRIVING CAR ABOUT 25 MILES P H AND SANDALEE THE ABS LIGHTS CAME UP AND ITS WAS READY HARD TO STOP THE CAR SOMEHOW BREAK WASN'T WORKING PROPERLY. *TR

WHEN I TRY TO BRAKE, OCCASIONALLY, THE CAR JUMPS FORWARD, INSTEAD OF STOPPING. IT MOVES LIKE 6 INCHES TO 12 INCHES. IT HAPPENS MORE OFTEN WHEN I TRY TO BRAKE AT A STOP SIGN, WHEN THE ROAD IS ROUGH, OR THERE IS A POTHOLE. IT GIVES A FEELING OF THAT CAR ACTUALLY ACCELERATED INSTEAD OF SLOWING, AND FEELS UNSAFE. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE ABS AND ANTI-SKID WARNING LAMPS ILLUMINATED WHILE THE CONTACT WAS DRIVING 40 MPH. THE BRAKE PEDAL WAS DEPRESSED HOWEVER, THE BRAKES FAILED. THE EMERGENCY BRAKE WAS USED TO STOP THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER AND DIAGNOSED AS BRAKE FAILURE. THE MASTER CYLINDER AND THE BRAKE BOOSTER ASSEMBLY WERE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 50,000. UPDATED 8/26/13 *CN THE CONSUMER STATED TOYOTA ADMITTED TO INSTALLING A FAULTY BRAKE PUMP. THE CONSUMER IS SEEKING REIMBURSEMENT. THE CONSUMER REFERENCED RECALL # 13V235000. UPDATED 09/10/13

THIS HAS HAPPENED ATLEAST 4 TIMES IN THE LAST YEAR, WHERE THE CAR HAS LOST COMPLETE BRAKING POWER AND AT THE TIME THIS HAPPENS, ALL THE LIGHTS ON THE DASHBOARD LIGHT UP FOR A FEW SECONDS AND ON SUBSEQUENT PUMPING OF THE BRAKE PEDAL, THE BRAKE POWER RETURNS TO NORMAL. ON ONE OCCASION I ALMOST ENDED UP IN THE MIDDLE OF AN INTERSECTION, THANKFULLY THERE WAS NO ONCOMING TRAFFIC AND WAS ABLE TO RECOVER WITHOUT GETTING CRASHED INTO. I SEE A LOT OF SIMILAR COMPLAINTS HERE AND ON TOYOTA'S OWN COMMUNITY PORTAL DESCRIBING THE EXACT SAME BEHAVIOR. IN ALL CASES, THE DEALERSHIP HAS ENDED UP REPLACING THE BRAKE BOOSTER ASSEMBLY. IN MY CASE THOUGH, THE DEALER CONFIRMED THAT MY CAR WAS ON THE RECALL LIST FOR THE BRAKE BOOSTER ASSEMBLY, BUT WHEN THEY RAN SOME DIAGNOSTICS TESTS ADVISED BY TOYOTA WHICH DID NOT REPORT ANY ISSUES AND THEREFORE REFUSED TO CHANGE THE BRAKE BOOSTER ASSEMBLY. I ALSO CONTACTED TOYOTA (CASE# [XXX]) ONLY TO BE TOLD A WISHY WASHY ANSWER. I WAS TOLD THAT TOYOTA CANNOT DO ANYTHING ABOUT IT SINCE IT HAS GIVEN GUIDELINES TO THE DEALERSHIP AND IF THE DEALERSHIP SAYS "NO" THEN SO DOES "TOYOTA". NOT TO MENTION HAVING SPENT HOURS ON THE PHONE WITH TOYOTA ONLY TO BE TOSSED SEVERAL TIMES BETWEEN DIFFERENT SUPPORTS REPS AND THE DEALERSHIP. ADDITIONALLY, I WAS TOLD BY THE DEALERSHIP TO KEEP DRIVING THE CAR AND SEE IF IT WAS TO HAPPEN MORE OFTEN. ONCE IT GETS TO A POINT WHERE I CAN FIND A PATTERN AND REPRODUCE THE ERROR WITH THE TOYOTA REP THAT'S THEN THEY WILL LOOK INTO THE ISSUE. FOR SOME REASON THEY FAIL TO UNDERSTAND THAT I AM NOT COMPLAINING ABOUT MY WIPER BLADES NOT WORKING BUT THE BRAKES, WHICH COULD PUT THE DIVER IN A LIFE THREATENING SITUATION.

ON 6-18-13 AT 9:45 AM, AT NJ TURN-PIKE SOUTH , MILESTONE 108.3, NEWARK, NJ. I ,OWNER OF THE TOYOTA PRIUS 201, DRIVING AT 45 MPH PUSHED THE BRAKE PEDAL TO THE FLOOR TO STOP BUT COULD NOT . I HIT THE BACK OF THE VEHICLE FRONT OF ME SUDDENLY STOPPED. MY 2010 PRIUS WAS TOTAL LOST IN THIS ACCIDENT. ACCORDING TO THE TOYOTA 6-4-13 RECALL ANNOUNCEMENT, MY 2010 PRIUS IN THE RECALL LIST IS EQUIPPED WITH A BRAKE PRESSURE ACCUMULATOR THAT MAY DEVELOP A FATIGUE CRACK ON AN INTERNAL PART DUE TO VIBRATION THAT CAUSED MY FAILURE TO STOP COMPLETELY IN THIS CAR REAR-END COLLISION ACCIDENT ON 6-18-13. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKES WOULD NOT RESPOND. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. THE TECHNICIAN STATED THAT NITROGEN GAS WAS LEAKING INTO THE BRAKE FLUID. THERE WAS A RECALL UNDER NHTSA CAMPAIGN NUMBER: 13V235000 (SERVICE BRAKES) THAT COULD HAVE BEEN RELATED TO THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THE VIN WAS NOT INCLUDED IN THE RECALL. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 46,000. *TR

AS WE WERE DRIVING THE CAR DOWN A HILL WE BEGAN TO FEEL A JERKING IN THE BRAKES. AS WE DROVE ONTO THE RAMP TO THE HIGHWAY, WARNING LIGHTS AND A BUZZER WENT OFF AND THE BRAKES FAILED. EVERY 15-30 SECONDS MY HUSBAND, WHO WAS DRIVING MY CAR AT THE TIME, SAID HE HAD A LITTLE BIT OF BRAKING FOR A COUPLE SECONDS, AND THEN HE DIDN'T HAVE ANY BRAKES AGAIN. *TR

SINCE PURCHASE OF VEHICLE WHEN STOPPING VEHICLE, AS APPROACHING A STOP SIGN OR STOPPED TRAFFIC, IF I HIT A SMALL BUMP IN ROAD, THE CAR JUMPS FORWARD. I HAVE NOT HIT ANOTHER CAR YET BUT FEEL THIS JUMP WHEN STEPPING ON BRAKES WHETHER IN DRY OR WET WEATHER COULD ONE DAY HIT CAR IN FRONT OF ME. THIS IS INTERMITTANT. DID MENTION TO DEALER WHEN CAR WAS FOR IT'S TIMELY SERVICES. DEALER SAYS THERE IS NO RECALLS. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THE BRAKES FAILED TO ENGAGE WHILE DRIVING 55 MPH ON AN EXIT RAMP. THE VEHICLE EVENTUALLY STOPPED BY DEPRESSING THE BRAKE PEDAL WITH FORCE. THE VEHICLE WAS DRIVEN TO THE DEALER FOR DIAGNOSTIC TESTING WHICH CONFIRMED THAT THE BRAKE POWER BOOSTER PUMP WAS LEAKING INTERNALLY. THE MANUFACTURER ADVISED THAT THE VEHICLE WAS NOT INCLUDED IN THE NHTSA RECALL CAMPAIGN NUMBER 13V235000 (SERVICE BRAKES). THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 46,000.

SLOWLY PASSED OVER A SPEED BUMP, WHICH CAUSED A BRIEF SENSATION OF ACCELERATION (COMMON IN THIS PRIUS). THEN BRAKING WAS SIGNIFICANTLY AFFECTED, WITH BRAKE TRAVEL QUITE LONG AND STOPPING POWER DIMINISHED. ALL BRAKES WARNING LIGHTS CAME ON AND STAYED ON. PROBLEM CONTINUED UNTIL I STOPPED THE CAR AND TURNED IT OFF. WHEN CAR TURNED ON, WARNING LIGHTS REMAINED BUT WENT OUT AFTER DEPRESSING BRAKE. TOOK TO DEALERSHIP. TOLD THAT BRAKE BOOSTER PUMP NEEDS TO BE REPLACED. VIN IS OUTSIDE THE RANGE GIVEN BY TOYOTA FOR RECALL PUBLISHED ON 6/5/13. HOWEVER, SYMPTOMS ARE IDENTICAL FOR THIS VEHICLE. I'M CONCERNED THAT TOYOTA MAY NOT BE INCLUDING ALL VEHICLES THAT ARE AFFECTED BY THIS PROBLEM IN ITS RECALL PLANS. *TR

FOR THE ENTIRE TIME THAT I'VE OWNED THE 2010 PRIUS, THE CAR LURCHES AHEAD VIRTUALLY EVERY TIME I RUN OVER A POTHOLE WITH THE BRAKES APPLIED (I.E., APPROACHING A STOP SIGN). WHEN I MENTIONED THIS AT ONE OF MY FIRST APPOINTMENTS, I WAS ASSURED THERE WAS NOTHING WRONG. NOW THE PROBLEM CONTINUES AND I'VE BEEN READING THAT MANY OTHER PEOPLE HAVE THE SAME ISSUE. *TR

I HAVE PREVIOUSLY (2010 OR 2011) FILED A DETAILED REPORT OF THE CONSISTENT ANOMALY THAT OCCURS WHILE BRAKING ON A ROUGH SURFACE OR UPON HITTING A POTHOLE, MANHOLE COVER, ETC. IN THIS SITUATION, THE FEEDBACK FROM THE VEHICLE SUGGESTS THAT THE BRAKES HAVE DISENGAGED. BASED UPON 2+ YEARS OF ADDITIONAL EXPERIENCE, I WOULD NOTE THAT: (1) THIS ANOMALY OCCURS CONSISTENTLY, AND IT HAS NOT DISAPPEARED OR ATTENUATED, (2) I BELIEVE THAT STOPPING DISTANCES ARE LONGER THAN WOULD BE EXPECTED WITHOUT THIS ANOMALY, (3) MY PRIUS WAS MANUFACTURED AFTER THE 2010 SOFTWARE FIX, AND (4) OTHER DRIVERS OF 2010 AND LATER PRIUS CARS HAVE REPORTED THE SAME PHENOMENON WHEN I ASKED ABOUT IT (SEE BELOW). MOST IMPORTANTLY, I WOULD NOTE THE FOLLOWING SOURCE OF EVIDENCE WHICH YOU MIGHT EASILY PURSUE FURTHER. I HAVE BEEN LIVING IN NEW YORK CITY (NYC) FOR MOST OF THE LAST TWO YEARS. THE NYC TAXI FLEET INCLUDES A SIZABLE NUMBER OF TOYOTA PRIUS CARS. EVERY TIME I TAKE A PRIUS TAXI, I ASK THE DRIVER IF HE HAS ENCOUNTERED A SIMILAR PROBLEM WHEN BRAKING ON ROUGH SURFACES. IN MORE THAN A DOZEN SUCH INSTANCES, DRIVERS HAVE CONSISTENTLY REPORTED THIS SAME PROBLEM. WHILE YOU MAY NOT WANT TO TRUST MY EVIDENCE ON THIS MATTER, IT WOULD BE VERY CHEAP FOR NHTSA TO SEND AN INVESTIGATOR TO SOME OF THE LARGE TAXI GARAGES IN NYC TO INTERVIEW DRIVERS WITH EXPERIENCE DRIVING PRIUS TAXI CABS. GIVEN THE LARGE NUMBER OF MILES LOGGED BY TAXI DRIVERS, THIS COULD BE AN IMPORTANT SOURCE OF INFORMATION FROM HIGHLY EXPERIENCED DRIVERS --- WHO MUST REGULARLY CONTEND WITH NYC'S MYRIAD POTHOLES. I WOULD FINALLY NOTE THAT --- OTHER THAN THIS ANOMALY --- I LOVE MY PRIUS. IT IS A GREAT CAR. I WOULD JUST LIKE FOR TOYOTA TO FIGURE OUR WHAT IS CAUSING THIS ANOMALY AND FIX IT. *TR

I'M A OWNER OF A 2010 TOYOTA PRIUS. I ALMOST CRASH INTO ANOTHER CAR, DUE TO THE BRAKE SYSTEM OF THIS VEHICLE. I HAD TO DRIVE OFF THE ROAD PAVEMENT TO AVOID THE CAR ACCIDENT. I HAD MULTIPLE TIMES NEAR MISS CAR ACCIDENTS BEFORE REPORTING THIS ISSUE. DUE TO THE VERY POOR BRAKING SYSTEM ON THIS VEHICLE. THE BRAKE RESPONSE IS VERY POOR. IN A QUICK REACTION FOR BRAKING, THIS CAR'S BRAKES WILL NOT STOP IN TIME TO AVOID ACCIDENT. AFTER A RECENT CLOSE CAR ACCIDENT 6/3/2013, I HAVE TO GIVE A LOT OF DISTANCE BETWEEN MY CAR AND OTHER CARS FOR BRAKING IN TIME TO AVOID A CAR ACCIDENT. AS A BUYER PURCHASING A NEW CAR, THE BRAKING SYSTEM IS A NUMBER ONE PRIORITY FOR SAFETY FOR A FAMILY OWNED CAR. I PURCHASE THIS CAR FOR A FUEL GAS SAVING CAR, BUT IT'S SCARY DRIVING THIS VEHICLE. DUE TO VERY POOR BRAKE SYSTEM IN THIS 2010 TOYOTA PRIUS. TOYOTA COMPANY NEEDS TO RECALL THE BRAKING SYSTEMS FOR ALL 2010 TOYOTA PRIUS. IT'S NEEDS TO BE CHECKED AND FIX FOR BETTER BRAKING QUALITY. I WANT TO SELL MY 2010 TOYOTA PRIUS, DUE TO THIS ISSUE OF BRAKING, BUT I CAN'T SELL THIS CAR DUE TO I STILL HAVE TO PAY OFF MY AUTO LOAN. MY FAMILY FEARS FOR MY SAFETY AND OTHER TOYOTA PRIUS OWNERS OUT THERE. PLEASE SOMEONE LOOK INTO THIS MATTER. I FEAR FOR MY FAMILY'S SAFETY DUE TO THIS PROBLEM.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, THE BRAKE AND TRACTION CONTROL WARNING LIGHTS ILLUMINATED. THE VEHICLE BECAME DIFFICULT TO STOP WHEN THE BRAKES WERE APPLIED. THE VEHICLE WAS TOWED TO THE DEALER FOR DIAGNOSIS AND THE CONTACT WAS INFORMED THAT THE BRAKE BOOSTER PUMP ASSEMBLY WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 39,001 AND THE CURRENT MILEAGE WAS UNKNOWN.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING 35 MPH, THE CONTACT APPLIED THE BRAKES THEN THE PEDAL WENT TO THE FLOOR AND THE VEHICLE FAILED TO STOP. THE CONTACT PUMPED THE PEDAL AND EVENTUALLY THE VEHICLE STOPPED. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE CONTACT WAS INFORMED THAT THE BRAKES NEEDED TO BE REPLACED. SEVERAL DAYS LATER THE FAILURE RECURRED. THE VEHICLE WAS RETURNED TO THE DEALER AND THE CONTACT WAS INFORMED THAT THE MASTER CYLINDER AND THE BRAKE BOOSTER WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER HAD NOT BEEN NOTIFIED OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 144,000.

THE VEHICLE HAS A NASTY HABIT OF LOSING BRAKE PRESSURE OVER BUMPS. THIS CAN BE DUPLICATED EASILY AND IS A KNOWN ISSUE THAT TOYOTA HAS YET TO RECTIFY. SIMPLY DRIVE OVER A BUMP SUCH AS A BREAK IN CONCRETE ON A BRIDGE, POTHOLE, ETC. AND HOLD ON TIGHT. THIS CAN RESULT IN A CRASH AND SERIOUS INJURY AS OCCUPANTS EXPERIENCE A SUDDEN LOSS OF BRAKING FORCE WHICH CAN INDUCE PANIC AND COLLISION. *TR

IN THE PAST (STARTING AT 2,800 MILES) AND REPORTED NUMEROUS TIMES TO THE DEALER (HUNTINGTON TOYOTA), TOYOTA CORPORATE AND THE NHTSA, WHENEVER THE CAR WENT OVER A ROUGH ROAD SERVICE WHILE BRAKING AT ABOUT 10 MILES AN HOUR THE REGENERATIVE BRAKING WOULD CUT OUT AND GIVE THE SENSATION OF THE CAR SURGING FORWARD REQUIRING MUCH GREATER BRAKING EFFORT TO BRING THE CAR TO A STOP. THE BRAKES WOULD RESET AFTER A FULL STOP AND THEY WOULD ACT NORMALLY UNTIL THE NEXT TIME BRAKING WAS DONE ON A ROUGH ROAD SURFACE. TOYOTA CLAIMED THAT THIS WAS NORMAL BEHAVIOR FOR THE PRIUS ABS SYSTEM, EVEN AFTER THE FIRMWARE UPGRADE WAS APPLIED. THIS TIME THE BRAKES DID NOT RESET AFTER A FULL STOP AND EVERY WARNING LIGHT ON THE DASHBOARD LIT UP. THERE WAS NO REGENERATIVE BRAKING AVAILABLE. THE CAR WAS BROUGHT TO THE DEALER WHO HAS HAD IT FOR MORE THAN A WEEK, AND IS REPLACING MAJOR BRAKE SYSTEM COMPONENTS UNDER MY EXTENDED WARRANTY. I WAS TOLD THAT WITHOUT THE WARRANTY THESE REPAIRS WOULD HAVE COST ME OVER $4500. THIS HAS BEEN AN ONGOING AND DANGEROUS SITUATION, WHICH MAY BE FINALLY RESOLVED AFTER ALL OF THE BRAKE COMPONENT REPLACEMENTS. AS AN ASIDE, THE BRAKE PADS SHOW SIGNIFICANT AND UNUSUAL WEAR BECAUSE THE REGENERATIVE BRAKING DID NOT WORK AS IT SHOULD. *TR

BRAKES FAILED WHILE DRIVING. PEDAL WENT TO THE FLOOR. VERY LITTLE BRAKING POWER LEFT. LUCKILY I DIDN'T HAVE TO STOP SUDDENLY AND WAS ABLE TO BRING THE CAR TO A STOP SLOWLY. HAD THE CAR TOWED TO TOYOTA DEALER WHERE THEY DIAGNOSED THE PROBLEM AS THE BRAKE BOOSTER / MASTER CYLINDER. THEY TOLD ME THERE WAS AIR IN THE BRAKE SYSTEM. I RECEIVED A QUOTE FOR ALMOST $2900 TO FIX THE BRAKES. I CALLED TOYOTA CORPORATE OFFICE AND ASKED FOR ASSISTANCE WITH THIS CATASTROPHIC BRAKE FAILURE BUT WAS REFUSED. SEARCHING ONLINE FOUND OTHERS WITH SAME FAILURE. IN PARTICULAR, THERE WAS A PERSON WITH 43K MILES WITH EXACT SAME ISSUE, AND TOYOTA REFUSED TO HELP HIM. THIS IS A VERY DANGEROUS FAILURE AND SHOULD BE A RECALL. PLEASE INVESTIGATE FULLY AND FEEL FREE TO CONTACT ME FOR ANY ASSISTANCE. I AM IN THE PROCESS OF REPLACING THE BRAKE BOOSTER BUT I WILL KEEP THE OLD ONE IN CASE YOU NEED IT FOR YOUR INVESTIGATION. I HAD SIMILAR ISSUE ON MY 2004 LEXUS RX330 AND THERE WAS EVENTUALLY A RECALL FOR IT. IT IS UNACCEPTABLE FOR A 3 YEAR OLD CAR TO HAVE THIS KIND OF A SAFETY FAILURE. MY WIFE AND KIDS COULD HAVE BEEN SERIOUSLY HURT OR KILLED. *TR

ON 01 MAY 2013, I WAS DRIVING MY TWO DAUGHTERS HOME FROM SCHOOL AND THE BRAKES ON MY 2010 TOYOTA PRIUS FAILED. THE BRAKE PEDAL BECAME VERY STIFF AND THE BRAKES DID NOT RESPOND. I BEGAN TO PANIC BECAUSE WE WERE TRAVELING DOWN A STEEP HILL. I CONTINUED TO PUMP THE BRAKES AND SUDDENLY, THE PEDAL GAVE WAY AND THE CAR CAME TO A SCREECHING HALT. I WAS LUCKILY WITHIN WALKING DISTANCE OF MY HOUSE. I HAD MY CAR TOWED TO THE DEALERSHIP AND THEY INFORMED ME THAT MY BRAKE BOOSTER AND MASTER CYLINDER NEEDED REPLACEMENT AT A COST OF $5500. I'M SHOCKED. MY CAR IS 3 YEARS OLD. AFTER RESEARCH, I DISCOVERED THIS IS A COMMON PROBLEM FOR THE 2010 PRIUS. WHAT I FIND MOST DISTURBING IS THIS IS CLEARLY A MANUFACTURER'S DEFECT, THAT IS AN EXTREMELY DANGEROUS SAFETY HAZARD. PRIOR TO OWNING MY PRIUS, I WAS A LOYAL TOYOTA BUYER. I HAVE HAD CONSISTENT ACCELERATION ISSUES WITH MY BRAKES, EVEN AFTER THE RECALL. IF TOYOTA DOES NOT ADDRESS THIS ISSUE, I DON'T INTEND TO PURCHASE ANOTHER TOYOTA PRODUCT. *TR

WHILE I WAS BRAKING TO STOP AT THE RED LIGHT, THE CAR ACCELERATED. I MOVED THE STEERING WHEEL TO HIT THE CURB TO PREVENT CROSSING THE RED LIGHT. IT HAPPENED TO ME COUPLE OF TIMES. THEN I REALIZE IT HAPPENS ONLY WHEN I AM DRIVING OVER UNEVEN SURFACE OR OVER BUMPS. IT IS REALLY SCARY. I ALMOST HIT A CAR SEATTLE DOWNTOWN GOING DOWN THE HIT BECAUSE MY CAR ACCELERATED INSTEAD OF STOPPING. I TOOK IT THE CAR DEALER BUT THEY SAID THERE IS NO PROBLEM. I AM AFRAID THAT I MIGHT GET IN A BIG ACCIDENT. *TR

THE BRAKE BOOSTER PUMP BEGAN RUNNING CONTINUOUSLY WHEN THE VEHICLE WAS ON. WARNING LIGHTS ON THE DASH INDICATED BRAKE FAILURE AND ANTI-LOCK SYSTEM FAILURE. AFTER I TOOK THE VEHICLE TO A TOYOTA DEALER, THEY DETERMINED THAT THE BRAKE MASTER CYLINDER/ANTI-LOCK ASSEMBLY HAD FAILED. THE REPAIR TOOK TWO WEEKS AND COST $3000. *TR

I WAS DRIVING TO WORK THIS MORNING AND A MAN STEPPED OFF THE CURB RIGHT IN FRONT OF ME (NOT IN A CROSSWALK). I HIT MY BRAKES, AND HIT A POTHOLE IN THE ROAD AT THE SAME TIME. THE CAR ACCELERATED AND FELT AS IF IT WAS SHUDDERING, IT WAS NOT BRAKING AT ALL EVEN THOUGH I MASHED THE PEDAL TO THE FLOOR. I WAS FORCED TO SWERVE TO MISS THE MAN, WHICH I THANKFULLY DID. AFTER THAT I GOT MOVING AGAIN I APPLIED THE BRAKES AND THEY WORKED FINE. WHEN I ARRIVED AT WORK I TRIED IT AGAIN BY FINDING SOME POTHOLES IN THE PARKING LOT. @ 15 MPH THE PROBLEM OCCURRED AGAIN ONLY WHEN I WAS HITTING THE POTHOLES WHILE APPLYING THE BRAKES. I WENT TO TOYOTA.COM AND FOUND THIS HAS BEEN AN ISSUE SINCE FEB 2010. I PURCHASED MY CAR IN NOV 2010; I THEN CALLED MY SERVICE DEALER AND TALKED TO THE SERVICE MANAGER WHO CLAIMED TO HAVE NEVER HEARD OF THAT PROBLEM EVEN THOUGH I TOLD HIM I FOUND THE INFO AT THE PRESSROOM.TOYOTA.COM WEBSITE. HE THEN PROCEEDED TO LET ME KNOW I SHOULD NOT BELIEVE EVERYTHING I READ IN THE INTERNET AND OFFERED TO LET ME BRING IT IN AND HE WILL LOOK AT IT. I AM LEAVING WORK EARLY TODAY TO HAVE IT LOOKED AT. *TR

IN THE MORNING I STARTED MY CAR AND THE ABS LIGHT AND WARNING LIGHTS CAME ON AND STARTED BEEPING. I REVERSED MY CAR SLIGHTLY TO CHECK THE BRAKES AND NOTICED MY BRAKES WERE NOT BEING RESPONSIVE. I PUT THE VEHICLE INTO PARK AND CALLED THE WONDRIES TOYOTA DEALERSHIP AND TOLD THEM MY BRAKES WERE NOT FUNCTIONING PROPERLY AND MY ABS WARNING LIGHT WAS ON. DESPITE MY HAVING INFORMED THEM OF MY BRAKE FAILURE, THEY TOLD ME TO BRING THE CAR INTO THE DEALERSHIP. I REVERSED OUT OF MY GARAGE, SHIFTED THE CAR INTO DRIVE, AND PROCEEDED DOWN THE HILL WITH CAUTION. I DID NOT PRESS ON THE ACCELERATOR. MY CAR BEGAN TO ACCELERATE DOWN THE HILL DUE TO GRAVITY AND REACHED A SPEED OF APPROXIMATELY 15 MPH, AT WHICH TIME I PUMPED THE BRAKE PEDAL BUT THE CAR WOULD NOT STOP OR SLOW DOWN, AND IT CONTINUED MOVING DOWN THE HILL. AT THE BOTTOM OF THE HILL, AFTER TRAVELING APPROXIMATELY 1/4 OF A MILE, I TURNED RIGHT INTO A SMALL STREET WITH A SLIGHT INCLINE IN ORDER TO STOP THE MOMENTUM. MY CAR SLOWED AND I PUT ON THE EMERGENCY BRAKE AND PUT THE CAR INTO PARK. I CALLED MY BROTHER FOR HELP. WHEN HE ARRIVED, I TURNED THE CAR ON TO SHOW HIM THE FLASHING ABS WARNING. IT FLASHED FOR ABOUT ANOTHER 15 SECONDS BEFORE SUDDENLY STOPPING. MY BRAKES THEN BEGAN FUNCTIONING AGAIN THOUGH THEY FELT SPONGY WHEN I PRESSED DOWN ON IT. I TURNED ON MY EMERGENCY LIGHTS AND DROVE SLOWLY TO THE DEALERSHIP. I PARKED THE CAR AND TURNED OFF THE ENGINE. WHEN A REPRESENTATIVE CAME BY, I TURNED ON THE CAR AND SHE PRESSED DOWN ON THE BRAKE TO FEEL THEM. THE ABS LIGHTS SUDDENLY CAME ON AGAIN AND SHE SAID THE BRAKE PRESSURE DID NOT FEEL RIGHT AND THERE WAS SOMETHING DEFINITELY WRONG WITH MY BRAKES. AFTER IT WAS ASSESSED I WAS INFORMED I NEEDED A NEW ABS ACTUATOR ASSEMBLY AND AN ACCUMULATOR PUMP FOR THE MASTER CYLINDER. TOTAL COST WAS ESTIMATED AS $4600. *TR

MULTIPLIE INCIDENTS: WE WILL BE DRIVING THE VEHICLE AND HIT A BUMP / POT HOLE AND BE BRAKING, BUT THE CAR WILL ACCELERATE. *TR

I WAS DRIVING MY 2010 PRIUS IN A CONGESTED AREA AND CARS IN FRONT OF ME STOPPED SUDDENLY. AS I BRAKED HARD, THE CAR SEEMED TO LURCH FORWARD FOR ABOUT ONE SECOND, MAYBE LONGER, AND THEN THE BRAKES KICKED IN. I NOTICED THAT THE ROAD WAS ROUGH. THE SURFACE WAS DRY. FORTUNATELY, I HAD ALLOWED AMPLE DISTANCE FROM THE CAR IN FRONT OF ME, AND THERE WAS NO COLLISION, BUT IT WAS VERY UNSETTLING. IN THE PREVIOUS MONTH, I HAD THREE OR FOUR LESS INTENSE SENSATIONS OF "LURCHING FORWARD," WHICH OCCURRED WHEN I STOPPED AT A PARTICULAR INTERSECTION WHEN I HAD JUST STARTED THE CAR, BUT THE ROAD WAS SMOOTH. *TR

I HAD BEEN HEARING A LOT OF GRINDING NOISES THAT JUST GOT WORSE. WHEN I WENT TO THE DEALER, THEY DISCOVERED THAT MY BRAKE PADS HAD FAILED/FROZEN. THEY REPLACED MY PADS AND MACHINED MY ROTORS. THEY COULD NOT EXPLAIN WHY A CAR I HAD FOR ONLY A LITTLE OVER A YEAR HAD THIS PROBLEM. THEY AT FIRST BLAMED MY DRIVING, AND THEN THE ROADS (I.E. TOO MANY GRAVEL ROADS). NOW, AT 68,300 MILES THOSE PADS HAVE NOW FAILED AGAIN. ONE IS COMPLETELY WORN DOWN AND THE ROTOR IS NOW RUSTED THROUGH. NO ONE CAN EXPLAIN WHY THIS IS HAPPENING. WHEN I DEMANDED AN ANSWER, THEY TOLD ME THAT A "BULLETIN" HAD GONE OUT TO THE DEALERS ONLY STATING THAT DUE TO THE PADS FAILING, THEY WERE "REDESIGNING" THEM. BUT, THEY WOULD ONLY REPLACE FOR FREE THOSE THAT FELL UNDER THE 36,000 MILE WARRANTY. I DON'T UNDERSTAND WHY, IN LESS THAN 69,000 MILES I HAVE HAD TO HAVE THIS REPAIR DONE NOT ONCE, BUT TWICE. THEY TELL ME NO OTHER OWNER HAS HAD THIS PROBLEM, BUT I FIND THAT HARD TO BELIEVE. CAN ANYONE TELL ME IF THERE ARE OTHER COMPLAINTS OF THIS TYPE, AND WHAT CAN BE DONE TO RECTIFY THIS PROBLEM. *TR

EXPERIENCED A COMPLETE BRAKE FAILURE WHILE DRIVING 2010 PRIUS. DEALER INDICATES BRAKE BOOSTER FAILING AND LEAKED NITROGEN INTO MASTER CYLINDER WHICH SHOULD THEN ALSO BE REPLACED. DEALER INSIST IT IS ONE ASSEMBLY AND ESTIMATES REPLACEMENT TO BE $5,166 ($1,638 FOR BOOSTER AND $2,466 FOR MASTER CYLINDER). DUE TO THE COMPLETE WARNINGLESS FAILURE OF BRAKES WHILE IN OPERATION IT WOULD SEEM TO A CRITICAL SAFETY HAZARD DUE TO THE DESIGN FLAW IN THE COMBINED BRAKE BOOSTER AND MASTER CYLINDER BRAKE ASSEMBLY CAUSING A BRAKE FAILURE IN OPERATION. *TR

WHEN BRAKING OVER ROUGH ROAD, BRAKES FAIL. *TR

VEHICLE HAS NO BRAKES AT ALL, WE TURNED THE IGNITION ON AND THE CAR START BEEPING, BRAKE LIGHT ITS ON, ABS LIGHT ON AND SLIP INDICATOR LIGHT IS ON. *TR

PROBLEM WITH 2010 PRIUS PERFORMING UNCONTROLLED HARD BRAKING WHILE DRIVING ON INTERSTATE AT APPROX 73~75 MPH. THIS HAPPEN ON TWO SEPARATE OCCASIONS, WITH THE FIRST BEING FEB 10, 2013. THE SECOND INCIDENT OCCURRED LATE AFTERNOON ON SAT. FEB 16, 2013. BOTH OCCURRENCES WERE IN LIGHT TRAFFIC, WHEREBY PREVENTING POTENTIAL SEVERE VEHICULAR REAR END COLLISIONS THAT COULD HAVE RESULTED IN SERIOUS BODILY INJURES AND GRAVE VEHICULAR DAMAGES. VEHICLE WAS CHECKED BY A TOYOTA DEALER AND PASSES ALL TROUBLESHOOTING TESTS, FEB 18, 2013. REQUESTED ADDITIONAL TESTS BE DONE ON FEB 19, 2013. TOYOTA DEALER COULD NOT RECREATE THE PROBLEM. NO FURTHER ACTIONS WERE TAKEN BY THE DEALER. *TR

THIS IS A RECURRING PROBLEM. ANYTIME I AM SLOWING DOWN FOR A RED LIGHT AND THERE IS A POTHOLE OR OTHER ROUGH SURFACE CONDITION, THE CAR LURCHES FORWARD AND JUMPS, SO TO SPEAK. GIVEN THE CONDITION OF THE ROADS IN CHICAGO, THIS IS A PRETTY REGULAR PROBLEM. I USUALLY HAVE TO PRESS THE BRAKE MUCH HARDER THAN NORMAL WHILE THIS IS OCCURRING BECAUSE OF CROSSWALKS AND LIGHTS. I THINK THIS IS A SERIOUS SAFETY ISSUE; HOWEVER, WHEN ASKING THE DEALER TO LOOK INTO THIS, THEY INDICATED THAT IT WAS THE ANTI-LOCK BRAKING SYSTEM KICKING IN, AND THAT IT WAS A PERFECTLY COMMON THING TO EXPERIENCE. *TR

ALL BRAKES FAILED WHILE I WAS GOING 69MPH ON I-75 SOUTH JUST NORTH OF THE UNION CENTRE BOULEVARD EXIT, APPROACHING I-275 AT THE BUTLER/HAMILTON COUNTY LINE ON SAT. DEC. 22.. ALL WARNING LIGHTS CAME ON AND THE WARNING "BEEPS". I WAS IN HEAVY TRAFFIC BUT WAS IN THE RIGHT LANE AND WAS ABLE TO EXIT ON THE UNION CENTRE EXIT RAMP AND ROLL TO A STOP. THIS HAPPENED THE DAY AFTER I HAD THE CAR AT PERFORMANCE TOYOTA IN FAIRFIELD, OH FOR THE 35,000 MILE CHECK/OIL CHANGE (ON DEC. 21) .THE CAR HAD TO BE TOWED TO PERFORMANCE TOYOTA ON DEC 22; THEY DETERMINED THE MASTER CYLINDER FAILED (LOST ITS VACUUM) CAUSING TOTAL BRAKE FAILURE. *TR

INCIDENT #1 BRAKE: ON JANUARY 17, 2013 AS I WAS ENTERING THE INTERSECTION ABOUT 20MPH, I APPLIED MY BRAKES, BUT THEY WENT STRAIGHT TO THE FLOOR AND WARNING LIGHT STARTED BLINKING. I PRESSED BRAKES VERY HARD AND CAR ALMOST STOP, THEN, ITS BRAKES GAVE UP. THERE IS SUDDEN SLIGHT "UNINTENDED ACCELERATION" AND I ALMOST HIT CAR FRONT OF ME. BUT, I AM ABLE TO MANAGE TO DROVE THE CAR INTO THE CENTER ISLAND. BRAKE WAS TOTALLY OUT, AND THE CAR STARTED DROVE BY ITSELF. I PANICKED AND PRESSED POWER BUTTON TO SHUT OFF THE ENGINE. CAR DROVE ABOUT 15 FEET AND STOPPED. AFTER THIS INCIDENT, I TOW MY CAR TO THE DEALER, THEY TOLD ME THAT LOST BRAKE IS DUE TO SHORT CIRCUIT MADE DOMINO EFFECT TO MULTIPLE COMPUTERS MALFUNCTION. THEY WILL REPLACE WHOLE COMPUTER SYSTEM, BUT SERVICE MAN WOULD NOT GUARANTEE IT WILL NEVER HAPPEN AGAIN. INCIDENT #2 POWER FAILED AND SHUT DOWN WHILE DRIVING AT HIGHWAY. ON DECEMBER, 2012 AND JANUARY 2013. I WAS DRIVING AT HIGHWAY AND TRYING TO MERGE INTO THE CENTER LINE, CAR STALLED AND PROMPTED "KEY DOES NOT DETECT" MESSAGE ON THE SCREEN. I ALMOST HIT FROM BEHIND BY ANOTHER CAR. WHILE THE CAR STILL HAS A SPEED ABOUT 40MPH, I MANAGED TO RESTART THE CAR BY DEPRESSED BRAKE AND PRESS POWER BOTTOM. IT IS TRUE THIS CAR LOSE BRAKE AND DOES SLIGHT "ACCELERATE". *TR

WHEN DRIVING ON AN UNEVEN OR WET SURFACE THE BRAKES SEEM TO LAG FOR A FEW SECONDS AND THE CAR HOPS FORWARD. *TR

IF YOU GO OVER A BUMP WHILE BRAKING - THE BRAKES FAIL, AND YOU HAVE TO TAKE YOUR FOOT OFF THE BRAKE AND RE-APPLY IN ORDER TO STOP. THIS HAS OCCURRED NUMEROUS TIMES - AND IS A SERIOUS FLAW ON THIS AUTOMOBILE. THIS CAR IS A FLEET VEHICLE FOR MY COMPANY AND I HAVE ASKED PEERS IF THIS OCCURS ON THEIR CARS - AND THEY HAVE CONFIRMED THE SAME EXPERIENCE WITH THEIR BRAKES. WITH ALL THE TOYOTA RECALLS - I AM UNCLEAR WHY THIS HAS NOT BEEN ADDRESSED...? *TR

I WAS IN THE RIGHT LANE TRAVELING WEST BOUND ON TENNESSEE STREET IN TALLAHASSEE, FL, AND AS I WAS GOING THROUGH THE LIGHT AT THE CORNER OF TENNESSEE AND MONROE STREET, THE TRAFFIC STOPPED JUST PAST THE INTERSECTION. AS I WAS ENTERING THE INTERSECTION, I APPLIED MY BRAKES BUT THEY WENT STRAIGHT TO THE FLOOR AND A WARNING LIGHT STARTED BLINKING. I HAD ONE OF TWO CHOICES; HIT THE CAR IN FRONT OF ME OR HIT THE CURB FOR THE SIDEWALK CLOSE TO WHERE A MAN WAS STANDING WITH HIS BICYCLE. LUCKILY I HAD JUST ENOUGH ROOM TO GO BETWEEN THE BACK-END OF THE CAR IN FRONT OF ME AND THE MAN ON THE SIDEWALK. FORTUNATELY NO ONE WAS INJURED IN MY ACCIDENT, I JUST SCARED THE MAN VERY BADLY, BUT THE REPAIRS TO MY CAR ARE PROBABLY GOING TO BE MORE THAN $4,000. *TR

OK, THIS TYPE OF INCIDENT (LOSS OF BRAKING AT LOW SPEEDS) HAS HAPPENED REPEATEDLY IN THIS VEHICLE, DESPITE A RECALL IN 2010 AND "SOFTWARE FIX". THE DATE LISTED IS APPROXIMATE. I FELT COMPELLED TO PROVIDE THIS INFORMATION AFTER HAVING THIS HAPPEN TWICE IN THE PAST WEEK, IN THE HOPES THAT SOME PERMANENT FIX CAN BE MADE AVAILABLE, AND TO WARN PROSPECTIVE BUYERS TO BE CAUTIOUS. IN ALL INCIDENTS, WHEN TRAVELING OVER BUMPS IN A ROAD WITH THE BRAKES ENGAGED, THERE IS A SUDDEN SLIGHT "ACCELERATION", BUT IN ACTUALITY, PROBABLY JUST THE MOMENTARY LOSS OF BRAKING. THIS HAPPENS WHEN GOING OVER: (1) MANHOLE COVERS (2) POTHOLES (3) SLIGHT DIPS IN THE ROAD (FROM SUBSIDING ROAD PATCHING AREAS). DOES NOT APPEAR TO BE WORSE IN WET CONDITIONS, AND HAS ONLY HAPPENED TO ME AT LOW SPEEDS (~5 -- ~ 20 MPH). NOTE THAT ORIGINAL CARPETED MATS WERE REPLACED WITH ONES THAT FIT A BIT BETTER, AND DO NOT CAUSE ANY ISSUES WITH THE ACCELERATION PEDAL. ONCE THE BUMP IS PASSED OVER, NORMAL BRAKING OCCURS. WHEN I FEEL THIS VEHICLE MOMENTARILY LOSE BRAKING, I QUICKLY LET OFF THE BRAKE FOR A SPLIT SECOND, AND RESUME BRAKING. I HAVE GOTTEN USED TO THIS DEFECT, BUT I SURE WOULD LIKE SOMEONE TO INVESTIGATE AND PROVIDE A QUALITY RECALL FIX. THIS BRAKING ISSUE HAS HAPPENED IN NORTH CAROLINA (WHERE THE VEHICLE WAS PURCHASED) AND IN MASSACHUSETTS. THANK YOU. *TR

WHEN I ENCOUNTER A BUMP WHILE APPLYING THE BRAKES IN MY 2010 TOYOTA PRIUS, THE BRAKES FULLY DISENGAGE MOMENTARILY. THIS CAUSES THE CAR TO JOLT FORWARD UNEXPECTEDLY. MY FOOT IS NOT COMING OFF THE BRAKE AT ALL WHEN THIS HAPPENS, SO I KNOW I AM NOT THE CAUSE OF IT. I RECEIVED A RECALL NOTICE BY MAIL IN FEBRUARY 2010 TO ADDRESS JUST THIS ISSUE. I TOOK THE CAR TO THE NEAREST TOYOTA DEALERSHIP TO HAVE THE RECALL WORK COMPLETED. IT WAS INTENDED TO FIX THE MALFUNCTION IN THE ANTI-LOCK BRAKE SYSTEM THAT CAUSED THE BRAKES TO DISENGAGE WHEN THE CAR HITS A BUMP. THE RECALL WORK WAS COMPLETED, BUT THE PROBLEM WAS NOT RESOLVED. THE BRAKES STILL DO THE EXACT SAME THING AND FULLY DISENGAGE WHEN I HIT A BUMP WHILE BRAKING. THIS IS UNQUESTIONABLY DANGEROUS AND A SERIOUS SAFETY HAZARD. *TR

TURNED ON CAR AND NOTICED ALOT OF THE DASHBOARD LIGHTS STAYED ON. AS I PRESSED THE BRAKE PEDAL IT FELT WEIRD AND ONCE I PUT THE CAR ON THE DRIVE GEAR I TOTALLY LOST BRAKE CONTROL, THE CAR KEPT MOVING AND I WAS NOT ABLE TO STOP. I HAD TO SHIFT TO "PARK" AND RISK THE TRANSMISSION BUT BETTER THAN RISKING MY LIFE... I CALLED A TOWING TRUCK. THE CAR IS AT THE TOYOTA DEALER AND I DON'T THINK THEY HAVE A CLUE OF WHAT'S WRONG WITH IT.... WE'LL KEEP YOU POSTED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS TRAVELING 25 MPH AND DROVER OVER A ROAD BUMP. THE CONTACT APPLIED THE BRAKES HOWEVER, THE VEHICLE WOULD NOT RESPOND. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 25,000. THE CURRENT MILEAGE WAS 75,000.

2010 TOYOTA PRIUS. CONSUMER STATES TWO BRAKE SYSTEM FAILURES *TGW THE CONSUMER STATED THE VEHICLE BEGAN MAKING AN UNUSUAL SOUND AND AFTER A FEW DAYS, NUMEROUS WARNING LIGHTS APPEARED ON THE DASHBOARD ANNOUNCING A FAILURE OF THE BRAKING SYSTEM. THE VEHICLE WAS TOWED TO THE DEALER. AN INSPECTION REVEALED THE MASTER CYLINDER, BOOSTER AND ECU NEEDED TO BE REPLACED. THE CONSUMER PAID $ 3,246.83 FOR THE REPAIRS. HOWEVER, NINE DAYS LATER, THE UNUSUAL BRAKE PEDAL SOUND RETURNED, BUT THE BRAKES WORKED AND NO WARNING LIGHTS APPEARED. THE NEXT DAY, THE BRAKE SYSTEM COMPLETELY FAILED WHILE HIS DAUGHTER WAS DRIVING THE VEHICLE. AGAIN, THE VEHICLE WAS TOWED TO THE DEALER, WHERE THE TECHNICIANS DETERMINED THE VEHICLE NEEDED A NEW BRAKE BOOSTER ASSEMBLY. THE CONSUMER WAS INFORMED HE WOULD ONLY BE RESPONSIBLE FOR THE LABOR COSTS OF $ 255.48. THE CONSUMER BELIEVED THE BOOSTER AND BRAKE BOOSTER WERE THE SAME PART, WHICH WAS SUPPOSED TO HAVE BEEN REPLACED SEVERAL DAYS PRIOR. JB

2010 PRIUS BRAKE FAILURE. I WAS ABLE TO SLOW DOWN THE CAR BY REPEATED PUMPING ON THE BRAKES. FORTUNATELY, MANAGED TO CRAWL TO A NEARBY TOYOTA DEALER BY USING THE PUMPING TECHNIQUE AND HAVE MY FOOT ON THE EMERGENCY FOOT BRAKE JUST IN CASE. TOYOTA SAID I NEED TO REPLACE THE MASTER CYLINDER WITH ACTUATOR. TOTAL COST PARTS/LABOR $4100. I AM UPSET BECAUSE MY FAMILY OR OTHERS COULD HAVE BEEN SERIOUSLY HURT IF I PANICKED AND NOT PUMPED ON THE BRAKE TO SLOW THE VEHICLE DOWN. THIS IS A SERIOUS HAZARD WHICH SHOULD BE KNOWN AS I HAVE SEEN OTHER SIMILAR COMPLAINS LODGE ONLINE. *TR

I APPLIED MY BRAKES APPROACHING A TRAFFIC LIGHT AND HIT A SMALL POT HOLE AND THE ENTIRE VEHICLE JERKED FORWARD EVEN THOUGH THE BRAKES WERE APPLIED AND NEVER TAKEN OFF THE PEDAL. I HAD TO THEN PRESS DOWN HARDER ON THE BRAKE PEDAL TO COME TO A COMPLETE STOP. I HAVE OBSERVED THIS TYPE OF BEHAVIOR WHEN THE ROAD CHANGES SURFACES AND IS LOWER THAN THE PREVIOUS SURFACE AND DIPS IN THE ROAD. THIS IS ALL OBSERVED WHILE ONLY BRAKING AT LOW SPEEDS LESS THAN 40 MPH. EVERY TIME THIS BEHAVIOR IS OBSERVED THERE IS A LOUD BANG, I AM NOT COMPLETELY SURE IF THIS IS FROM SWITCHING SURFACES OR HIT POT HOLES OR DIPS IN THE ROAD. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 40 MPH, THE CONTACT WAS ABLE TO ABNORMALLY DEPRESS THE BRAKE PEDAL INTO THE FLOORBOARD. THE ABS WARNING, TRACTION CONTROL WARNING AND THE EMERGENCY BRAKE WARNING LIGHTS ILLUMINATED ON THE INSTRUMENT PANEL. AFTER CONTINUALLY DEPRESSING THE BRAKE PEDAL, THE VEHICLE CAME TO A STOP. THE FAILURE RECURRED FOUR DIFFERENT TIMES. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN ADVISED THE CONTACT THAT THE BRAKE POWER BOOSTER WOULD HAVE TO BE REPLACED BUT DID NOT GUARANTEE THAT THE BOOSTER WAS THE ACTUAL CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 55,000.

TL* THE CONTACT WAS DRIVING A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING 40 MPH WHEN THE VEHICLE STOPPED IN THE STREET. PRIOR TO THE VEHICLE STOPPING, A BEEPING/ALARM SOUNDED, THE SEAT BELT LOCKED IN PLACE AND THE WARNING ON THE DASHBOARD FLASHED BRAKES.

WHEN APPROACHING AN INTERSECTION I HIT A POTHOLE & THE CAR SUDDENLY QUIT BRAKING AND REQUIRED ME TO DO EVASIVE DRIVING MANEUVERS TO ASSURE I DID NOT HIT THE VEHICLE IN FRONT OF ME OR THE LIGHT POLE AT THE INTERSECTION. SIMILAR "BRAKE RELEASE" HAS HAPPENED ON MULTIPLE OCCASIONS. WHEN BRINGING THIS MATTER TO THE DEALERSHIP ON MULTIPLE OCCASIONS I HAVE BEEN TOLD THAT THIS IS STANDARD OPERATION. WHEN PRESSED THEY SAY ITIS JUST THE WAY THE CAR IS DESIGNED. THUS, MY COMPLAINT TO YOU FROM THE LOBBY OF MY TOYOTA DEALERSHIP AS THEY REMOVE THE BRAKING COMMENTS, AGAIN, FROM MY APPOINTMENT RECORD HISTORY. PLEASE FORCE THE COMPANY TO RESOLVE THIS MATTER AS I WORRY ABOUT MY HEALTH & THAT OF MY FOUR CHILDREN WHO RIDE IN THE CAR WITH ME. IT SHOULD NOT BE ACCEPTABLE FOR A COMPANY TO KNOW THAT THEIR VEHICLE IS UNSAFE & TELL CUSTOMERS, "SORRY, WE HAVE A PROBLEM BUT WE DO NOT CARE... *TR

BRAKES DOES NOT WORK PROPERLY ON ROUGH SURFACE OR BUMPY ROAD I HAVE REPORTED COUPLE OF TIMES TO THE DEALER BUT DEALER TRY TO MISLEAD AND CONFUSED ME BY SAYING THAT IT IS ABS SYSTEM WHICH BECOMES ACTIVE ON BUMPY ROAD AND IT IS A NORMAL BRAKE OPERATION AND WE HAVE NO RECALL FOR THIS VEHICLE. PLEASE LET ME KNOW WHAT TO DO? THANKS. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN STARTING THE VEHICLE, HE NOTICED THAT THE BRAKES WOULD NOT OPERATE AS THEY SHOULD IF THE VEHICLE WAS WARM. WHEN DEPRESSING THE BRAKES, HE WOULD HAVE TO APPLY EXTREME FORCE IN ORDER TO GET THE BRAKE PEDAL TO ENGAGE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY ADVISED THE CONTACT THAT THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE CONTACT MENTIONED THAT THE FAILURE ONLY OCCURRED WHEN DRIVING DURING THE MORNING HOURS, AFTER THE VEHICLE HAD BEEN SITTING OVERNIGHT. THE MANUFACTURER HAD NOT BEEN CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 10,000. THE VIN WAS UNAVAILABLE.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING 20 MPH WHEN THE BRAKES WERE DEPRESSED BUT THE VEHICLE FAILED TO STOP. THE CONTACT THEN CRASHED INTO A SIGN. THERE WERE NO INJURIES. THE VEHICLE WAS TOWED TO THE DEALER BUT NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE AND CURRENT MILEAGES WERE 13,115.

WHILE THE CAR WAS PARKED IN A HILL WITH THE PARKING BRAKE IT SUDDENLY WENT BACKWARDS AND HIT THE WALL OF THE RESIDENCY ACROSS THE STREET LIKE 500 FEET DOWN. CAR WAS ALMOST COMPLETELY DAMAGE BACK, TRAIN SUSPENSION AND ALL DOORS OUT OF FRAME. REPAIR WILL TAKE 8 WEEKS AT A COST OF 14850.00. THERE WERE NO PASSENGERS IN THE CAR. *TR

EVEN AFTER ALL RECALL WORK WAS PERFORMED THERE IS AN ISSUE BRAKING WITH THE 2010 PRIUS. WHEN BRAKING OVER BUMPY SURFACES YOU OFTEN GET A FEELING THAT THE CAR IS ACCELERATING RATHER THAN BRAKING. I DO NOT THINK THE CAR ACTUALLY ACCELERATES - IT IS MORE OF AN ISSUE THAT THE BRAKES RELEASING WHEN I BROUGHT IT TO THE ATTENTION OF MY TOYOTA DEALER THEY DO NOT THINK IT IS A PROBLEM. WHEN IT HAPPENS IN BUMPER TO BUMPER TRAFFIC IT CAN REALLY SCARE YOU! I WORRY LETTING MY KIDS DRIVE THE CAR. AND NO - IT IS THE ABS IS KICKING IN. *KB

THE PRIUS SEEMS TO ACCELERATE WHILE STEPPING ON THE BRAKE AT SLOW SPEEDS--THE CAR FEELS LIKE IT JERKS FORWARD. THIS USUALLY HAPPENS WHILE I AM ON A ROAD WITH POTHOLES. *KB

WHEN I STARTED TO DRIVE HOME, THE CAR WAS LURCHING WHILE BRAKING. IT WAS AN UNCONTROLLED ACCELERATION. ONCE I GOT ON THE FREEWAY, MY BRAKE LIGHT, ABS LIGHT AND SLIPPAGE LIGHTS ALL CAME ON AT ONCE (ALONG WITH BEEPING NOISE THAT DOES NOT GO AWAY). I PULLED OVER TO THE SIDE OF ROAD AND NOTICED THAT MY BRAKES HAD DEGRADED BY ABOUT 75 PERCENT.....WHILE I DID HAVE SOME BRAKES IT WOULD HAVE NOT BEEN ENOUGH FOR AN EMERGENCY STOP OR NORMAL TRAFFIC BRAKING. *KB

I WAS DRIVING ON I-680 NORTH TODAY AND SUDDENLY THE "BRAKE", "ABS" AND "SLIP INDICATOR" TURNED ON AND STARTED BEEPING. AT THAT TIME I DID NOT REALIZE WHAT HAPPENED, BUT WHEN I TRIED TO BRAKE THE PEDAL WAS REALLY HARD TO PRESS AND I WAS NOT ABLE TO SLOW DOWN. I FINALLY WAS ABLE TO SLOW DOWN BY GOING ON A RAMP AND THEN REALLY PRESSING DOWN ON THE BRAKE WHERE THE CAR JERKED AND SLOWED DOWN. AGAIN THE BRAKES WERE NOT WORKING. I WAS FINALLY ABLE TO GET THE CAR TO STOP. WHEN I TURN THE CAR ON AGAIN, THE SAME LIGHTS SWITCH ON AND THE CAR IS BEEPING. *TR

WHILE DRIVING ON INTERSTATE, THE BRAKE AND VEHICLE STABILITY ASSIST LIGHTS SUDDENTLY WENT ON AND A BEEPING ALARM SOUNDED. THE BRAKES WERE NOT VERY EFFECTIVE, AND IT WAS VERY DIFFICULT TO SLOW DOWN AND STOP THE CAR WHEN WE PULLED OVER. WE HAD THE CAR TOWED TO THE DEALERSHIP, WHERE THEY INFORMED US THAT THE ABS PUMP AND THE ENTIRE BRAKING SYSTEM NEEDED TO BE REPLACED...ON OUR ONE YEAR OLD CAR! PARTS ALONE TOTALED OVER $4000 DOLLARS, WITHOUT LABOR. TOYOTA WAS UNWILLING TO REPLACE, AS THE CAR WAS OUT OF WARRANTY FOR MILEAGE. CLEARLY A DEFECTIVE SYSTEM IN OUR CAR, BUT THEY WERE NOT WILLING TO STAND BEHIND THEIR PRODUCT TO COVER. ANGRY CUSTOMER, ESPECIALLY GIVEN THE FACT THAT TOYOTA STATES THAT THEY WANT TO RESTORE CUSTOMER FAITH IN THEIR PRODUCT. WE WERE LUCKY THAT INJURY DID NOT RESULT FROM THE FAILURE OF THE PARTS NEEDED TO STOP THE CAR.

WHEN I AM DRIVING AND HIT A POTHOLE, THE CAR JOLTS FORWARD. IT'S A PRETTY SCARY FEELING TO BE OUT OF CONTROL WHEN THAT HAPPENS. I DON'T DRIVE OFTEN, SO I CAN ONLY IMAGINE HOW MANY MORE TIMES THIS COULD HAPPEN. I DO LIKE MY CAR AND IS ONLY A YEAR OLD, BUT THIS IS QUITE CONCERNING. I AM EXTRA CAREFUL, BUT WHAT IF I HIT SOMEONE IN THE STREET OR THE CAR IN FRONT OF ME. I HAVE SEEN A FEW COMPLAINTS ABOUT THIS SAME EXACT REASON. PLEASE SOMETHING HAS TO BE DONE ABOUT IT BEFORE SOMEONE GETS HURT. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE VEHICLE WAS SERVICED UNDER NHTSA CAMPAIGN ID NUMBER: 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE CONTACT NOTICED THAT AFTER THE RECALL REPAIRS, THERE WAS AN ABNORMAL INCREASE IN STOPPING DISTANCE WHEN BRAKING OVER UNEVEN PAVEMENT. THE CONTACT STATED THERE HAVE BEEN SEVERAL OCCASION WHEN THE VEHICLE FLOATED INTO AN INTERSECTION BECAUSE THE FAILURE PREVENTED THE VEHICLE FROM STOPPING. THE VEHICLE WAS TAKEN TO THE DEALER FOUR TIMES WHERE THE CONTACT WAS TOLD THERE WERE NO FAILURES WITH THE VEHICLE BECAUSE THE BRAKING SYSTEM WAS OPERATING AS DESIGNED. THE FAILURE MILEAGE WAS UNAVAILABLE.

MY DRIVING RECORD WAS CLEAN UNTIL THIS 2010 PRIUS. IN ONE YEAR I HAVE HAD TWO ACCIDENTS AND SEVERAL INCIDENTS, ALL OF WHICH I AM NOW CONVINCED DUE TO BRAKE FAILURE. THE FIRST ACCIDENT TOOK PLACE END OF DECEMBER 2010. I WAS GOING ONLY ABOUT 10 MPH. I HIT THE BRAKES REPEATEDLY TO TRY TO GET THE CAR TO STOP. AT THE TIME I THOUGHT THE CAR DID NOT STOP BECAUSE OF ICE, BUT NOW AFTER THIS 2ND ACCIDENT AND RESEARCHING OTHER PRIUS REPORTS, I AM CONVINCED THIS FIRST ACCIDENT WAS ALSO BECAUSE THE BRAKES FAILED TO WORK. SINCE I DID NOT SUSPECT THIS AT THE TIME, I DID NOT REPORT IT OR HAVE THE BRAKES CHECKED WHEN THE CAR WAS REPAIRED. THE 2ND ACCIDENT WAS LAST NIGHT, DEC 8TH, 2011. I WAS TRAVELING BETWEEN 25-30 MPH. THE BRAKES CLEARLY FAILED TO WORK, AND I HIT A CAR STOPPED AT THE TRAFFIC LIGHT IN FRONT OF ME. I HAD PLENTY OF DISTANCE TO STOP. THE CAR DID NOT SLOW DOWN, IF ANYTHING, IT MAY HAVE SPEEDED UP, BUT I CANNOT DEFINITELY SAY THIS, AS I WAS TOO FREAKED OUT LOOKING AT THE CAR I WAS GOING TO HIT TO CHECK MY SPEED. THE ROAD WAS NOT ICY. THE IMPACT DEMOLISHED THE FRONT END OF THE PRIUS. MY AIR BAG ALSO DID NOT INFLATE. I HAVE WHIPLASH FROM THIS SECOND ACCIDENT. FORTUNATELY NO ONE ELSE WAS INJURED. I NOW REALIZE I HAD SEVERAL OTHER BRAKE 'SLIPPAGE' PROBLEMS LAST WINTER THAT DID NOT RESULT IN ACCIDENTS AND I DID NOT IDENTIFY THEN AS BRAKE PROBLEMS. I THOUGHT IT WAS MY SNOW TIRES, EVEN THOUGH THEY WERE BRAND NEW. I TOOK THE CAR BACK TO THE TIRE DEALER LAST MONTH WHO SAID THEY HAD NO OTHER COMPLAINTS ABOUT THAT BRAND OF TIRE, BUT I SO CONCERNED I HAD THEM REPLACE THE TIRES ANYWAY WITH NEW ONES OF A DIFFERENT BRAND. I HAVE OPENED A CASE WITH TOYOTA AFTER I STARTED TO RESEARCH 2010 PRIUS AND FOUND A RECALL ON THIS MODEL AND YEAR FROM BEFORE I LEASED THIS CAR. TOYOTA SAYS THERE IS NOT A RECALL ON MY VIN#. I WANT TOYOTA TO TAKE RESPONSIBILITY FOR THIS ACCIDENT AND TAKE BACK THE CAR. *TR

WHILE DRIVING, WHEN VEHICLE IS COASTING (DECELERATING) IN ECO MODE/ENGINE OFF AND BRAKES ARE APPLIED UNDER SPECIFIC CONDITIONS SUCH AS PASSING OVER A MAN-HOLE COVER OR POTHOLE THE FOLLOWING OCCURS: CAR DECELERATES, AS WHEEL/TIRE HITS AN ANOMALY IN THE ROAD SURFACE THE BRAKES MOMENTARILY FAIL AND THE CAR SURGES FORWARD AS THE ENGINE STARTS. THE SENSATION IS A LOSS OF BRAKING FORCE, PLUS MOMENTARY SURGE IN THE FORWARD DIRECTION. REACTION TO THIS SITUATION IS MILD PANIC AND OVERBRAKING, (LITERALLY SLAMMING ON THE BRAKE PEDAL). THIS PROBLEM CAN BE RECREATED FAITHFULLY AT ONE ROAD CLOSE TO A STOPSIGN/INTERSECTION. THIS PROBLEM HAS OCCURRED FOR MONTHS. RECENTLY (11/30/11) WHEN FOLLOWING A CAR ON THIS SPECIFIC ROAD THE CAR STOPPED ABRUPTLY DUE TO AN ANIMAL JARTING INTO THE ROAD. I APPLIED THE BRAKES, BRAKE ANOMALY OCCURRED AND FELT I COULD NOT STOP IN TIME. EVASIVE DRIVING MEASURES FORCED ME INTO THE ON-COMING TRAFFIC LANE TO AVOID A COLLISION. TOYOTA UNWILLING TO ADDRESS THIS ISSUE AT THE DEALER OR CORPORATE. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 20 MPH THE CONTACT DEPRESSED THE BRAKE PEDAL AND IT FELL TO THE FLOOR BOARD. THE CONTACT WAS ABLE TO AVOID CRASHING INTO SEVERAL VEHICLES HE TURNED ONTO A SIDEWALK AND HIT A STREET LAMP, WHICH THEN CRASHED ON TOP OF THE VEHICLE, CAUSING EXTENSIVE DAMAGE. A POLICE REPORT WAS FILED. THE POLICE OFFICER INSPECTED THE VEHICLE AND CONFIRMED THE BRAKES HAD FAILED. THE VEHICLE WAS TOWED TO AN AUTO BODY SHOP. THE VEHICLE WAS INCLUDED PREVIOUSLY IN THE RECALL UNDER NHTSA CAMPAIGN ID NUMBER: 10V039000 (SERVICE BRAKES, AIR:ANTI-LOCK:CONTROL UNIT/MODULE) AND HAD THE RECALL REPAIRS PERFORMED. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 8,190 ....UPDATED 12/03/12 *BF UPDATED 01/11/12

I'M AN OWNER OF A 2010 PRIUS. TEN DAYS OR SO AFTER I PURCHASED THE CAR(IN JAN 2010), I EXPERIENCED A LOSS IN BRAKING WHICH RESULTED IN DAMAGE TO THE BUMPER. NUMEROUS!!!! ALMOST DAILY!!!! TIMES SINCE, EVEN AFTER THE RECALL FIX (DONE ON MY VEHICLE ON 3/10/10), I HAVE EXPERIENCED, NOT ONLY A LOSS OF BRAKING (USUALLY WHILE GOING OVER SOME LITTLE BUMP) BUT THE CAR ACTUALLY LURCHING FORWARD. QUITE DRAMATIC AND SCARY, ESPECIALLY IF THERE IS A STOP SIGN, INTERSECTION, A CAR OR A PERSON IN FRONT OF YOU. LAST THURS (11/10/11), THE ROAD SURFACE WAS WET, AND I BRAKED AND HAD NO, NONE , NADA BRAKES AND I REAR ENDED THE PERSON IN FRONT OF ME. I PAID FOR HER DAMAGE OUT OF MY OWN POCKET. I HAVE NOT FIXED THE DAMAGE DONE TO MY CAR. BRAND NEW ALL SEASON TIRES ON THE CAR, BY THE WAY. TODAY (11/14/11), AGAIN THE ROAD SURFACE WAS WET, I WAS BEHIND A CAR IN THE RIGHT LANE WHEN A CAR INAPPROPRIATELY BEGAN MERGING FROM A RAMP ON THE RIGHT, CAUSING THE CAR IN FRONT OF ME TO SUDDENLY SLOW DOWN. I BRAKED, AND AGAIN, NOTHING!!! I QUICKLY LOOKED IN MY SIDE VIEW MIRROR AND SAW I HAD CLEARANCE TO GO IN THE LEFT LANE, AND MANAGED TO AVOID CONTACT. 10 DAYS AFTER I PURCHASED THE 2010 PRIUS, I SAID I WANTED TO RETURN IT AND I SENT IN ALL THIS DOCUMENTATION CERTIFIED MAIL, BUT TOYOTA REJECTED EVERYTHING. THERE IS A DEFECT IN THIS CAR AND IT IS UNSAFE. *TR

WHEN I WAS PULLING INTO A PARKING SPOT, THE BRAKES FAILED AND THE VEHICLE ACCELERATED ON ITS OWN CAUSING ME TO RUN OVER THE CEMENT PARKING STOP AND CRASH INTO A CEMENT WALL. THE VEHICLE THEN BACK UP FROM THE CONCUSSION AND ACCELERATED ONCE AGAIN CAUSING ME TO CRASH TWICE. I FINALLY CAME TO MY SENSES AND SHUT THE VEHICLE OFF. I HAD BEEN NOTICING THE BRAKES FEELING STRANGE PRIOR TO THIS INCIDENT. THIS CAUSED $6,400 IN DAMAGE. TOYOTA WAS ALERTED, HAD THE VEHICLE INSPECTED AND CLAIM IT REVEALED NO EVIDENCE OF ANY SORT OF MALFUNCTION OR DEFECT. IN MY HEART, I KNOW THAT IS NOT TRUE. THIS WAS A VERY FRIGHTENING EXPERIENCE AND I DREAD THIS HAPPENING AGAIN. *TR

I JUST GOT AN EMAIL FROM MYCARSTATS.COM WHICH AFTER READING THROUGH COMPLAINTS ONE HIT ME AND I THOUGHT "THAT'S EXACTLY WHAT HAPPENED TO US". AT THE TIME, A COUPLE OF MONTHS AGO, WITH TOYOTA'S KNOWN PROBLEMS, I TOLD MY WIFE TO REMEMBER THIS AND LET ME KNOW IF IT EVER HAPPENS AGAIN (WHICH IT HAS NOT). THE PROBLEM OCCURRED WHEN WE WERE TRAVELING AT A LOW SPEED AND I HIT AN SPEED BUMP THE VEHICLE SURGED LIKE I HAD BUMPED THE GAS PEDAL ONLY I HAD MY FOOT ON THE BRAKE.

I GENTLY DRIVE MY 2010 TOYOTA PRIUS IN ECO MODE TO MAXIMIZE FUEL ECONOMY. EVERY WEEKDAY, SINCE JANUARY 2011, I SLOW ON A CERTAIN ROAD TO MAKE A RIGHT TURN. THE ROAD HAS A MANHOLE COVER RECESSED ABOUT 1 INCH INTO THE ROAD ALONG THE PATH OF MY PASSENGER SIDE TIRES. EVERY TIME I DRIVE OVER THIS MANHOLE COVER THE PRIUS COMPLETELY LOSES ABILITY TO BRAKE FOR ABOUT 1/2 SECOND, THEN BRAKING IS REESTABLISHED. THERE ARE OTHER SMALL BUMPS I DRIVE OVER AT OTHER PLACES WHICH HAVE THE SAME RESULTS TO THE PRIUS BRAKING SYSTEM. YESTERDAY (26 OCT 2011) SOMETHING DIFFERENT BUT POSSIBLY ASSOCIATED HAPPENED WHILE DRIVING OVER A BUMP. THIS TIME I WAS ACCELERATING AFTER HAVING MADE A RIGHT TURN FROM A COMPLETE STOP. WHILE STILL ACCELERATING AFTER THE TURN I SIGNALED LEFT AND PROCEEDED TO MERGE INTO THE LEFT HAND LANE. AS THE PRIUS RIGHT FRONT TIRE DROVE OVER THE REFLECTIVE LANE MARKER IMBEDDED IN THE ROAD SURFACE (THE MARKER STICKS OUT ABOUT 1/2 INCH FROM ROAD SURFACE) THE PRIUS WENT OUT OF CONTROL. THE CAR SUDDENLY AND SEVERELY PULLED HARD TO THE LEFT AND RAPIDLY SLOWED, I STRUGGLED AGAINST THE CARS ACTIONS TO AVOID HITTING THE RAISED CENTER MEDIAN. MY FIRST THOUGH WAS THAT I MUST HAVE HAD A COMPLETE AND INSTANTANEOUS BLOW OUT ON THE FRONT LEFT TIRE. MY REACTION WAS TO IMMEDIATELY REMOVE MY FOOT FROM THE ACCELERATOR. THEN AS I WAS FURTHER ASSESSING MY OPTIONS AND THE SURROUNDING TRAFFIC THE PRIUS REGAINED CONTROL AND I WAS ABLE TO CONTINUE DRIVING DOWN THE ROAD AS IF NOTHING HAD EVER HAPPENED. AS THE PRIUS REINSTATED CONTROL I HEARD A BEEP COME FROM THE DASHBOARD, HOWEVER I WAS NOT QUICK ENOUGH TO NOTICE IF ANY WARNING LIGHTS HAD ENGAGED DURING THE INCIDENT. WHEN I LOOKED AT THE DISPLAYS EVERYTHING APPEARED NORMAL. I ALSO CHECK THE CAR EXTERNALLY AND EVERYTHING APPEARED NORMAL. ALL INCIDENTS ARE ON HIGH QUALITY ROAD SURFACES WITH DRY PAVEMENT. DEALER INDICATES NO RECALLS. *TR

I DEPRESSED THE BRAKE PEDAL AND, INSTEAD OF SLOWING DOWN, MY CAR SURGED FORWARD FOR ABOUT 20 FEET BEFORE BRAKES ENGAGED AND THE CAR STOPPED --- JUST BEFORE THE INTERSECTION (RED LIGHT). I BARELY AVOIDED HITTING A TRUCK IN FRONT OF ME (I WAS ABLE TO DRIVE AROUND). ROAD SURFACE WAS DRY,WITHOUT ANY POTHOLES,BUMPS,ETC. I TOOK THE CAR TO THE TOYOTA SERVICE CENTER. AFTER CHECKING MY CAR THEY INFORMED ME THAT THE COMPUTER DID NOT DETECT ANY MALFUNCTIONS, THE TEST DRIVE WAS ALSO UNEVENTFUL,SO THAT NOTHING COULD BE DONE TO RESOLVE THE PROBLEM. THIS CAR'S BRAKING IS OBVIOUSLY UNPREDICTABLE AND IT IS ,WITHOUT A DOUBT, NOT SAFE TO DRIVE. *TR

CAR ABS LIGHT COMES ON, AND AT THE SAME TIME VEHICLE LOSES BRAKE ASSIST OR BRAKE ASSIST BECOMES UNEVEN. CAR HAS HAD THREE BRAKE LIGHT FAILURES - 1 WITH PREVIOUS OWNER AND 2 WITH CURRENT OWNER. FIRST FAILURE WAS REPAIRED BY RESETTING THE COMPUTER, WE THINK. WITH CURRENT OWNER, DEALER HAS REPLACED THE ANTILOCK SENSOR TWO TIMES, AND WITH THE SECOND SENSOR REPLACEMENT TOYOTA NOW HAS PRONOUNCED THE VEHICLE AS SAFE. SINCE THE BRAKES FAILED AFTER THE FIRST SENSOR REPLACEMENT, WE HAVE LITTLE CONFIDENCE THAT THE PROBLEM WAS SOLVED WITH THE SECOND SENSOR REPLACEMENT. WE ARE CONCERNED ABOUT VEHICLE SAFETY, ESPECIALLY SINCE THE CAR IS FREQUENTLY DRIVEN IN HEAVY WASHINGTON BELTWAY TRAFFIC. TYPICALLY CAR RUNS FOR SOME TIME AND THEN FAILS, SO WE DO NOT KNOW IF AND WHEN IT WILL HAPPEN AGAIN. DEALER AND TOYOTA HAVE BEEN UNSUPPORTIVE TO OUR CONCERNS. *TR

2010 TOYOTA PRIUS. CONSUMER STATES WHEN ONE OF THE FRONT TIRES TRAVELS OVER UNEVEN PAYMENT SPECIFICALLY AN INDENTATION IN THE ROAD THE BRAKING ACTION FAILS MOMENTARILY *TGW THE CONSUMER STATED THE VEHICLE LUNGED FORWARD A FEW FEET, BEFORE THE BRAKES ENGAGED AGAIN. THE DEALER INFORMED THE CONSUMER THE ISSUE HAD TO DO WITH THE ABS/TRAC SYSTEM. *JB

MY ISSUE IS SIMILAR TO OTHERS THAT HAVE COMPLAINED. WHEN TRAVELING A LOW SPEEDS AND I HIT AN UNEXPECTED BUMP THE VEHICLE SURGES FORWARD. THIS IS VERY DANGEROUS AND ONE THAT I WOULD HOPE TOYOTA TAKE NOTICE AND ADDRESS IMMEDIATELY. *TR

I FIRST REPORTED THIS TO TOYOTA PRIOR TO THE INITIAL 2010 RECALL, THE CAR WAS LESS THAN 1 MONTH OLD AND I HAVE REPORTED IT ON NUMEROUS OCCASIONS VIA THE TOYOTA WEBSITE. ON THE FEW OCCASIONS I LENT THE CAR TO FRIENDS THEY HAVE HAD THE SAME EXPERIENCE. DESCRIPTION: WHEN TRAVELING AT RELATIVELY SLOW SPEEDS AND AN UNEXPECTED BUMP COMES UP AND THE BRAKES ARE ENGAGED EARLY, ONCE GOING OVER THE BUMP THE CAR LOSSES BRAKE POWER FOR A FEW SECONDS AND JOLTS FORWARD. IT IS VERY DISCONCERTING B/C IN THOSE SPLIT SECONDS IF ONE IS NOT PREPARED THE CAR HURLS FORWARD AND COULD IF ALL ODDS ARE AGAINST ME, THE CAR COULD KILL SOMEONE IF THEY ARE WALKING IN FRONT OF THE CAR. I REPORTED IT TO MY DEALER, MY DEALER'S INSPECTOR WENT OUT ON TEST DRIVE WITH ME, WE WERE ABLE TO RECREATE THE INCIDENT WHEN HE WAS DRIVING AS THERE ARE A FEW SPOTS IN MY NEIGHBORHOOD THAT IT HAPPENS EVERY TIME. HE PUT THE COMPUTER ON THE CAR BUT IT DID NOT READ THERE WAS A PROBLEM. HE CALLED THE NATIONAL TECHNICAL OFFICE, WHO EVENTUALLY CAME OUT, I LEFT THE CAR AT THE DEALERSHIP. THEY RECREATED THE PROBLEM AND ACCORDING TO THE LOCAL TECHNICIAN THEY PUT A CAMERA IN THE WHEEL TO FILM THE SITUATION. I WAS LATER TOLD BY MY LOCAL TECHNICIAN THAT IT WAS DETERMINED THAT THERE WAS NOT A PROBLEM WITH THE CAR AND THAT THE SITUATION IS NORMAL WHERE THE TIRE CATCHES AN UNEVEN SURFACE AND GOES INTO OVERDRIVE. I HAVE HAD DREAMS THAT I WOULD KILL SOMEONE IN THIS CAR. NOONE IS ALLOWED TO USE THIS CAR FOR THE SAME REASON. I FEAR FOR MY LIFE AND THE LIFE OF ANYONE WALKING IN FRONT OF ME ON A STREET I DO NOT KNOW. IT HAPPENS ALMOST EVERY 2 WEEKS. IT IS SCARY! PLEASE HELP! THIS IS THE FIRST NEW CAR I BOUGHT IN 25 YEARS AND I AM UNABLE TO GET RID OF IT B/C I HAD TO PAY SO MUCH FOR IT. WHEN I INQUIRED WHAT MY OPTIONS WERE, TOYOTA SAID NONE, THAT THERE IS NO PROBLEM WITH THE CAR. *TR

I PURCHASED MY 2010 PRIUS IN AUGUST 2010. FOR THE PAST YEAR, I HAVE HAD PROBLEMS WITH THE BRAKE SYSTEM WHEN ATTEMPTING TO BRAKE AT LOW SPEEDS. WHEN BRAKING AT LOW SPEEDS, SUCH AS STOPPING AT A RED LIGHT OR STOP SIGN, IF THE CAR HITS A BUMP OR A POTHOLE, IT STOPS BRAKING AND INSTEAD ACCELERATES FORWARD A BIT. IT IS EXTREMELY FRIGHTENING AND I FIND IT EXCEPTIONALLY DANGEROUS. I HAVE COME EXTREMELY CLOSE TO HITTING THE VEHICLES IN FRONT OF ME ON SEVERAL OCCASIONS. I NOW HAVE TO TRY TO CONSCIENTIOUSLY ADJUST AND DRIVE VERY, VERY SLOWLY WHEN BRAKING ON UNEVEN ROAD SURFACES SINCE I HAVE COME TO ANTICIPATE THIS PROBLEM. HOWEVER, MANY TIMES THERE IS NO WAY TO AVOID THE CAR'S SURGE OF POWER. I BELIEVE THIS IS A HIGHLY DANGEROUS SITUATION WITH MY VEHICLE. A SIMPLE INTERNET SEARCH WILL DEMONSTRATE THAT THIS PROBLEM EXISTS AND WAS NOT RESOLVED WITH THE RECALL IN MARCH 2010. I PURCHASED MY PRIUS, NEW, FIVE MONTHS AFTER THE PROBLEM WAS ALLEGEDLY FIXED AND I HAVE HAD THIS PROBLEM SINCE DAY ONE. THE BRAKES HAVE BEEN EXAMINED ON MY VEHICLE BY A TOYOTA DEALER AND THEY APPEAR TO BE FINE. I HIGHLY BELIEVE THAT A RECALL IS APPROPRIATE TO FIX THIS DANGEROUS BRAKING ISSUE. *TR

WHEN I PRESSED THE BRAKES WHILE APPROACHING A STOP I HIT A BUMP IN THE ROAD (LARGE POT HOLE). THE PRESSURE ON THE BRAKE RELEASED FOR APPROXIMATELY 1 SECOND BEFORE THE PRESSURE ON THE BRAKE PAD RE-ENGAGED. THIS SAME SCENARIO CAN HAPPEN ANY WHERE FROM 0 TO 2 TIMES PER WEEK. IN THE WINTER WHEN THE ROAD SURFACE IS NOT CLEAR IT IS APPARANT THAT WHEN THE BRAKE "DISENGAGES" THE ANTI-LOCK DOESN'T ENGAGE BECAUSE THE CAR SLIDES. I HAVE SLIDE THROUGH A RED LIGHT, ONTO A BUSY STREET. FORTUNATELY THERE HAVE NOT BEEN CARS IN THE VACINITY. I HAVE TAKEN THE CAR TO THE DEALERSHIP 3 TIMES FOR THIS PROBLEM WITH NO SOLUTION OR RECOMMENDATION.

2010 TOYOTA PRIUS, WITH 29000 MILES. PULLING INTO A PARKING LOT AT A VERY SLOW SPEED, APPLIED BRAKES TO STOP CAR, BUT IT DID NOT STOP IT, IT STARTED JERKING FORWARD, UNTIL IT STOPPED WHEN IT STRUCK A FENCE, INJURIES OCCURED AS A RESULT, SEAT BELT DID NOT OLD BACK DRIVER, AND DRIVER WIPPED FORWARD AND BACK STRIKING STEERING WHEEL. VEHICLE WAS TOWED TO TOYOTTA DEALER. STILL WATING FOR TOYOTA CORP TO ADVISE OF ERROR THAT OCCURED, DATA FROM CMPUTER HAS BEEN DOWNLOADED BY A PRIVATE FIRM AND DELIVERED TO TOYOTA. 8/9/11 ACCIDENT OCCURED ON 7/25/11 AT 14:30. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE WAS INCLUDED IN THE RECALL UNDER NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE) AND HAD THE REPAIRS PERFORMED. THE CONTACT STATED THAT AFTER THE REPAIRS WERE PERFORMED, WHILE DRIVING APPROXIMATELY 15 MPH OVER A UNEVEN ROAD SURFACE, THE BRAKE PEDAL WAS DEPRESSED AND THE VEHICLE SUDDENLY ACCELERATED FOR A FEW MOMENTS. THE CONTACT ALSO STATED THAT THE FAILURE ONLY OCCURRED WHEN DRIVING OVER AN UNEVEN ROAD SURFACE. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSTICS, WHERE THE TECHNICIANS WERE UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 100. THE VIN WAS NOT AVAILABLE. HAD THE RECALL DONE BUT IT DID NOT FIX THE PROBLEM. TOYOTA HAS BEEN UNRESPONSIVE AND THE DEALERS SAY THERE'S NOTHING THEY CAN DO. UPDATED 11/16/2011 *LN *TR

EVER SINCE I PURCHASED MY 2010 PRIUS IN NOVEMBER, 2009 THE BRAKES HAVE BEEN A PROBLEM. WHEN BRAKING WHILE DRIVING OVER A BUMP OR POTHOLE THE CAR LOOSES BRAKING ABILITY AND THERE IS A SURGE OF POWER. THE DEALERSHIP CLAIMS THERE IS NO PROBLEM AND THE RECALL WORK HAS NOT MADE A NOTICEABLE DIFFERENCE. *TT

BRAKES FAILED. 2010 TOYOTA PRIUS. 160,000 MILES ON VEHICLE. WHEN I STARTED THE CAR, I HAD NO BRAKES. WHEN I PUT THE CAR IN GEAR, I THEN HAD BRAKES. I HAD BRAKES WHEN I PULLED UP TO A STOP SIGN. AS I WAITED FOR TRAFFIC I THEN HAD NO BRAKES. WHEN I BEGAN TO MOVE I HAD BRAKES, BUT THEN AS I GAINED SPEED, THE BRAKES WENT OUT. I MANAGED TO STOP WITH THE EMERGENCY BRAKE. CHECKED THE BRAKE FLUID: COMPLETELY FULL. DEALER SAID THE MASTER CYLINDER WENT BAD. ORGINAL BRAKES ON VEHICLE; NOT EVEN HALF USED. HIGHWAY MILES ON VEHICLE. VERY HOT DAY. I BELIEVE IT IS ELECTRICAL, DEALER SAYS MECHANICAL. HAD THERE BEEN AN ACCIDENT, THIS INCIDENT WOULD BE LOOKED INTO. AS IT IS, NO DEALER WILL LOOK INTO A CAR THAT IS OUT OF WARRENTY. I COMPLAINED FOR 5 MONTHS ABOUT THE BRAKES WHEN I FIRST BOUGHT THE CAR NEW. DEALER TOLD ME THAT THERE IS NOTHING WRONG WITH THE BRAKES. EVEN AFTER THE RECALLS, THERE STILL IS PROBLEMS WITH THE BRAKES. NOW I BELIEVE THERE IS A PROBLEM WITH THE MASTER CYLINDER, -THE ELECTRIC COMPONENT PART OF IT- BUT TOYOTA WILL ONLY LOOK INTO IT WHEN THERE IS A SERIOUS ACCIDENT.

HAVING PROBLEMS WITH THE BRAKING ON MY 2010 TOYOTA PRIUS. AT SLOW TO MODERATE SPEEDS WHILE I AM BRAKING AND GO OVER A POTHOLE THE CAR SEEMS TO STOP BRAKING AND KEEPS GOING. I THEN HAVE TO DEPRESS THE BRAKE HARDER TO MAKE THE CAR STOP. I HAVEN'T HAD ANY COLLISIONS BECAUSE OF THIS ISSUE BECAUSE I HAVE NOT BEEN FOLLOWING CLOSELY BEHIND A CAR. BUT I BELIEVE IF I WAS, I WOULD HAVE DEFINITELY REAR-ENDED ANOTHER VEHICLE. *TR

I AM EXPERIENCING THE SAME PROBLEM AS MANY OTHER 2010 PRIUS OWNERS. THE BRAKES FAIL BRIEFLY WHEN DRIVING OVER LARGE POTHOLES LOCATED ON A GRADE. I HAVE DISCUSSED THE PROBLEM WITH A TOYOTA DEALERSHIP AND WAS TOLD THAT THEY ARE AWARE OF THE PROBLEM BUT UNTIL A RECALL/SOLUTION IS ISSUED THERE IS NOTHING THAT THEY CAN DO. THEY TOLD ME TO BRAKE HARDER WHEN DRIVING OVER POTHOLES TO COMPENSATE FOR THE PROBLEM; THE BRAKES, HOWEVER, DO NOT FAIL WITH EVERY POTHOLE. IT SEEMS LIKE THE POTHOLES HAVE TO BE A CERTAIN SIZE, YET FROM THE DRIVER'S SEAT, IT'S EXTREMELY DIFFICULT TO JUDGE THE SIZE OF THE POTHOLE AND THUS IF THE CAR WILL LOSE BRAKING POWER. SO, SLAMMING ON THE BRAKES FOR EVERY POTHOLE IS JUST AS DANGEROUS AS NOT SINCE STOPPING TOO QUICKLY CAN CAUSE A REAR-END ACCIDENT. I LIVE IN A CITY OVERWHELMED WITH HILLS AND POTHOLES SO THIS PROBLEM HAPPENS NEARLY EVERY TIME I DRIVE THE CAR. IT HAS GOTTEN TO THE POINT WHERE I AM FEARFUL TO DRIVE MY CAR SINCE I HAVE HAD SEVERAL CLOSE CALLS AND KNOW THAT UNLESS THIS PROBLEM IS FIXED, IT WILL EVENTUALLY CAUSE AN ACCIDENT. BRIEFLY LOSING BRAKING POWER MAY SEEM INSIGNIFICANT BUT UNTIL YOU HAVE ACTUALLY DRIVEN THE CAR AND EXPERIENCED THE LACK OF CONTROL THE ONLY COMPARISON THAT I CAN MAKE IS DRIVING ON ICE. YOU FEEL UTTERLY HELPLESS FOR THE TIME THAT THE CAR IS OUT OF YOUR CONTROL, EVEN IF IT'S ONLY A FEW SECONDS, DURING WHICH TIME YOU ARE LEGALLY AND MORALLY ACCOUNTABLE FOR WHAT YOUR CAR DOES OR HITS. THERE ARE PLENTY OF OTHER ROAD HAZARDS AND SAFETY CONCERNS, WHETHER OR NOT MY CAR IS GOING TO STOP WHEN I APPLY THE BRAKES SHOULD NOT BE ONE OF THEM. I IMPLORE YOU, PLEASE INVESTIGATE THIS PROBLEM AND REQUIRE THAT TOYOTA TAKE RESPONSIBILITY FOR FIXING IT AND ENSURING THE SAFETY OF PRIUS OWNERS, PEDESTRIANS AND OTHER DRIVERS. THANK YOU.

I WAS MAKING A SHARP RIGHT TURN TO PULL INTO A PARKING SPACE, SLOWING TO A STOP. THE CAR SUDDENLY AND UNEXPECTEDLY ACCELERATED FORWARD OUT OF MY CONTROL. I APPLIED THE BRAKES AS HARD AS I COULD, WITH NO RESPONSE. AS THE CAR WAS RACING INTO A TREE, I SHUT OFF THE ENGINE BY PUSHING THE POWER BUTTON TO OFF. THE CAR KNOCKED DOWN A TREE AND CAME TO A STOP ON TOP OF IT.

I PURCHASED A 2010 PRIUS. WITHIN A 100 MILES, THE BRAKE PEDAL RANDOMLY LOCKED UP, THE BRAKES GRABBED AND BROUGHT MY CAR TO AN ABRUPT HALT. THE BRAKE PEDAL REMAINED LOCKED FOR ABOUT 3-5 SECONDS. THE CAR WOULD NOT MOVE FORWARD OR BACKWARD UNTIL AFTER THE BRAKE PEDAL UNLOCKED ITSELF. INITIALLY THIS HAPPENED IN REVERSE MODE SEVERAL TIMES, THEN IT WAS HAPPENING ONCE A WEEK AND IN FORWARD MODE AS WELL AS REVERSE. I TOOK IT IN FOR REPAIRS, MOST RECENTLY TOYOTA HAD MY CAR FOR A MONTH. NOTE THAT DURING THIS MONTH LONG INVESTIGATION NOTHING WAS DONE TO MY CAR, IT JUST SAT THERE. UPON MY LEAVING THE DEALERSHIP THE BRAKE PEDAL ACTUALLY LOCK UP! THE FIELD REPRESENTATIVE CONFIRMED THE PEDAL TO BE LOCKED AND WOULD NOT RELEASE FOR 30 SECONDS OR LONGER. HE TOOK MEASUREMENTS AND THE ENGINEER TOOK PHOTOS OF THE BRAKE PEDAL AS IT WAS UP IN THE AIR AND NOT DEPRESSED AS A NORMAL PEDAL WOULD BE. HE INSTRUCTED THE SERVICE MANAGER TO SEND ME HOME IN A LOANER CAR AND NOT THE PRIUS BECAUSE OF THE BRAKE PEDAL. I WAS SO RELIEVED THAT SOMEONE FINALLY SAW THE BRAKE PEDAL LOCKED UP AND NOT RELEASE. AFTER AN ADDITIONAL WEEK, THE DEALER CONTACTED ME AND SAID THAT TOYOTA DETERMINED THAT THIS CONDITION IS NORMAL AND THAT THE VEHICLE IS OPERATING AS DESIGNED! WHEN I REQUESTED THAT THE PHOTOS AND MEASUREMENTS OF THE LOCKED UP BRAKE PEDAL BE INCLUDED IN MY SERVICE REPORT, THE FIELD REPRESENTATIVE REFUSED TO FURNISH THAT DATA. INSTEAD, HE DENIED HE WITNESSED THE BRAKE PEDAL LOCK UP. THERE WERE NO CODES, NO WARNING LIGHTS OR WARNING SOUNDS, A SERIOUS SAFETY DEFECT IN ADDITION TO THE BRAKES LOCKING UP. THE DEALER INFORMED ME THAT TOYOTA IS AWARE THAT 1% OF THE PRIUS CARS HAVE THIS PROBLEM AND ARE WORKING ON A FIX! I BELIEVE THAT THE DESIGN AND/OR MANUFACTURING DEFECT HAVE RESULTED IN AN INHERENTLY DANGEROUS PRODUCT AND TOYOTA IS TRYING TO COVER IT UP. PLEASE CHECK INTO THIS, I BELIEVE MANY PEOPLE ARE AT RISK. 1% OF A MILLION CARS IS A LOT OF DRIVERS, PASSENGERS AND OTHERS SHARING THE ROAD. *TR

SUDDEN LOSS OF BRAKING WHILE SLOWING DOWN WHILE GOING OVER A BUMP. APPARENTLY THE REGENERATIVE BRAKING FAILS, AND THE CAR RELIES ON ONLY FRICTION BRAKING WHEN GOING OVER A BUMP. THIS GIVES THE FEELING OF BRAKE FAILURE AND UNINTENDED ACCELERATION, AND THE ONLY WAY TO PREVENT AN ACCIDENT IS TO PUSH HARD ON THE BRAKES. THIS HAPPENS CONSISTENTLY, AND HAS SINCE THE CAR WAS NEW. THE TOYOTA ABS ECU FLASH WAS PERFORMED, AND MADE LITTLE OR NO DIFFERENCE.THIS IS VERY DISCONCERTING TO SAY THE LEAST, AND WILL LEAD TO ACCIDENTS. TOYOTA CLAIMS THAT THIS IS THE "NORMAL" OPERATION OF THE ABS SYSTEM - IN REALITY IT HAS NOTHING TO DO WITH THE LOSS OF TRACTION.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE CONTACT WAS DRIVING APPROXIMATELY 10 MPH, THE BRAKE PEDAL WAS ENGAGED AND THE VEHICLE BEGAN TO LURCH FORWARD UNEXPECTEDLY. THE FAILURE RECURRED WHENEVER DRIVING IN RAINY WEATHER CONDITIONS OR BUMPY AND ICY ROAD SURFACES. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER AND REPAIRED UNDER NHTSA CAMPAIGN ID NUMBER: 10V039000 (SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE). THE RECALL REMEDY FAILED TO CORRECT THE PROBLEM AND THE FAILURE PERSISTED AFTER THE REPAIR. THE FAILURE MILEAGE WAS APPROXIMATELY 1,000. THE VIN WAS UNAVAILABLE.

I TRAVEL QUITE A BIT THESE DAYS AND ON MY WAY HOME FROM COACHELLA MUSIC FESTIVAL, MY BRAKES GAVE OUT. I MEAN TO SAY, PUSHING THE PEDAL ALL THE WAY DOWN, NO RESISTANCE, NO SLOWING, A COMPLETELY LIMP PEDAL....UNTIL I REPEATEDLY STOMPED ON IT AND THE CAR LOCKED AND SKIDDED TO A STOP, FEET AWAY FROM THE CAR IN FRONT OF ME. THE BRAKES RETURNED INTERMITTENTLY, SO I TOOK THE RIGHT HAND LANE AT 40MPH AND TESTED THE BRAKES REGULARLY UNTIL I GOT TO MY DEALERSHIP. SCARIEST THING IVE EVER EXPERIENCED. IVE HAD THE CAR SINCE AUGUST 09' AND CURRENTLY HAVE 43K MILES ON IT. I KNOW THATS A LOT, AND ITS UNFORTUNATELY OUTSIDE OF MY WARRANTY NOW, BUT I WANTED TO LOG IT HERE, AS SOON AS I COULD. IT STARTED ONE DAY BEFORE THE FREEWAY INCIDENT, WHENEVER I WOULD DEPRESS THE PEDAL, A LOUD HIGH PITCHED SQUEAK WOULD COME OUT. I DIDNT THINK MUCH OF IT OUTSIDE OF "BETTER GET THAT LOOKED AT" BUT DIDNT NOTICE ANY BRAKE FAILURE. THE NEXT MORNING, I TURNED ON THE CAR AND EVERY DASHBOARD LIGHT CAME ON AND A FAST CONSISTANT BEEPING WENT ON FOR ABOUT 5 MINUTES, DURING WHICH TIME THE BRAKE PEDAL HAD ZERO RESISTANCE. I SAT THERE WITH A SERIOUS WTF LOOK ON MY FACE, WHEN OUT OF NOWHERE, THE DASH LIGHTS WENT AWAY, AS DID THE BEEPING, AND THE CAR DROVE AS NORMAL WITH FULL REGULAR BRAKE PRESSURE (BESIDES THE SQUEAK). I RECEIVED A CALL BACK FROM THE DEALERSHIP. THEY SAY IT'S GOING TO BE $3K FOR A MASTER CYLINDER REPLACEMENT AND THAT TOYOTA CORPORATE WOULDN'T AID IN THE COST, DESPITE MY HYBRID WARRANTY STILL COVERING THE HYBRID ECU (THE MASTER CYLINDER UNIT INCLUDES THE ECU). [XXX] (MY DEALERSHIP SERVICE MANAGER) SAID HERSELF THAT IT WAS NOT MY FAULT AND THAT THE PART IS NOT REPAIRABLE, "IT EITHER WORKS, OR IT DOES NOT. IT MUST BE REPLACED". THIS COULD HAVE BEEN CATASTROPHIC, HAD I BEEN ANY CLOSER TO THE CAR IN FRONT OF ME. THE FAILURE OF ONE PART (WHICH FAILED THROUGH NO FAULT OF THE CUSTOMER) RENDERING THE BRAKES NEARLY USELESS IS TOO SCARY NOT TO REPORT HERE. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

2010 TOYOTA PRIUS. CONSUMER STATES PROBLEM WITH THE ABS SYSTEM *TGW THE CONSUMER STATED THE FIRST TIME HE WENT TO THE DEALER FOR THE ABS PROBLEM, THEY WERE UNABLE TO FIND A DEFECT. ONE MONTH LATER, THE CONSUMER RETURNED TO THE DEALER AND THEY REPROGRAMMED THE ABS AND THE BRAKES WORKED FINE FOR ABOUT ONE WEEK. SOON, THE BRAKES BEGAN SLIPPING AGAIN AND ULTIMATELY, THE CONSUMER CRASHED INTO ANOTHER VEHICLE. THE CONSUMER STATED IT SEEMED THE BRAKES WOULD FAIL WHEN HE APPLIED THE BRAKE, RELEASED HIS FOOT AND THEN BRAKED AGAIN. *JB

2010 PRIUS. BRAKE FADE DURING HARD BRAKING ON ROUGH SURFACE. THE BRAKES SUDDENLY FADE THEN GRAB HARD. *TR

BACKED 2010 PRIUS UP AND STARTED TO MAKE U-TURN IN DRIVEWAY. WHEN PULLED FORWARD TURNING APPLIED BRAKES AND WELL THERE WERE NONE. TRAVELED ABOUT 15 FEET AND HIT A BRICK WALL. AFTER SOME DELAY THE ENGINE NOW HAD SOME CONTROL AS THE BRAKES ALSO DID. WAITING FOR TOWING INSTRUCTIONS TO GET THE CAR TO GARAGE. MAXIMUM SPEED WAS MAYBE 5MPH. *TR

DRIVING ON A RAIN COVERED ROAD AND HIT A ROUGH SPOT IN THE ROAD. BRAKES DID NOT ENGAGE AT ALL FOR ABOUT 1 SECOND. WAS ABLE TO STOP AFTER THAT AND JUST AVOIDED REAR ENDING A CAR AT A STOP SIGN.

2010 TOYOTA PRIUS--INCONSISTANT BRAKING AND VARYING BRAKE PEDAL PRESSURE REQUIREMENTS. WHEN BRAKING, BRAKE PEDAL TRAVEL DISTANCE VARIES. AT TIMES NO BRAKE ACTION AFTER PEDAL HAS BEEN PARTIALLY DEPRESSED REQUIRING MORE BRAKE PRESSURE TO RE-ENGAGE BRAKES. SOMETIMES OCCURS WHEN GAS ENGINESWITCHES TO ELECTRIC OR VICE VERSA, OTHER TIMES INCONSISTENT BRAKE ACTION OCCURS WITH EITHER POWER SOURCE. FRANKLY YOU NEVER KNOW HOW THE BRAKES WILL PERFORM. TAKEN TO DEALER-I WAS TOLD NO PROBLEM FOUND. THEY WOULD NOT KEEP THE CAR FOR DAYS TO CONTINUE TESTS. THIS IS MY FOURTH PRIUS AND THIS VEHICLE HAS MORE PROBLEMS AND CONCERNS THAN ALL THE OTHERS COMBINED. *TR

I DRIVE A 2010 TOYOTA PRIUS. IN THE LAST WEEK I HAVE NOTICED ON SEVERAL OCCASIONS THAT WHEN BRAKING WHEN COMING UP TO A TRAFFIC LIGHT, ALL OF A SUDDEN THE PRESSURE ON THE PEDAL DECREASES AND THE BREAKING POWER FADES. THEN IN PANIC I START PUMPING THE PEDAL WHICH AFTER A SPLIT SECOND GETS THE BRAKES TO KICK IN AGAIN. LUCKILY THE CAR HAS SO FAR THEN COME TO A HALT BEFORE I HIT THE CAR IN FRONT OF ME. MY TOYOTA DEALER HAS DISMISSED MY CLAIM SAYING THAT THEY CHECKED THE CAR AND THE COMPUTER SHOWS NO ERROR CODE. THEY TOLD ME THAT EVERYTHING IS FINE BASICALLY DISMISSING MY CLAIMS OF A NEAR CRASH. THEY SAY THERE IS NOTHING THEY CAN DO AND IF THE COMPUTER SHOWS NO ERROR EVERYTHING MUST BE FINE. THE FIRST OCCURRENCE OF THIS WAS ON THE SAME DAY WHEN I HAD TO BRAKE VERY HARD TO AVOID A CRASH. ON THAT OCCASION THE BRAKES WORKED FINE BUT DRIVING HOME THE SAME NIGHT I HAD THE FIRST OCCURRENCE OF THE ABOVE DESCRIBED SITUATION RESULTING IN A NEAR CRASH. *TR

TL- THE CONTACT OWNS A 2010 TOYOTA PRIUS.

I HAVE A 2010 PRIUS, AND WHEN I APPLY THE BRAKES AT ANY INTENSITY AND MY VEHICLE HITS A DEFECT IN THE ROAD SURFACE, THE ABS SYSTEM SEEMS TO RELEASE BRAKE PRESSURE TO ALL 4 WHEELS COMPLETELY FOR ABOUT HALF A SECOND. THIS MAKES ME QUESTION THE EFFECTIVENESS OF THE BRAKES IN AN EMERGENCY SITUATION, ESPECIALLY ON HOUSTON'S NOTORIOUSLY NEGLECTED ROADWAYS. I WAS TOLD THAT THIS WAS NORMAL BY BOTH TOYOTA MOTOR CO. AT 1-800-331-4331 AND ALSO BY THE DEALER. TMC INFORMED ME THAT THIS IS THE WAY THAT THE ABS SYSTEM WAS DESIGNED. PLEASE LAUNCH AN INQUISITION AND/OR INVESTIGATION INTO THIS MATTER, FOR THE SAFETY OF THE OWNERS OF ALL TOYOTA PRIUS VEHICLES. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS BRAKING FROM APPROXIMATELY 30 MPH AND APPROACHING A TRAFFIC STOP WHEN THE BRAKES FAILED.

I PURCHASED A NEW 2010 TOYOTA PRIUS (MODEL 3) IN LATE JULY 2010. IN ALMOST EVERY RESPECT, THIS CAR IS WONDERFUL. HOWEVER, THE CAR HAS CONSISTENTLY DIMINISHED (APPARENT) BRAKING EFFECTIVENESS WHEN THE BRAKES ARE APPLIED AND THE CAR GOES OVER A PATCH OF ROUGH ROAD, POTHOLE, ETC. WHEN THE BRAKES ARE APPLIED WITH A CONSISTENT PRESSURE, THE CAR "FEELS" AS IF THE BRAKES DISENGAGE UPON ENTERING A ROUGH PATCH OF ROAD. THIS HAPPENS EVERY TIME. (FOR EXAMPLE, I NOTICE IT EVERY TIME I SLOW DOWN AT MY STREET CORNER WHERE THERE IS A LONG-STANDING PATCH OF ROUGH PAVEMENT.) SINCE 1994 I HAVE OWNED 7 CARS WITH ABS (HONDAS, NISSANS, AND TOYOTA CAMRYS), I HAVE NEVER EXPERIENCED A SIMILAR SENSATION IN ANY OF THESE OTHER CARS. I HAVE ADAPTED MY DRIVING STYLE TO THIS ANOMALY, BUT I WORRY ABOUT MY KIDS AND FRIENDS WHO MAY OCCASIONALLY DRIVE MY PRIUS. IT IS UNNERVING TO APPLY THE BRAKES AND HAVE THEM FEEL LIKE THEY ARE DISENGAGING WHEN YOU ENTER A ROUGH PATCH OF ROAD. SINCE THIS PROBLEM OCCURS CONSISTENTLY, I THINK IT SHOULD BE POSSIBLE TO TEST TO SEE IF THIS APPARENT BRAKING ANOMALY IS ACTUALLY INCREASING STOPPING DISTANCES. (FOR EXAMPLE, TEST PRIUS VS. MODEL WITHOUT APPARENT BRAKING ANOMALY ON SMOOTH AND ROUGH ROADS TO SEE IF RELATIVE BRAKING DISTANCES OF PRIUS ARE MORE HEAVILY AFFECTED BY ROUGH ROADS THAT COMPARISON MODEL.) P.S. AFTER PURCHASING MY NEW PRIUS, I NOTED THAT MY DEALER'S SERVICE BLOG, HAD SEVERAL REPORTS OF SIMILAR PROBLEMS THAT WERE NOT CORRECTED AFTER SERVICING BY THE DEALER. SOME POSTS NOTED THAT THE DEALER HAD APPLIED A SOFTWARE FIX THAT TOYOTA DISTRIBUTED IN EARLY 2010. MY CAR WAS MANUFACTURED AFTER THAT FIX. *TR

MY 2010 PRIUS' BRAKES DID NOT RESPOND WHILE ON THE ROAD ON 1/22/11. THEN 2X AGAIN ON 1/23/11. AS A CONSUMER, I DO NOT KNOW WHO REGULATES CAR COMPANIES BUT I HAVE CALLED THE MANUFACTURER AND THEY NEED TO 'DUPLICATE' THE PROBLEM. IN THE PAST, MY BRAKES WOULD ACCELERATE BEFORE IT WOULD CATCH AND THE PROBLEM WAS NOT 'DUPLICATED' BY THE DEALER. THIS TIME THE BRAKES FAILED ME 3X WITHIN 24 HOURS AND I AM EXTREMELY CONCERNED. I WOULD LIKE TO KNOW WHICH GOVERNMENT AGENCY TO REPORT IT TO AND WHAT BETTER OPTIONS I HAVE TO GET A RESOLUTION. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING OVER RAILROAD TRACKS SHE TRIED TO APPLY THE BRAKES AND THE PEDAL WENT ALL THE WAY DOWN TO THE FLOOR. THE CONTACT MENTIONED THAT SHE WAITED A COUPLE OF SECONDS BEFORE SHE APPLIED THE BRAKES AGAIN AND THEY FUNCTIONED NORMALLY. THE DEALER SAID THAT IT WAS NORMAL FOR THE VEHICLE TO FUNCTION THAT WAY ON UNEVEN SURFACES. THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WERE 22,000.

INCIDENT #1 ON JANUARY 5, 2011 - SUDDEN CHANGE IN BRAKING PERFORMANCE CAUSED CRASH. ACCIDENT OCCURRED IN COMPANY PARKING LOT. THERE WAS SNOW ON THE GROUND. I ATTEMPTED TO SLOW DOWN TO MAKE A RIGHT TURN. THE CAR INITIALLY STARTED TO SLOW DOWN. BUT AS I ATTEMPTED TO TURN TO THE RIGHT THE CAR STARTED TO SLIDE. I TRIED TO CONTROL THE SLIDE WITH THE BRAKES BUT THE CAR WOULD NOT SLOW DOWN AND IT SLID INTO A STONE CURB CAUSING OVER $1,700 IN DAMAGE TO THE CAR. THERE WAS NO FEELING OF ANY BRAKING OCCURRING. THERE WAS NO FEELING OF THE ABS BRAKES PULSING TO CONTROL THE SLIDE. INCIDENT # 2 ON JANUARY 19, 2011 - SUDDEN CHANGE IN BRAKING PERFORMANCE CREATED DANGEROUS STOPPING CONDITION. I WAS APPROACHING A RED LIGHT AT AN INTERSECTION GOING ABOUT 30 MPH. THERE WAS NO SNOW ON THE GROUND. THE ROAD WAS WET. I APPLIED THE BRAKES AND THE CAR INITIALLY STARTED TO SLOW DOWN. SUDDENLY THE BRAKES WERE NO LONGER SLOWING THE CAR DOWN. I THOUGHT THE CAR WAS GOING TO FAIL TO STOP AT THE INTERSECTION. I INCREASINGLY APPLIED MORE AND MORE PRESSURE ON THE BRAKE PEDAL AND THE CAR BEGAN TO SLOW DOWN. THE CAR DID FINALLY STOP AND DID NOT CROSS THE INTERSECTION. THE BRAKE PEDAL PRESSURE THAT I HAD TO APPLY WAS EXTREME - IT FELT LIKE A CAR WITH POWER ASSISTED BRAKES BUT THAT THE POWER ASSIST HAD FAILED. THERE WAS NO FEELING OF THE ABS BRAKES PULSING TO CONTROL THE BRAKING OF THE CAR.

ACCIDENT 12/22/10 TURNED LEFT AS I PULLED INTO PARKING SPACE NEAREST TO HANDICAPPED SPOT. IT WAS VERY SUNNY AND THERE WAS A PATCH OF WHAT LOOKED LIKE ICE. AS THE CAR WENT OVER THAT SPOT IT STARTED TO ACCELERATE. I APPLIED THE BRAKE, ONLY TO FIND MYSELF HITTING THE CURB. AFTER HITTING THE CURB THE CAR LURCHED OVER THE CURB AND I CONTINUED APPLYING THE BRAKE. IN A FRACTION OF A SECOND MY CAR WAS ON THE SIDE WALK, JUST BEFORE IMPACT WITH THE WALL I TOOK MY FOOT OFF THE BRAKE BECAUSE THE CAR DID NOT SEEM TO BE RESPONDING. I DIDN'T KNOW WHAT ELSE TO DO. IT WAS OVER IN SECONDS. BRICKS DENTED IN THE BUILDING, SMASHED GLASS. I PUT THE CAR IN REVERSE AND INTO THE PARKING SPOT. HEAD SPINNING AS TO HOW THIS HAPPENED. I WALKED INTO THE STORE AND APOLOGIZED. THERE WAS GLASS DUST STILL HANGING IN THE AIR. THE WOMAN INSIDE SAID 'CALL THE POLICE'. I THOUGHT THAT WAS A GOOD IDEA. I WAS EAGER TO DEMONSTRATED THAT I WASN'T DRUNK NOR USING ILLEGAL DRUGS. I OFFERED TO TAKE A BREATHILIZER, BUT THEY THOUGHT THAT WASN'T NECESSARY. *TR

TL*THE CONTACT OWNS 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 15 MPH AND APPLYING PRESSURE TO THE BRAKES, THE VEHICLE WOULD NOT STOP. THE VEHICLE WAS TAKEN TO THE DEALER BUT THE TECHNICIANS WERE UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER STATED THAT THEY COULD NOT ASSIST WITH REPAIRS IF THE FAILURE COULD NOT BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 1,000 AND CURRENT MILEAGE IS 6,000.

2010 TOYOTA PRIUS WAS PLACED IN "PARKING" IN MY HOME GARAGE, AS I TURNED OFF THE "HEATING" SWITCH TO THE SEAT, THE CAR ROLLED FORWARD ON ITS OWN AND HIT A WORK BENCH CHAIR IN FRONT OF THE VEHICLE. NO PERSONAL INJURY WAS SUSTAINED, BUT THE CAR HAD SOME DENTS TO THE FRONT END. *TR

I HAD TAKEN AN EXIT AFTER HAVING DRIVEN ABOUT 15 MILES ON HWY 85 & HAD MY FOOT OFF THE ACCELERATOR AS THERE WAS RED SIGNAL AHEAD. BEFORE COMING TO A FULL STOP THE LIGHT TURNED GREEN SO PUT MY FOOT ON THE ACCELERATOR BUT THAN HAD TO BRAKE ALMOST WITHIN SECONDS AS I SAW A CAR AHEAD AT THE NEXT GREEN LIGHT NOT MOVING. THE CAR FELT LIKE IT SURGED & DROVE WHAT I BELIEVE WAS ABNORMAL DISTANCE WITH MY FRONT CRASHING UNDER THE BACK OF AN OLD BUICK. I HAD 3 OTHER FAMILY MEMBERS IN THE CAR WHO FELT THE SAME JERK. THE ROAD WAS WET FROM PRIOR RAIN. THERE WAS NOT MUCH DAMAGE TO THE CAR I CRASHED INTO BUT MY CAR WAS CONSIDERED TOTAL LOSS, 15 MONTHS OLD WITH 28K MILES. NO AIR BAGS WERE DEPLOYED. IRONICALLY I HAD PICKED UP THE CAR FROM THE DEALERSHIP JUST THAT MORNING BECAUSE MY DAUGHTER HAD COMPLAINED ABOUT THE JERKING WHEN APPLYING BRAKES WHEN SHE DRIVES 20 MILES TO WORK IN A STOP & GO TRAFFIC ON HWY 280. THIS WAS NOT THE FIRST TIME SHE HAD COMPLAINED TO DEALERSHIP ABOUT THIS EITHER. THE DEALERSHIP LIKE BEFORE REPORTED NOTHING WRONG. THE CAR HAD THE SW UPGRADE DONE WHEN IT WAS RECALLED IN FEB/MAR. POST THE CRASH INCIDENT TOYOTA HAD THEIR EXPERT EXAMINE THE BRAKES WHO REPORTED, BRAKE RESERVOIR FLUID LEVEL 5MM ABOVE THE MAX LEVEL & SOME WHITE SUBSTANCE SUSPENDED IN IT NEAR THE SURFACE, BUT STILL BRAKE SYSTEM TO BE IN GOOD CONDITION.

THE DEALER INSPECTED AND STATED THAT THERE WAS NOTHING WRONG, THE FAILURE MILEAGE WAS 18,654 AND THE CURRENT MILEAGE WAS APPROXIMATELY 19,000. UPDATED 02/09/11*LJ UPDATED 03/03/11

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE STOPPED AT A TRAFFIC LIGHT, THE VEHICLE WAS HIT FROM THE REAR BY ANOTHER VEHICLE. AFTER THE VEHICLE WAS HIT, IT ACCELERATED TO A HIGH SPEED. THE CONTACT ENGAGED THE BRAKES BUT THE VEHICLE CONTINUED TO ACCELERATE; THE CONTACT ATTEMPTED TO TURN OFF THE IGNITION BUT THAT DID NOT STOP THE VEHICLE. THE VEHICLE CHANGED DIRECTIONS AND CROSSED OVER A GRASSY AREA AND CROSSED OVER THREE LANES OF TRAFFIC AND CRASHED INTO A CONCRETE MEDIAN. THE CONTACT STATED THAT ALL THE LIGHTS FAILED. THE TWO PASSENGERS WERE INJURED. A POLICE REPORT WAS FILED. THE VEHICLE WAS DESTROYED. THE VIN WAS UNAVAILABLE. THE CURRENT AND FAILURE MILEAGES WERE UNKNOWN.

I AM AN OWNER OF A 2010 TOYOTA PRIUS THAT WAS RECALLED FOR BRAKE PROBLEMS. THE AUTOMOBILE JOLTS FORWARD FOR A SPLIT SECOND WHEN THE BRAKES ARE APPLIED AND THE AUTOMOBILE ALSO PASSES OVER A BUMP OR POTHOLE. I TOOK THE AUTOMOBILE BACK TO THE DEALER PURSUANT TO THE RECALL TO BE FIXED. THE DEALER DID NOT FIX THE PROBLEM. THE PROBLEM REMAINS EVEN AFTER THE RECALL AND SUPPOSED REMEDY. I HAVE READ THAT OTHERS HAVE THE SAME ISSUE, AND THE PROBLEM HAS NOT BEEN CORRECTED BY THE RECALL IN OTHER CHATROOMS. I AM SURE THAT YOU ARE AWARE THAT THE RECALL DID NOT RESOLVE THE PROBLEM. *TR

MY 2010 TOYOTA PRIUS WOULD NOT START AFTER A BRIEF 45 MINUTE LUNCH WITH FRIENDS. WHEN I RELEASED THE PARKING BRAKE AND LET OFF THE BRAKE PEDAL I DIDN'T KNOW THE CAR WAS STUCK IN NEUTRAL. THIS ERROR WAS ON THE DASHBOARD "MALFUNCTION WHEN PARKING, PARK IN A FLAT PLACE AND APPLY PARKING BRAKE SECURELY". WHEN I LET OFF THE BRAKE THE CAR ROLLED BACK INTO THE MIDDLE OF THE PARKING LOT. I HAD TWO COWORKERS IN THE CAR WITH ME; THEY GOT OUT AND PUSHED THE CAR OUT OF THE WAY TO A FLAT LOCATION. CAR STILL WAS DISABLED. I CALLED TOYOTA ROADSIDE ASSISTANCE AND WAITED AN HOUR FOR A TOW TRUCK; AFTER ABOUT 45-50 MINUTES OF WAITING I WAS HIT BY A WOMAN THAT WASN'T PAYING ATTENTION; SHE BACKED INTO THE SIDE OF MY DISABLED CAR. I WAS PRESSING ON THE HORN AND SHE DIDN'T HEAR. THE IMPACT MUST HAVE FREED SOME STUCK COMPONENT OR SOMETHING BECAUSE 2 HOURS LATER WHEN THE TOW TRUCK FINALLY CAME, THE CAR WORKED AGAIN; NO WARNING LIGHTS ETC. TOYOTA LOOKED AT THE CAR AND SAYS THERE IS NOTHING WRONG. I TOOK A PHOTO TO DOCUMENT THE WARNING MESSAGE (PLUS HAVE 2 WITNESSES). *TR

THE BRAKES RELEASE FOR A "SECOND" OR TWO WHEN THE CAR HITS A BUMP, ESPECIALLY IN COLD OR WET WEATHER. MY CAR HAS SLID THROUGH INTERSECTIONS IN THE WINTER A NUMBER OF TIMES BECAUSE OF THIS. I HAVE TO START BRAKING THREE BLOCKS AHEAD IN BAD WEATHER BECAUSE I NEVER KNOW WHEN THE BRAKES WILL RELEASE. THIS IS VERY DANGEROUS. *TR

SAME AS EVERYONE ELSE: WHEN BRAKING WHILE TURNING OVER UNEVEN PAVEMENT, BRAKES SEEM TO ACCELERATE OR LOOSEN TEMPORARILY. SO WHEN IS NHTSA GOING TO DO SOMETHING ABOUT THIS? OR ARE THEY WAITING FOR A "SIGNIFICANT" NUMBER OF DEATHS FIRST? *TR

2010 TOYOTA PRIUS. S10 APPROPRIATE HANDLING- LETTER FROM REGARDING TOYOTA PROBLEMS *TGW THE CONSUMER STATED WHEN HE WENT TO START HIS VEHICLE, THE BRAKE PEDAL WENT STRAIGHT DOWN TO THE FLOOR AND THE VEHICLE WOULD NOT START UNTIL PRESSURE WAS APPLIED TO THE BRAKE. AFTER TRYING SEVERAL THINGS, THE BRAKE FINALLY CAME ON. THE CONSUMER TOOK THE VEHICLE TO THE DEALER, BUT THEY WERE UNABLE TO FIND ANYTHING WRONG. ON APRIL 27, 2010, THE INCIDENT HAPPENED AGAIN WITH THE BRAKES. A NOTICE APPEARED ON THE DASH TO PUT THE VEHICLE IN PARK. WHEN HE DID, THE BRAKE CAME ON. *JB UPDATED 12/22/10.*JB

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE WAS REPAIRED FOR THE RECALL ASSOCIATED WITH NHTSA CAMPAIGN ID NUMBER 10V039000, SERVICE BRAKES, AIR ANTILOCK CONTROL UNIT/MODULE. UPON RECEIVING THE VEHICLE HE WAS DRIVING APPROXIMATELY 30 MPH WHEN HE APPLIED THE BRAKES WHILE DRIVING OVER A BUMPY SURFACE. ONCE HE DROVE OVER THE BUMPY SERVICE THE BRAKES STOPPED WORKING. HE WAS FORCED TO APPLY PRESSURE TO THE BRAKES IN ORDER TO SLOW THE VEHICLE DOWN. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER ON FOUR OCCASIONS WHERE THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 1,500 AND THE CURRENT MILEAGE WAS 11,102. THE VIN WAS UNAVAILABLE.

LOSS OF BRAKING EFFECTIVENESS. HAPPENS WHEN GOING OVER BUMPS WHILE APPLYING THE BRAKES. YOU DON'T LOSE BRAKING POWER COMPLETELY, BUT IT WOULD BE LIKE YOU HAD LIFTED YOUR FOOT OFF THE BRAKES PARTIALLY. IT HAS HAPPENED ABOUT A DOZEN TIMES SINCE I HAVE OWNED THE VEHICLE (A LITTLE OVER A YEAR). I AM UNABLE TO DETERMINE WHAT FACTORS MAKE IT HAPPEN. I DON'T KNOW IF IT IS SPEED, SEVERITY OF THE BUMPS, OR BRAKING PRESSURE, OR COMBINATION. I KNOW THAT TEMPERATURE MAKES NO DIFFERENCE, AS IT HAS HAPPENED IN WINTER AND SUMMER. THE LAST INCIDENT HAPPENED WHEN A BICYCLIST MOVED IN FRONT OF MY CAR TO AVOID BUMPS. I APPLIED THE BRAKES (IT WAS NOT SEVERE), AND AS I WENT OVER THE BUMPS, I LOST BRAKING POWER. MY SPEED WAS APPROXIMATELY 15 MPH. TOYOTA HAS DONE A RECALL ON THE BRAKES, BUT I CONTINUE TO HAVE THE PROBLEM. I HAVE TALKED TO OTHER OWNERS, AND THEY ARE HAVING THE SAME PROBLEM, EVEN AFTER THE RECALL. THE CONSUMER STATED WHEN HE DROVE OVER A BUMP IN THE ROAD, THE BRAKING DECREASED SIGNIFICANTLY FOR APPROXIMATELY 3 SECONDS. HE ALSO STATED THE ENGINE RACED BRIEFLY, BUT THE VEHICLE WAS NOT IN GEAR AT THE TIME. UPDATED IVOQ 03/01/11 *TR

EVEN AFTER THE BRAKE RECALL REPAIR HAS BEEN PERFORMED, MY CAR'S BRAKES SUDDENLY AND MOMENTARILY LOSE BRAKING POWER OVER UNEVEN OR ROUGH SURFACES. PROBLEM SEEMS COMPOUNDED WHEN TURNING. *TR

I OWN A NEW 2010 PRIUS. IT HAS 1800 MILES ON IT. WHILE DRIVING WITH SOMEONE ELSE IN THE PRIUS, THERE WAS A BRAKING PROBLEM. WE BOTH FELT A LOSS OF BRAKING BY THE PRIUS WHEN I WAS BRAKING FOR A RIGHT TURN AND WENT OVER A BUMPY SECTION ON THE ROAD SURFACE. THE PRIUS EXPERIENCED A MOMENTARY COMPLETE LOSS OF BRAKING OVER THE BUMPS. IT FELT LIKE WE ACTUALLY ACCELERATED FOR AN INSTANT. IN ANY CASE, THE BRAKE PEDAL WAS ENGAGED FIRMLY THE WHOLE TIME. THE PRIUS THEN SLOWED DOWN NORMALLY, AND I MADE THE TURN AT THE CORNER. BUT WE BOTH LOOKED AT EACH OTHER IN SURPRISE AT WHAT WE FELT DURING THAT BRAKING EVENT LEADING INTO THE TURN. I CALLED THE DEALER AND HAD THEM LOOK UP THE COMPUTER PATCH HISTORY ON THIS CAR. THE DEALER STATED THAT ALL THE COMPUTER PATCHES HAD ALREADY BEEN APPLIED TO THIS CAR BEFORE IT WAS DELIVERED AS NEW. SO FAR, THIS HAS ONLY HAPPENED ONCE. I HAVE BEEN DRIVING THE NEW PRIUS FOR ONLY 1800 MILES. IT WAS PURCHASED NEW OFF THE DEALER LOT AUG 2010. IT HAPPENED IN OCT 2010. EXTREME LOSS OF BRAKING OVER BUMPY ROAD SURFACE. I HAVE MANY YEARS OF DRIVING EXPERIENCE IN MANY TYPES OF CARS ON MANY DIFFERENT ROAD SURFACES. I HAVE NEVER EXPERIENCED THIS TYPE OF MOMENTARY COMPLETE BRAKE LOSS BEFORE. *TR

2010 TOYOTA PRIUS, NO ACCIDENTS, BUT CLOSE CALLS. WHEN I AM SLOWING TO A STOP, AND IF THE VEHICLE HITS A ROUGH SPOT IN THE ROAD, FOR EXAMPLE A POTHOLE, THE BRAKE PEDAL LOWERS SLIGHTLY AND THE CAR APPEARS TO HAVE THE ANTI LOCK BRAKING TAKE OVER AND THE CAR SPEED DECREASES SLOWLY UNDER THE CONTROL OF THE ABS AND MAY NOT STOP IN THE REMAINING DISTANCE TO A STOP SIGH OR TRAFFIC LIGHT. AT LEAST 4 TIMES, 3 SINCE THE SOFTWARE UPDATE FOR MY CAR, I HAVE BEEN STOPPING AND WITHIN ABOUT 20 FEET OF THE STOP SIGH THERE WAS A SIGNIFICANT BUMP OR POTHOLE AND WITH MY FOOT ON THE BRAKE CONTINUOUSLY I NOTICED THAT THE BRAKE PEDAL DEPRESSED SLIGHTLY AND MY RATE OF SLOWING DECREASED AND MY CAR DRIFTED PAST THE STOP SIGN. THIS ALL HAPPENED WITH MY FOOT STILL ON THE BRAKE. I TOLD THE TOYOTA DEALER ABOUT THIS AND WAS INFORMED THAT IT IS THE WAY THE CAR IS DESIGNED, THAT ANY TIME THAT THE COMPUTER SENSES A WHEEL SLIP, THE ABS TAKES OVER. BUT ON DRY ROAD CONDITIONS, THIS IS PROBLEMATIC BECAUSE IN MY AREA THERE ARE OFTEN UN REPAIRED ROADS WITH RUTS, POTHOLES, BUMPS AND ETC. NEAR THE INTERSECTIONS. HAVING THE ABS TAKE OVER PROVIDES A LAG TIME IN THE STOPPING OF THE CAR AND EACH TIME I HAVE GONE PAST THE STOP SIGN AND SLIGHTLY INTO THE INTERSECTION APPROXIMATELY 5 FEET INTO THE PATH OF OTHER VEHICLES. I AM AN ENGINEER WITH NASA AND KNOW WHAT I AM DOING AND HAVE BEEN TOLD THAT THIS IS A DESIGN FEATURE, BUT THIS FEATURE CAN AND HAS LEFT ME EXCEEDING MY PLANNED STOPPING DISTANCE AND COULD HAVE LEAD TO AN ACCIDENT. *TR

ON 2010 PRIUS, BRAKES SEEM TO RELEASE, GENERALLY FOR A MOMENT, AT LOW SPEEDS WHEN GOING OVER A BUMP ON PASSENGER SIDE OF THE CAR. CAR SEEMS TO ACCELERATE MOMENTARILY, UNTIL BRAKES ARE HIT AGAIN. THIS HAS HAPPENED A NUMBER OF TIMES BUT IS SOMETIMES HARD TO RECREATE. CAR HAS 3000 MILES. DEALER SAYS BRAKES OPERATING AS DESIGNED AND RECALL ADJUSTMENT HAS BEEN MADE. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE TRAVELING 2 MPH THE CONTACT APPLIED THE BRAKES AND NOTICED THAT THEY WOULD NOT ENGAGE CAUSING THE CONTACT TO CRASH INTO A WALL. NO ONE WAS INJURED AND A POLICE REPORT WAS NOT FILED FOR THE INCIDENT. THE VEHICLE WAS TAKEN TO THE DEALERSHIP WHERE THE CONTACT WAS INFORMED THAT THE FAILURE COULD NOT BE REPRODUCED. THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 1500.

DESPITE THE COMPUTER UPDATE FOLLOWING THE RECALL MY 2010 TOYOTA PRIUS CONTINUES TO HAVE BRAKING PROBLEMS. SINCE THE UPDATE THE CAR ACCELERATES SLIGHTLY WHEN AN UNEVEN ROAD SURFACE IS ENCOUNTERED WHILE BRAKING. TOYOTA SAYS THIS IS NORMAL OPERATION. *TR

2010 TOYOTA PRIUS OCCASIONAL LOSS OF BRAKE PERFORMANCE IMMEDIATELY UPON START-UP OF VEHICLE. ON 4 SEPARATE OCCASIONS, THERE WAS NOTED LOSS OF BRAKING CAPABILITY AFTER SHIFTING INTO REVERSE IMMEDIATELY AFTER TURNING ON THE IGNITION. THIS CAUSED THE BRAKE PEDAL TO FEEL HARD, AND ALLOWED THE CAR TO SLOWLY MOVE AGAINST THE OPERATOR'S INTENTIONS. AFTER ABOUT 5 SECONDS, THE BRAKES BEGIN TO FUNCTION NORMALLY. A TOYOTA DEALERSHIP TOLD ME IT TAKES A FEW SECONDS FOR BRAKE PRESSURE TO COME UP AFTER STARTING THE VEHICLE AND THAT I SHOULD WAIT BEFORE SHIFTING INTO GEAR. THIS INSTRUCTION SEEMS COUNTERACTIVE TOWARDS SAFETY, AND THE VEHICLE SHOULD NOT BE ALLOWED TO SHIFT INTO GEAR UNTIL BRAKE PRESSURE IS PRESENT. A SIMPLE SOFTWARE UPDATE SHOULD BE ABLE TO ADDRESS THIS CONCERN. *TR

SQUEALING NOISE FROM BRAKES/WHEELS WHEN I PRESS BRAKES ON MY BRAND NEW 2010 TOYOTA PRIUS. IT'S LITERALLY CAUSING ME HEADACHES AFTER DRIVES AND IS A BIG HEALTH HAZARD. I HAVE TAKEN THE CAR TWICE TO MY DEALERSHIP THAT SOLD THE CAR AND THEY ARE RECOGNIZING THE NOISE BUT TELLING THAT IT IS NORMAL FOR ALL PRIUS. IF THAT'S THE CASE THEN IT'S A DEFECT IN PRIUS AS SQUEALING NOISE THAT CAUSES HEADACHES SHOULD NOT BE NORMAL. ALSO, I AM NOT THE ONLY ONE FACING THIS.

MY 2010 TOYOTA PRIUS HAS ALWAYS HAD PROBLEMS BRAKING OVER BUMPY ROADS. AT CERTAIN SPEEDS FIRM BRAKING OVER BUMPS CAUSES THE WHEELS TO FEEL LIKE THEY ARE SLIPPING. TOYOTA RECALLED THE VEHICLE, AND PERFORMED SOFTWARE UPGRADES THAT I FEEL DID NOTHING TO IMPROVE THE SITUATION. I RECENTLY BROUGHT THE CAR BACK TO BE SERVICED AND MENTIONED THAT IT WAS STILL SLIPPING OVER BUMPS BUT THEY CLAIMED THAT THEY COULD NOT REPLICATE THE PROBLEM. THIS IS NOT ONE SPECIFIC INCIDENCE BUT MULTIPLE INSTANCES. *TR

1. PULLING IN TO A PARKING SPACE, SLIGHT UPHILL ANGLE, STEPPED ON BRAKE AND CAR LURCHED FORWARD OVER A BARRIER AND INTO ANOTHER VEHICLE. 2. THE VEHICLE GAVE NO PRIOR INDICATION OF A PROBLEM. EXTENSIVE DAMAGE TO HOOD, BUMPER, RIGHT FENDER AND RADIATOR. 3. VEHICLE WAS TOWED TO A REPAIR FACILITY. ONCE REPAIRED, VEHICLE WAS TAKEN TO DEALER FOR DIAGNOSTIC OF BRAKE FAILURE PROBLEM WHERE IT CURRENTLY REMAINS. *TR

2010 PRIUS WHEN ATTEMPTING TO STOP IF VEHICLE HITS BUMPS, POTHOLES, MANHOLES, ETC., THE VEHICLE BRAKING SYSTEMS LETS GO FOR A MOMENT AND THE VEHICLE WILL KEEP MOVING FORWARD. I HAVE HAD MY PRIUS INTO MY SERVICE DEPARTMENT FOR THE "RECALL" BUT THE PROBLEM CONTINUES. MY SERVICE DEPARTMENT HAS BEEN IN CONTACT WITH TOYOTA WHO TELLS THEM IT IS A CHARACTERISTIC OF THE VEHICLE AND TO ADVISE OWNER OF SUCH. THIS IS A CLEAR SAFETY ISSUE WITH THE VEHICLE. MY FAMILY WILL NOT DRIVE THE CAR AND MY FRIENDS WON'T GET IN THE CAR BECAUSE OF THIS PROBLEM. I WAS TOLD TO EITHER LIVE WITH THE VEHICLE OR TRADE IT IN. NOT AN ACCEPTABLE ANSWER IN MY BOOK. THIS CAN HAPPEN WITH THE VEHICLE 5 OR MORE TIMES A DAY DEPENDING ON WHERE I AM DRIVING. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 20 MPH OVER ROUGH TERRAIN THE CONTACT APPLIED THE BRAKES AND THEY FAILED TO ENGAGE. THE VEHICLE WAS NOT REPAIRED NOR WAS THERE A DIAGNOSTIC TEST PERFORMED. THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 6000.

WAS DRIVING PRIUS 2010 MODEL II WITH BRAKE SOFTWARE APPLIED BY DEALER ABOUT 1.5 MONTHS AGO. TODAY (7/27/2010) I EXITED HIGHWAY AND BEGAN GENTLE BRAKING ON OFFRAMP, AS SUGGESTED BY MANUAL TO MAXIMIZE REGENERATION. ABOUT HALF-WAY DOWN OFFRAMP, I REALIZED CAR IN FRONT OF ME WAS COMPLETELY STOPPED AND THAT I HAD TO STOP MUCH MORE QUICKLY THAN I WAS PLANNING TO. I DON'T RECALL BEING PARTICULARLY DISTRACTED, BUT I CAN'T RULE OUT I NOTICED THE STOPPED VEHICLE LATER THAN I SHOULD HAVE. IN ANY EVENT, I'M NOT SURE HOW HARD I PRESSED THE BRAKES, BUT I RECALL DISTINCTLY THINKING "OH, MY GOD. NOTHING IS HAPPENING" AND 1-2 SECS LATER I PLOWED INTO THE CAR IN FRONT OF ME. THE COLLISION WAS HARD ENOUGH TO CAUSE TEMPORARY PAIN TO THE DRIVER IN FRONT OF ME, BUT NO AIR BAGS WERE DEPLOYED AND THE PRIUS APPEARS TO NOT HAVE MAJOR FRONTAL DAMAGE - HOOD IS BENT BACK AND MAYBE SLIGHT FRAME DISTORTION => THE IMPACT CLEARLY WAS NOT AT THE ~40-50 MPH I WAS GOING WHEN JUST EXITING THE HIGHWAY, SO SOME BRAKING CLEARLY DID OCCUR -- BUT I HAVE THE DISTINCT FEELING THAT MY PREVIOUS CAR (SUBARU OUTBOOK) WOULD HAVE EASILY STOPPED IN TIME. AFTER ACCIDENT, I TESTED BRAKES BY GOING 15-20 MPH IN PARKING LOT AND BRAKING HARD. ALWAYS STOPPED QUICKLY, I'M GUESSING W/100% FRICTION BRAKING. SO BRAKES ARE PROBABLY NOT "DEFECTIVE" IN SENSE OF LOST HYDRAULIC FLUID, ETC... BUT I HAVE NEVER BEFORE EXPERIENCED THE FEELING "I'M NOT STOPPING" EXCEPT ONCE WHEN LOSING TRACTION ON ICY ROAD WITH A NON-HYBRID. THE FACT HAD TIME TO THINK THIS THOUGHT AT ALL PROBABLY MEANS MAYBE 0.5-1.5 SEC PASSED WHILE BRAKING INEFFECTIVE. CHECKED FOR TIRE/SKID MARKS ON ROAD OR EVIDENCE OF STRONG TIRE WEAR AND FOUND NONE, WHILE I HAVE ON OTHER CARS WHEN I HAVE HAD TO BRAKE HARD => PRIUS NOT BRAKING HARD DESPITE EMERGENCY. SEEM TO HAVE BEEN CAUGHT IN TRANSITION BETWEEN REGEN & FRICTION MODE? THIS IS STILL DISCUSSED IN PRIUS FORUMS -- SOFTWARE FIX NOT GOOD ENOUGH!? THIS IS POTENTIALLY VERY DANGEROUS. BTW,CAR WAS IN "ECO" MODE. *TR

I HAVE BEEN EXPERIENCE MOMENTARY LOSS OF BRAKING POWER WHILE DRIVING MY 2010 PRIUS ON ROUGH ROAD SURFACE OR POTHOLES MORE THAN 30 TIMES SINCE I OWN THIS VEHICLE. I FILED A COMPLAINT (ODI #10304434) BACK IN FEB 3RD. 2010 BEFORE THE RECALL FROM TOYOTA. MY PRIUS WAS INCLUDED IN THE RECALL, SO I BROUGHT THE VEHICLE BACK TO TOYOTA SERVICE CENTER FOR THE RECALL. TOYOTA UPDATED THE ABS ECU SOFTWARE ON MY PRIUS ON FEB. 2010. SINCE TOYOTA UPDATED THE SOFTWARE FOR THE RECALL, I STILL EXPERIENCE THE SAME PROBLEM MULTIPLE TIMES, AND IT IS NOT ONLY HAPPEN DURING SLOW AND STEADY APPLICATION OF BRAKES, ALSO HAPPEN WHEN I USE THE BRAKE IN MORE SUDDEN FASHION EVEN AT MODERATE SPEED (30-40MPH). I BROUGHT MY PRIUS BACK TO THE TOYOTA SERVICE CENTER AGAIN IN MAY 2010 TO RECHECK THE ABS ECU SOFTWARE, AND THEY SAID THE SOFTWARE IS THE LATEST UPDATED VERSION, AND MY BRAKING SYSTEM IS MEETING THE MANUFACTURE SPECIFICATION. HOWEVER, THIS PROBLEM IS STILL EXIST AS OF TODAY, AND MY CONCERN REGARDING SAFETY OF THIS VEHICLE IS GROWING BECAUSE THIS PROBLEM LEAD TO INCREASE VEHICLE STOPPING DISTANCE AND THUS RAISE THE LIKELIHOOD OF A CRASH OR ACCIDENT. *TR

TL* THE CONTACT'S BROTHER OWNED A 2010 TOYOTA PRIUS. THE CONTACT STATED HER BROTHER DIED IN A HEAD ON CRASH. WHILE HE WAS DRIVING AT APPROXIMATELY 65MPH NORTH BOUND, A TRUCK WAITING AT A TRAFFIC LIGHT WAS REAR ENDED BY ANOTHER TRUCK PUSHING THE TRUCK INTO THE CONTACT'S BROTHER LANE OF TRAFFIC. THE CONTACT STATED WITNESSES ADVISED HER THAT BRAKES FAILED ON HER BROTHER'S VEHICLE AND HE WAS NOT ABLE TO BRING THE VEHICLE TO STOP WHEN HE SAW THE TRUCK APPROACHING. THE POLICE REPORT WAS NOT AVAILABLE. THE VIN WAS UNKNOWN. THE FAILURE AND THE CURRENT MILEAGE WAS 21,000.

TOYOTA PRIUS ACCELERATES SUDDENLY WHEN DRIVEN OVER BUMPS, SUCH AS SPEED BUMPS OR OTHER BUMPS IN THE ROAD, USUALLY WHEN GOING UNDER 30MPH, AND OFTEN WITH THE BRAKES BEING LIGHTLY PRESSED. *TR

TOYOTA PRIUS BRAKING PROBLEM; I HAD THE "RECALL" FIX APPLIED; I HAVE NOTICED IN THE LAST TWO WEEKS THAT THE CAR HAS STARTED TO HAVE BRAKE FAILURE AGAIN WHEN GOING OVER BUMPY SURFACES. IT HAD BEEN FINE FOR A WHILE, BUT THIS STARTED HAPPENING AGAIN. I HAVE CONTACTED DEALERSHIP REGARDING THE SAME. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHENEVER SHE DROVE OVER A POT HOLE OR RAILROAD TRACKS THE BRAKING SYSTEM DID NOT FUNCTION PROPERLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THE FAILURE WAS DUE TO A DESIGN FLAW. THE VEHICLE WAS NOT REPAIRED. UPDATED 10/28/10.*LJ UPDATED 10/28/10

BRAKES DO NOT WORK WHEN DECELERATING AND ROAD IS UNEVEN OR BUMPY. WE TOOK THE CAR IN FOR THE RECALL FIX AND THE PROBLEM PERSISTS. BRAKE FAILURE HAPPENS 3-4 TIMES/ WEEK DRIVING IN SEATTLE. *TR

WHEN ATTEMPTING TO STOP OUR 2010 TOYOTA PRIUS, THE CAR LURCHED FORWARD, AND CONTINUED TO MOVE. I LET OFF THE BRAKE PEDAL, AND REAPPLIED THE BRAKES, BUT THEY DID NOTHING FOR ABOUT 30 SECONDS - AT WHICH POINT THE CAR STOPPED. AFTER CONTACTING BOTH OUR TOYOTA DEALERSHIP, AND THE TOYOTA CUSTOMER SERVICE DEPARTMENT, THEY WILL NOT LOOK AT THE CAR UNTIL NEXT WEEK. *TR

GRABBING BRAKES: PARKED AND SAT IN THE CAR ON A SLIGHT INCLINED DRIVEWAY FOR SOME TIME LISTING RADIO. WHEN I STARTED BACKING UP AND TRIED TO BRAKE, THERE WAS NO BRAKING AND THEN CLUNK CLUNK NOISE AND CAR STOPS, TRIED AGAIN, SAME THING NO BRAKING AND THEN LITTLE MORE PRESSURE ON BRAKES, CLUNK CLUNK NOISE CARS STOPS. THERE WAS NO WAY TO SMOOTHLY GLIDE THE CAR DOWN. THIS HAPPENED AROUND 5 TIMES. DURING LAST SERVICE I EXPLAINED DEALER ABOUT THE PROBLEM BUT THEY COULD NOT REPRODUCE IT. *TR

WHILE BRAKING AND THE CAR IS SLOWING DOWN TO BELOW ABOUT 10 MILES AN HOUR, IT WILL SURGE AHEAD IF IT GOES OVER ROUGH PAVEMENT OR A BUMP. THE ABS RECALL HAS BEEN PERFORMED ON THE CAR, AND IT WAS BROUGHT BACK INTO THE DEALER AFTER THE RECALL AND THE DEALER CONFIRMED THAT THE RECALL WAS APPLIED. THE DEALER CLAIMS THAT THIS BEHAVIOR IS "NORMAL". THE CAR HAS BEEN BACK TO THE DEALER TWO TIMES SO FAR. *TR

LIKE ALL OTHER 2010 PRIUS COMPLAINTS, WHEN I APPLY THE BRAKES AND GO OVER A BUMPY SURFACE, THE BRAKES RELEASE CAUSING THE CAR TO JOLT FORWARD. I TOOK MY 2010 TOYOTA PRIUS IN TO THE DEALER DUE TO THE RECALL. THE SERVICE MANAGER STATED MY CAR WOULD BE FIXED IN LESS THAN THIRTY MINUTES. WHATEVER THEY WERE SUPPOSED TO DO TO FIX THE BRAKE PROBLEM DID NOT HAPPEN OR DID NOT WORK. MY CAR STILL JOLTS FORWARD WHEN I AM PRESSING ON THE BRAKES AND I HIT A BUMPY SURFACE. I AM SCARED FOR MY OWN SAFETY. IN ADDITION, I CANNOT HELP BUT WONDER WHAT THIS PROBLEM DOES TO MY TIRES. I HAVE HAD THE CAR SINCE JULY 2009 AND HAVE GOTTEN TWO FLAT TIRES IN THE PAST 11 MONTHS! I HAVE PUT SO MUCH TIME AND MONEY IN TO THIS CAR, AND I HAVEN'T EVEN HAD IT FOR A FULL YEAR. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHEN DRIVING OVER A POT HOLE OR ANY UNEVEN ROAD SURFACE, THE VEHICLE WOULD EXHIBIT A DELAY IN BRAKING. THE BRAKES WOULD HESITATE TO ENGAGE WHEN DEPRESSED. THE DEALER ADVISED THE VEHICLE WAS UNDER NHTSA RECALL CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR; ANTILOCK: CONTROL UNIT/MODULE) AND RECEIVED THE RECALL REPAIRS. THE FAILURE PERSISTED AFTER REPAIRS. IN ADDITION, THE BRAKES WOULD SPORADICALLY BECOME STUCK WHEN BRAKING IN REVERSE AND THE THEN WOULD BEGIN TO JERK VIOLENTLY. THE VEHICLE WAS NOT FURTHER REPAIRED. THE FAILURE MILEAGE WAS 9,000 AND THE CURRENT MILEAGE WAS 11,786.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHEN DRIVING DOWNHILL AND ATTEMPTING TO BRAKE, THE BRAKES WOULD NOT ENGAGE AND INTERMITTENTLY COULD NOT BE DEPRESSED.

WE PURCHASED A 2010 PRIUS IN MAY 2010. MY WIFE DROVE THE CAR OUT OF A SHOPPING MALL DRIVEWAY INTO THE LEFT HAND TURN OF THE ROAD AND PULLED UP BEHIND A TRUCK. SHE WAS TRAVELING ABOUT 5-10 MPH ON A NORMAL ROAD, NO POT HOLES OR WET CONDITIONS. SHE HAD HER FOOT RAMMED TO THE FLOOR BUT NO BRAKES! SHE WENT INTO THE BACK OF THE TRUCK, CAUSING EXTENSIVE DAMAGE TO THE FRONT OF THE CAR AND WINDSCREEN. SHE HAD TWO CHILDREN IN THE BACK WITH HER. SEEMS LIKE THEY HAVE NOT FIXED THE PROBLEM! WE WERE TOLD BY DEALERSHIP THAT THERE WERE NO PROBLEMS AND THAT EVERY CAR ON THE LOT HAD BEEN FIXED! NOT REPAIRED YET. NOT SURE I WANT IT BACK. *TR

I OWN A 2010 TOYOTA PRIUS, AND LAST WEEK I HAD THE ABS ECU UPDATED PER THE RECALL. PRIOR TO THE UPDATE, BRAKING OVER A BUMP OR POTHOLE WOULD RESULT IN A LITTLE 'SKIP' ON THE ROAD AS THE BRAKES KIND OF FLUTTERED. I JUST PRESSED THE PEDAL A LITTLE HARDER AND ALL WAS WELL. POST UPDATE, I HAVE A SERIOUS SAFETY PROBLEM. I HAVE EXPERIENCED THE BRAKES DISENGAGING COMPLETELY AS THE CAR HITS A BUMP. THE LITTLE 'SKIP' IS GONE, AND NOW THERE'S A PANIC MOMENT WHERE THE CAR LURCHES FORWARD WITH NO BRAKE PRESSURE. I HAVE TO REALLY MASH THE PEDAL THE GET THE BRAKES BACK. PRIOR TO THE UPDATE I WAS A LITTLE WORRIED THAT THE SLIGHT INCREASE IN BRAKING DISTANCE MIGHT HAVE RESULTED IN A CRASH. NOW, I AM VERY AFRAID. THE CAR IS ALMOST UNCONTROLLABLE WHEN THIS HAPPENS, AND IT IS ALWAYS UNEXPECTED. I FEEL THAT IF I CRASH, I WILL BE HELD LIABLE FOR SOMETHING THAT ISN'T MY FAULT. I ASK THE NHTSA TO REVISIT THE TOYOTA RECALL FOR THE 2010 PRIUS AND MAKE THEM PROVE THEY FIXED THE PROBLEM. I DO NOT THINK THEY WILL BE ABLE TO. *TR

I HAVE A 2010 PRIUS THAT HAS HAD THE BRAKE RECALL FIX APPLIED. BUT WHEN I AM TURNING RIGHT APPLYING THE BRAKE AND THEN HIT BUMP/CHUCK HOLE THE BRAKES FADE FOR JUST A FEW SECONDS. NO ACCIDENTS BUT DOES NOT GIVE DRIVER ANY CONFIDENCE. *TR

SEVERE BRAKE GRAB IN SLOW SPEED REVERSE OR FORWARD. VERY INTERMITTENT. RESEARCH SHOWS SAME COMPLAINT FOUND IN NUMEROUS COMPLAINTS ON THE NHTSA SITE. DEALER AND TOYOTA UNAWARE AND WERE OF NO HELP IN RESOLUTION. *TR

I OWN A 2010 TOYOTA PRIUS. I WAS HAVING BRAKING ISSUES BEFORE THE SAFETY RECALL. IT WOULD ACCELERATE WHEN I HIT A BUMP WHILE BRAKING. I TOLD BROUGHT MY VEHICLE IN FOR THE FIRST DAY OF THE RECALL AND IT WAS "FIXED." NOW THE PROBLEM IS BACK. MY CAR SUDDENLY ACCELERATES WHEN I'M SLOWING DOWN/BRAKING AND HIT A BUMP. *TR

2010 PRIUS - THIS CAR WAS RECALLED FOR A BRAKING PROBLEM. THE "SOFTWARE FIX" WAS COMPLETED ON MY CAR, BUT THE SAME BRAKING PROBLEM STILL EXISTS IN THE CAR. A FOLLOW-UP VISIT TO THE DEALER COMPLAINING OF THE PROBLEM STILL HAPPENING RESULTED IN NOTHING BEING DONE TO FIX THE BRAKING PROBLEM. THE PROBLEM : OCCASIONALLY WHEN BRAKING OVER A BUMP THE BRAKES DISENGAGE FOR A BRIEF TIME (PROBABLY LESS THAN A SECOND) AND RESULT IN AN INCREASED STOPPING DISTANCE AND POSSIBLE ACCIDENT. IN OTHER WORDS THE RECALL FIX HAS DONE NOTHING TO CORRECT THE PROBLEM - - IF IT WAS BAD ENOUGH TO HAVE A RECALL - AND IT DOESN'T GET FIXED - THEN IT MUST STILL BE A SIGNIFICANT PROBLEM.... THIS PROBLEM OCCURS OFTEN - BUT NOT EASILY DEMONSTRATED. IT HAS HAPPENED SINCE THE CAR WAS NEW AND WE NOW HAVE 11,000 MILES AND IT STILL HAPPENS. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE WAS PREVIOUSLY REPAIRED UNDER NHTSA CAMPAIGN ID NUMBER: 10V039000 (SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE). AFTER RETRIEVING THE VEHICLE FORM THE AUTHORIZED DEALER, THE VEHICLE WOULD EXHIBIT AN INCREASED STOPPING DISTANCE WHEN BRAKING FROM LOWER SPEEDS. THE FAILURE BEGAN TO RECUR INTERMITTENTLY. THE FAILURE MILEAGE WAS 3,000 AND THE CURRENT MILEAGE WAS 14,000.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHEN BRAKING FROM SPEEDS OF AT LEAST 30 MPH, THE VEHICLE WOULD ABNORMALLY SURGE FORWARD. THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT STATED THE FAILURE HAD OCCURRED SINCE THE DATE OF PURCHASE AND CONTINUED TO RECUR INTERMITTENTLY. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 300 AND THE CURRENT MILEAGE WAS 9,650.

TODAY AT YET ANOTHER CHECK FOR MY 2010 PRIUS TO TRY TO DISCOVER THE CAUSE FOR THE CONTINUAL SURGING, I WAS INFORMED THAT 160 TIMES IN THE LAST 1 1/2 MONTHS I HAVE DRIVEN WITH BOTH THE GAS AND BRAKE PEDALS DEPRESSED SIMULTANEOUSLY. THIS IS A RIDICULOUS ASSERTION AND COMPLETELY FALSE. OBVIOUSLY THERE IS AN ISSUE WITH THE COMPUTER SOFTWARE IN MY PRIUS BRAKES. THIS IS FURTHER EVIDENCE THAT THERE IS A SERIOUS SAFETY ISSUE WITH THE PRIUS BRAKES. *TR

I WAS DRIVING THE CAR ON A ROAD APPROX. 25 MPH. I HIT A DIP IN THE ROAD RIGHT AS I WAS BRAKING TO MAKE A LEFT TURN. THE AUTOMOBILE SURGED FORWARD DESPITE MY FOOT BEING ON THE BRAKE. THIS HAS HAPPENED REPEATEDLY SINCE HAVING THE RECALL FIX!!! THIS PROBLEM MUST BE FIXED. WE HAVE REPEATEDLY CONTACTED TOYOTA ABOUT THE PROBLEM AND GET THE SAME ANSWER EVERY TIME - THERE IS NO PROBLEM. I DO NOT CONSIDER IT TO BE NORMAL FOR THE CAR TO SURGE FORWARD WHILE MY FOOD IS FIRMLY ON THE BRAKE. WHAT DOES IT TAKE TO GET SOMETHING DONE! WE TRIED ARBITRATION TO GET RID OF OUR VEHICLE AND TOYOTA BASICALLY SAID THAT WE WERE LYING ABOUT THE PROBLEM. PLEASE REVIEW AND RECALL. I KNOW BY READING THE OTHER COMPLAINTS THAT I AM NOT THE ONLY ONE HAVING THIS ISSUE. THIS IS A SAFETY HAZARD!!! *TR

ALL BRAKE ROTORS HAD A CRACK PERPENDICULAR TO THE ROTATION. *TR

MY 2010 TOYOTA PRIUS CONTINUES TO EXPERIENCE THE MOMENTARY LOSS OF BRAKING POWER EVEN AFTER THE RECALL FIX WAS APPLIED BACK IN MARCH. I EXPERIENCE THE SAME LOSS OF BRAKING POWER AS I DID IN THE PAST WHEN GOING OVER BUMPS, POT HOLES AND THE LIKE, ESPECIALLY WHEN HITTING THE BRAKE ON A DECLINE. I BROUGHT MY CAR BACK TO THE DEALERSHIP AND A FIELD TECH SPECIALIST WAS UNABLE TO REPRODUCE THE PROBLEM - BUT I HAVE EXPERIENCED IT A HALF DOZEN TIMES SINCE THE RECALL AND HAVE NOTIFIED TOYOTA'S HQ - THEY HAVE NOT RESPONDED. I CONTINUE TO FEEL AS IF PEDESTRIAN, OTHER DRIVER, AND MY OWN SAFETY ARE AT RISK WITH THIS CONTINUED BRAKE ISSUE THAT TOYOTA CANNOT SEEM TO FIX. *TR

OUR NEW 2010 TOYOTA PRIUS LOST ITS BRAKES FOR A SHORT PERIOD WHEN DRIVING DOWN A STEEP HILL AT SLOW SPEED (10 MPH). ALTHOUGH I WAS PRESSING ON THE BRAKE PEDAL THE BRAKES COMPLETELY RELEASED FOR ROUGHLY 2 SECONDS AND THEN RE-APPLIED. WE HAD JUST DRIVEN OVER A SMALL BUT SHARP BUMP. I UNDERSTAND HOW ABS WORKS, AND THIS WAS NOT ABS. THE BRAKES COMPLETELY RELEASED AND THE CAR "JUMPED" FORWARD - IT JUMPED BECAUSE THE HILL WAS QUITE STEEP. WHAT IS MOST DISTURBING IS THAT THE CAR HAD JUST BEEN SERVICED (MAY 29TH) AND THE EVENT HAPPENED MAY 31. WHEN I CALLED THE DEALERSHIP THEY SAID THE CAR HAD BEEN RECALLED FOR A BRAKE PROBLEM BUT THEY HAD "FORGOTTEN" TO DO THE RECALL. FURTHER, I HAVE OWNED THE CAR FOR FIVE MONTHS AND HAVE NOT RECEIVED A RECALL NOTICE FROM TOYOTA. *TR

I HAVE A 2010 TOYOTA PRIUS PURCHASED IN JULY 2009. DURING OWNERSHIP I EXPERIENCED WHEN THERE WAS A CREASE, HOLE OR BUMP IN THE ROAD WHEN BRAKING - IT ACCELERATING AND LUNGES. I AVOIDED SITUATIONS LIKE THAT AND WHEN THE RECALL CAME, I TOOK IT TO BUTLER TOYOTA (ALSO HAD THE FLOOR MAT HOOKS INSTALLED PRIOR), ON APRIL 5, 2010. THEY SUPPOSEDLY FIXED IT. ABOUT A WEEK LATER, I CAME UPON A MANHOLE COVER IN A ROAD WHILE BRAKING AND MAKING A TURN SO GOING SLOW, AND THE SAME THING HAPPENED. THE NEXT DAY I PURPOSELY WENT THROUGH IT TO "TEST" AND IT DID THE SAME THING BUT LUNGE INTO THE OTHER LANE. I WAS SCARED AND CALLED BUTLER TOYOTA. THEY TOLD ME TO CALL NATIONAL TOYOTA TO REPORT. THEY CONTACT BUTLER AND I WENT BACK IN MAY 21, THEY DID NOT REPAIR IT AND "SHRUGGED" THEIR SHOULDERS SAYING IT'S THE ABS. THEY OFFERED TO HAVE A FIELD TECH PERSON COME DRIVE MY CAR. I CALLED NATIONAL AGAIN AND THEY SEEM TO BE "MEDIATING" THIS WITH BUTLER. I FOUND A REPORT FROM CONSUMERAFFAIRS.COM THAT THIS VERY SIMILAR ISSUE WAS OCCURRING BACK IN 2008 AND THEY CALLED IT "TRACTION CONTROL". NO ONE FROM TOYOTA HAS TOLD ME THIS. I WANT IT FIXED OR A DIFFERENT CAR. I HAVE A TEENAGE WITH A PERMIT AND IF HE WAS DRIVING THIS AND IT OCCURRED, HE WOULD PROBABLY RUN INTO SOMEONE BECAUSE IT TAKES YOU BY SURPRISE. I DO FEAR HIM DRIVING IT DUE TO HIS INEXPERIENCE AND I FRANKLY AM CONCERNED AND AM VERY CAUTIOUS AS A RESULT. *TR

I HAD THE TOYOTA PRIUS REFLASH DONE ON MY CAR. SINCE THIS REFLASH I HAVE HAD MULTIPLE INSTANCES OF THE BRAKE SURGE. THE MOST RECENT INCIDENT WAS YESTERDAY. I WAS DRIVING DOWN A ROAD GOING ABOUT 25 MPH. I NOTICED AN UPCOMING STOP SIGN AND A SMALL DIP IN THE ROAD. I ENGAGED THE BRAKES AND SLOWED TO ABOUT 10 MPH. UPON HITTING THE DIP THE CAR SURGED FORWARD TOWARD THE STOP SIGN AND INTERSECTION. DESPITE APPLYING EVEN AND STEADY PRESSURE TO THE BRAKE, THE CAR SUDDENLY SURGED FORWARD ON ITS OWN ACCORD. WE HAVE HAD MULTIPLE INSTANCES SINCE THE 'FIX' BY TOYOTA. WE TRIED ARBITRATION TO RESOLVE THE ISSUE, BUT WE HAVE BEEN IGNORED. I AM CONCERNED THAT A FUTURE SURGE WILL INEVITABLY LEAD TO AN ACCIDENT. THIS IS A DEFINITE SAFETY CONCERN THAT MUST BE ADDRESSED! *TR

BRAKE FAILURE OCCURRED WHEN VEHICLE WAS COMING OFF FREEWAY EXIT RAMP AT APPROXIMATELY 40 MPH ON UNEVEN, CURVY ROAD. WHILE APPROACHING INTERSECTION FROM SEVERAL HUNDRED FEET AWAY, BRAKES FAILED TO ENGAGE FOR ABOUT A SECOND; ALSO FELT THE VEHICLE "LURCH" FORWARD IN THAT LAPSE OF TIME. REPEATED PRESSURE ON THE BRAKES FINALLY BROUGHT CAR TO STOP BUT NOT IN TIME TO PREVENT COLLISION WITH INCOMING PICKUP TRUCK ON STRAIGHTAWAY TRAFFIC. POLICE ARRIVED AT SCENE BUT DID NOT FILE REPORT BECAUSE NOBODY WAS INJURED. BODY SHOP ESTIMATED DAMAGE ON FRONT BUMPER AT $1500. VEHICLE WAS BROUGHT IN TO DEALER ON 05/18/2010 FOR INSPECTION. SERVICE MANAGER SAID ECU BRAKE RECALL HAD BEEN CONDUCTED ON SAID VEHICLE IN FEBRUARY 2010 AT DIFFERENT DEALERSHIP. CURRENTLY STILL AWAITING ON CONCLUSIVE REPORT FROM TOYOTA ENGINEERS. CAR ONLY HAS 1000 MILES ON ODOMETER. BRAKE FAILURE HAS BEEN EXPERIENCED SOME TEN TIMES IN THE 2 MONTHS OF OWNING THIS VEHICLE, USUALLY DURING HIGHER SPEEDS OVER UNEVEN ROAD. CAME CLOSE TO ACCIDENTS ON THREE INSTANCES, NOT INCLUDING THIS ACTUAL ONE. THIS IS A SERIOUS SAFETY DEFECT THAT COULD RESULT IN FATALITIES. PLEASE INVESTIGATE! *TR

AS NOTED IN NHTSA INVESTIGATION PE10006. I ENTERED AN INCIDENT DATE OF 5/19/2010, BUT THIS HAPPENS CONSISTENTLY WITH MY 2010 TOYOTA PRIUS (PURCHASED OCT. 2009). IT IS AS DESCRIBED IN THE INVESTIGATION SUMMARY; A MOMENTARY LAPSE IN BRAKING WHILE TRAVELING OVER UNEVEN OR ROUGH SURFACES. I HAD THE SOFTWARE UPDATE PERFORMED LAST WEEK AND INTERESTINGLY, IT SEEMS TO HAVE GOTTEN WORSE SINCE THEN. IT'S VERY DISCONCERTING AND ALARMING. FORTUNATELY, IT'S NEVER HAPPENED WHEN THERE IS A CAR IN FRONT OF ME (AS ON THE EXIT RAMP OF A FREEWAY OR PRIOR TO A STOPLIGHT), BUT IF IT DOES, I HAVE NO DOUBT THAT IT WILL RESULT IN A CRASH, FOR WHICH I WILL NO DOUBT BE WRONGLY BLAMED AND CITED. I'M TO THE POINT THAT I WOULD PREFER THAT MY WIFE NOT DRIVE THE CAR AND AM CONSIDERING WHAT ACTION I CAN TAKE WITH TOYOTA --- RETURNING THE CAR, SOME KIND OF FINANCIAL COMPENSATION ETC. WHEN I HAD THE SOFTWARE UPDATE PERFORMED, I NOTED THE PROBLEM TO THE DEALERSHIP AND MADE THEM WRITE IT ON THE SERVICE ORDER TO DOCUMENT IT. THIS COMPLAINT IS ALSO TO DOCUMENT THE PROBLEM. I SHOULD NOTE THAT WE OWN A 1996 4RUNNER AND A 2003 HIGHLANDER (MY PARENTS OWN A 2010 PRIUS AND 2010 CAMRY AS WELL), SO IT'S NOT LIKE I HAVE SOMETHING AGAINST TOYOTA. ALSO, I TRAVEL A LOT FOR MY JOB (80%+) AND OVER THE LAST 6 MONTHS HAVE PROBABLY DRIVEN AT LEAST 20 DIFFERENT MAKES AND MODELS OF CARS. THIS HAS NEVER HAPPENED IN ANY CAR I HAVE OWNED OR RENTED. *TR

TWO ISSUES WITHIN 5 MINUTES (WILL FILE TWO REPORTS). FIRST ISSUE OCCURRED WHILE BACKING OUT OF LEVEL PARKING SPACE. BRAKES GRABBED ON AND OFF AS IF I WERE PRESSING BRAKES FIRMLY, RELEASING, THEN PRESSING FIRMLY AGAIN, EVEN THOUGH I WAS LIGHTLY HOLDING THE BRAKES AS I WAS REVERSING. SECOND ISSUE OCCURRED A FEW MINUTES LATER WHILE BRAKING ON A DESCENT, GOING APPROXIMATELY 35-40 MPH. MY FRONT LEFT TIRE WENT OVER A MANHOLE COVER WHICH CAUSED A MILD BUMP, WHICH RESULTED IN A MOMENTARY RELEASE OF THE BRAKES. CAR WAS PURCHASED NEW LAST WEEK (MAY 13, 2010), HAS APPROXIMATELY 400 MILES, AND HAS NO RECALLS OUTSTANDING. *TR

REGENERATIVE BRAKING - LOSS OF BRAKING, WHEN SLOWING OVER ROUGH ROAD SURFACE APPROXIMATELY 5-9MPH. BRAKES "GO AWAY", RESULTING IN FURTHER PEDAL APPLICATION TO AVOID STRIKING VEHICLE AHEAD. INCIDENT OCCURS SPORADICALLY, HOWEVER HAS OCCURRED AT LEAST 8 TIMES IN THE TWO MONTHS WE'VE OWNED VEHICLE. *TR

AFTER TAKING MY 2010 PRIUS IN FOR THE RECALL FIX ON APRIL 1, 2010, THE VEHICLE CONTINUED TO EXHIBIT SAFETY DEFECTS. I REPORTED THIS TO THE DEALER WHO REPORTED IT TO CORPORATE AND ARRANGED FOR A FIELD TECH TO ANALYZE THE VEHICLE ON APRIL 13TH. THEY SAID WE WOULD HEAR FROM TOYOTA WITH IN TWO WEEKS I NEVER HEARD BACK FROM THE DEALER SO I CALLED THE DEALER LAST WEEK. DEALER HAD NOT HEARD BACK. I FILED UNDER THE LEMON LAW. THEN DEALER INFORMED ME YESTERDAY 5/17 THAT THE CAR WAS HEALTHY AND THERE IS NOTHING MORE THEY CAN DO. MY CAR EXPERIENCED THE SAME BRAKE FAILURE THIS MORNING, TURNING INTO A PARKING LOT. *TR

2010 TOYOTA PRIUS. CONSUMER STATES VEHICLE DID NOT SEEM TO STOP IMMEDIATELY WHEN HE HIT A BUMP. *TGW

I HAVE A 2010 TOYOTA PRIUS, AND HAVE NOTICED THAT WHILE BRAKING ON UNEVEN PAVEMENT, THE CAR LURCHES FORWARD. THE JACK SAFRO DEALERSHIP SAID TO BRING IT IN, AS THERE WAS A RECALL. SINCE THEY WORKED ON IT, I SEE NO CHANGE. I CALLED THE DEALERSHIP AND TOLD THEM THERE WAS NO DIFFERENCE, AND THEY TOOK IT FOR A TEST DRIVE. THE MECHANIC SAID HE DIDN'T EXPERIENCE ANY PROBLEM. THEY SAID THEY WOULD NOTE THE PROBLEM, BUT THERE WAS NOTHING ELSE THEY COULD DO. I HAVE TO BE VERY CAREFUL WHEN APPROACHING A STOP SIGN OR LIGHT ON UNEVEN PAVEMENT. I FEAR REAR ENDING SOMEONE. OR WORSE HITTING A PEDESTRIAN. *TR

WHILE DRIVING ON BOWMAN ROAD IN WEST LITTLE ROCK, I WAS BRAKING AS I APPROACHED THE INTERSECTION AT MARKHAM. THE CAR SUDDENLY FELT LIKE IT WAS SURGING FORWARD AND NOT BRAKING AT ALL AS I DROVE OVER A MAN-HOLE COVER. THIS WAS ESPECIALLY PRONOUNCED AS I WAS GOING DOWNHILL AND TURNING TO THE RIGHT AT THE YIELD SIGN. MY WIFE NOTICED IT FROM THE PASSENGER SEAT AS WELL. WE MOMENTARILY FELT AS IF WE WOULD NOT STOP AND END UP IN THE PATH OF ONCOMING TRAFFIC. THIS HAPPENED AFTER THIS VEHICLE HAS ALREADY BEEN RECALLED FOR THIS SAME PROBLEM. UNFORTUNATELY, THE SOFTWARE UPGRADE DID NOT FIX THIS DANGEROUS PROBLEM. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT RECEIVED A RECALL NOTICE FOR RECALL 10V039000 (SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE) WHICH WAS PERFORMED. HOWEVER, THE CONTACT STATED THAT THE PROBLEM STILL OCCURRED AND WHENEVER SHE DROVE OVER A BUMP IN THE ROAD OR AN UNEVEN SURFACE AND DEPRESSED THE BRAKE PEDAL, THERE WAS A LOSS OF BRAKING AND THE VEHICLE WOULD LURCH FORWARD. THE VEHICLE HAD NOT BEEN TAKEN BACK TO THE DEALERSHIP AT THE TIME OF THE COMPLAINT. THE FAILURE MILEAGE WAS APPROXIMATELY 7,500. THE CURRENT MILEAGE WAS APPROXIMATELY 10,000.

I HAVE A 2010 TOYOTA PRIUS AND I RECEIVED THE SOFTWARE RECALL FOR THE BRAKING SYSTEM. AFTER RECEIVING THE SOFTWARE RECALL MY WIFE AND I HAVE BOTH NOTICED THAT THERE ARE INSTANCES WHEN THE BRAKES DO NOT RESPOND AS QUICKLY AS THEY SHOULD WHICH IS SIMILAR TO THE ORIGINAL REASON THE PRIUS WAS RECALLED. *TR

I HAVE A 2010 PRIUS AND I HAVE THE BRAKING PROBLEM THAT WAS RECALLED FOR A SOFTWARE UPDATE. I HAD THE SOFTWARE UPDATE PERFORMED AND I STILL HAVE A LOSS OF BRAKING CONTROL WHEN I GO OVER A BUMP IN THE ROAD. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE DRIVING AT SPEEDS OF 15 MPH AND ATTEMPTING TO BRAKE, THE ANTI LOCK BRAKING SYSTEM FAILED AND THE BRAKES WOULD NOT ENGAGE. THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE AND ADVISED THE CONTACT THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. PREVIOUSLY, THE CONTACT RECEIVED REPAIRS TO THE SERVICE BRAKES AND ELECTRONIC CONTROL MODULE UNDER AN UNKNOWN RECALL AND STATED THE FAILURE WAS NOT THE FIRST OCCURRENCE FOLLOWING RECALL REPAIRS. THE FAILURE MILEAGE WAS 11,100 AND THE CURRENT WAS 11,500.

I CONTINUE TO HAVE A LOSS OF BRAKING WHEN TRAVELING OVER BUMPY SURFACES, EVEN AFTER RECEIVING THE SOFTWARE UPGRADE THAT WAS RELEASED BY TOYOTA. THIS IS ESPECIALLY TROUBLING WHEN I AM TRAVELING OVER AN EXTENDED AREA OF BUMPY ROAD, AND THE BRAKES WON'T WORK AS EXPECTED. *TR

2010 TOYOTA PRIUS. VEHICLE REPAIR WAS COVERED UNDER A RECALL, BUT AFTER A NO BRAKE INCIDENT CONSUMER QUESTIONS THE REPAIR. *GR THE CONSUMER STATED THE RECALL WAS PERFORMED ON APRIL 3, 2010. HOWEVER, ON APRIL 6, 2010 HE HIT A SLIGHT BUMP AS HE APPLIED THE BRAKES AND HAD A MOMENTARY FEELING OF HAVING NO BRAKES. THE VEHICLE DID STOP. HOWEVER, THE INSTANCE DID LEAD THE CONSUMER TO QUESTION THE ADEQUACY OF THE FIX. *JB

I HAVE A 2010 TOYOTA PRIUS WITH BRAKING PROBLEMS, WHICH HAVE CONTINUED TO OCCUR EVEN AFTER I TOOK IT TO MY TOYOTA DEALER FOR THE RECALL REPAIR ON FEBRUARY 12, 2010. THREE TIMES SINCE THEN THE BRAKES DID NOT ENGAGE FOR ABOUT THREE SECONDS, WHEN I WAS TRYING TO STOP, ON A DRY SURFACE THAT WAS SLIGHTLY UNEVEN. THIS WAS NOT THE SUDDEN RAPID PUMPING OF ABS BRAKES WHICH I WOULD RECOGNIZE FROM YEARS OF USE WITH ABS EQUIPPED CARS. THE DEALER SAW NO PROBLEM WHEN I BROUGHT IT BACK TO THEM LAST WEEK. I AM WORRIED IT WILL CAUSE AN ACCIDENT. *TR

2/13, THE DAY AFTER MY CAR WAS "FIXED" UNDER THE RECALL, MY BRAKES FAILED. I WAS ON THE WAY TO THE AIRPORT, AND THE BRAKES FAILED . WHEN I RETURNED HOME FROM MY TRIP, I BROUGHT IT IN TO TOYOTA KEARNY MESA IN SAN DIEGO, WHO FOUND NOTHING WRONG. MY BRAKES FAILED AGAIN A WEEK AGO. I WAS DRIVING ON A SMOOTH ROAD, SLOWING DOWN FOR A LIGHT, WHEN SUDDENLY THE CAR SPEEDED UP AND I WENT STRAIGHT THOUGH THE RED LIGHT. NO CARS WERE NEARBY, SO I DID NOT CRASH AND NO ONE WAS HURT. AGAIN, TOYOTA FOUND NOTHING WRONG. THEY TELL ME THAT THEY CAN'T FIX IT UNLESS THEY CAN "REPLICATE" THE PROBLEM. THEY WANT ME TO RETURN THE LOANER CAR TOMORROW MORNING AND DRIVE HOME WITH MY PRIUS AND I'M SCARED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT SPEEDS OF 5 MPH OVER A POTHOLE WITH THE BRAKES APPLIED, THE VEHICLE DID NOT STOP. THE DEALER WAS CONTACTED BUT DID NOT PROVIDE ANY ASSISTANCE. THE VEHICLE WAS NOT REPAIRED OR DIAGNOSED. THE FAILURE AND CURRENT MILEAGES WERE 5,800. UPDATED 08/13/10. *LJ UPDATED 08/23/10*JB

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO THE DEALER FOR REPAIRS UNDER NHTSA RECALL CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). SINCE THE VEHICLE WAS REPAIRED THE BRAKE PEDAL WOULD FALL ONTO THE FLOORBOARD WHEN THE BRAKES WERE APPLIED. THERE WAS A HESITATION IN BRAKE ENGAGEMENT AND THE CONTACT HAD TO USE THE EMERGENCY BRAKES IN ORDER TO STOP THE VEHICLE. THE MANUFACTURER WAS CONTACTED BUT WOULD NOT PROVIDE ANY FURTHER ASSISTANCE. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 9,000 AND THE CURRENT MILEAGE WAS 12,000.

IN MY 2010 PRIUS I HAVE HAD TWO INCIDENCE WITH MY BRAKE WHEN STARTING OUT IN REVERSE. FIRST TIME WAS IN MY DRIVEWAY, DON'T REMEMBER HOW LONG I WAS IN THE CAR UNTIL MY GIRLFRIEND GOT IN.. BUT WHEN I PUT IT INTO REVERSE I GOT A"STIFF" FEELING IN THE PEDAL AND IT FELT LIKE IT WOULDN'T GO DOWN ALL THE WAY... THE CAR SEEMED TO ACCELERATE BACK FASTER THAN EXPECTED WHEN I LIFTED MY FOOT OFF THE BRAKE.... I LIFTED MY FOOT AND PUT THE BRAKE DOWN AND I STOPPED VERY QUICKLY (AS IF I WAS SLAMMING ON THE BRAKES) I THEN TOOK MY FOOT OFF AND REAPPLIED A FEW TIMES AND THE PEDAL FELT FINE. WE THEN DROVE TO THE LOCAL MARKET.. I SAT IN THE CAR WITH THE ACC MODE ON FOR ABOUT 5-8 MINUTES WHILE SHE WENT IN... WHEN SHE CAME OUT I STARTED THE CAR, WENT TO BACK UP AND THE SAME THING HAPPENED.... THIS WAS VERY DISCONCERTING IN A CROWDED LOT WITH LOTS OF PEOPLE WALKING IN CLOSE PROXIMITY TO THE CARS.... I BELIEVE I JUST HIT THE PARK BUTTON... THEN REAPPLIED THE BRAKE (WHICH NOW FELT NORMAL) AND I HAVEN'T HAD THE ISSUE SINCE.... THIS ISSUE HAS BEEN DISCUSSED IN PRIUS FORUMS AT LENGTH AND THERE IS A VERY CONSISTENT THEME TO THE INCIDENTS THAT TOYOTA SHOULD EXPLORE AND DEAL WITH. *TR

2010 TOYOTA PRIUS. THE CONSUMER STATED HE EXPERIENCED TWO SAFETY ISSUES; LOSS OF BRAKE EFFECTIVENESS AND ENGINE RACE *TGW WHEN THE CONSUMER APPLIED THE BRAKES WHEN GOING OVER BUMPS/ROUGH ROADS, OR IN MARGINAL CONDITIONS DUE TO SNOW/ICE WHEN APPROACHING A STOP SIGN, HE WOULD LOSE BRAKING EFFECTIVENESS. THE CONSUMER TOOK THE VEHICLE TO THE DEALER FOR A RECALL REPAIR ON MARCH 24, 2010. HOWEVER, HE CONTINUED TO EXPERIENCE LOSS OF BRAKE EFFECTIVENESS. THE CONSUMER PULLED INTO A NEIGHBOR'S DRIVEWAY AFTER DRIVING LESS THAN ONE MILE FROM HIS HOME. AFTER PUSHING THE PARK BUTTON, BUT BEFORE PUSHING THE POWER BUTTON, THE ENGINE BEGAN TO RACE. IT WAS NOT AT AN EXTREME HIGH RPM AND IT WAS NOT FOR AN EXTENDED PERIOD TIME, BUT IT DID LAST FOR SEVERAL SECONDS. AFTER THE VEHICLE WENT DOWN TO NORMAL RPM, AFTER A S SECOND OR TWO, IT BEGAN ALL OVER AGAIN. THE CONSUMER STATED IT WAS NOT A SURGE AS THE VEHICLE WAS NOT IN GEAR AT THE TIME. *JB

TOYOTA 2010 PRIUS BRAKE RECALL PATCH WAS ONLY PARTLY EFFECTIVE. IN THE WINTER THE CAR COULD LOOSE BRAKING FOR 6 TO 8 FEET AFTER HITTING A ROUGH SPOT, POT HOLE ETC. NOW IT SKIPS MAYBE 2 TO 3 FEET. THE DEALER AND TOYOTA FACTORY PEOPLE TELL ME IT'S NORMAL ANTI-LOCK BRAKE ACTION. I SAY I HAVE DRIVEN MANY CARS WITH ANTI-LOCK BRAKES AND THEY TO NOT LOOSE BRAKE ACTION, THEY PULSE THE BRAKES. THE TOYOTA FACTORY PEOPLE TELL ME THE CAR IS STILL BRAKING EVEN IF IT FEELS LIKE IT ISN'T. I DO NOT AGREE WITH THAT FOR A SECOND. THE DEALER WANTS TO TEST DRIVE THE CAR TO DETERMINE CONDITION. HOWEVER IT ONLY HAPPENS MAYBE ONCE A WEEK AND NOT AT EVERY BUMP OR JOLT OF THE SUSPENSION. I FEEL TOYOTA DOES NOT HAVE A PROPER FIX AND IS NOT WORKING ON ONE. THEY ARE TRYING TO TALK US PRIUS OWNERS INTO ACCEPTING THIS FLAW AS NORMAL FOR THE CAR. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 40 MPH ON WET ROAD CONDITIONS AND ENCOUNTERED A POTHOLE. THE BRAKES WERE ENGAGED WITH A DELAY RESPONSE PERIOD BETWEEN 5 TO 10 SECONDS. THE VEHICLE WAS ABLE TO SLOW DOWN AND CONTINUED TO TRAVEL. THE VEHICLE HAD A PRIOR RECALL REPAIR ON MARCH 1, 2010 UNDER THE NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE REMEDY REPAIR WAS INSUFFICIENT AND FAILED TO CORRECT THE PROBLEM. THE MANUFACTURER WAS NOTIFIED OF THE MALFUNCTION. THE CONTACT WAS WAITING FOR A RESPONSE FROM THE MANUFACTURER FOR RESOLUTION. THE FAILURE AND CURRENT MILEAGES WERE 4,860.

I RECEIVED DELIVERY OF MY NEWLY PURCHASED 2010 PRIUS ON 10/17/09. THE BRAKES LOCKED UP ON SEVERAL OCCASIONS DURING NOV AND DEC 2009, ON ROUGH ROADS AND DURING SLIPPERY CONDITIONS. I HAD THE BRAKES CHECKED 1/2/10 BY THE TOYOTA DEALER; THEY WERE UNABLE TO DUPLICATE THE CONDITIONS. ON APPROXIMATELY 2/4/10, THE BRAKES FAILED DURING AN ICE STORM AND THE CAR ENDED UP ON SOMEONE'S FRONT LAWN. THERE WERE NO INJURIES OR PROPERTY DAMAGE, THUS THE INCIDENT WAS NOT REPORTED. FOLLOWING THIS INCIDENT, I TOOK THE CAR TO THE TOYOTA DEALER FOR INSPECTION AND RECEIVED A LOANER CAR. WHILE THE DEALER HAD MY CAR, TOYOTA ISSUED A RECALL FOR THE PRIUS' BRAKES. THE BRAKES ON MY PRIUS WERE REPROGRAMMED 2/9/10. SINCE THEN I HAVE HAD FOUR INSTANCES WHERE THE BRAKES LOCKED UP, THE LATEST OF WHICH WAS 4/21/10. THE CAR IS CURRENTLY AT THE TOYOTA DEALER BEING INSPECTED. THE CAR WAS PURCHASED AT COLONIAL TOYOTA IN MILFORD AND ALL SUBSEQUENT SERVICE HAS BEEN PERFORMED BY THAT DEALER. *TR

I HAVE A TOYOTA PRIUS AND IT HAS BEEN RECALLED ABOUT THE BRAKES. I SENT IT IN TO HAVE THE BRAKES FIXED, BUT I AM STILL HAVING PROBLEMS. WHEN EVER I START TO STOP THE CAR AND THERE ARE BUMPS IN THE ROAD THE CAR SEEMS TO ACCELERATE OR THE BRAKES RELEASE. IT ONLY HAPPENS IF THERE IS BUMPS IN THE ROAD. THE CAR WILL NOT STOP WHEN IT HITS THE BUMPS. WHAT SHOULD I DO? *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 25 MPH ON A ROUGH ROAD SURFACE AND OVER A POTHOLE. WHEN THE BRAKE PEDAL WAS APPLIED, THE VEHICLE SURGED FORWARD WITH NO POWER RESPONSE. THE VEHICLE WAS TAKEN TO THE DEALER FOR A RECALL SOFTWARE REPAIR. THE NHTSA CAMPAIGN ID NUMBER WAS UNKNOWN. THE CONTACT WAS UNCERTAIN OF THE RECALL REMEDY. THE FAILURE CONTINUED TO OCCUR AFTER THE RECALL REPAIR WAS PERFORMED. THE BRAKES WERE ENGAGED FOUR TO FIVE TIMES WITHOUT A RESPONSE. THE CONTACT WAS EXPECTING A RESPONSE FROM THE MANUFACTURER WITHIN THE NEXT TWO DAYS. THE FAILURE MILEAGE WAS 11,000.

BRAKING ISSUE - 2010 TOYOTA PRIUS. WE PURCHASED A 2010 PRIUS LAST WEEK, ASKED THE DEALERSHIP IF ANY/ALL RECALL WORK HAD BEEN COMPLETED AND WERE TOLD 'YES.' YET, I BELIEVE THAT THE DEALERSHIP MISREPRESENTED THE FACTS - BOTH MY HUSBAND AND I HAVE EXPERIENCED TEMPORARY LOSS OF BRAKING IN OUR NEW 2010 PRIUS WHILE GOING OVER ROUGH PATCHES IN THE ROAD AND OVER SPEED BUMPS/TRAFFIC CALMING BUMPS. WE BOTH DOUBT THAT THE ABS RECALL WORK WAS ACTUALLY DONE BEFORE WE TOOK POSSESSION OF THE CAR LAST WEEK, SO WE'RE TAKING IT BACK TO THE DEALERSHIP TODAY. I AM NOT AFRAID TO BUY A TOYOTA AND UNDERSTAND THAT OTHER CAR MANUFACTURERS HAVE EXPERIENCED QUALITY ISSUES RESULTING IN RECALLS, BUT I AM VERY UPSET THAT WE ASKED ABOUT THE RECALL WORK AND STILL ENDED UP WITH A CAR WITH BRAKING ISSUES. I DON'T WANT TO DRIVE A POTENTIALLY UNSAFE VEHICLE. *TR

I OWN A 2010 PRIUS. I RECEIVED A RECALL NOTICE AND TOOK IT IN TO THE DEALER FOR REPAIR. NEVERTHELESS, EVEN AFTER THE ALLEGED REPAIR, PROBLEMS STILL HAPPEN WHILE BRAKING. SPECIFICALLY, IF I HIT A BUMP OR A POTHOLE WHILE BRAKING, THE CAR SURGES FORWARD. I WOULD SAY THIS HAPPENS TO ME MULTIPLE TIMES PER WEEK. *TR

2010 TOYOTA PRIUS "SURGE" WHILE BRAKING OVER BUMPY ROAD SURFACE...I BROUGHT MY CAR IN FOR THE RECALL MOD AND THE PROBLEM SEEMS WORSE THAN EVER!! WHAT GIVES?? *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED HE PREVIOUSLY RECEIVED REPAIRS UNDER NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). PRIOR TO THE RECALL, THE CONTACT HAD EXPERIENCED A DELAY IN BRAKE RESPONSE WHEN TRAVELING OVER ROUGH ROAD SURFACES. FOLLOWING REPAIRS, THE FAILURE PERSISTED BUT WOULD OCCUR ON VARIOUS ROAD SURFACES, INCLUDING FLAT AND DRY SURFACES. THE FAILURE MILEAGE WAS 6,800 AND THE CURRENT MILEAGE WAS 7,300. THE VIN WAS NOT AVAILABLE. UPDATED 06/29/10 *BF

2010 TOYOTA PRIUS III. THE CONSUMERS DAUGHTER WAS INVOLVED IN AN ACCIDENT. THE BRAKES DID NOT STOP THE VEHICLE WHEN THEY WERE APPLIED. SHE COLLIDED WITH THE VEHICLE IN FRONT OF HER, WHICH THEN HIT ANOTHER VEHICLE. *JB

1. BRAKES DISENGAGED ON TWO SEPARATE OCCASIONS WHILE BRAKING TO A RED LIGHT AND WENT OVER UNEVEN PAVEMENT. 2. CAR IS PARKED IN GARAGE. IN THE MORNING I WENT TO START THE CAR AND UPON PUSHING THE START BUTTON THE CAR STARTED VIOLATING SHAKING AND MAKING A CLANKING NOISE. I IMMEDIATELY TURNED CAR OFF AS THIS WAS NOT A NORMAL OCCURRENCE. I PUSHED THE START BUTTON AGAIN AND CAR STARTED NORMALLY. 3. ON 4/1/10 TOOK CAR TO TOYOTA OF ORANGE FOR RECALL FIX OF THE BRAKES. ON 4/2 WHILE PULLING UP TO A STREET FROM A PARKING LOT THE BRAKES DISENGAGED. THE ASPHALT WAS VERY BUMPY IN THE PARKING LOT. I WAS ON A SLIGHT DECLINE. THE BRAKES DISENGAGED AND CAR LURCHED FORWARD. IT WAS WORSE THAN THE OTHER TWO TIMES. IT WAS SCARY. IF THERE WAS A CAR IN FRONT OF ME I WOULD HAVE HIT THEM. *TR

THE VEHICLE WAS PARKED AND WAS STARTED. THE VEHICLE WAS PUT INTO REVERSE AND THE CAR THEN JUST LURCHED FOR A MOMENT. I JAMMED ON THE BRAKES AND THE BRAKE PEDAL BECAME VERY HARD AND CAME ALL THE WAY TO THE TOP . I HELD THE BRAKE AND THEN JUST SHUT THE CAR OFF. UPON RESTART THE VEHICLE WAS OK. IT DID NOT REPLICATE THE PROBLEM AGAIN. THIS IS THE 4TH OR 5TH TIME THIS HAS HAPPENED AND IT IS ALWAYS THE SAME. THE CAR IS PARKED AND I HAVE TO PUT IT IN REVERSE. *TR

I HAVE THE 2010 PRIUS AND HAD THE BRAKE RECALL WORK PERFORMED ON MY VEHICLE. IT DIDN'T WORK. WHEN I GO DOWN A HILL AND HIT A SPEED BUMP EVEN AT 5 MILES AN HOUR WHILE BRAKING THE CAR DOESN'T BRAKE FOR A FEW SECONDS. I MOVE 5-10 FEET UNCONTROLLED. IF THERE ARE CARS BACKED UP AT THE STOP I WOULD HIT THEM. *TR

I HAVE A 2010 TOYOTA PRIUS THAT WAS RECALLED AND REPAIRED IN MARCH 2010. ON APRIL 4, 2010 I WAS DRIVING THE CAR WITH MY WIFE AND WAS UNDER NORMAL BRAKING CONDITIONS WHEN I PRESSED THE BRAKES AND THEY ACTED LIKE THEY WERE ANTI-LOCK. THE PEDAL SKIPPED AND WENT TO THE FLOOR. IT WAS SO NOTICEABLE THAT MY WIFE ASKED WHAT JUST OCCURRED AND I TOLD HER THE BRAKES FAILED FOR A SECOND. I WAS AT ABOUT 20-30 MILES PER HOUR WHEN THIS OCCURRED COMING UP TO A STOP LIGHT. AGAIN THE CAR WAS TAKEN IN FOR THE RECALL PRIOR TO THIS. *TR

DESPITE HAVING HAD THE BRAKE RECALL ITEM FIXED ON MY 2010 TOYOTA PRIUS, I CONTINUE TO EXPERIENCE INSTANCES WHEN I DEPRESS THE BRAKE AND THE CAR SKIDS FROM SIDE TO SIDE WITH A SENSATION THAT THE END OF THE CAR IS LITERALLY LIFTING OFF THE GROUND. THIS HAS HAPPENED TO ME MULTIPLE TIMES AND TOYOTA HAS TOLD ME THAT THE RECALL FIXED ANY CONCERNS, SO THERE SHOULDN'T BE ANYTHING WRONG. ON ONE OCCASION WHEN THIS HAPPENED MY VEHICLE ACTUALLY BUMPED INTO A FIXED OBJECT, CAUSING DAMAGE TO THE FRONT BUMPER. I PURCHASED THIS CAR BASED ON TOYOTA'S REPUTATION AND AM NOW SO MISTRUSTING OF IT THAT I HESITATE TO PUT MY FAMILY IN IT. AS A CONSUMER I STRONGLY FEEL THAT I AND ALL OWNERS OF 2010 PRIUS' SHOULD HAVE THE RIGHT TO OPT TO RETURN OUR VEHICLES TO TOYOTA AND HAVE THE OPPORTUNITY TO SELECT A DIFFERENT NEW OR USED VEHICLE OF THE SAME PRICE FOR WHAT WE PAID FOR OUR CARS. THE PROVEN CONCERNS ABOUT THE 2010 PRIUS SHOULD BE ENOUGH FOR THE NHTSA TO PUT PRESSURE ON TOYOTA TO ALLOW FOR SOME TYPE OF RESTITUTION. IT IS NOT AS SIMPLE AS JUST TRADING IN THE CAR AT ANY RANDOM DEALER BECAUSE THE REPUTATION OF THESE CARS HAS SEVERELY LOWERED THE MARKET VALUE. TOYOTA'S ERRORS SHOULD NOT BE PERMITTED TO HAVE A FINANCIAL IMPACT ON THOSE CONSUMERS WHO PURCHASED THEIR CARS. I WOULD BE HAPPY TO ALLOW NHTSA TO TEST MY VEHICLE FOR A SHORT PERIOD OF TIME IF IT WOULD HELP IN THE RESEARCH OF THIS PROBLEM. *TR

ABS BRAKES FAIL TO ENGAGE WHEN ONE OF THE FRONT TIRES HITS POT HOLE / SLIPPERY BUMPY SURFACE. THE CAR SURGES FORWARD DURING BRAKING BEFORE BRAKING RESUMES. THE RECALL AND FIX TOYOTO IMPIMENTED ON MY CAR ON 2/15 DID NOT ADDRESS THE ISSUE, IT ONLY SHORTENED TO LAG TIME (PERIOD OF EXCELERATION - SURGE FORWARD). THE ISSUE STILL EXISTS AND IS STILL A DANGEROUS SAFETY HAZARD. I REPORTED THIS TO THE DEALER IN SMITHTOWN, NY WHO CONTACTED TOYOTA FACTORY AND THEY ADVISED THE DEALER, WHO ADVISED ME THAT THE CAR OPERATES AS PER SPECIFIATION. THE DEALER AND THE FACTORY DID NOT EVEN LOOK AT MY CAR! I DEMANDED A WORK ORDER WHICH THEY GAVE ME STATING "CAR TO BE BROUGHT BACK AFTER TOYOTA IS CONTACTED ADN ADVISES DEALER ON THE CONDITION". THE NEXT DAY THE DEALER CALLED ME TO SAY TOTOTA ADVISED THE CAR IS WORKING AS PER SPEC. TOYOTA REFUSES TO ADDRESS THIS ISSUE AND THE DEALER WILL NOT LOOK AT THE CAR. THIS IS A SAFETY HAZZARD THAT I SHOULD NOT HAVE TO BE SUBJECTED TO. PLEASE CONTACT ME. THANK YOU DOREEN GEBBIA, NESCONSET, NY

2010 TOYOTA PRIUS. CONSUMER STATES BRAKE PROBLEMS. *TGW THE CONSUMER STATED IT APPEARED AS IF THE SOFTWARE PATCH FOR THE 2010 PRIUS WAS NOT ENOUGH AS HE HAS EXPERIENCED ONE MORE OCCURRENCE SINCE GETTING THE PATCH ON MARCH 1, 2010. PRIOR TO THE SOFTWARE PATCH, THE CONSUMER EXPERIENCED BRAKE STUTTERING MAY BE 10 TIMES. THE CONSUMER STATED HE READ WHERE THE SWITCH FROM REGENERATIVE TO MECHANICAL BRAKING OCCURRED AT ABOUT 9 MPH HE NOTICED THAT THE BRAKE STUTTERING SEEMED TO OCCUR CLOSER TO 20 MPH. IT WOULD NOT JUST OCCUR WHEN HITTING A SMALL POTHOLE, BUT SOMETIMES WITH JUST STEADY BRAKING ON SMOOTH SURFACES. ON A SMOOTH SURFACE, THE FEELING WOULD BE A BIT OF A JERK. HE WOULD DECELERATE WITH PRESSURE AGAINST THE SEAT BELT AND HIS HANDS ON THE STEERING WHEEL, THEN THERE WOULD BE 1/4 OF A SECOND WHERE THERE WAS NO PRESSURE BECAUSE THE BRAKES WERE NOT WORKING, THEN HE WOULD JERK FORWARD AS THE BRAKES BEGAN TO WORK AGAIN, THERE WAS A SOMEWHAT DIFFERENT SENSATION WHEN HITTING A SMALL POTHOLE. THE MOST RECENT MOMENTARY BRAKE FAILURE OCCURRED WHILE STOPPING FOR A RED LIGHT. THE CONSUMER STATED HE SLOWED DOWN TO 20 MPH WHEN HE FELT A DIFFERENT TYPE OF STUTTERING THAN PREVIOUSLY. IT MAY HAVE BEEN A DOUBLE STUTTERING, BUT IT SEEMED HARDER. *JB

I HAVE A 2010 TOYOTA PRIUS AND HAD IT TAKEN BACK TO THE DEALERSHIP FOR THE RECENT RECALL. HOWEVER, I AM STILL EXPERIENCING THE SAME PROBLEMS AS BEFORE WITH THE CAR. WHENEVER I HAVE GONE OVER A BUMP THE CAR FEELS LIKE IT "JUMPS" FORWARD AND LOSES A LITTLE CONTROL.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 7 MPH ON A BUMPY ROAD SURFACE. WHEN THE BRAKES WERE ENGAGED THE VEHICLE SURGED FORWARD. WHENEVER TRAVELING BETWEEN 55 MPH ON BUMPY ROAD CONDITIONS THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER. THE TECHNICIAN WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE HAD PRIOR RECALL REMEDY ASSOCIATED WITH NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE FAILURE OCCURRED AFTER THE RECALL SERVICE REPAIR WAS PERFORMED ON THE VEHICLE. THE FAILURE MILEAGE WAS 11,000. THE CURRENT MILEAGE WAS 12,657.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 4 MPH WHEN THE BRAKES WERE APPLIED, THE ANTI-LOCK BRAKE SYSTEM WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL AND THE BRAKES BEGAN TO LOCK. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER. THE TECHNICIAN CONFIRMED THAT THE BRAKES WERE NOT OPERATING PROPERLY AFTER TEST DRIVING THE VEHICLE. THE VEHICLE REMAINED AT THE DEALER FOR FURTHER INSPECTION. THE CONTACT WAS PROVIDED A LOANER VEHICLE. THE TECHNICIAN STATED THAT AFTER THE FINAL INSPECTION THE BRAKES WERE OPERATING NORMALLY. THE FAILURE MILEAGE WAS 30. THE CURRENT MILEAGE WAS 5,500.

I PURCHASED MY 2010 PRIUS BACK IN JULY OF 2009 AND HAD PROBLEMS STOPPING THE CAR WHEN APPLYING THE BRAKE OVER A BUMP OR A POT HOLE ON THE ROAD. THE CAR WOULD ACCELERATE FOR A SECOND BEFORE COMING TO A FULL STOP. WHEN THERE WAS VOLUNTARY RECALL, FOR ME IT WAS MANDATORY BECAUSE THIS WAS A SERIOUS ISSUE BECAUSE IF THERE WOULD HAVE BEEN A CAR IN FRONT OF ME, OR IF THIS WAS CLOSE TO AN INTERSECTION AND PEDESTRIANS, WHO KNOWS WHAT COULD HAPPEN. I TOOK IT TO THE DEALERSHIP TO GET THE RECALL. THEY TOLD ME IT IS SOME SOFTWARE UPDATE. AFTER GETTING THE VEHICLE SERVICED, I TOOK IT FOR A TEST DRIVE AND NOTICED SLIGHT IMPROVEMENT IN THE RESPONSE WHEN APPLYING THE BRAKE PEDAL. BUT THIS MORNING AS I WAS APPLYING MY BRAKE HEADING TOWARDS THE INTERSECTION TO MAKE A TURN, I HIT A POT HOLE AND THE ACCELERATED AGAIN AND I HAD TO QUICKLY MANEUVER THE VEHICLE TO AVOID COLLISION WITH THE CAR IN FRONT OF ME. WHATEVER THEY DID WITH THE RECALL DID NOT RESOLVE THE BRAKE PROBLEMS.

2010 PRIUS STILL ACCELERATES AFTER "FIX".

2010 TOYOTA PRIUS. CONSUMER STATES REAR BRAKES RELEASED OR SLIPPED AND VEHICLE SPED UP. *TGW THE CONSUMER STATED WITHIN THE FIRST MONTH OF DRIVING, SHE DROVE OVER AN UNEVEN, PERHAPS POTHOLED AREA IN THE ROAD AND IT SEEMED AS IF THE VEHICLE'S REAR BRAKES RELEASED OR SLIPPED, AND THE VEHICLE SPED UP. THE VEHICLE THEN SEEMED TO CORRECT ITSELF AND DROVE SMOOTHLY AHEAD WITH PROPER BRAKING. *JB

THE BRAKE FIX ON MY 2010 TOYOTA PRIUS DID NOT SOLVE THE PROBLEM WITH THE BRAKES RELEASING UNDER CERTAIN CONDITIONS. I EXPERIENCED THE PROBLEM 3 TIMES BEFORE THE FIX AND 2 TIMES AFTER. THE ONLY WAY I COULD REPRODUCE THE PROBLEM WAS WHILE BRAKING ON A SNOW COVERED ROAD. SINCE HAVING MY CAR REPAIRED UNDER TOYOTA'S RECALL PROGRAM, I HAD THE BRAKES RELEASE ONCE ON WET ROADS (3/14) AND ONCE ON ICE (3/25).

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING THE VEHICLE AT A SPEED OF 25 MPH, THE VEHICLE CONTINUED TO ACCELERATE EVEN AFTER THE BRAKE PEDAL WAS APPLIED WHEN DRIVING ON A ROUGH OR BUMPY SURFACE. THIS INCIDENT OCCURRED ABOUT FORTY TIMES SINCE THE VEHICLE WAS PURCHASED. THE VEHICLE WAS TAKEN TO THE DEALERSHIP ON TWO OCCASIONS. ON THE SECOND VISIT TO THE DEALERSHIP, THE DEALER UPDATED THE COMPUTER SOFTWARE IN THE VEHICLE. HOWEVER, THE UPDATE DID NOT REMEDY THE PROBLEM. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 11,000.

RECALL ON TOYOTA PRIUS (2010), DID NOT RECEIVE RECALL NOTICE UNTIL AFTER RETURNED TO DEALER FOR RECALL, SERVICE PERFORMED, STILL HAS SAME ISSUE, RETURNED TO DEALER RON HIBBARD TOYOTA 3/23/10, MECHANIC STATED THEY HAVE DONE ALL THEY CAN DO, MILAGE, DATE, AND SPEED AT TIME OF INCIDENTS ARE APPROX. SAME ISSUE OCCURRED 2 TIMES SINCE RECALL SERVICE

2010 TOYOTA PRIUS. CONSUMER STATES BRAKE FAILURE IN WHICH THE MALFUNCTION HAPPENED TWICE AND CAUSED AN ACCIDENT. *TGW THE CONSUMER STATED THE FACTORY DEFECT WAS NOT BROUGHT TO LIGHT UNTIL AFTER THE SECOND INCIDENT. ALTHOUGH, TOYOTA CORRECTED THE BRAKE ISSUE, THE CONSUMER HAS COSTS AND OUTSTANDING PROBLEMS WITH THE VEHICLE BECAUSE OF THE DAMAGE DONE IN FIRST INCIDENT, INCLUDING PROBLEMS WITH THE WHEEL BEARING. THE CONSUMER IS REQUESTING TOYOTA REIMBURSE HIM FOR MONIES PAID TO FIX THE VEHICLE AND ALSO TO FIX THE WHEEL BEARING THAT WAS NOT IDENTIFIED AND NOT REPLACED. THE CONSUMER STATED THE FIRST INCIDENT HAPPENED WHEN HE WAS ABOUT TO MAKE A RIGHT TURN. THERE WAS SNOW ON THE ROADS AND AS HE WAS MAKING THE TURN, TRAVELING ABOUT 9 OR 10 MPH, HE STARTED SLIDING TOWARD THE CURB ON THE OTHER SIDE. HE TRIED TO BRAKE, BUT HE CONTINUED TO SLIDE. AN INSTANT BEFORE HE HIT THE CURB, THE ANTI-LOCK BRAKES ACTIVATED, BUT IT WAS TOO LATE. HE SLID INTO THE CURB WITH THE WHEEL TURNED, BROKE THE WHEEL RIM AND FLATTENED THE TIRE. THE SECOND FAILURE OCCURRED WHEN HE WAS COMING OUT OF A MALL PARKING LOT HEADING TOWARD A MAIN STREET. THE CONSUMER STATED HE WAS COASTING TO THE STOP SIGN AND APPLIED THE BRAKES, BUT NOTHING HAPPENED. HE PUSHED THEM AS HARD AS HE COULD AND AGAIN AT THE LAST SECOND THE ANTI-LOCK BRAKES ACTIVATED. *JB

ON 12/28/09 AT APROX. 6:30 A M, WHILE DRIVING MY 2010 TOYOTA PRIUS, I ATTEMPTED TO STOP ON A ROUGH ICE/SNOW PACKED SURFACE. I WAS TRAVELING AT ABOUT 5 MPH. THE VEHICLE SLID FOR ABOUT 20 TO 25 FEET BEFORE CRASHING INTO A SNOW BANK. THE ABS DID NOT OPERATE, AS I NEVER FELT THE DISTINCT PULSATING IN THE BRAKE PEDAL. THE VEHICLE SEEMED TO ACTUALLY LOOSE ALL BREAKING POWER FOR A INSTANT AND SURGE FORWARD. NO OTHER VEHICLES WERE INVOLVED AND NO ONE WAS INJURED. THE FRONT BUMPER WAS DAMAGED AND THE VEHICLE WAS REPAIRED FOR ABOUT $1,400. AFTER THE VEHICLE WAS REPAIRED, WHILE DRIVING OVER ROUGH SURFACES, AT TIMES, I NOTICED THAT THE BRAKES DID NOT STOP PROPERLY. AT THAT TIME, THERE WAS NO RECALL FOR THE 2010 PRIUS BRAKES. IT FEELS AS IF THE BRAKES STOP WORKING FOR AN INSTANT AND THE VEHICLE SURGES FORWARD. I EVEN REMARKED TO MY WIFE, WHILE DRIVING, THAT THE BRAKED DID NOT FEEL RIGHT WHEN STOPPING SOMETIMES. THERE HAS SINCE BEEN A RECALL FOR THE 2010 PRIUS BRAKES. MY PRIUS IS NOW AT THE TOYOTA DEALERSHIP WHERE THE BRAKE RECALL WILL BE PREFORMED. I HAVE BEEN DRIVING OVER 38 YEARS AND HAVE A VERY GOOD DRIVING RECORD. IT IS MY OPINION, THAT THE ACCIDENT WOULD NOT HAVE OCCURRED HAD THE BRAKES IN MY 2010 PRIUS BEEN WORKING PROPERLY.

2010 TOYOTA PIRIUS ISSUE WITH BRAKES. I RECEIVED A RECALL NOTICE, BROUGHT IT TO DEALER, THEY SUPPOSEDLY FIXED THE PROBLEM. THE RECALL DID NOT CORRECT THE PROBLEM. THERE IS STILL AN ISSUE WITH THE BRAKES. IF YOU HAVE TO BRAKE ON AN UNEVEN SURFACE THE CAR DOES NOT RESPOND IMMEDIATELY. IT SEEMS TO FLOAT OR GLIDE OVER BUMP BEFORE THE BRAKE CATCHES. IT IS A CONSTANT CAUSE OF ANIEXTY WHILE DRIVING. EXTREMELY DANGEROUS BECAUSE YOU CAN CRASH INTO CAR IN FRONT OF YOU ESPECIALLY WHEN CITY DRIVING AS I DO WHEN I COMMUTE TO AND FROM WORK EACH DAY.

ON MY DRIVE HOME FROM THE TOYOTA DEALERSHIP AFTER HAVING THE ABS BRAKE FIX RECALL FIX APPLIED, I APPLIED MY BRAKES TO SLOW DOWN FOR A SPEED BUMP AND WHILE THE CAR ROLLED OVER THE SPEED BUMP THE BRAKES SLIPPED AND THE CAR SEEMED TO SURGE FORWARD. PLEASE NOTE THIS IS IMMEDIATELY AFTER THE CAR RECEIVED THE BRAKE RECALL FIX.

PRIUS 2010 BRAKE DISFUNCTION. FILLED OUT REPORT TO NHSTA APPX 3 MONTHS AGO BUT WAS NOTIFIED CASE WAS CLOSED A FEW DAYS LATER, NO REASON WAS GIVEN FOR CLOSURE. WILL SOMEONE PLEASE FOLLOW UP ON THIS ISSUE.

THE RECALL REPAIR TO THE BRAKE SYSTEM ON MY TOYOTA 2010 PRIUS DID NOT FIX THE INTERMITTANT BRAKE FAILURE THAT IS THE FOCUS OF THE PRIUS RECALL. DEALER INSTALLED "FIX" TWICE BUT THE DELAY IN BRAKING AND FEELING OF ADDITIONAL TORQUE WHEN BRAKING ON ROUGH AND/OR WET PAVEMENT STILL OCCOURS.

2010 PRIUS II - WHEN IN PARK, OR JUST SLIGHTLY ON THE BRAKES AND THE ENGINE SWITCHES FROM ELECTRONIC TO GAS MOTOR, THE CAR ROCKS FORWARD 1-3 INCHES. VERY TERRIFYING, BUT ACCORDING TO KENDALL TOYOTA OF EUGENE, OREGON, THIS IS "NORMAL". I DON' T KNOW OF ANY WORLD IN WHICH A CAR MOVING ON ITS OWN WHILE IN PARK IS NORMAL.

WE OWN A 2010 PRIUS, [XXX] . IT IS ONE OF THE VEHICLES THAT WAS SUBJECT TO THE ABS ACTUATOR ECU UPDATE SAFETY RECALL NOTICE. I TOOK THE CAR IN EARLY THIS MONTH AND HAD THE UPDATE INSTALLED. THE PROBLEM DESCRIBED, REGARDING LIGHT PEDAL PRESSURE AND THE CAR NOT BRAKING CORRECTLY OCCASIONALLY SEEMS TO FIT WELL WITH WHAT I EXPERIENCED. IN THE MIDDLE OF BRAKING, TRYING TO MAKE FULL USE OF THE REGENERATION FEATURE, THE CAR SOMETIMES STOPPED BRAKING MOMENTARILY. I EXPERIENCED THAT THIS WAS MORE LIKELY TO HAPPEN ON A BUMPY ROAD. IN THE 6 MONTHS OR SO I DROVE THE CAR, PRIOR TO THE UPDATE, I EXPERIENCED THIS PROBLEM ROUGHLY 12 TIMES. I AM SAD TO REPORT HOWEVER THAT IN THE TWO WEEKS SINCE THE CAR WAS UPDATED, I HAVE ALREADY EXPERIENCED TWO ADDITIONAL EVENTS AFTER THE UPDATE THAT SEEM EXACTLY LIKE WHAT I EXPERIENCED BEFORE THE UPDATE. I TOOK THE CAR BACK TO MY DEALER (PRESTIGE TOYOTA, IN RAMSEY, NJ) AND SOMEONE THERE TESTED IT AND WAS CONVINCED THAT THE UPDATE WAS INSTALLED. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

2010 TOYOTA PRIUS III ABS RECALL WAS APPLIED BY DEALER TOYOTA CITY OF BROOKLYN PARK, MN ON 3/17/10. PRIOR TO THIS RECALL UPDATE TO MY CAR, I HAD EXPERIENCED THE ISSUE ONCE SINCE PURCHASE OF THE CAR ON 10/23/09. NOW SINCE THE ABS UPDATE HAS BEEN APPLIED, I HAVE EXPERIENCED THE ISSUE 3 TIMES IN 5 DAYS. THE LAST EXPERIENCE WAS TODAY AND THE WORST YET WHERE I FELT I LOST BRAKES COMPLETELY WHILE SLOWING THE CAR AND BRAKING. I ESTIMATE MY SPEED WAS ABOUT 15 MPH GOING OVER A MINOR POT HOLE. *DT

TRUE! GEAR PROBLEM! REMEMBER AIRBUS FLIPPING OUR OF CONTROL WHEN THEY CAME OUT WITH FLY BY WIRE? THE JOY STICK GEAR IS DEFAULT TO SHIFT INTO NEUTRAL WHEN NORMAL PUSH BRING IT IN TO REVERSE. NO WAY TO PUT IT IN NEUTRAL. I THOUGHT THE SAME THING & WAS IN DENIAL UNTIL I REALIZE THAT ITS IMPOSSIBLE TO PUT IT INTO NEUTRAL WHEN THING IS SPEEDING OUT OF CONTROL. DON'T TAKE IT LIGHTLY- I DID BOUGHT A 2010 PRIUS JUST NOW & REALIZE - U CAN'T PUT IT - IN NEUTRAL. I WAS IN DENIAL. ALSO, VENTILATOR FAN SUDDENLY ACCELERATES WHEN U TRY TO SWITCH THE MODES. *DT

I WAS GOING DOWN A HILL (APPROX 20MPH) IN MY SUBDIVISION (NORTH ON HARTER FARMS RD) WHEN I SAW A CAR PULLING OUT ONTO THE ROAD FROM HIS YARD. I APPLIED THE BRAKES HARD FOR ABOUT 100YDS BEFORE ATTEMPTING TO TURN INTO PALIMINO DR TO AVOID A COLLISION. I DID NOT MAKE THE TURN AND HIT A STOP SIGN AND THEN THE GUARD RAIL AT APPROX 5MPH. THERE WAS ABOUT 1-2" OF SNOW ON THE ROAD AND I HAD DRIVEN UP THE SAME HILL FROM A STOP WITHOUT SLIPPING A TIRE JUST 15 MIN PRIOR. I NEVER FELT ANY PULSATION FROM THE ABS DURING THE ATTEMPT TO STOP. AFTERWARDS WHEN I GOT HOME I ATTEMPTED TO STOP HARD (TO TEST THE BRAKES) ON LEVEL GROUND AND AGAIN NEVER FELT THE PULSATION FROM THE ABS SYSTEM. THERE WAS BRAKING BUT I FELT IT WAS GREATLY REDUCED. I HAVE NOT RETURNED THE CAR TO TOYOTA FOR THEIR RECALL YET. IF YOU WISH TO EXAMINE THE CAR YOU MAY. I AM SURE YOU CAN DUPLICATE THE RESULTS. *TR

RE: 2010 TOYOTA PRIUS IV; ON FEBRUARY 27, 2010, I VISITED THE TOYOTA SANTA MONICA SERVICE DEPARTMENT TO HAVE THE ABS SOFTWARE UPDATE INSTALLED. SINCE PURCHASING MY VEHICLE IN SEPTEMBER 2009, UP UNTIL THE DATE OF THE SOFTWARE UPDATE, I EXPERIENCED THE INCONSISTENT FEEL OF THE BRAKES USUALLY ONCE PER WEEK. HOWEVER, SINCE THE SOFTWARE UPDATE, IN THE FIRST WEEK ALONE, THE INCONSISTENT FEEL OCCURRED SEVEN TIMES, WITH THE MOST ALARMING INCIDENT OCCURRING DURING MY MORNING DRIVE TO WORK ON FRIDAY, MARCH 5TH. I WAS DRIVING ON PICO BOULEVARD JUST PAST AVENUE OF THE STARS, GENTLY TAPPING ON MY BRAKES DOWN THE HILL FOR A STOP, WHEN THE CAR BRIEFLY ACCELERATED AND ALMOST REAR-ENDED THE VEHICLE IN FRONT OF ME. ADDITIONALLY, I EXPERIENCED THE BRIEF ACCELERATION TWICE WHILE BRAKING FOR PEDESTRIANS AT CROSSWALKS LAST WEEK. NOW, I AM EXPERIENCING THE SLIPPING SENSATION WITH THE BRAKES ABOUT 2 - 3 TIMES PER WEEK. I HAVE CALLING TOYOTA TOLL-FREE CUSTOMER SERVICE NINETEEN TIMES, BUT EACH TIME RECEIVED AN AUTOMATED MESSAGE STATING THAT THE COMPANY WAS EXPERIENCING HIGH CALL VOLUME AND WOULD BE UNABLE TO ANSWER MY CALL. I SENT TWO FAXES ON MARCH 6TH, ASKING THE COMPANY TO ARRANGE A SECOND SERVICE APPOINTMENT TO REPAIR THE BRAKES. I HAVE YET TO RECEIVE ANY TYPE OF RESPONSE FROM THE COMPANY. TODAY, ON MARCH 20TH, I CALLED TOYOTA SANTA MONICA TO DESCRIBE THE PROBLEM AND REQUEST A SECOND SERVICE APPOINTMENT. WHILE DRIVING DURING MY LUNCH BREAK TODAY, I AGAIN HAD THE BRAKES SLIP ON ME. I SPOKE WITH A SERVICE SUPERVISOR AT TOYOTA SANTA MONICA AT 500 PM TODAY TO ASK FOR A SECOND APPOINTMENT. HE DECIDED TO INSULT MY INTELLIGENCE AND TELL ME THAT WHAT I WAS EXPERIENCING IS A NORMAL FEEL OF THE ABS BRAKES. THIS IS UNACCEPTABLE! I WANT THE CAR REPAIRED. IF TOYOTA CANNOT PREVENT THIS INCONSISTENT FEEL AND SLIPPING SENSATION IN MY BRAKES, THEN I WAS MY PURCHASE CONTRACT TO BE COMPLETELY DISSOLVED. I WILL NOT CONTINUE TO FINANCE A LEMON AND HAVE TOYOTA LIE TO ME ABOUT ITS SAFETY. *TR

I WAS DRIVING DOWN LAUREL CANYON IN LOS ANGELES, I HIT MY BRAKES, THEY ACCELERATED AND I HIT THE CAR IN FRONT OF ME. I DID HAVE THE CODE IN MY 2010 PRIUS FIXED HOWEVER THERE WERE STILL SOME MINOR ACCELERATION PROBLEMS AND I WAS SO ANNOYED THAT I DIDN'T SAY ANYTHING. HOWEVER NOW I HAVE RAN INTO THE CAR IN FRONT OF ME. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE CONTACT WAS DRIVING 5 MPH TRAVELING OVER AN ICY ROAD SURFACE, THE BRAKE PEDAL WAS ENGAGED CAUSING THE VEHICLE TO SLIDE. SUDDENLY, THE VEHICLE CRASHED INTO A SNOW BANK. THE ANTI-LOCK BRAKE SYSTEM WAS INOPERABLE DURING THE FAILURE. THERE WERE NO PRIOR WARNINGS. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALER. THE CURRENT AND FAILURE MILEAGES WERE 400.

2010 PRIUS REPEATEDLY EXHIBITED THE BRAKING DEFECT AT ISSUE IN RECENT RECALL (SUDDEN LURCH FORWARD UPON ENCOUNTERING BUMP WHILE BRAKING TO STOP)--RECALL SERVICE PERFORMED 5 WEEKS AGO. ALTHOUGH THE SUDDEN LURCHING STOPPED (UNTIL TODAY) AFTER THE RECALL SERVICE, THE BRAKING BEHAVIOR THEN HAD A CONSISTENTLY ODD FEELING REQUIRING INCREASED PRESSURE TO FULLY STOP (THOUGH NO MORE SUDDEN LURCHING FORWARD WHEN ENCOUNTERING BUMP). THEN TODAY THE OLD LURCH FORWARD SUDDENLY RECURRED WHEN ENCOUNTERING BUMP WHILE SLOWING TO A STOP. DEALERSHIP CONTACTED AND SAYS THEY HAVE NO FURTHER REMEDY BEYOND RECENT COMPUTER ADJUSTMENT PERFORMED AS PART OF FEBRUARY, 2010 RECALL--BASICALLY TOTALLY DISINTERESTED. *TR

S10 APPROPRIATE HANDLING RE 2010 TOYOTA PRIUS SAFETY COMPLAINTS. *TGW THE CONSUMER STATED THE CRUISE CONTROL DOES NOT IMMEDIATELY CANCEL, CONTROLLING THE THROTTLE UNDER LIGHT BRAKING. THIS ALLOWED THE VEHICLE TO ACCELERATE UP A HILL WHILE THE CONSUMER WAS SIMULTANEOUSLY APPLYING THE BRAKES. THE BRAKE LIGHTS DID NOT COME ON UNDER LIGHT BRAKING AND THE BRAKES DID NOT WORK WHEN BRAKING OVER ROUGH SURFACES SUCH AS RAILROAD TRACKS. *JB

BRAKING ISSUES IN MY 2010 TOYOTA PRIUS- AFTER "RECALL FIX". *TR

I LEASED A 2010 TOYOTA PRIUS IN DECEMBER. IMMEDIATELY UPON LEAVING THE DEALERSHIP I NOTICED THAT THE VEHICLE'S BRAKES DO NOT HOLD WHEN YOU HIT A BUMP/POTHOLE. IN FACT, THE CAR SHOOTS FORWARD AND YOU MUST BE PREPARED. I FILLED OUT THE ON-LINE FORM FOR TOYOTA CUSTOMER SERVICE TO GO ON RECORD WITH THEM I HAD THE RECALL SOFTWARE UPGRADE INSTALLED 3 WEEKS AGO, AND WHILE THE PROBLEM IS MUCH LESS SEVERE, THE UPGRADE FIX DOES NOT FULLY CORRECT THIS ISSUE. THIS MORNING, MY VEHICLE'S BRAKES DID NOT HOLD WHEN I WAS BRAKING TO DRIVE OVER A BUMP IN THE ROAD AT 20MPH. I HAVE HAD A FEW MORE MINOR OCCURRENCES, BUT TODAY WAS NOTICEABLE. *TR

THE PRIUS PURCHASED 1/3/10. ON 3/6/10 THE VEHICLE WOULD NOT STOP AND HIT ANOTHER CAR. THE VEHICLE WAS TOWED TO NORTH HOLLYWOOD TOYOTA. THE BRAKES FAILED TO OPERATE CAUSING THE PRIUS TO HIT ANOTHER CAR. THIS ALL OCCURRED WITHIN THE COUNTY OF LOS ANGELES, CALIFORNIA. THE VEHICLE CAN BE EXAMINED FOR THIS DEFECT. *TR

WHEN STANDING STILL , THE BRAKE PEDAL CAN BE PUSHED TO THE FLOOR, EXTREMELY SPONGY FEEL . TOYOTA SAYS THIS IS NORMAL. WHEN THE BRAKES FAIL DUE TO SOFTWARE ERROR ( RECALL NOTICE WAS RECEIVED TODAY FINALLY ) I CAN ALSO EASILY PUSH THE PEDAL TO THE FLOOR. I DO NOT LIKE THIS FEELING HOPEFULLY THE RECALL WILL TAKE CARE OF THIS . VISIBILITY IS TERRIBLE DUE TO THE ROOF SUPPORTS, ARE PEDESTRIAN ACCIDENTS UP, WE CAN NOT SEE ,TO RETURN TO THE RIGHT LANE AFTER PASSING. *TR

MY 2010 TOYOTA PRIUS HAS HAD A DEFECT THAT I NOTICED AFTER PURCHASE. EVERY TIME I BRAKE, WHEN I HIT A BUMP, MY CAR ACCELERATES. THERE WAS A RECALL IN WHICH WE PARTICIPATED ON MARCH 15, 2010 HOWEVER IT DID NOT CORRECT THE PROBLEM. WE ARE EXTREMELY DISSATISFIED AND FEARFUL OF THE POSSIBLE DANGER IT COULD BRING TO OUR FAMILY AND CHILDREN. *TR

I PREVIOUSLY FILED A COMPLAINT ABOUT MY 2010 PRIUS REGARDING BRAKING FAILURE OVER UNEVEN ROAD SURFACES, CASE #[XXX] . I TOOK MY CAR IN TO OUR LOCAL TOYOTA DEALER YESTERDAY TO HAVE THE ISSUE TAKEN CARE OF (I ALSO RECEIVED A RECALL NOTICE ABOUT THE PROBLEM) I GOT MY CAR BACK AND TODAY I EXPERIENCED THE SAME PROBLEM AGAIN WHILE BRAKING AND GOING OVER A BUMP IN THE ROAD. I WANT YOUR AGENCY TO BE AWARE THAT THE TOYOTA FIX MAY NOT BE WORKING. I WILL BE CONTACTING THE DEALERSHIP AND TOYOTA ABOUT THIS SAFETY ISSUE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT SPEEDS OF APPROXIMATELY 25 MPH ON NORMAL ROAD CONDITIONS, THE ENGINE STALLED WITHOUT WARNING. AFTER SEVERAL ATTEMPTS, THE ENGINE WAS RESTARTED AND THE VEHICLE RESUMED NORMAL OPERATION. THE DEALER WAS CONTACTED IN REGARDS TO THE FAILURE. RECENTLY, THE VEHICLE WAS REPAIRED PER NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE CONTACT WAS CONCERNED THAT THE RECALL REPAIRS WERE INSUFFICIENT AND POTENTIALLY CAUSED THE RECENT FAILURE. THERE WERE NO FURTHER REPAIRS. THE FAILURE MILEAGE WAS 6,905 AND THE CURRENT MILEAGE WAS UNKNOWN.

I HAVE A 2010 TOYOTA PRIUS THAT HAS HAD THE SOFTWARE UPDATE RECALL PERFORMED. SINCE HAVING THE RECALL DONE, THE BRAKES ON THE CAR SEEM TO WORK EVEN WORSE THAN BEFORE. IT STILL OCCASIONALLY FEELS AS THOUGH THE BRAKES ARE SLIPPING WHILE GOING OVER A BUMP, AND THE BRAKES ALSO DO NOT SEEM TO WORK AS WELL UNDER NORMAL OPERATION. *TR

I HAD MY 2010 TOYOTA PRIUS SERVICED IN ORDER TO ADDRESS A LOSS OF BRAKE POWER WHEN BRAKING WHILE GOING OVER A BUMP. AFTER THE SERVICING THE PROBLEM HAS CONTINUED. IT IS A BRIEF EVENT BUT CONCERNS ME AS WHEN IT HAPPENS IT FEELS MOMENTARILY AS THOUGH THE CAR IS SPEEDING UP. *TR

I BOUGHT A 2010 PRIUS IN JUNE 2009. SHORTLY AFTER GETTING THE CAR I NOTICED THAT IT SEEMED TO "SLIP" WHEN I WAS DRIVING SLOWLY OVER UNEVEN SURFACES (RAILROAD TRACKS, UNEVEN ROAD SURFACES, UTILITY COVERS). WHEN THE RECALL WAS ANNOUNCED I REALIZED THE "SLIP" I WAS FEELING WAS THE BRAKES NOT WORKING MOMENTARILY. I WENT TO A DEALER AND THE CAR WAS SERVICED. HOWEVER, I HAVE CONTINUED TO EXPERIENCE THIS ISSUE EVEN AFTER THE SUPPOSED FIX. *TR

TL*-THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 45 MPH. WHEN BRAKING THERE WAS A DELAY RESPONSE. THE FAILURE OCCURRED THREE DAYS AFTER THE RECALL REMEDY REPAIR WAS PERFORMED ON THE VEHICLE. THE RECALL WAS UNDER NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE MANUFACTURER WAS NOTIFIED OF THE MALFUNCTION AND THERE WAS NO RESOLUTION. THE FAILURE MILEAGE WAS 11,000.

I HAVE A 2010 TOYOTA PRIUS - IT HAS 6,000 MILES ON IT. TWO TIMES THE BRAKES HAVE FAILED TO ENGAGE WHEN I HAVE STEPPED ON THE BRAKE PEDAL. IT TAKES APPX. 2 TO 3 SECONDS BEFORE THE BRAKES ENGAGE. *TR

I BROUGHT MY 2010 PRIUS TO SERVICE THE RECALLED BRAKE SOFTWARE ISSUE. PREVIOUS TO THIS, I NOTICED BRAKING PROBLEMS WHEN ON SLIPPERY AND/OR BUMPY ROADS WHERE THE BRAKES WOULD 'STOP BRAKING' FOR 1-2 SECONDS, AND GIVE A FEELING THAT THE CAR WAS LUNGING FORWARD WHEN ATTEMPTING TO DECELERATE. I BROUGHT THE CAR IN TO HAVE THE BRAKE SOFTWARE UPGRADED. ON MARCH 12TH I WAS DRIVING ON WET ROADS, WITH SOME POTHOLES, IT WAS FAIRLY BUMPY. I SLOWED THE CAR AS USUAL AND NEAR THE STOPLIGHT THE CAR FAILED TO DECELERATE FOR 1-2 SECONDS, AND I THOUGHT I WAS GOING TO CRASH INTO THE CAR IN FRONT OF ME. AFTER 1-2 SECONDS THE BRAKES CAUGHT AGAIN AND I HAD TO SLOW DOWN MUCH MUCH FASTER TO AVOID HITTING THE VEHICLE IN FRONT. MY CONCERN IS THAT THE BRAKE SOFTWARE UPGRADE DID NOT FIX THE PROBLEM, AND I CONTINUE TO BE AT RISK. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING AT 20 MPH TRAVELING OVER A POT HOLE THE CONTACT NOTICED THAT THE VEHICLE HAD SUDDENLY ACCELERATED WITHOUT WARNING. IN ORDER TO STOP THE VEHICLE THE BRAKES WERE APPLIED. THE FAILURE MILEAGE WAS 3,500 AND THE CURRENT MILEAGE WAS 3,700.

I RECENTLY GOT A RECALL ON MY 2010 PRIUS BUT STILL HAVING A PROBLEM WITH BRAKES. I WENT TO CHECK ON THE PROBLEMS TODAY (SATURDAY, MARCH 13, 2010), HOWEVER, THEY SAID THE LEAD MECHANIC WAS NOT THERE AND COULD NOT HELP ME WITH DISCUSSING PROBLEMS. THEY WANTED ME TO SET UP AN APPOINTMENT AGAIN DURING THE WEEKDAYS (WHICH WILL BE A MORE PROBLEMATIC FOR ME SINCE I WORK FULL TIME AND THEY DON'T OFFER "RENTAL" SERVICE EITHER). I HAVE A GREAT FEAR OF DRIVING THIS CAR AGAIN ON THE ROAD WHERE THERE COULD BE LOTS OF UNEXPECTED ACCIDENTS. I GENERALLY DON'T UNDERSTAND THAT THERE WAS NOBODY WHO COULD TAKE A LOOK AT MY VEHICLE AND GIVE ME SOME ADVICE WHEN THERE ARE LOTS OF CUSTOMERS WHO ARE LOOKING TO GET SOME HELP DURING THE WEEKEND. MY BRAKE STILL SLIPS AND I LOOSE MY CONTROL OVER MY BRAKES WHEN I GO OVER POT HOLES OR SLOWING DOWN AND MAKING TURNS. AGAIN, THE "RECALL" SERVICE DID NOT GIVE ME ANY SOLUTIONS. I DISCUSSED ABOUT THIS PROBLEM AGAIN WITH SALES REPRESENTATIVE AT TOYOTA DEALERSHIP AND ASKED THEM POSSIBLE OPTIONS TO RETURN MY CAR OR GETTING A NEW ONE SINCE IT'S BEEN QUITE LONG DAYS EVER SINCE I STARTED COMPLAINING ABOUT THE SAME PROBLEMS, AND THEY SAID NO TO EVERYTHING. I AM NOT SURE HOW I CAN DRIVE THIS "UNSECURED" CAR ANYMORE. *TR

WHILE DRIVING ON A RESIDENTIAL STREET AT APPROXIMATELY 25 TO 30MPH, I PUT ON BRAKES FOR A SPEED BUMP AND MY 2010 PRIUS LOST BRAKE POWER FOR A (VERY SHORT) PERIOD OF TIME. THIS SAME EVENT HAPPENED ON 3 SEPARATE OCCASIONS FROM NOVEMBER OF 2009 TO THE PAST WEEK. IN ALL CASES THE STREET WAS DRY AND THE CAR WAS TRAVELING AT OR BELOW THE SPEED LIMIT. ONE OCCURRENCE WAS AS DESCRIBED ABOVE AND THE OTHER TWO WE ON SOMEWHAT OF A ROUGH SPOT IN THE ROAD. *TR

ON FEB 1, 2010, I WAS APPROACHING A STOP LIGHT INTERSECTION AT ABOUT 7 MPH. WHEN APPLYING THE BRAKES IT WAS LIKE STEPPING ON A SOLID STEEL POLE OR ICE SKATES. THE PEDAL WOULD NOT DEPRESS AND THE BRAKES WOULD NOT ENGAGE. I RELEASED BRAKE PRESSURE AND AGAIN PRESSED THE PEDAL AND THEN THE BRAKES OPERATED SATISFACTORILY. THE STREET WAS SMOOTH ASPHALT, DRY AND IN GOOD CONDITION WITHOUT BUMPS. ON FEB 28, 2010 THE DEALER (LAKE CITY TOYOTA) ACCEPTED THE VEHICLE AND PERFORMED THE "SERVICE CAMPAIGN AOB ABS ACTUATOR ECU UPDATE". *TR

WE HAVE A 2006 TOYOTA PRIUS. EVER SINCE WE BOUGHT IT, WE'VE BEEN EXPERIENCING A PROBLEM WHICH WAS POOH-POOHED BY THE DEALER, BUT NOW WE THOUGHT IT BEST TO REPORT IT. THIS PROBLEM MANIFESTS ITSELF WHEN THE BRAKE IS APPLIED AND WE DRIVE OVER AN UNEVEN SURFACE OR A VERY COMMON IRREGULARITY IN THE PAVEMENT....LIKE WHEN DRIVING OUT OF OUR DRIVEWAY, WHICH INVOLVES A SMALL ELEVATION GRADE CHANGE BETWEEN THE DRIVEWAY AND THE STREET. THE BRAKING ACTION CHANGES SUDDENLY, AND THE CAR SEEMS TO LOOSE BRAKING MOMENTARILY. WE EXPERIENCE THIS AS A LURCH. THIS IS UNEXPECTED, AND WE'VE NEVER HAD A CAR WHICH DID THIS IN OUR 40 YEARS OF DRIVING EXPERIENCE. *TR

2010 PRIUS BRAKE ECU UPDATE DID NOT SOLVE PROBLEM. THIS IS AN UPDATE TO A PRIOR COMPLAINT, REFERENCE # 10300235. THE BRAKES FAILED UNDER THE SAME CIRCUMSTANCES AND EXHIBITED THE SAME BEHAVIOR AS IN THE PREVIOUS COMPLAINT. THE DEALER, HUNTINGTON TOYOTA, ALLEGEDLY UPDATED THE ECU ON 2/24/2010. THE CAR LOSES BRAKING ABILITY BRIEFLY WHILE SLOWING DOWN (BELOW 10 MPH) AND PASSING OVER A ROUGH ROAD SURFACE OR POTHOLE. THE SENSATION IS ONE OF THE CAR SURGING FORWARD. THIS HAS HAPPENED SEVERAL TIME SINCE THE UPGRADE, THE LATEST OCCURRENCE BEING 3/11/2010. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. HE STATED WHEN DRIVING OVER UNEVEN ROAD SURFACES OR SPEED BUMPS IN THE ROAD THE VEHICLE WOULD MOMENTARILY LOSE BRAKING POWER. ALSO, WHEN DEPRESSING THE BRAKE PEDAL OVER ANY TYPE OF UNEVEN ROAD SURFACE THE VEHICLE WOULD SURGE MOMENTARILY. THE DEALER WAS CONTACTED AND INFORMED THE CONTACT THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. THE FAILURE PERSISTED AND THE DEALER WAS CONTACTED A SECOND TIME WHERE THE CONTACT WAS INFORMED THAT THEY WERE AWARE OF THE ISSUE, HOWEVER DID NOT HAVE AN EXPLANATION OR A REMEDY FOR THE FAILURE. THE FAILURE PERSISTED AND THE DEALERSHIP WAS CONTACTED A THIRD TIME WHERE THE CONTACT WAS ADVISED THERE WAS AN OPEN RECALL ON THE VEHICLE NHTSA RECALL NUMBER: 10V039000:SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE) AND TO BRING THE VEHICLE IN TO PERFORM THE RECALL SERVICE. AFTER RECALL REPAIRS WERE PERFORMED ON THE VEHICLE, THE CONTACT EXPERIENCED THE EXACT SAME FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 1,000 AND THE CURRENT IS 7600.

2010 TOYOTA PRIUS GAVE ME IN TWO DIFFERENT OCCASIONS THE FEELING THAT THE BRAKE WAS NOT WORKING. IN BOTH CASES I WAS DRIVING SLOW AND TRACTION CONTROL LIGHT CAME ON. IN ONE CASE I WAS BACKING UP FROM MY GARAGE; IN THE OTHER CASE I WAS TRANSITIONING FROM A SMALL DOWNHILL EXIT TO A FLAT STREET. *TR

TODAY I DROVE THE CAR TO SEE WHAT WOULD HAPPEN IF THE CAR WAS ACCELERATING AND I WANTED TO STOP IT OTHER THAN PUTTING ON THE BRAKES AND HITTING THE PARK BUTTON. I WAS TRYING TO REPRODUCE THE CONDITIONS WHICH HAVE RESULTED IN NUMEROUS ACCIDENTS AND MORE THAN ONE LIFE. WHILE SLIGHTLY ACCELERATING I FIRST TRIED TO STOP THE CAR BY PRESSING THE POWER BUTTON. THIS DID NOTHING. I THEN PRESSED THE BRAKE PEDAL ON THE LEFT SIDE WHICH IS YOUR HAND BRAKE, HARD UNTIL THE BRAKE LIGHT CAME ON AND THE ALARM SOUNDED. IN SPITE OF THIS THE CAR KEPT GOING! THE ONLY WAY I COULD STOP THE CAR WAS BY STOPPING THE CAR WITH THE FOOT BRAKE AND THEN PRESSING THE PARK BUTTON. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 30 MPH THE BRAKES WERE ENGAGED WITH A SLOW POWER RESPONSE. THE VEHICLE HAD A PRIOR RECALL REPAIR UNDER NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE FAILURE OCCURRED INTERMITTENTLY. THE FAILURE MILEAGE WAS 10,000. THE CURRENT MILEAGE WAS 10,600.

I HAVE A 2010 PRIUS. MY CAR WAS SURGING BEFORE BRAKING ON BUMPY TERRAIN. I BROUGHT THE CAR IN FOR REPAIR TO THE DEALER, AS PER THE RECALL. THE PROBLEM IS STILL PRESENT. I STILL FEEL A SURGE WHILE BRAKING OVER BUMPS. I CONTACTED THE SERVICE DEPARTMENT OF TOYOTA AND WAS TOLD THERE WAS NOTHING THEY COULD DO TO FIX THE PROBLEM AND SUGGESTED I CALL TOYOTA HEADQUARTERS IN CALIFORNIA. I HAVE ATTEMPTED THREE TIMES TO REPORT MY COMPLAINT AND ON EACH OCCASION WAITED ON THE PHONE OVER A HALF HOUR WITH NO ANSWER. *TR

I HAVE FILED A COMPLAINT HERE BEFORE ABOUT MY 2010 TOYOTA PRIUS, WHERE THE BRAKES WERE SUPPOSEDLY FIXED LAST WEEK BY TOYOTA FOLLOWING THE RECALL. HOWEVER, JUST TODAY THE BRAKING PROBLEM, WHEN HITTING BUMPS IN THE ROAD, SEEMS TO NOT HAVE BEEN FIXED AT ALL. DRIVING IN THE DC AREA, WHERE THERE ARE A LOT OF POTHOLES AROUND, IT IS EASY TO TEST WHETHER THE BRAKES ARE FIXED OR NOT. WHILE DRIVING ALONG THE ROAD TODAY, NEARING MY HOUSE, I HIT A POTHOLE, AND JUST AS IT HAD BEEN HAPPENING BEFORE, THE BRAKES SEEMED TO COMPLETELY LET GO AND THE CAR LURCHED FORWARD FOR A SPLIT SECOND UNTIL THE BRAKES SEEMED TO REGAIN POWER AND I WAS ABLE TO PRESS DOWN ON THEM AGAIN. PRIOR TO THAT INCIDENT, AND NOT 10 MINUTES EARLIER, I HIT A SMALL POTHOLE WHILE BRAKING LIGHTLY AND THE BRAKES GAVE OUT JUST SLIGHTLY. IT'S AN UNMISTAKABLE FEELING, HAVING EXPERIENCED IT NUMEROUS TIMES BEFORE TOYOTA FINALLY DECIDED TO RECALL THE 2010 PRIUS. *TR UPDATED IVOQ 07/08/10.*JB

MY 2010 PRIUS BRAKES FAILED MOMENTARILY TWICE WHILE GOING OVER RUTS IN THE ROAD; I WAS ABLE TO KEEP CONTROL OF THE CAR AND THE BRAKES RESUMED WORKING RIGHT AFTERWARDS. *TR

I HAD A BRAKING ISSUE, THE CAR WOULD NOT BRAKE AFTER HITTING SEVERAL POTHOLES AND GOING INTO AN INTERSECTION. THIS IS POST RECALL. THE RECALL WAS PERFORMED BY TOYOTA THREE WEEKS AGO. THIS IS THE THIRD INCIDENT FOR THIS VEHICLE WITH IDENTICAL SYMPTOMS. AFTER COASTING FOR 10 FEET OR SO, THE VEHICLE DID APPLY THE BRAKES. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHENEVER THE CONTACT ATTEMPTS TO BRAKE WHILE TRAVELING OVER A ROUGH SURFACE THE BRAKES WILL HESITATE TO ENGAGE INCREASING THE STOPPING DISTANCE. PRIOR TO THE RECENT FAILURE THE CONTACT HAD TAKEN HER VEHICLE TO THE DEALERSHIP WHERE NHTSA RECALL # 10V039000 WAS PERFORMED ON HER VEHICLE. THE CURRENT AND FAILURE MILEAGES WERE 1300. UPDATED 05/10/10 *BF UPDATED 05/10/10*JB

2010 PRIUS -ALREADY HAD THE BRAKE SOFTWARE FIX -CONTINUES TO ACCELERATE SLIGHTLY WHEN IT GOES OVER POTHOLES WITH THE BRAKE PEDAL DEPRESSED - USUALLY LOW SPEED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. SHE CONFIRMED SHE HAS EXPERIENCED BRAKE FAILURE SEVERAL TIMES IN THE VEHICLE. WHILE ATTEMPTING A RIGHT TURN OVER RAILROAD TRACKS WITH HER FOOT ON THE BRAKE PEDAL, THE VEHICLE ABNORMALLY LUNGED FORWARD AND BEGAN TO ACCELERATE. SHE CONTINUED TO DEPRESS THE BRAKE PEDAL UNTIL THE VEHICLE CAME TO A STOP. SHE ALSO NOTICED THAT WHEN DRIVING UPHILL, THE VEHICLE WAS HESITANT TO ACCELERATE. THE VEHICLE HAD NOT YET BEEN TAKEN TO THE DEALER FOR INSPECTION. THE FAILURE MILEAGE WAS 65,000 AND THE CURRENT WAS 96,077.

A SAFETY RECALL PROCEDURE PERFORMED RECENTLY ON THE 2010 PRIUS TO FIX THE LURCHING BRAKES HAS NOT BEEN WORKING OUT. I HAD IT DONE RECENTLY, AND THIS IS PAST THE RECALL. IN MORE THAN 3 OCCASIONS RECENTLY I ALMOST HIT THE CAR IN FRONT OF ME WHILE GOING OVER A MANHOLE STOPPING OVER FOR A SIGNAL GOING AS LOW AS 25MPH. THE CAR JUMPED FORWARD DESPITE MY NORMAL BRAKING TO GET IT TO STOP, FORCING ME TO BRAKE HARD COMING TO A FORCED STOP. I AM AFRAID SOMEDAY I MAY NOT BE SO LUCKY !! WISH, TOYOTA PUT MORE THOUGHT INTO THEIR SOLUTIONS THAN RUSHING INTO THE MARKET WITH SUB STD. PROCEDURES & CARS !! *TR

2010 PRIUS 3 TIMES I HAVE THE BRAKES GRAB AND LOCKED SEVERAL TIMES IN A ROW WHEN I HAVE BEEN APPLYING VERY SLOW PRESSURE. TWICE WHILE BACKING OUT FROM PARKING SPACE AND ONCE WHILE GOING FORWARD SLOWLY IN MY DRIVEWAY. THEY THEN BEGAN ACTING NORMALLY. I AM CONCERNED THAT THIS COULD HAPPEN IN TRAFFIC CAUSING AN ACCIDENT. I CAN'T FIND A PLACE AT TOYOTA TO REPORT. I WAS IN AN ACCIDENT WITH 2002 TOYOTA PRIUS WITH UNEXPLAINED ACCELERATION IN OCTOBER 2009-ALREADY REPORTED. *TR

BRAKE PROBLEM WITH 2010 PRIUS. I WAS CROSSING A POTHOLE ON STREET AND PUT THE BRAKE ON BEFORE THE FRONT WHEELS GET INTO THERE. WHILE THE FRONT WHEELS ENTER THE HOLE, I FELT MY CAR SUDDENLY LOST BRAKING AND SPEED UP. IT LASTED FOR LESS THAN 1 SEC. I GUESS. THEN, EVERYTHING WAS NORMAL. *TR

MY 2010 PRIUS HAD THE BRAKE SOFTWARE UPDATED BEFORE I PURCHASED IT. I HAVE OWNED THE CAR FOR 12 DAYS. DURING THAT TIME I HAVE EXPERIENCED A BRAKING PROBLEM ON 3 INSTANCES. IN EACH CASE I WAS SLOWING DOWN AT A CONSTANT RATE OF DECELERATION WHEN I HIT A POTHOLE OR OTHER ROUGH SURFACE. FOR A SPLIT SECOND THE RATE OF DECELERATION WAS INTERRUPTED. IN OTHER WORDS IT FELT LIKE I HAD LET UP ON THE BRAKE WHICH I DID NOT DO. ON THE THIRD INCIDENT MY WIFE WAS A PASSENGER IN THE CAR AND ALSO NOTICED THAT FOR A SPLIT SECOND IT FELT LIKE I EASED OFF THE BRAKE. I TOOK MY CAR TO THE TOYOTA DEALER TO MAKE SURE THE SOFTWARE HAD BEEN UPDATED. THEY CONFIRMED THAT IT HAD AND MAKE A NOTE OF MY EXPERIENCE. I HAVE READ ABOUT THE PROBLEM WITH THE BRAKES ON THE HYBRID FORD FUSION AND THE PROBLEM WITH MY CAR MAY BE THE SAME. THAT IS THAT THE ROAD BUMP PROMPTS THE COMPUTER TO MOMENTARILY INTERRUPT THE REGENERATIVE BRAKING AND THUS MAKE IT FEEL LIKE THE BRAKES FAILED. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE DRIVER STATED THE HER VEHICLE WAS RECENTLY REPAIRED PER THE VEHICLE SPEED CONTROL RECALL. THE FAILURE CONTINUED TO OCCUR. IMMEDIATELY AFTER THE REPAIR WAS MADE, SHE WAS DRIVING 30 MPH OVER A POTHOLE; HOWEVER, WHEN SHE ENGAGED THE BRAKE PEDAL, THE VEHICLE ACCELERATED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 10,500 AND THE CURRENT MILEAGE WAS 11,000.

I JUST PICKED UP MY 2010 TOYOTA PRIUS FROM THE DEALERSHIP FOR THE SECOND TIME SINCE THE BRAKE RECALL. THIS IS THE THIRD TIME MY PRIUS HAS BEEN IN FOR SERVICE ON MY BRAKES. THEY PERFORMED THE RECALL AND KEEP TELLING ME THAT MY CAR IS FUNCTIONING PROPERLY AND THAT ALL HYBRIDS BRAKE THIS WAY. I WILL ADMIT MY PRIUS STOPS QUICKER THAN BEFORE THAN THE RECALL HOWEVER I STILL NOTICE THAT IT SURGES FORWARD BEFORE THE CARE STOPS AT TIMES. IN THE 2 WEEKS I HAD THE CAR BACK AFTER THEY PERFORMED THE RECALL I AND MY HUSBAND NOTICED THAT THE BRAKES STILL SURGED FORWARD BEFORE STOPPING. I PICKED UP MY CAR TODAY AND I NOTICED IT AGAIN ON MY WAY HOME. WHAT IS IT GOING TO TAKE TO GET THIS CAR FIXED PROPERLY? I DO NOT FEEL SAFE DRIVING IT AROUND, AND I HAVE YOUNG CHILDREN. I WANT SOMEONE TO LOOK INTO WHY THESE RECALLS ARE MAKING THE PROBLEM ALITTLE BETTER BUT NOT FIXING THE PROBLEM. IF TOYOTA DOES NOT KNOW HOW TO FIX IT THEN MAYBE THEY NEED TO BUY THESE UNRELIABLE DEATH TRAPS BACK FROM THEIR CONSUMERS AND STOP FEEDING US A LINE ABOUT HOW THIS IS NORMAL AND ALL HYBRIDS DO THIS. *TR

I VISITED MY LOCAL DEALERSHIP FOR REPAIR OF THE BRAKE RECALL OF THE 2010 PRIUS IN EARLY FEBRUARY. I DO NOT BELIEVE THAT THIS REPAIR HAS FIXED THE PROBLEM. A FEW DAYS AFTER THE FIX, MY CAR SEEMED TO ACCELERATE AS I WAS BRAKING AND HAPPENED TO BE GOING OVER A POT HOLE. THEN AGAIN JUST A FEW DAYS AGO, I WAS BRAKING TO MAKE A TURN AND HIT A VERY ROUGH PATCH OF ROAD. MY CAR AGAIN NOTICEABLY SEEMED TO ACCELERATE EVEN THOUGH I WAS BRAKING. *TR

COMPLAINT REGARDING: 2010 TOYOTA PRIUS. SINCE I PURCHASED THE CAR IN SEPTEMBER OF 2009, THE BRAKES FAIL WHEN I AM BRAKING AND HIT A BUMP, POTHOLE, OR UNEVEN ROAD SURFACE. THE BRAKES FAIL FOR A SECOND OR TWO, AND SOMETIMES THE CAR LURCHES FORWARD. THE ISSUE OCCURS APPROXIMATELY ONCE A DAY, EVERY DAY. ON MARCH 6, 2010, I HAD THE RECALL SOFTWARE FOR THE 2010 PRIUS DONE IN THE SERVICE DEPARTMENT AT THE MIKE CALVERT TOYOTA DEALERSHIP IN HOUSTON, TEXAS. ON THE WAY HOME, I EXPERIENCED THE BRAKE FAILURE AGAIN WHEN I WAS BRAKING AND DROVE OVER A SMALL POTHOLE. I EXPERIENCED THE PROBLEM LATER THAT DAY WHEN BRAKING TO STOP AT A RED LIGHT, THE PAVEMENT SURFACE DESCENDED SLIGHTLY BENEATH THE CAR, THE BRAKES LAPSED, AND THE CAR LURCHED FORWARD. I CALLED THE DEALERSHIP. THEY REFERRED TO THE MATERIALS SUPPLIED BY TOYOTA AND TOLD ME TO CALL TOYOTA AT 1-800-331-4331 TO NOTIFY TOYOTA THAT THE RECALL FIX DID NOT WORK. UPON CALLING THIS NUMBER AND NAVIGATING THE OPTIONS ON THE AUTOMATED SYSTEM, I SAT THROUGH A LONG RECORDING STATING THAT THERE WAS A RECALL OF THE 2010 PRIUS. THE OPTION AVAILABLE TO SPEAK WITH AN AGENT DID NOT ALLOW ME TO DO SO. *TR

BRAKES TEMPORARILY DISENGAGE WHEN BRAKING. THIS HAPPENS SEVERAL TIMES A WEEK. TOYOTA SAYS THEY INSTALLED THE PROGRAMMING FIX A FEW WEEKS AGO BUT THE PROBLEM CONTINUES TO HAPPEN. I CONTACTED THE DEALERSHIP AND THEY TOLD ME THERE WAS NOTHING THEY COULD DO ABOUT IT, THAT I SHOULD CONTACT TOYOTA CUSTOMER SERVICE. THE FAILURE OCCURS WHEN I'M BRAKING AND HIT A BUMP OR UNEVEN PAVEMENT. THE BRAKES STOP BRAKING FOR JUST A MOMENT. DEPENDING ON MY SPEED AT THE TIME, IT CAN FEEL LIKE A MOMENTARY PAUSE OR A SUDDEN, HEAVY PUSH FROM BEHIND. IT ALWAYS FEELS LIKE I"M SLIDING OVER THE BUMP. *TR

I WAS DRIVING MY BRAND NEW, 3 WEEKS OLD, 2010 TOYOTA PRIUS ON A RURAL ROAD IN CLARK COUNTY WASHINGTON ON THURSDAY, MARCH 4, 2010, WHEN I ATTEMPTED TO SLOW DOWN TO MAKE A VERY SHARP LEFT TURN. I WAS APPLYING MY BRAKES WHEN ALL OF THE SUDDEN I REALIZED I WAS NOT SLOWING DOWN MUCH AND WAS NOT GOING TO MAKE THE TURN. I HAVE MANEUVERED THIS TURN HUNDREDS OF TIMES AND KNOW THAT ONE MUST SLOW TO ALMOST A CRAWL TO MAKE THE TURN. I TRAVEL THIS AREA AT LEAST 1-2 TIMES PER WEEK, SO I WAS NOT UNFAMILIAR WITH THE TURN. IT FELT LIKE MY CAR INITIALLY SLOWED SOME, BUT THEN SLOWING CEASED AND I ENDED UP ON EMBANKMENT. THE FRONT OF MY CAR WAS DAMAGED SEVERELY. I WAS NOT HURT BUT LEFT WITH A VERY FRIGHTENING EXPERIENCE TO DEAL WITH. I AM A EXCELLENT DRIVER AND HAVE NEVER HAD A WRECK IN THE 31 YEARS I HAVE BEEN DRIVING. I BELIEVE MY BRAKES INITIALLY ENGAGED, BUT THEN DUE TO THE RURAL ROAD SURFACE, AND PEBBLES LEFT ON THE ROAD FROM PREVIOUS ICE AND SNOW, MAY HAVE CAUSED MY BRAKES TO NOT WORK AS THEY SHOULD HAVE. I ATTEMPTED TO CONTACT TOYOTA BUT THEY ARE CLOSED DUE TO IT BEING THE WEEKEND. MY CAR IS AT THE AUTO BODY SHOP AS I WRITE THIS LETTER. MY CONCERN IS THAT I WAS ALLOWED TO PURCHASE A VEHICLE, THAT IS ON THE RECALL LIST WITH SUCH A DANGEROUS DEFECT SUCH AS "THE BRAKES NOT WORKING PROPERLY." I HAVE A TEENAGE SON WHO IS JUST LEARNING TO DRIVE AND WOULD IT HAVE BEEN HIM, THE ACCIDENT MAY HAVE BEEN WORSE. PLEASE ADVISE HOW YOU BELIEVE I SHOULD PROCEED. I AM VERY CONCERNED, UPSET, AND DO NOT FEEL SAFE IN THIS CAR! AND I CERTAINLY DO NOT WANT TO TRANSPORT MY CHILDREN, OTHER FAMILY MEMBERS AND FRIENDS IN AN UNSAFE VEHICLE THAT I JUST SPENT $33,000.00 ON. I WAS TOLD WHEN I PURCHASED THE CAR THAT IT WOULD BE SAFE, FINE TO DRIVE, AND MAY NOT EVEN BE ON THE RECALL LIST. IT IS ON THE LIST AND IT IS NOT A SAFE VEHICLE AS FAR AS I AM CONCERNED. *TR

MY 2010 TOYOTA PRIUS WILL SOMETIMES BRAKES VERY HARD UNDER LIGHT BRAKE PEDAL PRESSURE WHEN BACKING UP. IT HAPPENS EVERY 2 TO 3 DAYS AND CAN BE WHEN THE CAR IS HOT AND JUST DRIVEN, OR COLD AND BEEN PARKED FOR HOURS. WHEN THIS OCCURS,IT WILL CONTINUE TO HAPPEN NO MATTER HOW MANY TIMES THE BRAKES ARE APPLIED IN REVERSE, WITH THE LIGHTEST OF BRAKE PRESSURE, THE BRAKE APPLY VERY HARD. THEN AFTER THE EVENT, SAY A MILE OR TWO LATER, WHEN BACKING UP, THE BRAKE WILL ACT NORMALLY TO THE BRAKE PEDAL PRESSURE EXERTED. *TR

I HAVE A 2010 PRIUS WHICH I TOOK TO CHAMPION TOYOTA IN HOUSTON FOR THE RECALL REPAIR ON FEBRUARY 12. ACCORDING TO THEM THEY PERFORMED THE BRAKE RECALL SOFTWARE REPAIR. HOWEVER, ON 3/3 WHEN I WAS DRIVING HOME FROM WORK I EXPERIENCED THE BRAKE FAILURE PROBLEM AGAIN. *TR

AFTER THE RECALL SERVICE ON MY 2010 TOYOTA PRIUS, THE BRAKING SYMPTOM STILL OCCURRED ON TWO OCCASIONS ON MARCH 2, 2010 AND ON MARCH 4, 2010. IN BOTH CASES THERE WAS A DELAY IN BRAKING WHEN THE BRAKE WAS APPLIED WHILE ON A MODERATELY BUMPY ROAD SURFACE. ALTHOUGH DIFFICULT TO MEASURE THE DELAY MAY HAVE BEEN BRIEFER THAN PREVIOUSLY, BUT IT WAS STILL SUFFICIENT THAT IT WOULD HAVE BEEN A SAFETY HAZARD IF THERE WAS A VEHICLE OR OBSTRUCTION IN FRONT OF ME. *TR

MY DAUGHTER WAS DRIVING THE 2010 TOYOTA PRIUS INTO A SHOPPING CENTER'S PARKING LOT. SHE NOTICED SOME BLACK ICE ON THE GROUND AND STEP ON THE BRAKE. THE CAR DIDN'T STOP AND SLIP ON THE ICE AND THEN HIT THE CURB. THE REPAIR COSTS OVER $7300, AND IT'S THE TOYOTA DEALER DID THE REPAIR WORK. BACK IN LATE OCTOBER AND EARLY NOVEMBER TIME FRAME, WHEN I WAS DRIVING THE CAR OVER A SPEED BUMP WITH SPEED AROUND 15M/H, THE BRAKE DIDN'T WORK, THE CAR JUST SURGE FORWARD, EVENTUALLY SLOW DOWN AFTER 1 SECOND OR SO. *TR

I TOOK MY 2010 TOYOTA PRIUS IN FOR THE RECALLS AND IT STILL HAS THE SAME ACCELERATION PROBLEM. *TR

DRIVING 2010 TOYOTA PRIUS. SEEMED TO HAVE 'SKIPPED' FORWARD WHILE GENTLE BRAKING OVER BUMPY ROAD (SMALL BUMPS). CAR HAD ALLEGEDLY HAD ELECTRIC REPAIR TO ABS FOR THE PRIUS, HOWEVER; WILL TAKE TO ANOTHER DEALER TO CONFIRM. I REALIZE THERE ARE PRIVACY CONCERNS AS AN OWNER, AND I'M NOT LOOKING TO PUT EMPHASIS ON MYSELF, HOWEVER; AFTER SUPPOSED REPAIRS TO THE BRAKE SYSTEM I AM WORRIED THAT THE ELECTRONIC UPDATE TO THE PRIUS 2010 WAS NOT SUFFICIENT. THE SLIGHT 'JOLT' THAT I FELT MADE ME THINK INITIALLY I WAS BUMPED IN THE BACK OF MY CAR. THANKS AGAIN FOR INVESTIGATING THIS. *TR

TOYOTA PRIUS 2010 ABS SOFTWARE UPDATE DOES NOT FIX THE ISSUE - ABS TURNS OFF AND VEHICLE ACCELERATES WHEN BRAKING AND I HIT A BUMP - SOFTWARE UPDATE WAS PERFORMED ON 2/12/2010. *TR

MY VEHICLE SURGED FORWARD WHILE I APPLIED THE BRAKE AND WAS TRAVELING OVER A SMALL PATCH OF ROUGH SURFACE. IT FELT LIKE THE GAS PEDAL HAD BEEN STOMPED, BUT I WAS ONLY USING THE BRAKES. *TR

HAD THE RECALL WORK DONE ON MY 2010 PRIUS LAST WEEK, AND THE PROBLEM (SURGE WHEN BRAKING OVER POTHOLE, RR TRACKS, ETC) HAS NOW HAPPENED TWICE SINCE THEN. I JUST SPOKE TO THE SERVICE DEPARTMENT AT PARKWAY TOYOTA IN ENGLEWOOD CLIFFS, WHO TOLD ME THAT, WHILE THE RECALL FIX WOULD LESSEN THE "SURGE" PROBLEM, IT WOULD NEVER TOTALLY GO AWAY BECAUSE OF THE BRAKING SYSTEM ITSELF. SHOULDN'T THIS HAVE BEEN EXPLAINED TO ME, BY TOYOTA INC, OR PARKWAY? THIS IS STILL A VERY DISCONCERTING FEELING. THOUGHT THE RECALL WAS A TOTAL FIX, NOT A PARTIAL ONE. *TR

I EXPERIENCE THE BRAKE FAILURE ON PRIUS 2010, I TOOK THE CAR IN THE DEALER TO FIX IT BUT DEALER TOLD ME THAT THE FIRMWARE ALREADY UP TO DATE ON MY CAR. *TR

I TOOK MY 2010 TOYOTA PRIUS INTO THE DEALER TO FIX THE BRAKING PROBLEM; HOWEVER, I AM STILL EXPERIENCING THE PROBLEM ON A DAILY BASIS. I CALLED THE DEALERSHIP, AND THEY WERE UNCERTAIN AS HOW TO HELP. I'M VERY CONCERNED THAT I WILL CRASH INTO SOMEONE OR GO THROUGH AN INTERSECTION BECAUSE OF THE RELEASE OF THE BRAKE. *TR

I OWN A 2010 TOYOTA PRIUS AND HAVE HAD MY CAR IN FOR SERVICE TO ADDRESS THE BRAKE RECALL. HOWEVER, TODAY I DROVE OVER A POTHOLE AND THE SYMPTOM OF THE RECALL (LOSS OF BRAKING POWER) OCCURRED. THIS HAS HAPPENED ONE OTHER TIME IN THE PAST FEW DAYS SINCE I HAVE BROUGHT MY CAR IN FOR THE RECALL SERVICE. THE SERVICE APPEARS NOT TO HAVE ADDRESSED THE PROBLEM. *TR

S10 APPROPRIATE HANDLING RE BRAKING PROBLEMS EXPERIENCE BY AN OWNER OF A 2010 TOYOTA PRIUS. *KB THE CONSUMER STATED HE EXPERIENCED INCONSISTENT BRAKING WHILE DRIVING ON WET, BUMPY ROADS WHICH REQUIRED EXTRA VIGILANCE AS THE FEEL OF THE BRAKES WOULD OFTEN CHANGE. THE CONSUMER ALSO STATED THE PROBLEM WAS ALSO EVIDENT WHILE IN REVERSE. UNFORTUNATELY, THE VEHICLE DID NOT STOP WHILE IN REVERSE AND HIT ANOTHER CAR. THE CONSUMER'S VEHICLE AS WELL AS THE OTHER VEHICLE WERE DAMAGED. THE CONSUMER STATED HIS VEHICLE IS CURRENTLY AT THE DEALERSHIP RECEIVING THE SOFTWARE UPGRADE TO SUPPOSEDLY ADDRESS THE BRAKING PROBLEM. *JB

DRIVING MY 2010 PRIUS TOWARDS A TRAFFIC LIGHT. LIGHT TURNS FROM ORANGE TO RED AND I BRAKE IN PLENTY OF TIME. SMALL POTHOLE JUST AS I STOP MAKES THE CAR'S BRAKE "SLIP" AND I SHOOT FORWARD SEVERAL FEET. I NOW UNDERSTAND WHAT THE BRAKING PROBLEM IS PEOPLE HAVE BEEN TALKING ABOUT. *TR

BRAKE FAILURE WHEN DRIVING AT SLOW SPEEDS OVER BUMPY SURFACE. 2010 TOYOTA PRIUS. *TR

WHILE BRAKING ON A SHORT HILL WITH UNEVEN PAVEMENT SURFACE VEHICLE BRAKES FAILED MOMENTARILY AND THEN TOOK HOLD AS I PRESSED HARDER ON THE PEDAL. THIS OCCURRED 3 TIMES ON THE SAME HILL. *TR

I HAVE A 2010 TOYOTA PRIUS. WHEN DEPRESSING THE BRAKE PEDAL WITH PRESSURE, IT GOES ALL THE WAY TO THE FLOOR AND THE WARNING LIGHT THAT YOU ARE SKIDDING ILLUMINATES. I HAVE ONLY TESTED THIS AT TRAFFIC LIGHTS AND NOT WHILE MOVING. I HAD THE PRIUS IN FOR AN OIL CHANGE IN GASTONIA, NC AND THEY SAID THEY FIXED THE PROBLEM BUT IT STILL HAPPENS. *TR

WE BOUGHT A 2010 PRIUS LAST JULY. SINCE BUYING THE PRIUS WE HAVE HAD THE BRAKES COMPLETELY STOP WORKING, DURING BRAKING AFTER DRIVING OVER A SMALL BUMPS (MANHOLE COVER, DISTURBED PAVEMENT, SMALL POTHOLE). THIS HAS NOW HAPPENED AROUND 10 TIMES. FORTUNATELY, AFTER COMPLETELY RELEASING THE BRAKES WOULD AGAIN BRAKE AFTER APPLYING INCREASED PRESSURE ON THE BRAKE PEDAL. MOST RECENTLY THE BRAKING FAILURE OCCURRED THE DAY IMMEDIATELY FOLLOWING HAVING THE 'BRAKE RECALL" MAINTENANCE PERFORMED BY TOYOTA TO CORRECT THE BRAKING PROBLEM. THE "FIX" IS OBVIOUSLY NOT CORRECTING THE PROBLEM. THIS IS A MAJOR SAFETY CONCERN. THE BRAKES ONCE GAVE OUT WHILE APPROACHING A PEDESTRIAN IN A CROSSWALK. IT IS ONLY A MATTER OF TIME BEFORE SOMEONE IS SERIOUSLY INJURED OR WORSE. PLEASE HELP. WHAT SHOULD I DO NOW? *TR

2010 PRIUS BRAKES. AFTER MY FIRST COMPLAINT AND ALL THE NEWS ON THIS PROBLEM I HAVE BEEN PAYING CLOSE ATTENTION AND AS I FIRST THOUGHT THE CAR DOES NOT JUST LOOSE BRAKING IT ACTUALLY ACCELERATES. WHEN BRAKING OVER ROUGH SURFACES OR POTHOLES AND YOUR FOOT ON THE BRAKE PEDAL YOU FEEL THE CAR SPEED UP FOR MAYBE ONE OR TWO SECONDS. SO FAR I HAVE BEEN ABLE TO STOP OK. I QUICKLY LET OFF THE BRAKE PEDAL AND REAPPLY THEM AND EVERYTHING STOPS FINE. I GET NO WARNING LIGHTS OR ALARMS AND NEVER KNOW WHEN IT MIGHT HAPPEN. STOPPING OVER THE SAME SURFACE THE NEXT DAY MAY NOT PRODUCE THE SAME RESULTS, PRETTY RANDOM PROBLEM. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT AS SHE WAS COMING TO A STOP AND THE ROAD WAS WET WHEN THERE WAS GRAVEL ON THE ROAD THE BRAKES WOULD NOT ENGAGE WHILE BEING DEPRESSED. THE VEHICLE LUNGED FORWARD AND HIT THE CURB A COUPLE OF TIMES. WHEN DRIVING AT A HIGH SPEED AND SLOWING DOWN THE BRAKES DID NOT HOLD AND A CRASH ALMOST OCCURRED. THE CONTACT STATED THAT ON SEVERAL OCCASIONS BRAKE FAILURE OCCURRED SINCE THE VEHICLE WAS PURCHASED. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THAT THE FAILURE WAS NOT RELATED TO THE BRAKES BUT HOW SHE DROVE THE VEHICLE. THE TOYOTA MANUFACTURER HAVE NOT BEEN CALLED FOR THE FAILURE. THE FAILURE MILEAGE WAS 14,905.

I HAVE A 2010 TOYOTA PRIUS MODEL V WITH THE ADVANCED TECHNOLOGY OPTION INCLUDING PCS (PRE-COLLISION SYSTEM) SYSTEM. TWICE IN THE LAST 6 WEEKS THE PCS SYSTEM HAS TRIGGERED WHILE I HAVE BEEN DRIVING. AT THIS TIME I DID NOT HAVE THE RADAR CONTROLLED CRUISE CONTROL ON OR ENGAGED. BOTH TIMES, THE SEATBELTS RAPIDLY RETRACTED THE CAR STARTED BRAKING RAPIDLY AND BEEPING AGGRESSIVELY. BOTH TIMES AFTER WHAT SEEMED LIKE 3-5 SECONDS THE CAR RETURNED TO NORMAL DRIVING. BOTH TIMES I WAS DRIVING AT NIGHT AT SPEEDS BETWEEN 35 AND 55 MPH. BOTH TIMES DUE TO THE RAPID SEATBELT/SHOULDER BELT RETRACTION MY LEFT ARM AND CHEST WAS HURT. THE PAIN LASTS ABOUT A WEEK, SO THERE WAS A SERIOUS BRUISE WHICH WOULD HAVE BEEN OK IF THERE WAS REALLY A CRASH SITUATION. BOTH TIMES THERE WAS NO ONE IN FRONT OF ME. ONCE THERE WAS SOMEONE BEHIND ME WHO ALMOST CRASHED INTO ME BECAUSE OF THE RAPID BRAKING. *TR

TL*THE CONTACT HAS A 2010 TOYOTA PRIUS. A CRASH OCCURRED WHEN THE BRAKES FAILED TO STOP THE VEHICLE. THE CONTACT STATED THAT HE APPLIED PRESSURE TO THE BRAKE PEDAL TO NO AVAIL. THE VEHICLE WAS TRAVELING 15 MPH AT THE TIME OF THE FAILURE. THE WEATHER CONDITIONS WERE A FACTOR AND THE ROAD WAS COVERED WITH SNOW AND ICE AT THE TIME. THE CURRENT AND FAILURE MILEAGE WAS 8,000. UPDATED 06/28/10*JB

PRIUS, WHEN BRAKE WAS DEPRESSED IT SPED UP WHEN DRIVING SLOW AND HITTING A POT HOLE THIS HAPPENED TWICE BEFORE TOYOTA CAME OUT WITH THE INFORMATION ABOUT THE BRAKES AND ONCE SINCE THE INFORMATION HAS BEEN IN THE NEWS. I BOUGHT THE CAR IN AUGUST HAD THE FIRST INCIDENT IN SEPT. ONE AROUND CHRISTMAS AND ONE THIS MONTH. DIDN'T REALLY KNOW WHAT WAS HAPPENING UNTIL NOW. *TR

I BOUGHT A 2010 PRIUS IN NOVEMBER OF 2009. I SOON DISCOVERED THAT THE CAR WOULD NOT BRAKE PROPERLY AND A COUPLE OF MONTHS LATER HEARD ABOUT THIS ISSUE ON THE NEWS. I BROUGHT MY CAR IN FOR THE RECALL AND A SOFTWARE PATCH WAS APPLIED TO THE CAR TO RECTIFY THE SITUATION. THAT WAS 5 DAYS AGO. UPON LEAVING THE DEALERSHIP, THE CAR DID FEEL BETTER; THE BRAKES DID NOT FEEL AS SENSITIVE. HOWEVER, IN THE PAST FIVE DAYS I HAVE EXPERIENCED THE SAME EXACT SENSATION OF THE CAR NOT BRAKING WHEN I HAVE BEEN RIDING OVER A ROUGH PATCH OF ROAD AT A SPEED OF LESS THAN 30 MPH. BUT IT'S NOT JUST A FEELING. THE CAR SURGES FORWARD MOMENTARILY. IT ALMOST FEELS LIKE I AM SKIDDING ON ICE. I DO NOT FEEL SAFE IN THIS VEHICLE DESPITE THE FACT THAT THE FOLKS AT MY TOYOTA DEALERSHIP SAID THIS PROBLEM WAS "NOT A SAFETY ISSUE." I DISAGREE. I AM AFRAID THAT I WILL LOSE BRAKING ABILITY AND HIT SOMETHING OR SOMEONE OR END UP IN AN INTERSECTION INVOLUNTARILY. I HAVE A FIVE YEAR OLD DAUGHTER. I REALLY WANT MY MONEY BACK. I WOULD NEVER HAVE PURCHASED THIS CAR IF I HAD KNOWN IT HAD FAULTY BRAKES. I FEEL BURNED BY TOYOTA. *TR

2010 TOYOTA PRIUS: HAD THE CAR FOR SEVERAL MONTHS AND REALLY ENJOY DRIVING IT...OKAY, I LIKE THE MILEAGE, IT'S NOT A CORVETTE THOUGH. HAVE NOTICED ON ROUGH PAVEMENT AND POTHOLES THAT THE BRAKES DO SEEM TO GIVE A LITTLE. HOWEVER ON 19 FEB 10 I HIT THE BRAKES TO STOP AND IT FELT LIKE THE SIMPLY MADE A GRINDING SOUND AND BARELY SLOWED AT ALL...THE HARDER I PRESSED THE LESS THE SEEMED TO APPLY. THESE CARS ARE DANGEROUS AND SHOULD BE REMOVED FROM THE ROADS UNTIL TOYOTA FIXES THIS AND PROVES THE PROBLEM IS CORRECTED...I WILL NOT DRIVE IT UNTIL THEY DO SO... *TR

2010 TOYOTA PRIUS WITH BRAKE PROBLEM. CONSUMER STATES THAT A SUDDEN LOSS OF BRAKING OCCURS AFTER DRIVING OVER SMALL POTHOLES, LOOSE GRAVEL, OR DOWN A SLIGHT HILL. *KB THE CONSUMER STATED IT FELT AS THOUGH THE VEHICLE WAS ACCELERATING FOR 1-3 SECONDS. *JB

2010 TOYOTA PRIUS SOFTWARE DEFECT IN THE ENGINE CONTROL SYSTEM. CONSUMER STATES WHILE REVERSING BEFORE THE START UP OPERATION IS COMPLETE THE BRAKES GRAB. *KB THE CONSUMER PARKED FACING AN UPSLOPE AT THE DEALER TO GET HIS LICENSE PLATE INSTALLED. TO LEAVE, THE CONSUMER PUT HIS FOOT ON THE BRAKE AND PRESSED THE POWER BUTTON. AS THE DASHBOARD STARTED TO LIGHT UP, HE SHIFTED INTO REVERSE, RELEASED THE PARKING BRAKE AND THE FOOT BRAKE AND STARTED TO EASE DOWN THE RAMP. AS THE CONSUMER APPLIED THE FOOT BRAKE, THE BRAKES GRABBED BADLY. THE CONSUMER RELEASED AND RE-APPLIED THEM, AND AGAIN THEY GRABBED. THE GRABBING WAS SEVERE ENOUGH THAT THE VEHICLE WAS NOT SAFE TO DRIVE AND THE CONSUMER JUST STOPPED. THE CONSUMER BELIEVED THE BEHAVIOR INDICATED A DEFECT IN THE SOFTWARE THAT CONTROLLED THE START-UP SEQUENCE. THE CONTROL COMPUTER SHOULD NOT ALLOW THE VEHICLE TO BE SHIFTED INTO DRIVE OR REVERSE UNTIL THE POWER-ON OPERATIONS HAVE BEEN FULLY COMPLETED. *JB

THIS IS AN UPDATE TO AN EARLIER COMPLAINT (#10304111). WE HAD AN ACCIDENT WITH OUR 2010 TOYOTA PRIUS WHICH WE FIRMLY BELIEVE WAS CAUSED BY BRAKE FAILURE. MY WIFE WAS DRIVING THE CAR ON A SLIPPERY ROAD, IT WAS LIGHTLY SNOWING, AT ABOUT 10-15 MPH AND CAME TO A STOP SIGN. SHE APPLIED THE BRAKES AND SAID NOTHING HAPPENED. AS A CAR WAS AT THE STOP SIGN SHE TURNED TO AVOID THE CAR AND HIT A RAISED AND SHARP CURB, WHICH PIERCED THE TIRE AND BENT THE TIE-ROD. OUR CAR WAS TOWED TO A BODY SHOP. AFTER ABOUT 10 DAYS, STATE FARM INSPECTED THE CAR, BUT BY THIS TIME THE RECALL FOR THE PRIUS HAD BEEN ANNOUNCED. THE BODY SHOP THEN REFUSED TO FIX THE CAR AND WE HAD TO TAKE IT TO A TOYOTA DEALER. STATE FARM HAS SINCE DECIDED NOT PURSUE THIS INCIDENT AS THEY FEEL THE SNOW CAUSED THE ACCIDENT AND THAT THE TEMPORARY LOSS OF BRAKES IS NOT WHAT THE RECALL IS ABOUT. FROM OUR READING OF NUMEROUS ARTICLES (NY TIMES) AND THE RECALL INFORMATION ITSELF, PLUS WHAT HAPPENED, WE ARE STRONGLY STATING THAT THERE WAS IN FACT A TEMPORARY OR MOMENTARY LOSS OF THE BRAKES WHICH DIRECTLY CAUSED THIS ACCIDENT. FROM OUR READING OF THE RECALL AND OTHER COMPLAINTS, SLIPPERY CONDITIONS ARE ONE OF THE FACTORS WHICH CAUSE THIS PROBLEM. IN OUR CASE, THIS PROBLEM WAS EXACERBATED AS NOT ONLY WAS THERE SLIPPERY CONDITIONS, BUT THE CAR WAS ON A HILL AS WELL. WE HAVE ALSO EXPERIENCED PRIOR TO THIS ACCIDENT A SKIPPING OR MOMENTARY BRAKE PROBLEM WHEN GOING OVER BUMPY ROADS. WHEN ASKING ABOUT THIS WE WERE ALWAYS TOLD IT HAD TO DO WITH THE ABS SYSTEM AND THAT IT WAS NORMAL. WELL THE RECALL PROVES THIS WAS NOT NORMAL AND NOW WE'VE EXPERIENCED THE PROBLEM ON SLICK ROADS AS WELL -- WHICH HAS NOW COST US MONEY. *TR

TWO FAILURES. FIRST WHILE TRAVELING AT HIGH SPEED FROM CANADA TO NYC ON DECEMBER 26, THE LEFT SIDE OF MY ELECTRONIC DISPLAY WENT OUT, SPECIFICALLY THE SPEEDOMETER AND GAS MILEAGE COMPONENT OF THE DISPLAY BLANKED OUT. IT TOOK TOYOTA ABOUT A WEEK TO FIGURE OUT HOW TO FIX IT. SECONDLY, I BROUGHT MY 2010 PRIUS INTO MY LOCAL DEALER BECAUSE OF THE BRAKING ACCELERATION ISSUE. IT HAD HAPPENED ABOUT 10 TIMES SINCE I BOUGHT THE CAR ON JUNE 30, 2009. AS THE CAR WAS BRAKING TO A STOP, THERE SEEMED TO BE AN ACCELERATION ASSOCIATED WITH THE BRAKING. WHEN I BROUGHT IT TO STAR TOYOTA OF BAYSIDE, THEY HAD THE TECHNICIAN DRIVE THE CAR FOR ABOUT 3 MILES AND STATED THAT THEY FOUND NO TROUBLE. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHENEVER SHE WAS APPLYING THE BRAKES, THE BRAKES CEASE TO WORK PERIODICALLY WHEN GOING OVER A BUMP OR A POT HOLE. THE VEHICLE LURCHES FORWARD AS THE BRAKES ARE DEPRESSED WHENEVER SHE HITS A BUMP. THE VEHICLE WAS TAKEN TO THE DEALER AND CONTACT WAS TOLD IT WAS HER IMAGINATION AND NOTHING IS WRONG WITH THE BRAKES. THE TOYOTA MANUFACTURER HAD NOT BEEN CALLED AT THE TIME OF THE COMPLAINT. THIS FAILURE HAS HAPPENED FROM THE DAY OF PURCHASE . UPDATED 03/15/10 *BF THE CONSUMER STATED WHEN THE BRAKES WERE DEPRESSED OCASSIONALLY, THE BRAKING MECHANISM WOULD FAIL MOMENTARILY WHICH CAUSED THE VEHICLE TO LUNGE FORWARD . THE CONSUMER HAD REPAIRS MADE TO THE VEHICLE. HOWEVER, THE PROBLEM CONTINUED. UPDATED 09/15/10

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. SHE STATED THAT WHILE DRIVING AT 30 MPH SHE DROVE OVER A BUMP ON THE ROAD. WHILE HAVING HER FOOT ON THE BRAKE THE VEHICLE SURGED FORWARD, A FEW SECONDS LATER THE BRAKES ENGAGED. THIS ISSUE HAS OCCURRED 5 ADDITIONAL TIMES. THE VEHICLE HAS NOT BEEN DIAGNOSED AND NO REPAIRS HAD BEEN DONE AT THE TIME OF THE COMPLAINT. THE FAILURE MILEAGE WAS 1000 AND CURRENT MILEAGE WAS 35000.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS HYBRID. WHILE DRIVING APPROXIMATELY 2 MPH, THE BRAKES WERE APPLIED AND THEY DID NOT ENGAGE. THE CONTACT CALLED TOYOTA AND WAS ADVISED TO WAIT FOR A LETTER. THE CONTACT CALLED THE MANUFACTURER AND COULD NOT GET THROUGH. THE CURRENT MILES WERE 3603. THE FAILURE MILES WERE 1689.

PRIUS 2010 - WHEN I BRAKE GOING OVER POTHOLE, THERE IS A SUDDEN ACCELERATION. THIS HAPPENED TWICE SINCE I BROUGHT THE CAR IN TO THE TOYOTA DEALERSHIP AND THEY CLAIMED THEY "FIXED" THE PROBLEM. IT HAPPENED MOST RECENTLY TODAY MONDAY FEBRUARY 22, 2010. *TR

I HAVE HAD SEVERAL PROBLEMS WITH MY 2010 TOYOTA PRIUS. I HAVE FOUND THE BRAKES TO BE UNDEPENDABLE IN SITUATIONS OF UNEVEN PAVEMENT OR ANYTHING BUT PERFECT ROAD CONDITIONS. AFTER APPLYING THE BRAKES, THE CAR CONTINUES TO MOVE FORWARD AS IF THE BRAKES WERE NEVER APPLIED. THIS CONTINUES FOR SEVERAL SECONDS CAUSING A DANGEROUS DELAY IN PERFORMANCE OF THE BRAKES. THIS HAS OCCURRED SEVERAL TIMES THIS WINTER, AND IS UNFORTUNATELY NOT PREDICTABLE. ONE INSTANCE LED TO MY CAR SLAMMING INTO AN SNOW AND ICE BANK DAMAGING THE LOWER FRONT PART OF THE CAR. ANY OTHER CAR I HAVE DRIVEN WOULD HAVE STOPPED LONG BEFORE HAVING CONTACT WITH THE BANK, AS THE PAVEMENT WAS DRY YET UNEVEN. ANOTHER ISSUE I HAVE HAD IS UNRELIABLE ACCELERATION, AGAIN A HESITATION OF SEVERAL SECONDS AFTER THE ACCELERATOR PEDAL IS PUSHED THAT IS DANGEROUS AS WELL MAKING PERFORMANCE UNPREDICTABLE. BOTH THESE SITUATIONS LEAVES ME UNCERTAIN OF WHAT KIND OF PERFORMANCE I CAN EXPECT FORM BOTH THE BRAKES AND ACCELERATOR AT ANY GIVEN TIME. SINCE I DRIVE MY DAUGHTER TO SCHOOL EACH DAY, I AM NERVOUS EVERY TIME I GET INTO THE CAR AND CONCERNED ABOUT THE SAFETY OF MY DAUGHTER AND THE OTHER STUDENTS. I ALSO REGULARLY WAKE UP IN THE MIDDLE OF THE NIGHT FEARFUL ABOUT DRIVING MY PRIUS TO SCHOOL AND WORK THE FOLLOWING DAY. SO FAR I HAVE DONE NOTHING TO CORRECT THE SITUATION AS TOYOTA DEALERSHIPS ARE SO SWAMPED BY OTHER RECALL APPOINTMENTS THAT IT IS NEARLY IMPOSSIBLE TO GET AN APPOINTMENT FOR ANYTHING BUT A RECALL. SO FAR TOYOTA HAS NOT CONTACTED ME ABOUT THE BRAKE RECALL SOLUTIONS OR RECALL PROCESS, SO I AM AT A LOSS ABOUT WHERE TO TURN. *TR

BRAKE FAILURE ON 2010 PRIUS IN SNOWY CONDITIONS. I WAS DRIVING WITH MY 11 YEAR OLD DAUGHTER GOING LESS THAN 10 MILES PER HOUR APPROACHING A BUSY INTERSECTION. THE BRAKES WOULD NOT ENGAGE AND I COULD NOT STOP BEFORE ENTERING THE INTERSECTION. I WAS ALMOST HIT BY A BUS. THE BUS SAW ME AND SPED UP THUS AVOIDING A TRAGEDY. ALSO, THE OTHER ONCOMING TRAFFIC WAS ABLE TO STOP AND AVOID ME. MY DAUGHTER AND I WERE VERY FORTUNATE. I AM HORRIFIED AND WANT THIS CORRECTED. *TR

DURING BRAKING, MY 2010 TOYOTA PRIUS WOULD "LUNGE" FORWARD AS THOUGH THE BRAKES DID NOT WORK FOR A FEW SECONDS WHEN "HITTING" SMALL BUMPS IN THE ROAD. THIS HAPPENED TWICE. *TR

I HAVE 2010 PRIUS. I AM EXPERIENCING AN ENERGY SURGE FROM MY BACK WHEELS WHEN I STEP ON MY BRAKES WHILE SIMULTANEOUSLY GOING OVER A BUMPY SURFACE LIKE RAIL ROAD TRACKS, POT HOLE OR ROUGH GROUND. IT OCCURS SEVERAL TIMES A WEEK. THE RESULT IS THAT MY CAR SUDDENLY SPEEDS FORWARD WHEN I LEAST WANT IT TO - I AM BRAKING. I HAVE IT THRUST ME INTO AN INTERSECTION. I REPORTED IT TO MY SERVICE DEPT IN NOV 09. THEY TOLD ME THEY HAD NEVER HEARD OF THIS PROBLEM BEFORE AND HAD NO OTHER COMPLAINTS. WITH A FRONT WHEEL DRIVE I DIDN'T UNDERSTAND WHY THE POWER SEEMED TO BE COMING FROM THE BACK WHEELS. NOW I AM ASSUMING IT IS SOME KIND OF CONNECTION TO THE ABS SYSTEM. THIS HAPPENS MOST NOTABLY AT LOWER SPEEDS, ROUNDING A CORNER. BUT I THINK IT MAY ALSO BE HAPPENING ON THE HIGHWAY, BUT THE SURGE IS HARDER TO DETECT AT HIGHER SPEED. *TR

TL*THE CONTACT HAS 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 15 MPH FOUR TIMES WHEN SHE DROVE OVER A POTHOLE AND THE BRAKES WERE APPLIED, IT FELT AS IF THE VEHICLE LUNGED FORWARD. THE BRAKES ALWAYS FUNCTIONED NORMALLY ON EVEN ROAD SURFACES VS. AN UNEVEN SURFACE. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 2500. THE CURRENT MILEAGE WAS 2700.

I WAS BRINGING MY 2010 PRIUS TO A STOP AT A STOPSIGN ON E BOUND MLK DRIVE IN SAN FRANCISCO'S GOLDEN GATE PARK THE EVE OF 2/15/10. THE PAVEMENT WAS BUMPY, AND THE BRAKES "SKIPPED" FOR A HALF-SECOND. I WAS ABLE TO BRING THE CAR TO A SAFE AND COMPLETE STOP WITHOUT HAZARD, EXCEPT FOR A MOMENTARY JUMP IN MY HEART RATE. *TR

I WAS DRIVING MY 2010 TOYOTA PRIUS (WHICH I PURCHASED IN JULY OF 2009) AROUND 6:30 PM WEDNESDAY JAN. 27TH 2010 IN AN AREA WITH MANY TRAFFIC LIGHTS. THE TEMPERATURE WAS BELOW FREEZING. I WAS GOING BETWEEN 25 - 30 MPH AND I WAS FOLLOWING TWO OTHER VEHICLES AT A SAFE DISTANCE. THE VEHICLE IN FRONT OF ME CAME TO A SUDDEN STOP IN RESPONSE TO THE VEHICLE IN FROM OF HIM STOPPING SUDDENLY FOR A RED LIGHT AT A TRAFFIC LIGHT. I HIT MY BRAKES AND IT FELT AS IF THERE WAS A MOMENTARY PAUSE BEFORE THE BRAKES ENGAGED. I HIT THE VEHICLE IN FRONT OF ME AT LESS THAN 5 MPH. THE ACCIDENT CAUSED DAMAGE TO THE HOOD AND FRONT END OF MY VEHICLE. THE VEHICLE IN FRONT OF ME WAS A SUV SO I CAUSED ONLY SLIGHT DAMAGE TO HIS REAR BUMPER (THE FRONT END OF MY CAR WENT UNDER HIS BUMPER). I WAS FOLLLOWING AT A SAFE DISTANCE AND FEEL THAT THE MOMENTARY PAUSE FROM THE TIME I HIT MY BRAKE PEDAL TO THE BRAKES ENGAGING CAUSED ME TO BUMP INTO THE VEHICLE IN FRONT OF ME. *TR

I WAS DRIVING MY 2010 TOYOTA PRIUS ON A SNOW COVERED, ROUGH RESIDENTIAL STREET. WHILE TURNING INTO A DRIVEWAY TO TURN AROUND TO GRAB A PARKING SPOT, I APPLIED THE BRAKES AND THEY COMPLETELY RELEASED AND I SLAMMED TO THE SNOW PILED AT THE ENTRANCE TO THE DRIVEWAY. THE FRONT BUMPER COVER GOT A HOLE PUNCHED INTO IT THE SIZE OF A BASEBALL FROM THE FROZEN SNOW. SINCE THEN THE BRAKES HAVE RELEASED WITHOUT INCIDENT BUT NOT WITHOUT CONCERN. I CALLED AND REPORTED THE PROBLEM TO MY TOYOTA DEALER AND HE ASKED "DO I HAVE AN ERROR SHOWING UP ON THE DASH SCREEN" AND I SAID "NO". I ASKED WAS THERE A NEW UPDATED PROGRAM AND HE SAID HE DID NOT KNOW ANYTHING ABOUT IT AND THEY DON'T HAVE A FIX ANYWAY. THIS WAS BEFORE THE CAR WAS RECALLED BY A COUPLE OF WEEKS BUT AFTER TOYOTA HAD STARTED LOADING A DIFFERENT PROGRAM ONTO THE CAR. ON FEB. 17, 2010 TOYOTA DID FLASH THE CAR'S COMPUTER TO FIX THE PROGRAM ISSUES. I WOULD LIKE TOYOTA TO HAVE THE FRONT BUMPER COVER REPAIRED. THANKS. *TR

WHEN BRAKING IF MY CAR HITS A BUMP MY BRAKES DISENGAGE. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE THE CONTACT WAS DRIVING AT 15 MPH THERE WAS A REDUCTION OF THE SPEED RATE. THE DRIVER ENCOUNTERED A SPEED BUMP WITH PRESSURE OF THE FOOT APPLIED TO THE BRAKE PEDAL. THE BRAKES FAILED TO ENGAGE AND THE VEHICLE BEGAN TO SURGE FORWARD. THE VEHICLE CONTINUED TO THE DESTINATION AND PARKED THE VEHICLE. THE FAILURE OCCURRED TWO DIFFERENT TIMES. THE CONTACT IS IN THE PROCESS OF NOTIFYING THE DEALER. THE VEHICLE HAS NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 3000 AND CURRENT MILEAGE WAS 5000.

INTERMITTENTLY, WHILE I AM BRAKING WHEN APPROACHING AN INTERSECTION THE CAR WILL MOMENTARILY ACCELERATE QUICKLY. WITH PRESSURE ON THE BRAKE THE CAR THEN SLOWS. THIS HAS HAPPENED ABOUT 6 -10 TIMES SINCE I BOUGHT THE CAR IN SEPT. 2009. *TR

2010 PRIUS PURCHASED IN AUGUST 2009. SURGE WHEN APPLYING BRAKES. OCCURRED 4 TIMES INCLUDING 2/15/2010. HAS OCCURRED IN SAME PLACE 3 TIMES. EACH TIME THERE WERE POTHOLES. WHEN THEY WERE FIXED, DID NOT HAPPEN UNTIL THEY RETURNED. COMPLAINED TO TOYOTA DEALER AND WAS TOLD THIS WAS NORMAL WHEN HYDRAULIC AND ELECTRONIC BRAKES EXCHANGE. I SUGGESTED IT WAS A DANGEROUS NORMAL. NO DAMAGE OR INJURY IN ANY CASE. WAS ALWAYS ABLE TO PUSH HARDER ON BRAKE TO STOP CAR. STUNS YOU WHEN IT HAPPENS BECAUSE IT IS NOT NORMAL. SINCE FIRST INSTANCE, HAVE TRIED TO KEEP DISTANCE WHEN SLOWING AND BRAKING. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS WHICH WAS PURCHASED IN AUGUST 2009. SHE STATED THAT WHENEVER SHE APPLIED THE BRAKE PEDAL DURING INCLEMENT OR RAINY WEATHER CONDITIONS AND UNEVEN PAVEMENT, THE VEHICLE LUNGED FORWARD. THE BRAKES WOULD NOT ENGAGE AND THERE WOULD BE A MOMENTARY HESITATION. THE DEALER WAS CONTACTED AND ADVISED HER THAT IT WAS NORMAL AND SHE MUST HAVE BEEN DRIVING TOO FAST. THE CONTACT CONFIRMED SHE WAS NOT SPEEDING AND THAT EVEN WHILE TRAVELING AT SPEEDS OF LESS THAN 10 MPH OR IN A PARKING LOT, THE FAILURE WOULD OCCUR. THE ECU MODULE AND THE ABS SYSTEM WAS REPROGRAMMED UNDER THE SERVICE BRAKES RECALL CAMPAIGN ID NUMBER: 10V039000. THERE WERE NO ADDITIONAL FAILURES SINCE THE REPAIR WAS MADE. THE FAILURE MILEAGE WAS 200 AND THE CURRENT MILEAGE WAS 5,000.

WE HAVE A VERY LONG STEEP DRIVEWAY. I APPLY SOME BRAKING WHEN DESCENDING AND THEN MORE AS I REACH THE BOTTOM BEFORE I ENTER THE STREET. THERE IS A WATER DIVERTER BUMP ABOUT TEN FEET BEFORE THE END OF THE DRIVEWAY. IT IS ABOUT AN INCH OR SO TALL AND ABOUT SIX INCHES WIDE, CROSSING THE FULL WIDTH OF THE DRIVEWAY. SEVERAL TIMES WHEN I HAVE ROLLED OVER THE BUMP AND I AM APPLYING MORE BRAKES, THE BRAKES STOP WORKING FOR A SECOND OR SO AND THEN REGAIN POWER. AT FIRST IT FELT LIKE I WAS ACCELERATING, UNTIL IT HAPPEN A SECOND TIME AND I WAS MORE AWARE OF WHAT WAS GOING ON. APPLYING HEAVIER BRAKING BEFORE THE BUMP, SEEMS TO STOP THIS SENSATION. THE LAST TIME THE BRAKES DID THIS WAS WHEN PULLING TO THE SIDE OF THE ROAD TO LET FASTER TRAFFIC BY, ONTO A ROUGH GRAVEL DRIVEWAY ENTRANCE. INITIALLY THE BRAKES WORKED THEN FOR AN INSTANT THEY ARE GONE, THEN BACK AGAIN. BEFORE THE RECALL WE CALLED THE DEALER WHO SAID WE WERE JUST NOT USED TO ANTI LOCK BRAKES! WE HAVE HAD ANTI LOCK BRAKES FOR MANY MANY YEARS IN MANY DIFFERENT VEHICLES. WE KNOW WHEN THE ANTI-LOCK BRAKES ARE DOING THEIR JOB. THIS IS NOT THE SAME TYPE OF PULSING UPON HEAVY BREAKING. THIS HAPPENS IN THE 2010 PRIUS WHEN USING NORMAL BRAKING PRESSURE. *TR

MY 2010 PRIUS HAS EXPERIENCED THE BRAKING ISSUE WHEN GOING OVER A BUMP OR A POTHOLE. *TR

BRAKES ON MY PRIUS HAVE MOMENTARILY FAILED ON TWO OCCASIONS - BOTH TIMES HAPPENED AFTER GOING OVER A POT HOLE/ROUGH PATCH OF ROAD. *TR

ANTI LOCK BRAKES DO NOT WORK PROPERLY CAR JUMPS WHEN HITTING AN UNEVEN ROADWAY WHEN APPLING BRAKES. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED UNDER NORMAL CONDITIONS AS SHE WAS DRIVING AT 45MPH AND COMING TO A STOP WITH HER FEET ON THE BRAKES THE VEHICLE LUNGED FORWARD BEFORE STOPPING. THE CONTACT CALL THE DEALER AND INFORM THEM OF THIS AND WAS TOLD THERE IS NO PROBLEMS WITH THE VEHICLE AND THEY NEVER HEARD OF THIS FAILURE. THERE HAD BEEN NO PRIOR MAINTENANCE PERFORMED ON THE VEHICLE PRIOR TO THE FAILURE. THE FAILURE MILEAGE WAS 1,500.

TEMPORARY LOSS OF BRAKING ON 2010 TOYOTA PRIUS ON UNEVEN PAVEMENT. ONE OCCURRENCE ON 10/20/2009. AN EARLIER OCCURRENCE ALSO OCCURRED ON UNEVEN PAVEMENT - PROBABLY IN SEPTEMBER 2009, BUT I DO NOT HAVE A RECORD OF THE DATE. THE DEALERSHIP PERFORMED THE RECALL MAINTENANCE TODAY (02/16/2010). PLEASE NOTE THAT THE CAR ALSO EXHIBITS EXTREME BRAKING IMMEDIATELY AFTER A COLD START UNDER WET CONDITIONS. THIS EXTREME BRAKING IS UNLIKE ANY OTHER CARS PREVIOUSLY OWNED OVER NEARLY 40 YEARS. THE EXTREME BRAKING DOES SUBSIDE AFTER A SHORT DISTANCE IF THE BRAKES ARE LIGHTLY APPLIED WHILE DRIVING ACCELERATOR IS DEPRESSED TO MAINTAIN SPEED. *TR
