2018 Honda Accord Collision Avoidance Problems

Upwards of a dozen times my Honda Accord will suddenly brake as it believes I am about to have a collision whereas it is typically a shadow. This happens when going under bridges or overpasses, or depending on the glare from the sun. This has happened several times on the highway causing multiple near collisions at high speeds.

I was driving on a four-lane highway using adaptive cruise control, gaining on a vehicle ahead. When the cruise control picked up the vehicle, I accelerated slightly, used left turn signal and began changing lanes, the warning for collision mitigation came on and the cruise control disengaged. Continued driving home and the warning continued, and cruise control would not function.

I will be driving and automatically it will lock the brakes and nobody will be in front of me. I tried turning it off but somehow it still ends up on. This has been doing it now for some but it’s getting worse and worse.

Emergency Braking System engaged for no apparent reason with no other vehicles on the road. Potential for rear-end collision. This was the first event.

While traveling at approximately 30-35 MPH, my vehicle suddenly and abruptly stopped, flashing the word "brake" on my dashboard. I was traveling in the right lane on a four lane road, with no vehicles in front of me or to the left of me. There were no pedestrians near, the road was free from any hazards and the road ahead was clear of any potential hazards that may require an abrupt halt.

Collision Mitigation automatically engaged causing vehicle to brake when unnecessary. Once after excelling from a redlight and again when entering a highway on ramp. After occurring twice in a 6 month period it's now become permanently disabled with dash warnings.

Road departure mitigation cruise control collision mitigation emission systems not working when I drive my car it stalled

Every week the following warning lights keep coming on, brake System problem, vehicle stability assist, electric power steering system, hill start assist, acc, collision mitigation. And engine light. Has happened 6 times since purchase.

yes it is available for inspection. car all of a sudden puts on its brakes could have caused a rear end accident not on my car no they come on and go off randomly it started acting up and then the lights came on

My collision mitigation braking system is automatically braking on me with nothing in front of me going high rated speeds on the interstate. I have chronic migraines and neck issues that also have been being treated on a very consistent basis. I brought it in numerous times.

My 2018 Honda According Touring 1.5 Liter Turbo has an intermittent problem with the vehicle’s warning alerts. The vehicle systems affected include Adaptive Cruise Control, Vehicle Emission System, Tire Pressure Monitoring System, Vehicle Stability Assistance, Hill Start Assist, Braking System, Road Departure Mitigation, Blind Spot Info System, and Collision Mitigation System.

The contact owns a 2018 Honda Accord. While the contact's wife was driving at a moderate rate of speed, the Forward Collision Avoidance: Automatic Emergency Braking system engaged erroneously with the "Brake" warning light illuminated. The failure recurred soon after the initial failure and the contact's wife was able to drive the vehicle to the residence.

On this day at approximately 1:20 p.m. the weather was clear and dry and there was very light traffic with no cars nearby and no debris in the roadway. I was driving approximately 45 MPH when my vehicle suddenly flashed and beeped the warning to brake and I felt the car brake hard as it swerved to the left entirely on it's own.

As I was driving down the street, the Automatic Emergency Braking system was activated and brought my vehicle to a complete stop! There was no vehicle directly in front of me and it almost caused the vehicle behind me to slam into me had they not veered into the other lane of traffice to avoid rear-ending me.

Over the past two weeks, I have encountered problems with my car's many lights. These issues have been related to issues with the braking system, collisions, road departure, emission system, ACC system, vehicle stability, and electric power system. By disconnecting the battery, the lights have been switched off.

2018 Accord consistently has the warning pop up for the the crash mitigation system and tells me to visit the dealer. Cruise control just stop working while driving. When I turn the car off and back on it resets, and then 10-20 miles goes by and the error pops up again.

On [XXX], while I was driving from St. Petersburg, FL to Tampa, FL, I experienced phantom breaking on the highway. The vehicle gave brake warning and started breaking automatically.

My Honda Accord 2018 with 49,000+ Mileage suddenly showed multiple warning lights on the dashboard causing Parking Break to malfunction; ACC, Collision Assist malfunctions and many other warning lights appeared. I brought it to Honda Waldorf Maryland and they told me it was definitely the 2 Rear Calipers as they diagnosed, but this DID NOT solve the problem after replacements.

For the last couple of weeks, a bunch of warnings pop up related addaptive cruise control, collision mitigation braking and so on. The car ACC would stop working and car would auto brake without hitting brakes. I have checked online and see NHTSA has identified this issue but no action was taken.

While I am driving down the highway, my brakes randomly engage and I get an error message that says collision, mitigation breaking system error please see dealer.

Automobile automatically, abruptly and forcefully applied the brake during normal driving. No apparent obstacle appeared that should have caused this behavior. However, the time this occurred was late in the day and long shadows of trees and shrubs were crossing the road at the time.

My acc went out along with my collision mitigation system and no accident just for no reason.

I was driving my vehicle on an open highway. There were no road hazards or other vehicles in front of me when my car slammed on the brakes. The brakes caution light flashed and beeped on my dashboard and the car slammed on the brakes.

Acc, breaking system, lane departure, collision warnings all on. Cruise control not working! The cmbs is not functioning properly.

The contact owns a 2018 Honda Accord. The contact stated that while driving approximately 40 MPH, the Forward Collision Avoidance braking system erroneously activated causing the vehicle to abruptly stop in the middle of the road. During the failure, there were no other vehicles or objects nearby.

I was driving on a road with no other cars around at about 40 miles an hour and the collision mitigation system flashed the brake signal a few times and tried to stop very suddenly. I pushed on the gas to fight it and it released the brake.

The CMBS (Collision Mitigation Braking System) had another failure. This is due to the Radar Sensor being blocked and then other safety systems in the vehicle having cascading failures. In the winter of 2019, the Radar Sensor had failed catastrophically and I had to take the vehicle in to the dealer where they, supposedly, performed some sort of an adjustment.

The CMBS (Collision Mitigation Braking System) had another failure. In this case, there was "phantom braking", whereby the car abruptly applied breaks without an abstruction in fron of the vehicle. I have filed several complaints with NHTSA and, yes, "have taken the vehicle to the dealer" more than once for issues with the CMBS, to no avail.

I was using the cruise control feature while driving and it gave multiple errors. It happens each time I use the cruise control feature and assisted driving feature. The errors it gives are: 1.

While I was driving down Highway 101 near Mountain View near the Shoreline off-ramp, the vehicle's CBMS activated at highway speed even though there was no car in front of me. The weather was cloudy but visibility was good. The vehicle displayed "BRAKE" together with a warning sound, and the car suddenly decelerated.

While driving in stop and go traffic on the highway with the adaptive cruse control system enabled the system will suddenly stop working. A message appears on the dashboard information panel "Braking Mitigation System Error/Failure: Bring to Dealer". This has occurred twice in 2022, and once or twice in 2021.

While I was driving at 45mph and there was no vehicle/object in the object, Automatic Emergency Braking was applied and released. Luckily there wasn't any vehicle right behind otherwise I could have been rear ended. This whole experience was quite shocking and it took me a while to recover from it.

Extended highway driving(500+miles). Collision Mitigation Problem continues to show as alert in dash. Does seem to reset when vehicle turned off and back on but this is not a new problem and a major reason for purchase

The contact owns a 2018 Honda Accord. The contact stated that while driving 35 MPH, the Forward Collision Avoidance sensor activated independently, causing the vehicle to stall. The contact stated that the brake warning light was illuminated.

My vehicle has activated the collision avoidance/emergency braking on numerous occasions for no reason. I have taken it to my local Honda dealer for this problem, and since they cannot recreate it, they claim there is no problem. It generally happens when there are lines in the road, or a change in the color or the road surface.

Driving at 70 MPH on interstate 74 in cruise control the vehicle automatically braked on its own nearly causing a rear end collision by the semi following. Vehicle then proceeded to de-rate down to 40 MPH and would not accelerate beyond this causing us to drive down the highway with our hazards on over an hour home.

I had taken my vehicle in to dealership on multiple occasions for the vehicle stating “road departure mitigation system problem” multiple times and every time I was told there wasn’t an issue. Eventually the system completely stopped working and the dealership wanted to charge me over $3,000 because I was about 5,000 miles over warranty. I never fixed it.

I got a Collision Mitigation Braking System warning while driving at a high speed > 60 MPH on the Interstate with adaptive cruise control turned on. The system suddenly cuts off speed and lost cruise control. I have to stop on road side, turn off the car and restart it for the warning go away.

The car’s Collision Mitigation system stops working for no reason, causing me to completely lose my cruise control until I can turn off the car and restart it. This has happened in stop-and-go traffic on the Interstate while the car is under the control of the adaptive cruise control as well as while driving down the road with absolutely no other cars around me.

Collision Mitigation braking system has engaged several times while driving in the city and Highway when there are no obstructions. Speeds vary from 35mph to 60mph.

Quite simply we were driving through a construction zone that was down to one lane with monitored traffic. My wife was driving and approaching a steel plate in the road that was laid on top of existing asphalt. While slowing down to move over the plate at a slower rate of speed the automatic breaking brought the car to an unnecessary stop almost causing a collision from behind.

The vehicle on two separate occasions has out of the blue completely engaged in an automatic emergency braking when there is no reason to and no other vehicles on the road. Most Recently I went to merge on the highway, there was no traffic infront of me and it was sunny and daytime. The vehicle engaged the emergency braking very aggressively and my car went from 65-35 quickly.

Going about 10mph down a side street when emergency brake automatically caused my car to stop but nothing was in front of me. Car came to a complete abrupt stop which jolted me forward, but then resumed driving like normal. Yes available for inspection as it has not been taken in or inspected for this problem, it only happened once.

Two times while driving on the highway at 75-80 MPH with CMBS system on and utilizing ACC. Out of nowhere, vehicle drops speed, ACC OFF notice comes on and an alert stating Collision Mitigation Braking System Problem. See dealer pops up.

I had owned a 2018 Honda Accord which I had purchased in 2019. I had owned the car for about 6 months when the situation occurred. I had been about 30-50 before a railroad track and had already slowed down to 30-35 MPH at this point.

When driving on the freeway (>50mph) with no obstacles visible in front of me, the Forward Collision System will occasionally cause the HUD to rapidly flash and warn me to “BRAKE”. It will display this message for a couple of seconds before disappearing. I have noticed that this has a higher chance of occurring when I am driving towards the sun.

Three times now I have been driving with no obstructions in front of me and the Automatic Emergency Braking System has flashed "BRAKE" on the dash and then slammed the brakes on. One of the times, I was on the freeway going approximately 60 MPH. Everything on the seat next to me went flying and my seatbelt locked, hurting me (I did not see a doctor as it was not necessary).

While driving 35mph and accelerating, emergency braking system deployed. The lights on the dash and audible beeps presented simultaneously. There were no other cars on the road other than a parked vehicle off to the drivers side.

Routine and ongoing false and nuisance braking warnings from collision mitigation system. Triggering of the warning is presumably a precursor to erroneous activation of automatic braking.

Certain roads on my commute have hills where automatic braking has engaged and almost caused accidents over past year. Also, vehicles crossing in front of me or changing lanes when I have full view, car has braked hard. These incidents have happened at least 8 times in past year.

Driving no other car in front of me and my car brake and Pulled to the side. Very scary with my children in the car. My car has sounded as if there was going to brake before without anything if front of me but this time it jerked and pulled to the side.

The contact owns a 2018 Honda Accord. The contact stated that while driving at various speeds, the Forward Collision Avoidance feature engaged without incident with the brakes warning light flashing on the instrument panel. The contact had taken the vehicle to a dealer however, the mechanic was unable to duplicate the failure.

I am getting warnings of brake system problems including electric parking brake problem says it’s not available, brake hold system problem,brake performance reduced. Adaptive cruise control system problem, collision mitigation problem, and road departure mitigation problem.

I was going down the highway and my vehicle came to an abrupt stop. It was in the middle of traffic. I was in NO danger prior to this happening.

I have had multiple instances (since purchasing the vehicle new at the end of the of the 2018 model year (Sept 2018) of my 2018 Honda Accord LX suddenly braking when there was no reason to brake. I talked with my service advisor at Dave Mungenast Honda in St.

In the past 2 weeks, my Honda Accord has suddenly started braking without reason. Once this was on the interstate, the other time it was on an exit ramp from a state highway. I did notice that on the exit ramp, the front of the vehicle was looking into the sun.

The contact owns a 2018 Honda Accord. The contact stated while driving 50 MPH, the Collision Mitigation Braking System engaged abruptly while there were no objects or other vehicles nearby. There were no warning lights illuminated.

Automatic braking was activated on several occasions when there was no car or object in sight. This happened twice on the interstate at 70 MPH speeds and once along a 40 MPH road. Thankfully nobody was close behind or I would have been rear ended and hurt.

Car periodically brakes on its own, sometimes when no other cars are around vehicle. It is available for inspection upon request. In the 3 years I've owned the car, it has done it numerous times, once on the expressway.

For the past three years, I have leased a 2018 Honda accord which I got for my wife and my child due to the "safety features " Of the vehicle. But all of a sudden throughout the years it has been breaking out of nowhere while driving on the highway with no objects obstructing front or sides.

I read about Investigation PE22-003 and wanted to add to that investigation. There’s a small hill near my house where the automatic braking system almost always tells me I’m about to crash. The brakes are never applied because I figure I crest the hill before I get close enough that it brakes for me.

The contact owns a 2018 Honda Accord. The contact stated that while driving approximately 40 MPH, the braking system erroneously activated causing the vehicle to abruptly stop. The contact indicated that during the failure no vehicles or objects were nearby to cause the collision avoidance system to activate.

I just learned of the investigation the NHTSA is doing regarding the sudden braking issue on Honda Accords. My 2018 Honda Accord Sport has done this maybe 15-20 times, in most cases with no visual or audible alert before braking. There have however been a few instances when the vehicle DOES sound a visual and audible alert for no reason, but doesn't brake.

The system regularly malfunctions and it has almost caused 2 accidents. You expect the car to stop but it fails. The brakes also have issues and now my car starts without even pressing my foot on the brake first.

The CMBS will slam on the brakes in wide open road condition. It happened at least 5 times. I have since made a habit to turn off the CMBS before I drive (going on 2 years turning it off).

While using Adaptive Cruise Control the Collision Mitigation Braking System turns off with no rhyme or reason. This happens often ... 5 to 10 times per month depending upon how many miles I use the car that month.

Collision mitigation braking system problem appeared with no reasoning.

I was driving home in the rain on the interstate when my car suddenly braked on its own. Luckily, no one was immediately around me at the time because the sudden braking resulted in my car sliding into the lane to the right of me, towards the cars in the next lane over. It spun to where I was facing the oncoming traffic and sliding toward the dividing wall with the passenger side to the wall.

The contact owns a 2018 Honda Accord. The contact stated while driving at various speeds, the Forward Collision-Avoidance Automatic Emergency Braking activated inadvertently and without warning. The contact had taken the vehicle to a Honda dealer where they informed her that her gear shifter may have caused an electrical short.

The contact owns a 2018 honda accord. The contact was driving at 55-65 MPH, when the collision mitigation braking system warning light illuminated on the instrument panel. The vehicle loss cruise control, emergency braking system and the side blind spot alerts failed.

I2 weeks ago I had my car's computer system updated as per the recall notice. Everything was fine then 2 days ago I noticed on the heads up display "cruise) which had never been there before. I set the speed at 65 on the freeway and it held the speed fine, however, as I approached another vehicle from behind it did not slow down to match the speed of the other car.

While driving in the highway at night, the vehicle warns potential collision and tries to brake automatically. When I step on the brake and push a little, the warning goes away. This is especially dangerous because at 50 or 60 MPH the car warns and tries to brake hard.

The cmbs (collision mitigation braking system) had another failure. This is due to the radar sensor being blocked and then other safety systems in the vehicle having cascading failures. Last winter, the radar sensor had failed catastrophically and I had to take the vehicle in to the dealer where they, supposedly, performed some sort of an adjustment.

Tl* the contact owns a 2018 honda accord. While driving approximately 60 MPH, the collision mitigation system warning indicator illuminated and activated when there were no vehicles in close proximity. The contact stated that the vehicle braked abruptly and the vehicle decelerated to 30 MPH.

Your car's forward collision avoidance system applied the brakes on its own while you were driving at 35-40 MPH, even though there was no obstacle ahead and no warning light appeared. This phantom braking happened around 100,000 miles on your vehicle. The issue may require inspection and recalibration of the forward collision warning sensors and camera system.

The contact owns a 2018 Honda Accord. The contact stated while driving 65 MPH, the vehicle independently made a sudden stop. The brake warning light illuminated along with other unknown warning lights.

While driving, on three accounts my honds accord independently applied brakes while my foot was on gas petal. The car slowed jerked and stopped. It regained speed after I pulled off the road.

I Honda Accord recently has been displaying up to 17 error messages out of the blue. It doesn’t matter if I’m going 30 MPH or 80 MPH. It happens randomly and there is a power loss associated with it.

I was driving on interstate behind line of trucks in construction zone at 55mph. It was raining lightly. When zone ended, I pulled into left lane and accelerated to 70 MPH.

The warning lights for many areas has come on without warning. The car runs and drives fine. Took it to Honda.

Vehicle will sometimes automatically emergency brake with nothing in front of it

Vehicle emergency braking system randomly triggered, causing me to completely stop from 40mph to 0mph in the middle of a intersection. Almost got rear-ended. NO vehicles were infront of me to trigger the emergency braking system.

Getting a dash warning that all mitigation systems are not working and to see my dealership

To the highway safety I would like to inform that I purchased a 2018 honda accord and it has been nothing but a nightmare and safety issue for me and my family.

Braking system engaged while driving, slamming on brakes for no reason within first 6 months of having purchased my 2018 Honda Accord EX. While driving the car on a normal highway with no cars in front of me, the car suddenly brakes and then the brake releases. The car came to a complete stop for no reason while driving around 55-60mph on the highway with no cars in front of me or to the sides.

My car will suddenly brake hard on its own with nothing in front of it at random times. The dash may or may not say BRAKE when this happens. This did not start until I had my windshield replaced.

Driving on expressway going around ramp car started braking at speed of 65mph with no cars in front of me only cars behind cars behind had to hard brake to keep from hitting me .

Warning lights comes on and the car slows down

I have 2018 Honda accord sport 2.0 manual transmission. I’m dealing with the ABS module malfunction where the ABS module board is detective due to the pins being unsoldered due to intense heat in the engine area. To repair the ABS module it costs around $1200.

My Honda Accord 2018 with 49,000+ Mileage suddenly showed multiple warning lights on the dashboard. Honda Waldorf Maryland misdiagnosed that it was definitely the 2 Rear Calipers, but this DID NOT solve the problem after replacements.

A car merged into my lane, the car braking light went on and a beeping noise sounded. After the car in front of us turned and nothing was in front of us, our Honda Broke abruptly and if it wasn’t for the seatbelt I think I would’ve hit the windshield. My daughter is afraid to get In the car because of this incident.

Random braking. Freeways or side streets. Fast or slow.

I was traveling on interstate 65 in alabama running about 70 MPH when suddenly the brakes slammed on automatically. The car behind me had to swerve over in the next lane to keep from hitting me from behind. this is the 3rd time this has happened but this last time almost caused a wreck.

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle experienced phantom braking. The vehicle was taken to the dealer; however, the dealer was unable to duplicate the failure.

The contact owns a 2018 Honda Accord. The contact stated while driving 60 MPH with the cruise control activated, the vehicle abruptly stopped with unknown warning lights illuminated. The vehicle was not diagnosed or repaired.

I have had a few instances where I was driving and the brake warning light started flashing and the car broke. This latest incident was today and it was extremely dangerous and scary.

ALL dashboard warning lights come on.(brakes, VSC, steering, etc) Message says take to dealer. After doing a Google search, it appears to be a COMMON ISSUE for Honda Accords for 2018 and newer. They will come on and either stay on for days/weeks at a time and then just go off on their own.

Well I've had the car for about a year now and it has been good for the first few months, then I ran into a snag. All the orange warning lights for my safety features popped up and the vehicle was applying the brakes on its own. So I took it to the dealership and they told me it was a taillight, so I spent 500 bucks on one.

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer.

The vehicle gave me a warning for the emergency breaking and began to aggressively brake for no reason. This has happened to me three separate times. Case 1: There were no cars in front of me, a few cars behind but not too close.

Two times, pulling into my driveway at a slow speed, the car automatically stopped suddenly. There were no shadows to provoke this. I have not seen a dealer about this because I did not want to incur any fees.

I own a 2018 honda accord sport on 7 different time's in the last four years my car has made sudden stop all by itself I have talk to the dealer about it but when they check it out they say everthing is fine and they don't know why it did it. It's happened 3 time on the freeway and the other four times in arround town driving. speed ranged from 15 miles an hour up to 70.

I want to report that I experienced the random emergency braking that you are currently investigating. It only happened once, about a month ago: I was driving along a paved country road on a straightaway (~40mph). Daytime/clear, dry paved roads.

I was driving and there were no objects or obstructions near my car when all of a sudden the car randomly breaks on its own for no reason. It startled me and jolted me forward. Luckily I was only going about 40mph at the time and nobody was behind me.

The contact's wife owns a 2018 Honda Accord. The contact stated that while driving at various highway speeds, the vehicle would independently downshift as an orange "brake" warning light would illuminate on the instrument panel. They had taken the vehicle to a dealer where they found no fault with the vehicle.

The contact owns a 2018 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle experienced unintended braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer.

My vehicle randomly applies the brakes during normal driving with no obstacle in its way. This happens intermittently but poses danger as there will be no car in front of me so applying the brakes and halting my car could cause the car behind me to drive into my vehicle.

The adaptive cruise and emergency braking systems. Driving on the highway the car suddenly brakes as if a car is right in front of you. There is no car in front.

From time to time my AEB will flash on my dash. A lot of my driving is highway so I can be driving anywhere between 40-65 MPH given the road I'm on. On two separate occasions my car has flashed and braked abruptly while I was doing about 50 MPH.

I will just be driving down the highway and sometimes the orange BRAKE light will light up and sometimes it will light up and just start slowing down. Several times I will be the only car moving thru an intersection with a green light and it will light up BRAKE and hit the brake.

Vehicle occasionally displays large orange "BRAKE" warning on dash when there are no vehicles or obstructions ahead. It then applies the brakes. This happens both when Adaptive Cruise Control is engaged, and when it is not.

Three or four times in the 4 years since we purchased our 2018 Accord Touring it has unexpectedly applied its brakes and illuminated the AEB (orange) warning light on the instrument cluster. This has happened when the car was being driven in heavy traffic at highway speeds and (the latest occurrence) when the car was stationary but traffic on each side was accelerating.

Supplemental Restraint System failure will pop up at random times maybe every other drive, then that code goes away. Just recently the ACC and Brake System flashes "Problem see dealer" as well as the head unit/display turning off and then back on intermittently. Front interior lights will turn on then turn off, sometimes immediately, and this has all been in the last year they've compiled.

I was driving out of nowhere all the lights came out toke it to the dealer they fixed 2 week later I turn on my car and the same problem came out

The contact owns a 2018 Honda Accord. The contact stated that while driving at various speeds with the cruise control engaged, the vehicle would independently brake as a brake warning light would illuminate on the instrument panel.

Tl* the contact owns a 2018 honda accord. While driving approximately 45 MPH, the automatic brake system engaged independently. The failure occurred twice.

Tl* the contact owns a 2018 honda accord. While driving various speeds, the road terrain changed and the brake assist engaged, which caused the vehicle to stop abruptly. In addition, the lane assist feature was pulling the vehicle.

On August 7, 2025, the automatic braking system alerted with the sign break and then proceeded to stop the car when there was no object or vehicle in front of me. This would have been extremely dangerous. If there was someone behind me this is not the first time this has occurred it has happened several times.

I was behind another vehicle with the adaptive cruise control on and been following the for some distance at a speed below the cruise control setting. Warning came on for the braking mitigation, cruise control disengaged, vehicle began coasting but did not brake. I continued home driving without any other changes, but warning stayed on.

Car goes in limp mode once the brake system lights come on. When the brake light system comes on, none of the functions for the automatic breaks or electrical portion of my vehicle works. The car will act as if it will not accelerate right before the codes start to appear on the car.

Failure in road monitoring camera prematurely, 70,000 ish miles

I was traveling down the road and I passed a bus that was in the right lane. I think when I reached the bus shadow that’s when the automatic brake warning came on and then my car went from 50 to 15mph instantly tossing everything in my car and hurting me neck.

Unintended activation of CMBS braking and warning system causing rapid vehicle deceleration. Deactivation of active cruise control due to CMBS errors.

While driving with nothing surrounding me my car applied a hard brake out of nowhere.

As I was driving in a 25 MPH zone (thank goodness) and I drove over the metal construction paver on the road my car brake alert started beeping then made my car come to an abrupt stop! Thank goodness I wasn’t going that fast and no one behind me was close enough to hit me! This sensor needs to be corrected!

My car will randomly brake. This has happened multiple times while driving on the interstate. I will be driving 76 MPH and the emergency braking system will brake when there is nothing in front of me.

2018 Honda Accord Twice last week my car suddenly braked with no obstruction in front of the vehicle. I was on a straight section of the roadway. Thankfully no one was directly behiind me.

I was stopped at a light and was the first vehicle. When it turned green I started to go. I saw a short ways in front of me one of those metal plates over a hole in the road.

Occasional braking when there is no reason for the car to brake

I saw an article that this was being investigated, and I’ve experienced the same issue multiple times. I will be driving on the highway with no car directly in front of me and every so often my car automatically emergency brakes as if there is a vehicle in front of me that I’m about to hit. This happened to me again just the other day.

Automatic emergency braking occurred three different times for no apparent reason. The car slowed down on a major road. I never reported it.

I was traveling on [XXX] transitioning to connect the [XXX] . The emergency brake abruptly engaged and jerked/slammed my upper body forward and then backward. There was no vehicle in my path that warranted the auto braking system engagement.

My 2018 Honda Accord has not been able to drive properly the emergency brake signs has come on repeatedly stating it will not work , the car has decreased speed and ever since the recall notification came on Wednesday 12/20/2023 it does not drive anymore. I do have adequate fluids, gas etc however it will not drive. I called Honda Parkville in Maryland and was told there's nothing they can do.

When going under an overpass, my cars automatic braking system senses the shadow from the bridge as something in font of me and my car slams on brakes. No incidents have occurred at this time. It has happened at least 10 times and each time no one has been behind me.

Car randomly brakes while driving

3 Incidents of auto braking without a car being in front of me. My vehicle abruptly applied the brakes from underneath my foot so hard, that myself and passengers jerked forward. This almost caused the vehicle behind me to run into me.

On about 7-10 occasions since purchasing car new, the automatic braking system will engage brakes for no reason. These have all been in cuise control mode and with no cars in front of me. It is a very hard braking and a many of the times on interstates going 70 MPH.

On April 7 at 1230p I was driving about 45 MPH on Lindbergh Blvd in Creve Coeur. As I was moving into a construction area there was a sign to lower speed to 35. I lowered my speed with my brakes and at the same time traveled over a metal plate on the road.

All of my safety features in my car when it comes to driving down the road have completely failed. Adaptive cruise control lane assist brake system errors. The car just stops in the middle of the road.

While driving at highway speeds the automatic emergency braking will trigger. First the flashing of the dash and then the audible beeping and then the car brakes very hard and then releases without anyone ahead of me.

Automatic braking has randomly come on, causing harm or injury to those traveling in the vehicle. The few times that is has engaged has never been due to a close vehicle or object in front of the car.

driving and without any vehicles nearby the brake lights came on and car brakes activated to a hard stop.

On July 31st, 2022 at approximately 1135AM Central Time on I-90 westbound near Dekorra, WI when passing a tow truck in the middle lane as I was in the right most lane the Automatic Emergency Brake system sounded visual and audio alerts urging me to a *Brake Now*. Adaptive Cruise Control was engaged at approximately 73mph.

Ghost braking for no reason I could be going 70 MPH and it'll slam on the breaks with nobody in front of me or anything

I was driving my car and was at the time passing through an intersection and I had no car in front or back of me and out of nowhere my car showed an alert to "BRAKE" and the car slammed on the brakes for me and brought the car to an almost complete stop. This appears to be the phenomenon called Phantom braking and it was terrifying if someone had been behind me.

Breaks came on for no apparent reason and put vehicle into a side ways skid. Lane Landed up in meridian .

Unexpected CMBS activation. There were no cars in front of me.

When I'm driving the braking warning flashes out of the blue and there is no one in front of me. Then it goes away. Also randomly my infotainment system just turns off and on out of the blue as well.

The car is braking by itself because of honda sensing. There are no cars near me but it normally thinks there is seems to not work on sunny days

When vehicle is on, safety features like lane keep assist, adaptive cruise control, blind spot indicators, traction control, door locking, hands free phone call answering and hanging up buttons on steering wheel are all not working. My information sceen is locked and cannot be changed.
