2005 Toyota Sienna Brakes Problems

While driving at 65 mph on a dry road with a slight curve, your ABS braking system unexpectedly engaged on its own, causing the van to lose power and fishtail dangerously. Although no collision occurred, this happened without warning and could have caused a crash if other vehicles were nearby. A diagnostic code reader showed no stored error codes, making it difficult to identify the root cause. The issue may require a thorough inspection of the ABS system components and sensors to determine why the system activated when it shouldn't have.

ABS PUMP STOPPED WORKING. NO WARNING. BRAKES FAILED,RAN INTO MY GARAGE. TOOK TO LOCAL MECHANIC. HAD TO PUMP BREAKS TO GET IT THERE OR PAY TOWING COST. LEARNED OVER 2000.00 FOR THE PART. IT IS KNOW TO GO OUT HE SAID AND SHOUOD GAVE BEEN A RECALLED ITEM...

ABS BRAKE PUMP MODULE. WENT OUT CAUSING ACCIDENT. NO WARNING. ABS LIGHTS CAME ON. TOOK TO SHOP. DRAINING BATTERY,CAUSING BRAKES TO FAIL. SHOUOD BE RECALLED DUE TO NO WARNING,COMPLETE BRAKE FAILURE,CAUSING VEHICLE TO BE DANGEROUS, NOT ROAD WORTHY.

PARKING BREAK DOES NOT ENGAGE UNTIL AFTER SEVERAL TRIES OF ENGAGEMENT. AND MANY TIMES DOES NOT ENGAGE AT ALL. GRADE LOCATION OF THE VEHICLE DOES NOT MATTER (E.G. HORIZONTAL TO >% DEG). ATTEMPTS ARE ONLY MADE WHILE VEHICLE IS IN PARK. (IT IS NOT ATTEMPTED WHILE VEHICLE IS IN DRIVE, REVERSE OR NEUTRAL)

SINCE 7/2019 TO NOW, 10/2019, I'VE HAD INTERMITTENT HARD BRAKE PEDAL. LETTING UP ON THE GAS PEDAL, THE VAN BEGINS TO STOP RIGHT AWAY. THERE'S NO RHYME OR REASON FOR THE HARD BRAKE PEDAL, ITS AFFECTING THE FRONT RIGHT WHEEL, AND IT SMELLS BAD. THERE'S A VIBRATION AT TIMES, AND WOBBLE. AFTER THE VAN SITS FOR AN HOUR, THE BRAKES ARE FINE UNTIL NEXT TIME. TODAY, BACKING OUT OF A PARKING SPOT, IT WAS DIFFICULT TO PUT THE VAN IN REVERSE, AND LETTING OFF THE BRAKE, THE VAN WOULDN'T ROLL BACK. I HAD TO GIVE IT QUITE A BIT OF GAS TO GET IT TO MOVE. THE VAN DIDN'T WANT TO GO MORE THAN 10MPH IN A 35MPH ZONE. ALL OF THIS HAS HAPPENED SINCE A NEW BRAKE BOOSTER WAS INSTALLED. THERE IS A NEW CALIPER ON THAT RIGHT SIDE, AND BOTH FRONT BRAKES GOT NEW BRAKE LINES. THE PADS STILL HAVE A LOT OF MEAT ON THEM. I CAN DRIVE THE VAN JUST FINE, THEN SOMETIMES GET BACK IN THE VAN LATER, 1 TO 6 HOURS LATER, AND THE BRAKE PEDAL IS HARD. IT OCCURS WHEN THE VAN HAS BEEN SITTING ALL NIGHT AND HALF THE NEXT DAY, OR IT CAN HAPPEN WHEN I'M DRIVING IT. THERE IS SOMETHING WRONG WITH THE BRAKES ON MY 2005 SIENNA. NOBODY CAN FIGURE IT OUT.

WHILE DRIVING AT 55 MPH HIGHWAY SPEED AND CURVING GENTLY TO THE RIGHT, THE VSC SYSTEM ON THIS MINIVAN EVIDENTLY PICKED UP A FALSE INDICATION OF A SLIP IN THE VEHICLE'S TRACTION. THIS CAUSED THE CAR TO AUTOMATICALLY APPLY THE BRAKES ON THE LEFT SIDE, PULLING THE VAN'S DIRECTION FROM RIGHT TO LEFT, AND SLOW THE CAR QUICKLY FROM 55 TO 35 MPH, WITH VEHICLES BEHIND ME QUICKLY CLOSING IN ON THE REAR END. WITHIN SECONDS THE AUTOMATIC BRAKING CEASED AND I WAS ABLE TO REACCELERATE BACK TO NORMAL HIGHWAY DRIVING SPEED. THE ENGINE WAS NOT STALLED IN THE PROCESS.

ABS LIGHTS ACTIVATE GOING AT SPEEDS FROM 15-60 ON ANY TYPE OF CURVES THEN STARTS BRAKING AUTOMATICALLY. THIS SITUATION HAS BEEN GOING ON FOR A WHILE AND AS LATE AS THIS PAST WEEKEND (10 TIMES) ON HIGHWAY 299 WEST FROM REDDING,CA. - EUREKA, CA. THESE SENSORS NEED TO BE RECALLED.

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT STATED THAT WHEN THE VEHICLE WAS SHIFTED INTO REVERSE, THE BRAKE PEDAL WAS DEPRESSED BUT FAILED WITHOUT WARNING. THE VEHICLE ROLLED INTO THESTREET. THE CONTACT HAD TO CONTINUOUSLY PUMP THE BRAKE PEDAL IN ORDER TO STOP THE VEHICLE. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 105,000.

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. WHILE DRIVING VARIOUS SPEEDS, THE ABS SEIZED INTERMITTENTLY AND THE ABS WARNING INDICATOR ILLUMINATED ONCE DURING THE FOURTEEN TIMES THE ABS FAILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE BRAKE ACTUATOR FAILED AND WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 135,000.

2005 SIENNA ANTI SKID ACTIVATES WITHOUT PROVOCATION, SIMILAR TO MANY OTHER COMPLAINTS, SKID VSC COMES ON FOR NO REASON, PUTTING ON BRAKES UNCONTROLLABLY. HAPPENED ON FREEWAY IN RAIN AND ALMOST LOST CONTROL. SEE THE WEBSITES AND DEALER COMPLAINTS. SOMEONE IS GOING TO GET KILLED HERE. DO SOMETHING! INTERMITTENT AND VERY DANGEROUS CAN CAUSE OUT OF CONTROL SKIDDING AND HAPPENS WITHOUT WARNING IN WET OR DRY CONDITIONS

IT JUST TURN ON ANTI-LOCK BRAKE SYSTEM AND BRAKE LIGHTS. TOYOTA TOLD ME THAT THE ACTUATOR IS DAMAGED, REPLACEMENT COST $ 1,900.00. SAFETY ISSUE

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. DURING COLD WEATHER, THE REAR BRAKES FAILED TO ENGAGE. THE CONTACT HAD THE REAR BRAKES REPLACED, BUT THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 88,000.

APPROACHING FULL STOP REALIZED THAT ALTHOUGH BRAKING CAR WAS NOT SLOWING. BRAKE AGAIN AND AGAIN THEN CAR FELT AS IF COASTING IN FREE FALL THEN SHOT FORWARD LIKE AN AIR PLANE TAKING OFF. KEPT SLAMMING ON BRAKE; SUDDENLY CAR STOPPED MOVING FORWARD - NO HUGE JERK/LURCH AS ONE MIGHT EXPECT FROM SUDDEN STOP JUST......STOPPED. CONTINUED TO DRIVE HOME. A FEW TIMES I PRESSED ACCELERATOR AND THEN BRAKE TO COMPARE TO "EVENT" AND AM CONVINCED I WAS BRAKING THE ENTIRE TIME OF THE "EVENT". I AM TRAINED MOVEMENT SPECIALIST AND KNOW MY FOOT WAS ON BRAKE NOT ACCELERATOR. TOWED CAR TO DEALER TODAY. TOYOTA CAN'T FIND ANYTHING WRONG WITH CAR AND SUGGESTED I HAD BEEN STEPPING ON ACCELERATOR. *TR

2005 TOYOTA SIENNA. CONSUMER WRITES IN REGARDS TO BRAKE FAILURE. *SMD THE CONSUMER STATED SEVERAL WEEKS AGO, HE WAS TURNING AROUND IN THE DRIVEWAY, AND WHEN HE PRESSED DOWN WITH HIS RIGHT FOOT, THE ENGINE ROARED AND THE VEHICLE JUMPED FORWARD UNTIL HE APPLIED MORE PRESSURE TO THE BRAKE PEDAL, AT WHICH POINT THE VEHICLE STOPPED. THE CONSUMER REALIZED THE BRAKE PEDAL COULD BE DEPRESSED EASILY BELOW THE LEVEL OF THE GAS PEDAL, HENCE THE ROAR AND SURGE. THE CONSUMER WAS INFORMED BRAKE PEDALS WERE NO LONGER ADJUSTABLE AND WHEN THE MECHANIC CHECKED THE VEHICLE, THE BRAKE MASTER CYLINDER WAS FAILING AND ACCOUNTED FOR THE BRAKES NOT FUNCTIONING PROPERLY AT TIMES.

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 30 MPH, THE TRACTION CONTROL WARNING INDICATOR ILLUMINATED WITH A CHIME. THE VEHICLE BEGAN TO BRAKE INDEPENDENTLY AND THEN VEERED OFF THE ROADWAY. THE FAILURE RECURRED FIVE TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

I WAS DRIVING IN TRAFFIC AND BRIEFLY LOOKED TO SIDE OF ROAD. THEN LOOKED BACK AND NOTICED TRAFFIC STOPPED AHEAD OF ME. FULLY APPLIED BRAKES (HARD) BUT NO BRAKING, SQUEALING OR ABS. FULL AIRBAGS BUT FORTUNATELY NO INJURIES. LOOKING AT THE SCENE I SHOULD HAVE HAD PLENTY OF DISTANCE TO STOP. CAR TOTALED. *TR

2005 TOYOTA SIENNA BRAKE FAILURES. THIS SEEMS TO BE AN INTERMITTENT PROBLEM - STEP ON BRAKE PEDAL - CAR DOES NOT STOP. BRAKES HAVE BEEN CHANGED AND REINSPECTED. A SEARCH ON THE WEB SHOWS THAT THIS IS A KNOWN PROBLEM AND MANY COMPLAINTS HAVE BEEN FILED REGARDING THIS ISSUE. *TR

MY WIFE WAS DRIVING OUR 2005 TOYOTA SIENNA VAN TO PICK UP OUR SON FROM SCHOOL. AS SHE WAS PULLING INTO A PARKING SPACE, SHE PUSHED ON THE BRAKES TO SLOW DOWN FURTHER. HOWEVER, THE VAN DID NOT SLOW DOWN, BUT INSTEAD ACCELERATED, CAUSING THE VAN TO HIT A TREE AT THE END OF THE PARKING SPACE AND THE CAR ON THE OTHER SIDE OF THE TREE. SHE CONFIRMED THAT SHE ONLY HIT THE BRAKES, AND NOT THE ACCELERATOR. AFTER READING MULTIPLE ONLINE REPORTS OF OTHERS PUSHING ON THE BRAKES AND THE TOYOTA SIENNA VANS ACCELERATING, I DECIDED TO FILE THIS REPORT. *TR

I HAVE AN INTERMITTENT FAILURE WITH THE ANTI-SKID. ONCE OR TWICE A MONTH I WILL BE TURNING WITHOUT ANY BRAKES ON AND THE ANTI-SKID LIGHT COMES ON AND THE CAR BEHAVES LIKE IT IS TRYING TO COMPENSATE FOR A SKID. *TR

VEHICLE WAS A 2005 TOYOTA SIENNA VAN. VEHICLE HAS ALWAYS BEEN SERVICED BY TOYOTA DEALERS.ON 8/29/09, I HAD REAR BRAKES REPLACED BY LOCAL TOYOTA DEALER WITH 77,410 MILES ON THE VEHICLE. 10 DAYS LATER, ON 9/8/09, MY ROOMMATE WAS PICKING UP CHILDREN AT SCHOOL. DRIVING ON A 4 LANE ROAD IN TOWN GOING 35-40MPH. TWO H.S. STUDENTS ABRUPTLY STOPPED IN HER LANE. MY ROOMMATE STATED SHE APPLIED BRAKES BUT COULD TELL VEHICLE WAS NOT STOPPING OR SLOWING. RAN INTO REAR END OF A TOYOTA TACOMA P/U WHICH IN TURN REAR-ENDED A HONDA CRV. NO INJURIES IN ANY INVOLVED VEHICLE. HOWEVER, DUE TO THE EXTENT OF DAMAGE, MY SIENNA VAN WAS A TOTAL LOSS. AIRBAGS DID DEPLOY ON IMPACT. MY ROOMMATE STATED FROM THE BEGINNING THAT SHE HAD APPLIED THE BRAKE TO THE FLOOR AND THE VAN DID NOT BRAKE OR SLOW DOWN. THERE WERE NO BRAKING/SKID MARKS ON THE PAVEMENT AT AREA OF ACCIDENT. EITHER THE BRAKE SYSTEM TOTALLY FAILED OR THERE WAS FAULTY WORK DONE DURING BRAKE REPLACEMENT 10 DAYS EARLIER. *TR

BRAKE FAILURE IN A 2005 TOYOTA SIENNA. I SEE OTHER REPORTS OF THIS PROBLEM IN SIENNAS BASED ON AN ON-LINE GOOGLE SEARCH. THE PROBLEM, IN MY CASE, IS INTERMITTENT. BRAKE FAILURE HAS HAPPENED TWO TIMES WHEN ATTEMPTING TO STOP AT INTERSECTIONS. ONCE TO MY WIFE AND ONCE TO ME. THE PEDAL DOES NOT GO ALL THE WAY DOWN TO THE FLOOR, BUT PRESSING HARD ON THE PEDAL IS INEFFECTIVE TO STOP THE CAR IN A NORMAL DISTANCE. THE ABS SYSTEM DOES NOT ENGAGE DESPITE THE AMOUNT OF STRONG FORCE ON THE PEDAL THAT I EXERTED. THE CAR EVENTUALLY CAME TO A STOP, BUT IT FEELS AS THOUGH THERE IS NO VACUUM ASSIST. PUMPING THE BRAKE DID NOT HELP. THE PAVEMENT WAS NOT SLICK. THE BRAKES APPEAR TO WORK NORMALLY AT OTHER TIMES. *TR

I BOUGHT A NEW 2005 TOYOTA SIENNA VAN IN JANUARY 2005. MY COMPLAINT IS ABOUT THE BRAKES. EVERY 10,000 MILES THE BRAKES ARE COMPLETELY GRINDING METAL TO METAL AND THE ROTORS NEED TO BE REPLACED. WHEN I HAD JUST 12,000 ON MY CAR TOYOTA STATED THAT I NEEDED NEW BRAKES AND ROTORS. IT IS NOW 2010 AND I HAVE CHANGED THE ROTORS AT LEAST TWICE AND THE BRAKES STILL GO OUT APPROX. EVERY 10,000 MILES. THE TOYOTA REP HIMSELF TOLD ME THAT TOYOTA IS AWARE OF THE BRAKING PROBLEMS WITH THERE VANS AND THAT THE VAN IS TO HEAVY FOR THE SMALL BRAKING SYSTEM ON THESE VANS. THAT REVELATION CAME FROM THE TOYOTA SERVICE REP. I BELIEVE THERE IS BOTH A DANGER AND A DEFECT WITH THESE BRAKES ESPECIALLY IF THE VAN BRAKES CAN NOT SUPPORT THE WEIGHT OF THE VEHICLE AND 7 PASSENGERS. I BELIEVE THE FACTS TODAY SHOW THAT TOYOTA KNEW ABOUT IT'S BRAKE AND PEDAL PROBLEMS AND NEVER DID ANYTHING ABOUT IT. IF DOT RESEARCHED THE AMOUNT OF COMPLAINTS AGAINST TOYOTA VAN BRAKES YOU WOULD SEE A CLEAR PATTERN. SUBPOENA TOYOTA AND ASK FOR THESE CUSTOMER COMPLAINTS/INTERNAL MEMOS AND SEE HOW MANY THERE ARE. THANKS FOR YOUR ATTENTION TO THIS MATTER. I AM CONFIDENT THAT DOT WILL CONDUCT A COMPLETE INVESTIGATION REGARDING THIS MATTER. *TR

I WAS INVOLVED IN AN ACCIDENT WHICH SHOULD JUST BE A MINOR FENDER BENDER BUT LOST ALL BRAKES AND CAUSED MY 2005 TOYOTA SIENNA LIMITED AWD TO JUST KEEP ON GOING UNTIL I HIT A HOUSE AND THAT MADE MY VAN STOP. I WAS RUNNING 25MPH. MY SIENNA WAS TOTALED NOT BECAUSE OF THE INITIAL IMPACT BUT BECAUSE OF THE VAN HITTING THE HOUSE. *TR

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT STATED THAT WHEN SHE WAS DRIVING OVER ROUGH SURFACES, BUMPS OR POTHOLES AND TRYING TO DEPRESS THE BRAKE PEDAL, SHE NOTICED A GRINDING SOUND AND THE BRAKE WOULD NOT SEEM TO ENGAGE IMMEDIATELY. SHE STATED THAT THE CONDITION SEEMED TO EXIST ON EXTREMELY BUMPY ROADS. SHE TOOK THE VEHICLE TO THE DEALERSHIP 3-4 TIMES AND THE BRAKE PADS WERE REPLACED AND ROTORS WERE RESURFACED. HOWEVER, THE ISSUE WAS STILL PRESENT AFTER THE REPAIRS. SHE HAD NOT SPOKEN WITH THE MANUFACTURER TO-DATE. THE CURRENT MILEAGE WAS APPROXIMATELY 76,500. THE FAILURE MILEAGE WAS APPROXIMATELY 43,000.

BRAKES FAIL TO WORK PROPERLY. WHEN APPROACHING A STOP SIGN AND APPLYING THE BRAKES TO SLOW TO A STOP, THE BRAKES FAIL TO ENGAGE PROPERLY SO IT'S LIKE YOU'RE FLOATING UNCONTROLLABLY WHILE APPROACHING THE INTERSECTION AND IT FEELS LIKE YOU WILL NOT BE ABLE TO STOP IN TIME THEN ALL OF A SUDDEN IT WILL STOP, CAUSING EVERYONE AND EVERYTHING WITHIN THE VEHICLE TO LURCH (OR FLY) FORWARD. IN COLD WEATHER, WHEN APPLYING THE BRAKES TO SLOW TO A STOP, THE BRAKES SHUDDER AND FAIL TO ENGAGE CAUSING ONE TO LOSE CONTROL OF THE VEHICLE BRIEFLY I.E. CAN'T BRAKE, CAN'T STEER, CAN'T STOP EVEN THOUGH THERE'S NO ICE. I HAVE HAD THESE PROBLEMS PERIODICALLY SINCE PURCHASING THE VEHICLE IN 2005. I THOUGHT IT WAS SOMETHING I WAS DOING WRONG UNTIL RECENTLY WHEN I READ ABOUT OTHER PEOPLE EXPERIENCING THE SAME PROBLEMS. I AM CONCERNED I WILL BE UNABLE TO STOP IN TIME AT SOME POINT CAUSING AN ACCIDENT. *TR

SLOWING AS I APPROACHED A FOUR-WAY STOP, MY BRAKES FAILED TO STOP. I HEARD A LOUD NOISE (MY HUSBAND, A MECHANICAL ENGINEER SAYS IT IS THE ANTI-LOCK BRAKES) AND THE BRAKES DON'T WORK. ON THE FOURTH BRAKING ATTEMPT THEY WORKED. THIS IS THE THIRD TIME THIS HAS HAPPENED. EACH TIME WAS AT A SLOW SPEED, AFTER A RAIN, BUT NOT RAINING. *TR

LAST YEAR I WAS DRIVING MY 2005 TOYOTA SIENNA, AND A LINE OF DUCKS WALKED OUT IN FRONT OF MY CAR. I SLAMMED ON THE BRAKES BUT THE CAR JUST KEPT GOING, RUNNING OVER A DUCK AND STOPPING ABOUT 30 FT LATER. I THOUGHT MAYBE I WAS TOO SLOW TO BRAKE. THEN A COUPLE OF WEEKS LATER A MAN WALKED OUT FROM BEHIND A TRAILER AND I TRIED TO SLAM ON THE BRAKES (I WAS ONLY GOING ABOUT 20 MPH). THE MAN SAW ME AND HAD TIME TO GET OUT OF THE WAY THANKFULLY SINCE THE CAR DIDN'T STOP UNTIL 10 FT AFTERWARDS. I BROUGHT THE CAR TO MY DEALER AND THEY SAID 'THE MASTER CYLINDER IS BYPASSING' AND REPLACED IT. I DON'T HAVE THE OLD PART. HOWEVER, I WANTED TO MAKE SURE YOU KNEW ABOUT IT, BECAUSE IT WAS NOT OBVIOUS DURING NORMAL DRIVING, ONLY WHEN I HAD TO STOP QUICKLY. AND SOMEONE COULD EASILY HAVE BEEN KILLED. *TR

I PURCHASED A NEW 2005 TOYOTA SIENNA MINIVAN FROM A LOCAL DEALER IN 2005. AT 15,000 MILES THE DEALERSHIP REPLACED ALL 4 ROTORS/BRAKE PADS/TIRES UNDER WARRANTY. SINCE THEN ABOUT EVERY 10,000 - 20,000 MILES THE VEHICLE NEEDS NEW ROTORS AND BRAKE PADS. WE NOW HAVE 61,000 MILES ON IT AND ARE ON OUR FOURTH SET OF PADS AND ROTORS. THE DEALER CLAIMS THIS IS "NORMAL WEAR AND TEAR", BUT THIS IS THE WORST PERFORMANCE I HAVE EVER HEARD OF FROM A BRAKING SYSTEM. *TR

WE HAVE A 2005 TOYOTA SIENNA MINI-VAN. AT 16000 MILES, IT HAD A ROUTINE CHECK AND WAS FOUND TO HAVE A STUCK CALIPER IN THE FRONT AND SO THE DEALER REPLACED ALL FOUR ROTORS, BRAKE PADS, AND TIRES. NOW AT 52000, THE VAN WAS TAKEN IN FOR INSPECTION AND FOUND TO NEED ALL FOUR ROTORS, BRAKES PADS, AND TIRES REPLACED AGAIN. WE CHECKED SOME WEB SITES AND FOUND MANY PEOPLE WITH SIMILAR ISSUES WITH THE SIENNA. I CONTACTED TOYOTA AND THEIR RESPONSE IS THAT THIS IS NORMAL WEAR AND TEAR. I HAVE HAD MANY VEHICLES AND HAVE NEVER HAD TO REPLACE THESE ITEMS EVERY 30,000 MILES OR SO. *TR

OUR PASSENGER-SIDE SLIDING REAR DOOR HAS FROZEN IN PLACE AND WILL NOT OPEN. IT IS A 2005 TOYOTA SIENNA C MODEL. WE HAVE HAD OTHER ISSUES AS WELL, SUCH AS THE REAR HATCHBACK SUPPORTS FAILED WITHIN 3 YEARS, OUR DRIVERS-SIDE FRONT DOOR MAKES A POPPING SOUND WHEN OPENED, WE HAVE REPLACED THE FRONT BRAKES THREE TIMES WITHIN 65,000 MILES, AND SEAT BELTS THAT CONSTANTLY STICK. *TR

TL*THE CONTACT OWNS A 2005 TOYOTA SIENNA. WHILE DRIVING BETWEEN 5-6 MPH, ANOTHER VEHICLE RAN A STOP SIGN AND STRUCK THE LEFT REAR DRIVER'S SIDE OF THE CONTACT'S VEHICLE. HER VEHICLE FISH-TAILED AND TURNED TO THE LEFT. THE VEHICLE ACCELERATED AND STRUCK ANOTHER VEHICLE. THE CONTACT HAD NO CONTROL OVER THE VEHICLE. SHE ATTEMPTED TO PLACE THE VEHICLE INTO PARK, BUT WAS UNSUCCESSFUL. THE ENGINE REVVED AND THE VEHICLE ACCELERATED AGAIN. THE VEHICLE STRUCK A CURB, A BOULDER, AND THEN A PALM TREE BEFORE COMING TO A COMPLETE STOP. THE BRAKES FAILED TO OPERATE DURING THE INCIDENT. A POLICE REPORT WAS FILED AND THERE WERE NO INJURIES. THE VEHICLE WAS TOWED TO A GMC DEALER AND THEY TEST DROVE THE VEHICLE, BUT WERE UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE IS STILL AT THE GMC DEALER AND WILL BE APPRAISED. THE FAILURE AND CURRENT MILEAGES WERE 40,000. UPDATED 5/7/09 *CN UPDATED 05/11/09.*JB

I WAS TRAVELING THIS PAST TUESDAY, MAY 1ST, AND I NOTICE A SLIGHT NOISE FROM THE INSIDE OF MY VAN WHEN I HAD REACHED MY DESTINATION. IT HAPPENED WHEN I APPLIED MY BRAKES BUT WHEN I ROLL DOWN MY WINDOW I HADN'T NOTICED ANY NOISE FROM THE OUTSIDE OF THE VAN. I WAS ALONE AND DID GET OUT AND I HADN'T NOTICED ANYTHING IN OR AROUND THE FRONT LEFT TIRE. I HAD TO TRAVEL ANOTHER 1 AND A HALF BACK HOME AND BY THIS TIME MY CAR WAS MAKING A HORRIBLE NOISE. I HAD A MECHANIC LOOK AT THE CAR AND INFORMED ME THAT THE ROTOR WAS MESSED UP AND THE BRAKES WHERE METAL TO METAL. I ONLY HAVE 29,000 MILES ON MY VAN AND HE TOLD ME THAT THIS SHOULDN'T BE DOING THIS UNTIL ITS DUE TO A DEFECT SUCH AS A BAD CALIPER OR THE BRAKES WHERE GETTING HUNG UP. I CALLED TOYOTA AND THEY TOLD ME THAT THEY WOULD CORRECT THIS PROBLEM UNTIL I ARRIVED AND THEN THEY TOLD ME THAT THIS IS NORMAL FOR TOYOTA SIENNA MINIVANS. I AM CONCERNED THAT THERE IS MORE TO THE PROBLEM BECAUSE MY BRAKES NEVER SQUEALED OR SQUEAKED AND ITS ONLY ON THE LEFT SIDE. *TR

I BROUGHT MY 2005 SIENNA IN FOR NORMAL SERVICE AT 7500 MILES. THE TECHNICIAN INFORMED ME THAT I NEEDED MY BRAKES REPLACED. THIS IS OUTRAGEOUS TO ME. WAY BELOW WHAT IS TO BE EXPECTED. *NM

REAR BRAKES, BOTH, PADS COMPLETELY WORN AWAY OR SEPARATED FROM BACKING PLATE. THE VEHICLE HAS ONLY 22000 MILES ON IT. IN MY TYPE OF DRIVING, BRAKES NORMALLY LAST AT LEAST 40,000 MILES. FRONT BRAKES APPEAR TO BE OK, WEARING NORMALLY. *NM

DT*: THE CONTACT STATED WHILE DRIVING 40 MPH AND DEPRESSING THE BRAKE PEDAL, THE VEHICLE DID NOT STOP. THE PROBLEM OCCURRED ON THREE OCCASIONS. IT WAS MANEUVERED OFF THE ROAD AND COASTED TO A STOP. THE VEHICLE WAS TOWED TO THE DEALER WHO COULD NOT DUPLICATE THE PROBLEM.

I HAVE A 2005 TOYOTA SIENNA VAN THAT HAS INTERMITTENT BRAKE FAILURE. IT NORMALLY OCCURS WHEN THE CAR IS COLD. I HAVE RUN SEVERAL RED LIGHTS WITH THE BRAKE PEDAL PRESSED COMPLETELY TO THE FLOOR AND MY WIFE HAS DRIVEN THROUGH TWO YARDS. THE BRAKES FUNCTION NORMALLY ON THE FIRST SEVERAL APPLICATIONS BUT ON THE THIRD OR FOURTH APPLICATION THEY WILL OCCASIONALLY FAIL. MY DEALERSHIP HAS REPLACED THE MASTER CYLINDER AND DONE "DIAGNOSTICS" AT LEAST 8 DIFFERENT TIMES BUT CONSISTENTLY FIND NOTHING. THEY DID TELL ME THAT OTHER VEHICLES WERE EXPERIENCING THE SAME SORTS OF PROBLEM AND IT HAD SOMETHING TO DO WITH A NEW VALVE TIMING ON THE 2005 MODEL AND THE VACUUM WAS INSUFFICIENT UNTIL THE CAR WAS WARM AND THAT I SHOULD IDLE FOR 5 MINUTES BEFORE DRIVING. THIS SEEMS TO WORK MORE CONSISTENTLY BUT I STILL HAVE EPISODES OF POOR BRAKING. WE HAVE BEEN ATTEMPTING TO HAVE THIS RESOLVED FOR ALMOST 18 MONTHS. *JB

I HAVE A 2005 SIENNA XLE LIMITED AWD AND NOTICED FOR THE PAST TWO WINTERS THAT WHEN I START DRIVING THE CAR AFTER A COLD NIGHT, THE FIRST FEW TIMES I USE THE BRAKES THEY'RE NOT RESPONSIVE. IN FACT I CANNOT SEEM TO BE ABLE TO APPLY THE BRAKES SUFFICIENTLY HARD TO BRING THE CAR TO A STOP IF NEEDED (FROM MY HOUSE I HAVE A STEEP DOWNHILL AND THEN A STOP SIGN BEFORE CONTINUING ON A LARGER STREET.) HAVE NOTICED THIS ALSO IN OTHER PLACES/DIFFERENT CIRCUMSTANCES. BROUGHT UP THIS ISSUE WITH THE SERVICE ADVISOR WHO TOLD ME THAT THEY COULD NOT REPLICATE THE PROBLEM (LEFT THE CAR OVERNIGHT AT THE DEALERSHIP TWICE ALREADY). HE SAID THAT THE BRAKES FUNCTION PROPERLY. NEVERTHELESS, EVERY COLD MORNING I NOTICE THE SAME PROBLEM. *NM

WHEN TRYING TO STOP BRAKE PETAL WENT TO THE FLOOR. *TS THE VEHICLE WOULD NOT STOP AND THE CONSUMER VEHICLE COLLIDED WITH ANOTHER VEHICLE WHICH WAS STOPPED AT THE STOP LIGHT. THE VEHICLE WAS TOWED TO THE DEALER AND THE BRAKE SHOES AND PADS WERE INSPECTED. THE DEALER ALSO BLED THE BRAKES AND FOUND AIR IN ALL THE LINES EXCEPT THE RIGHT REAR. THE CONSUMER ASKED THE DEALER HOW AIR GOT IN THE LINES AND THEY REPLIED THAT THEY DIDN'T KNOW. *NM

I CONSUMER OWNS A SIENNA CE 2005. BOUGHT IT AT TOYOTA OF ORANGE ON MARCH 4,2005. VAN HAD A OIL CHANGE SERVICE ON AUGUST 13,05. ALTHOUGH MY VAN HAS LOW MILEAGE, ABOUT 1, 355 MILES AFTER OIL CHANGE. WENT SHOPPING AT RALPH SUPERMARKET IN FRONT OF TOYOTYA DEALER. WHEN WERE ABOUT TO GO HOME SUDDENLY BRAKES DID NOT WORK. LUCKILY VAN WAS STILL IN PARKING LOT OF RALPH SUPERMARKET. IMAGINE THAT IF THIS HAPPENED ON THE STREET CONSUMER AND CHILDREN COULD GET HURT OR KILLED. THEN CONSUMER CAREFULLY BACK TO DEALER AND LEFT VAN FOR SERVICE. IT'S ABOUT 7:30 PM - 08/13/05. CURRENTLY, VAN WAS STILL IN SERVICE DEPT FOR WAITTING FOR PART. ALREADY REPORTED BRAKE PROBLEM TO THE TOYOTA MANUFACTURER. WONDERED WHY SYSTEM DIDN'T SHOW THE BRAKE FAILURE? W VAN HAD BRAKE PROBLEM WHLIE IT WAS 5 MONTHS OLD AND STILL HAD LOW MILEAGE? AFTER FIXING THE BRAKE PROBLEM IS IT SAFE TO DRIVE THAT VAN? WISHED DID NOT HAVE THAT SERIOUS PROBLEM AGAIN. THAT'S ALL WAS CONSUMER'S CONCERNS. THANK YOU VERY MUCH FOR LISTENING. TU LE.714-542-4782. P.S: IDON'T KNOW EXACT MECHANICAL TERM TO DESCRIBE THE BRAKE PROBLEM AT THE BOTTOM OF THIS COMPLAINT. ONLY KNOW VAN HAS NO BRAKES AT THAT INCIDENT*AK.

I WAS BACKING OUT OF A PARKING SPACE IN A PARKING LOT. I PUT THE CAR IN REVERSE, PLACE MY FOOT ON THE BRAKE, PUT THE CAR INTO DRIVE, LIFTED MY FOOT OFF OF THE BRAKE AND THE CAR IMMEDIATELY BEGAN TO ACCELERATE WITHOUT MY FOOT EVEN TOUCHING THE ACCELERATOR. WHEN I PUT MY FOOT ON THE BRAKE, THE BRAKE PEDAL WENT ALL THE WAY DOWN TO THE FLOOR WITHOUT STOPPING THE VEHICLE. THE VAN STRUCK ANOTHER VEHICLE THAT WAS PARKED IN THE PARKING LOT, WENT OVER THE CURB OF THE PARKING LOT, DOWN AN EMBANKMENT INTO A RAVINE AND HEADED TOWARDS A TREE. THE PASSENGER THAT WAS IN THE FRONT SEAT THEN REACHED OVER AND PUT THE CAR INTO PARK, WHICH BROUGHT THE CAR TO A STOP. THE WHOLE TIME THE CAR WAS MOVING I WAS TRYING TO STOP THE CAR BY PUMPING THE BRAKES, BUT THEY DID NOT WORK. THE CAR WAS ACCELERATING THE ENTIRE TIME UNTIL THE PASSENGER STOPPED IT BY SHIFTING INTO PARK. THE AIRBAGS DID NOT DEPLOY. DAMAGE WAS DONE TO THE FRONT PASSENGER BUMPER AND SIDE OF THE CAR, THE DRIVER'S SIDE FRONT TIRE EXPLODED. AFTER THE ACCIDENT, THE BRAKES DID FUNCTION.

WHEN BRAKING HARD AT HIGHWAY SPEED BRAKES APPLY TO MUCH BACK PRESSURE, CAUSING THE VEHICLE BRAKES TO SEEM DEFECTIVE. I ALMOST CRASHED. *AK

EVER SINCE THIS VEHICLE WAS BRAND NEW IT HAS CONTINUED TO EXHIBIT OCCASIONAL PROBLEM WITH BRAKE PEDAL BECOMING HARD, WITH LITTLE OR NO PLAY, NECESSITATING THE NEED TO PUSH VERY HARD ON THE BRAKE PEDAL TO AFFECT STOPPING. NORMALLY THE BRAKES ARE VERY GOOD. THERE DOES NOT APPEAR TO BE ANY PARTICULAR CAUSE FOR THIS I.E. PADS BEING WET, ROAD SALT, ETC. IT ONLY OCCURS OCCASIONALLY AND SEEMS TO GO AWAY AFTER DRIVING FOR 20-30 MILES. WHEN IT DOES OCCUR THOUGH IT IS DIFFICULT TO STOP.
