2008 TOYOTA SIENNA Vehicle Speed Control Problems

Throttle stuck while in reverse pulling out of a parking spot and accelerated resulting in backing into the building

I have had the traction control go on while driving on the highway even when I turn it off. Sometimes the VSC and TRAC OFF lights go on while driving. The roads are dry. Whenever I take it in to the mechanic, all the lights are off. They pulled a zero calibration code and recalibrated. It still kept happening. Then I was driving around a curve on highway speeds when the traction control light went on and the van suddenly braked on its own and I almost lost control. The tires are new and the roads were dry.

Anti skid/slip malfunctions, Brakes are automatic applied while turning a corner. When this happen one dry road surfaces it was harder to control the car. This happen multiple times in the pass. Yes my safety and others on the road was put at risk. Yes been confirmed by independent service centers. 4.) UNKNOWN 5).No. The warning indicator light and buzzer comes on at the time the incident happens.

2008 Toyota Sienna. Driving down steep right turns, VSC light comes on, urgent beeping alarm and tires grip and grip vehicle brakes going 20-30+ mph on dry road. Very scary and dangerous, and has continues repeatedly over the past year on curvy right turns. Local mechanics don't know what is wrong with the vehicle. Many Sienna owners have similar problems listed on Carguru. https://www.cargurus.com/Cars/Discussion-c9152_ds656326 Please insist on a manufacturing recall for this vehicle. It is unsafe and could easily cause an accident. Thank you. Concerned original car owner.

BRAKES HAVE BEEN REPLACED, AND CHECKED SEVERAL TIMES MAKE A LOUD GRINDING NOISE IN WET WEATHER WHEN BACKING UP AND SOMETIMES WHEN APPLYING PRESSURE WHILE DRIVING ALSO A 🔊 NOISE AND BRAKES SEEM TO SLIP HAVE HAD TO PULL OVER BECAUSE IT SCARES ME CAN NOT FIND ANYTHING WRONG BUT CONTINUES TO PERSIST. BOTH IN HIGHWAY DRIVING AND REGULAR STREET DRIVING

WHILE ON AN ON-RAMP; THE VEHICLE AT ABOUT 35 MPH STARTED BLINKING THE SLIP LIGHT AND SLOWED THE VAN DOWN, ALSO CAUSING I THINK THE BRAKES TO ENGAGE WITH FORCE. HAPPENS WHILE DRIVING NORMALLY AND ON RAMPS. I HAD THE RACK AND PINION REPLACED AND STILL HAS DONE THIS.

Mileage: 146,892

THE VEHICLE STABILITY CONTROL WILL UNEXPECTEDLY ENGAGE IN INSTANCES WHERE IT SHOULDN'T ACTIVATE. THE MOST COMMON IS A LONG, SLIGHT CURVE ON AT FREEWAY SPEEDS ON DRY PAVEMENT. THE SECOND MOST COMMON SCENARIO IS ACCELERATING TO ENTER THE FREEWAY. WHEN VSC ENGAGES, THE VEHICLE WILL LURCH TO THE SIDE IT WAS ACTIVATED ON AND CURTAIL ANY ACCELERATION. THIS MAKES THE VEHICLE HARD TO CONTROL WHEN ON A FREEWAY CURVE AND WHEN ATTEMPTING TO ACCELERATE TO MERGE ONTO THE FREEWAY, CAUSING UNEXPECTED MOTION THAT IS A HAZARD TO REMAINING ON THE ROAD OR CAUSING THE VEHICLE TO BE IN AN ACCIDENT WITH OTHER VEHICLES. THERE IS NO INDICATION THAT THERE ARE MALFUNCTIONS IN ANY SYSTEM THAT WOULD CAUSE THIS TO OCCUR. NOTE: MILEAGE ON THE ODOMETER IS ~170,000 MILES.

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHEN THE CONTACT SWITCHED LANES OR MADE A TURN, THE BRAKES ACTIVATED ON THEIR OWN. THE FAILURE OCCURRED ON FLAT OR CURVED ROADS AND WHILE DRIVING 30 MPH. SOMETIMES THE BRAKES WORKED PROPERLY, BUT SOMETIMES THEY DID NOT WORK AT ALL. THE CONTACT ALSO STATED THAT THE VEHICLE WOULD OCCASIONALLY ACCELERATE AND DECELERATE ON ITS OWN AND THE STEERING WHEEL MADE AN ABNORMAL TICKING NOISE. FURTHERMORE, THE VSC AND TRACTION CONTROL INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO TOYOTA KNOXVILLE (10415 PARKSIDE DR, KNOXVILLE, TN 37922), BUT THEY DID NOT ASSIST. THE VEHICLE WAS THEN TAKEN TO FOX TOYOTA (228 FOX FAMILY LN, CLINTON, TN 37716) WHERE IT WAS DIAGNOSED THAT A STEERING ANGLE SENSOR NEEDED TO BE INSTALLED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES AND PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS 170,000. *BF *TR

OCTOBER 2016 THIS PROBLEM OF MY 2008 TOYOTA SIENNA STARTED- ON SLIGHT CURVES DOING 30-40MPH I WOULD HEAR A CLICKING NOISE COMING SOMEWHERE UNDERNEATH THE FRONT RIGHT END ALMOST AS IF UNDER THE DASH, THE VSC LIGHT WOULD FLASH. I TOOK TO A TOYOTA DEALERSHIP, HAD A MECHANIC TEST DRIVE WITH ME THEY SAID THE PROBLEM WAS THAT MY TIRES WERENT ALIGNED WITH MY LAST TIRE CHANGE(WHICH WAS DONE AT THEIR TOYOTA DEALERSHIP) TOYOTA TOLD ME I NEEDED TO REPLACE ALL THE TIRES AND HAVE THE WHEELS ALIGNED. I DID THIS, PROBLEM CONTINUED. I TOOK MY VAN IN AGAIN TO TOYOTA, THEY LIED AND TOLD ME I NEEDED NEW BRAKES, AND SOME OTHER THINGS I DIDNT NEED. DECIDED TO GET A 2ND OPINION FROM 2 OTHER AUTO SHOPS AND FOUND OUT TOYOTA LIED ABOUT THE BRAKES, THEY WERE FINE AND THEY BOTH WERE UNABLE TO FIND OUT MY PROBLEM. I FOUND THIS OUT GOING TO 2 OTHER AUTO SHOPS ASKING FOR THEM TO LOOK INTO THE ORIGINAL PROBLEM. NOW TODAY MAY 2019 THIS PROBLEM STILL EXISTS, BUT HAS GOTTEN WORSE. NOW-THE VSC LIGHT COMES ON, IT STILL CLICKS, THE ABS LIGHT AND WARNING SOUND GOES OFF, FEELS AS IF ABS ENGAGES, AS IT JERKS AND IM UNABLE TO ACCELERATE DURING THIS TIME UNTIL IM ON A STRAIGHT AWAY. VERY SCARY WHEN IT HAPPENS THE VAN STARTS JERKING AND UNABLE TO ACELERATE, NOT SAFE TO TAKE MY FAMILY IN. NEVER BUY ANOTHER TOYOTA AGAIN...

WE HAVE A 2008 TOYOTA SIENNA. THE VEHICLE HAS 174,000 MILES ON IT. THE VSC ICON COMES ON ALONG WITH THE ALARM WHEN DRIVING ON DRY ROADS AND WHEN TURNING WHETHER ON FLAT OR DOWNHILL TRAVEL WITH THE BRAKES GRABBING AND RELEASING. THE SITUATION IS UNPREDICTABLE. PROBLEM STARTED AT APPROXIMATELY 173,000. THE SLIP INDICATOR LIGHT STARTED COMING ON INTERMITTENTLY WHILE TURNING ON HIGHWAYS ETC. PLEASE MAKE THIS SERIOUS RECALL FOR TOYOTA. YOU NEED TO FORCE TOYOTA TO TAKE THIS SERIOUSLY BEFORE SOMEONE LOSES A LIFE. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THIS CAR IS EXPERIENCING SUA. IT HAPPENED IN A PARKING LOT AN RESULTED IN A CRASH INTO A CEMENT WALL. IT ALSO HAPPENED ON A WINDING MOUNTAIN ROAD.

Mileage: 141,000

PULLED INTO PARKING LOT AT ABOUT 15 MPH. WITH MY FOOT ON THE BRAKE, I SLOWED DOWN TO ABOUT 5 TO 10 MPH TO PULL INTO THE PARKING SPOT. ALL OF A SUDDEN, THE VEHICLE ACCELERATED AS IF SOMEONE HAD PUSHED THE ACCELERATOR ALL THE WAY TO THE FLOOR. MY VEHICLE WENT UP OVER THE SIDEWALK AND INTO THE SIDE OF A BUILDING CAUSING EXTENSIVE DAMAGE TO THE BUILDING. MY CAR WAS NOT DAMAGED TOO BADLY ONLY ABOUT $1,300 AS ESTIMATED BY THE APPRAISER. *TR

MY WIFE WAS PARKING OUR 2008 TOYOTA SIENNA WITH OUR 3 YOUNG BOYS IN THE AUTOMOBILE. SHE SLOWLY BROUGHT THE VEHICLE TO A COMPLETE STOP; NEVER USING GAS, JUST COVERING AND TAPPING LIGHTLY ON THE BRAKE. ONCE THE AUTOMOBILE CAME TO A STOP MY WIFE PRESSED THE BRAKE A LITTLE MORE IN ORDER TO PUT THE VEHICLE IN PARK. AT THAT MOMENT THE VEHICLE ACCELERATED INCREDIBLE FAST, JUMPED OVER AN 8 INCH CONCRETE PARKING LOT DIVIDER AND CRASHED INTO A TREE ABOUT 10 - 15 FEET FROM THE CONCRETE DIVIDER. WE ARE CERTAIN THAT THIS WAS A "SUDDEN UNINTENDED ACCELERATION" INCIDENT CAUSED BY SOME MECHANICAL, ELECTRICAL, PROGRAMMING OR OTHER DEFECT IN THE '08 SIENNA. THIS WAS NOT "DRIVER ERROR"! MY WIFE DID NOT CONFUSE THE GAS PEDAL AND THE BRAKE. THIS WAS NOT CAUSED BY A FLOOR MAT OBSTRUCTING THE GAS PEDAL. THIS WAS CAUSED BY SOME TYPE OF A DESIGN OR COMPONENT DEFECT. HOW CAN W BE SO CERTAIN? MY WIFE AND I HAVE PARKED IN THIS PARKING SPOT (LOCATED IN OUR APARTMENT COMPLEX) HUNDREDS OF TIMES. TO PARK IN THIS PARKING SPOT YOU FIRST HAVE TO MAKE A LEFT HAND TURN AT A STOP SIGN. THIS STOP SIGN IS ABOUT 30 - 40 FEET FROM THE PARKING SPOT, WHICH REQUIRES THAT YOU MAKE A SHARP RIGHT TURN. ONCE YOU PRESS THE ACCELERATOR SLIGHTLY TO MAKE THE LEFT AT THE STOP SIGN, YOU DO NOT USE THE GAS AGAIN. YOU SIMPLY TAP AND COVER YOUR BRAKE UNTIL YOU MAKE THE RIGHT INTO THE PARKING SPOT. OUR VEHICLE CAME TO A STOP. IN FACT, UPON "STOPPING" ONE OF OUR 3 BOYS REMOVED HIS SEAT BELT IMMEDIATELY BEFORE THE VEHICLE ACCELERATED OUT OF CONTROL. I'M ASKING FOR ASSISTANCE FROM SOMEONE WITHIN TOYOTA OR THE NHTSA WITH KNOWLEDGE OF THIS FLAW. MY WIFE AND KIDS WERE "FORTUNATE". BUT THIS IS A "FATAL FLAW" AND SOMETHING MUST BE DONE. *TR

JUST NOTIFIED OF SUDDEN ACCELERATION. HINDSIGHT - STARTING FALL 2012 REMOTE STARTER DIED,NO WARMUP,MY BOYFRIEND AND I EXPERIENCED ENGINE RACING WHEN VAN WAS COLD MULTIPLE TIMES,ONLY WAY TO STOP IT WAS HAND CONTROL BRAKE,FOOT BRAKE WAS NOT ENOUGH.

I AM PARAPLEGIC,MY MINIVAN IS MODIFIED WITH FOLDOUT RAMP- PASSENGER SIDE SLIDING DOOR FOR WHEELCHAIR AND THEN I TRANSFER INTO THE DRIVERS SEAT. ALL THE VAN HANDICAPPED PARKING SPACES WERE FILLED BUT IT WAS EARLY SO I PARKED IN A REGULAR SPACE WITH AN EMPTY SPACE NEXT TO IT SO I COULD GET OUT. FEW VAN ACCESSIBLE HANDICAPPED SPACES IS COMMON SO I USED REGULAR SPOTS BEFORE AS LONG AS SOMEONE WAS WITH ME WHO COULD BACK THE VAN UP FAR ENOUGH FOR THE RAMP TO DEPLOY. WHEN MY MOTHER,MY SISTER-IN-LAW,MY FRIEND,AND I RETURNED TO THE VEHICLE A PICKUP TRUCK WAS PARKED NEXT TO US. MY SISTER-IN-LAW GOT IN THE VEHICLE TO BACK IT UP SO THE RAMP HAD ROOM TO COME OUT AS SHE HAD DONE OFTEN. WE STOOD BEHIND THE PICKUP TRUCK WAITING FOR HER TO BACK UP.

MY SISTER-IN-LAW WAS COMPLETELY SHOCKED AS WERE WE, IT WAS SO FAST IT WAS ALMOST LIKE WATCHING A CARTOON. MY SISTER-IN-LAW KEPT SAYING "I DON'T KNOW WHAT HAPPENED", SHE THOUGHT ALL SHE DID WAS PUT HER FOOT ON THE BRAKE AND PUT IT IN GEAR. NOT KNOWING ABOUT SUDDEN ACCELERATION IN SIENNA'S ALL ANY OF US COULD THINK WAS HER FOOT HAD SLIPPED EVEN THOUGH SHE HAS BEEN DRIVING FOR 25 YEARS WITHOUT A SIMILAR INCIDENT SHE COULDN'T UNDERSTAND HOW IT COULD HAPPEN, WAS SURE IT DIDN'T. THE POLICE WERE CALLED AND A REPORT FILED. BECAUSE ONE OF THE WELDS FROM MODIFICATION WAS BROKEN MY VEHICLE WAS TOTALED. *TR

IS TRYING TO CATCH UP WITH THE DEPRESSED ACCELERATION PEDAL. THIS HAS OCCURRED AT VERY INAPPROPRIATE TIMES, WHERE WE WOULD HAVE TO SUDDENLY APPLY THE BRAKES ABRUPTLY. THE NATURE OF THE DEFECT IS UNUSUAL AND NOT ONLY POSES A SAFETY PROBLEM WHILE THE VEHICLE IS LUNGING, BUT ALSO POSES A SERIOUS SAFETY ISSUE, IF WE WERE TRYING TO MERGE ON A LIMITED ACCESS HIGHWAY. BEING THAT A VEHICLE TRAVELING ON A LIMITED ACCESS HIGHWAY MAY BE TRAVELING AT 60 MPH. THAT VEHICLE WILL TRAVEL APPROXIMATELY 176 FEET IN THAT TWO SECOND LAG TIME OF OUR VEHICLE?S ACCELERATION SYSTEM. *TR

1. ENGINE LIGHTS CAME ON ALERTING US TO A PROBLEM (CHECK ENGINE, SERVICE ENGINE, ETC.). AFTER ALLEGED REPAIR, SPOUSE DROVE TO FAMILIES HOUSE APPROXIMATE 600 MILES AWAY AND FOUND A SIGNIFICANT AMOUNT OF OIL HAD LEAKED FROM THE SYSTEM - OIL HAD BEEN CHANGED AS PART OF THE FIX. A SECOND DEALER, AT THE NEW LOCATION, "FIXED" WITH THE SAME HOSE AGAIN, WITH SIMILAR RESULTS, THOUGH MY SPOUSE ONLY DROP 120 MILES. SHE IS UNABLE TO CONTINUE THE TRIP HOME DUE TO THIS ISSUE. 2. AFTER TAKING TO DEALER, WAS TOLD THE VVT OIL LINE WAS A KNOWN FAULTY PART AND NEEDED REPLACEMENT. WAS NOT A "FORMAL" RECALL, BUT WAS CONSIDERED AN INTERNAL RECALL TO TOYOTA THAT NEEDED TO BE FIXED FOR "FREE". BOTH DEALERSHIPS CLAIMED TO HAVE FIXED THE PROBLEM, THOUGH THE ENGINE IS STILL LEAKING A SIGNIFICANT AMOUNT OF OIL. THERE IS A SIGNIFICANT AMOUNT OF DATA ON THE WEB THAT ADDRESSES THIS OIL LINE AND THE ASSOCIATED ISSUES. 3. PART WAS REPLACED, BUT WITH SAME TYPE (PART NUMBER, COMPOSITION, ETC.). BASICALLY, A "NEW" BAD PART WAS REPLACED. FURTHERMORE, THE FIRST DEALERSHIP INSTALLED VARIOUS GASKETS AND SEALS INCORRECTLY, AND STILL GAVE THE CAR A SAFE RATING FOR A 600 MILE TRIP.

THIS HAPPENED YESTERDAY JULY 10, 2010 SATURDAY IN THE REGIONAL PARKS PARKING LOT. SINCE IT'S UNPAVED SO THERE WAS ROCKS AND DIRT ON THE GROUND SO I WAS DRIVING EXTREMELY SLOW TO COME TO A STOP AT A SPOT TO PARK ' I WAS DRIVING WAY BELOW 5 MPH AND EVEN SLOWER WHEN I WAS ABOUT TO COME TO STOP ' AS I ALSO KNOW OUTSIDE OF THE WIRE FENCE, BEYOND THE NARROW ROAD, IT WAS A CLIFF WITH A SUBSTANTIAL DROP OF ELEVATION; AND I HAVE MY WHOLE FAMILY IN THE CAR. I WAS DRIVING A TOYOTA SIENNA MINI VAN WHICH I HAVE BEEN A LOYAL CUSTOMER AND A BIG BELIEVER OF THE QUALITY. JUST AROUND THE TIME THE CAR IS ABOUT TO STOP, ALL OF A SUDDEN, IT SPED UP FORWARD IN SUCH A FORCE WE WERE ALL PUSHED BACK AGAINST THE SEAT BACK, I IMMEDIATELY MOVED MY FOOT TO THE BRAKE AND PRESS ALL THE WAY BUT IT WAS NOT RESPONSIVE AND DID NOT SLOW THE CAR. INSTEAD, THE CAR SPED UP AND WENT THROUGH THE WIRE FENCE AT ABOUT 45 DEGREE ANGLE, WHILE I WAS STEERING TOWARDS LEFT TO AVOID IT WITH VERY LITTLE EFFECT, AND DROPPED DOWN THE SLOPE ONTO THE ROAD, ALL THE WHILE KEPT SPEEDING UP, AND THEN GOT ACROSS THE ROAD AND HIT A WOODEN POLE ON THE ROAD SIDE BY THE CLIFF STRAIGHT ON. THEN THE CAR STOPPED AND THE BRAKE SEEMED TO WORK AGAIN AS MY RIGHT FOOT WAS PUSHING ALL THE WAY DOWN ON THE BRAKE FOR THE WHOLE TIME ' SO I SHIFTED TO PARK, TURNED OFF THE ENGINE, AND THEN OPEN THE DOOR TO TELL PEOPLE COMING UP THAT WE WERE FINE. SOMEONE CALLED THE HIGH WAY PATROL AND THE OFFICER ARRIVED LATER TO TAKE THE CASE AND LATER TRANSFER THE CASE TO THE PARK POLICE FOR REPORT. THE CAR WAS TOWED TO A BODY SHOP AND MOST LIKELY IS TOTALED. WE HAVE INSURANCE COVERAGE SO THE FINANCIAL DAMAGE TO US WASN'T BIG. BUT WE ARE REALLY CONCERNED OF WHAT HAS HAPPENED. WE WERE SO LUCKY TO HAVE ESCAPED THE DROP DOWN THE CLIFF AND EXTREMELY LUCKY THAT WE DID NOT HIT ANYONE ALONG THE WAY, EVEN THOUGH IT WAS ONLY A FEW SECONDS (MAYBE 3-5 SECONDS) BUT THIS WAS A CROWDED PARK AND THERE WERE MANY BIKERS BIKING ALONG THE ROAD. *TR

I HAVE A 2008 TOYOTA SIENNA AWD. SATURDAY AFTERNOON I WAS DRIVING EAST ALONG LEE HIGHWAY IN ARLINGTON, VA (PROBABLY MOVING AT ABOUT 30 TO 35 MPH) WITH MY TWO SMALL CHILDREN, AND I SLOWED AS I APPROACHED THE INTERSECTION WITH HARRISON STREET (WHICH IS A RATHER BUSY INTERSECTION). MY TRAFFIC LIGHT WAS RED, SO I NEEDED TO STOP. I APPLIED THE BRAKES FULLY, AND THE CAR CONTINUED TO SLOW, BUT IT DID NOT STOP FULLY. I RELEASED THE BRAKE AND THEN PUSHED IT HARD ALL THE WAY TO THE MAT, BUT THE CAR STILL CONTINUED TO INCH FORWARD. I BECAME FRIGHTENED AND THREW THE CAR INTO PARK AND HIT THE EMERGENCY BRAKE. THE CAR SEEMED TO STOP, BUT I TURNED OFF THE IGNITION JUST IN CASE. I WAS A FEW MINUTES FROM HOME, SO I DROVE HOME WITH MY HAZARDS ON AND PARKED THE CAR. I HAVE NOT DRIVEN IT SINCE. I CALLED THE DEALERSHIP THAT HAS BEEN PRIMARILY SERVICING THE VEHICLE (KOONS ARLINGTON), AND WAS TOLD TO CALL TOYOTA HEADQUARTERS - 800.331.4331. I CALLED THIS NUMBER FOR HEADQUARTERS, BUT AFTER REMAINING ON HOLD FOR OVER 5 MINUTES WITH NO END IN SIGHT AND WITHOUT HEARING A LIVE PERSON, I HUNG UP AND TRIED THE DEALERSHIP AGAIN. A SERVICE REPRESENTATIVE TOLD ME TO HAVE THE VEHICLE TOWED TO THE DEALERSHIP, WHICH I DID EARLY THIS MORNING. I AM AWAITING A RESPONSE FROM THE DEALERSHIP.

2008 TOYOTA SIENNA ACCELERATION HESITATION THIS MINIVAN HESITATES FROM DRIVER ACCELERATION FOR 1-2 SECONDS INTERMITTENTLY AT VERY LOW SPEEDS. HOWEVER, THE PROBLEM CAN BE REPRODUCED VERY EASILY BY MAKING A CORNER TURN AT LOW SPEED, AND INCREASING ACCELERATION AFTER THE TURN. THE MINIVAN WILL NOT RESPOND FOR 1-2 SECONDS BEFORE 'JUMPING' INTO THE ACCELERATION. THE BIGGEST SAFETY ISSUE WITH THIS IS A LEFT TURN ACROSS AN ONCOMING LANE OF TRAFFIC (SIMILAR TO A CORNER TURN). IF I AM COASTING TO THE INTERSECTION FOR THE TURN, THE MINIVAN DOES NOT RESPOND TO THE DRIVER INPUT FOR ACCELERATION TO GET OUT OF THE WAY OF THE ONCOMING CAR (UNTIL THROUGH THE INTERSECTION). KNOWING THIS DEFECT, I COMPENSATE FOR IT, BUT AN UNSUSPECTING DRIVER COULD HAVE AN ACCIDENT WITH THIS DEFECT. *TR

ON APRIL 1, 2008, AT ABOUT 9:30 P.M., MY TWO SONS, 19 AND 16, AND MY YOUNGEST SON'S FRIEND DROVE SOUTH ON INTERSTATE 35 OUT OF DOWNTOWN MINNEAPOLIS UPON CONCLUSION OF A TWINS GAME. ABOUT THREE BLOCKS NORTH OF CROSSTOWN HIGHWAY 62, GOING 60 MPH I PASSED A CAR BY PUTTING THE ACCELERATOR ON THE FLOOR. TRAFFIC IS SOMEWHAT HEAVY OF COURSE. THE CAR CONTINUED ACCELERATING DESPITE THE FACT THAT I TOOK MY FOOT OFF OF THE ACCELERATOR. I CALMLY TOLD MY 19 YEAR OLD SON SITTING NEXT TO ME THAT THE ACCELERATOR WAS STUCK. HE SHIFTED THE CAR INTO NEUTRAL, AND THEN INTO PARK AND REVERSE WHEN THE SHIFT INTO NEUTRAL DIDN'T SEEM TO CORRECT THE PROBLEM. HE THEN SHIFTED THE CAR BACK INTO NEUTRAL, MY FOOT WAS ON THE BRAKE, AND I WAS ABLE TO SLOW THE CAR DOWN ON THE 80 DEGREE TURN ONTO THE CROSSTOWN 62 FROM I35. I SLOWED THE CAR DOWN TO ABOUT 45 MPH AND, LUCKILY, WAS ABLE TO GET TO THE SHOULDER. I TOOK THE CAR IN TO MY LOCAL MAINTENANCE SHOP THE NEXT DAY. THE OWNER OF THE SHOP SUGGESTED THAT I ASK THE DEALER I PURCHASED THE MINIVAN FROM, BLOOMINGTON TOYOTA, TO CHECK AT LEAST THE FOLLOWING THREE ITEMS: THROTTLE POSITION SENSOR, ENGINE CONTROL MODULE, AND IDLE CONTROL MOTOR. ON MAY 15, 2008, I BROUGHT THE MINIVAN INTO BLOOMINGTON TOYOTA AND TOLD THEM WHAT MY LOCAL SHOP OWNER SUGGESTED. AFTER TESTING THE VEHICLE, THE SERVICE MANAGER TOLD ME THAT THEY FOUND NOTHING WRONG WITH THE VEHICLE AND THAT IF THE ACCELERATOR HAD MALFUNCTIONED, THEIR COMPUTER TESTING DEVICES WOULD HAVE DETECTED IT AND HAD DETECTED NOTHING. *TR

I APPROACHED THE INTERSECTION OF CORTZ RD. AND 34 ST. IN BRADENTON, FL IN HEAVY TRAFFIC. THE TRAFFIC LIGHT CHANGED FROM RED TO GREEN, THE LINE OF TRAFFIC STARTED TO MOVE FORWARD. I APPLIED ACCELERATOR AND BRAKE AS NEEDED WITH TRAFFIC, THEN THE CAR IN FRONT OF ME STOPPED SUDDENLY ,I LET UP ON THE ACCELERATOR AND PRESSED THE BRAKE AND THEY DID NOT RESPOND AS THEY SHOULD HITTING THE CAR IN FRONT OF ME. THIS ALL RESULTED IN A 5 CAR CHAIN REACTION CRASH. IT SEEMED AS MY CAR WANTED TO KEEP ON GOING AS IF I HAD NOT DONE ANYTHING TO STOP. THIS IS THE SECOND TIME I HAVE HAD TROUBLE WITH ACCELERATION AND BRAKE CONTROL WITH THIS CAR IN JUST OVER 30 DAYS. THE CAR IS STILL IN THE REPAIR SHOP. I DO NOT HAVE ANY CONFIDENCE IN THIS CAR TO OPERATE CORRECTLY OR IN SAFE MANNER. TOYOTA HAS DONE NOTHING FOR ME TO FIX THIS PROBLEM. I HAVE TRIED TO CONTACT TOYOTA BY PHONE AND COMPUTER WITHOUT SUCCESS. I HAVE BEEN TO A TOYOTA DEALER TWICE AND THEY REFER ME TO TOYOTA CUSTOMER SERVICE PHONE NO. BECAUSE THE SIENNA MODEL IS NOT PART OF THE RECALL. HOWEVER WHEN I GO TO THE NHTSA.DOT.GOV WEB SITE THERE ARE SEVERAL CASES LISTED OF ACCELERATION PROBLEMS WITH THE SIENNA. PLEASE HELP. *TR

I OWN AND DRIVE A 2008 TOYOTA SIENNA. I PULLED OUT OF CAR WASH AND DROVE OVER TO A CAR VACUUM CENTER AT LESS THAN 5MPH. AS I APPROACHED THE VACUUM AREA I TOUCHED THE BRAKE AND THE CAR ACCELERATED FAST, RAN INTO A METAL POST ,METAL FENCE AND OVER A CURB ALMOST HITTING INDIVIDUALS IN THE AREA. THIS OCCURRED IN PALMETTO, FLORIDA. THIS CAR SEEMED TO HAVE A MIND OF ITS OWN. THERE DID NOT SEAM TO BE ANY REASON FOR THE ACCELERATION AT LEAST NOT FROM MY OPERATION. I HAVE TO DRIVE BACK TO FORT WAYNE, IN AND I'M CONCERNED ABOUT THE SAFETY OF THIS AUTO FOR ME AND MY WIFE AND ALL OTHER ON THE HIGHWAY. *TR

I OWN A 2008 SIENNA. THERE IS AN ACCELERATION PROBLEM THAT I CAN REPLICATE. IT OCCURS WHEN STOPPING AT THE BOTTOM OF AN INCLINE. ALTHOUGH SIENNA IS NOT ON THE RECALL LIST, IT SHOULD BE. IT OCCURS OFTEN, THE MAJORITY OF TIMES WHEN GOING DOWN A HILL. MY CONCERN IS THAT IT WILL OCCUR UNEXPECTEDLY. NO RESPONSE FROM TOYOTA ON THIS COMPLAINT. *TR

THIS IS A FOLLOW UP TO MY 2/4/2010 REPORT (ODI #10305864) ABOUT MY 2008 TOYOTA SIENNA. EVER SINCE I BOUGHT IT NEW IN FALL 2008, THERE IS NOTICEABLE MOMENTARY UNINTENDED ACCELERATION BRIEFLY WHENEVER I PRESS THE BRAKE PEDAL AT SPEEDS OF ABOUT 30-40 MPH. THEN THE BRAKE TAKES HOLD. I HAD NOT GIVEN MY VIN #. THIS TIME I WILL DO THAT. (THIS IS AN ONGOING PROBLEM THAT TOYOTA SERVICE SAYS IS NORMAL, DUE TO THE NATURE OF SIENNA'S TRANSMISSION) *TW *TR

WE DROVE FROM PEMBROKE TO NORTH CAROLINA, TAKING A FEW BREAKS IN BETWEEN TWO WEEKS AGO. WE PULLED INTO A SERVICE STATION TO USE THE REST ROOMS AND PURCHASE COLD DRINKS, IN ROANKE SPRINGS, NC. MY WIFE PULLED INTO A HANDICAPPED PARKING SPOT IN FRONT OF THE STORE. SHE WAS ONLY 10 FEET FROM STOPPING THE VEHICLE WHEN THE CAR ACCELERATED FORWARD AND FORTUNATELY CRASHED INTO A CONCRETE PILLAR OTHERWISE WE WOULD HAVE GONE DIRECTLY INTO THE STORE. THE SURGE OF THE CAR ACCELERATING PUSHED ME BACK INTO MY SEAT, PASSENGER. OUR VEHICLE TOYOTA SIENNA STRUCK THE CONCRETE PILLAR DIRECTLY IN THE MIDDLE OF THE FRONT END. I THEN REACHED DOWN AND TURNED THE CAR OFF. WE WERE TRAVELING WITH ANOTHER COUPLE, THEY HAD PARKED THEIR CAR AND HEARD THE SQUEAL OF THE BRAKES BEING APPLIED AND THEN THE CRASH OF OUR VEHICLE INTO THE CONCRETE PILLAR. THE CAR IS BEING REPAIRED IN ROANKE SPRINGS, NC AT THE BONES TOYOTA DEALER. WE THEN RENTED A VEHICLE AND CONTINUED OUR TRIP TO FLORIDA. *TR

ON JAN 29, 2010 MY 11 YRS. DAUGHTER AND I WERE TRAVELING IN OUR 2008 TOYOTA SIENNA SOUTH ON HWY 51/I39. THE ROADS AND WEATHER WERE BASICALLY DRY. I HAD JUST SET THE CRUISE ON 71MPH WHEN THE VEHICLE SURGED AHEAD, THE SPEEDOMETER SAID 80, AND WITHIN A MINUTE HAD REDUCED TO THE 71MPH I HAD SET. IT WAS VERY SUDDEN AND VERY SCARY TO BOTH OF US. THERE WAS NO FOOT ON THE ACCELERATOR AND NO FLOOR MAT WAS THE PROBLEM. I FEEL THIS IS A WARNING OF WHAT COULD HAPPEN AND THERE ARE DOCUMENTED C/O SINCE 2006 FOR SIENNAS THAT HAVE THIS SAME PROBLEM. *TR

I ACCIDENTALLY HIT THE CRUISE CONTROL IN MY 2008 TOYOTA SIENNA WHEN THE CONTROL LEVER WAS OVER THE WINDSHIELD WIPER CONTROL IN A SLIGHT LEFT TURN, RESULTING IN THE CRUISE CONTROL GOING UNEXPECTEDLY INTO "RESUME". BECAUSE OF INCLEMENT WEATHER I HAD SLOWED DOWN AND WAS NOT EXPECTING THE INSTANT ACCELERATION. TOOK A COUPLE SECONDS TO REALIZE WHAT HAD HAPPENED WHEN I HAD TRIED TO OPERATE THE WINDSHIELD WIPER CONTROL. THE TOYOTA CRUISE CONTROL LEVER MOUNTED ON THE STEERING COLUMN WHERE IT TURNS WITH THE WHEEL APPEARS TO BE A LESS THAN DESIRABLE ENGINEERING DECISION FROM A SAFETY STANDPOINT. TRYING TO EXPRESS THIS CONCERN TO MY LOCAL TOYOTA DEALER, (PINE BLUFF, ARKANSAS, WHERE I BOUGHT THE CAR) WAS UNSUCCESSFUL. I HAD BEEN TRYING TO BE HELPFUL WITH TOYOTA'S MORE GENERIC PROBLEM OF A COMPLAINT OF UNCONTROLLABLE ACCELERATION, WHICH TOYOTA HAS BEEN TRYING TO BLAME ON IMPROPER FLOOR MATS BEING JAMMED INTO THE ACCELERATOR PEDAL. *TR
