2006 Toyota Sienna Cruise Control Problems

AT SPEEDS OF ANYWHERE BETWEEN 30-60 MPH, TRACTION CONTROL SYSTEM ENGAGES WHEN TURNING SLIGHTLY LEFT. ALARM COMES ON, BRAKES ARE AUTOMATICALLY APPLIED. VERY DANGEROUS

WHEN DRIVING AT SPEEDS OF 38 MPH OR MORE AND TURNING THE STEERING WHEEL/TIRES, THE VSC WARNING ALARM WILL GO OFF. WHEN THIS HAPPENS, THE CARS AUTOMATICALLY BRAKES. THIS HAPPENS WHEN THERE ARE NO PROBLEMS WITH THE DRIVING CONDITIONS. THE SEVERITY OF THE BRAKING AND LENGTH OF ALARM VARY. IT IS ESPECIALLY PROBLEMATIC ON TIGHT TURNS. IT DOES NOT MATTER WHETHER YOU ARE GOING UPHILL, DOWNHILL, OR TURNING ON A FLAT ROAD. WE DO NOT KNOW WHAT IS CAUSING THIS UNSAFE ISSUE. WE HAVE TRIED TURNING OFF THE TRAC. IT MADE NO DIFFERENCE.

TL* THE CONTACT OWNED A 2006 TOYOTA SIENNA. WHEN THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE INDEPENDENTLY ACCELERATED TOWARDS AN INTERSECTION. AS A RESULT, THE CONTACT CRASHED INTO TWO OTHER VEHICLES. THE CONTACT'S VEHICLE CAME TO A STOP WHEN IT CRASHED INTO A POLE. THE CONTACT SUFFERED INJURIES TO THE BACK, NECK, SHOULDER, CHEST, KNEES, AND HIPS. THE PASSENGER SUFFERED INJURIES TO THE SHOULDER AND STOMACH. MEDICAL ATTENTION WAS RECEIVED. HUNTINGTON BEACH POLICE WAS AT THE SCENE AND FILED REPORT NUMBER: [XXX]. THE VEHICLE WAS TOWED. THE MANUFACTURER WAS CONTACTED AND PROVIDED CASE NUMBER: [XXX]. THE CONTACT ALSO STATED THAT THE MANUFACTURER'S ENGINEER WOULD INSPECT THE VEHICLE TO DETERMINE THE CAUSE OF THE FAILURE. THE VEHICLE WAS DESTROYED. THE APPROXIMATE FAILURE MILEAGE WAS 112,297.*PM ('PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).')*JB

TL* THE CONTACT OWNS A 2006 TOYOTA SIENNA. WHILE COASTING WITH TRAFFIC, THE VEHICLE'S ACCELERATOR PEDAL SUDDENLY TRAVELED TO THE FLOORBOARD, CAUSING THE VEHICLE TO ACCELERATE AT HIGH SPEEDS. THE ACCELERATOR PEDAL REMAINED DEPRESSED. THE CONTACT ATTEMPTED TO DEPRESS THE BRAKE PEDAL, BUT THE VEHICLE DID NOT STOP. THE CONTACT WAS ABLE TO MOVE THE VEHICLE OVER TO THE SIDE LANE AS IT CONTINUED TO ACCELERATE. THE CONTACT ENGAGED THE EMERGENCY BRAKE, WHICH CAUSED THE VEHICLE TO SLOW DOWN SLIGHTLY. THE CONTACT THEN MOVED THE GEAR SHIFT INTO THE PARK POSITION AND THE VEHICLE STOPPED VIOLENTLY. THE VEHICLE WAS TOWED TO A CERTIFIED MECHANIC. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER, BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 90,000.*DT *TR

MY SLIP INDICATOR LIGHT COMES ON AS I ROUND TURNS AND THE ENGINE SEEMS TO RPM DOWN. THIS HAPPENS AT NORMAL SPEEDS, ON DRY ROADS. UNABLE TO DRIVE ON THE HIGHWAY, BECAUSE WHEN SLIP INDICATOR LIGHT COMES ON, IT ALSO APPLIES THE FRONT BRAKES AT HIGHWAY SPEEDS. OTHER OWNERS OF TOYOTA SIENNA ARE ALSO HAVING THE SAME PROBLEM.

THIS AFTERNOON I ENTERED THE HIGHWAY AND WAS GOING ABOUT 60-65 MPH WHEN MY CAR SUDDENLY STARTED ACCELERATING ON ITS OWN, I REPEATEDLY DEPRESSED THE BRAKE, EVEN STANDING ON IT IN AN ATTEMPT TO SLOW THE CAR. THE CAR WAS MAKING A REVVING SOUND AND THE BRAKES WERE DOING NOTHING TO SLOW THE CAR, IT JUST KEPT ACCELERATING. FINALLY, THE BRAKES SEEMED TO ENGAGE, THE REVVING STOPPED, AND THE CAR SEEMED NORMAL AGAIN. I PULLED OFF THE HIGHWAY AND CALLED AAA TO HAVE THE CAR TOWED TO MECHANIC. CAR HAS ABOUT 105,000 MILES ON IT AND IT'S BEEN VERY RELIABLE UP UNTIL NOW. I WILL REPORT TO TOYOTA AND I WILL NOT DRIVE THIS CAR AGAIN, MUCH LESS LET MY CHILDREN RIDE IN IT.

I WAS DRIVING MY TOYOTA SIENNA 2006 TODAY MORNING AND THE DRIVER IN FRONT OF ME ABRUPTLY STOPPED. I WAS MAINTAINING A SAFE DISTANCE AND IMMEDIATELY HIT MY BRAKES. ALTHOUGH THE BRAKES SEEMED TO ENGAGE, THE CAR ACCELERATED AND VERY BADLY REAR-ENDED THE CAR IN FRONT ME. HAS THIS HAPPENED TO ANYONE BEFORE WITH THE CAR AUTO-ACCELERATING ON IT'S OWN? *TR

ON AUGUST 1ST AT APPROXIMATELY 10:11PM [144298 MILES ON THE VEHICLE] AT THE I-10EAST TO I-75SOUTH INTERCHANGE AFTER MERGING ONTO I-75 SOUTH. TRAVELING ON I-10 EAST FROM TALLAHASSEE TO ORLANDO USING THE CRUISE CONTROL WHICH WAS SET AT 75MPH ACCORDING TO THE SPEEDOMETER - IN ORDER TO TAKE THE I-75 SOUTHBOUND (TAMPA-ORLANDO) EXIT I APPLIED THE BRAKE TO SLOW DOWN AND RELEASE THE CRUISE CONTROL. UPON MERGING ONTO I-75 FROM THE RAMP I WAS TRAVELING AT ABOUT 55 TO 60 MPH AND WENT TO SELECT RESUME ON THE CRUISE CONTROL. I REMOVED MY FOOT FROM THE ACCELERATOR AS I ALWAYS DO AND LET THE CRUISE DO THE WORK. THE VEHICLE ACCELERATED AS EXPECTED TO 75 MPH - THE SET POINT AND STAYED THERE FOR ABOUT 2 SECONDS (LONG ENOUGH FOR ME TO NOTICE THE SPEEDOMETER PAUSE AT 75MPH AND THEN THE VEHICLE ACCELERATED FAST AND HARD AGAIN (LIKE FULL THROTTLE) AND KEPT GOING IN ABOUT 2 SECONDS I WAS NOW AT 85 AND STILL ACCELERATING; I APPLIED MY BRAKES TO RELEASE THE CRUISE CONTROL AND SLOW THE VEHICLE - IT RELEASED THE CRUISE AND I WAS ABLE TO SLOW DOWN - I DID NOT USE THE CRUISE CONTROL AFTER THAT. *TR

TL* THE CONTACT OWNS A 2006 TOYOTA SIENNA. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 65 MPH, THE VEHICLE UNEXPECTEDLY INCREASED ACCELERATION. THE VEHICLE FAILED TO SLOW DOWN UPON DEPRESSING THE BRAKE. AFTER REAPPLYING THE BRAKE PEDAL AND ENGAGING THE EMERGENCY BRAKE THE SPEED RATE BEGAN TO REDUCE TO 50 MPH. THE VEHICLE WAS THEN MANEUVERED TO THE SIDE ROAD WHERE THE GEAR LEVER WAS SHIFTED INTO PARK. THE VEHICLE CAME TO A COMPLETE STOP AND WAS TOWED TO AN INDEPENDENT MECHANIC. THE VEHICLE WAS IN THE PROCESS OF BEING DIAGNOSED. THE MANUFACTURER WAS NOTIFIED AND THEY RECOMMENDED THE VEHICLE BE INSPECTED BY THE DEALER. THE APPROXIMATE FAILURE MILEAGE WAS 111,000.

APPROACHING SLIGHT RIGHT TURN ON A PARK WAY AT ABOUT 40MPH,DOWN HILL OF THE RIGHT TURN SUDDENLY THE SLIP ICON LIGHT ON THE DASH BOARD WAS ON AND OFF WITH BEEPING SOUND ALARM AND OBSERVED GRINDING OR BRAKING SOUND ON THE VEHICLE WHICH MADE JERKING LIKE ON AND OFF POWER OF THE VEHICLE. ROAD CONDITION WAS DRY AND SUNNY AT ABOUT 11:30 AM. *TR

TL* THE CONTACT OWNS 2006 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE MERGING ONTO THE HIGHWAY AT 65 MPH, THE VEHICLE ABNORMALLY ACCELERATED TO 100 MPH. THE ACCELERATOR PEDAL HAD BECOME STUCK AND WOULD NOT RELEASE. THE CONTACT HAD TO REACH DOWN UNDER THE STEERING WHEEL AND RELEASE THE LODGED ACCELERATOR PEDAL, WHILE CONTINUING TO MANEUVER THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHO INSPECTED THE VEHICLE FOR TEN DAYS BUT WAS UNABLE TO DIAGNOSE A FAILURE. THE MANUFACTURER WAS THEN NOTIFIED AND A COMPLAINT WAS FILED. THE MANUFACTURER SENT AN INVESTIGATOR TO FURTHER INSPECT THE FAILURE HOWEVER, WAS UNABLE TO DETERMINE A FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 80,000.

COMING UP TO AN INTERSECTION, CAR KEPT ACCELERATING AS I LIFTED MY FOOT OFF OF THE GAS PEDAL, HAD TO PUSH HARD ON THE BRAKE AS ENGINE CONTINUED TO REV, PLACED IN NEUTRAL, DEPRESSED GAS PEDAL A COUPLE MORE TIMES, ENGINE QUIT REVVING. DISCOVERED THAT ANCHORS FOR THE DRIVER'S SIDE FLOOR MAT HAD COME OUT OF THE CARPET AND ALLOWED THE FLOOR MAT TO CREEP UP AFFECTING THE GAS PEDAL. REMOVED THE MAT, TOOK TO LOCAL TOYOTA DEALER WHO SAID THERE WAS NO RECALL REGARDING THE SIENNA FLOOR MATS, THE DEALER REPLACED THE 2 RINGS IN THE CARPET USED TO ANCHOR AT MY COST, ONE ANCHOR BECAME DISLODGED AGAIN WITHIN A DAY. SEEMS THAT THERE IS SOME TYPE OF DEFECT IN THE ENGINEERING OF THAT RING USED TO SANDWICH/SECURE INTO THE CARPET. *TR

I WAS ATTEMPTING TO PARK MY 2006 TOYOTA SIENNA WHEN SUDDENLY THE ENGINE STARTED TO REV LOUDLY & THE CAR CONTINUED TO MOVE FORWARD, EVEN AS I FRANTICALLY APPLIED THE BRAKES. THE CAR WOULD NOT STOP BUT MY FAST-THINKING HUSBAND QUICKLY PUT THE CAR INTO NEUTRAL & THEN SHUT THE CAR OFF. WE DROVE TO OUR TOYOTA DEALER IN VINELAND, NJ, WHERE THEY PERFORMED DIAGNOSTIC TESTS BUT COULDN'T FIND ANYTHING WRONG. THEIR DETERMINATION WAS THAT IT MUST HAVE BEEN THE FLOOR MAT PRESSING ON THE ACCELERATOR. I AM SURE THAT THE MAT WAS NOT THE PROBLEM AND THAT TOYOTA IS ATTEMPTING TO COVER UP A PROBLEM WITH A CAR THAT IS NOT ALREADY ON THEIR RECALL LIST. *TR

2006 TOYOTA SIENNA CONCERN *GR THE CONSUMER STATED THE VEHICLE SEEMED TO TRAVEL EXTREMELY FAST EVEN THOUGH SHE WAS DRIVING BETWEEN 60-65 MPH.

WHEN STARTING TO ACCELERATE FROM A STOP AT A LIGHT, MY TOYOTA SIENNA SUDDENLY BOLTED FORWARD AS IF A BOULDER HAD BEEN DROPPED ON THE ACCELERATOR. I BRAKED AS HARD AS I COULD, BUT WAS ONLY ABLE TO KEEP THE SPEED DOWN TO ABOUT 40-45 MPH. EVENTUALLY, IT EITHER IT LET UP ON ITS OWN, OR I SHIFTED INTO NEUTRAL AND SLOWED, I AM NOT SURE WHICH -- IT HAPPENED SO FAST. I IMMEDIATELY GOT OUT OF MY CAR AND LOOKED TO SEE IF ANYTHING WAS ON THE ACCELERATOR, BUT THERE WAS NOTHING. I DO HAVE FLOOR MATS, BUT THEY ARE CUT TO AVOID THE PEDALS AND IN FACT WERE NOT CAUGHT ON THE PEDALS. THIS IS THE ONE AND ONLY TIME IT HAS HAPPENED. I REPORTED IT TO TOYOTA BUT THEY INFORMED ME THAT SIENNAS DO NOT HAVE THE PART THAT IS CAUSING THE SUDDEN ACCELERATION PROBLEM. *TR

I WAS GOING DOWN AN OFF RAMP IN MY SIENNA, BRAKING GRADUALLY AS I CAME TO THE BOTTOM OF THE RAMP. THERE WAS ANOTHER CAR STOPPED ABOUT 6 FT AHEAD OF ME. I STILL HAD MY FOOT ON THE BRAKE WHEN THE ENGINE SURGED AND THE VAN LURCHED FORWARD. I STOMPED DOWN ON THE BRAKE AND THE VAN DID STOP BEFORE IT HIT THE CAR IN FRONT OF ME. I HAVE TAKEN THE VAN INTO THE LOCAL DEALER (TOYOTA OF KNOXVILLE) BUT THEY COULD FIND NO PROBLEMS. I HAVE ALSO REPORTED THE INCIDENT TO THE TOYOTA CONSUMER HOTLINE. *TR

THE ACCIDENT HAPPENED 3/9/2010. THE ACCIDENT INVOLVES OUR 2006 TOYOTA SIENNA... THERE WERE TWO ADULTS AND THREE SMALL CHILDREN IN THE VAN. MY HUSBAND, WHO WAS DRIVING, SLOWED DOWN TO MAKE A RIGHT HAND TURN INTO A GAS STATION. WHILE HE WAS TURNING... THE VAN ACCELERATED AT A HIGH SPEED... MY HUSBAND TRIED TO APPLY BRAKES TO NO AVAIL. WE SMASHED INTO A PARKED CAR (WITH OWNER STANDING NEXT TO IT PUMPING GAS) AT THE GAS STATION PUMP AND THEN THE VAN CONTINUED TO GO A BIT BEFORE SLOWING DOWN AT A SNOW BERM. LUCKILY NO ONE WAS BADLY INJURED. *TR

2006 TOYOTA SIENNA LE WITH BZ PACKAGE (VSA) - SAFETY ISSUE (ELECTRONICS): VEHICLE STABILITY CONTROL SYSTEM (VSA) IS UNSAFE DURING ROAD SLIPPERY CONDITIONS IF CRUISE CONTROL IS USED. THE SLIPPERY CONDITION COULD BE RAINY DAY OR SNOWING OR ICY ROAD CONDITIONS. THE INCIDENT OCCURRED SEVERAL TIME. THE FIRST TIME I NOTICED THE ISSUE IS AROUND SEPTEMBER OF 2008. IT WAS HEAVY RAIN, I WAS DRIVING ON A HIGHWAY WITH NORMAL SPEED. THE VAN WAS SET TO CRUISE AT 65 MPH. I RAN OVER A SMALL POT OF WATER ON THE ROAD. ONE OF THE TIRE PROBABLY SLIPPED FOR A BRIEF MILLI-SECOND. THE VSA CONTROL KICKED IN (I CAN SEE THE VSA LIGHT FLASHES), THE VAN WAS THEN RUNNING FROM SIDE TO SIDE AND THE RPM SUDDENLY JUMP UP (VIOLENTLY). THE VAN WAS DIFFICULT TO CONTROL. I TAP THE BRAKE TO DISENGAGE THE CRUISE CONTROL. THEN THE VAN WENT BACK TO NORMAL. 2ND INCIDENT, ABOUT DECEMBER OF 2008, I WAS DRIVING ON THE HIGHWAY WITH LIGHT SNOW. THE VAN WAS CRUISING AT 55 MPH. THE VAN PASSED A SLIPPERY SPOT. THE VSA KICKED IN AND CAUSED VIOLENT LEFT AND RIGHT MOVEMENT OF THE VAN AS WELL AS SUDDEN ACCELERATION. THE INCIDENT ALMOST CAUSED AN ACCIDENT. SINCE THEN, I STOPPED USING CRUISE CONTROL ON THE RAINY OR SNOWY DAYS. BUT IF ANYONE OUT THERE WITH TOYOTA MINIVAN, I WOULD LIKE THEM TO KNOW IT IS A SERIOUS POTENTIAL PROBLEM. I TOOK MY VAN TO BE CHECKED OUT AT THE TOYOTA DEALERSHIP. THEY SAID COULD NOT FIND THE PROBLEM AND IT IS NORMAL AS IS. *TR

WHEN USING CRUISE CONTROL OUR TOYOTA SIENNA 2006 VAN WILL INCREASE IN SPEED WITHOUT ANY CHANGES. WE HAVE STOP USING CRUISE CONTROL TO PREVENT ANY INCREASE IN SPEED. *TR

1. CRUISE CONTROL DEVICE ON MY 1996 TOYOTA SIENNA HAS BEEN BEHAVING ERRATICALLY SINCE ABOUT 2 MONTHS. IT HAS OVER 45000 MILES ON THE ODOMETER AND IS THUS OUT OF WARRANTY. 2. MECHANICALLY THERE DOES NOT APPEAR TO BE ANY DEFECT. HOWEVER THE FOLLOWING ANOMALIES ARE BEING OBSERVED DURING THE PAST 2 MONTHS. A: 90% OF THE TIME IN SPEEDS IN EXCESS OF 50 MPH, WHEN I TRY TO SET THE CRUISING SPEED BY PRESSING THE CCL (CRUISE CONTROL LEVER) DOWNWARDS, NOTHING HAPPENS. IN MORE THAN 50% OF THESE TIMES, IF I LIFT THE CCL UPWARDS (NORMALLY THE METHOD TO RE-SET CRUISING SPEED AFTER BRAKING/SLOWING DOWN) THE CRUISING SPEED GETS SET. B. UNDER CONDITIONS AS IN 'A' ABOVE MANY OF THE OPERATIONS OF THE CCL APPEARS TO HAPPEN IN AN INVERTED MANNER, LIKE SETTING INSTEAD OF RE-SETTING, RE-SETTING INSTEAD OF SETTING, ETC. 3. IT APPEARS THERE IS SOMETHING DEFINITELY WRONG WITH THE ELECTRONICS OF THE CRUISE CONTROL SYSTEM, AND WHILE THIS HAS NOT HAPPENED SO FAR, MAY IN FACT, CAUSE UNWARRANTED DE-CELERATION/ACCELERATION, AND COULD CAUSE ACCIDENTS. 4. IT IS EMPHASIZED THAT THESE ANOMALIES HAVE *** NOT *** CAUSED ANY ACCIDENT YET. THIS VEHICLE IS *** NOT *** INCLUDED IN ANY UNEXPECTED ACCELERATION-RELATED RECALLS. BUT THIS BEHAVIOR OF THE CRUISE CONTROL MAY HAVE SOMETHING TO DO WITH UNUSUAL ACCELERATIONS. *TR

MY 2006 TOYOTA SIENNA IS MAKING THIS UNINTENDED ACCELERATION EVEN AFTER I MAKE A COMPLETE TURN, OR DRIVING IN A SCHOOL ZONE. THIS IS STARTING TO GET ME WORRIED SINCE I AM USING THIS TO TRANSPORT MY 5-YEAR OLD DAUGHTER. *TR

I AM ASSUMING YOU HAVE SEEN THE ARTICLE ABOUT STEVE WOZNIAK COMPLAINING ABOUT HIS CRUISE CONTROL ON HIS TOYOTA PRIUS. IT IS AN ISSUE OF USING CRUISE CONTROL WITH THE SONAR ACTIVATED TO SLOW THE CAR DOWN TO MAINTAIN A SAFE DISTANCE BETWEEN THE CAR IN FRONT OF YOU. WHEN THE CAR IN FRONT MOVED OUT OF YOUR LANE, YOUR CAR TAKES OFF LIKE A ROCKET TO REGAIN THE PROGRAMMED SPEED. I HAVE A TOYOTA SIENNA MINI VAN THAT DOES THE SAME THING HE DESCRIBED. WHEN I COMPLAIN TO THE DEALER THEY TELL ME IT WORKS AS DESIGNED. I ASK THEM IF THEY WANT TO DRIVE THEIR KIDS AROUND ON THE INTERSTATES USING THE CRUISE CONTROL WITH THE SONAR ACTIVATED OR PAY MY SPEEDING TICKET WHEN I GET PULLED OVER WHEN IT DOES THIS. AFTER ACCELERATING AT SUCH A HIGH SPEED THE BRAKING MECHANISM KICKS IN TO SLOW THE CAR DOWN. SO YOU KNOW YOU HAVE GONE ABOVE THE SPEED YOU SET THE CRUISE CONTROL. A CAR SHOULDN'T TAKE OFF LIKE A ROCKET AND CAUSE YOU TO SPEED WHEN THE CAR IN FRONT OF YOU MOVES OUT OF YOUR LANE. IT ALSO DOES THIS WITH THE SONAR OFF AND HITTING THE "RESUME SPEED" SWITCH ON THE CRUISE. I HAVE NOT HAD AN ACCIDENT WITH THIS ISSUE, BUT IT SURE IS SCARY WHEN IT DOES THIS. AS A RESULT, I DON'T USE MY CRUISE CONTROL VERY OFTEN AND IF I DO, USUALLY KICK IT OFF BY TAPPING THE BRAKE WHEN THE SONAR SLOWS THE CAR DOWN SO IT DOESN'T TAKE OFF LIKE A ROCKET. I AM SURE IT IS A PROGRAMMING ISSUE BUT IT SURE ISN'T SAFE OR COMFORTING THE WAY IT CURRENTLY WORKS. *TR

TWO EPISODES OF SUDDEN UNEXPLAINABLE ACCELERATION. 2006 TOYOTA SIENNA MINI-VAN. FIRST INCIDENT: DRIVING AT ABOUT 25 OR 30 MPH. CAR SUDDENLY SPED UP. USING BRAKE STOPPED THE CAR. SECOND INCIDENT OCCURRED WHEN I PUT CAR IN REVERSE TO BACK INTO MY DRIVEWAY; SUDDEN SPEED INCREASE IN REVERSE. BRAKE WORKED TO STOP. *TR

I WAS TRAVELING ALONE ON ERRANDS AND HAD STOPPED AT A T-INTERSECTION, POSITIONED AT THE TOP OF THE "T" AND PREPARING TO TURN RIGHT. I'D LET AFEW CARS GO PAST, TRAVELING ON THE MAIN STREET WITH TRAFFIC CLOSEST TO ME GOING FROM LEFT TO RIGHT. WHEN THOSE CARS HAD PASSED AND IT WAS SAFE TO TURN RIGHT ONTO THE MAIN STREET, I STARTED TO SLOWLY DEPRESS THE GAS PEDAL TO ACCELERATE. SUDDENLY THE CAR BOLTED FORWARD AND OUT OF CONTROL, ACCELERATING DIRECTLY ACROSS THE STREET AND INTO THE PATH OF ONCOMING TRAFFIC TRAVELING RIGHT TO LEFT. A CAR GOING ABOUT 40 MPH SLAMMED INTO THE RIGHT FRONT PASSENGER SIDE OF MY CAR. THE AIRBAGS DEPLOYED AND BOTH OUR CARS CAME TO A COMPLETE STOP. I WAS DAZED FROM THE COLLISION AND EXITED MY CAR FROM THE DRIVER'S SIDE AS SOON AS POSSIBLE. I COULD SEE THAT THE WHOLE FRONT OF MY CAR, INCLUDING THE ENGINE WAS COMPLETELY DEMOLISHED. I WAS IN SHOCK AND A LADY FROM A NEARBY HOUSE WHO HAD HEARD THE CRASH CAME OUT WITH A CHAIR FOR ME TO SIT ME DOWN ON WHILE THE POLICE AND PARAMEDICS WERE ON THE WAY. I NEVER WENT TO THE PASSENGER SIDE OF THE CAR AND DON'T KNOW THE CONDITION OF THE OTHER DRIVER OR THEIR CAR. I WAS TAKEN TO THE EMERGENCY ROOM AND SUFFERED CHEST, NECK AND BACK PAIN. I AM QUITE SURE IT WAS THE GAS PEDAL STICKING THAT CAUSED THE CAR TO ACCELERATE SO UNEXPECTEDLY AND QUICKLY, PROPELLING ME THROUGH THE CROSS-TRAFFIC AND ONTO THE OTHER SIDE OF THE STREET. IT WAS AN ABSOLUTELY HORRIBLE ACCIDENT AND I AM STILL IN SHOCK OVER IT, NOT TO MENTION NOT KNOWING THE CONDITION, EXTENT OF INJURIES OR EVEN THE IDENTITY OF THE OTHER DRIVER AS YET. *TR

MY WIFE WAS DRIVING ON A SINGLE LANE SUBURBAN ROAD GOING APPROXIMATELY 45 MPH. SHE TRIED TO SLOW DOWN USING THE BRAKES, BUT THE CAR WOULDN'T SLOW DOWN. SHE TRIED THE BRAKE A SECOND TIME, BUT THE CAR DIDN'T SLOW DOWN. SINCE THERE WERE VEHICLES IN FRONT OF HER, SHE WENT OFF THE ROAD (FORTUNATELY BY AN OPEN FIELD) AND SIDE SWIPED A POLE AND WENT DOWN INTO A SMALL RAVINE. THE ENTIRE DRIVERS SIDE OF THE CAR WAS DAMAGED...OVER $12,000. THE LOCAL TOYOTA DEALER ASSURED US THAT THE BRAKES WERE FINE. TOYOTA (PARENT COMPANY) WAS NOT MUCH HELP. WITH ALL THE RECENT MEDIA ATTENTION WITH THE STUCK ACCELERATORS, I ASKED THE DEALER TO CHECK FOR THAT AS WELL....THEY SAID THE CAR IS FINE. *CN

WE BOUGHT A 2006 TOYOTA SIENNA VAN BRAND NEW FROM A LOCAL DEALER. ALMOST FROM THE BEGINNING THE RPMS WOULD INCREASE WITHOUT PROVOCATION. I INITIALLY THOUGHT IT WAS A PROBLEM WITH THE TRANSMISSION AND HAD IT CHECKED BUT IT TURNED OUT OKAY. I THEN THOUGHT IT WAS MAYBE A PROBLEM WITH THE FUEL LINE SO I HAD IT FLUSHED BUT THE PROBLEM PERSISTS. IT HAPPENS OFF AND ON AND USUALLY WHEN I AM DRIVING ALONG. BECAUSE I HAVE OWNED TOYOTA'S BEFORE AND NEVER HAD A PROBLEM AND THE DEALER AND THE LOCAL SHOP SAID EVERYTHING WAS OKAY I WASN'T WORRIED UNTIL THE RECALL WHICH DESCRIBES EXACTLY THE PROBLEM I HAVE BEEN EXPERIENCING. THE PROBLEM IS RECURRENT - PLEASE ADVISE. *TR

TL* THE CONTACT OWNS A 2006 TOYOTA SIENNA. WHENEVER THE CONTACT DRIVES THE VEHICLE AT ANY SPEED SHE NOTICED THAT THE ACCELERATOR PEDAL IS DEPRESSING ON ITS OWN CAUSING THE VEHICLE TO SLIGHTLY JERK FORWARD. THE VEHICLE WAS TAKEN TO THE DEALERSHIP WHERE THE CONTACT WAS INFORMED THAT THERE WAS A CALIBRATION ISSUE. THERE WERE NO PRIOR WARNINGS AND THE CURRENT AND FAILURE MILEAGES WERE 30000.

I WAS DRIVING MY 2006 TOYOTA SIENNA LE THROUGH A PARKING GARAGE. AS I WAS MAKING A SHARP RIGHT-HAND TURN INTO MY PARKING SPOT, THE VEHICLE ACCELERATED AT FULL-THROTTLE AND SMASHED INTO A CONCRETE WALL. THE FRONT BUMPER WAS HEAVILY DAMAGED AND I HAD SOME SYMPTOMS OF WHIPLASH FOR A FEW DAYS. IT HASN'T HAPPENED SINCE THEN, THANKFULLY. I MENTIONED THE INCIDENT TO THE TOYOTA SERVICE REP AT MY NEXT SCHEDULED MAINTENANCE, BUT THERE WAS NO INSPECTION MADE. *TR

TL*THE CONTACT OWNS A 2006 TOYOTA SIENNA. WHILE DRIVING 40 MPH AND REMOVING HER FOOT OFF OF THE ACCELERATOR PEDAL IT BECAME STUCK AS IT WAS RELEASED. SHE HAD TO PUMP THE BRAKES SO THAT THE VEHICLE COULD SLOW DOWN. THE DEALER WAS CONTACTED AND STATED THAT THEY WERE UNAWARE OF ANY RELATED FAILURES. THERE WERE NO REPAIRS MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 12 AND THE CURRENT MILEAGE WAS 42,484. UPDATED 03/10/10. *LJ UPDATED 06/04/10

MY 2006 TOYOTA SIENNA'S ACCELERATOR GETS STUCK IN THE ACCELERATION POSITION. I WAS ENTERING THE HIGHWAY SO I WAS QUICKLY ACCELERATING TO MERGE WITH TRAFFIC AND ONCE I MERGED WITH TRAFFIC I RELEASED THE ACCELERATOR PEDAL TO ADJUST MY SPEED AND THE PEDAL REMAINED IN ACCELERATION MODE AND I WAS UNABLE TO STOP IT. I TRIED PRESSING THE BRAKE PEDAL TO STOP OR DECREASE THE ACCELERATION AND THAT DIDN'T WORK. I TRIED DEPRESSING THE ACCELERATOR PEDAL AGAIN TO SEE IF IT WAS STUCK AND THAT DIDN'T WORK. EVENTUALLY THE ACCELERATION STOPPED ON ITS OWN. THIS HAS HAPPENED TO ME TWICE AND MY HUSBAND ONCE. SO FAR THIS HAS OCCURRED THREE TIMES SINCE WE'VE HAD THE VEHICLE. I TOOK IT INTO A TOYOTA DEALER WHERE THEY RECORDED MY ISSUE ON THE SERVICE INVOICE ON 2/17/07 AND WERE UNABLE TO DUPLICATE THE ISSUE AND REMARKED THAT MY FLOOR MATS WERE UPSIDE DOWN AND THAT I SHOULD INSTALL THEM PROPERLY. *TR

FAILURE OF THE ADAPTIVE CRUISE CONTROL MODULE ON A 2006 TOYOTA SIENNA XLE LIMITED. THE ADAPTIVE CRUISE CONTROL MODULE, LOCATED UNDER THE FRONT BUMPER ON THE PASSENGER SIDE, FAILS COMPLETELY AND CONTINUOUSLY RESULTING IN COMPLETE FAILURE OF THE CRUISE CONTROL SYSTEM. THE MODULE IS NOT SEALED PROPERLY THEREBY ALLOWING MOISTURE INSIDE RESULTING IN CORROSION AND FAILURE OF THE PART. WHEN ACTUATED, THE PART IS DESIGNED TO AUTOMATICALLY SLOW THE VEHICLE WHILE APPROACHING SLOWER TRAFFIC FROM BEHIND. FAILURE OF THIS PART WHILE DRIVING COULD RESULT IN AN ACCIDENT IF THE MODULE DOES NOT AUTOMATICALLY SLOW THE VEHICLE PROPERLY. THE VEHICLE IN QUESTION HAS ONLY 21,000 MILES ON IT. THE FAILURE OCCURRED AT APPROXIMATELY 15,000 MILES. TOYOTA OF COLORADO SPRINGS REPLACED THE PART AT COST TO THE OWNER OF THE VEHICLE. *TR

WE HAVE A TOYOTA 2006 THAT WILL INCREASE SURGES IN ENGINE SPEED WHEN STOOPED WHICH HAS ALL MOST CAUSED THREE ACCIDENTS ONE GOING INTO A BUILDING, ALSO THE VEHICLE HESITATES WHEN THE ACCELERATOR IS PRESSED ON START. WHEN SITTING IN TRAFFIC YOU HAVE TO HOLD YOUR FOOT ON THE BRAKE BECAUSE YOU WILL GET AN ENGINE SURGE WHICH RUNS THE RPM'S UP TO 5,000 THEN IT DROPS OFF. IT IS VERY DANGEROUSLY BECAUSE YOU DON'T KNOW WHEN IT WILL HAPPEN AND CONTROLLING THE VAN IS VERY UNPREDICTABLE. *TR

I OWN A TOYOTA SIENNA 2006 MODEL. WHEN IN TRAFFIC THE CAR SOMETIMES HESITATES WHEN THE ACCELATOR IS PRESSED AND AT OTHER TIMES IT SURGES FORWARD DANGEROUSLY. THEREFORE CONTROLLING THE CAR IS UNPREDICTIBLE. THE EXACT RESPONSE IS ALSO NOTICABLE AT A TRAFFICE LIGHT OR A STOP SIGN. THE FAILURE HAPPENS OFTEN. *TR

SIENNA UNCONTROLLED ACCELERATION!! IT HAPPENED TO OUR 2006 SIENNA YESTERDAY 2/21/2007 - -MY WIFE WAS ABOUT TO STOP THE CAR WHILE PARKING IT AT A PARKING SPACE, SUDDENLY IT ACCELERATED (VERY FAST!) AND KNOCKED DOWN A TREE AND SCRATCHED A COUPLE OF PARKED CARS. IT TOOK A TREE, SOME BUSHES AND A DOUBLE RAISED CURBS TO STOP THE VAN. THE BUMPER WAS DAMAGED (BY THE TREE) AND THE RIGHT SIDE OF VAN DENTED. MY WIFE IS A CAREFUL DRIVER (AND WITH OUR TWO TODDLERS INSIDE!) AND SHE IS VERY SURE SHE DID NOTHING WRONG. WE ARE VERY CONCERNED TO DRIVE IT AGAIN IF THE REPAIR SHOP CANNOT FIND DEFECT WITH THE VAN. I HAVE A SIMILAR ACCIDENT REPORT HERE: HTTP://TOWNHALL-TALK.EDMUNDS.COM/WEBX?14@@.F105086/0 *JB
