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.

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHILE DRIVING ABOVE 55 MPH ON AN INCLINING OR DESCENDING SURFACE, THE STABILITY CONTROL WOULD SUDDENLY ACTIVATE AND THE SPEED WOULD SUDDENLY DECREASE. THERE WAS NO RESPONSE WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. THE CONTACT INDICATED THAT THE FAILURE ALSO FREQUENTLY OCCURRED WHEN SWITCHING LANES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO WAS UNABLE TO DETERMINE THE CAUSE OF THE FAILURES. THE MANUFACTURER AND LOCAL DEALER WERE NOT NOTIFIED. THE FAILURE MILEAGE WAS 130,000.

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...

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

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. PLANNED TO HAVE CHECKED BUT DEC.1 2012 AT THE TANGER OUTLET MALL IN CANONSBURG PA. 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. ALL OF A SUDDEN THE VEHICLE FLEW BACKWARD SO FAST THAT BEFORE WE COULD YELL STOP MY VEHICLE HAD SLAMMED INTO THE SUV PARKED ACROSS THE AISLE SO HARD THAT IT PUSHED THE SUV INTO THE CAR PARKED IN FRONT OF IT IN THE NEXT ROW. 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

THERE IS AN INTERMITTENT LAG IN THROTTLE RESPONSE AFTER PRESSING ON THE ACCELERATION PEDAL FOR APPROXIMATELY 2 SECONDS. DURING THE LAG PERIOD, THE VEHICLE DOES NOT ACCELERATE.

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
