The failure mileage was 140,000.”

“shifter broke at 55 mph wouldn't stay in 5 gear, was easily moved to R, N, and flopped around! won't stay in 4 now when used either, or PARK unless held when turning car off. NO warning, shifted down for a hill, speed limit change, and corner in neighborhood as usual, no lights on in car. just happened but upon research, have found many others with this problem online, same veh and same kind of miles.Toyota knows but won't recall their broken plastic piece and no notification to consumer”

“THE SHIFTER LOCKS UP IN PARK AND WON'T COME OUT OF GEAR. IF THE VAN IS RUNNING OR OFF IT WON'T COME OUT OF GEAR. HAVING THE PARKING BRAKE ON MAKES NO DIFFERENCE. HAVE TO ROCK THE VAN BACK AND FORTH TO GET IT OUT OF GEAR.”

“I'VE ONLY HAD THE VAN FOR 5 MONTHS AND THIS PROBLEM HAS OCCURRED OVER A DOZEN TIMES, BEGINNING WITH THE DAY I BOUGHT IT. AND EVERY TIME THIS PROBLEM HAS OCCURRED I'VE BEEN DRIVING ON DRY ROADS. IT USUALLY HAPPENS WHEN DRIVING AROUND A CORNER, ANYWHERE FROM 35-65 MPH, FAR. ALL OF A SUDDEN THE TRACTION CONTROL LIGHT STARTS BEEPING, THE BRAKES ENGAGE ON THEIR OWN, AND THEN ENGINE MAKES A LOUD NOISE (LIKELY DOWNSHIFTING ITSELF). IT'S AS THOUGH THE VEHICLE THINKS IT IS SLIPPING, EVEN THOUGH IT IS NOT, I DRIVE VERY CAUTIOUSLY SO IT'S NOT ME FLYING AROUND A CORNER SUPER FAST, IT ALSO HAPPENS WHEN MY PARTNER DRIVES THE VAN AS WELL. I FINALLY TOOK THE VAN TO A MECHANIC AND THEY TOLD ME IT WAS THE STEERING ANGLE SENSOR THAT WAS FAULTY AND NEEDED TO BE REPLACED, SO I SPENT $900 TO HAVE IT REPLACED. I'VE HAD THE VAN BACK FOR LESS THEN 2 WEEKS AND JUST TRIED TO TAKE IT ON A ROAD TRIP, GOT ABOUT AN HOUR FROM OUR HOUSE AND IT DID IT AGAIN 3 TIMES IN LESS THEN 15 MINUTES, AGAIN DRIVING ON DRY PAVEMENT AND WHEN DRIVING ON A WINDY HIGHWAY. IT'S TERRIFYING WHEN THIS HAPPENS ESPECIALLY BECAUSE IT ALWAYS HAPPENS WHEN WE'RE GOING AROUND A CORNER, IT'S VERY DANGEROUS AND SCARY. IT…”

“THE SHIFT STICK WAS LOOSE AND WOULD MOVE IN ANY DIRECTION. IF THE CAR WAS DRIVING ON D AND SOMEONE WAS TO TAP THE STICK SHIFT SLIGHTLY UP OR DOWN, THE STICK WOULD MOVE EVEN WHEN THE CAR WAS IN MOTION AND BRAKES WERE NOT PRESSED. ANY MAJOR BUMPS WOULD CAUSE THE SHIFT TO MOVE LOOSELY FROM ITS PROPER PLACE AS WELL.”

“MY TOYOTA SIENNA HAS 80,000 MILES AND HAS GEAR HUNTING, WHEN I GO ON A SPEED BUMP IT SURGES AND HESITATES, I DON'T FEEL SAFE AT ALL. I'VE PREVIOUSLY OWNED OTHER TOYOTA'S WITH PROBLEMS NOT LIKE THIS. PLEASE HELP. I LOVE TOYOTA, BUT I VALUE SAFETY.”
