This has happened multiple times. Driving at various speeds. Sometimes driving straight other times turning. ABS activates with out cause. ESC light illuminates. Happens when in traffic causing the van to try to stop in traffic without warning. Thus far mechanic has not been able to duplicate.
At 70000 miles and around 9/1/2023, started to notice our brake stop suddenly steep down pedal when braking at 45mph or higher. Problem starts after fuel pump replacement recall completed by dealership August 2023. Check recall and campaign program, my vehicle VIN specifically not on the recall list for brake booster vacuum pump. I thinks Toyota HQ should take my vehicle into consideration since my vehicle is a 2017 Sienna. Contact HQ they refused to offer to diagnosis nor help replace if applicable. Due to your vin not on the recall, your on your expense.
Parked the car on an incline (our driveway) like we have a 100 times before. Went inside to unload groceries. Came back to the car and from the passenger seat reached over to press the auto-off button. When that was pressed the car started to roll down our driveway with our daughter in the back seat. It rolled across the street, hit the side of our neighbors house, and landed in the woods. My wife sustained major injuries to her arms, legs, hands, and back. She was also 9 months pregnant. Toyota dealership says there's nothing wrong after a 30 minute inspection.
When going down a parking ramp exit, my foot has slipped off the brake 3 time. When looking at the brake pedal it is smaller than most brake pedals. I don't know if anyone else has had this problem, but mandating a minimal size for brake pedal might help
I have a 2017 Toyota Sienna that has needed the braked replaced on average every 6 months and I have already replaced the roaters 4x. This car eats brakes and roaters.
On October 15, 2021 at 2 pm I drove into the driveway of a friend. I turned to the right of the driveway on her grass so I could backup and face the road. I’ve done this many times in the past. On this day as I put my foot on the break the van accelerated at a very very high speed. The van was out of my control at this point. I do not know how fast because this all happened in seconds. I was heading straight to their privacy wood fence only feet away. Approximately 20 feet. I don’t recall breaking again but turned the wheel to the right trying to avoid the fence. I hit the fence at a high speed damaged the left bumper and scraped the drivers side of the door. The next second I attempt to break again so I could back out of this when the van continued to accelerate at high speed going straight toward the house only a few feet away. I attempted to avoid the house and hit the right bumper hard at a high speed on the corner of the house. At this point the acceleration stopped and I was able to backup and turn the car around and finally turn the car off. There is major damage to the van and some to the fence and house. I was very upset and in shock and some soreness the next day but thankfully no one was hurt. This is a very small yard area that this took place at. I am still in shock and extremely confused as to why this happened. I do know without question my foot was not in the accelerator. The van is presently in the body shop. I would like to mention I have a clean record at the age of 64 I have never had an accident and/or speeding ticket in my life. This truly was not human error. I’m a very experienced driver. If it was human error the van should have stopped at the first point of impact on the fence, but did not. It continued to accelerate at a fast speed after hitting the fence hard. The van paused but continued to accelerate at this point when I hit the break again and it went toward the right straight for their house.
The contact owns a 2017 Toyota Sienna. The contact stated while driving 35 MPH and coming to a stop, the brake pedal was depressed but failed to respond. There were no warning lights illuminated. The contact stated the brake pedal was rigid. The contact stated the failure reoccurred while driving. The brake warning light and traction control warning light were illuminated. The vehicle was taken to the dealer who could not determine the cause of the failure. The dealer advised the contact to take the vehicle back to the dealer she purchased the vehicle. The manufacturer was made aware of the failure and referred the contact to the dealer who sold her the vehicle. The vehicle was not repaired. The approximate failure mileage was 14,500.
THE VACUUM BRAKE ASSIST FAILED WITH LESS THAN SLIGHTLY LESS THAN 50K MILES ON THE CAR. NOT SURE EXACTLY WHEN IT FAILED BECAUSE THE BRAKE AND TRACTION CONTROL LIGHTS WERE ON INTERMITTENTLY FOR AWHILE BEFORE WE TOOK THE CAR IN FOR SERVICE. WE DID HAVE A NEAR MISS WHILE MAKING A LONG DRIVE WHEN WE WERE TRYING TO LEAVE THE INTERSTATE ON AN OFF RAMP AND I WAS ALMOST UNABLE TO STOP AT THE TOP OF THE RAMP. I HAD TO ANGLE THE VEHICLE TO THE LEFT TO AVOID HITTING A PICKUP TRUCK AT THE TOP OF THE RAMP.
WHEN I BRAKE (ESPECIALLY FROM HIGHER SPEEDS) THE STEERING WHEEL SHAKES AND THE CAR RIDE FEELS VERY JERKY - ESP FOR THOSE IN THE FRONT SEATS. THERE ALSO SEEMS TO BE A WHINING OR RUBBING NOISE.

OUR 2016 SIENNA WHICH WE PURCHASED LAST MAY ACCELERATED ON IT'S OWN ON 2/16/2017 GOING THROUGH OUR SOUTH OUTSIDE WALL AND MASTER BATHROOM OF OUR HOUSE. MY HUSBAND LEFT THE VAN IN THE DRIVEWAY, UNLOADED THE GROCERIES, THEN GOT BACK INTO THE VAN, STARTED IT, PUT HIS FOOT ON THE BRAKE, SHIFTED TO DRIVE AND WITH HIS FOOT ON THE BRAKE THE VAN ACCELERATED INTO THE THE GARAGE. WE HAVE AN EXTENDED GARAGE WHICH HAD AN OFFICE AREA AND IT PROCEEDED TO PUSH THE OAK DESK THROUGH THE SOUTH EAST OUTSIDE WALL AND MASTER BATH. AS IT CONTINUED TO ACCELERATE AND BURN RUBBER ON OUR FINISHED GARAGE FLOOR, WITH HIS FOOT STILL ON THE BRAKE SLAMMED IT INTO REVERSE. THE SIENNA SHOT OUT OF THE GARAGE, HEADED DOWN OUR DRIVE, INTO OUR LAWN AND OVER OUR WINTER SNOW STAKES. KNOWING IT WAS NOT STOPPING AND THE BRAKES WERE NOT WORKING OTHER THAN LETTING HIM PUT THE CAR INTO GEAR, HE ONCE AGAIN SLAMMED IT INTO DRIVE. THE SIENNA SHOT INTO THE GARAGE A SECOND TIME, HITTING THE S. E. WALL AND YET AGAIN CONTINUED TO BURN RUBBER ON OUR FLOOR AS IT PUSHED THE DESK FURTHER THOUGH THE WALL. ONCE AGAIN, COMPLETELY BESIDE HIMSELF MY HUSBAND SLAMMED IT INTO REVERSE AND WHEN OUTSIDE IT FINALLY STOPPED AFTER HE STOMPED ON THE BREAKS WITH ALL HIS MIGHT! THE AIR BAG DID NOT DEPLOY NOR DID THE BRAKES EVERY BEGIN TO WORK TO SLOW IT DOWN. WE WILL NEVER DRIVE THIS VEHICLE AGAIN AND IT IS BEING STORED AT CARLSON TOYOTA UNTIL WE KNOW WHAT TOYOTA HEADQUARTERS INTENDS TO DO ABOUT THIS PROBLEM. WE ALSO NEED TO KNOW WHAT WE ARE TO DO BEINGS OUR SIENNA WAS PAID FOR AND NOW IT IS WORTHLESS TO US.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
