What 2017 Toyota Sienna owners say
Most recent owner complaints, unedited.
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 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.
