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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 Toyota Sienna verdict →
