What 62 owners told NHTSA about the 2023 Toyota Sienna

multiple times this has been an issue. I stepped on the break and the car essentially leaps forward typically when going up down or straight. In November 2024 it happened while going up a hill slowly and I bumped into the vehicle ahead of me. My vehicle had no damage, but the car in front of me had to get a new skid plate and my insurance doubled because of it. Since the incident in November 2024, my car has unintentionally accelerated intermittently. finally, April 2025 this happened my car started shaking jolted forward, engine revving, and then my check engine light came on then immediately contacted my local dealership and scheduled an appointment to get my car in. They have had my vehicle since then and have said it is not safe to give it back to me so I am currently driving a loaner vehicle.

I turned right to park behind another car on the driveway and my car suddenly accelerated hitting the car in front. The collision was strong enough that the car that was hit then hit a barrier at the home.

While driving slowly into a parking slot, the brakes released and the vehicle surged over a parking block and into a sign. On a couple of time previously, I have encountered similar situations but never when parking at slow speed.
