Example complaints

“A sticky accelerator caused my 2021 Prius to lurch forward into a wall. I was pulling into a parking place when this happened. The front airbag deployed. This is the second time this has happened to me with a Prius. In my previous Prius it happened to me two years ago. Both times the vehicle suddenly lurched forward. It was terrifying.”
