“Attempted to park in my garage and overshot the turn. The brake then failed to stop and I dented my garage outer wall. I reversed my car and tried to reposition it to go inside the garage, putting it on drive. However, the brake pedal made the car accelerate and the car went on reverse. It then crashed into the neighbor's garage and crashed the door and car inside. Both the car inside the garage and the garage itself (along with the inside of the house) have been damaged.”
NHTSA complaint #11492215, filed 2022-11“About a year ago and again a few days ago, I was slowly moving my Prius forward when suddenly it accelerated at full speed.

Fortunately, the collision avoidance brakes kicked in and stopped the car just before I hit the fence. In the second case, I was slowly pulling into a parking lot when again the car surged forward. This time I was able to stop the motion with the brakes myself . …”
