“Bought a new 2019 Prius from grossinger Toyota on 9/13, went back to the dealer on 9/16 to get my old city sticker from my old car (this new car only had 61 miles), the new car broke while I was there. The entire dashboard went off (blinders cannot be turn on. No indication of speed, no indication of vehicle level, etc). Anything that's on the dashboard went blank.

“* I was pulling into a parking space at a slow speed. When I applied the brake the car accelerated causing the car to scrape the car next to the space. The car then stopped. * The acceleration was out of my control and the brakes did not stop it. Fortunately there was no person in front of me. * The Tow truck operator who came to get the car experienced the same issue when pulling into the bay at the dealer. I do not know about the manufacturer during their inspection as they did not provide me with that information. …”
