Hi there, I have a new 2009 Toyota Prius. A couple of days ago as I was pulling into the parking spot at the garage my foot on the brake, the car started all of a sudden moving very smoothly without any resistance regardless of my attempts to stop it. It was hitting the wall in front of it a couple of times until I managed to power down the car. The front bumper of the car is completely destroyed and will need to be replaced. I took the car to a dealer to check brakes thoroughly. They did and told me that everything is fine with the brakes. Personally I strongly believe that the brakes have mind of their own and I sincerely hope that they will not fail on me in traffic since I am a mother, I have a 1-year old boy. His safety is a top priority for me. Right after my car was purchased it had to stay at a dealer for a week since there was some electrical problem, I believe with doors. Both that fact and now the brake failure make me wonder if my car is a lemon. Please help to sort this out. Thank you!.
2009 Prius > upon arrival at church, engine would not shut off. Returned home, engine would not shut off. Could not remove 'key' from slot. About 2 hours later, car could be shut off. > called dealer and explained. Dealer said 'this has never happened, we will get back to you' which did not happen. Since then, there have been several times that the power switch had to be pressed several times to make the car shut off. > this is a very dangerous situation in the event of a crash or stuck accelerator. Dot should require manufacturers to use a conventional key switch to allow the driver to shut off the engine.
