• “While my wife was pulling into park the car and pressing the brake, the car all of a sudden accelerated into the building. Pressing the brake failed to stop the car. No person was in the way of the car so no one other than my wife was at risk of injury. The problem has not been reproduced since the car was totaled. The car was inspected by the insurance for loss but that was it. Police and manufacturer have not inspected the car. No warnings were presented prior to the accident.”
