Upon engaging the brake while pulling into a parking spot at our local pizza shop in glenwood springs, CO, our Toyota Sienna accelerated rapidly and hit the brick building 10 feet away. There were no personal injuries but damage to the car and a window in the pizza shop were significant. The car was still going after the crash and if there had not been a brick wall to stop the car I fear what would have happened. The incident was immediately reported to the police and the local Toyota dealer. Though we love the car we are afraid to drive it anymore, nor are we willing to sell it considering what could happen. We need a proper way to dispose of it.
