I attempted to park my vehicle. The brakes did not work they, seemed to have no pressure. The engine then accelerated. I did not press the gasoline pedal. The vehicle moved forward and it struck a wall. Damage to the radar system and front grille of vehicle. I took the vehicle to the dealership and all they did was zip tie a component that came loose from under the steering column and give me a referral to a body shop. As of this time the problem has not been reproduced and the vehicle has not been inspected. The vehicle is available for inspection upon request. No warning lights or other symptoms of the problem prior to the failure.
