Experienced sudden unintended acceleration (SUA) while parking the car. Was pulling into a parking spot at a very slow speed, approx 5 mph and the car accelerated to an extremely high speed on its own without any input from me. Tried to brake to stop the car but the car did not respond or stop or slow down. Due to the SUA event, the car crashed into the side of a building, all air bags in the car were deployed, and the car is a total loss per insurance.
