On June 29th, 2023 at approximately 8:45 AM we were pulling into a parking space slowly tapping the brakes to slow and stop the vehicle. About 2/3 of the way into the parking stall around 3 or 4 feet from the curb, the vehicle actually accelerated while pressing the brake jumping the curb. We pressed on the brakes again and the car accelerated even faster crossing the sidewalk crashing into a building. We believe the brakes caused the SUA (Sudden Unintended Acceleration) accelerating the vehicle twice and the vehicle failed to apply the brakes. We believe this would've been caused by a computer error on the vehicle. We also believe the vehicle to initiate the two safety systems failed, Crash Imminent Braking & Dynamic Brake Support thus being able to avoid the accident. To the best of our knowledge, no warnings or alerts were displayed on the vehicle before the crash. We had BMW inspect the vehicle and no defective part was found and the black box indicated the vehicle was accelerating a few seconds before the crash. We do not disagree with this and informed BMW that the car was accelerating on it's own.
