On June 5 2026, my wife drove the vehicle into the garage. While she was exiting the vehicle with the driver's door open, the vehicle unexpectedly continued moving backward. My wife had to move out of the vehicle's path to avoid being struck or potentially crushed. The vehicle continued moving with the driver's door open, and the open door ultimately became lodged against a structural portion of the garage-door opening. Fortunately, my wife escaped physical injury. The vehicle and driver's-door area, however, sustained substantial damage.
