On December 21, at approximately 9:17 PM, my Tesla was operating with Full Self-Driving (Supervised) engaged while reversing out of a parking space at 4 Cook Cir, Medford, MA, USA. During the maneuver, the FSD system failed to detect a low-positioned barrier and collided with it, impacting the rear right quarter panel near the rear right wheel. The damage was caused by the actions of the FSD system while under active control. The vehicle remained drivable; however, the incident represents a failure of the Full Self-Driving system to ensure safe operation during a low-speed maneuver. I believe this incident resulted from a defect or malfunction in the FSD software and request a formal safety investigation.
