Subject: Formal Safety Complaint – Tesla FSD Failure and Missing Video Evidence Vehicle: 2024 Tesla Model Y Long Range VIN: [XXX] FSD Version: FSD (Supervised) v14.3.10 Incident Date: October 9, 2026 Location: [XXX] Dear NHTSA, I am filing a formal safety complaint regarding a suspected failure of Tesla's Full Self-Driving (FSD) system. On XXX, my wife activated FSD while our Tesla Model Y was parked in a parking lot. The vehicle began reversing and collided with another stationary vehicle behind it. Although the other vehicle showed no visible damage, our Tesla suffered significant deformation to its trunk and rear body panels, with estimated repairs of $5,000–$15,000. My primary concern is that FSD apparently failed to detect or respond appropriately to a stationary vehicle directly behind it. Such a failure could have caused serious injuries if a pedestrian or child had been present. Additionally, I requested my vehicle data from Tesla, but the "Video Recording" section was empty. I am concerned about the missing footage and the availability of critical evidence needed to determine what happened. I respectfully request NHTSA to: Investigate the suspected FSD object-detection and reversing safety failure. Request preservation and review of relevant Tesla camera recordings, FSD logs, vehicle telemetry, and collision data, if available. Examine why no video footage was included in my Tesla data download. Determine whether similar incidents indicate a broader public
