NHTSA complaint #11701831

Owner complaint summary

Component/system that failed: Tesla Full Self-Driving (Supervised) software version 14.x (2025.38.x and later). The issue is software-only and remains installed on any vehicle updated to v14. Description of safety defect: FSD v14 deliberately removes the driver’s ability to set or adjust maximum speed offset using the right scroll wheel (feature present in all prior versions including my current v13.2.9). As a result, the system routinely exceeds posted speed limits by 5–20 mph with no way for the supervised driver to correct it short of fully disengaging FSD. The vehicle ignores speed-limit signs, relies on inaccurate map data, and follows surrounding traffic speed instead of the legal limit, even in school zones, construction zones, residential areas, and adverse weather. This significantly increases risk of collision, injury, and traffic citations. Reproduced/confirmed: Widely reproduced by thousands of owners on Tesla forums, Reddit, and X immediately after v14 rollout in late 2025. I have chosen to remain on v13.2.9 to avoid this exact defect. Inspected by manufacturer or others: No in-person inspection required; Tesla has full remote log access. Multiple owners have submitted in-car bug reports. Warning lamps/messages: None. The speed-offset control is simply grayed out and non-functional by design in v14. Vehicle available for inspection upon request.
