I am submitting this complaint to report a safety concern involving Tesla’s full self-driving (fsd) system. On [xxx], while my vehicle was operating under fsd in las vegas nv, the vehicle was positioned in a clearly marked left-turn-only lane. The roadway had visible pavement arrows indicating a required left turn. Despite these clear lane-direction markings, the fsd system proceeded straight instead of turning left. The maneuver occurred abruptly. I did not receive a clear or timely takeover warning prior to the deviation. The transition from a left-turn lane into a straight path happened quickly, leaving extremely limited reaction time (estimated less than one second). As a result of the system’s unexpected behavior, a collision occurred with another vehicle traveling straight. At the time of the incident: weather conditions were clear. Road markings were visible. There were no obstructions blocking lane markings. I was attentive and looking at the road. The police report assigned fault to me as the driver; however, the vehicle was actively operating under Tesla’s fsd system when it disregarded the clearly marked left-turn-only lane. I am concerned that this behavior represents a potential safety defect involving: lane interpretation errors failure to follow traffic control markings insufficient takeover warning timing if this issue is systemic, it may pose a broader safety risk to other road users. I respectfully request that NHTSA review this matter as a potential safety defect related to Tesla’s full self-driving system.
