NHTSA Complaint #11718141 — 2022 TESLA MODEL Y

On December 30th, 2025, my wife experienced a serious and unexpected safety event while using Autosteer in one of our Tesla Model Y cars (we own two of them). The version of the vehicle software in use was v12 (2025.26.8) and the Full Self Driving (Supervised) Software was v12.6.4. The vehicle came to a complete stop at a red traffic light on northbound San Gabriel Blvd in Pasadena at the intersection that controls entry to the I-210 West. After waiting for approximately 55 seconds, Autosteer initiated forward movement into the intersection while the traffic light was still red. The vehicle’s movement was not caused by driver input. My wife’s feet were away from the pedals at the time. There was no visible lead vehicle movement or other obvious external trigger. Fortunately, my wife was attentive and immediately disengaged Autosteer, brought the vehicle to a stop, and carefully reversed back into a safe position. Moments later, multiple fast-moving vehicles crossed the intersection in front of her path. Had she not intervened promptly, there was a realistic risk of a serious side-impact collision. This serious incident was reported to Tesla on 12/30/2025 including a video of the incident. In my correspondence, I requested that all relevant vehicle telemetry, Autosteer/FSD logs, and any uploaded video associated with this time and location be preserved and reviewed. As of today (7 weeks later) they have not followed up with me. The 18-second video was recorded by an independently installed Viofo dashcam, which clearly shows: . the vehicle stopped at a red light, . the light remaining red, . and the vehicle beginning to move forward unexpectedly.
