NHTSA Complaint #11693723 — 2025 TESLA MODEL 3

On [XXX] at approximately [XXX], I was driving northbound on [XXX] in Phoenix, Arizona in my 2025 Tesla Model 3 using Tesla's Full Self Driving (FSD) (Supervised) mode, when the incident occurred. I was paying close attention while driving in the left-most, non-HOV lane coming up to a bend just before the [XXX] overpass, when I noticed traffic ahead slowing down and coming to a stop. I monitored FSD as it went through the act of braking; however, it seemed to wait a little longer than I would have expected before it actually started to brake, and when it did, the FSD system had to brake more aggressively than I've previously experienced. As it neared the end of the braking event (while the car was still moving), the FSD system disengaged itself without any input from me (neither by manually applying the brake pedal, applying torque to the steering wheel, or pressing the FSD button). When the FSD system disengaged itself, my vehicle continued forward. Had I not been paying attention, my vehicle would have collided with the rear end of the vehicle in front of me. Since I was paying close attention, I immediately slammed on the brakes after noticing that FSD had disengaged itself. I have dashcam footage of this event from the TeslaCam system; however, it does not include audio or telemetry data. Even without that, you can see in the video that my car noses down while FSD applies the brakes, then noses up when FSD disengages itself, and then noses down again when I apply the brakes manually. (The dashcam footage exceeds the 20MB limit; however, I can provide it via other means upon request.) It should be noted that I am an experienced Tesla FSD user, as I used it for over a year in my prior vehicle (2018 Tesla Model 3, which had been upgraded with the HW3 FSD computer), and this is the first time I have ever experienced a near collision event while using FSD or an event in which FSD disengaged on its own.
