NHTSA complaint #11751194

Owner complaint summary

On XXX, while Full Self-Driving (Supervised) was engaged, my 2022 Tesla Model 3 RWD abruptly decelerated without any visible vehicle, pedestrian, debris, or other obstacle requiring braking. Based on my best recollection, this occurred on approximately five separate occasions in clear daylight with clean cameras. On XXX, the first event occurred near XXX while traveling from [XXX] toward the [XXX]/[XXX] area. I took manual control for about 30 minutes. After I re-engaged FSD, a second event occurred and included approximately three rapid braking pulses. The occupants lunged forward during both episodes. On XXX, the drive from [XXX] to the Ukiah Costco was normal. On the return toward [XXX], FSD suddenly braked hard at approximately 63 mph and reduced the vehicle's speed by about 25 mph, to approximately 38 mph. Family members and friends in the vehicle were startled and moved forward. Later that day, there were two additional unexpected braking episodes while traveling from XXX toward XXX. I used accelerator input to override the unwanted braking. The unexpected highway-speed deceleration created a risk of being struck from behind and made the system unpredictable to supervise. No crash, fire, injury, or property damage occurred. I do not recall a warning message before the braking. The vehicle has not been inspected or diagnosed for this issue and is available for inspection upon request. As of XXX, the vehicle reports Tesla software 2026.20.3 and FSD (Supervised) v12.6.4; it has Hardware 3. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
