NHTSA complaint #11747048

Owner complaint summary

My 2023 Tesla Model 3 (VIN [XXX]) has a recurring safety defect in its driver-assistance system involving two unsafe behaviors. First, “phantom braking”: while driving with Autopilot/FSD engaged, the vehicle decelerates suddenly and without warning when there is no obstacle or threat in its path, creating a rear-end collision risk. This was first reported within the vehicle’s warranty period and has recurred. Second, on the most recent occurrence, with a Tesla service technician riding along to witness the issue, Full Self Driving (Supervised) failed to proceed safely through the intersection of [XXX] and [XXX]. The vehicle stopped mid-turn while another vehicle approached from the opposite direction. I had to take manual control to complete the turn and avoid a hazard. The Tesla technician witnessed this directly, and the service summary states FSD “did not proceed through the intersection properly.” The vehicle has been to a Tesla service center twice for this defect. It has not been resolved. The behavior occurs without warning and is unpredictable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
