Vehicle: 2019 Tesla Model 3 Dual Motor VIN: [XXX] Mileage: ~84,041 Software: v12 (2025.32.6 e575ed98d527), FSD Supervised v12.6.4 Date/Time: [XXX], ~[XXX] Location: [XXX] Incident Description: While operating Autopilot, I was stopped at a stop sign preparing to turn right. I lightly pressed the accelerator to prompt the turn. At that moment, the vehicle would not respond to steering or braking input. Despite applying full force on the steering wheel and brake pedal, the car continued straight ahead and struck a street sign. This represents a loss of manual override â I was completely locked out of steering and braking. Prior Behavior at Same Location: On prior occasions using Autopilot at this same intersection, the vehicle would attempt to make the turn but then immediately steer itself into the breakdown lane. I had learned to expect this and was prepared to take over. However, in this most recent incident, the vehicle did not allow me to take over at all, which created a far more serious hazard. Result: â¢Vehicle damage (front bumper, sensors) â¢Significant safety risk if pedestrians or cross traffic had been present â¢Demonstrates that Autopilot can both mis-execute turns and, critically, fail to relinquish control when the driver intervenes Action Taken: â¢Scheduled Tesla Service (Cherry Hill, NJ â Oct 7, 2025) â¢Requested Tesla to preserve all telemetry, camera footage, and Autopilot logs â¢Reported to my insurance carrier as a suspected manufacturer de
