Tesla FSD v14.3.7 Fails to Detect Wire Fence, NHTSA Opens Engineering Investigation
An overseas Tesla owner twice had to take emergency control of a vehicle running FSD v14.3.7 in an open-air multi-storey car park after the system failed to detect a wire fence and continued toward the floor edge without warning or automatic braking. The car stopped only after driver intervention, with wheels close to the edge. Tesla's manual notes FSD is supervised assistance, not autonomous driving. NHTSA has opened an engineering investigation into FSD perception failures.
An overseas Tesla owner recently using FSD (version v14.3.7) in an open-air multi-storey parking lot found the vehicle failed to detect a wire fence ahead, triggering no warning or automatic braking as it continued toward the edge of the floor. The driver noticed the anomaly, took over urgently and braked, bringing the car to a stop before the wire fence with the wheels extremely close to the edge. After reactivating FSD, the system again attempted to push through the barrier, but did not succeed.
Tesla's official manual states that FSD is supervised driver assistance, not autonomous driving, and carries a risk of recognition failure when faced with special objects such as thin ropes and thin railings. Drivers are required to monitor the system at all times and be ready to take over. The US National Highway Traffic Safety Administration (NHTSA) is conducting an engineering investigation into FSD perception failures.
