Owner's description
While driving on a residential street at night with Full Self-Driving (Supervised) engaged, the vehicle suddenly applied Automatic Emergency Braking without any visible obstacle, vehicle, pedestrian, or hazard present. The braking was abrupt and unexpected and did not correspond to traffic, road conditions, or driver input. No collision occurred, but the sudden stop caused a whiplash effect to occupants, creating a risk of injury despite the absence of an external hazard. The driver immediately disengaged the system after the event. Tesla later reviewed vehicle data and confirmed that an Automatic Emergency Braking event occurred while FSD (Supervised) was active. Tesla identified the software version as FSD v14.2.1 and documented the incident as unexpected emergency braking, with the date, time, location, and environmental conditions recorded.
