Tesla 2026 Model Y was involved in a severe motor vehicle accident directly caused by a critical software and/or hardware malfunction of Tesla’s Full Self-Driving (FSD) system. At the time of the incident, the vehicle’s Full Self-Driving (Supervised) software suite was actively engaged and driving the vehicle. While navigating, the system suffered an abrupt and uncommented control malfunction. Despite prompt attention, the autonomous system executed an erratic, uncorrectable maneuver that overrode human intervention thresholds, completely failed to respond safely to the immediate driving environment, and directly caused a collision.
