On October 17, 2025, while Full Self-Driving (Supervised) was engaged, the vehicle made an abrupt, uncommanded steering input to the right, causing a collision with a tunnel wall. This crash appears to be the result of a critical vehicle hardware failure. In the 24 hours prior to the crash, the vehicle logged multiple critical steering errors, including EPAS3P_a086_dasMia, which indicates the Electric Power Assisted Steering system was "Missing in Action" and not communicating. Furthermore, the vehicle has logged daily, recurring hardware faults for the Steering Column Control Module (SCCM_a016_hardwareError) since it was purchased. The uncommanded steering action created an extremely dangerous safety condition resulting in a collision. All stability and traction control faults appeared at the exact moment of impact, not before, indicating the steering system failure was the root cause. The problem has been confirmed by the vehicle's own internal diagnostic logs. The vehicle is available for inspection.
