NHTSA complaint #11750627

Owner complaint summary

Component: Lane Support System — Emergency Lane Keeping (ELK) Part of standard Autopilot safety suite (not FSD) activated without valid lane detection data and pushed the vehicle into the oncoming lane of traffic on Ohio State Route [XXX]. The system then aborted mid-intervention (LSS_STATE_ABORT), leaving the driver in the oncoming lane. The resulting head-on collision killed both drivers — the [XXX] Tesla driver and the driver of the oncoming vehicle. Two people died because of this ELK malfunction. Tesla's own telematics data confirms the following sequence: 5At 23:51:17.420 UTC, the Lane Support System activated Emergency Lane Keeping (LSS_STATE_ELK). 6At 23:51:17.652 UTC (232 milliseconds after activation), the system logged ALC_UNAVAILABLE_NO_LANES — confirming it had no valid lane detection data during the intervention. 7At 23:51:17.755 UTC (335 milliseconds after activation), the system logged LSS_STATE_ABORT — the system cancelled itself mid-intervention. 8During the 335-millisecond intervention, the vehicle's steering angle reached -16.79 degrees leftward and lateral acceleration measured +1.200 m/s² leftward — both confirming the vehicle was pushed into the oncoming lane. 9The driver responded with the largest steering torque (-5.08 Nm rightward) and largest rightward steering angle (+19.50 degrees) recorded in the entire telematics file — confirming he was actively attempting to recover. 10 The head-on collision killed both him and the driver of the oncoming vehicle. We requested additional telematics data from Tesla through the Tesla app. A forensic expert has examined the vehicle's ECU motherboard— missing critical fields including continuous yaw rate, high-resolution steering data, ELK steering commands, and lane detection confidence scores. A subsequent request for additional data produced an error message and Tesla has not provided further data. This crash is the exact behavior under PE25012.
