On March 14, 2026, at 20:54:21 UTC, while the Autopilot system was engaged, the vehicle malfunctioned by initiating a sudden, unprompted right-hand steering command within 0.3 seconds, resulting in a collision with another vehicle traveling in the adjacent right lane. Telemetry data from the event confirms the system failed to maintain the lane despite the Primary Steering Torque Sensor measuring 0.00 Nm, proving no driver input caused the maneuver. This unintended steering event at cruising speed created an immediate safety risk to myself and the occupants of the other vehicle. To date, the manufacturer (Tesla) has declined to perform a technical or remote diagnostic review, redirecting the case to a collision center instead. No warning lamps, audio chimes, or system messages occurred prior to the failure; the vehicle is currently available for inspection and raw CSV telemetry logs can be provided to investigators upon request.
