On July 18, 2026, at approximately 10:00 AM EST, my son was manually driving a 2024 Tesla Model 3 at approximately 26 MPH when the steering suddenly became extremely stiff and difficult to turn. He attempted to steer away from a roadside barrier but was unable to turn the steering wheel sufficiently, resulting in a collision. There was no warning or indication observed on the dashboard before the steering suddenly became extremely stiff. Autopilot, cruise control, and Full Self-Driving were not activated; the vehicle was being driven manually. Fortunately, my son did not sustain any physical injuries. However, a sudden loss of normal steering control is a serious safety concern and could potentially cause severe injuries to the driver, passengers, pedestrians, or occupants of other vehicles. After the accident, the vehicle was towed to the insurance-designated facility and is currently being examined by the insurance adjuster. Within a few minutes of the accident, the vehicle also became completely locked, preventing us from retrieving personal belongings. I previously reported this incident to NHTSA under complaint number 11751698, but all required documentation was not available at that time. I am therefore submitting the complaint again with the additional information and documentation now available. I respectfully request that NHTSA investigate this incident and determine the root cause of the sudden steering stiffness and whether there is a safety-related defect or
