The cable harness (slip ring) connecting the steering wheel controls including the vehicle horn, steering wheel buttons, scroll wheels, and potentially the airbag (according to the service technician) failed on this vehicle in January 2025. The vehicle was inspected by Teslas mobile service and they acknowledged that the cable harness had indeed failed. It is available for inspection. We have been forced to drive this car without a functioning horn and airbag. There were no warning signs or messages on the vehicle computer.
