Model S and Model X owners rejoice on February 2, 2021, 16:52 Cutting corners: It took the intervention of the National Highway Traffic Safety Administration (NHTSA) for this to happen, but Tesla has issued a formal recall for Model S and Model X vehicles that are equipped with media control units that are prone to failure. Last month, the NHTSA asked Tesla to recall no less than 158,000 Model S and Model X vehicles, citing concerns over the safety of the media control unit (MCU), whose touchscreen display is prone to failing. Following a thorough investigation, regulators concluded that this was a potentially serious issue as it leads to loss of important vehicle functions like Autopilot audible chimes, turn signals, windshield defogging, and access to the rearview backup camera display.
