Tesla Model S, Model X: Electrical
Affects Tesla Model S, Model X · 2012–2018 — about 9K vehicles.
The hazard
Issue: On certain vehicles, the internal memory for the media control unit (MCU) could run out of storage capacity over time. If this happens, the center display can turn off while driving and cause some of the car's systems not to work properly. This includes the rearview camera display, defrost/defog control settings, and exterior turn signal lighting. Safety Risk: A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. A windshield that cannot be defrosted/defogged could reduce visibility. Turn signals that do not work could cause a following driver not to recognize that a vehicle ahead intends to turn. These conditions could increase the risk of a crash. Corrective Actions: Tesla advises owners to ensure that their vehicle software is up to date. Tesla will notify owners by email, including when parts are available to schedule service to upgrade the internal memory in the MCU.
