This all started back in 2012 but only now has Tesla admitted to the problem. Even the National Highway Transportation Safety Administration (NHTSA) had to get involved. The California-based automaker has finally acknowledged there were Media Control Unit (MCU) touchscreen failures on the 2012 to 2015 Tesla Model S and Model X. In many cases, owners were left with a useless touchscreen but Tesla claimed it wasn’t covered under warranty.
That’s been changed now as the company has announced, via Electrek, an extended warranty for its older MSU touchscreen. A new MCU arrived in 2018 and has not experienced the same issues, which included slowed overall response, a longer power-up time, and a systems freeze that required a reboot, and in many cases, a complete failure. The cause, some affected owners believe, can be traced to the embedded Multi-Media Card memory in the MCU.
