NHTSA put some pressure on Tesla after the owners of older Tesla Model S and Model X vehicles have been reporting some issues with their MCUs.
The issue is about a less responsive touchscreen, longer power-up time, the screen freezing that requires a constant reboot. The worse version of these is the total failure of the MCU unit.
The 2018 MCU doesn’t have this problem at all. This year, National Highway Traffic Safety Administration (NHTSA) into the matter and Tesla finally acknowledges the issue and offers an extended warranty on the 8GB embedded MultiMediaCard (“8GB eMMC”).
Tesla acknowledged the problem for the first time, emailed and informed their clients that it is adjusting its warranty to “repair or replace the 8GB eMMC free of charge at any Tesla Service Center” for owners of Model S and X. The conditions are that the car was built before March 2018, has less than 100,000 total odometer miles, and within eight years starting from the date the vehicle was first put into service or delivered by Tesla to the first purchaser/lessor.
