Consumer Description

VEHICLES MEDIA CONTROL UNIT (MCU) HAS A KNOWN AND WELL-PUBLICIZED DEFECT CAUSED BY OVER-LOGGING ON THE EMMC CHIP. THIS DEFECT CAUSES THE MCU TO GLITCH, REBOOT AND FAIL ELIMINATING THE ABILITY TO CONTROL BOTH SAFETY AND CONVENIENCE FEATURES INCLUDING CLIMATE CONTROL, DEFROSTER, GPS, AUDIBLE SAFETY WARNINGS AND OTHER SYSTEMS. VEHICLE CAN ALSO STOP CHARGING. THIS IS A WELL-DOCUMENTED DESIGN FLAW THAT TESLA IS WELL AWARE OF (SIMPLY GOOGLE TESLA MCU FAILURE) BUT REFUSES TO COVER OUT OF WARRANTY. THE MOST RECENT "FIX" VIA AN OVER THE AIR UPDATE SIMPLY DELAYS THE ISSUE UNTIL VEHICLE IS OUT OF WARRANTY BUT BASED ON CURRENT EVIDENCE THIS DEFECT WILL EFFECT 100% OF CARS, BOTH MODEL S AND X, MADE BETWEEN 2012 AND EARLY 2018.
