NHTSA Complaint #11330617 — 2015 TESLA MODEL S

MCU FAILURE (MARCH 2020) FROM EMMC MEMORY WEAR-OUT RESULTED IN NON-FUNCTIONING CAR. CAR WOULD NOT "TURN OFF," THEREBY ENTIRELY DRAINING BATTERIES. SINCE THE AIR CONDITIONER WAS ON DURING MCU FAILURE, IT WOULD REMAIN ON, NO MATTER WHAT I DID, THEREBY (A) RUNNING DOWN THE BATTERY, AND (B) POTENTIALLY CREATING A MAINTENANCE OR FIRE HAZARD (AC RUNNING FOR 12 HOURS). ALSO NON-FUNCTIONAL WAS CRUISE CONTROL, RADIO, REAR CAMERA, AUDIBLE WARNINGS (LIKE TURN-SIGNAL CLICKS), INABILITY TO CONTROL BATTERY CHARGING, LOSS OF NAVIGATION, PARKING WARNING CHIMES, ENERGY USAGE GRAPH, CELL FEATURES, ETC. SIGNIFICANTLY, THE "CREEP" FEATURE, WHICH MOVES THE CAR FORWARD WHEN PEDAL IS LIFTED, ALSO DID NOT WORK -- CAUSING ME TO HAVE TO RELEARN CERTAIN DRIVE FEATURES, AND AT ONE POINT ALLOWING THE CAR TO ROLL BACKWARD WHEN IT USUALLY WOULD HAVE CREEPED FORWARD. IT'S UNKNOWN IF CERTAIN EMERGENCY BRAKING FEATURES WOULD HAVE WORKED. MAIN VEHICLE CONTROL SYSTEMS FUNCTIONED (STEERING & BRAKES), BUT NOTHING ELSE DID, AND DRIVING WAS VERY CONCERNING. COST TO REPAIR WAS $1575. HOWEVER, THE SAME TYPE OF COMPUTER WAS INSTALLED, WHICH LEADS TO CONCERNS THAT THE SAME PROBLEM MAY OCCUR IN THE FUTURE. SEE ALSO NHTSA ACTION NUMBER: PE20010. *TR
