NHTSA Complaint #11388822 — 2017 TESLA MODEL S

MY TESLA IS EXPERIENCING THE MCU PROBLEMS OUTLINED IN NHTSA EA20-003 FROM 13 JAN 21 AND PRIOR. WHILE IN MOTION, ON CITY STREETS AND HIGHWAYS, AND REGARDLESS OF SPEED, MY VEHICLE'S MCU WILL SPONTANEOUSLY AND AT RANDOM INTERVALS FREEZE. THIS RESULTS IN LOSS OF HEAT/COOLING, FRONT AND REAR DEFROSTERS, INFOTAINMENT/GPS, ADAS SAFETY FEATURES AND CONVENIENCE, ALL CAMERAS INCLUDING BACKUP CAMERA, AND TURN SIGNAL AUDIO INDICATORS. THE ONLY RESOLUTION IS TO STOP MY VEHICLE, ISSUE A REBOOT COMMAND, AND WAIT UP TO 10 MINUTES FOR SYSTEMS TO RESTORE. TESLA INITIALLY DENIED THE ISSUE, BUT THEN UNDER TESLA'S 9 NOV 2020 "WARRANTY ADJUSTMENT PROGRAM" REPLACED THE MCU DAUGHTERBOARD. THE REPLACEMENT DID NOT RESOLVE THE ISSUE. TESLA NOW STATES THE MCU IS OPERATING NORMALLY BUT ACKNOWLEDGES THAT A FIX IS REQUIRED IN SOFTWARE THAT WILL, AT AN INDETERMINATE TIME, BECOME AVAILABLE AND THAT UNTIL SUCH A FIX IS RELEASED, SYSTEM REBOOTS SHOULD BE PERFORMED AS NEEDED. THE MCU CONTINUES TO FREEZE WHILE DRIVING WITH THE SAME SYMPTOMS AS BEFORE THE DAUGHTERBOARD REPLACEMENT. THE RECOMMENDED SOLUTION TO REBOOT CANNOT BE PERFORMED WHILE DRIVING BUT MUST BE PERFORMED IMMEDIATELY TO RESTORE SAFETY FUNCTIONALITY. TESLA HAS OFFERED A $2,500 MCU REPLACEMENT/UPGRADE THAT PROMISES TO ELIMINATE THE ISSUE SINCE THE NEWER MCU HAS MORE STORAGE AND AN INTEL ATOM CPU INSTEAD OF A SLOWER NVIDIA CPU. TESLA REFUSES TO REPLACE THE EXISTING MCU WITH A SIMILAR PART IN THE MEANTIME, DESPITE INITIALLY ACKNOWLEDGING AN ISSUE AND ATTEMPTING A FIX BY REPLACING THE DAUGHTERBOARD, AND ERASING THE SYSTEM DUE TO POSSIBLE "CORRUPTION" TWICE.
