NHTSA Complaint #11330649 — 2014 TESLA MODEL S

THE MCU, WHICH IS THE LARGE DISPLAY AND CONTROL SCREEN STARTED TO FAIL. THE HEATING AND VENTILATION CONTROLS DIDN'T WORK PROPERLY, AND THE BLUETOOTH WOULD NOT PRESENT CALL HISTORY, PREVENTING SAFE VEHICLE USE. ABOUT 6 WEEKS AGO, THE MCU FAILED COMPLETELY, WHICH PREVENTED TURNING ON THE HEADLIGHTS MANUALLY. I HAD PREVIOSULY HAD SET THEM TO AUTOMATIC, SO THEY TURNED ON AT NIGHT, BUT I LIVE IN OFF A HIGHWAY WHERE IT IS MANDATORYFOR DAYTIME HEADLIGHT USE, AND I WAS UNABLE TO CONTROL THEM THE FAILURE IN THE MCU WAS DETERMINED TO BE THE EMMC WHICH IS THE SOLID STATE HARD DRIVE IN THE MCU. IT HAS A LIMITED LIFESPAN AND THEY TYPICALLY FAIL WHEN THEY EXCEED THEIR EXPECT NUMBER OF WRITES TO THE DRIVE. TESLA INFORMED ME THAT THEY HAVE CHANGED THE SOFTWARE SO IT DOESN'T WRITE AS MUCH ROUTINE DATA TO THE SSD. I HAD THE MCU REPLACED AT A TESLA SERVICE CENTER ON JUNE 12, 2020, AT A COST OF $2180.06, SINCE MY STANDARD AND EXTENDED WARRANTY HAD EXPIRED. MY TESLA HAS MORE THAN 191,000 MILES ON IT. MOST MANUAL CONTROLS ARE INOPERATIVE, INCLUDING THE BACKUP CAMERA. CONFIGURING THE CAR IS ALSO NOT POSSIBLE.. *TR
