NHTSA Complaint #11389209 — 2017 TESLA MODEL X

THE CAR HAS 2 DISPLAYS, A DASH DISPLAY AND AN "INFORTAINMENT" DISPLAY. BOTH WORKED GREAT WHEN NEW. ALL VEHICLE STATUS IS DISPLAYED ON THEM, AND MOST VEHICLE CONTROLS ARE AVAILABLE ONLY THROUGH THEM. OVER TIME, THEY HAVE BECOME PROBLEMATIC. THEY WILL SPONTANEOUSLY REBOOT AT ANY TIME (WHILE PARKED IN THE GARAGE, DRIVING UNDER VARIED CONDITIONS, ETC) WHICH CAN MAKE THEM UNAVAILABLE FOR UP TO 3 MINUTES, OR EVEN WORSE THEY WILL FREEZE DISPLAYING THE WRONG INFORMATION UNTIL THE DRIVER NOTICES AND MANUALLY REBOOTS THEM. FOR A WHILE, THIS WOULD HAPPEN ROUGHLY EVERY 10 MINUTES WHILE DRIVING, AND MEANT WE COULD LOSE NAVIGATION WHILE IN AN UNFAMILIAR AREA, LOSE THE BACKUP CAMERA, ACCESS TO HVAC CONTROLS INCLUDING DEFOGGER, ETC. IT IS USUALLY MORE OF AN ANNOYANCE, BUT WITH SUCH FREQUENCY IT IS EXTREMELY ANNOYING AT BEST, AND GIVEN THE RANDOM TIMING IT COULD BE A SAFETY ISSUE AS WELL. WE HAVE HAD 4 APPOINTMENTS TO ADDRESS THIS. THEY HAVE MADE A COUPLE OF CHANGES THAT HAVE REDUCED THE FREQUENCY OF THE PROBLEMS. BUT THEY STILL OCCUR, UNLESS WE COMPLETELY STOP USING MAJOR FEATURES INCLUDING NAVIGATION AND TESLACAM. THE FACT THAT THEY LARGELY DISAPPEAR WITH SOME CHANGES INDICATES THAT THESE ARE NOT DUE TO THE KNOWN EMMC PROBLEMS THAT ARE ALREADY UNDER INVESTIGATION. THESE ARE FIRMWARE BUGS RELATED TO NAVIGATION, USB HANDLING, PROCESSOR OVERLOAD DUE TO NEW FEATURES, ETC. TESLA CLAIMS THEY WILL BE FIXED, BUT CANNOT GIVE US A DATE. THIS HAS BEEN GOING ON FOR ABOUT A YEAR. WE HAVE THIS PROBLEM ALMOST EVERY TIME WE DRIVE THE CAR MORE THAN JUST A FEW MILES. OWNERS ONLINE INDICATE THIS IS A COMMON PROBLEM WITH MODEL X AND S BUILT BEFORE MARCH 2018 WITH THE MCU1 COMPUTER. IT IS CLEAR THAT TESLA SERVICE TECHNICIANS ARE FAMILIAR WITH THE PROBLEMS, AS THEY ARE GIVING SIMILAR EXPLANATIONS TO OWNERS ALL OVER THE COUNTRY. YET THE FIRMWARE BUGS ARE STILL NOT FIXED.
