2017 TESLA MODEL S Lane Departure Blind Spot Detection Problems

My 2017 Tesla S 75D has been having issues with the eMMC/daughterboard main computer/screen/control panel blanking out, where basically the screen that has the majority of controls goes black for a few hours. On one occasion the steering wheel was affected--it locked up. To temporarily remedy the issue, I have to reboot the software/car, but I have to be parked and stopped for 30 minutes to an hour, to go through this procedure. This is a reoccurring problem that started in 2020 and it seems other issues, have stemmed from this. For example, the system has a delay of 1-2 minutes to start up--at every start up; other sporadic issues such as no sound (as in there are no sounds, music, alarms or otherwise, working, at all); the key FOB is delayed in being detected (even after replacing the battery).

THE INSTRUMENT PANEL GOES DARK AND INOPERABLE AT TIMES WHEN DRIVING. ALERTS ARE NOTED THAT VEHICLE SAFETY WARNINGS ARE DISABLED. WE’VE TRIED TO REMEDY WITH THE DEALER NOW ON SEVERAL OCCASIONS AND WE’VE BEEN CHARGED FOR APPOINTMENTS ONLY TO FIND OUT THAT THIS IS A VEHICLE RECALL. DESPITE ALL THESE ATTEMPTS TESLA PALM SPRINGS DEALER KEEPS SAYING THEY WILL LET US KNOW WHEN PARTS TO REPAIR BECOME AVAILABLE. OTHER RATTLING REPAIRS IN CENTER COUNSEL ARE DELAYED PENDING THIS RECALL CORRECTION. BUT WE NEVER HEAR BACK FROM THE DEALER ABOUT THIS CORRECTION. IT SEEMS EXCESSIVE ON THE TIME WAITING TO GET THE COMPONENT/PART TO CORRECT THIS ISSUE. WHAT CAN BE DONE? IT SEEMS LIKE A SAFETY ISSUE TO KEEP DRIVING THE CAR WITHOUT THIS CORRECTION.

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...
