2017 TESLA MODEL S Electrical System Problems

This is a supplemental filing to my prior NHTSA complaint (#11697718) regarding a high-voltage isolation fault and shutdown risk. The vehicle displayed warnings including “vehicle may shut down during driving,” “may not charge,” and repeated BMS isolation fault messages. It became inoperable at a public charging station. The manufacturer confirmed isolation faults in the drive unit and the A/C compressor. Their own service notes stated that the vehicle “may shut down during regular driving” and that charging “may not be safe.” Despite this, the vehicle was left at 0% state of charge for an extended period and then charged by the manufacturer. They later stated to a regulator that the vehicle was “trickle charged at 1 amp for 6 hours,” but the vehicle’s range increased by approximately 100 miles, which is not physically possible at that charging current (1 amp at 240V for 6 hours = 1.44 kWh ≈ 4–5...

This is an update to NHTSA Complaint #XXX with new safety information. My 2017 Tesla Model S (VIN [XXX] ) has a confirmed high-voltage isolation fault. Tesla replaced the rear drive unit under warranty, but Tesla’s own technician notes now state: “There is a risk of isolation alerts reoccurring during regular driving, use of HVAC system, or DC charging.” “Vehicle may power off due to isolation faults when the air conditioning is used.” This is Tesla acknowledging in writing that the vehicle may shut off during normal driving, even after repair. This presents a serious crash risk. The original failure occurred during Supercharging, with warnings including: • “Electrical system power reduced — vehicle may shut down unexpectedly” • “Vehicle may not restart” • “Air conditioning reduced — DC charging reduced” Tesla reproduced the isolation fault during diagnosis. Even after replacing the rear drive unit, Tesla documented that the isolation defect...

While charging at a Tesla Supercharger, the vehicle began making extremely loud mechanical noises on October 7, 2025, as if something inside the high-voltage system was about to explode. A warning appeared stating “Vehicle may shut down at any time.” A service request was opened the next day. Tesla scheduled the first available appointment nearly a month later, leaving the vehicle unsafe to drive. Before that appointment date, on October 31, 2025, the vehicle completely shut down at a Supercharger and could not be restarted. Tesla Roadside Assistance was dispatched three times before the car was successfully towed to a Tesla Service Center. The failure was diagnosed by the service center as a high-voltage isolation fault logged in the Battery Management System. The problem disables the vehicle suddenly and without warning, posing a serious safety hazard if it occurs while driving. Warning lamps and shutdown messages were present prior to...

I have documented examples of 3 total incidents now where a Tesla OTA "Update" on my vehicle caused a safety issue. Event 1: Nov 27, 2025. Tesla OTA Update renders my left turn light non-functional for ~24 hours. Resolution per forums only was to not touch the card for 24 hours to allow it to shift into "sleep" mode which would resolve the issue. Instructions were that only a service center could resolve the issue. Event 2: Sept 3, 2025. Tesla OTA Update renders my car unable to charge. The issue is resolved following a ~24 hour "sleep" cycle which allows my car to somehow resume charging. Telsa advised the only resolution was to come in for service and to replace a $3000 part. Event 3: Sept 23, 2025. Tesla OTA Update once again renders my car unable to use it's left turn light. Power cycling the vehicle was able...

Tesla originally confirmed issues with the MCU1 system in my vehicle and upgraded it to MCU2. I Paid $1,599 for the repair/upgrade. Since then, the center screen has continued shutting off while driving. When this happens, the instrument cluster and controls go dark, I cannot see my speed, use the blinkers to signal, operate the AC/defroster, or access other critical vehicle functions. This has occurred multiple times on highways, including US-22 in New Jersey, which created serious danger because I could not monitor speed or signal properly. Although Tesla addressed the MCU1 problem by upgrading me to MCU2, they told me afterward the vehicle was still “safe to drive,” despite the failures continuing. I believe this is unsafe because I lose visibility of all driving information and access to basic controls. Tesla now refuses to repair these ongoing problems. After I raised complaints about the severity of the issue, I...

While in autosteer, I pressed on the brakes which normally deactivates the autosteer while coming to a stop. In this particular case the car did not brake upon command and the car maintained acceleration thru a stop light and veered into a median causing a collision with a curb causing structural damage to the frame of the vehicle. I have put in a claim with both my insurance and Tesla and advise that the brakes did not activate in a timely fashion upon disengaging from Autosteer thus causing the collision and was advise by Tesla that I would be responsible to cover the damages when the accident was caused by the vehicle not disengaging. I was only advised after the fact of the recall for the very reason I complained to Tesla in the first place and have been waiting 5 months for a resolution.

The contact owns a 2017 Tesla Model S. The contact received notification of NHTSA Campaign Number: 23V838000 (Electrical System) however, the contact was informed by the dealer, that the computer needed to be updated from Media Control Unit 1 to Media Control Unit 2 to receive proper software updates. The contact stated the vehicle was using the latest autosteer computer software however, the infotainment was using on the Media Control Unit 1 computer which was no longer receiving software updates or safety updates. The contact stated that the computer was able to receive updates, however, the manufacturer chose not to write codes for the older computers due to the cost. The vehicle was not updated version 2022.8.10.16 to the necessary version 2023.44.30 or later due to the cost. The approximate failure mileage was 91,840.

The screen that shows the rear view camera turns on intermittently when engaged. It will often not turn on when shipped to reverse. The sentry system has stopped working as well as the main screen will shut off while driving from time to time, which removes the ability to turn on any heat or air, defroster etc... This was a previous recall and I am a new purchaser of the vehicle. I notified Tesla, they stated that they see where it is having issues but it was already recalled and fixed and any new fixes are no longer under the recall.

The back-up camera is not functioning. I get a black screen whenever I put the car in reverse. I can use the mirrors but the visibility behind the car is not very good. This makes it much ch more difficult to back out and avoid other cars and pedestrians. I have tried to reset/restart the various software systems with no improvement. I understand there is a recall for other Model 3 and Model S cars, I don’t u sweats d how my VIN is not covered as it has tb exact same issue as reported for the recall.

This is a 2017 Tesla Model S with 31K miles. The vehicle has lost its ability to charge on ny AC current. Only charges with DC from Tesla supercharger. Service told me that I needed a replacement part (Kit, Service, Gen3, charge sys, 48A, 1PH (1462537-02-E). Invoiced amount was $2500. Tesla refused to cover under 8 year battery warranty even though the problem is directly related to charging the battery.

The emergency trunk release does not work when the cinch motor fails on the power tailgate. Part is scheduled to be replaced by Tesla.

coolant leaking, before tesla can even look at my car they say i need new valves. Only way they could know this is if there is a faulty part. This should be a recall! Believe this is the Battery coolant.

Tesla designs a single piece headlight with no serviceable parts. This includes headlights, high beams, and namely daytime running lights. All of these components are on an LED strip that overheats and un-solders due to this high heat, which causes premature failure. Some owners have reported as little as 3 months of life before failing. The daytime running lights are essential for safety driving in low light situations. These daytime running lights are seemingly built to fail. The lights dim then eventually no longer work. Tesla's solution is to have the customer purchase a brand new headlight at $1438.33. My vehicle is 4 years old and has been through. Tesla should either goodwill swap out these headlights for a non-built to fail component, or offer a repair for a quality LED strip with proper heat distribution. Without daytime running lights safety is a major concern on foggy, rainy, and low...

Went to back into charger and back up camera still showed photo from where car was parked at home before I started my trip. I noticed a car behind me in mirror but picture showed no cars (and wrong location).

The car had multiple computer issues causing it to break unexpectedly, turn unexpectedly, avoid things that were not there unexpectedly. It was brought into the dealer multiple times, who actually viewed the error, and when they were driving it, they were involved in an auto accident. Even with the warranty, they could never fix it, and it was amazingly dangerous almost killing me several times.

My vehicle driver door handle keeps popping open while parked and while driving. The door handle will either present itself or Not when this occurs. Disallowing me keep door shut. Also, door stays shut as times and doesn’t not present itself and makes a mechanical sound. This is a HUGE safety concern. I was advised since my warranty is up, it’s on me to fix, however, this is a safety defect and I am wanting to escalate ASAP before I have an accident from the door opening.

On March 22, 2021 Tesla announced a recall of the 8GB MultimediaCard (eMMC) for my 2017 Tesla Model S. It causes the main touchscreen to go fail, rear camera to fail, lose of control of radio/defrost and all other commands that require this touch screen. Tesla said they would replace the eMMC. That was almost a year ago. My vehicle has experienced this failure multiple times both before and after the notice and yet still nothing. I actually took my car in for this failure in Nov 2020 and was told nothing was wrong. Its an intermittent failure which requires a reboot to fix temporarily.

Four separate issues to report: 1.) multiple instances of car braking while in self-drive mode. This has included driving at high speeds on highway and having vehicle slam on brakes nearly causing an accident. I took over as I was paying attention on all occasions. 2.) While is self-drive mode and a lane widens, car veers to “middle” of wide lane. This does not act in a way a normal driver would. 3.) Issues with middle screen stopping or resetting during driving. This was a reported recall issue and I did get the recall taken care of. Issue still persists. Tesla has not been responsive in getting this resolved. 4.) Recent issue with main screen panel behind steering wheel resetting while driving. Vehicle maintained operations, but I could not see speed or change gears while driving. This has happened before. Tesla updated CPU, issues persists.

The contact owns a 2017 Tesla Model S. The contact stated that on three separate occasions while driving at highway speeds with cruise control engaged, the vehicle would suddenly brake on its own. The contact was uncertain if any warning lights would appear on the instrument panel prior to the failure. The service center nor the manufacturer had yet to be notified of the failure. The contact stated that he was able to document the exact time that the latest failure occurred on the vehicle. The vehicle had yet to be repaired. The failure mileage was approximately 48,000.

The scroll wheel on the steering wheel failed which prevents the vehicle display from showing critical information. This scroll wheels are also used to reboot the computer when the system fails so it is a safety concern that needs to be addressed. Many Tesla owners have had a similar failure of the scroll wheels and a disassembly of the component clearly shows a defect in the manufacture of the part in that it has a thin extension that breaks due to normal use and as a result, failure of the scroll wheel is highly probable.

I am asking [XXX] a mgr. at Centinela Tesla for a refund of the money I spent on an upgrade for the model S which after being installed began shutting down intermittently. Tesla's system records all shutdowns of the cars screens, so If Tesla does not have records of the cars screens shutting down prior to the upgrade, this would indicate it did begin with the upgrade.  The NHTSA made a recall for an issue with the back up cameras which was when TESLA offered me a 1500.00 dollar upgrade instead of the free NHTSA recall fix, saying it was better.  A [XXX] at Torrance Tesla said he saw 2 shutdowns recorded in the week prior and did not have time to look up beyond that week.. [XXX] gave me a free accessory saying sorry for your problems but this is all I can do.  The receipt for the free...

The main screen will go blank, turn off and not reboot up. The rear camera will not turn on, or turn off during backing up. Car will not boot up for several minutes.

Compter screen goes black. I loose all functions . Its the same issue that is noted in the CR recall summary. However, they want to charge me 2000 to fix the firmware problems. Furthermore, the car has an extended warranty that apparently they won't honor.

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.

BELOW IS THE LIST OF DATES I'VE EMAILED ABOUT ISSUES REGARDING AUTOPILOT AND TOUCHSCREEN, AND MICROPHONE ISSUES. THE FIRST REPORTING OF IT WAS LESS THAN A MONTH AFTER PURCHASE: 10.19.2017. I HAVE ALL OF THE EMAILS AND VIDEOS (WITHIN EMAILS) TO PROVE ALL OF MY STATEMENTS ABOUT PROBLEMS WITH AP AND THE TOUCHSCREEN, ALONG WITH MICROPHONE ISSUES. I CAN PROVIDE THE SPREADSHEET OF THE DATA IF YOU NEED IT. NOW THAT TESLA HAS ACKNOWLEDGED A PROBLEM WITH THE E-MMC UNIT WITHIN MY TESLA, THEIR SERVICE CENTER NOW STATES IT IS ON BACKORDER AND THEY HAVE NO IDEA OF WHEN IT MAY BE AVAILABLE. THEIR MOST RECENT LETTER DATED 3.22.21 STATES "PARTS TO REPLACE THE VCM DAUGHTERBOARD ON YOUR VEHICLE ARE NOT YET AVAILABLE." HOWEVER, IF I PAY $1,500 FOR THE COST OF THE INFOTAINMENT UPGRADE, THEY CAN DO IT WITHIN A WEEK! I SHOULDN'T HAVE TO PAY TO HAVE THIS...

NHTSA RECALL #21V035. MY TOUCH SCREEN, FANS, BLINKERS AND LIGHTS HAVE GONE OUT WHILE DRIVING 4 TIMES IN THE LAST MONTH, IN MOTION ON CITY STREETS AND ON THE HIGHWAY. TESLA SAYS THEY DO NOT HAVE PARTS TO FIX IT. THE RECALL STATES THE FIX IS TO BE AVAILABLE STARTING MARCH. WHAT CAN BE DONE TO FORCE TESLA TO ACTUALLY FIX THE CAR?

I COMPLAIN THAT TESLA FAILED TO REMEDY THE DEFECT OF MALFUNCTIONING EMMC BY REPLACING VCM DAUGHTERBOARD (SEE THE LETTER RECEIVED) WITHIN A REASONABLE TIME FRAME. SINCE LAST NOVEMBER I HAVE RECEIVED A NUMBER OF LETTERS FROM TESLA INFORMING THE RECALL AND NOTHING HAPPENED.

I HAD TO REPLACE CHARGING SYSTEM WITH TOTAL EXPENSE OF 2589.75. UNFORTUNATELY THE CHARGING SYSTEM THAT IS PART OF BATTERY, IS NOT COVERED UNDER WARRANTY AS LONG AS THE BATTERY. MY MILEAGE WAS 56814. ALL MY SAVINGS FROM GAS AND REGULAR MAINTENANCE COSTS IS EVAPORATED. I UNDERSTAND THAT THERE ARE SEVERAL PEOPLE HAD THE SAME ISSUE. THE CHARGING SYSTEM IS NOT LASTING AS LING AS THE BATTERY. I FIND IT TESLA'S SELLING POINT OF " POTENTIAL SAVINGS" IS MISLEADING. I AM NOT SURE IF ANYONE OUT THERE MADE THE SAVINGS BY OWNING THE CAR AS MUCH AS IT CLAIMS. IN MY OPINION TESLA SHOULD REMOVE THE POTENTIAL SAVINGS CL;AIM TOTALLY. ITS JUST A UNREALISTIC AND MISLEADING CLAIM.

THIS WAS ISSUED A FULL RECALL BY NHSTA. THE VENDOR, TESLA INDICTED ONLY A COUPLE OF WEEKS BEFORE A CHIP REPLACEMENT WAS AVAILABLE. TO DATE NO REPAIR HAS BEEN MADE AND THE VENDOR IS NON RESPONSIVE. YOUR HELP NEED TO EFFECT THIS RECALL

TL* THE CONTACT OWNS A 2017 TESLA MODEL S. THE CONTACT STATED WHILE DRIVING 50 MPH, THE MEDIA CONTROL UNIT BECAME INOPERABLE CAUSING SEVERAL OTHER ELECTRICAL FUNCTIONS TO FAIL TO OPERATE AS NEEDED. THE CONTACT STATED THAT THE FAILURE CAUSED THE TURN SIGNALS TO NOT FUNCTION AS NEEDED. THE CONTACT STATED THAT THE FAILURE WAS INTERMITTENT. THE CONTACT TOOK THE VEHICLE TO THE LOCAL DEALER TESLA-BELLEVUE (14408 NE 20TH ST, BELLEVUE, WA 98007) AND THE MCU MODULE VERSION 1 WAS REPLACED WITH VERSION 2 HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 38,000.

SINCE LAST YEAR, I'VE BEEN HAVING FREQUENT(6-8WEEKS) ISSUES WITH THIS CAR ALL CENTRAL TOUCHSCREEN RELATED. IT STARTED SMALL BUT KEEPS GETTING BIGGER AND BIGGER. I DON'T DRIVE MUCH SINCE COVID AND I THINK IF THAT WASN'T THE CASE THE ISSUE WOULD'VE BEEN UNBEARABLE. LAST NOVEMBER IT WAS JUST THE SCREEN SHUTTING DOWN WHILE DRIVING. THIS JAN/FEB THE ISSUE WORSENED WHERE THE SCREEN/LIGHTS ACTED LIKE THEY WERE POSSESSED, THE CENTRAL SCREEN DISPLAY SHOWED A BATTERY WARNING TO PULL OVER AS THE CAR IS ABOUT TO DIE EVEN THE OTHER SCREEN SHOWED OVER 200MILES LEFT. THE WORST OF IT ALL, I WAS ON A NARROW STREET(1LANE EACH) GOING HOME, I HAD NO NOISE NO MUSIC IN THE CAR. THE CAR WENT FROM SILENT TO EXTREMELY LOUD ON ITS OWN. EVERY SINGLE ALARM WARNING SOUND IN THE CAR STARTED AT THE EXACT SAME TIME AT FULL VOLUME. STARTLED, I VEERED OFF THE ROAD...

THE CENTRAL SCREEN WENT BLANK I TOOK TO THE DEALER THEY TRIED TO FIX IT IT HAPPENED TWICE THE WIPERS AND AC CONTINUED TO RUN EVEN WHEN I GOT OUT OF THE CAR LAST TIME IT HAPPENED AT THE REPAIR SHOP THE ODOMETER MILEAGE JUMPED FROM 21 000 TO 58 000 I TOOK THE CAR BACK TO REPAIR SHOP AND THEY SAID IT IS A COMPUTER GLITCH AND FIXED (?) THE PROBLEM AND MILEAGE WAS ADJUSTED I AM WONDERING IF MILEAGE CAN BE ADJUSTED BY THE DEALER , I THINK IT IS ILLEGAL. INTERMITTENTLY THE CAMERAS ARE FOGGING EVEN WHEN IT IS NOT COLD. NO CLEAR EXPLANATION GIVEN BY THE CREW AT REPAIR PLACE

MY ON BOARD MCU, MAIN SCREEN KEEPS GOING BLANK WHILE DRIVING. THIS CAUSES THE LOSS OF FUNCTIONALITY OF MY VEHICLE CONTROLS. I LOSE CONTROL OF THE DEFROST AND OTHER CLIMATE FUNCTIONS. ONE MORNING WHILE DRIVING IN EXTREME FOG AND HIGH HUMIDITY I COULD BARELY SEE BECAUSE I COULD NOT CONTROL THE DEFROST FUNCTION. HAVING THE MAIN SCREEN GO OUT ALSO CAUSES A LARGE DISTRACTION

I HAVE BEEN REACHING OUT TO TESLA SERVICE CENTER REPEATEDLY REGARDING THE EMMC UNIT FAILURE WHERE IT HAS GONE COMPLETELY BLANK AND TURNS OFF DURING MY DRIVE SEVERAL TIMES. I LOSE ALL AIR CONTROL, BLUETOOTH, REARVIEW CAMERA, AND EVERYTHING THAT THE MAIN MCU UNIT CONTROLS. I HAVE HAD THIS HAPPEN WHEN IT WAS VERY COLD OUTSIDE DURING THE NIGHT WHEN I LOST VISIBILITY DUE TO THE FOGGING INSIDE AND NO DEFOGGING CONTROL AVAILABLE. I CONTACTED THE SERVICE CENTER IMMEDIATELY ON DECEMBER 22, 2020 AND MADE AN APPOINTMENT, WHICH THEY DIAGNOSED VIA LOGS ON THEIR END AND NEVER AGREED TO PHYSICALLY DIAGNOSE MY CAR IN PERSON. THEY KEEP CLAIMING THAT THIS IS AN ISSUE THAT WILL BE ADDRESSED IN A FUTURE FIRMWARE UPGRADE, FOR WHICH THEY DO NOT KNOW THE TIMELINE AT ALL SINCE THE ENGINEERS ARE STILL WORKING ON IT, AND THAT THIS IS NOT A HARDWARE ISSUE. I DETAILED...

MCU UNIT GOES BLANK AND HAS DIFFICULTY COMING BACK ONLINE, WHICH PRECLUDES ME FROM SAFELY DRIVING MY CAR; THE CAR WAS STATIONARY.

CENTER CONSOLE GETS BLACK SCREEN OCCURRENCES AND LOSS OF AUDIO HAS HAPPENED AT LEAST 15-20 TIMES. PURCHASED CAR FROM TESLA IN MID OCTOBER. SCREEN ISSUES SINCE HAVING THE CAR AND NO AUDIO, TESLA STATES TO PATIENTLY AWAIT FE UPDATE HAVE HAD THE CAR SERVICED MULTIPLE TIMES FOR THE ISSUE. SEVERAL APPOINTMENTS CANCELED BY TESLA STATING THERE IS NO FIX AND TO PERFORM RESET ON CAR WHICH IM NOW DOING EVERY 5-10 DAYS.THIS HAS HAPPENED WHILE VEHICLE WAS STATIONARY IN PARK AND HAVE HAD TO DRIVE MULTIPLE TIMES ON THE FREEWAY AND SURFACE ROADS WITH NO SCREEN OR AUDIO. HAS OCCURRED 11-17-20, 11-28-20, 12-8-20, 12-19-20, 1-2-21, 1-8,21,. WHEN BLACK SCREEN OCCURS NO WARNING CHIMES OR AUDIO PRESENT. TESLA REFUSES TO ADDRESS THE HE ISSUE DESPITE BEING AWARE OF IT AND HAVING BEEN GIVING EXACT DATES OF OCCUPANCIES PICTURES OF BLACK SCREEN ETC.

MULTIPLE FUNCTIONS ARE NO LONGER WORKING IN CAR. THE SCREEN HASN'T HAD A YELLOW FRAME AROUND IT FOR NEARLY A YEAR.THEY REPLACE THE FIRST ONE UNDER WARRANTY AND THEN IT DID IT AGAIN WHILE IT WAS STILL UNDER WARRANTY AND THEY TOLD ME THAT IF I WANTED IT REPLACED I WAS TO PAY OUT-OF-POCKET. SO I HAD THEM NOTE IN THE NOTES THAT MY CAR NEEDED A SCREEN EVEN THOUGH THE WARRANTY WAS TO FALL OUT. MULTIPLE FUNCTIONS NO LONGER WORK. CERTAIN CLIMATE CONTROL FEATURES DON'T WORK. MOBILE APP NO LONGER WORKS WITH VEHICLE ON MOST FUNCTIONS. SCREEN SOMETIMES STAYS BLACK AND DOES NOT BOOT UP. MAYBE STUCK FOR MULTIPLE MINUTES WHILE CAR IS BOOTING UP. MOST OF THE TIME WHEN THE SCREEN GIVES US PROBLEMS IT IS NOT WHEN DRIVING. IT IS USUALLY WHEN WE FIRST GET INTO THE VEHICLE. WE HAVE HAD ONE OCCURRENCE WHERE THE SCREEN SHUT...

THE TESLA MODEL S MAIN SCREEN BLACKED OUT, CAUSING ME TO NOT HAVE ACCESS TO ANY OF THE CAR'S CONTROL SYSTEM OTHER THAN TO DRIVE IT (NO BACKUP CAMERA, CLIMATE CONTROL, MUSIC, DOOR LOCKING, SUSPENSION ADJUSTING, TURN SIGNAL CHIMING, AND OTHER ESSENTIAL SAFETY FEATUES). WHEN I TOOK IT TO TESLA, THEY IDENTIFIED THE PROBLEM BUT TOLD ME TO FIX THE ROOT OF IT, I'D HAVE TO PAY FOR AN "MCU2 UPGRADE" OF OVER $1000 EVEN THOUGH THEY KNOW THE COMPUTER CHIP IS BAD (AND WILL GO BAD AGAIN). THIS HAPPENS SOMETIMES WHILE THE CAR IS PARKED AND OTHER TIMES WHEN IN MOTION.

OWN TESLA MODEL S FOR 4 YRS NOW AND FOR LAST 3 MONTHS I HAVE STARTED NOTICING THAT THE MCU (TOUCHSCREEN) DOESN'T POWER UP AND SOMETIMES I HAVE TO WAIT FOR 5-10 MINUTES FOR CAR TO POWER ON. I HAVE REPORTED 4-5 OCCURRENCES OF THIS ISSUE TO TESLA ALREADY BUT EVERYTIME THEY PUSHED BACK CITING IT IS NOT MCU RELATED. IN FACT I REPORTED THEM THAT THIS SEEMS TO BE PART OF NHTSA RECALL ISSUE SENT OUT TO TESLA ASKING TO REPLACE MCUS FOR 2017/2018 MAKES BUT TESLA HAS NOT TAKE ANY ACTION YET. I REPORTED ANOTHER OCCURENCE OF IT TODAY AGAIN AND SCHEDULED AN APPOINTMENT WITH TESLA SERVICE ON 11TH FEB,21. THIS COULD POTENTIALLY BE A SAFETY ISSUE IF THERE IS AN EMERGENCY AND MY CAR WON'T POWER UP. REQUEST NHTSA TO INTERVENE AND GET MY MCU ISSUE RESOLVED BY LIASONING WITH TESLA TEAM AS I HAVE TRIED MY...

MEDIA CONTROL UNIT 1 SOFTWARE KEPT CRASHING AND FAILING. POSSIBLE ROOT CAUSE IS FPGA AND/OR MMCU. SPENT $2500 TO REPLACE WITH MCU2 TO HELP ELIMINATE ISSUE. SEEMS LIKE LOTS OF OWNERS ARE HAVING SIMILAR ISSUES.

MY SCREEN KEEPS FREEZING AND IS BLACK CAUSING A SAFETY HAZARD AND I CAN'T DRIVE THE CAR ANYMORE. I HAVE TAKEN THE CAR TO TESLA SEVERAL TIMES BUT THEY WON'T FIX IT. THE COMPUTER IS BROKEN AND THE CHIP HAS FAILED. THE AC DOESN'T WORK, I CAN'T CONTROL MY RADIO, MY BACK UP CAMERA DOESN'T WORK, TURN SIGNALS DON'T WORK, HANDS FREE SYSTEM DOESN'T WORK, NAV SYSTEM DOESN'T WORK. TESLA NEEDS TO REPLACE MY ENTIRE NAV, ENTERTAINMENT COMPUTER TO RETURN THE CAR TO WHAT I ACTUALLY PAID FOR. THE CLOCK DOESN'T WORK, AND I CAN'T TELL HOW MUCH BATTERY LIFE I HAVE LEFT. THIS IS A DANGEROUS SITUATION AND THEY HAVE REFUSED TO REPAIR THEN COMPUTER. THIS IS AN ELECTRIC CAR AND 100% RELIES ON THE COMPUTER TO CONTROL EVEN THE SMALLEST DETAILS. I CANNOT DRIVE THE CAR AND TRY TO REBOOT THE CAR WHILE I'M DRIVING. NOTHING HAS WORKED....
