2014 TESLA MODEL S Electrical System Problems

TOUCH SCREEN INTERFACE TO MANY CONTROLS DOES NOT POWER UP FOR PAST 3 MONTHS SINCE EARLY JUNE 2020. TURN SIGNAL DOES NOT OPERATE, AIR CONDITIONING CONTROLS NOT AVAILABLE, CAR CHARGE RATE IS DEFAULTED TO 8 AMPS ONLY - THINK THIS PREVENTS ROAD TRIPS AS CHARGING WOULD TAKE FULL DAY TO CHARGE, WAITING FOR REPAIR.FROM TESLA FOR 3 MONTHS AND FINALLY HAVE SCHEDULED REPAIR AFTER MULTIPLE ATTEMPTS TO PUSH THIS.

TL* THE CONTACT OWNS A 2014 TESLA MODEL S. THE CONTACT STATED THAT THE MONITOR FOR THE BACK-UP CAMERA WAS INOPERABLE. THE CONTACT TOOK THE VEHICLE THE DEALER TESLA (28721 CANWOOD STREET, BLDG-A, AGOURA HILLS, CA 91301, 816-540-4729 AND WAS INFORMED THAT THE MCUV1 MODULE WAS DEFECTIVE. THE HARDWARE WAS USED TO UPDATE THE SYSTEM BUT WAS INOPERABLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 70,000.

FAILURE OF TOUCHSCREEN. DASHBOARD DISPLAY AT -5 BRIGHTNESS, COULD NOT SEE THE INFORMATION. NO TURN SIGNALS AND NO REVERSE CAMERA. LOSS OF CONTROL TO AIR/HEATING, SUNROOF, MUSIC, GARAGE DOOR CONTROL. TESLA REMOTE DIAGNOSTICS TEAM DETERMINED THE MCU HAD AN INTERNAL FAULT AND WOULD NEED TO BE REPLACED.

THE TOUCHSCREEN WOULD BECOME LESS RESPONSIVE, THE POWER-UP TIME BECOMES LONGER, THE SCREEN WOULD FREEZE AND WOULD HAVE TO BE REBOOTED, OR EVEN TOTAL FAILURE OF THE MCU UNIT AND ONE DAY COMPLETE BLACKOUT OF SCREEN. THIS HAPPENS WHEN ITS STATIONARY AND DRIVING BOTH

MCU TOUCHSCREEN FAILED. VEHICLE WAS STATIONARY. TURN SIGNALS AND OTHER FUNCTIONS QUIT WORKING.

MY INFOTAINMENT (CENTER LCD PANEL) SHUT OFF WITHOUT WARNING AND COULD NOT BE RESTARTED WHILE DRIVING. THIS SUDDEN FAILURE TOOK MY ATTENTION AWAY FROM THE ROAD AND REPEATEDLY ATTEMPTING TO RESTART THE SCREEN WAS ALSO A HAZARD FORCING ME TO PULL TO THE SIDE OF THE ROAD BUT WAS STILL UNABLE TO RESTART THE INFOTAINMENT CENTER. WITH THE INFOTAINMENT SYSTEM DOWN, THE MAJORITY OF THE FEATURES IN THE VEHICLE ARE CUT OFF FROM ME. I LATER READ THAT THIS IS A COMMON PROBLEM AFFECTING TESLAS BUILT BETWEEN 2013 AND 2018.

TESLA MCU FAILING. NO REAR VIEW CAMERA. NO TURN SIGNALS AND ALL DISPLAY ITEMS ON THE CENTER SCREEN UNAVAILABLE INCLUDING CLIMATE CONTROL, WHEN THE MCU - MEDIA CONTROL UNIT FREEZES OR GOES BLACK. I WAS HAVING SYMPTOMS OF IMMINENT FAILURE AND I HAD THE EMMC CHIP REPLACED BY A 3D PARTY TO INSURE I WOULDN'T GET STUCK.

MY AUTOMOBILE HAS BECOME UNRESPONSIVE. WHEN I ATTEMPT TO START IT, THE MESSAGE "SYSTEMS ARE POWERING UP" APPEARS BUT NOTHING HAPPENS. THIS HAS HAPPENED ON SEVERAL OCCASIONS AND NOW 2 DAYS IN A ROW AND AM UNABLE TO DRIVE THE CAR AS IT DOES NOT ALLOW ME TO. I HAVE WAITED OVER 15 MINUTES WITH STILL NO RESPONSE. IT HAD REMAINED PARKED FOR 3 DAYS BEFORE TRYING TO OPERATE IT. I AM UNABLE TO RESET THE POWER ON THE CAR SINCE THE MEDIA CONTROL SCREEN STAYS BLACK. THE TESLA APP WILL NOT CONNECT TO THE CAR. THE WINDOWS, LIGHTS, DOOR LOCKS STILL OPERATE, BUT I AM UNABLE TO SHIFT THE CAR INTO DRIVE TO GET TO A SERVICE CENTER. I AM TOLD IT WILL BE $195 TO DIAGNOSE. I HAVE 102,132 MILES. THE ISSUES STARTED OCCURRING APPROXIMATELY 50K MILES AFTER I PURCHASED IT. IN FEBRUARY OF THIS YEAR, I REPLACED...

TOTAL MAIN COMPUTER FAILURE (MCU) - MANY SAFETY FEATURES WERE UNACCESSIBLE AND NOT AVAILABLE INCLUDING BUT NOT LIMITED TO TURN SIGNALS AND HAZARD LIGHTS STOP WORKING, THE SETTINGS FOR AUTOPILOT AND DRIVING ARE GONE, THE SUSPENSION SETTINGS, THE ABILITY TO TURN ON HEADLIGHTS MANUALLY, ABILITY TO MANUALLY LOCK AND UNLOCK THE VEHICLE, NAVIGATION, A/C, SUNROOF CONTROLS, ETC.

MS1 BROKEN, NEEDED TO REPLACE

MEDIA CONTROL UNIT(MCU) FAILED DUE TO DESIGN FLAW OF MEMORY BEING OVERWRITTEN UNTIL IT HITS A LIMIT. ONCE THE LIMIT IS HIT, THE MCU NO LONGER WORKS. THE MCU CONTROLS THE BACK UP CAMERA AND TURN SIGNALS. BOTH NO LONGER WORK AND I AM NOT ABLE TO VIEW THE BACK UP CAMERA OR SIGNAL LANE CHANGES OR TURNS WHILE DRIVING.

MEDIA CONTROL UNIT MCU FAILURE. NO AEB (ADVANCED EMERGENCY BRAKING) NO CONTROLLING SUSPENSION HEIGHT NO MANUAL CONTROL OF HEADLIGHT LIGHTS NO BLINKER SOUNDS STEERING MODE DEFAULTS TO SOME SETTING (E.G. IF I HAVE IT SET TO SPORT, DURING REBOOT OF MCU IS CHANGES TO STANDARD OR COMFORT, NOT SURE BUT I CAN FEEL THE STEERING WHEEL TAKE LESS EFFORT TO TURN THAN MY NORMAL SPORT MODE) NO HVAC (HEAT, COOL, VENT) NO DEFROSTERS NO SEAT HEATERS NO STEERING WHEEL HEATERS NO RADIO/STREAMING NO APP CONNECTIVITY TO CONTROL THE CAR NO ABILITY TO SEE THE CAR CHARGE STATUS FROM APP

DROVE OUT OF TOWN AND PARKED THE VEHICLE IN DRIVEWAY FOR ABOUT 5 HOURS, WHEN I RETUNED TO DRIVE IT BACK (10 PM) CENTER TOUCH SCREEN WAS BLANK. I NOTICED THAT THERE WAS LOSS OF FUNCTION OF NEARLY EVERYTHING IN THE VEHICLE. I COULD STILL DRIVE IT BUT WITH ABILITY TO USE TURN SIGNAL LIGHTS, OR HEADLIGHTS (VERY DANGEROUS DRIVE AT NIGHT). STEERING WHEEL BUTTONS, AC, AUDIO, PHONE BLUETOOTH, AND ALL CONTROLS OF THE VEHICLE WERE COMPLETELY LOST. IT WAS 90 DEGREES OUTSIDE THAT NIGHT AND HAD TO DRIVE WITHOUT AC, I COULD NOT MAKE OR RECEIVE PHONE CALLS DUE TO BLACK SCREEN, SUN ROOF COULD NOT BE OPENED. BASICALLY THE VEHICLE BECAME A BARE BASIC VEHICLE WITHOUT ANY OF THE SAFETY FEATURES OR EVEN THE BASIC FEATURE SUCH AS SIGNAL LIGHTS. I AM NOT SURE IF THERE WAS AN EMERGENCY IF AIRBAGS WOULD HAVE RESPONDED EITHER! THE CAR FELT...

SCREEN BLACKED OUT AND I LOST SIGNALS AND CONTROL

I WAS DRIVING ON THE HIGHWAY, AND SUDDENLY THE MAIN SCREEN GOES BLACK, AND THE TURN SIGNALS STOP WORKING AND I HAD TO USE HAND SIGNALS ( MOST OF THE PPL DIDN'T UNDERSTAND THEM) AND THE AC SYSTEM TURNED OFF ( I WAS DRIVING WITH THE KIDS IN THE CAR AND UNTIL GOT HOME THEY WERE DEHYDRATED, AS IT WAS OVER 100 DEGREES OUTSIDE)

MY TESLA S HAS YET ANOTHER DEFECTIVE MCU CONSOLE RUINED BY EXCESSIVE DATA COMMUNICATION BY TESLA.. IT IS DANGEROUS TO DRIVE BECAUSE THE CAR SPEED IS EXTREMELY FAINT IN THE INSTRUMENT WINDOW, AND THERE IS NO SOUND WHEN THE TURN SIGNAL IS ACTIVATED, NO RADIO, NO MAP, AND NO HVAC CONTROL. I HAVE TO PAY TESLA $1553.TO REPLACE IT WITH A REMANUFACTURED UNIT - SOME OTHER OWNER'S EX-MCU? TESLA PROMOTES THIS AS A "SMART CAR." WITHOUT THE MCU CONSOLE, IT S A DUMB CAR.

MCU 1 FAILURE IN AN OLDER MODEL S. TESLA RECOGNIZED THE ISSUE AND IS NOW INSTALLING A BETTER MCU. HOWEVER, WARRANTY REPAIRS ARE BEING DONE WITH REFURBISHED MCU 1 COMPONENTS.

THE VIDEO SCRREN (MCU) GOES BLANK WHILE DRIVING AND NAVIGATING AND BACKING UP. WHILE BACKING INTO MY GARAGE TGE SCREEN WENT BLANK CAUSING DANGEROUS SITUATION NOT SEEING WHAT WAS BEHIND ME. WHILE NAVIGATING THE SCREEN WENT BLANK CAUSING ME TO MISS AN EXIT ON THE FREEWAY.

TL* THE CONTACT OWNS A 2014 TESLA MODEL S. THE CONTACT STATED THE WHILE OPERATING THE VEHICLE THE CENTER TOUCH SCREEN DISPLAY WAS INOPERABLE AND WOULD NOT ILLUMINATE. DUE TO THE DISPLAY FAILURE THE REAR VIEW CAMERA, TURN SIGNAL LIGHTS AND HIGH BEAM LIGHTS WOULD NOT ACTIVATE. ALSO WHILE CHARGING, THE BATTERY WOULD OVER HEAT AND THE ODOR OF BURNING PLASTIC WAS PRESENT. THE VEHICLE WAS TAKEN TO THE LOCAL TESLA SERVICE CENTER LOCATED AT 210 ANDOVER ST. PEABODY MA.WHO REPROGRAMMED THE SYSTEM BUT THE FAILURES CONTINUED TO OCCUR. THE CONTACT WAS INFORMED THAT THE DISPLAY SYSTEM NEEDED TO BE REPLACED BUT THE PARTS WERE NOT AVAILABLE. THE FAILURE MILEAGE WAS 160,000.

WHEN STARTING MY VEHICLE, THE VEHICLE'S CENTER CONSOLE SCREEN DID NOT POWER ON. THE INSTRUMENT CLUSTER (BEHIND STEERING WHEEL) DID POWER ON, BUT THE VEHICLE WAS VERY SLOW (ABOUT 2 MINUTES) BEFORE IT COULD BE PUT INTO "DRIVE" (THE INSTRUMENT CLUSTER SAID THAT VEHICLE WAS POWERING UP). I THEN ATTEMPTED TO RESTART THE CENTER CONSOLE SCREEN (MCU) MANUALLY (BY PRESSING BOTH BUTTONS ON STEERING WHEEL FOR 20 SECONDS), BUT NOTHING HAPPENED. I BEGAN DRIVING, AND NOTICED SEVERAL FUNCTIONS WERE NOT WORKING: WHEN INDICATING TURN SIGNALS, THERE WAS NO SOUND, AND USING A LARGE GLASS WINDOW TO VERIFY, THE EXTERIOR TURN SIGNALS WERE NOT LIGHTING UP. THE REAR VIEW CAMERA AND PARKING SENSORS WOULD NOT ACTIVATE WHEN CAR WAS IN "REVERSE" GEAR. HEADLIGHTS WOULD TURN ON AUTOMATICALLY WHEN IT WAS DARK, BUT I HAD NO DAYTIME RUNNING LIGHTS (ALSO VERIFIED WITH GLASS WINDOW). I COULD ALSO NOT MANUALLY TURN HEADLIGHTS /...

MY TESLA P85D YEAR 2014 HAD THE CENTER CONSOLE THAT CONTROLS ALL THE NAVIGATION, HEATING, A/C, SEAT ADJUSTMENTS, MUSIC, CHARGING, HAS GONE BAD AND A LOT OF THE BLOGS I READ STATE THIS IS DUE TO A FAULTY FLASH MEMORY WITH THE MULTIMEDIA CONTROL UNIT (MCU). THE CAR IS DRIVEABLE BUT TOO MANY FEATURES THAT YOU DEPEND ON TO DRIVE ARE NOT OPERABLE DUE TO THE MEDIA CONSOLE NOT BEING USABLE. THE MEDIA CONSOLE IS JUST BLACK AND NOT ABLE TO BE TURNED ON.

THE MCU (LARGE TOUCH SCREEN CONTROL PANEL) HAS BEEN REBOOTING RANDOMLY FOR YEARS WHILE DRIVING RENDERIMG SOME CAR FUNCTIONS NON FUNCTIONAL INCLUDING TURN SIGNAL. TODAY IT TURNED OFF COMPLETELY LEAVING THE CAR DRIVABLE BUT HANDICAPPED AND I AM UNSURE IF IT SAFE TO DRIVE. I UNDERSTAND TESLA KNOWS ABOUT THE EMMC FAILURE THAT CAN CAUSE THIS ISSUE YET THEY DON'T WARN CUSTOMERS ABOUT THIS POTENTIAL ISSUE ESPECIALLY WHEN UNDER WARRANTY AND WHEN IT COULD CAUSE DANGEROUS DRIVING CONDITIONS. THE LEAST TESLA COULD DO IS TELL CUSTOMERS ABOUT WHAT DANGERS MAY BE PRESENT AND THAT SOME LEGAL BASED FUNCTIONS OF THE VEHICLE LIKE THE TURN SIGNALS WILL BE INOPERABLE. IT'S UPSETTING THAT TESLA KNOWS ABOUT THESE ISSUES AND IS NOT INFORMING CUSTOMERS.

ON MAY 19TH, I ATTEMPTED TO START THE CAR BUT FOUND THAT THE MAIN CENTRAL TOUCHSCREEN WOULD NOT TURN ON. MULTIPLE ATTEMPTS TO START, INCLUDING ALL AVAILABLE REBOOT OPTIONS AS INSTRUCTED BY TESLA TECH SUPPORT VIA PHONE FAILED TO RESTART THE SCREEN. BECAUSE SERVICE HAD TO BE PERFORMED AT THE DEALERSHIP IN ATLANTA, I WAS FORCED TO DRIVE THE VEHICLE WITHOUT THE TOUCHSCREEN. WHILE BASIC FUNCTIONS WERE AVAILABLE, THE LOSS OF THE TOUCHSCREEN CREATED A SIGNIFICANT SAFETY ISSUE. I HAD TO DRIVE ROUGHLY 75 MILES ON THE INTERSTATE DURING A HEAVY RAINSTORM. THE LOSS OF TOUCHSCREEN MEANT I HAD NO CLIMATE CONTROL--NO A/C OR DEFROST FUNCTIONS--SO VISIBILITY WAS GREATLY IMPAIRED AND I WAS REDUCED TO PERIODICALLY (AND DANGEROUSLY) WIPING THE WINDSHIELD WITH A TOWEL TO MAINTAIN VISIBILITY. THERE WERE MULTIPLE OTHER IMPACTS, INCLUDING LOSS OF ALL AUDIO AND BLUETOOTH, NAVIGATION, AND I WOULD WORRY THAT SOME OF THE ELECTRONIC SAFETY...

THE MCU UNIT - MEDIA CONTROL UNIT - IS FAILING. SIGNAL LIGHT INDICATOR DOES NOT MAKE A SOUND, THE WARNING SOUNDS FOR BEING TOO CLOSE TO AN OBJECT ARE GONE. OTHER WARNING BEEPS, CHIMES, BELLS, ETC. ARE GONE. SOME INDICATORS ON THE DISPLAY SCREEN ARE INOPERABLE. THE TOUCH SCREEN DOES NOT RESPOND TO TOUCH FOR SOME FEATURES/CONTROLS. ALL OF THE CAR'S CONTROLS ARE ON THE TOUCH SCREEN. MY CAR IS ONLY 6 YEARS OLD. IT IS SOLID STATE CIRCUITRY. HOW CAN IT FAIL ? MY WARRANTY HAD JUST EXPIRED. OF COURSE. THIS IS AN ELECTRONICS PROBLEM OF A KEY COMPONENT OF THE VEHICLE. I DON'T KNOW IF IT IS DUE TO POOR DESIGN OR DEFECTIVE COMPONENTS BUT IT IS A SERIOUS ENOUGH PROBLEM THAT I FELT I SHOULD REPORT IT.

MY MCU JUST WENT BLACK AND NEVER CAME BACK ON. IT HAS BEEN LIKE THIS FOR 5 DAYS. I AM UNABLE TO CHARGE THE CAR, AND NO CLIMATE CONTROLS, AND ALSO NO REAR VIEW CAMERA. I HAVE A SERVICE APPOINTMENT IN 2 WEEKS, AND THEY REFUSE TO UPGRADED THE MCU1 TO AN MCU2 WHICH WILL HAVE LESS CHANGE OF HAVING THIS FAILURE IN THE FUTURE.

SEE NHTSA ACTION # 20010. MEDIA CONTROL UNIT FAILED 7/8/2020 @ 5:04 PM WHEN RETURNING TO THE CAR AFTER A BRIEF STOP, IN A PARKING LOT. CAR TOOK SEVERAL MINUTES TO "REBOOT" TO DRIVABILITY, BUT CENTER SCREEN IS STILL DOWN. BACKUP CAMERA AND BLINKERS (INSIDE OR OUTSIDE, CONFIRMED) ARE NOT WORKING. ADDITIONAL ITEMS DOWN INCLUDE DEFROSTERS, AUTO TILT MIRRORS FOR REVERSING, SEAT HEATERS ARE STUCK ON (FROM WHEN I HAD LAST USED THEM), SUNROOF WON'T OPEN (IT IGNORES STEERING WHEEL CONTROLS). BRAKE LIGHTS ARE STILL FUNCTIONAL, SO I DROVE IT HOME. CALLED TESLA AND WAS TOLD THAT THE REPLACEMENT MODULE IS OUT OF STOCK AND IS NOT EXPECTED FOR MANY WEEKS. IN THE MEANTIME, THE CAR IS UNDRIVABLE.

MAIN SCREEN TURNS OFF. THE 17" CENTER SCREEN FREEZES AND THEN TURNS OFF NOT LETTING USE REST CAMERA, DOOR UNLOCK, AND HVAC.

MEDIA CONTROL UNIT THAT CONTROLS THE CAR STOPPED FUNCTIONING ALTOGETHER. CAR WAS NOT OPERATIONAL.

THE CONTROL TOUCHSCREEN IN MY 2014 TESLA MODEL S KEPT REBOOTING ITSELF FOR NO APPARENT REASONS. SOMETIMES, IT DID THAT WHILE I WAS DRIVING AND I DIDN'T KNOW WHAT HAPPENED. THE SCREEN WENT DARK (BLANK) FOR SEVERAL MINUTES AND I LOST ACCESS CONTROL TO THE CAR. THOSE CONTROL FEATURES CAN ONLY BE ACCESSED THROUGH THE TOUCHSCREEN. IT HAPPENED QUITE A FEW TIMES WHILE MY WIFE WAS DRIVING AND SHE WAS EXTREMELY SCARED TO CONTINUE DRIVING. BOTH SHE AND I HAD TO SAFELY PULL TO THE SIDE OF THE ROAD/HIGHWAY AND WAITED UNTIL THE SCREEN CAME BACK. WE'RE AFRAID THAT ONE OF THESE DAYS, WE WILL LOSE FULL CONTROL OF THE CAR WHICH MAY IN TURN CAUSE AN ACCIDENT. *TR

MCU FAILED AND I WAS NOT ABLE TO DRIVE MY CAR. IF I WAS TO DRIVE NO TURN SIGNALS WERE ACTIVE AND YOUR UNABLE TO CHARGE.TESLA CHARGED ME 1500 DOLLARS FOR A REPLACEMENT. *TR

SCREENS GO BLANK AT TIMES AND IN THE MIDDLE OF DRIVING. SCREEN IN PICTURE IS DELAMINATING. THIS HAPPENS MULTIPLE TIMES, NOT JUST A SINGLE OCCURRENCE.

WHILE PARKED WITH THE SUNROOF OPEN, WHEN I WENT TO RE-ENTER THE VEHICLE, THE MAIN SCREEN (MCU) REMAINED BLANK AND NEVER CAME BACK TO LIFE. WHILE DRIVING HOME, I WAS UNABLE TO USE TURN SIGNALS, ADJUST BASICALLY ANY DRIVING ITEMS INCLUDING SUSPENSION, DRIVE MODE, STEERING CONTROLS, HVAC, LIGHTS, OR CLOSE THE SUNROOF. THE CAR WAS TECHNICALLY ABLE TO BE DRIVEN, BUT I ALSO HAD NO LIGHT CONTROL, NO BACK UP CAMERA, AND IT COULD ONLY CHARGE AT A BASICALLY UNUSABLE SPEED. TESLA'S ONLY FIX WAS TO REPLACE THE ENTIRE MCU UNIT.

CENTER DISPLAY WENT BLACK. CAR WAS STATIONARY. NO AC, NO BACK UP CAMERA,NO BLINKERS ETC.

THE MEDIA CONTROL UNIT (MCU) FAILED ON MY TESLA IN JANUARY 2020. THE MCU CONTROLS SAFETY FEATURES SUCH AS FRONT AND REAR DEFROST, HAZARD LIGHTS, HEADLIGHTS, TURN SIGNALS AND CHARGING FOR THE MAIN BATTERY. THE EMMC CHIP FAILED WHEN THE VEHICLE WAS PARKED. THE FAILURE CAUSED THE VEHICLE TO BE INOPERABLE.

MCU UNIT HAS A DESIGN FLY WHERE IT WILL BE INOPERABLE CAUSING A SAFETY ISSUE. *TR

MCU THE MAIN DISPLAY IS SLOW TO RESPOND AND INTERNET ACCESS DOES NOT WORK AS IT SHOULD. SCREEN BLINKS/TURNS OFF RANDOMLY. *TR

VEHICLE'S MCU GOES BLACK AND REBOOTS WHEN IN FLIGHT. LOSS OF ABILITY TO CONTROL KEY VEHICLE FEATURES.

WHILE STATIONARY, JUST AFTER GETTING INTO THE CAR WHICH IN THIS CAR IS HOW IT TURNS ON, MCU IS FAILING DUE TO EXCESSIVE LOGGING ISSUE. MAIN SCREEN GOES BLACK RANDOMLY. LOSE CONTROL OF MAJOR FUNCTIONS OF CAR, INCLUDING AC.

THE MCU STOPPED WORKING, I'M LEAD TO BELIEVE BASED ON FORUMS I'VE READ ON, THIS IS DUE TO THE EMMC FAILING DUE TO TESLA HAVING A DESIGN FLAW AND ALSO HAVING EXCESSIVE AMOUNT OF UNNECESSARY LOGGING TO THE CHIP. *TR

THE MAIN SCREEN ON MY 2014 TESLA S RECENTLY WENT OUT AND SOME RESEARCH ONLINE SHOWS THAT MANY OTHERS EXPERIENCED THE SAME ISSUES. TESLA SENT A TECHNICIAN AND SAID IT IS THE MCU (MEDIA CONTROL UNIT) CHIP THAT WENT BAD AND A REPLACEMENT WILL COST $1,500+ THE TESLA TECHNICIAN SAID THE CAR IS DRIVABLE BUT THE BLINKERS DO NOT WORK, ALONG WITH THE BACK UP CAMERA AND PARKING SENSORS. HE STATED THOSE THINGS ARE INTEGRATED WITH THE MAIN MCU UNIT AND WHEN THE MCU GOES OUT, THOSE THINGS WILL NOT FUNCTION. I AM CONCERNED ABOUT DRIVING MY VEHICLE WITHOUT THE FUNCTION OF THE BLINKERS AS IT COULD PRESENT A HAZARD. THERE HAS BEEN REPORTS SIMILAR TO MINE WHERE TESLA ADDED A FINITE MEMORY CHIP TO THE MCU SYSTEM THAT DETERIORATE AND WILL FAIL AFTER A LENGTH OF TIME AND BECAUSE TESLA UPDATE THE SOFTWARE IN THE CAR VERY FREQUENTLY, THE...

MCU 17" BLACK SCREEN. CAUSED ISSUE WHERE CAR WOULD NOT CHARGE ABOVE .5KW ADDITIONALLY BACKUP CAMERA NO LONGER WORKED. I HAD A 3RD PARTY REPAIR THE FAILED EMMC WHICH RESOLVED THE PROBLEM. THIS HOWEVER IS A MUCH LARGER ISSUE. HTTPS://TESLAMOTORSCLUB.COM/TMC/THREADS/CONSOLIDATED-EMMC-THREAD-MCU-REPAIR-BLACK-CENTER-SCREEN.181124/ HTTPS://TESLAMOTORSCLUB.COM/TMC/THREADS/FEDS-INVESTIGATE-FAILING-MCUS.197384/. *TR

MY EMMC CHIP FAILED IN MCU WHEN VEHICLE WAS FIVE YEARS OLD WITH LESS THAN SIXTY THOUSANDS MILES. NO REAR VIEW CAMERA, NO ACCESSORIES ARE WORKING, NO AC, TOUCH SCREEN WENT BLACK. WITH 'PIN TO DRIVE' ACTIVATED CAR BECOMES A BRICK: YOU CAN'T ENTER PIN BECAUSE SCREEN DOESN'T WORK - CAN'T START/DRIVE. REPLACEMENT WITH REMANUFACTURED UNIT (NOT EVEN NEW) COST $2000!!! *TR

VEHICLES MCU (MIDDLE CONTROL UNIT) STOPPED WORKING. BLINKERS WOULD NOT WORK, SO I WAS UNABLE TO SIGNAL WHILE DRIVING. THE REARVIEW CAMERA STOPPED WORKING AS WELL AND THE AC SYSTEM WAS STUCK ON. *TR

I WENT TO TURN ON MY CAR IN THE MORNING AND THE MCU WAS SHOWING A CHECKER PATTERN OF ERRORS. AS I DROVE THE GPS DID NOT UPDATE MY LOCATION. WHEN I GOT BACK IN THE CAR THE MCU WAS COMPLETELY DEAD BLACK. THE CAR HAS ALREADY HAD THE MCU REPLACED ONCE IN 2017, 3 YEARS AFTER DELIVERY FROM TESLA. 3 YEARS LATER IT DIED AGAIN AND I'M HAVING TO REPLACE IT OUT OF WARRANTY FROM TESLA. THE BILL IS EXPECTED TO BE $2000 AND THE CAR IS SUPPOSED TO BE IN THE SERVICE CENTER FOR OVER A WEEK. *TR

WHEN I WENT TO START THE CAR THE CENTRAL TOUCHSCREEN FAILED. COULD NOT CONTROL THE LIGHTS, A/C, HEATING, COULD NOT RECHARGE THE CAR. TESLA CHARGED ME OUT OF WARRANTY OVER $2000 TO REPLACE THE TOUCHSCREEN WITH A REFURBISHED ONE. THEY REFUSED TO GIVE THE OLD PART TO ME EVEN THOUGH THIS WAS REPLACED IN NEVADA WHERE THE LAW STATES THAT THEY HAVE TO GIVE THE OLD PARTS BACK TO THE OWNER. I HAD TO PAY THEM ANOTHER $1000 TO GET THE PART BACK AS IT CONTAINED SO MUCH PRIVATE INFORMATION. *TR

DUE TO RECENT NEWS THIS WEEK OF NHTSA INVESTIGATING THE TESLA MODEL S FROM 2012 TO 2015 REGARDING THE FAULTY SCREEN, I WANTED TO REPORT THAT I HAD A SIMILAR PROBLEM. THE LARGE SCREEN CALLED MCU OR MEDIA CONTROLLED UNIT ON MY MODEL S WOULD HAVE PROBLEMS OF BLACKING OUT WHILE DRIVING OR WHEN TRYING TO START FROM A PARKED POSITION. ULTIMATELY, IT SHUT DOWN ALTOGETHER. I HAD REPORTED THE PROBLEM TO TESLA WHEN THE SCREEN BLACKOUT PROBLEMS WERE HAPPENING IN 2018 AND 2019 BY CALLING CUSTOMER SERVICE. TESLA'S CUSTOMER SERVICE TOLD ME TO REBOOT THE SYSTEM BY HOLDING DOWN THE TWO SCROLL BUTTONS. AFTER MULTIPLE REBOOTS OVER A PERIOD OF 6+ MONTHS, THE SCREEN BLACKED OUT PERMANENTLY, AND THE REBOOT SOLUTION NO LONGER WORKED. I HAD TO GET THE PROBLEM FIXED AT A COST OF $2,614.50. *TR

TOUCHSCREEN WAS UNRESPONSIVE AND NEEDED TO BE REPAIRED. VEHICLE WAS STATIONARY. *TR

TL* THE CONTACT OWNS A 2014 TESLA MODEL S. THE CONTACT STATED THAT AT START-UP, THE DISPLAY FAILED TO ILLUMINATE. THE VEHICLE WAS TAKEN TO TESLA (5544 OKEECHOBEE BLVD, WEST PALM BEACH, FL 33417) TO BE DIAGNOSED HOWEVER, THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT STATED THAT AS A COURTESY, THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT REACHABLE. THE FAILURE MILEAGE WAS APPROXIMATELY 1,300.

THE TOUCH SCREEN WENT BLANK IN LATE APRIL OR EARLY MAY, AND I COULD NOT REJUVENATE IT WITH A REBOOT OR OTHER TECHNIQUES. THE BACKUP CAMERA AND OTHER CRITICAL FEATURES AND CONTROLS WERE NOT FUNCTIONAL AS A RESULT. I TOOK THE CAR TO TESLA AND THEY REPLACED THE MEDIA CONTROL UNIT (MCU). I AM ATTACHING THE ESTIMATE WHICH INDICATES THE REPAIR AND COST FOR THAT REPAIR. AT THIS POINT, THE MCU REPLACEMENT SEEMS TO HAVE SOLVED THE ISSUE. *TR

MY CAR EXPERIENCED THE ISSUES DESCRIBED IN NHTSA ACTION NUMBER PE20010 WITH A PREMATURE MCU FAILURE DUE TO THE EMMC CARD FAILING. THIS EMMC CARD HAS BEEN FOUND TO FAIL TOO QUICKLY DUE TO TESLA ALLOWING DEBUG LOGGING TO THE EMMC CARD THAT IS NOT NEEDED FOR NORMAL VEHICLE USERS. THIS EXCESS LOGGING WAS CONFIRMED BY ELON MUSK ON OCTOBER 12 2019 HTTPS://TWITTER.COM/WK057/STATUS/1211704973970550785. THIS EXPENSIVE FIX AFTER FAILURE HAD TO BE REPAIRED OUT OF WARRANTY FOR A LARGE COST. THIS FAILURE CAUSES THE REAR VIEW CAMERA TO FAIL TO WORK, THE CLIMATE CONTROL TO FAIL TO WORK MEANING THAT DEFROSTING DOES NOT WORK CAUSING POTENTIAL VEHICLE ISSUES, AND POTENTIAL SLOW CHARGING OF THE CAR. THE CAR ALSO TAKES ABOUT 30 SECONDS TO A MINUTE TO GET OUT OF PARK WHILE THE VEHICLE SUBSYSTEMS "FAIL" THE MCU ALSO CAUSING A SAFETY ISSUE IF THE DRIVER NEEDS TO GET OUT OF A...
