What 379 owners told NHTSA about the 2017 Tesla Model S 75d

MCU STILL FAILING AFTER HAVING IT REPLACED.

NHTSA ODI 11374990

THE MCU TOUCHSCREEN IS REQUIRING REBOOTING ON AN INCREASING BASIS, 4 OR 5 TIMES A WEEK. THE REBOOTING CAN TAKE AT LEAST 5 MINUTES. I FEEL IT IS A SAFETY PROBLEM SINCE THE VEHICLE IS NON-OPERATIONAL DURING THIS TIME.

NHTSA ODI 11375013

2017 TESLA MODEL S. CENTER SCREEN FREEZES UP AND DASH LIGHTS GO BRIGHT TO DARK. ISSUE; WHEN CENTER SCREEN LOCKS UP YOU CAN'T USE THE FOLLOWING- DEFROSTERS, AIR CONDITIONING, HEATER, GARAGE DOOR REMOTE, NAVIGATION, BACK UP CAMERA, AUTO POILET WARNING GOES ON AND OFF WITH OUT ME TOUCHING IT.. VERY DANGEROUS AND SCARY . I HAD IT IN TWICE FOR THE SAME PROBLEM AND WAS TOLD IT WAS A SIMPLE SOFT WEAR UPDATE. FINALLY HAVE AN APPOINTMENT BUT IT TOOK OVER TWO WEEKS. NOW I AM TOLD THAT IF THERE WAS AN UPGRADE I NEED TOO PAY OUT OF POCKET FOR THE COMPANIES FAULTY ISSUES. SERIOUSLY! THIS HAPPENS MOVING AND STATIONARY. HAPPENS MULTIPLE TIMES WEEKLY

NHTSA ODI 11375077

THE MCU TOUCHSCREEN FAILS CONSTANTLY CAUSING NO ACCESS TO REAR VIEW CAMERA, AC CONTROLS, NAVIGATION, AND LOSS OF PRESET SETTINGS FOR MIRRORS AND DRIVE SEAT POSITION. REBOOT TAKES OVER 5 MINS WHILE CAR IS IN OPERATION TO NO AC WORKING. BOTH HEADLIGHTS HAVE BEEN REPLACED OVER 10 TIMES DUE TO BURNED OUT DAYTIME RUNNING LIGHTS. I HAVE PAID FOR THE LAST REPLACEMENT ONLY FOR IT TO FAIL AGAIN.

CENTRAL SCREEN (MEDIA CONTROL UNIT - MCU) CONTINUES TO SHUT DOWN AND RESTART WHICH CAUSES LOSS OF AIR BAG, CLIMATE (INCLUDING DE-FOGGING), REAR CAMERA AS WELL AS MEDIA CONTROLS/GPS. TESLA REPAIR INDICATES THAT IT IS A DEFECT THAT CAN ONLY BE FIXED BY UPGRADING TO THEIR NEW MCU2 AT A LARGE COST. REPLACING WITH SAME SYSTEM WILL NOT FIX ISSUE. THIS RESTARTING/REBOOTING OCCURS WHEN DRIVING AND WHEN IDLE WITH NO WARNING. TESLA CLAIMS IT DOES NOT AFFECT DRIVING BUT IT COMPLETELY SHUTS DOWN ABILITY TO CHARGE, USE CLIMATE CONTROL(INCLUDING WINDOW CLEARING) AND SAFETY CONTROLS LIKE AIRBAGS. THIS HAPPENS APPROXIMATELY 1X DAILY WHEN DRIVING CAR STARTING AFTER TESLA INSTALLED SOMETHING RELATED TO FULL SELF DRIVING OPTION.

APPARENTLY A TOTAL FAILURE OF THE 'DAUGHTER BOARD'. IN THIS INSTANCE THE CAR WAS PARKED WHEN IT HAPPENED. GOT INTO CAR AND AT FIRST WOULDN'T POWER UP AS NORMAL. TOUCHSCREEN, INCLUDING ALL CONTROLS FOR VEHICLE, WOULD NOT START UP. CLIMATE STARTED UP BUT COULD NOT BE CONTROLLED. CAR WOULD START BUT BLINKERS DIDN'T NOT WORK. SOMETHING SIMILAR HAS HAPPENED ON PERHAPS 10 OR MORE OCCASIONS IN THE PAST, THOUGH USUALLY COULD BE FIXED WITH A HARD RESET. IN AT LEAST 2 INSTANCES THE AC HAS STOPPED WORKING MIDWAY THROUGH A DRIVE (THROUGH OVER 100 DEGREE WEATHER WITH ELDERLY PERSONS IN A VERY LONG DRIVE- VERY UNSAFE)

COMMON COMPLAINTS REGARDING MAIN COMPUTER. TAKES LONGER EVERY DAY TO START, MANY DELAYS WITH EVERYDAY FUNCTIONS, BLACKOUT/RESTART DURING OPERATION, ETC...

NHTSA ODI 11361934

MEDIA CONTROL UNIT(MCU) FAILS. CAR HAS NO AUDIO(RADIO OR NAVIGATION), AND CAMERAS MALFUNCTION. SCREEN REFRESH EXTREMELY SLOW. ALL CAUSING SAFETY ISSUES AND DISTRACTIONS TO THE DRIVER. A RESET TEMPORARILY FIXES, BUT RESETTING EVERY TIME I GET IN THE CAR IS IMPRACTICAL. TESLA SERVICE REQUESTED I REMAIN PATIENT UNTIL A FIRMWARE MODIFICATION IS PREPARED. THEY DID NOT OFFER A TIMELINE. I UNDERSTAND THE MCU FAILURE IS COMMON AND CURRENTLY UNDER INVESTIGATION BY NHTSA

NHTSA ODI 11361938

MY 2017 MODEL S HAS HAD ISSUES WITH THE MCU WHEREBY THE CENTER SCREEN WOULD RESTART WHILE DRIVING. MANY OCCASIONS I WOULD BE BACKING OUT OF MY GARAGE AND CENTER SCREEN WOULD RESTART OR GO BLACK FOR EXTENDED TIME RESULTING IN NO BACK UP CAMERA OR TURN SIGNAL ACCESS. EARLIER THIS YEAR BEFORE COVID, I BACKED OUT OF MY GARAGE TO GO DROP OF MY KIDS AT SCHOOL. AND, THE CENTER SCREEN WAS BLACK FOR THE WHOLE TRIP - NO ACCESS TO BACK UP CAMERA, TURN SIGNALS, OR DEFROST CONTROLS.

TL* THE CONTACT OWNS A 2017 TESLA MODEL S. THE CONTACT STATED THAT THE HARDWARE COMPUTER FAILED. THE CONTACT STATED THAT THE VEHICLE WAS REPAIRED ONCE FOR THE FAILURE HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER TESLA SERVICE CENTER - LATHAM (326 OLD NISKAYUNA RD, LATHAM, NY 12110) HOWEVER, THE DEALER REFUSED TO SERVICE THE VEHICLE FOR FREE. THE CONTACT DROVE THE VEHICLE TO THE DEALER WITHOUT THE INDICATOR LIGHTS OR WINDSHIELD WIPERS OPERATIONAL. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT, OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 61,000.

THERE ARE CHALLENGES WITH THE MCU1 AND ITS INTEGRATION WITH FSD HARDWARE #3. THIS MANIFESTS AS FREEZES ON THE CENTRAL AND DRIVERS DISPLAYS UNTIL THE CARS MCU DOES A FULL RESTART(SPEEDOMETER IS NOT AFFECTED). THIS RESTART CAN TAKE AS LITTLE AS 5MIN OR CAN STAY OFF FOR THE DRIVE UNTIL MANUALLY FORCE REBOOT INITIATED. DURING THE FREEZE I EXPERIENCE LOSS OF PASSENGER AIRBAG(WARNING COMES ON, I CANT TELL IF OTHER AIRBAGS ARE AFFECTED). THE CLIMATE CONTROL SYSTEM TURNS OFF NO A/C OR HEAT IS AVAILABLE. SOMETIMES AUTO PILOT IS AFFECTED, SO I WOULD ASSUME EMERGENCY BRAKING IS AFFECTED BECAUSE ITS THE SAME SYSTEM AS AUTO PILOT. THE ODOMETER IS DOES NOT RECORD MILES IF THIS HAPPENS WHILE DRIVING. NO BACK UP CAMERA IS AVAILABLE. THESE ISSUES HAVE INCREASED SINCE I HAD THE HW3 UPGRADE HERE IS A WEBSITE THAT TALKS ABOUT THIS ISSUE HTTPS://TESLA-INFO.COM/BLOG/TESLA-MCU1-EMMC-FAILURE.PHP HTTPS://TESLAMOTORSCLUB.COM/TMC/THREADS/JOE-ROGAN-VS-MCU1-HW3.203776/

THE DEFECTIVE MCU WENT DOWN AND WHAT IS NOT BEING PROPERLY REPORTED, ESPECIALLY IN THIS PANDEMIC WORLD WE NOW LIVE IN, IS THAT BESIDES THE ENTERTAINMENT, THE AIR CONDITIONING (AND VIRAL HEPA FILTER), THE SUSPENSION HEIGHT, THE STEERING AND ACCELERATION PROPERTIES, NEARLY EVERYTHING IS NO LONGER ACCESSIBLE WHEN THE MCU FAILS BECAUSE TO THE DRIVER, THESE THINGS CAN ONLY BE ACCESSED AND MANIPULATED THROUGH THE CENTER CONSOLE, WHICH IS IN PERMANENT SHUT DOWN MODE. LOOK, I PERFORM FMEA ANALYSIS FOR A LIVING. THIS IS A SINGLE POINT FAILURE BEING CAUSED BY THE POOR DECISION TO SELECT AN MCU CHIP THAT HAS A LIMITED NUMBER OF DATA WRITES TO THE MEMORY, AND THAT CANNOT BE CLEARED OUT BY ANY SYSTEM DESIGNED INTO THE CAR. MINE JUST FAILED LAST WEEK AND MY CAR ONLY HAS 30,000 MILES ON IT. TESLA CLAIMS THAT THEY ONLY WARRANTY THE ENTERTAINMENT SYSTEM FOR 25,000 MILES. THE PROBLEM IS THAT THEY'VE INTEGRATED THE MCU AND EMMU AS THE SINGLE SOURCE OF OPERATIONS FOR ALL OTHER VITAL SYSTEMS IN THE VEHICLE. THIS IS COMPLETELY INSANE AND IS WITHOUT A DOUBT A SAFETY ISSUE, AS IT WAS 90 DEGREES THE DAY MY MCU FAILED AND DANGEROUSLY HOT INSIDE MY CAR, EVEN WITH ALL WINDOWS DOWN, WHICH ONLY GOT WORSE BECAUSE THERE IS SO MUCH THERMAL LOADS CREATED BY THE BATTERY, NORMALLY PROTECTED BY THE OVERHEAT SENSORS & FANS, THAT ARE NOW NOT OPERATING PROPERLY THANKS TO THE MCU FAILURE. IT ALSO IMPORTANT THAT YOU UNDERSTAND THE MOST OF THE NEED TO WRITE TO THE FINITE MCU & EMMU MEMORY IS CAUSED BY TESLA DURING THEIR FREQUENT SOFTWARE UPDATES. MINE IS A P100D LUDICROUS + AND COST WELL OVER $100,000 WHEN NEW. TELL ME WHAT OTHER MANUFACTURE WOULD BE ALLOWED TO GET AWAY WITH DESIGNING A SINGLE POINT OF FAILURE THAT EFFECTS NEARLY EVERY SYSTEM INCLUDING SAFETY FEATURES, AND THEN SAY ITS ONLY COVERED FOR LESS THEN THE TIME THEY KNOW THE FIRST FAILURE WILL OCCUR. CRIMINALS AND MAKE THEM ACCOUNTABLE NOW PLEASE.

MAIN COMPUTER EXPERIENCED THE EMMC FAILURE WHICH IS WIDESPREAD FOR THIS MODEL AND YEAR, AMONGST OTHERS. I COULD TELL IT WAS IMMINENT FOR FAILURE, HOWEVER WE DID NOT REALIZE THE VEHICLE NEEDS THIS COMPUTER FOR TURN SIGNAL CONTROL. THUS, MY WIFE DROVE HOME FROM WORK WITH A DEAD COMPUTER AND THOUGHT SHE HAS TURN SIGNALS WHEN SHE DID NOT. FORTUNATELY SHE MADE IT HOME SAFELY. WE HAVE NOT DRIVEN IT SINCE WE REALIZED THIS SAFETY CONCERN. FUFTHERMORE, THE BACKUP CAMERA ALSO IS UNUSABLE IN THIS STATE. I WENT AHEAD AND SCHEDULED FOR THE NEWER COMPUTER (WITHOUT THIS KNOWN ISSUE) TO BE INSTALLED AS SOON AS I SAW THE SYMPTOMS OF IMMINENT FAILURE, BUT IT DIED A COUPLE DAYS LATER, AND IS CURRENTLY NOT SAFELY DRIVABLE WHILE AWAITING THE PART.

MCU IS FAILING PREVENTING SAFETY FEATURES AND NORMAL FUNCTIONS SUCH AS TURN SIGNALS, AC, RADIO, NAV, ETC. HAPPENS WHILE DRIVING.

NHTSA ODI 11342282

COMPLETELY BLACK MCU SCREEN THAT DOES NOT TURN ON EVEN AFTER A REBOOT. NO AC, NO WARNING SOUNDS, AND MOST IMPORTANTLY NOT BEING ABLE TO USE TURN SIGNALS WHEN THE CAR IS BOTH STATIONARY AND MOVING.

NHTSA ODI 11339624

THE MAIN DISPLAY SCREEN FREEZES AND LOCKS UP WHICH REQUIRES ME TO PERFORM A RESET ON THE MAIN COMPUTER IN MY TESLA MODEL S.

NHTSA ODI 11338521

VEHICLE COMPUTER FAILS REPEATEDLY OVER AND OVER, HUNDREDS OF TIMES SINCE PURCHASING THE CAR AND TESLA REFUSES TO DO ANYTHING ABOUT IT. THE PRIMARY DISPLAY THAT INDICATES MY SPEED, INDICATORS ETC DOES NOT WORK AT INTERMITTENT TIMES, I AT OTHER TIMES CAN NOT CONTROL OR FUNCTION LIGHTS, TURN INDICATORS, OR BASIC FUNCTIONS OTHER THAN ACCELERATION AND BRAKING / TURNING. THIS HAS BEEN TO SERVICE MANY TIMES AND EACH TIME THEY SAY THEY WON'T DO ANYTHING TO HELP. OFTEN TIMES THE CRUISE CONTROL WON'T WORK, AND SINCE THE DISPLAY WON'T FUNCTION OR FREEZES COMPLETELY ' I CANNOT USE RADIO, NAVIGATION, ETC. THERE HAVE BEEN SEVERAL INSTANCES WHERE MY VEHICLE WILL NOT EVEN TURN ON, OR WILL TAKE 20 MINUTES TO 'BOOT' UP. THERE HAVE ALSO BEEN MAJOR ISSUES WHERE THE VEHICLE WILL NOT ACCEPT A CHARGE AT ALL. ADDITIONALLY, THE VEHICLE STATES A RANGE OF 299 MILES PER CHARGE, AND AFTER EXEMPLARY USAGE, I ONLY GET APPROX 265 MILES PER CHARGE NOW WHICH IS WELL BEYOND AVERAGE DEGRADATION FOR AN EV. *TR

MY CAR'S MCU (MEDIA CONTROL UNIT TOUCHSCREEN) IS NEAR DEATH AND 900 MILES FROM BEING OUT OF WARRANTY. THE SCREEN WENT BLACK ON ME FOR AN ENTIRE DAY BEFORE COMING BACK AND CONSTANTLY FREEZES AND NEEDS REBOOTS. DURING THIS TIME, I LOST ABILITY TO TURN ON AND OFF THE HEADLIGHTS, MUST RELY ON AUTO. LOST ABILITY TO CONTROL THE HVAC AND DEFROST. LOST ABILITY TO ADJUST AIR SUSPENSION. LOST ABILITY TO USE BACKUP CAMERA.

NHTSA ODI 11331659

MCU DOES NOT FUNCTION AS IT SHOULD ALL THE TIME. DASHBOARD GAUGES HAVE TURNED OFF WHILE VEHICLE WAS IN MOTION DISRUPTING NORMAL AND INTENDED OPERATION.

NHTSA ODI 11331574

THE MOBILE CONTROL UNIT (MCU) SCREEN WILL RANDOMLY REBOOT, SHUT DOWN, OR FREEZE. HAPPENS RANDOMLY AT ANY TIME, REGARDLESS IF THE VEHICLE IS STATIONARY OR MOVING. THIS IMPAIRS CRITICAL SAFETY FUNCTIONS SUCH AS DEFOGGER, BACKUP CAMERA, AND ALL OTHER ELECTRICAL CONTROLS (EX. HVAC).

NHTSA ODI 11331589

COMPUTER SCREEN HAS YELLOW BORDER. ALSO, SOMETIMES THE BACK UP CAMERA DOESN'T WORK, ESPECIALLY IF I BACK UP, STOP AND SHIFT TO NEUTRAL AND BACK UP AGAIN. I ALMOST ALWAYS HAVE TO PUT THE SHIFTER INTO D OR R TWO TO FOUR TIMES BEFORE IT ENGAGES COMING FROM NEUTRAL. THERE IS A CLUNKING NOISE WHEN I CROSS AN EXPANSION STRIP IN THE ROAD, OR A MINOR BUMP AT OVER 25-30 MPH. TESLA CAN'T FIND THE PROBLEM. I AM CONCERNED THAT IT MAY BE IN THE SUSPENSION. *TR

NHTSA ODI 11331153

MAIN CENTER SCREEN (REFERRED TO AS MCU1) QUIT WORKING AFTER I DROVE HOME FROM WORK ONE EVENING. THE CAR WAS STILL DRIVE-ABLE AND CHARGE-ABLE, BUT AUDIO/SAFETY CHIMES NO LONGER WORKED BECAUSE THOSE ARE POWERED BY THE MCU1 WHICH DIED. THE CAR WAS APPROXIMATELY 2.75 YEARS OLD WITH ABOUT 89,000 MILES ON ODOMETER WHEN THIS HAPPENED. IT WAS OUT OF WARRANTY TO FIX THIS ISSUE. *TR

NHTSA ODI 11330746

THE MCU IN MY CAR SIMPLY STOPPED WORKING. I COULD DRIVE IT BUT HAD NO SPEEDOMETER, NO SIGNALS, NOTHING THAT IS CRITICAL TO DRIVING SAFELY. IT WOULD NOT START CONSISTENTLY AND I WAS AFRAID IT WOULD STOP IN THE MIDDLE OF THE HIGHWAY ON MY WAY HOME. THE MCU IS THE CENTRAL COMPUTER IN THE CAR THAT CONTROLS EVERYTHING. *TR

NHTSA ODI 11330628

MY MAIN SCREEN WOULD COMPLETELY GO BLACK RANDOMLY AND WHEN THAT HAPPENS MY INSTRUMENT CLUSTER IN FRONT OF ME WOULD ALSO GO BLACK AND AS A RESULT I CAN'T SEE HOW FAST I'M GOING OR MY BLIND SPOTS OR ANYTHING REALLY. IT'S THE MCU THAT CONTINUES TO HAVE THIS PROBLEM AND TESLA WON'T REPLACE IT. *TR

I HAVE REACHED OUT TO TESLA 3 TIMES TO FIX A SUDDEN UNINTENDED ACCELERATION ISSUE. 11 DAYS AFTER I REPORTED THE ISSUE AND THEY TOLD ME MY CAR WAS OK TO DRIVE I GOT INTO A ACCIDENT. IT TOOK TESLA 5 MONTHS TO GIVE BACK THE REPORTS OF THE CRASH IN WHICH THEY SAID IT WAS MY FAULT. I HAVE LOST TRUST IN THE COMPANY AND HAVE SEEN THAT 127 OTHER PEOPLE HAVE BEEN AFFECTED BY THE SAME ISSUE ACCORDING TO CNN PLEASE TAKE CARE OF THIS ISSUE. ANY TESLA OWNER IS A PIONEER OF A FUTURE CREATION. AFTER THE ACCIDENT THEY TOLD ME AUTOPILOT IS ON BETA MODE ITS NOT PERFECT YET. THEY SHOULD NOT ALLOW PUBLIC TO USE A HAZARDOUS SOFTWARE. ALSO TESLA EMPLOYEES WERE VERY NEGLIGENT. I ALMOST DIED IN THIS ACCIDENT WITH MY FATHER AND THE MANAGER HAD NO IDEA OF MY CASE EVEN AFTER MY CAR WAS GIVEN TO ME AND THEY SAID IT WAS OK TO DRIVE. I GOT INTO A ACCIDENT 11 DAYS AFTER THEY OK'D MY CAR PLEASE HELP AS I AM FRUSTRATED AND DO NOT KNOW WHAT TO DO ANYMORE OR WHO TO GET TO FIX MY CAR. I HAVE DOCUMENTATION OF ADDRESSING SUDDEN INTENDED ACCELERATION TO TESLA MULTIPLE TIMES. THANK YOU
