What 417 owners told NHTSA about the 2016 Tesla Model X P90d

MCU (MEDIA CONTROL UNIT) FAILED ON MULTIPLE OCCASIONS, I WAS UNABLE TO CONTROL AC/RADIO/AUTOPILOT SYSTEM/ OR NAVIGATION. ALSO BOTH TURN SIGNAL WERE IN-OPERATIONAL. TESLA SERVICE CENTER REFUSES TO REPLACE THE MCU OR FIX IT. VEHICLE WAS IN MOTION, ON HIGHWAY AT A SPEED OF ABOUT 70 MPH.

THE CAR DOESN'T TAKE CHARGE. I DROVE MY CAR TO TRY DIFFERENT CHARGING SPOT IN THE SAME SUPERCHARGING STATION AND TRY IN ANOTHER CHARGING STATION. THE CAR DOESN'T CHARGE. IT WAS A WEEKEND WHEN THE CAR HAS CHARGING ISSUE. EVENTUALLY THE CAR JUST OUT OF JUICE. WON'T OPEN IT LET ME IN AND I HAVE TO TOW THE CAR TO SERVICE CENTER IN THE MONDAY SERVICE BUSINESS DAY. IT NEEDS SPECIAL TOWING WITH DOLLY. BECASUE OF THE CAR OUT OF JUICE THE 12V BATTERY IS DEAD TOO AFTER THAT. CHARGING PORT IS A KNOWN ISSUE TO TESLA BUT AFTER ALL THE REPAIR. I WAS CHARGED OF $1300

THE TOUCHSCREEN BECOME LESS RESPONSIVE THE PAST FEW MONTHS, THE POWER-UP TIME BECOMES LONGER, THE SCREEN WOULD FREEZE AND WOULD HAVE TO BE REBOOTED, AND ON JULY 24TH THE MCU UNIT IS A TOTAL FAILURE. I COULDN'T EVEN DRIVE THE CAR UNTIL TESLA MOBILE SERVICE COMES OUT TO CYCLE THE POWER OF 24V. THE COST IS $85 OF DIAGNOSTICS FEE BUT HE COULDN'T FIND ANYTHING BESIDES THAT IT IS NOT RESPONSIVE. AFTER THAT I HAVE TO RESCHEDULE ANOTHER VISITS WHICH IS NOT AVAILABLE UNTIL AUG 12TH. I CAN DRIVE NOW WITH BLACK MCU BUT I CAN'T CONTROL BLINKERS. MY BLINKERS ARE ALWAYS OFF. VERY UNSAFE. THIS CAR HAS ONLY 55K MILES. IT IS RIGHT AFTER THE WARRANTY EXPIRES. THE MOBILE SERVICE AND PHONE CALL WITH SERVICE SHOP IN RENO LOCATION BOTH SUGGEST ME TO REPLACE TO A NEW MCU AND SINCE IT IS OUT OF POCKET IT MAKES SENSE TO DO A MCU UPGRADE INSTEAD. TOTAL WITH PART $2500 IT WOULD BE AROUND $3000.

NHTSA ODI 11344047

THE MCU IS DEAD. CAR CANNOT BE OPERATED SAFELY. NO SIDE BLINKERS, NO HORN, NO AC. AT THIS POINT MY CAR CANNOT EVEN TURN ON AND CANNOT BE DRIVEN. CONTACTED TESLA, BUT IT IS NOT A SAFETY ISSUE AND THEY SENT ME HOME AS PARTS WERE OUT OF STOCK. IT IS NOT SAFE TO DRIVE AS BLINKERS DON'T WORK.

CENTER SCREEN (MCU) DIES/FREEZES UP WHILE DRIVING AND MUST TRY TO RESET ALL THE TIME. TESLA REFUSES TO ACCEPT RESPOSIBILITY AND REPLACE WITH NEW MCU UNDER WARRANTY.

NHTSA ODI 11343612

WHILE DRIVING THE CAR ON JULY 31 AT ABOUT 7PM, THE CENTER TOUCHSCREEN WENT BLACK AND WOULD NOT RESET USING TESLA INSTRUCTIONS. VEHICLE WAS PARKED. THE A/C AND CLIMATE CONTROLS WERE THEREFORE STUCK IN THE ON POSITION WITH NO RECOURSE. ALL OTHER FUNCTIONS HANDLED BY TOUCHSCREEN WERE INOPERATIVE. TESLA ROADSIDE ASSISTANCE WAS CALLED ON MORNING OF AUG 1 FOR OIPTIONS, BUT RESET PROTOCOLS OFFERRED DID NOTHING TO HELP SOLVE THE PROBLEM. CAR TAKEN IN TO TESLA SERVICE CENTER ON AUG 2, WITH INOPERATIVE MCU IDENTIFIED AS THE CAUSE ON AUG 3. REPAIR COST ESTIMATED TO BE ABOUT $1500. I THEN FOUND OUT THE REPAIR WAS OUT OF WARRANTY ONLY BECAUSE TESLA HAD SHORTENED THE WARRANTY BY 2 YEARS AFTER I PURCHASED THE VEHICLE. IF THE WARRANTY WAS AS STATED WHEN THE CAR WAS PURCHASED, THIS REPAIR WOULD HAVE BEEN COVERED BY TESLA. SORRY, NO USEFUL PICS OR DOCS APPY AT THIS POINT, AS REPAIR HAS NOT YET BEEN MADE.

NHTSA ODI 11343533

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.

NHTSA ODI 11343258

MAIN COMPUTER SYSTEM DIED. ALL SCREENS STOPPED FUNCTIONING (INCLUDING SPEEDOMETER). CAR WOULDNT LOCK/UNLOCK. TESLA SAID THE MCU HAD TO BE REPLACED AND THEY WERE GOING TO CHARGE ME BECAUSE IT WAS 5 DAYS OUT OF WARRANTY.

NHTSA ODI 11342632

MY SCREEN GOES BLACK. THIS RECOVERS OVER TIME WHEN I REBOOT, BUT IF I AM CHECKING MILEAGE THE SCREEN GOES BLACK AGAIN. PEOPLE WHO HAVE THE SAME CAR HAVE TOLD ME THAT THIS IS A KNOWN PROBLEM WITH THE COMPUTER MEMORY FOR THIS VEHICLE. THIS HAS HAPPENED WHEN THE CAR IS STATIONARY AND MOVING ON A CITY STREET. I AM NOT ABLE TO GET A SERVICE APPOINTMENT UNTIL AUGUST 7, 2020

NHTSA ODI 11342178

THE MCU SCREEN ON MY TESLA WENT OUT AFTER RETURNING TO THE VEHICLE FROM IT BEING PARKED. SCREEN WOULD NOT TURN ON EVEN AFTER MULTIPLE REBOOTS. WAS ABLE TO DRIVE THE VEHICLE BUT LOST ALL CONTROLS THAT THE MCU SCREEN CONTROLS, LUCKILY IT WAS A COOLER DAY AND I DIDN'T NEED THE AC BUT HVAC IS INACCESSIBLE WHEN THIS GOES OUT AMONG OTHER SAFETY ITEMS. PRIOR TO THIS THERE WERE TIMES WHEN THE SCREEN WOULD BE OUT AND THEN COME ON AFTER A FEW MINUTES. THIS IS A KNOWN ISSUE WITH TESLA MODEL S/X VEHICLES BUILT BEFORE APRIL 2018. THEY SEEM TO ALWAYS FAIL OUTSIDE WARRANTY BUT THIS SHOULDN'T BE AN ISSUE AND CAN CAUSE HARM BECAUSE OF WHAT THE MCU CONTROLS.

NHTSA ODI 11342022

THE MCU DIED, PREVENTING USE OF THE BACKUP CAMERA CREATING A HAZARD WHILE BACKING UP WITH LOW VISIBILITY.

NHTSA ODI 11342059

MCU-TOUCHSCREEN EMMC FAILURE - MCU1 (VERSION 1) UNIT IN TESLA, INCLUDING MY 2016 TESLA MODEL X HAS AN EMMC CHIP THAT CAUSE FAILURES RESULTED IN WHOLE CENTRAL SCREEN GOING BLANK, FREEZES, AND AS RESULT MAKE CAR NOT-OPERATIONAL - NO NAVIGATION, NO CLIMATE CONTROL, NO OTHER CONTROLS OF THE VEHICLE, SINCE IT'S ALL DRIVEN THROUGH CENTRAL SCREEN. CONSIDERING MY CAR IF JUST 3.5 YEARS OLD, THIS IS REALLY CONCERNING AND TESLA SHOULD ADDRESS THIS TECHNICAL FLAW.

NHTSA ODI 11342084

THE MCU IN THIS 2016 MODEL X DOES NOT FUNCTION PROPERLY. IT WILL RANDOMLY CRASH AND GO COMPLETELY BLACK WHILE THE CAR IS IN USE WHICH STOPS ALL FUNCTIONALITY OF THE HVAC, RADIO/AUDIO, NAVIGATION, ETC. THE CAR ALSO CONTAINS A BROWSER WHICH DOESN'T WORK AT ALL. THE MCU IS EXTREMELY LAGGY WHEN IT IS WORKING.

NHTSA ODI 11341787

MCU1 THE MAIN COMPUTER CONTROLLING THE CAR CRASHES FREQUENTLY AND DISABLES THE CAR

NHTSA ODI 11341381

TESLA X MODEL 2016 ERRATIC BEHAVIOR NOTICED. SYSTEM WILL POWER UP NORMAL BUT SOME OF THE SAFETY FUNCTIONS WILL NOT BE AVAILABLE. CENTER SCREEN WILL NOT RENDER PROPERLY LIKE IT IS FROZEN. VERY FRUSTRATING. YES TESLA IS A LOW MAINTENANCE BUT IF THE COMPUTER MODULES / MONITOR THAT ARE HEART OF THE CAR ( ENGINE) THERE SHOULD BE EXTENDED WARRANTY ON IT. I AM TOLD THAT MCU UNIT NEEDS TO BE REPLACED LIKE SAYING YOUR ENGINE NEED REPLACEMENT AFTER 4 YEARS. THERE SHOULD BE STANDARDS ON THE COMPUTER HW DEVICES ON ELECTRIC CARS THAT ARE MORE ROBUST AND LONGER LASTING. SO MUCH FOR LOW MAINTENANCE COMPARE TO CARS WITH ENGINES.

NHTSA ODI 11341071

MAIN DISPLAY STOPS FUNCTIONING, CAUSING LOSS OF SEVERAL NECESSARY AND SAFETY FUNCTIONS INCLUDING BUT NOT LIMITED TO: VEHICLE CONTROL, CLIMATE, NAVIGATION AND VEHICLE STATUS. THIS IS A KNOWN PROBLEM FOR TESLA MODELS S AND X SOLD BEFORE 2018.

NHTSA ODI 11341105

SUDDEN UNEXPECTED FAILURE OF MCU1-THE MAIN CONTROL TOUCH SCREEN OF THE CAR. LIMITING ACCESS TO KEY SAFETY FEATURES SUCH AS BACK UP CAMERA AND OTHER VEHICLE CONTROLS. THE VEHICLE HAD AN UNUSUAL DISPLAY BEHAVIOR AND TOOK A PROLONGED TIME TO WAKE UP, THEN THE CENTER DISPLAY FAILED TO TURN ON AT ALL. MANUAL RESET ATTEMPTS FAILED.

NHTSA ODI 11340925

MY MCU WENT OUT AND I HAD NO WORKING HORN OR BLINKERS. I WAS ALMOST SIDE SWIPED BY A TRUCK THAT WAS COMING INTO MY LANE AS IF I WASN'T THERE AND I TRIED TO BLOW MY HORN AND I HAD NO HORN TO ALERT HIM OF PRESENTS IN THE LANE HE WAS AND DID MERGE AND I HAD TO HIT MY BRAKES TO AVOID HIM FROM CRASHING INTO US! THIS UNSAFE FOR A CAR THAT IF YOUR MCU GOES OUT YOU LOOSE SOME OF YOUR SAFETY FEATURES THAT COULD SAVE YOUR LIFE!

NHTSA ODI 11340259

DURING CHARGING, THE CAR MCU SCREEN WENT BLANK, AND THE CAR WAS NOT ACCESSIBLE OR CONTROLLABLE. VEHICLE WAS UNRESPONSIVE UNTIL TOW TRUCK DRIVER BYPASSED UNIT BY JUMP STARTING THE 12 VOLT BATTERY. LIMITED CONTROL WAS REGAINED. CAR WAS DRIVABLE, BUT THE REAR DOORS WERE INOPERATIVE. I AM NOT SURE WHAT OTHER SYSTEMS WERE INOPERATIVE. I AM CONCERNED ABOUT THIS HAPPENING DURING DRIVING OR GETTING STRANDED IN A REMOTE PLACE.

NHTSA ODI 11339512

WHILE HIGHWAY DRIVING THE MAIN MCU FROZE DUE TO A MANUFACTURER KNOWN MEMORY CORRUPTION DEFECT AND WOULD NOT REBOOT. THIS DEFECT FAILURE IMPACTS ACCESS AND CONTROL OF THE FOLLOWING SAFETY FEATURES, TURN SIGNALS, EMERGENCY BRAKE, EMERGENCY BATTERY DISCONNECT, FOG LIGHTS (FRONT AND REAR), AUTO HIGH BEAMS, REAR PEDESTRIAN CAMERA, SUSPENSION (INABILITY TO DISABLE AUTO LEVELING FOR TIRE CHANGING OR TOWING), TRACTION CONTROL SLIP START, SIDE MIRROR ADJUSTMENTS. BATTERY SAFETY LIMITS FOR ACCELERATION AND REGEN BASED ON ENVIRONMENTAL TEMPERATURE SAFETY LIMITS ARE ALSO DISABLED. THIS MCU FAILURE ALSO PREVENTS REFUELING (L3 DCFC STATIONS). AS WELL AS THE HVAC SYSTEM FROM BEING TURNED OFF WHILE PARKED. WHICH CONTINUED TO DRAIN THE PRIMARY BATTERY FOR SEVERAL HOURS. THE ODOMETER IS ALSO NOT AVAILABLE, AS WELL AS THE HANDS FREE BLUETOOTH FEATURE AND OTHER NON SAFETY FEATURES. THE INITIAL INCIDENT OCCURRED UNDER WARRANTY. THE MANUFACTURER SWITCHED TO A BACKUP MEMORY PARTITION TO REPAIR OR WORKAROUND THE DEFECT ISSUE TEMPORARILY. WITHIN 3 MONTHS, LESS THAN 1,000 MILES LATER, THE BACKUP PARTITION ALSO BECAME PERMANENTLY CORRUPTED AND REQUIRED A COMPLETE REPLACEMENT OF THE UNIT, OUT OF WARRANTY.

NHTSA ODI 11337992

CHIP FAILURE IN MCU CAUSED TURN SIGNALS TO STOP WORKING AT APPROX 65,000 MILES. KNOWN DEFECT TO TESLA AND SHOULD BE REPLACED AS A RECALL AS THEY CHANGED THE CHIP TYPE FOR VEHICLES MADE IN 2018 OR NEWER DUE TO THIS DEFECT. THE FAILURE OF THIS CHIP IS A SAFETY ISSUE AND THEY ARE CURRENTLY CHARGING OWNERS $1500-$2500 TO FIX.

NHTSA ODI 11338002

MY VEHICLE'S CENTER DISPLAY (MCU) IS STARTING TO SHOW SIGNS OF FAILURE ON ACCOUNT OF A FLAWED DESIGN THAT DEPENDS ON AN EMMC MEMORY COMPONENT THAT IS KNOWN TO FAIL CATASTROPHICALLY AFTER SEVERAL THOUSAND WRITE CYCLES, CAUSING LOSS OF CRITICAL ADAS AND REAR VIEW CAMERA FUNCTIONS, HVAC CONTROLS, AND OTHER BASIC VEHICLE FUNCTIONS. NOW, I AM FACING THE PROSPECT OF HAVING TO PAY TESLA THOUSANDS OF DOLLARS TO REPLACE THE ENTIRE MCU IN MY JUST-OUT-OF-WARRANTY VEHICLE. TESLA HAS TACITLY ACKNOWLEDGED THE SAFETY IMPLICATIONS OF THEIR ORIGINAL DESIGN BY MODIFYING IT TO USE A MORE ROBUST MEMORY COMPONENT IN 2018, AND THEY SHOULD BE MADE TO RECALL PRE-2018 MODELS TO ENSURE THAT NOBODY ELSE HAS TO ENDURE WHAT I AND MANY HUNDREDS OF OTHERS HAVE EXPERIENCED.

NHTSA ODI 11337289

CAR WAS PARK FOR A FEW DAYS. GOT IN THE CAR AND THE MAIN CONTROL SCREEN DID NOT COME ON. I RESTARTED THE CAR A FEW TIMES AND NOTING, CAR WAS ABLE TO BE DRIVEN BUT WHIT NO ACCESS TO AC, RADIO, BACK UP CAMERA AND MOST IMPORTANT TURN SIGNALS, SINCE ALL THE CONTROLS ARE IN THE CENTER SCREEN. I CONTACTED TESLA AND WAS ABLE TO DRIVE IT, CAUTIOUSLY SINCE THE REVIEW CAMERA ACTS AS A BLIND SPORT MONITOR FOR ME. TESLA REPLACE THE CENTER COMPUTER UNDER EXTEND WARRANTY, WITCH HAS A $200 DEDUCTIBLE. *TR

FAILURE AND REPLACEMENT OF MCU TOUCHSCREEN PANEL IN MY MODEL X. COULD NOT SAFELY OPERATE THE VEHICLE BECAUSE I WAS UNABLE TO EXTEND SIDE MIRRORS, USE BACK-UP CAMERA, TURN ON/OFF AC OR HEATING OR USE NAVIGATION. OTHER SAFETY FEATURES REQUIRING USING OR SEEING THE TOUCHSCREEN PANEL WERE NOT ACCESSIBLE. VEHICLE 7 WEEKS OUT OF 3 YEAR WARRANTY BUT ONLY HAD 20,039 MILES ON IT. TESLA SAID I NEEDED TO PLAY FOR A NEW TOUCHSCREEN PANEL. AFTER A STRENUOUS DISCUSSION TESLA AGREED TO DISCOUNT THE REPAIR BY 50%. I STILL HAD TO PAY $841.63 FOR SOMETHING I FELT WAS A SAFETY ISSUE. LUCKILY THE CAR WAS PARKED AND AT HOME AT THE TIME OF THE FAILURE. IT COULD HAVE BEEN CATASTROPHIC IF IT HAPPEN WHILE DRIVING. I FELT THE TOUCHSCREEN PANEL FAILURE WAS CAUSED BY A MANUFACTURING DEFECT AND SHOULD HAVE BEEN REPLACED AT NO CHARGE. ALSO, IF TESLA FOUND IT HAD A HISTORY OF THESE PANELS FAILING, THEY SHOULD HAVE DONE A RECALL. IN NO WAY SHOULD SUCH A CRITICAL COMPONENT FAIL IN A VEHICLE THAT IS 3 YEARS, 7 WEEKS OLD WITH JUST OVER 20,000 MILES ON IT. *TR

NHTSA ODI 11331037

THE MCU (THE CAR'S CENTER SCREEN) WOULD NOT TURN ON. THE CENTER SCREEN CONTROLS EVERYTHING IN THE CAR INCLUDING ALL THE UPDATES. SINCE THE CENTER SCREEN DIDN'T WORK, AND UPDATE WAS NOT ABLE TO PASS THROUGH, AND IT ESSENTIALLY MADE THE CAR NOT DRIVABLE. THE CAR WAS IN THE TURN OFF MODE AND WOULD NOT TURN ON. *TR
