2016 TESLA MODEL S Electrical System Problems

My 2016 Tesla Model S (45,500 miles) is experiencing a complete failure of the Media Control Unit (MCU1), resulting in a total loss of the rearview camera display and defrost/defogging controls. This is a critical safety hazard. The unit was previously replaced by Tesla in 2021 under NHTSA Recall 21V-035. However, this replacement part has failed again after only a few years of low-mileage use. Tesla Service is refusing to provide a free repair or a goodwill discount for an MCU2 upgrade, claiming the 'recall repair' only had a 1-year warranty. It is unacceptable that a safety-critical component replaced under a federal recall fails twice in 45,000 miles. Tesla has failed to provide a permanent fix for the eMMC defect identified by NHTSA. By refusing to restore the camera functionality without charging full price, Tesla is knowingly allowing a safety defect to persist. I request an investigation into these premature...

-Airbag warning light on -Horn not working -Steering wheel scroll buttons not working -Clicking noise when turning wheel This failure occurred during normal driving. Airbags will not deploy and horn is inoperable, creating a safety risk myself and my family. I have never been into any accidents and have only driven normal. These safety systems should not fail. This is a manufacturing issue.

While driving on the freeway in the fast lane at 75 MPH I80W, the car began a loud humming sound that came from the rear. My passenger and I noted that it was significant sound that we took a video to record the sound. I was the driver and I noticed that the sound increased as I accelerated. Then without any warning the car began to decelerate and no longer accelerated. The car slowed considerably to 35 MPH and it became a major safety issue because I had to cross all lanes of traffic at this slow speed. It was only after the car had completely shut down that the warning messages began to display. I reached the side of the road and we waited for the tow truck driver for about an hour. Subsequently, the car was towed to a Tesla dealer near my home. I was informed that...

I am writing to formally report a recall-related safety defect that occurred after the eMMC recall service on my vehicle’s Media Control Unit (MCU). Following the recall, the display adhesive began to leak and the screen started separating from its frame. The adhesive continues to drip onto the dashboard and the display shows signs of delamination. This is a safety issue that directly affects driver visibility and may result in electrical contamination inside the MCU. Under federal law, Tesla is required to correct any defect that is related to or arises from a recalled component. This obligation is clearly stated in 49 U.S. Code Section 30120 and 49 CFR Section 573.6. The adhesive leakage and display delamination meet the definition of a related safety defect under 49 CFR Section 573.5(c) because the problem is connected to the same system that was recalled and repaired. A manufacturer performing a recall repair...

The center touchscreen in my Tesla Model S developed a yellow discoloration and later began leaking a sticky fluid from the edges of the display. This fluid appears to be seeping from inside the screen and emits a noticeable odor. The touchscreen is the primary interface for controlling most of the vehicle’s safety-critical systems, including the backup camera, gear selection, climate control, lights, and driver assistance settings. The leak causes visible streaking and distortion on the display. This directly impacts the rearview camera feed — making it harder to see obstacles or pedestrians when reversing — which is a federally mandated safety feature under FMVSS 111. The problem worsens in hot weather and may result in fluid dripping onto electronics below, creating an electrical hazard or sudden display failure while driving. This appears to be a known design flaw in which the adhesive or seal inside the display fails over...

While the car is parked and locked the rear driver side door opens in its own. The door handle does not present itself and is scheduled for repair. This is new and started happening today. Despite how many times I close it. It opens on it own. The door is locked when this happens. Door sitting still. Plugged in to charge and locked. The door opens on its own. It unlatches, Does not fully open.

My driver's side of the vehicle looks like it's melting. I was informed by the service advisor at Tesla that this is a common issue, and the computer needs to be replaced at my expense.

Component Failure: The Tesla NEMA 14-50 charging adapter for my 2016 Model S malfunctioned, causing overheating that melted a prong and led to an electrical fire. The defective adapter appears identical to those in Tesla's November 2016 recall, though mine was designated "not affected." The damaged adapter and charging cable are available for inspection. Safety Risk: This malfunction created a serious fire hazard endangering myself and my property. The electrical fire damaged both my vehicle and charging equipment, and the fire could have spread to my home, potentially endangering my family and neighbors. Verification: I took the damaged adapter to the Tesla Service Center in Colorado Springs, where technicians acknowledged the damage but refused to replace it under the recall. They visually confirmed the melted prong and fire damage. Manufacturer Response: After the incident, I contacted Tesla Corporate requesting replacement of the defective equipment. They responded that they don't believe...

The contact owns a 2016 Tesla Model S. The contact stated that while driving at undisclosed speeds, the instrument cluster became inoperable on several occasions. The contact stated that the failure had occurred several times. The vehicle was taken to the dealer; however, the contact was informed that the failure would reoccur unless the vehicle was updated with a new infotainment center and a faster processor. In addition, the contact stated that the vehicle had been taken to the dealer several times due to the failure. The contact stated that recently the instrument cluster and the ECM were replaced. In addition, the vehicle recently received a software update. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 73,000.

The contact owns a 2016 Tesla Model S. The contact received notification of NHTSA Campaign Number: 23V838000 (Electrical System) however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Received and OTA notice on the dashboard that states "Battery Fuse replacement" is required. The fuse is due to a Li-ion battery that wears out for a safety system. Life expectancy of the battery is 10 years. It has not lasted 8 full years. This is stated as a safety issue and Tesla has since redesigned this item to not required the batteries. I have alerted Tesla about this issue, have not had a reply, as yet. The vehicle can be operated without this safety device, which seems inappropriate. I feel this should be replaced under warranty and/or recall - but it appears Tesla will want to charge an excessive amount of money.

Driving 75mph on cruise control. Car sensed a vehicle in front of me (which there were no vehicles in sight) my Tesla started flashing the red car light and making the alert noise. My vehicle automatically slammed on the brakes dropping me to about 40mph instantly. My greatest fear continuing to drive this vehicle is if I use cruise control, and it senses a vehicle in front of me without their actually being a vehicle and slams on the brakes again myself or someone is going to get hurt. This has the potential to cause death or cause severe injury.

Sudden unintended acceleration appeared to cause the Tesla while parking the car on the street in front of home accelerate go out of control and crash into the home totaling the car and damaging the house. Two days prior the vehicle was brought into a Tesla service location where Tesla replaced the 12 volt battery that they believed was causing the car not to power on properly at that time. After the crash and googling to see if others suffered similar issues it appears the NHTSA recently reopened a review of sudden unintended acceleration and this incident seems to align with concerns of the petitioner [XXX] . The police filed a report and it’s at the towing place where the insurer Allstate is going to evaluate the car for a total loss.

Dear NHTSA, I am writing to file a complaint regarding a SUA incident that occurred on October 20, 2023, involving my 2016 Tesla Model S. On the day of the incident, I pulled into my garage and began to park my car. When I pressed the brake pedal, the car suddenly accelerated forward, crashing into the garage wall and totaling the vehicle. The garage wall was severely damaged and will need to be rebuilt. This is not the first time that my Tesla has experienced SUA. In 2017, I filed a complaint with NHTSA regarding a similar incident. In my previous complaint (issue # 11000097 dated June 19, 2017), I described a similar incident that occurred in December 2016. At the time, Tesla denied that the incident was caused by SUA and no further action was taken. I am convinced that the SUA incident on October 25, 2023, was caused...

The contact owns a 2016 Tesla Model S. The contact stated that over time, the adhesive for both the forward display and center console had degraded to the point that both components were able to move freely. The contact stated that the center console eventually lost electrical power, and as a result, the contact lost control and visibility of important vehicle safety features and information. The vehicle was taken to the dealer, who was unable to provide a specific diagnosis, but the vehicle was repaired after replacing the forward display and center console. The manufacturer was not notified of the failure. The failure mileage was 58,000. The VIN was invalid.

The glue that was used on the screen of the Tesla has been leaking and the service center refused to pay for the repairs. The glue is now exposed into the car and outside of the screen and is toxic. I am now breathing toxic glue and its giving me and my family headaches when we are inside of the Tesla.

At 22 degrees fahrenheit, the vehicles cabin heat shut off after hearing a noise. The Noise appeared to be a broken cabin heating element. The window screen quickly fogged, and water began attaching to the outside of the windscreen, building up as ice. The windscreen was completely almost blocked. This problem has appeared common in my online research. I was informed by a non manufacture repair business that the issue became apparent during the low temperature cold weather in December 2022. The vehicle will be inspected by the manufacture. No warnings, alerts, or service indicators were show. The vehicle is still showing proper operation.

While on the road/highway, the screen goes blank and soon starts rebooting itself. This is a big distraction and a matter of anxiety for the driver who fears sudden stopping of the car till the screen comes back up in a few minutes. This has happened to me intermittently many times. I have reported it several times but nothing was done since the technician at Tesla couldn’t repeat it the one time they may have test driven the car. That is the problem with intermittent issues. But for me, that one more time it happens next time, and I get anxious and distracted, it may result in an accident. I think this is a serious safety issues that many other Tesla owners have reported as seen on the web. Since your form asks for one specific date of incident I have indicated one approximate date but this has happened several...

The contact owns a 2016 Tesla Model S. The contact stated that while driving at an unknown speed, the electrical system intermittently failed. The contact stated that the turn signals failed to sound, the back-up camera was blank or was sometimes distorted. The contact stated that he was concerned for his safety while driving. No warning lights were illuminated. Additionally, the contact stated that two years ago, the vehicle performed a software update and afterwards, the electronics failed to properly operate. The vehicle was taken to the dealer where it was diagnosed that the failure was a known issue, and that the contact needed to wait for a software update. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed to wait for the software update but no further assistance was provided. The failure mileage was unavailable.

The main display in the vehicle is leaking very sticky hazardous fluid. Sometimes display goes out, sticky fingers make screen issues worse when so many controls are handled electronically. Tesla refuses to correct issue without spending $2000+ with dealer. This started 3 years ago. Leaking fluid on LCD is both main display and driver heads up dashboard. Huge safety issue with sun reflects on the bubble portions. Hard to read.

CPU compatibility to existing OS and memory system causing multiple failures during driving with: 1. instrument cluster reset or reboot (temporarily disables all controls related to buttons/knobs on steering wheel and possibly other safety functions), 2. main nav/computer screen reset or reboot (temporarily disables all controls), 3. auto braking activation (cannot be disabled by user) enabled at dangerous and unpredictable times of city traffic, 4. backup camera picture not updating/frozen during backing uo vehicle, creating illusion of: a. not moving when in reverse while driving, b. not showing objects that may be directly behind vehicle when in reverse Manufacturer (Tesla) service ticket opened and closed as “resolved with memory reset” without follow-up if problems still occur

I took my car in for the tesla video card replacement voluntary recall. After the "repair," my display screen acts erratically and visually becomes distractive. So far the service centers are trying to UPSELL me a new system to replace the current "repaired" system for $1500. I have had no luck with them taking responsibility for this issue. The big screen flickers the navigation screen and also distorts the items on the screen. As of yet, they keep saying this is normal function/behavior and all I have been asking is to have the screen operate as it is intended. (which it was prior to the chip update). Also, I believe the issue is also affecting the audio in the car.....at times the sound has become distorted and think that sound is absent from the turn signals. I know the audio system must have been impacted by their "repair" because initially...

The recent upgrade of the Tesla MCU UI (User Interface) firmware from V10 to V11 has significant User Experience problems creating a less safe vehicle. Standard pieces of automotive functionality have been moved off the main screen and into sub-menus. Two weeks ago, my car was forcefully or accidentally (may be my fault) updated to the V11 UI. To my dismay the window defrost button was moved from a single press on at the bottom of the touchscreen to multiple precise presses. I experienced how unsafe this is while driving in northern New Mexico on a snowy curvy mountain road after sunset departing Bandelier National Monument. The front windshield began fogging up as I reached 50 mph on the one lane 55mph speed limit road. Previously, a quick glance at the screen would be sufficient to make sure my finger was over the correct button. But now, the defroster button...

I was notified of this recall in March/2021 and Tesla says they have no time to fix it and they will schedule my appointment at some point. My Navigation and other key functions freeze frequently in busy metropolitan areas as well as rural and fails to keep up with notifications causing unsafe driving conditions. The remedy they suggested was to delete my driving navigation history to free up space which takes a ridiculous amount of time and only temporarily solves the problem. The recall notice is below.

A heater which warms the large battery which powers Tesla's EVs burned out while I was charging my vehicle at a Tesla supercharger. It appears to have been caused by a high voltage 'short' from moisture. I was able to continue driving the vehicle for over 100 miles, but did not have 'regenerative' braking. This made the stopping distance much longer - nearly causing a collision. When I stopped at another Tesla supercharger the car would not charge and had to be towed. This defect should warrant a recall.

2 problems: 1.) the eMMC chip for the screen has not yet been replaced due to supply issue? 2.) the battery heater stopped working causing driving ability issues. This should be a recall. the car lost both acceleration and braking power and made it dangerous to drive. I was unable to charge the battery, and had to have the car towed a long distance, costing me over $1,000 to have repaired.

My Tesla is under a recall for bad memory. My Tesla constantly reboots. I often have to wait several minutes from when I get in the car until it is ready to drive with all functions. I sometimes am forced to drive with the center screen not working. This takes away my backup camera. A required safety feature. Tesla says the part is not available. I request a reliable loaner until they get the part repaired under recall.

The doors on my Tesla are electronic from the inside and outside. Sometimes the car will not let me out or in, especially in the rear drivers side door where the kids are. It will not open the door and presents a huge safety issue. My sons was trapped in the door previously and we couldn't get the door to open - it took about 5 cycles of locking and unlocking the car for the doors electronic door handle to finally allow the door to be opened Recently there was a lawsuit for a similar issue in which a man became trapped inside a Tesla and died of smoke inhalation because the doors would not open and first responders couldn't get in the car either. I contacted Tesla, who was able to diagnose my car and create a repair estimate for the malfunctioning door handles without even looking at the...

The contact owns a 2016 Tesla Model S. The contact stated while driving 65 MPH, the instrument panel inadvertently turned blank and the defroster became inoperable. There were no warning lights illuminated. The contact stated he was able to continue to drive the vehicle. The vehicle was taken to the dealer who informed the contact that they could not repair the vehicle; however, the vehicle memory was reset. The contact stated that the failure reoccurred while driving. The vehicle was taken back to the same dealer who informed the contact that they could not assist and advised him to depress an unknown button on the instrument panel to record the time of occurrence whenever the failure reoccurred. The contact stated that the failure reoccurred shortly after receiving the recall notice for NHTSA Campaign Number: 21V035000 (Back Over Prevention, Visibility, Exterior Lighting). The contact stated he had not been contacted by...

Tesla refuses to refund my repaid related to NHTSA Recall No: 21V-035. I made a repair because of this issue back in March 2021 and soon after a recall notice came out on March 22, 2021 which I received at a later date due to the pandemic. I requested a formal refund but Tesla refuses to process my claim. I am bringing this to your attention as I believe this is unfair and Tesla should be accountable for the defective part they placed in my car. Please let me know if you need additional details or information. I think you in advance for your help.

My Tesla Media Control Unit v2 went to a black dark screen while the car was still on. I just put the car in reverse and the instrument cluster and control unit froze, then did 3 cycles of restarts before coming back on. The whole time I had to press the brake pedal because I wasn't sure if the car had been put back into park by default. Should I have released the brake pedal the car may have rolled into the street and caused an accident if the system failed to allow me to depress the break pedal again. Tesla is doing a "remote" diagnostic but is being very secretive and or non-transparent about the cause of the issue. There was no warning and the cluster and media control unit just froze. This has occurred on 2 previous occasions as well, though thankfully those times I was parked and...

This automobile has had the Tesla recall completed, replacing the 8GB with the 64GB. However, this fix is temporary and after a few months the control and information screens are malfunctioning and with ever-increasing frequency. I understand Tesla’s recent update ensures basic driving functions will continue to be operational during a screen blackout but it’s at best distracting and at worst plain dangerous depending on how lights/HVAC are set prior to the screen freeze, not to mention distractions associated with a sudden loss of navigation and an inability to control other components. As a frequent highway driver this is dangerous, even after experiencing various versions of this event. Per Service Dept., the only existing actual (non-temporary) repair for this is replacement with the newer version of the MCU, yet Tesla insists on using language as a loophole, calling the MCU2 an upgrade- which it was, but now as the sole...

My Tesla regularly has the instrument panel and center display go completely black and turn off while driving. This includes not being able to adjust climate control, access rear view backup camera, use lane indicators and determine speed or status of autopilot and driving safety features. I have noted this to Tesla Service Center on 3 occasions and they refuse to provide thr necessary repair under the applicable recall notice 21V-035.

THE VCM MALFUNCTION IS CAUSING MY CAR TO SOMETIMES NOT EVEN TURN ON AND IT HAS BEEN OVER 6 MONTHS SINCE I STARTED HAVING THIS PROBLEM AND STILL IT'S NOT FIXED.

REAR VIEW CAMERA STOPPED WORKING, DO TO MEMORY BEING FULL.

DISPLAY BLANKED OUT. TURN SIGNALS, SOUND FROM CAR, AND OTHERS DID NOT WORK. THIS HAPPENED A COUPLE OF TIMES. CAR DROVE OK EXCEPT FOR DOUBT ABOUT WHAT WAS WORKING. WAS ABLE TO FIX IT BY GOING TO INTERNET AT HOME AND PERFORMING VARIOUS TECHNIQUES.

MY CENTER CONSOLE AND MCU CONTINUES TO LOCK UP AND RESET. I HAVE ALERTED TESLA SERVICE CENTER MANY TIMES TO THIS ISSUE AND THEY TELL ME I HAVE TO PAY FOR THE UPGRADE OF THE MCU. THEY ACTUALLY KNOW THEY HAVE A PROBLEM AND TELLING ME THAT MY CAR DOES NOT FALL IN THAT CATEGORY FOR A RECALL. I REALLY THINK THAT THEY ARE TRYING TO CULL OUT THE FOLKS THAT ARE NOT PERSISTENT, AND FOR SOME REASON THEY STATE THAT I DON'T HAVE A PROBLEM. THE PROBLEM ACTUALLY CAUSES A GREAT DEAL OF SAFETY AND ANXIETY BECAUSE MANY OF THE DRIVING FUNCTIONS ARE DISABLE UNTIL I RESET THE CAR. THIS IS UNACCEPTABLE GIVEN THAT THE CAR COST ME OVER $90,000

I AM SURE YOU ARE AWARE OF THIS PROBLEM WHICH WAS JUST ANNOUNCED FOR RECALL - CENTRAL MCU UNIT CAUSES BLACK SCREEN WHICH STOPS MAJORITY OF CAR FUNCTIONS TO OPERATE. HOWEVER - HERE IS A NEW TWIST! MY UNIT WAS REPLACED 2 WEEKS AGO AND WITHIN 48 HOURS THE PROBLEMS ONGOING BLACK SCREEN PROBLEMS RE-APPEARED TWICE (PLEASE, SEE ATTACHED IMAGE). BROUGHT BACK THE VEHICLE TO TESLA REPAIR CENTER AND AFTER A WEEK TESLA'S RESPONSE - "WE RESET ERRORS AND YOU ARE ALL SET". THESE ORIGINAL MCU1 UNITS ARE FLAWED AND ARE A DANGER TO DRIVERS BECAUSE PROBLEMS CAN HAPPEN ANY TIME - WHILE YOU ARE DRIVING, BACKING-UP, PARKING OR CHARGING. THESE ISSUES CANNOT BE RECTIFIED ON THE ROAD AND ARE A TOTAL HAZARD. REPLACING ONE DEAD MCU1 WITH ANOTHER ONE IS SIMPLY DELAYING THE INEVITABLE. TESLA IS AWARE OF THE FUNDAMENTAL DESIGN PROBLEMS WHICH IS WHY THEY NOT ONLY INTRODUCED...

MY 2016 TESLA (MANUFACTURED IN 01/2017, MILEAGE OF 60,400) HAD THE ISSUES WITH THE INSTRUMENT SCREEN BLACKOUT SEVERAL TIMES. EACH TIME, I LOST CONTROL OF THE TOUCH SCREEN, WHICH CAUSED THE LOSS OF REAR CAMERA VIEW, AC, LIGHT AND DRIVE CONTROL, ETC., ESPECIALLY THE FOGGED UP ON WINDSHIELD. THIS IS A DANGEROUS ISSUE. I SENT MY CAR TO TESLA SERVICE CENTER (TSC) IN MATTHEWS, NC ON 1/16/21 AND THEY REFUSED TO REPAIR MY EMMC AS MY CAR'S INSTRUMENT SCREEN COULD RESTART UP AND WAS NOT COMPLETELY DEAD. ANDY AT TSC TOLD ME THAT I'D HAVE TO WAIT FOR MY CAR TO DIE COMPLETELY AND TOUCH SCREEN BECOMES DEAD AND CANNOT BE RESTARTED IN ORDER FOR THEM TO SERVICE IT UNDER THE EXTENDED WARRANTEE. IRONICALLY, I PICKED UP MY CAR FROM TSC THIS PAST WEEKEND AND ON MY DRIVING HOME ON HIGHWAY I-85 SOUTH OUTSIDE CHARLOTTE, NC, I LOST MY TOUCH...

WHEN STATIONARY OR IN MOTION, BOTH ON CITY STREETS AND HIGHWAYS, AND EVEN TURNING THE FOLLOWING IS TRUE. THE CENTER INFOTAINMENT STACK BECOMES COMPLETELY FROZEN AND UNUSABLE. FOLLOWING THIS, IT WILL AUTOMATICALLY RESTART, HOWEVER DURING THIS ENTIRE TIME, VITAL SAFETY FEATURES CONTROLLED THROUGH THE CENTER INFOTAINMENT STACK ARE UNAVAILABLE, INCLUDING BACK UP CAMERA FUNCTIONALITY. I HAVE APPLIED FOR THE WARRANTY PROGRAM TESLA HAS FOR REPLACING THE MCU1, HOWEVER, EACH TIME THEY INFORM ME MY CAR DOES NOT MEET THE REQUIREMENT WITHOUT ELABORATING ANY FURTHER. HOWEVER, THIS IS CLEARLY A SAFETY ISSUE THAT THEY ARE IGNORING.

NO AUDIO WITH TURN SIGNALS. ANIMATION WORKED ON SCREENS, AND TURN SIGNALS WERE ACTUALLY WORKING, JUST NO AUDIO. CHECKED ALL EXTERIOR LIGHTS AND ALL WORKED INCLUDING BACKUP AND BRAKE LIGHTS. AFTER REBOOT OF THE MCU1 AUDIO WORKED.

I AM THE OWNER OF A 2016 TESLA MODEL S 90D THE "CENTER SCREEN" IN THIS CAR IS CENTRAL TO THE USE OF MANY SAFETY FUNCTIONS OF THE CAR, SUCH AS THE REVERSE CAMERA, HEADLIGHT CONTROLS, DEFROSTER CONTROLS, AND TURN SIGNAL CHIMES. THE SCREEN IN MY CAR HAS BECOME HIGHLY UNRELIABLE, OFTEN LOCKING UP, REBOOTING, OR FAILING TO RESPOND, CAUSING THE AFOREMENTIONED FUNCTIONS TO BE UNAVAILABLE. IT IS MY OBSERVATION THAT THESE FUNCTIONS WORKED WELL IN THE PAST WHEN THE VEHICLE WAS ORIGINALLY DELIVERED, BUT HAVE DEGRADED OVER TIME AS TESLA HAS PUSHED SOFTWARE UPDATES TO MY CAR. I HAVE DISCUSSED THIS ISSUE WITH TESLA AND AM AWARE OF THE PROPOSED NHTSA RECAL OF THE CENTER SCREENS DUE TO A EMMC FLASH WEAR OUT ISSUE. TESLA HAS ASSURED ME THAT THIS IS NOT THE ISSUE WITH MY CAR, AND HAS REQUESTED THAT I WAIT FOR FUTURE SOFTWARE UPDATES TO RESOLVE...

THE DISPLAY SCREEN HAS NOT BEEN WORKING PROPERLY. SOUNDS INCLUDING VOICE NAVIGATION AND TURN SIGNALS HAVE STOPPED WORKING. RESETTING THE SCREEN FOXES THE ISSUE FOR 1 DAY BUT THEN RETURNS. OTHER SAFETY SOUNDS INCLUDING PROXIMITY SENSORS ARE ALSO NOT WORKING.

THE CAR WAS PARKED AND RE-ENTER ABOUT 1 HOUR LATER, THE CENTRAL SCREEN WAS BLANK. ALL THE WINDOWS FOG UP AND CAN NOT DRIVER UNTIL ALL THE WINDOWS CLEAR UP. THE PIN TO DRIVER CAN NOT ENTER SCREEN WAS BLANK, HAS TO USED THE MOBILE APP TO START THE CAR TO DRIVE. ABOUT 20 TO 30 MINUTES INTO THE DRIVE, THE SCREEN REBOOTED TO NORMAL FUNCTIONS.

THE 2016 TESLA MODEL S MCU HAD BEEN SLUGGISH AND OFTEN TIMES FREEZES. THIS IS POTENTIALLY A RISK FOR DRIVING AS I CANNOT ACCESS OR SEE ANYTHING ON THE SCREEN. LOTS OF TIMES THE FRONT SCREEN AND THE MCU SCREEN TURNS OFF. I CALLED TESLA AND THEY DELETED THE ENTIRE HISTORY CACHING, BUT THAT WORKED FOR A BIT, BUT THEN WAS SLOW AND SLUGGISH. THE MCU WILL GO OUT A WEEK LATER. OFTEN TIMES, I WOULD GET IN THE CAR AND THE CAR WILL NOT BOOT UP FOR A COUPLE MINUTES. TRYING TO CHANGE SETTINGS ON THE MCU WOULD BE AN SLOW PROCESS. SOMETIMES THERE WERE GLITCHES WHERE YOU CANNOT SEE ANYTHING ON THE SCREENS LIKE THE SPEEDOMETER WHICH MAKES DRIVING DANGEROUS. MY CAR WAS UNDER WARRANTY AND I PURCHASED THE EXTENDED WARRANTY AND THEY WOULDN'T CHANGE THE MCU. I ENDED UP PAYING $2700 OUT OF POCKET TO REPLACE THE...

I HAVE TAKEN THE CAR IN FOR SERVICE 5 TIMES STARTING IN OCTOBER FOR THE SAME ISSUE. THE PROBLEM I AM HAVING IS MY MEDIA CONTROL UNIT CUTS OUT / GOES BLACK AND RESETS ITSELF. IT DOES THIS RANDOMLY INCLUDING WHEN I AM DRIVING THE VEHICLE. WHILE THIS DOES NOT IMMEDIATELY IMPACT MY ABILITY TO OPERATE THE VEHICLE IT IS DISTRACTING WHEN THIS HAPPENS WHILE I AM DRIVING. TESLA HAS ISSUED SOME ADVISORY ABOUT AN KNOWN ISSUE WITH THE MCU, BUT THEY CONTINUE TO TELL ME THAT A FIRMWARE UPDATE WILL RESOLVE THIS OR TO DO A HARD RESET ON THE SYSTEM TO RESOLVE THIS. THE HARD RESET TAKES 3 - 5 MINUTES TO RESET AND IS NOT AN ACCEPTABLE SOLUTION IN MY OPINION. I HAVE ATTACHED THE INVOICES WITH NOTES FROM THE SERVICE CENTER / TECHNICIANS FROM WHEN MY VEHICLE WAS BROUGHT IN TO SERVICE.

TESLA HAS A DAUGHTERBOARD MEMORY CARD RECALL IN PLACE, AND THE DISPLAYS IN MY CARD KEPT GOING BLANK FOR LONG PERIODS WHICH IS INDICATIVE OF THE MEMORY FAULT.
