My 2015 tesla model s with 33,270 miles has a non working touch screen or mcu1 that controls the car. After researching this a bit online it seems its a much too common problem and more of a defective part of the car. It is very hard for the operator to us e the car without it since it controls most of the car. Repair times are through the roof causing quite a bit frustration for the car owner. The unit failed while driving normal on a back road at a normal speed.
2015 Tesla Model S electrical complaints
Page 8 of 10: complaints 191 to 220 of 269, newest first, as owners wrote them.
Main display stopped working today (june 30th 2020). Now HVAC, radio, sunroof, rear camera, indicator light noise, and a few other functions don't work. This seems to be the emmc memory write failure issue. The car was stationary when I noticed the issues, since I just got into the car and immediately noticed main display was dead.
Center consul screen turn off and won't come back on can't use navigation backup camera no turn signal sound or radio sound or any sound involve the center counsel
Mcu manufacture defect mcu runs laggy and alters ability to use mcu in vehicle.
The infotainment computer mcu1 is known to fail prematurely due to software issues caused and not fixed in a timely manner by tesla. Basically the limited write cycles of flash memory are exhausted due to excessive logging up to a certain software version. My car shows the early warning signs including black screens on entering (car is not movable for several minutes) and reboots during driving. Full mcu failure is known to cause indicator lights to fail, automatic emergency braking to not engage, disabled fast charging and no accurate charge indicator (so risk of getting stranded), heating/ventilation stuck to most recent setting (no defrost), audio fragments being stuck on arbitrary volume, air suspension is stuck to possibly unsuitable settings and the speedometer is reverting to MPH instead of km/h without notification. If pin to drive is used, the car can no longer be unlocked and moved. Tesla does not acknowledge this problem and charges for full repair cost outside of warranty / drags cases of impending mcu failure until the car is out of warranty. Mcu1 can be replaced with mcu2 according to a tesla infotainment website; however only mcu1 replacements for the oldest cars (ap1 sensor level) are available to date despite announcement these would be ready in april 2020. Newer cars with longer remaining life can be upgraded upon invitation by tesla.
The vehicle's primary screen for controlling most functions, known as the mcu version 1, constantly crashes, while driving and stationary. When it is off, I cannot use my reverse camera, control heat/AC, not can I check various car statuses. It is a known defect with tesla. I am being told it will eventually stop working altogether and there will be a $2500 cost to replace it with the same mcu with the known defect.
My media control unit (ipad screen-like) crashes, is incredibly slow and doesn't load internet feature that was promised. Took to tesla multiple times and they said it's normal and their future updates will address this. This was said last year, and my internet still doesn't work (even under strong wifi). Crashes periodically and very slow.
Computer occasionally crashes and compromises the safety of vehicle because of a defect. Also door handles, all 4 have broken compromising safety, because of manufacturer defect.
Well docmented failure of a memory chip that has been docuteted to fail after a certin amount of read/write cycles, tesla has been well aware of this fault for years and has done nothing to address the issues leaving owners sometime stranded or reducled vehilce functionalty. Teslas respnose has been to replace the faulty system with a refurbish unit that will have the same issue in the futiure and charging the customer between 1500-2000 to replace.
Mcu1 memory chip problem starting to show symptoms of slowness, rebooting, non responsiveness and needs rebooting while driving to get it to work. When it crashes will break backup camera, turn signals, and ability to control defoggers which is extremely dangerous and should be recalled.
The mcu v1 is known to fail. It's become sluggish and black screens. Not acting as it should.
The mcu (main screen/computer) failed and needed to be replaced. All the mcu functions did not work during the failure. See photos of the blank screen and correspondence with tesla service.
Tl* the contact owns a 2015 tesla model s. The contact stated that the media control unit touch screen was inoperable. The contact stated that while attempting to recharge the battery, the system flickered and failed to charge. The contact stated that the back-up camera was also inoperable. The vehicle was undrivable. An independent mechanic went to the residence to inspect the vehicle and the contact was informed that the media control unit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 89,586.
The touchscreen is finally dead, wouldn't turn on. All settings related to the touchscreen is all gone, thus all essential functions controlled by the touchscreen is off, including backing up camera. I felt very unsafe to drive. The car would take a very long time to turn on. When I slowed down and stopped at a stoplight, it rolled backward since I didn't know that the creep mode was disabled with the dead touchscreen. I was lucky enough to notice the car rolling and stopped in time before hitting some other car.
The center console display of my tesla model s has abruptly stopped working. I can no longer access the majority of the features of my vehicle, such as turning on A/C, accessing GPS, controlling the sunroof, adjusting vehicle settings, adjusting my side mirrors, defogging the windshield, accessing the rearview camera, and any other setting that is controlled by the center display. This has made driving the car nearly impossible. Because of the low visibility of the rearview window, I heavily rely upon the rearview camera. Since center console display was off and hence no rearview camera, I ended up damaging my bumper into a low-profile object that otherwise would have been visible had the camera been enabled. I only drove my vehicle once and damaged it on the first drive with the center console off. I contacted tesla to have this problem fixed, but was told I would need to pay approximately $1,500.00 to replace the mcu with the exact same version. Further, this replacement would likely take a month to be fixed, rendering my vehicle effectively useless.
Touch screen failure. Screen went blank jan 3rd 2019 still under warranty.was able to reset after many tries. Parked car went to winter home. Returned april 16th same problem. Working with tesla through out problem. Finally tesla said bring the car in. Now out of warranty so had to replace mcu $2250.00
Center console display and computer failed as described in the federal safety agency pe20010, was replaced under warranty approximately january 2018. Replacement unit is now showing initial signs of same failure (extremely slow start-up now including blank instrument cluster when entering/starting car; cellular connectivity and navigation failures; unusual sounds or lack of auditory feedback for vehicle controls, blank black screen for backup camera, etc.)
Mcu failed. When it failed car would not shift into drive. Before failure mcu was constantly rebooting while driving. During reboot would lose headlights, turn signals, radio, and air conditioning. Complete failure occurred while stationary. Rebooting occurred while driving.
Tesla screen went completely black and will not come on. No back up camera, no turn signal, no radio, no A/C. This happened one morning when I went to turn the car on. Have tried reset. Made an appointment with tesla to repair but in the process of researching problem, have found this to be a known failure of many tesla's between 2014-2017. It is a safety hazard and tesla should be doing a recall. I am afraid to even drive my car to the service center for repair that is 15 miles from my home.
The main control unit for the center display screen has failed and will not display the vehicle controls including critical safety information and rear camera.
First it started with the back up camera not displaying when I would put the car in reverse, so I had to reboot the system. Few days passed then it did it again so I reboot ed the system again but this time my entire screen went black and it would not turn back on after days of rebooting the system. I took the car into tesla to check and they said my mcu needed to be replaced. The problem with the mcu going out is that it controls everything including the back up camera and it also controls the A/C and when the mcu went bad it left my A/C 24/7. It took a week for my to get my car in for service so my car has the A/C running 274/7 for a week. It took another 2 weeks for the service center to get the mcu in stock to repair my car. I am curious why the mcu went out only after a my warranty ends.
Regarding tesla model s vehicles (model years 2012-2018) that have an mcu failure due to a defective memory chip design, in addition to losing the backup camera when this fails, the turn signals also become inoperable. This happened to my vehicle. This is clearly a safety issue that must be addressed.
Tl* the contact owns a 2015 tesla model s. The contact stated that while the vehicle was parked, the central computer failed to operate as designed. The contact was able to drive the vehicle however, the early warning system, auto-pilot, rear back-up camera, and several other undisclosed electrical functions were inoperable. The vehicle was taken to tesla (140 university town center dr #138, sarasota, fl 34243, (941) 866-6597) to be diagnosed. The contact was informed that the media control unit needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and a case was filed. The approximate failure mileage was 37,400. *ln*jb*dt
Multiple issues with the touchscreen since purchase which required restart of the touchscreen. Issues happened while stationary as well as while in motion. Vehicle was still operational. Touchscreen finally died early 2020 and wouldn't restart. Has been replaced with new touchscreen and charged for new screen and replacement.
Car was stationary. Started tesla and main navigation and camera screen. Mcu failure results in loss of audible and visual features provided by the touchscreen, such as infotainment, navigation, and web browsing. This includes loss of rear camera image display when reverse gear is selected, resulting in reduced rear visibility when backing.
I submit this as additional data for the federal safety agency inquiry pe-20-010, tesla motors. The central screen and processor that run most of the non-driving electrics in the car died. The rear camera stopped working. The air conditioning was stuck on the same setting and would not go off. I needed to keep the car plugged in for 7 days until it was fixed since the climate control would draining the battery. Sounds associated blinkers didn't work. Oddly, the odometer also stopped logging miles. Since my car is out of warranty I had to pay $1886 to have it replaced during covid. Tesla service center was very helpful, but if this is a common problem, tesla should be fixing this free of charge. The car was drivable at a basic level but it was not fully functional. This first happened when the car started one morning, the car was stationary. I have attached repair invoice.
The main screen on the car (mcu) has had issues for over a year. It would sometimes just go blank while driving, or not turn on when getting in car or the response time so slow (which would be a real safety concern and caused me to pull off the road several times) the rear camera would stop working. I just paid $1639.00 to have the unit replaced, I was informed it was past it's useful life and would fail in the near future. These failures began happening in april of 2019 from parked to 75 MPH.
Tesla model s 2015, the main screen (mcu) goes black on/off. The manufacturer suggested doing a reboot, but it did not help. Now mcu is permanently black (non-functional) and the car has lost many functionalities, including two that are safety risks, there is no rearview camera and turn signals don't work.
This is related to current investigation of emmc failure. My vehicle experienced this problem at approximately 75k miles. Center screen went dark and backup camera, environment and acceleration/feature controls were no longer available. It cost $2000 to replace the mcu with a remanufactured mcu. I believe this is a factory design flaw that this memory chip fails so reliably due to exceeding write cycle duty in 4-5 years. This failure occurred while stationary and attempting to start the vehicle.
The mcu and the speedometer of my tesla are not working properly because the car manufacturer made a design error with the chip card and also on the way of the car controls the heat coming in to the cabin and it literally melts down the screen and the speedometer. Glue comes out every minute creating a dangerous situation because it gets sticky on your hands and while you try to remove it the screen goes black or freezes. The most common one is that the screen or mcu freezes up constantly and then the car can't be run. Hard reset work sometimes and sometimes won't . I contact them and they wanted me to pay $2600 for something it is their design flaw . This is a danger for the public safety and needs to be address by tesla replacing the mcu at not cost since it is a design problem . Those issues happens on both, while parked and driving , sometimes you can be driving and the screen won't work at all, you touch it and nothing works . As you can see on the pictures below , the glue will come down form the the screens and start going all over the car , that creates a hazard for driving and also possibly for a fire since the screen it is melting.
