Mcu failure like numerous other pre 2018 tesla's. Able to open doors, but main screen does not come in even after reset. No vehicle options available, including switching from park to drive or reverse. Fortunately, vehicle in the garage when found to be non operable. Set up appointment through the tesla app and tesla ordered a new mcu immediately without any contact with me.
2015 Tesla Model S electrical complaints
Page 6 of 10: complaints 131 to 160 of 269, newest first, as owners wrote them.
Went to the car one morning, was able to open the doors but found the primary screen was completely blank and non functional. Unable to shift the vehicle out of park. Fortunately the vehicle was in the garage and not moving. Scheduled a repair visit with tesla who immediately ordered a mcu which is now known to fail after time in all tesla model s's and x's manufactured prior to a certain date. I now need to arrange for the vehicle to be towed to tesla for them to repair a well known problem.
Tesla touchscreen went black while I was driving and I had to drive home without possibility to control most of the functions of the car such as lights, rear view camera, etc. This is known as the tesla mcu failure. Tesla does not want to own this issue and is asking customers to pay 1,500$ to replace with a refurbished mcu which will present the same issue 2-3 years from installation.
The mcu has a black screen a month ago. Which cause almost all car functions useless. Some safety functions such as turn signals, and backup-camera are not working. Car is drivable but it is not safe without stated functions. Charging takes a very long time.
2015 model s with 48,000 miles - touchscreen stopped worked, no ability to control car or have access to rear camera. Screen is totally black, with no option to reset. I wanted to document as this seems to be an issue the federal safety agency is currently investigating.
Screen that controls the entire car (large screen) stopped working completely. I have owned this car from new & the car is well taken care of: always garaged. This happened 07.13.2020 when I was going to the supermarket. I have no. Turn signals, daytime running lights, backup camera, radio, any miles on odometer reading, safety features or autopilot, bright lights, or any heat or A/C. This issue (what tesla calls mcu going out is a known issue in the last couple months. From my understanding the mcu is over working & tesla now installs a new type of mcu due to the flaw.

Middle screen went out putting the car in 'limp mode' happened in the middle of the night and we didn't have headlights or turn signals! Happened while driving about two hours from home when we tried putting a route in the touch screen after setting the automatic update for 2 am the following morning. The car has 101k miles the warranty expired at 100k miles. We notified tesla of the problems we've been having with our screen freezing and rear view camera randomly not working while it was under warranty but the techs said 'everything is fine and it must have been a fluke' now that the car is out of warranty the now suddenly know the problem and a solution! This defect is scary and left us stranded and unable to navigate to a safe area off the highway in the middle of the night without headlights!!! Why would they jeopardize safety over money!
Mcu central computer failed, so turn signals and backup camera are unavailable, as well as climate control, audio, navigation, vehicle status
Main touch screen wont turn on... Mcu, or now both screens are turning off and on and off and on, blinkers wont work , speedo wont work, radio, ventilation, basically everything wont work while this is happening, ( but you can still drive. I have a video but not the correct file type
Mcu screen on car failed.
Tesla model s main screen died. It's a known issue on early model s with mcdu version 1. A chip on the circuit board can only handle xxx amounts of writes, or write overs, then gives up. Screen goes blank. Most model s car functions are controlled on the main screen. My screen failed while driving. Unable to set or control charging. Unable to turn off A/C. Unable to hear turn signals. Unable to turn on or control headlights. Unable to close sunroof. Unable to change suspension settings. Unable to change steering settings. Unable to change lighting on the dash. Most features in the model s are not available.
Intermittent failure of the mcu1 ome, causing intermittent main screen blackout, turn signal malfunction, A/C disabling. Rebooting required mcu to be upgraded/replaced out of warranty
Car was sitting in my garage for a few days and when I got back in the mcu is totally black and known to be an issue with the emmc chip used reported by many other model s owners. As this controls majority of the functions, I can not control any of the car's instruments except for driving. Blinkers do not work, no AC, rear view camera doesn't work, battery range no longer visible so its quite unsafe to drive.
Mcu dead at 54,650 miles. Main control screen will not turn on. Has effected the following but not limited to. ' no aeb (advanced emergency braking) ' no controlling suspension height ' no manual control of headlight lights ' no blinker sounds ' turn signals inoperable ' 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 ' trip a/b ' profiles ' user settings ' homelink ' bluetooth pairings ' no rear view camera ' no parking sensors
Mcu1 failed in vehicle with ~47,000 miles. This failure impacts use of all features on the touchscreen, including backup camera, radio, A/C, maps, etc. Car is still operational, but turns on slowly.
On 7/16 after multiple calls to tesla support due to my screen in my 2015 tesla model s loading very slow and the blinkers not sounding (they had me reboot multiple times) I went to car and screen (mcu) was completely black/dead. My A/C was on all the time and I could not open charge port to charge. I was scared I would not get it into service so I drove it in there on 7/18 and explained all to the sales rep. He took car and I got a ride home. Today, 7/20 service called me and said mcu1 was dead and I could either pay 1275 to replace or upgrade to mcu2 for $2500. I told them that it was dangerous as signals were not even working and this should be covered as it was dangerous. They said no and I told them just to do the mcu1 replacement. Now I have to pay for that and they said it will be over a week to get it in. I don't know how the whole computer could fail this quickly and I am debating getting new mcu2 though that is too much money to pay. I am reporting this due to the danger and the fact that vehicle only has 66,000 miles on it. Tesla should definitely cover this as the car is a brick without it (no climate, music, settings, suspension control, or sounds coming from car to name a few). I could also not even schedule the service as it has to be done through the app and that would not connect to the car!!
Center console touchscreen stopped working completely. This happened overnight while the vehicle was parked in the garage.
Mcu failure. Scheduled appointments are several weeks out. Received update on 7/20 that mcu failed and tesla would need to order parts.
The master control unit stopped functioning all of a sudden when the car was stationary and hadn't been started in a few days. It was in my garage. This meant the car would drive but the rear camera would not function, the infotainment wouldn't function, bluetooth, air conditioning, etc. In short, no user controls.
Mcu computer failed, black center touch screen, no access to any vehicle controls, from air conditioning, radio, sun roof, back up camera, suspension, navigation, etc, this is a known issue for tesla mcu version 1 that tesla has refused to correct, from reading other blogs, this is something tesla knows will affect virtually all vehicles with mcu version 1 at some point, they have changed to mcu version 2 in 2018, but alll of us with older models are left with expensive repair bills with no recourse against tesla for this known manufacturing defect
The media control unit has gone out on my 2015 tesla, which has LED to the car not being able to be recharged (refueled), the AC being unsusable, and car unable to be locked among other issues. With teslas, the media control unit (mcu) is the powerhouse of the vehicle, containing all of the safety, A/C, and driving controls. With this being out of commision, there is no telling what features are usable or not. This leads me to worry about whether the airbags will deploy, whether the car will stop randomly on the freeway, or the car not being refueled. In fact, since this mcu has gone out, the car has not been able to be refuelled due to the mcu not allowing chage to reenter the car. This has lead the car to be unusable and unresponsive. This first occurred for me while diving on a city street, with nothing unusual being noted at the time. The car was responsive, driving normally, and completely usable and out of no where the vehicles mcu went black and the driving features were handicaped. The car was still able to drive, however, A/C components and unknown electrical features (such as airbags, seat belts, ABS) may have been compromised.
Media control unit (mcu) failed on model s 85d with 2-3k. 2018 models have this issue fixed supposedly, but models <2018 do not. Tesla should ideally upgrade all models if there is a solution.
Starting about 0700 mst on 13 july 2020, my 2015 model s 85's mcu began rebooting. The car was in motion on an arterial road at about 45 MPH with navigation active. When the reboot started, I pulled off the road into a parking lot. After the first reboot, the mcu appeared stable for about 10 minutes, then rebooted again. This time it was stable for about five minutes. Since then, it has been rebooting continually in a cycle of about 1 minute 45 seconds. Vehicle control and accessory functions (backup camera, air conditioning, navigation, radio, bluetooth, lights, doors, etc) are no longer usable.
Media control center turns black and wont allow me to operate the car properly. Verichle has done this on start up and while sitting at traffic lights/while driving.
The screens on the car regularly react sluggishly and sometimes lock up requiring a reboot. This can happen whether the vehicle is parked or in motion
Tesla media control unit ("mcu") is no longer operable (screen turns black and loses all functions). The tesla mcu is basically the car's central control system that allows you to adjust the headlights, the steering wheel resistance, the vehicle charging controls, the vehicle suspensions... Etc. The screen turned black, my turn lights are disabled (as shown in image, lights will no longer blink), my headlights are disabled, my airbag functions can no longer be switched to off when needed, the moon roof cannot be opened, the AC system along with defrost/cooling functions are all disabled and inaccessible. The vehicle dashboard displays "please wait while vehicle system powers up" for anywhere between 1 minutes to 4.5 minutes. The vehicle is not operable during the system power up when I enter the car. This issue appears to be connected with the mcu failure and have persisted and worsened in the months leading up to the complete failure on 7/16. I would have to sit in vehicle for 1-4 minutes, unable to drive the car because it is loading up. This shows that the mcu is extremely essential to the vehicle, and not merely a media unit as they have tried to convince with the name. It appears that the mcu fails after a number of years/usage due to the old chip that rewrites over repeatedly. The mcu is pre-installed to fail in all vehicles produced prior to 2018 in the model x and s. Basically this system will fail in every car at uses the old mcu1, and doesn't apply to vehicles after 2018 since the switch to mcu2. I reached out to tesla service center by phone (unable to access the tesla app due to the inability for app and vehicle to communicate), and they quoted a replacement of the same mcu (but with an upgraded chip) at the price of $1201, with a 3 week waiting period. The car is not inoperable for the next 3 weeks due to the lost of essential and safety functions.
Cars main screen went out, while driving on autopilot as the screen went black all of the sensors didn't work and car was accelerating without consideration for other vehicles. Turn signals didn't work and AC went out. Now tesla expects me to pay 2500 for their manufacturing flaw. They are well aware of their design flaws and it seems that every model s either had mcu issues .
