The mcu (main console unit) is black and wont turn on. Tesla is stating they want me to pay for the repair as it isn't part of the drivetrain. I cannot control certain things like charging and driving safety features without it.
2015 Tesla Model S electrical complaints
Page 7 of 10: complaints 161 to 190 of 269, newest first, as owners wrote them.
When we went out to our garage to drive our 2015 tesla model s 85d on july 9th, we found that the main screen had failed. The small screen in front of the steering wheel was still working, but the 17" screen was black. I tried three times to reboot that screen, but no success. I called the tesla service center and they had me hold the reset rollers down with my foot on the brake for at least two minutes. I did so, but no help. They will be sending a ranger out to repair the issue on 7-22-2020. I assume that this is another example of the tesla mcu failing, which will be pricey to repair. Luckily it was parked in our garage when it failed rather than out on the road.
The mcu1 failed (as per tesla diagnosis) and the car is disabled and must be towed. Car cannot be placed in tow mode, systems will not reboot, car does not power up. Vehicle was parked in garage from night before when car worked fine. Next am car was disabled.
Screen failure
My mcu stopped working and I was unable to use a lot of the cars functions. When my screen went dark I was unable to see any display of the reverse camera and was unable to adjust suspension settings. This happened as I put the car in reverse in my driveway with family members walking around the area. The car was towed to a tesla repair facility and I was told they were able to get my mcu working but the problem will likely return.
Media control unit screen went blank while vehicle was in motion. Vehicle still drives, but driver is unable to use navigation or media functions. No turn signal feedback. No backup camera. Worse, unable to control AC that was running at the time of incident. Air conditioning still runs after vehicle supposed to be stopped, draining battery. Vehicle had to be parked for 48hrs + with AC running constantly until brought to dealership. Service wants $1700 for a replacement, or $2250 for an "upgrade".
Mcu1 screen goes black, disabling climate control, headlights, blinkers, lock/unlock doors & trunks, auto pilot, tow mode, wiper service and other features that control the car. My car is due for ny safety inspection that it will currently fail. My car was on highway when it happened the screen froze. That was february 2020, this happened where bluetooth and music stopped responding while driving. I was at costco and after I loaded the trunk up, got in the car the screen was black and no backup cameras or blinkers, this happened while parked but I had to get it home using hand signals to get home. I had to drive it like. I had uploaded a picture of it in the tesla app and I can't retrieve it.
The vehicle had computer issues during oct10-feb1. Loss of connectivity, reboots occur while driving. No speedometer. No turn signal indicators, no parking brake ability, I parked vehicle feb1 for safety reasons. Attempted to get service. Vehicle by april[15] had gone from intermittent to permanent. No visibility of computer screen.no functions. No high headlights, just low headlights, no crash imminent buzzer, no autobraking. Drive&reverse only, steering different, slightly stiffer, no hands free phone & no GPS ability. Easy to get lost or confused as to where to turn or whether to turn or go forward. Arm out windows for turning, reduced speed controls. No lane departure buzzer. Changing lane refusal w adjacent car present in lane inoperative. Comp. Not covered by warranty, while under warranty, the repair was declined, stating 'it must be completely dead before it can be replaced under warranty' by apr15 comp. Was completely dead but I had declared warranty inadequate upon first refusal to cover it, july, no parts available, so many weeks of waiting. Dealer unable to find an upgrade part to sell to me. Waiting for a $2500 install of a new part that I am willing to pay for but cannot procure quickly enuf, no matter what. Driving without control of headlights or without turn signals has been curtailed but for emergency food procurement. Doctor visits, mask&glove replacements for the covid situation requires those. I have been lucky I guess that this has happened permanently at home & only a few sudden times temporarily on the road. The failure was intermittent, denied replacement requests & finally failrd entirely, now all must wait while unable to safely drive much of anywhere. Car not sale-able, nor does it cease dropping in price every month while I await a fix. Rental is expensive. Insurance gave me first 30 days, those over now. Susp. Insur. Thank you.
The center screen of our car suddenly went blank. I used the app from inside the house to turn on the climate control. We went to the garage and unplugged the car from the charger. I received a notification on my phone that the car was unplugged. Upon entering the car we found the center screen to be blank and unresponsive. We attempted to reboot the screen but nothing happens. The climate control was stuck continuing to cool the car. The car will no longer charge properly. The app will no longer connect to the car. We pulled the fuse for the touchscreen to get the climate control to turn off. The car is not drivable. Public information indicates that the issues is a failed emmcdue to excessive writing to the chip due to tesla's design.
Mcu failure. Due to failed mcu there's no backup camera or any of the safety features. Every tesla model s/x built between 2012-2018 goes through this issue.
The touchscreen in my 2015 model s has completely failed. I've attempted all of the resets that tesla recommends to restart the system to no avail. The car is nearly useless, none of the electrical features of the vehicle work, including heating/air conditioning, charging features, audio or turn signals. The car worked fine yesterday, today the screen was just gone.
Tesla model 2015 model s mcu keeps failing. The mcu failed twice in 1 year. Tesla service center schedules an appointment, simply resets the system and sends you back home. Before failing , the system shows signs of slowness like delayed start ( note* car can still drive without starting an mcu but multiple things such as HVAC / backup camera wont work )
The main vehicle screen stopped working. Complete loss of rear camera image display when reverse gear is selected, resulting in reduced rear visibility when backing. No control over battery charging commands. Many times when I place the vehicle in reverse the camera would not display a rear image. Now my screen is completely black and nonreponsive
Center screen went out, no phone app connectivity, unable to turn vehicle on, unable to charge vehicle. Completely unresponsive.it was in the garage thankfully, needed to be towed out and flat-trailer-ed to service center
Media control unit (mcu) failure
The 12v battery on our 2015 tesla model s started failing last november. We were assured that tesla that it would be safe to drive until they could replace the battery (which took about 2 months). We've come to understand that this is far from accurate. After that, our mcu (the main computer in the car) failed. This is apparently a well known problem that tesla refuses to fix. When they replaced the mcu we immediately started having issues: 1. The emergency flashers did not work. 2. The computer logs were not available to tesla to diagnose issues or recover our car if it was stollen. 3. The fog lights stopped working 4. Glove box would not open 5. Screen now has noticeable flicker 6. Car now has charging problems. The issues with the emergency flashers, fog lights, and glove box were able to fixed by a different service center the same day (although I had to drive approx. 30 miles to get to a different service center). The logging issue took about a month or two to fix. The screen flicker and charging issues where the car randomly switches to a different charging level while driving or charging without any error messages, is on-going. I've been back to tesla over a dozen times, and they ike to charge $100 every visit "under warranty."
Loss of turn signal noise, headlight control, rearview camera, climate control, seat memory, garage door opening capability, navigation, emergency braking, and difficulty charging the car. This occurred gradually over the course of a couple of days and has left the vehicle inoperable without headlight control, auditory warnings, and rearview camera. This is caused by a failed emmc chip on the mcu in the car. It is a well known problem and not covered outside of warranty, despite it being guaranteed to fail sometime between 4 years and 5 years of age. (warranty up after 4)
The tesla media control unit completely failed on 7/5/20 after being unable to turn back on. The vehicle was stationary and was parked on the street. Due to the failure of the media control unit, the systems such as the air conditioning, backup camera, controls, etc were unable to be controlled which posed a significant safety hazard.
I went to tesla service center on 6/26/2020, notify them the problem for slow response on the touchscreen and also rattle sound coming from the steering wheel area, tesla stated the steering buttons need to be replace and the touchscreen is due to the older chip on the model, so it's normal. I picked up the car two days after after the replacement, on 7/4/2020 while I m charging at the tesla super charge station the car screen is complete dead, I can't play radio, no navigation, signal lights not working and back up cameras failed etc. I went on research and it seems like this issue is known now with the federal safety agency and is investigating. Today tesla said my mcu needs to be replace.
My media control unit (center console screen) stopped working. Screen went black and nothing outside of throttle/brake/turn signals worked. All functionality controlled by the mcu stopped working. The car started taking about 2 to 3 times longer to boot up and after a day or two, the screen stopped working completely. After dropping off at the tesla service station, the technician informed me there were mcu issues with the model s from 2016 and earlier due to the memory capacity of the chip used.
With the recent news on the federal safety agency investigating tesla model s touchscreen unit problems, I like to add my experience for the record: on 01/31/20, my computer screen died which limited the car's functionality (e.g. No HVAC, radio, bluetooth, etc). On 02/06/20, tesla came out to inspect my car, and verified I needed to replace the computer. The technician admitted how bad the problem was for productions with mcu v1 computers. But before the technician left, he performed a battery disconnect which made it worse. Now the car was not able to charge which forced me to take the car immediately to tesla to replace the computer. On 02/19/20, the replacement computer was installed at the cost of $2,122.50. To add, tesla would not let me keep the original computer without an additional core charge of $500. 12 days later on 03/02/20, tesla announced an infotainment upgrade on the backs of these ongoing issues: https://electrek.co/2020/03/02/tesla-mcu-infotainment-upgrade/ https://www.tesla.com/support/infotainment
Main computer screen failure. It's been down for over 2 months waiting on parts. No eta
The main screen, mcu, on my tesla model s, 2015 70d began rebooting during driving. On saturday, july 4th, 2020, the car would not start at all. Tesla customer service coached me on getting the car to work without the main screen, however it is not safe. The brake lights, signal lights, rear camera do not work, verified by my spouse. Further, most of the other controls, e.g. De-fog, air conditioning, roof, etc, do not work. The re-booting of the screen, where it would blank out without warning, and eventually come back later, occurred while the car was in motion -- very distracting. At this point, the main display, or mcu, is "bricked" -- it won't display anything at all, so that has happened when the car is stationary.
The vehicle was parked and locked. When I unlocked the car and opened the door, the infotainment screen on the tesla will not boot up. As a result, the side rear view mirrors will not unfold and the rear view camera cannot be viewed. In addition, the climate cannot be adjusted. I attempted to reboot the infotainment system several times and locked & unlocked the car, but the infotainment screen did not turn on and the side mirrors will not unfold.
My mcu has failed for the 3rd time rendering the car w/o turn indicators and other features.
My current media control unit (mcu) stop working. I not longer have navigation, AC and I cannot control unlocking of my doors etc.
My tesla mcu1 screen/memory failed and had to be replaced at my expense. $1600. When that happens, turn signals, climate control, and wipers are inoperative, making the vehicle unsafe to drive.
Main control screen (mcu1) went black, disabling access to most controls including defroster. Had repair done (out of warranty) at a cost of $1800. Problem is poorly designed electronics causing failure of memory chip in unit because of too many read/write cycles. My understanding is thousands of 2014-2016 cars have suffered this problem in the last year.
The touchscreen on my car has permanently turned black therefore I have lost the rear camera image display when reverse gear is selected. As a result, I almost ran into a shopping cart while I was backing up yesterday. What is frightening is that next time, it could be a small child that I don't see and run over. The failed touchscreen also means I no longer have fan or air conditioning which means I have to drive with my windows down, even when on a highway. In this time of covid, I was terrified when a homeless man put his head through my window to ask for money while possibly contaminating me with a virus yesterday. It just is not safe to drive around with the windows down in some neighborhoods. Also there are days in the bay area when there is a high pollution index, I do not wish to breathe unfiltered air because I have to open the window because the fan cannot be turned on. According to the tesla repair shop, the failed touchscreen is a common problem on the older model s that requires owners to shell out thousands of dollars to replace an mcu that has failed prematurely. I do not feel I should be financially responsible for the mcu replacement and that there should be a product recall.
Emmc failure. Main screen fails to display making the vehicle inoperable.
