Mcu failure, when backing up the rear camera does not turn on, center screen console has gone black and will not reboot despite multiple attempts to do so. Seems like a mcu failure. Car is essentially very hard to drive - hard to back up - rear camera is not functioning, has become a safety problem. Has been intermittent over last few weeks, now permanent.
2015 Tesla Model S electrical complaints
Page 5 of 10: complaints 101 to 130 of 269, newest first, as owners wrote them.
The media control unit on the car failed and needs to be replaced. In addition to all controls operated by the touch screen, including the back-up camera, the car's blinkers do not work.
The driver's display panel which display the speed and other important information about the state of the vehicle is bubbling and making it difficult to read the current speed. This is a common problem with this model according to the owners forum. Even though this is a common safety problem, telsa has not issued a recall for this problem.
Issue with the mcu1 or infotainment system failing. This resulted in an unsafe condition while using auto pilot the system froze and shut down during the operation of the vehicle. The ai cameras, radars, trip routing are all controlled by this infotainment system and all of them shut down at once while the vehicle was moving. This could have easily resulted in an accident as features like assisted lane change, collision assistance, summon, auto car distance, auto pilot 1.0, stop sign and stop light sensing all rely on this computer which immediately stopped without warning. Also, all video provided for the back up camera now no longer works or collision detection from the radars while back up completely stopped which is a safety issue when pulling out. When asked the dealership tried to up sell me into the next mcu for 2500 dollars to fix this 'known' safety issue. This allegedly happens because of the massive crowd error logging that tesla uses in its flash memory (which can only be over written so many times) to better its products but the user is unable to shut the logging off. This forces an eventual indefinite failure. The individual user had and still doesn't have the ability to shut this off. Tesla is forcing its users to pay for an upgrade after the memory burns out because of a data collection effort that is company imposes and by consequence robbing its users of important safety features in the mean time. When this is combined with real ai that the user needs to drive it can even cause an accident in real time.
The main center screen computer began degrading in performance over time (causing more driver attention to be diverted away from driving to deal with functions it controls, as it was laggy and not very responsive). Then, one day, I got into the car to go somewhere and wasn't able to boot the main computer/screen at all. In addition to everything it controls no longer being accessible or working (e.g. Climate control, manual headlights, dome lights, anti-theft alarm, power steering strength, suspension height, etc.), I also found that I no longer had working turn signals and had to use out-the-window hand signals when I drove to the service center for repair.
Complete failure of mcu when starting the car after only 31k miles, causing blackout of al screens, driver information, controls, etc. Tesla had me drive it to the service center in that condition and charged $1,462 to replace without any indication that it is a known design problem. (note incident date is approximate.)
While stationary, middle touch panel (mcu) on my 2015 tesla model s 85 (~60,000 miles) started freezing up between vehicle controls (lower left 'car' icon) and garbling screen when trying to switch between them, a couple of days ago. I noticed first symptoms about a week ago when percent charged on the middle touch panel didn't update together with the instrument panel while supercharging. Now I have to scroll-wheel-reset my car twice a day: before driving to work (it's frozen in the morning) and again before driving home from work (frozen again in the afternoon). An additional symptom manifested itself today: my rearview camera started getting a nasty 'gray veil' over it so you can't see anything; it seems to keep appearing and disappearing.
The tesla's large screen quit working. These are controls that power off the vehicle, turn the defrosters off and on along with the climate control. Control steering modes. Control back up camera, control lights. From the reading I have done it is called the mcu. It partially went out while I was driving, it came back on and then it died while I was working and I found out about it when I started the car after work.
Mcu failure including black screen. No touch screen, climate controls does not work, turn signal not working. Can not control head lights. Charging not responding. Navigation not working. Back up camera not working.
Mcu (media control unit) blank. Wont reboot. Indicators dont work anymore.
Mcu failure in need of replacement screen intermittently goes dark, app no longer communicates, controls glitchy
Turn signals all failed, rear camera failed, touchscreen interface failed
The mcu (version 1) of my car stopped functioning while parked and needed to be replaced. This is a known issue (emmc failure). The car was still operational however the following safety issues resulted from the mcu malfunction: - turn signals and audible chime both beame nonoperational - reverse camera beame nonoperational - high beam headlights beame nonoperational - lane departure warning may hae become nonoperational - climate control stuck at one level - instrument cluster lighting setting became unable to be changed additional issues resulting from the mcu1 failure: - all systems and settings accessed through the center console screen beame unaccessible - navigation system beame nonoperational - audio controls beame nonoperational - auto-pilot (lane assist) beame nonoperational - alternating current (AC) charging speed reduced to 2kw - remote access via smartphone beame nonoperational
Tl* the contact owns a 2015 tesla model s. The contact stated that there was a loud sound coming from the engine while the vehicle was plugged up and charging. The contact disconnected the charger in fear that the battery or the engine may explode. The contact stated that the vehicle failed to be fully charged. The vehicle was not diagnosed nor repaired. The manufacturer was contacted and notified of the failure. The failure mileage was 65,874.
The mcu that operates the car failed.
When turning on my vehicle, I noticed bubbles had formed at the top right edge of the instrument cluster screen. After a bit of online research, it turned out that this is a frequent problem with the instrument clusters in tesla model s's and x's. If I had let the problem progress, the liquid in the screen would have eventually flowed over other components behind the dash and started dripping out the bottom of the dash onto the driver's legs or carpet. Tesla charges about $1400 to replace the instrument cluster screen with an identical unit that may develop the same problem after about 4 years service. I opted to replace the screen myself for about $300 for a new oem screen sold by an online entrepreneur, and a few of hours of work to disassemble the dash, remove the instrument cluster computer, replace the screen, and reassemble the dash. Tesla is aware of this problem. Tesla spec'ed a screen that doesn't always hold up to the climate rigors of a car interior. This may not warrant a full recall, but tesla should offer an extended warranty for this component, and perform the repair at no cost the the owner
While backing out of my driveway, I noticed that the center screen (mcu) was not turning on. After trying several system resets, I gave up and used our other vehicle for the trip. After scheduling a service appointment, I was contacted by a tesla support to further diagnose the problem before the appointment. The memory chip (emmc) in my vehicle's media control unit (mcu) has failed, which prevents the mcu from functioning. The mcu controls many aspects of the vehicle, including lighting, suspension adjustment, climate control, navigation, accessories, entertainment, vehicle status, etc. Without the mcu, the vehicle is still drivable, but in a seriously compromised state. The backup camera is not available, the climate system is off and can not be turned on. Various audible warnings can occur spuriously, like the chime for an open door or hatch, and obstacle proximity. Tesla is aware of the emmc failure in their earlier vehicles (those equipped with mcu version 1, like mine), and offers a to repace the mcu with a refurbished unit for $1100, or an upgrade to mcu2 (which includes the instrument cluster computer/screen as well) for $2500. This serious issue is due to a design deficiency of the version 1 mcu. Tesla should order a recall of all affected vehicles and do the repair at no cost to the owner.
The main computer screen (mcu), on my 2015 tesla model s went completely black while driving in the city. I am not able to read or change any controls on the car or communicate with the computer program.
The emmc chip in the media control unit failed resulting in the large touch screen no longer working. I lost control of the turn signals, climate control, rear view camera, charging, navigation, and audio. It is the same problem described in your pe 20-010 investigation document.
Touch screen blank, mcu failed. No rear backup camera, turn signals, air conditioning. Slow to start, creep mode failed among other problems.
The center screen/mcu suddenly stopped working (went black). Trying reboot/standard troubleshooting steps has not yield any success. After a few days, many other features, including blinkers (excluding emergency/flashers lights, which activate but lacking sound) stopped working. Made an appointment through tesla app, with description of the issue, on 6/24 for 6/30 (earliest available date); on 6/26, I received an email that the appointment had been moved to a service center for 7/7. On the same day (6/26/2020) and about an hour after initial rmail, I received another email that my appointment had been canceled "per your request", but I had not requested a cancellation. I visited tesla's service center in san diego - miramar between 7/7-7/10 to inquire about service cancellation and request a service for my car, but I was told that they had cancelled my appointment due to parts unavailability and I would be contacted later once parts become available to schedule another appointment; however, the service center refused to look at/evaluate my car whatsoever "due to covid" and told me that based on other situations, they're very sure the mcu needs to be completely replaced (~$1500 out of pocket cost) but they do not have a replacement yet; I explained my blinkers and many other safety features (rearview camera, climate control, "auto-pilot", etc.) also not working and they mentioned those should typically continue to work after a mcu malfunction but they will not take a look at the car until they receive replacement mcu. It's now past 8/3 and I still have not heard back from tesla on path to resolve this issue/new service appointment. It's also worth mentioning I have no way of knowing car's current mileage (last update on app from 6/23 reads 103,683 mi) or outside temperature due to this issue as well.
The mcu failed while we were traveling, which basically locked the climate control, access to suspension, speed control, autopilot, navigation, radio, turn signals, and back up camera.
My media control unit failed in the vehicle making it unsafe to operate as the turn signals, defrost, headlight controls, among many other features of the vehicle were no longer accessible or functioning.
Tl* the contact owns a 2015 tesla model s. The contact stated that upon starting the vehicle, the mcu screen malfunctioned and went into a default mode. Due to the failure, the contact was unable to use multiple safety and electrical features used to safely operate the vehicle. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was 108,000.
The touchscreen for my 2016 tesla model s has become dead and is completely blank. I searched online and found that it's a fairly common problem with 'older' tesla model s and it costs upwards of $2000 to replace the mcu. I also read online that the federal safety agency has apparently started an investigation already. Please count me in for any support documents etc needed. I shouldn't have to pay for such a expensive repair for an electronic part suddenly dying on me in less than 5 years after purchasing the vehicle. Please help!!!
The screen does not turn on. Mcu has failed. Will not be able to use rear view camera, defrost function(esp when raining, this is a big safety concern with not having visibility), can not turn off AC(runs while car is off), rear back up camera does not work. Can not use the tesla phone app to use the functions, can not set charging. Range. The federal safety agency has opened a investigation in june 2020 and is on going.
After we returned from our summer home, I tried to drive the tesla. The main screen did not light up but I figured that a normal reset would fix the problem. As I drove, I attempted a reset but the screen remained black. I also learned that the turn signals would not work including the cruise control, windsheild wipers and headlight high beams. Worried about other problems, I returned home and have not driven the car since. Over the summer there had been several updates to the cars firmware and I was looking forward to the improvements. Prior to that. We were driving with other members of the family, all with the tesla app on their phones. The car went into "limp home" mode on I-95 and would not respond to numerous attempts to remedy the problem. The seat heaters would turn on and off, the doors would unlock and the entire car seemed to have a mind of it's own. I asked everyone to turn off their phones and the problem disappeared. Tesla service said they'd never heard of such a thing.
A couple of weeks ago, touchscreen/media control unit become black and my 2015 tesla model s lost rear view camera functiontionality along with other things.*dt tesla suggested me to do soft/hard reboot the system but it didn't do anything. Then, I was suggested by tesla to visit the service center and replace the mcu or upgrade to mcu2 at my own cost. Losing rear view camera functionality is a big safety issue and it looks like I am not the only one. There is an open investigation and it looks like emmc memory wear-out is suspected as a cause.
Tl* the contact owns a 2015 tesla model s. The contact noticed that the touchscreen was inoperable. The vehicle was taken to tesla service center (1580 church st, decatur, ga 30033) where it was diagnosed that the media control unit needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 34,270.
Screen went black. No navigation. No radio. No bluetooth. Mcu1 is out.
