My screen turned blank and there was no way to see the rear view camera, the turning signal, to set the temperature control due to a known defect of a memory chip. I took the car into the dealership with history of multiple black outs, and they refuse to replace it although tesla website said that they would

Brought the car in for service at the macadam service center in portland, oregon on october 29th due to mcu issues; this was before any notice had gone out! I was not even aware of the issue at this time. It was rebooting, very sluggish, gets 'lost' ie keeps outdated information etc. This is obviously the 8gb memory device issue. After a 40 year career as an engineer and venture capitalist in the it industry I know what memory failure looks like! I was told there was no issue and that it was safe for me to drive to sf the next week. I had major issues on the trip. The system rebooted a number of times, was extremely sluggish and had data update issues. Specifically: -depart lake oswego at 5:30am on 11/23. Soon thereafter the left front fender camera informs me it is not working. It does so repeatedly every minute or so for a long time. Then all cameras inform me they are not working. I stop, twice, clean all the cameras and it does not resolve anything. I give up on the cameras working and stop using cruise control -at 12:31pm in the shasta area streaming fails and then the whole mcu shuts down. While driving in the rain I am forced to react and open windows to keep the windows from fogging up while driving at 70mph. Othis is a serious safety concern. I have updated my the federal safety agency complaint to include these serious safety concerns. -7:48pm 11/23, while supercharging in emeryville the mcu completely froze. I was had to force a reboot. 2nd reboot in one day -5:28pm 11/24 mcu crashes while driving again! How do you not understand the safety implications of this?! This is the 3rd crash in 2 days!. I will make an appointment and expect you to fix this issue. I will continue to update my the federal safety agency complaint regarding these safety issues until tesla resolves them.

This is my second tesla. I've had noises in suspension and have been told it was a control arm and paid for it. Noise immediately returned. Later told its stabilizer. That was on first tesla. Media control unit constantly failed. Second tesla - [xxx]- suspension problems. Something feels like it will pop of I turn wheel too far and the brake or something makes a loud noise when disengaging. They say they can't duplicate but it happens every time I brake or release hold. My mcu is failing on this car. They replaced the ram but it still fails. Gps is barely functional and my reverse camera will not appear many times. Sometimes my car won't charge. They ignore and say it's normal. Mcu needs replacement. I spoke to a tesla employee and I'm sure you know, but he says they only wipe and recycle the ram used on the mcu. That would explain fast failures again. They are trying to stall our warranties out to force purchase of the second mcu that they claim is the best solution. They are not going to stop these behaviors if we aren't protected. I have video I can share. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
My mcu is continuing to power off while I'm driving and the small screen takes longer to boot up. This also happens when surfing still before I start out of my garage.
Tesla mcu fails intermittently- rendering autopilot and all safety features associated useless. Also causes extreme scare to driver when failure occurs, as they believe car is off/not working. Occurs on numerous occasions, both on startup and while driving.
Experiencing regular blackouts of main screen forcing me to stop driving and wait for reboot (unless triggered manually as per tesla sc advice). Complete blackouts have happened regularly about 5-7 times over the last 2 months, latest being nov 17 at 6:30pm. Tesla service center ran diagnostics on latest occurrence and claim firmware issue as opposed to emmc fault as per extended warranty communication received from tesla about a month ago. According to sc diagnostics showed 'mcu using a high amount of resources' at the time of failure and referring to firmware issue. No updated firmware eta given. Asked about characteristics that distinguish mcu failure from firmware issue with no response from sc. Seems like tesla is avoiding an underlying mcu fault by claiming firmware. I am fine with a new firmware to fix the experienced problem. However, I am not satisfied with justifying fault with firmware issue but no solution. This must be a well known issue at tesla which should have triggered an immediate firmware solution. No firmware solution to me indicates an underlying problem. With the extended warranty on the mcu it is clear that tesla has been forced to recognize the problem, however, without actual solution for customer. Blackout happens while driving. Investigation of firmware issue related to blackout problem needed and furthermore, what distinguishes characteristics of blackout generated by mcu (emmc) and firmware issue.
Tesla onboard computer crashed, no back up camera when reversing, indicator lights didn't work, no navigation, radio, bluetooth, unable to control air conditioner. Tsla upgraded "daughter board" a few months ago, but it happened again. Taking it to service in dec. Hope they upgrade the chip instead of installing the same old emmc that has been creating the problem.
Tesla model s 2017 mcu 1 failure. Repeated black out of mcu during driving and delayed start of vehicle and 2 min 30 second delay in AC/heat start up from overnight parking. Mcu nvidia tegra 8g was replaced under warranty with nvidia tegra 64g mcu. The same issue is of recurring; black out of mcu during driving lasting 20-30 seconds that renders turn signal audible notification mute and back up camera inoperable; delayed start up of vehicle is better now but not completely resolved. Request for mcu 2 intel upgrade denied as is a purchasable upgrade.
While in motion, the large screen goes black and all audio is lost, even the sound the blinker makes. I can not restart it, it just takes time and usually restarts itself. But whenever it restarts itself, audio still does not work. Sometimes it never comes back on during the drive. It appears to be the mcu and emmcu chip. Apparently tesla knows about this, I have had my car in for service and have asked that the chip be replaced. They have so far refused and keep diagnosing the issue with no resolve. They want me to upgrade to an infotainment system, which they say will fix the issue, but thats $2500.
Touch screen is completely black multiple times per week. Usually at beginning of trips, but occasionally suddenly occurs in the middle of trips. Black out can last upwards of 10 minutes (per smartphone stop watch). Touchscreen blackout limits access to fog light controls, back up camera, garage controls, passenger airbag status indicator, and all audible warnings including emergency brake alert and turn signal noises. The vehicle is covered under tesla's new extended warranty. I requested service on 10/17. Was scheduled to bring car in on 11/12 (next available). They said it was done on 11/13 after only completing a diagnostic and a firmware flash. No hardware modifications were completed. Same symptoms reoccurred on 11/23. I contacted them that same day and they gave me an appointment of 12/18. Today (11/24) they contacted me to recommend I cancel the appointment as the issue is (they say) software based and they "found no issues with the hardware" via remote diagnostic. Video link below of a recent 7 minute black out. Https://photos.app.goo.gl/3bdbafq7ylvjtxfu7 I have attempted multiple forms of reset/reboot when this occurs with no notable improvements.
I have reached out to tesla to fix the problems I've been having with my mcu, multiple times. They always try to come up with some excuse not to replace it with the mcu2. One service tech actually told me that my problems would be solved if I purchased the 'infotainment upgrade' that gives me the new mcu. Another tech told me that the mcu isn't covered under warranty at all. I refuse to pay $2500 for an 'upgrade' to fix my problems, when this should be their responsibility. I have had multiple camera failures resulting in driver aid functionality being reduced or eliminated all together, and the only way to fix it is by recalibrating the cameras. I have had door handles stop working at random times, that end up requiring a full reset of the car to repair. My central screen crashes/reboots at random, whether or not the vehicle is in motion. When that happens, none of the controls on the touchscreen are usable, and some of those are what I consider to be essential controls. For instance, climate/defogging ability is reduced or eliminated. I have been in for service multiple times now, almost all of the appointments were for things controlled by the mcu. They also have told me that my vehicle doesn't qualify for the emmc warranty repair/replacement, because it only covers 'end of life' components. The vehicle is still under the full warranty as well. I have another outstanding service appointment scheduled for december 1st. I have requested a new mcu again, but will not be surprised if they deny me. I have many photographs and screenshots as evidence.
After running errands, I park by my front door to unload my car. After unloading, I get back in to park it in my garage only to find my center screen is blank. I'm unable to use the functions controlled by it (rear view camera, garage door opener, etc.) until the reboot process completes. Tesla does not consider this a defect and will not repair it under warranty. This happens nearly everytime I follow this process.
For about a year I have experienced spontaneous failures of the touchscreen, losing all climate controls and audible signal alerts while driving while the system reboots. The screen eventually goes black before the system reboots. I have repeatedly tried and failed to get tesla to fix it. They keep telling me it will be fixed by the next software update, but that never fixes it. Also, the voice recognition and nav systems don't work 5 out of six tries, which is distracting while driving. Tesla also claims that will be fixed by a software update, but the updates never address it. I just learned about the high failure rate of the memory when tesla said it was extending the warranty on it. I asked to have the memory replaced under warranty, but tesla refuses to admit that is the problem and says the software fix is coming by the end of 2020. I have experienced all issues while driving on freeways, surface streets and sometimes while parked.
Tl* the contact owns a 2017 tesla model s. The contact stated that the media control unit was inoperable. The contact stated that the failure was intermittent. The contact stated that after extensive research, he was concerned about a complete and permanent system failure. The failure recurred three times. The contact contacted tesla (1901 del monte blvd, seaside, ca 93955; (831) 264-6896) and was informed that unless there was a hard fail, the dealer was unable to repair media control unit free of charge. The contact stated that the failure was related to a voluntary repair however, the hard failure as indicated by the dealer, was necessary for the repair. The manufacturer was not made aware of the failure. The approximate failure mileage was 50,000.
The mcu screen goes blank repeatedly. It requires a reboot. When this occurs loss of numerous vehicle functions occurs which creates safety issues. Control of defogging, rear back up camera etc are some of the last safety features. Currently has only occurred in stationary vehicle
The mcu touchscreen fails constantly causing no access to rear view camera, AC controls, navigation, and loss of preset settings for mirrors and drive seat position. Reboot takes over 5 mins while car is in operation to no AC working. Both headlights have been replaced over 10 times due to burned out daytime running lights. I have paid for the last replacement only for it to fail again.
2017 tesla model s. Center screen freezes up and dash lights go bright to dark. Issue; when center screen locks up you can't use the following- defrosters, air conditioning, heater, garage door remote, navigation, back up camera, auto poilet warning goes on and off with out me touching it.. Very dangerous and scary . I had it in twice for the same problem and was told it was a simple soft wear update. Finally have an appointment but it took over two weeks. Now I am told that if there was an upgrade I need too pay out of pocket for the companies faulty issues. Seriously! This happens moving and stationary. Happens multiple times weekly
The mcu touchscreen is requiring rebooting on an increasing basis, 4 or 5 times a week. The rebooting can take at least 5 minutes. I feel it is a safety problem since the vehicle is non-operational during this time.
Mcu still failing after having it replaced.
Central screen (media control unit - mcu) continues to shut down and restart which causes loss of air bag, climate (including de-fogging), rear camera as well as media controls/GPS. Tesla repair indicates that it is a defect that can only be fixed by upgrading to their new mcu2 at a large cost. Replacing with same system will not fix issue. This restarting/rebooting occurs when driving and when idle with no warning. Tesla claims it does not affect driving but it completely shuts down ability to charge, use climate control(including window clearing) and safety controls like airbags. This happens approximately 1x daily when driving car starting after tesla installed something related to full self driving option.
Apparently a total failure of the 'daughter board'. In this instance the car was parked when it happened. Got into car and at first wouldn't power up as normal. Touchscreen, including all controls for vehicle, would not start up. Climate started up but could not be controlled. Car would start but blinkers didn't not work. Something similar has happened on perhaps 10 or more occasions in the past, though usually could be fixed with a hard reset. In at least 2 instances the AC has stopped working midway through a drive (through over 100 degree weather with elderly persons in a very long drive- very unsafe)
Media control unit(mcu) fails. Car has no audio(radio or navigation), and cameras malfunction. Screen refresh extremely slow. All causing safety issues and distractions to the driver. A reset temporarily fixes, but resetting every time I get in the car is impractical. Tesla service requested I remain patient until a firmware modification is prepared. They did not offer a timeline. I understand the mcu failure is common and currently under investigation by the federal safety agency
Common complaints regarding main computer. Takes longer every day to start, many delays with everyday functions, blackout/restart during operation, etc...
My 2017 model s has had issues with the mcu whereby the center screen would restart while driving. Many occasions I would be backing out of my garage and center screen would restart or go black for extended time resulting in no back up camera or turn signal access. Earlier this year before covid, I backed out of my garage to go drop of my kids at school. And, the center screen was black for the whole trip - no access to back up camera, turn signals, or defrost controls.
Tl* the contact owns a 2017 tesla model s. The contact stated that the hardware computer failed. The contact stated that the vehicle was repaired once for the failure however, the failure recurred. The vehicle was taken back to the same dealer tesla service center - latham (326 old niskayuna rd, latham, ny 12110) however, the dealer refused to service the vehicle for free. The contact drove the vehicle to the dealer without the indicator lights or windshield wipers operational. The manufacturer was made aware of the failure but, offered no assistance. The failure mileage was approximately 61,000.
There are challenges with the mcu1 and its integration with fsd hardware #3. This manifests as freezes on the central and drivers displays until the cars mcu does a full restart(speedometer is not affected). This restart can take as little as 5min or can stay off for the drive until manually force reboot initiated. During the freeze I experience loss of passenger airbag(warning comes on, I cant tell if other airbags are affected). The climate control system turns off no A/C or heat is available. Sometimes auto pilot is affected, so I would assume emergency braking is affected because its the same system as auto pilot. The odometer is does not record miles if this happens while driving. No back up camera is available. These issues have increased since I had the hw3 upgrade here is a website that talks about this issue https://tesla-info.com/blog/tesla-mcu1-emmc-failure.php https://teslamotorsclub.com/tmc/threads/joe-rogan-vs-mcu1-hw3.203776/
The defective mcu went down and what is not being properly reported, especially in this pandemic world we now live in, is that besides the entertainment, the air conditioning (and viral hepa filter), the suspension height, the steering and acceleration properties, nearly everything is no longer accessible when the mcu fails because to the driver, these things can only be accessed and manipulated through the center console, which is in permanent shut down mode. Look, I perform fmea analysis for a living. This is a single point failure being caused by the poor decision to select an mcu chip that has a limited number of data writes to the memory, and that cannot be cleared out by any system designed into the car. Mine just failed last week and my car only has 30,000 miles on it. Tesla claims that they only warranty the entertainment system for 25,000 miles. The problem is that they've integrated the mcu and emmu as the single source of operations for all other vital systems in the vehicle. This is completely insane and is without a doubt a safety issue, as it was 90 degrees the day my mcu failed and dangerously hot inside my car, even with all windows down, which only got worse because there is so much thermal loads created by the battery, normally protected by the overheat sensors & fans, that are now not operating properly thanks to the mcu failure. It also important that you understand the most of the need to write to the finite mcu & emmu memory is caused by tesla during their frequent software updates. Mine is a p100d ludicrous + and cost well over $100,000 when new. Tell me what other manufacture would be allowed to get away with designing a single point of failure that effects nearly every system including safety features, and then say its only covered for less then the time they know the first failure will occur. Criminals and make them accountable now please.
Mcu is failing preventing safety features and normal functions such as turn signals, AC, radio, nav, etc. Happens while driving.
Main computer experienced the emmc failure which is widespread for this model and year, amongst others. I could tell it was imminent for failure, however we did not realize the vehicle needs this computer for turn signal control. Thus, my wife drove home from work with a dead computer and thought she has turn signals when she did not. Fortunately she made it home safely. We have not driven it since we realized this safety concern. Fufthermore, the backup camera also is unusable in this state. I went ahead and scheduled for the newer computer (without this known issue) to be installed as soon as I saw the symptoms of imminent failure, but it died a couple days later, and is currently not safely drivable while awaiting the part.
Completely black mcu screen that does not turn on even after a reboot. No AC, no warning sounds, and most importantly not being able to use turn signals when the car is both stationary and moving.
