Equipment Problems of Audi A4 - part 1

My car's mmi keeps restarting while driving which affects the rear view camera and while backing up it can restart and go completely blank. I feel this puts my safety at risk while backing up. It also shuts down my bluetooth to my phone which can be a hazard while driving. I have called the dealership but they will not do anything without a large diagnosis fee which I cannot afford. They have said there are no recalls against it. No warnings prior to the failure and the failure happens every time I drive it, including multiple times per use.

The instrument cluster has failed per the recall 90vc. Audi issued the recall for every model made in 2021 with the exception of the a3 and A4 and I believe this was a mistake as my instrument cluster has the same failure.

My 2020 Audi A4 infotainment mmi keeps rebooting and takes over a minute or so to load back. This has been happening recently and I have rebooted the system and followed the Audi/reddit forums to seek any help but no resolution. It seems most of the 2020 Audis are facing similar issues. This issue is concerning and needs immediate attention since I have had instances where I lost backup camera while backing. Losing navigation capabilities or backup camera feature while backing up or driving has jeopardized me couple of times since I had to fumble and hit brakes as I was almost handicap momentarily. Audi is aware of this issue and have had issued TSB in 2020 which is attached here, but no recall was ever conducted which they should as this now an industry wide problem. Also, I got to know that s they have issued a 2021 mmi recall affecting over 44k cars but not 2020, which is very surprising. Based on forums and other users it seems the firmware version 3243 need an overhaul or even mmi module replacement if firmware update doesn't fix the issue. Request the authority to investigate this known issue for 2020 car line with similar intensity as this a widespread safety hazard. Mmis usually incorporate other modules as well so there is risk for adas failures or parking aids.

Multimedia infotainment system spontaneously reboots causing loss of cameras andcollision avoidance features and requires the driver to re-enter log-in information such as pin #'s. This is a known software fault that should likely be elevated to recall status.

The multi media screen is turning on and off repeatedly and will not stay on for more than about 2 minutes. Blacks out reverse camera as well hindering the safety of reversing. Makes the reverse un usable most times.

Mmi constant rebooting - follow up my 2020 Audi A4 quattro's mmi system constantly reboots (~60 seconds), causing the screen to go black/blank. Component failed: mib3 infotainment software. This persistent issue leads to reboots and loss of digital display. System available for inspection. Safety risk: significant, recurring hazard. Critical safety features are inoperative for ~1 min during reboots, including: rearview camera (backing/parking safety) navigation communication no manual bypass exists; driver loses vital visual information problem confirmation: consistently reproducible. Dealer proposed costly hardware replacement with no guarantee, contradicting manufacturer guidelines for known software issues. Symptoms: continuous black screen, Audi splash, then re-initialization. Problem worsened over weeks. Manufacturer's knowledge: extensive owner research (audiworld, reddit) confirms this as a widespread, documented mib3 software defect for 2020 Audi A4/a5 models. Audi's own technical service bulletins (tsbs) address this: TSB 2069112 (mib3 improvements) TSB 2067021 (mib3 malfunctions) these tsbs outline a specific, sequential software update process (e. G. , older versions need TSB 2067021 first for TSB 2069112). Other owners successfully resolved rebooting with these updates. This malfunction is analogous to other Audi mib3 software instabilities, as evidenced by NHTSA recall number 22v742 (Audi campaign code 91dz). This recall for 2021-2022 Audi models addresses similar digital display/infotainment failures (e. G. , rearview camera loss) via a no-cost software update. This demonstrates Audi's awareness of systemic mib3 software issues impairing safety. I urge NHTSA to investigate this widespread 2020 Audi A4 issue and compel Audi to issue a recall for a no-cost software update (per tsbs) to all affected owners. More detailed documentation, including dealer records and owner videos, is available upon request as there is limited space to detail here.

Vehicles mmi constantly cycling through reboot - inordinate amount of previous complaints about this exact issue - dealer advised a min $1040 ($370 to diagnose + $670 new mmi) to diagnose and change mmi console with no guarantee it will work and that's because: the dealer has not updated mib2 (aka the mmi) using the instructions on a different bulletin, titled "TSB 2067021 - 91 mib3: garage opener/sxm/online radio or other malfunctions b129b11, b129c22, b123b13, b123c13, u044700 or b200000" (latest version is from July 27, 2024, they've had 6 revisions), before applying the most recent update. So it looks like, at a minimum, I'm two updates behind (encompassing of course, a ton of intermediate versions). So right there, the dealerships have been failing by not even taking the time to read Audi's own tsbs. The dealership said: they have seen this before and they have seen many leave without resolve may I please be placed on the list of vins that when all complaints are proven to be true and a recall is issued, I can partake in the mmi update? it truly is dangerous as the entire console shuts down, meaning cameras and system are not available for viewing protection (the minimum safety precautions expected with cameras, etc) Audi needs to recognize this is a widespread issue. It appears that they are picky with who they provide updates to and who they ignore as some owners received an update and while their mmi doesn't function 100%, it doesn't cycle through reboot every 60 seconds.

Mmi system is restarting on a near constant basis, both while parked and driving. Aside from being inconvenient, as you can not use media/navigation/etc while it’s rebooting, it also causes many safety features like drive assist/collision/obstacle detection to malfunction and not work, and is therefore simply outright dangerous.

The mmi unit does a reboot every few mins. Even when driving and when reversing the car which prevents the back up camera to show up.

The mmi system crashes and reboots after about 90 seconds. This affects all parking and collision sensors.

I had experienced this problem prior of the center screen/mimi restarting but typically it used to not be very often maybe once every few weeks. But for the past week it has been happening every 30 seconds to a min. This has caused my backup camera to restart as I am backing up causing me to almost get in an accident. As well as that as I am driving I am constantly having to focus on fixing the mmi and shutting off the volume as whenever it turns back on it plays radio static. I am very disappointed in the way Audi has handled this as I am still below 50,000 miles and they refuse to help. This problem is very frustrating as they don’t even have a 100% fix. Their first option was $598 update which I believe is very unfair considering this only happens to select cars and it’s not like this is an extra feature you’re paying for. The second option they gave was a $5,000 module replacement which is just unbelievable considering this has nothing to do with user fault but rather poor manufacturing. This whole situation is outrageous as I see many other individuals with the same problems and no solutions.

Mmi/infotainment system randomly shuts down every 30 seconds or even less. The entire screen goes black, it even happened when I was backing up the car while looking through the backup camera, which was extremely dangerous. I have tried all kinds of methods to fix but it doesn’t seem to be working, and it getting worse as we speak with more frequent shutdowns.

The Audi mmi keep rebooting for every 1 minute while driving.

Audi mmi (muti media interface) constantly resets while driving the vehicle. The problem began about 4 months ago. The mmi would reboot very infrequently- about once every couple weeks. However, I took the vehicle in for a routine oil change yesterday and when I received the vehicle back, it now constantly resets as soon as it reboots. If I attempt to click a button (like accepting my user profile) the screen immediately goes black. I believe this poses an extreme safety hazard given it can shut off while in reverse when the back up camera is engaged. It is also very distracting constantly seeing the mmi reboot and shut down as every time it reboots it asks for credentials/pins/users etc. Lastly, it's very dangerous because if I'm on a call it tries to constantly kick it over to the bluetooth (but it doesn't work) so I have to manually put the phone back into speaker mode which is extremely distracting.

Audi mmi display constantly shuts off and turns back on with a message about this user not being used despite using it everyday. This happens all the time and has been on going for months. It is dangerous when I’m relying on it for navigation. I have not had this issue looked at at an Audi dealership but have read this issue seems to be widespread with 2020 models. The issue is ongoing and only seems to be getting worse.

The infotainment system will randomly reboot while the vehicle is on and being driven. The system will shut off, initialize, and reload. If using carplay, the system will shut it down and require you to manually reconnect your phone and enable carplay for it to load on the display. This system will reboot randomly about 4-5 times within a 30 minute/30 mile drive. To reconnect your phone you have to click on the display because the vehicle does not have a command knob that can be used without having to reach the display.

I have started experiencing issues with the mmi (infotainment system) system rebooting every few minutes. It was very sporadic at first, but now it is at the point where I frequently don't have time to get into the system before it starts the reboot cycle again. When this happens, the screen will go blank for several seconds. Then a message will show for several seconds saying that the system is loading. The system will then try to guide me through several prompts to try to log back into the car's mmi system. Even if I choose "guest user" I am shown multiple prompts before I get into the system and can use the functions located in the mmi. This can and does happen while driving, while parked, and while backing up. This reboot sequence makes all of the safety features, including collision avoidance and the backup camera inaccessible during this time. Sometimes, the system reboots before I have time to even back out of my driveway. Frequently, I don't have time to sign in or work through the prompts to get to the working system before it starts rebooting again. This issue started in February, 2025, but it was infrequent then. Over the past month, the issue has been persistent with the system rebooting every 5 minutes or less. This is very distracting while trying to drive and takes the driver's attention away from driving. As stated before, it also makes the safety features of the vehicle inaccessible - such as collision avoidance and backup camera.

Mmi keeps turning off, at this point it's every few minutes. Message states "the selected user has not been in the vehicle for an extended period . . . ", something like that. But if you close out the message my info is still available to log into. I've tried a soft reboot by holding down the volume button, I've tried a factory reset and nothing works. It's getting dangerous because now it shuts off sometimes when I'm going in reverse and the camera is then unavailable. It shuts off when I'm utilizing it for directions via android auto. It's annoying and it's ridiculous that I have a luxury vehicle with this kind of issue. It's been going on for over 6 months now and only appears to be getting worse.

There is nothing wrong.

My electronic infotainment system keep rebuilding and is affecting my rear camera when backing up I find it unsafe.

Audi mmi (display console/dashboard cluster) randomly turns off and reboots while driving.

The vehicles mmi system out of nowhere keeps turning off and says "checking for remote access rights" and this happens constantly now for the past few months. Happened to reboot when I was backing out of a parking spot and my rear view camera turned off as well as the parking collision monitoring system. They all stopped working and I almost hit a pedestrian walking behind my car. This is a serious safety concern as this keeps happening every few minutes now in my car. Not sure if it became more persistent since my last vehicle maintenance few months ago but it's a problem. Driving with navigation engaged, it happened again while on highway and system shut down and I had no clue where to go. It's very distracting to happen while driving and all shut down.

The infotainment screen (mmi) responsible for rear camera, cross traffic alert, entertainment and controls some crucial vehicle functions tends to shut off by itself while driving. This issue occurs constantly and it's very sporadic. Nothing triggers this just the car decides to do it on it's own. This causes me to lose visuals of my surrounding, and sensor information and the ability to listen to maps and music. Raises a major safety concern.

The entire mmi shuts down anywhere from every 30 seconds to 5-6 minutes. It has to then completely reboot, gives a pop up that “user has not been in vehicle for an extended amount of time” - I tried trouble shooting with Audi care over the phone, re added myself as a registered user with remote rights - makes me type my pin every time this happens. The safety risks are the distraction it takes from driving, especially when I am using it for navigation in an unfamiliar area, often getting lost and flustered and distracted.

While driving, the infotainment screen (mmi system) randomly reboots without warning. This happens frequently, often multiple times during a single trip. When it restarts, the screen goes black and temporarily disables important functions like the navigation, rear-view camera, Audio, and vehicle settings. This poses a safety risk by distracting the driver and making it difficult to safely reverse or park. I brought the vehicle to the dealership, and they confirmed the only solution is to replace the mmi system. However, I’ve seen many other Audi A4 owners online report the exact same issue. Given how widespread this appears to be, I believe this should be addressed as a manufacturer defect rather than a repair cost placed on the owner. There were no warning lights or messages before the screen began to fail.

The vehicle multimedia interface (mmi) has randomly rebooted itself on every trip for the past three months. This condition has occurred while reversing the vehicle, leaving the rear camera view blank.

Mmi screen reboots multiple times while driving. Seems to happen more often when usb is plugged in for car play. Unable to access or view anything on screen like navigation which is quite unsafe.

Mmi unit reboot itself randomly.

While reversing, the “mmi system” which displays information on the central display screen, such as the backup camera, will crash and reboot. This will also occur while driving normally. If this happens while reversing, the car will then warn me that the backup camera safety feature is inoperable. This issues was not solved by a deal software update and requires a $4000 repair charge to resolve. Backing up without the camera operable at random times does not seem safe.

My Audi A4 mmi continuously reboots randomly, every 5-10 minutes. It started back in January and has now gotten to the point where it wont last a full song on the radio without rebooting. This is an issue for thousands of Audi owners as a simple google search provides all of the same issues. Https://forums. Ross-tech. Com/index. . Read more...

The mmi keeps rebooting, even if I’m listening to the radio and my iphone isn’t plugged in. If my iphone is plugged in, it also does it and shuts off and reboots.

I information screen keeps rebooting every 15 minuets or so loosing navigation and user settings. Often complains it needs to log in a new user while driving and key not working.

Mmi (infotainment system) shuts down periodically while vehicle is being driven or is idling in park. Radio, navigation, etc. , are affected. Also, the vehicles' collision warning system shuts down at the same time. Generally, the system will reboot itself within a few minutes. There is no real pattern to this issue as it may occur several times during a short trip in the car. The next day it may not happen at all. I contacted Audi dealer who stated they are not familiar with this issue and knew of no fixes.

1) about two months ago, my 2020 Audi A4's mmi began crashing and rebooting randomly while driving. Most of the time, I had connected my phone via bluetooth to the mmi, and was playing music from my phone. 2) once it crashes and reboots, most of the time it would pick up my phone's bluetooth signal again, and show the music file that is still playing, but there would be no sound from the car's sound system. 3) even after I park, shut off my car, and restart it, the same problem would persist -- the car recognizes that a music file is playing, but no sound. 4) the frequency and randomness of the incidents picked up as time went along. Sometimes it would not crash for the entire duration of my commute; sometimes it would crash within minutes; sometimes it would crash multiple times. No discernible pattern. 5) later on, I discovered that the mmi would crash even when I did not have a bluetooth connection, nor any cord plugged into the car via usb. 6) between June 19-20, 2025, niello Audi in sacramento ran a software update for me. I picked up the car on the afternoon of Friday, June 20, and did not drive it again until Monday, June 23. 7) there was no incident between the morning of Monday, June 23 through the morning of Thursday, June 26. 8) on the evening of [xxx], the mmi crashed and rebooted within one minute of the car starting up, before I had even exited my work garage. 9) on the evening of [xxx], the mmi crashed and rebooted within 10 minutes of the car starting up, with no bluetooth or hardwire connection to the car at all. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The mmi (the infotainment system on the dash) randomly turns off and resets every few minutes. This is a widespread issue based on a quick google search.
