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.

The MMI system, which is the display in the car, keeps rebooting every few minutes. It is extremely distracting while driving. Also during parking or back up the parking assistance and backup camera would suddenly disappear because the system reboots. The rear cross traffic warning stops working during reboot as well.

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.

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.

Starting in Feb 2025 my MMI will randomly turn off and eventually turn back on randomly. This happens 10 times in 10min. I can’t drive the car due to it being unsafe. It turns maps off, music, calls, and the dashboard. I’ve found 100’s of other Audi 2020 owners having the exact same issue. The complaints and asking for advice are in a site called Audi world. Type in a4 2020 MMI reboot and you’ll see that it started at the same time for all of us. Around Feb. the dealership scanned and nothing came up, they updated and it hasn’t fixed it. They said they don’t know what’s wrong. Called Audi they said the same. Getting the run around. They did offer to look at it for probably $2000 and said they can’t guarantee they’ll be able to fix it. Please make a recall. Started in Feb and is still occurring. Today it restarted 7 times while idle. Doesn’t matter what you do with or without phone. It turns off then eventually back on.

Vehicle's MMI started rebooting spontaneously from 4th week of June 2025. It happens randomly during drive and while following GPS directions. I strongly believe this being a software glitch and occurring without codes, it is a safety issue. These reboots are very unpredictable and happens constantly. When reported to Audi Dealers, they don't have a solution for it. After reviewing many blogs, and so many drivers are having this particular issue, I have decided to report it to NHTSA.

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.

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.

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.

NHTSA complaint #11675203 — an unverified report by a vehicle owner.
UNKNOWN OR OTHER
The MMI system in the car spontaneously reboots, every 2-5 minutes. During reboot, the screen goes black and systems such as the backup camera, rear cross traffic detection, rear collision warning, and navigation are lost until the reboot completes and the user has to cycle thru multiple input & loading screens to get back to full functionality. Given the length of time the reboot requires, often the screen gets back to usability, only to reboot again less than a minute later. The reboots are random and occur whether the radio is off, radio playing; bluetooth connected, not connected; android auto running/not running; car moving, car parked; engine off, engine on; cold weather/hot weather; wet weather/dry weather. This should be considered a safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens, and require multiple user input to restore, while driving.

MMI system in 2020 Audi A4 keeps blacking out and constantly rebooting while driving. This issue happens while going in reverse, which crashes the backup camera and triggers a safety warning in the car. It also happens while idling, which also triggers a safety warning in the car about the backup camera being inoperable.

UNKNOWN OR OTHER
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.

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.

The MMI (infotainment) system in my 2020 Audi A4 start to have intermittent reboot issue during normal driving starting earlier this year. It was working expected without reboot until that time. The MMI system reboot creates harzards and danger for drivers because during rebooting, the whole navigation system is not working neither did Carplay. What's even worse is that the back up camera and radar will also be disabled during rebooting. The rebooting time varies from 10s of seconds to minutes, with black screen and/or laggy, frozen screen. After rebooting, the system will have error prompt such as 'The selected user has not been used for a extended period of time' but the selected user has been using the vehicle all the time. Given the issue described above, there are more and more ppl who are experiencing the same issue joined a online thread: [XXX] , in order to identify the issue and helping each other to protect consumer's rights. The issue has been shared to Audi Customer Support thru email and phone calls several times, such as case number: XXXXXXXX, all the help they provided to me is to reset key user of the vehicle but it does not solve the issue.

Starting in around February the MMI (central computer system) system started rebooting at random times while the car was started. At first, I thought there must be something wrong with just my car. I took it into the dealer, and they said there was nothing they could do about it. I did some research and found many other people are having the same issues (thread has over 550 posts linked at the bottom) with the year model and they all started at the same time. I reached out to Audi International, and they say they've never heard of the issue, it's not widespread and to take it to the dealer (which is clearly a lie given the linked thread), when I took it to the dealer, they said Audi international needs to provide and update. Many people on the thread have been told the same thing by Audi and it is extremely frustrating that it's been 5 months, and they continue to deny anything is wrong. I feel this is a major safety issue due to the fact it is extremely distracting while driving and trying to use maps. I took a ~2-hour drive yesterday and the MMI rebooted around 100 times. The other extremely concerning safety issue is if it reboots while parked or in reverse, you lose the backup camera as well as all the proximity sensors until the car is restarted. I know many people have also filed complaints with the NHTSA and Audi International and I'm hoping with enough people speaking up someone will listen and force Audi to provide a solution.

Audi mmi will shut off randomly, while in drive(accelerating or not), reverse, or idle, causing the camera and sensors to become inoperable, and the vehicle gives a warning saying “parking aid: malfunction! Obstacles cannot be detected” only after the mmi system has rebooted. When this occurs while reversing, not only a car but a pedestrian may be passing behind me and I would not know. This issue also causes the car to randomly ask for a pin to log in to the mmi after rebooting randomly (there is no pin that exists for any users in my vehicle and even asks when i am on a guest user), creating further distractions while driving like when i may need to use navigation, especially when the system reboots repeatedly five to six times within a ten minute time frame. This issue has been recurrent from 3/13/2025 to present 7/13/2025

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

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.

The MMI (multi-media interface) frequently reboots during driving, resulting in a black screen and the inoperability of key systems such as the backup camera, rear obstacle detection, navigation, and cell phone tethering (for hands-free operation). These reboots require user input, including entering a PIN to log into the user account (if set up) and repeatedly tapping on the MMI, which can be highly distracting while driving. By its very nature, the reboot catches the driver by surprise and requires diverting attention from driving.Typically, this user input is provided while stationary, immediately after starting the vehicle. This issue constitutes a safety concern, as reboots can occur during reverse parking maneuvers, rendering the backup camera and obstacle detection sensors inoperable until the system reloads. Additionally, reboots completely disable the navigation screens and necessitate multiple user inputs to restore functionality, which can be hazardous while driving. Many states have enacted hands-free laws and requirements that mandate the use of dash-mounted systems to comply with these regulations. The reboots render such systems inoperative. Numerous reports on online user forums suggest that this issue is widespread and affects the same model year vehicles. For instance, see [XXX] . Several Technical Service Bulletins (TSBs) filed with the National Highway Traffic Safety Administration (NHTSA) indicate that available software updates should be applied to address infotainment-related issues. Relevant TSB numbers include: TSB 2067021, TSB 2076404, and TSB 2069112. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
