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 the federal safety agency 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 the federal safety agency 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.
2020 Audi A4 electrical complaints
Page 2 of 4: complaints 11 to 40 of 92, newest first, as owners wrote them.
MMI screen keep turning on and off every minute. This MMI is a brain of audi which controls cameras, sensor for brake and collision, parking assistance, etc. This MMI malfunction has been a big issue and none of the dealer had a permanent solution for the fault. As this MMI function begin to get worse, it could shut off the remaining functions as odometer, speed meter.
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.
The Audi MMI screen has started shutting off and rebooting then giving errors when trying to reboot. Caused a problem while we were using vehicle navigation in NYC and also lost backup guidance when parallel parking. Also dangerous in that it distracts driver with error messages. This started about two months ago once or twice a day but now happens every 2 to 5 minutes.
The MMI (display/menu) continuously reboots every few minutes, which disrupts GPS navigation and back-up camera. This causes distraction and poses a safety risk while driving. This is a common problem among similar Audi software users but has not been addressed by the dealership. No other warnings appear, it will prompt me to re-log in after each reboot.
Audi MMI (computer that controls radio, backup cameras and sensors) is rebooting constantly without warning. When this occurs and the driver is in reverse, the camera shuts down, as do the backup related safety systems, collision warning, rear cross traffic etc.
A permanent failure of the emergency call module control unit and communication unit. The affected vehicles will not be able to establish an online connection. NO GPS, bluetooth and system rebooting constantly.
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 MMI system still reboots every 1-2 minutes while driving. When I am backing up, the camera screen and sensors stop working because the MMI reboots and shuts the screen off.
MMI repeatedly reboots during operation creating visual distraction. MMI system unavailable for monitoring/setting tire pressure and when rebooting makes reverse camera inaccessible. Also eliminates ability for phone to be paired to car for incoming calls or messages and eliminates ability for handsfree text, voice to text, and phone calls.
The MMI system continuously reboots - even while trying to back up using the backup camera making it dangerous. It can reboot 5 times in a 3 mile trip.
The MMI spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload. Restoring functionality requires user input to get through the loading screens. The issue started in February 2025. There are numerous TSBs (filed with the federal safety agency) that point to available software updates that should be applied to address infotainment-related issues. This appears to be a widespread issue based on the numerous reports found on user forums online, affecting the same model year vehicles (for multiple examples, refer to [XXX] ). It is also interesting that most of the users experiencing this issue, also report it starting around the same time (Jan/Feb 2025), and they all have similar software versions, and production dates. 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. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Audi MMI (Multi Media Interface) system randomly reboots while driving, losing navigation (either onboard or via Apple CarPlay). This is dangerous. Dealer says they cannot read an error code, but if you do a simple google search, you can see it's a widespread problem.
Started with saying “checking remote access rights,” and then saying I (the key user) hadn’t been signed in for awhile and I needed to re-login. I was dealing with that but now it’s just randomly shutting off while I’m driving….. in a 30 min drive it does it at least once but as many as 4 times. If I’m using my maps from carplay, on a call or using my backup camera it just completely stops and reboots, which takes a min or two before it comes back up. Multiple times I’ve missed turns due to the map going out. It’s dangerous! Took it to the dealer for oil change and mentioned the issue… dealer acted as if it wasn’t a known issue, and said they could charge me the $300? diagnostic hourly rate to take the dash apart and diagnose (bc of course now it’s out of warranty). I called the Audi MMI tech support and they attempted to help me, had to open a ticket for level 2 escalation support…. I waited 3-4 days and then level 2 said they couldn’t help me and I needed to see the dealer. SO frustrating and have noticed SO many others with similar models and same year having the same issue on reddit. Here’s an example…. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The infotainment system (MMI) in my 2020 Audi A4, currently running software version 3243, frequently reboots on its own while driving. When this happens during reverse, the rearview camera shuts off and the screen goes black, eliminating all rear visibility and creating a significant safety hazard. Additionally, the reboot causes Apple CarPlay to disconnect mid-drive, resulting in loss of navigation, traffic alerts, and voice directions, which increases driver distraction and risk. The issue occurs without warning lights or error messages—the screen simply goes black and restarts in a few seconds to a few minutes. The problem began a few months ago and has become more frequent over time. While I have not yet had the issue inspected by a dealer, it is widely documented by other 2020 A4/A5.. owners and has been resolved in many cases by updating the MMI software to version 3696. Audi has issued related Technical Service Bulletin (TSB 2078437/1), but no recall or service campaign has been announced. I believe this is a manufacturer defect that poses a safety risk and should be investigated. The affected components remain in the vehicle and are available for inspection upon request.
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.
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.
Continuously reboot of MMI system which impacts use and utility of main screen inclusive of backup camera, parking, collision warning, etc..
MMI system shutting down randomly every 2 mins cameras and other safety features doesn’t work
The infotainment/MMI system constantly reboots. This system is linked to the rear view camera, navigation, and hands free phone. When it reboots, those systems fail. This appears to be a widespread issue for the 2020+ Audis.
MMI continously shuts off then back on automatically for the duration of my drives. since it is random, it has occured while on the highway where my collision warning does not intervene because the MMI is off. it puts me and others at risk since without warning it shuts off and takes 20-30sec to come back on but only for a few mins until it happens again. I have called the Audi experience who told me to go to the dealer; others i know with the same system have done so to no resolve. I do not want to spend $ on an update that will not resolve the problem. this started on 7/14/25 and without warning, the MMI screen turns off. my fear is that it coincidentally happens at a time when it may be needed and cause a wreck or worse fatal
I’ve had the Audi MMI computer replacement car twice and electrical replaced once and the Audi MMI screen keeps turning on and off when it turns off the charging to my phone shuts off and the backup camera shuts off.
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 A4 2020 B9 model MMI "info-system" constantly restarts itself during the drive, regardless of it being connected via Apple CarPlay, Bluetooth, or radio. MMI constantly restarts without reason, usually within 1 to 3 minutes. When MMI restarts, the rebooting process takes about another 1 to 3 minutes and prevents access to features such as the back-up camera and prevents safe reversal of the vehicle. Furthermore, the constant rebooting of the MMI interferes with the use of the GPS and audio speaker within the car. Which causes an unnecessary distraction when driving. The problem has been reproduced by self and confirmed by others experiencing the same issue within Audi's support forum. The vehicle has not been inspected by the manufacturer, police, insurance representatives, or others due to an unnecessarily high charge required in order to inspect the vehicle. No warning lamps or messages have been initiated prior to the failure or when the failure of the MMI first occurred.
Audi MMI (screen) keep rebooting. I can't use my backup camera. This issue also block the back collision sensor
while driving, including backing up with the camera, the computer restarts itself. Navigation, warnings, and backup camera all restart for about 30 seconds. it has happened while depending on the backup camera. just goes black then restarts.
Audi MMI system is failing repeatedly while driving, turning off all screens and requesting login info during driving to reestablish the the MMI user screens. This is a known issue in 2020 Audi A4 models in the US. Maps, speed, engine info all disappear while driving repeatedly every 2-3 minutes. Dealer replaced SOS module in the past to remedy related issues, but some months later this is still happening. A technical service bulletin has been issued (TSB 2067021/6 software update) but is not covered by the warranty to my understanding. I believe this is related to the MyAudi system that multiple users per account/vehicle. There is a disconnect with this cloud service and the vehicle itself, an this is driving the error. This issue makes the entire MMI interface unusable while driving, and ultimately unsafe during use.
The MMI or the entire system reboots wile driving, including times when backing up. Making the rearview camera to go blank and led to possible accident. I also rely on Navigation system to drive as there are numerous exits and turns for commute, but the system randomly reboots and turns the whole system off. This is causing major safety issues.
The MMI (Multi Media Interface) system is the component that failed. It began repeatedly rebooting, making critical features like Apple CarPlay, navigation, audio controls, and the rear-view camera inoperable. The failure became progressively worse after two separate repair attempts, including a software update. The 5F module, which governs infotainment, has been identified by the dealership as the part requiring replacement. Yes, the vehicle and failed component are available for inspection upon request. The malfunction disables the rear-view camera, which is a critical safety feature especially when parking or reversing in tight spaces. It also prevents access to navigation and voice-activated phone controls, which can increase distraction if drivers attempt to manually use a mobile device as a workaround while driving. The constant rebooting also creates visual and audible distractions in the cabin. Yes, the problem has been confirmed by an authorized Audi dealership (Audi of Smithtown). After the initial repair failed to resolve the issue, the dealership attempted the repair a second time. Following further analysis, they recommended a $5,200 repair involving replacement of the 5F module, which supports that they confirmed the problem exists and persists. The issue has been inspected and diagnosed by an authorized Audi dealership (Audi of Smithtown), but there is no mention of inspection by Audi of America, police, or insurance representatives at this time. There were no warning lamps or dashboard messages, but the primary symptom was the MMI system randomly rebooting. Initially, the reboots were occasional, but over time became constant to the point where the system was entirely unusable. This issue was present before the June 5, 2025 service visit and worsened significantly after the second repair attempt on June 21, 2025.
MMI system in the radio. It turns off about every 20 mins and restarts on its own. Maps and directions disappear, causing me to enter the information again. It ends phone calls. It is extremely distracting, especially when I lose my location/directions. I have often times missed my turns. This has been going on for approximately 3 months. I will not let my son or daughter drive this vehicle due to the electrical failure.
