What owners say
Audi MMI system randomly goes dark and reboots during driving - this turns off the rear camera and any GPS system being used to navigate along with the sound system, etc.
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. Below is link to some on-going issues Audi 2020 users are facing [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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 (infotainment), and the dashboard screen will turn off randomly and reboot every 2 minutes. This is incredibly dangerous as it turns all sound off, and driving visuals like directions, and freezes or reboots, not where you last had it but from a different check point. It has happened while I have been backing up and backup camera has rebooted during backup. Parking Collision has also malfunctioned multiple times - but primary issue is the MMI rebooting even while driving on the freeway.
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.
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.
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.
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.
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.
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 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.
