2020 Audi A4

The MMI or infotainment center turns off and reboots/kicks user out while the car is in motion and also while stopped. The MMI going off has cut out while backing up not allowing the rear camera to be used and has also not allowed the front and rear sensors to be used for parking/auto breaking. There seems to be a large portion of similar complaints and unknown fixes for 2020 models either exactly the same or similar. Personally have not had it inspected or attempted to fix outside the recommended soft reset, user account reset, and even unplugging battery to reset as well. No fix has been identified or has proven to not cause the issue from recurring. This has occurred more frequently in past week or so ~15Jun where it rebooted once in an two drive, 16Jun no reboots for 1.5 hour min drive, 17Jun one reboot for 1.5 hour drive, and 19Jun where it rebooted 7 times in 2 hour drive. There is no warning and seems to be random or when on full screen maps through Android Auto.

The MMI Radio 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 WHILE DRIVING. The issue started in February 2025. I see numerous other Audi owners that have the same software and operating systems complaining about this. It seems Audi changed something that caused the connectivity to fail. Dealers I called have no clue. Seems that it needs to have a software update. Someone wrote that the were able to get it fixed by updating 3 components from System 32 to system 35.

The MMI randomly restarts, starting in March of 2025. This includes when you are reversing, and there is no camera mid-reverse, along with a complete screen shut down. There will be a clicking sound, then a restart on the MMI at any point, typically multiple times while driving. Then it will log you out, have multiple pop-ups, and say technical error at times (then reboot again). It is available for inspection, yes. The highest risk and safety hazard is mid-reversing anywhere (grocery parking lots, garages with cement columns, humans walking behind). It is also quite distracting while driving. My specific dealership didn’t fully test drive the car to recreate it and came back inconclusive, but many others are having this issue occurring at the same time with dealerships reproducing it. By Audi, it has been looked at. There were no warning signs, symptoms, or messages prior to this occurring in March of this year.

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 MMI component randomly stops working. Over the past four years of driving this Audi the MMI would suddenly reboot itself only once or twice a year. Now for the past three months it tries to reboot itself once or twice a day! It's quite startling for the music to go silent and the screen goes black, the first few times this happened I thought the engine died too (that's scary). It even happens when I'm backing out of my garage, luckily there is never anybody behind me but what if I'm in the mall parking lot. When the MMI reboots itself about half of the time it is similar to a conventional starting procedure, which isn't to bad but just annoying. Other times it wants you to log on as a "guest driver" or "registered driver hasn't been in the vehicle" or it even wants you to punch in a pin number on the key pad which I don't know. All this requires your concentration on the MMI and not on the road. I wish some one could inspect this and confirm my problems before I brought it to the dealer. If I brought my car to the dealer they would charge me for diagnostics and then say they "there is nothing wrong" or worse try to upsell me a whole new unit for mega dollars. I only drive about ten to fifteen miles a day so my time on the road is minimal but it only takes a moment of distraction to have an accident. While there haven't been any warning lamps or messages about the MMI problem there was another symptom to this problem. The control button on the center console and the thumb scroll wheel on the steering wheel had a very distinct delayed reaction. The volume would change 2-3 seconds after I used the knobs and even turn off 2-3 seconds after I hit the button on the console. I think this symptom started to occur before the MMI reboots. One more quirk, after the MMI reboots, the music from my USB drive will start to play not from when the MMI cut out but from when I started the car that morning. It starts to repeat the same songs. Thank You.

while driving. These reboots typically happen every 5–10 minutes and result in the temporary loss of safety-critical features like the backup camera, navigation system, and rear cross-traffic alert. The screen goes black, and the system restarts itself while the vehicle is in motion, which is both distracting and potentially dangerous. I brought the issue to my local Audi dealer, who attempted two separate software updates. Unfortunately, the problem continues. The service department reports no faults in the system diagnostics and has stated that they currently do not know how to fix the issue. This persistent malfunction affects key safety systems and creates significant concern when driving.

The MMI system which contains the backup camera and warnings, navigation, phone and radio goes blank and reboots. Continually does this at any time. You can be backing up in a parking lot and the screen goes black. Audi has tried to fix several times and continues to happen. Numerous complaints about this on Audiworld and Reddit. Major across the board problem with the vehicle.
