2020 AUDI A4 Complaints

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 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.

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

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. See this issue occurring at the same time for the same model as Audi has not been helpful in correcting: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 infotainment system occasionally shuts down while driving, resulting in a blank screen and a reboot of the MMI after a short period. This is particularly concerning when backing up the car, as the sensors and backup cameras also become inoperative. The Audi dealership in Seattle performed the annual scheduled service in May 2025 but did not investigate this problem.

Radio keeps cutting off and on randomly, nothing it seeming to fix the problem and all 2020 a4 owners have been running into this. It is also messing with backup camera. This needs to get brought to attention and find a solution.

*The problem with the vehicle is within the Multi-Media Interface system. The MMI will randomly restart while driving, without warning. *This random and frequent reset has lead to issues with following maps (i.e. missing turns, lost in traffic/while on the road) and while backing up (i.e. system turns off while using backup camera and safety sensors to back up). *The issue was reproduced when I had a diagnostic screening completed on 6/9/25 by an Audi Dealership. Through the diagnostic screening, it was found to be a software issue that needed to be updated. This was not covered by any warranty or plan. *The vehicle was inspected by the Audi Dealership in Pittsburgh, PA in November of 2024 and the diagnostic screen was done on 6/9/25. *There were no warnings of issues within the car, the MMI just restarts, randomly with no specific time intervals but happens frequently enough that it has become a safety issue while driving. This issue started to happen in February/March of 2025.

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.
