2020 Audi A4 ELECTRICAL SYSTEM,UNKNOWN OR OTHER

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.

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.

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.

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.

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

The MMI (the infotainment system on the dash) randomly turns off and resets every few minutes. This is a widespread issue based on a quick Google search.

The vehicle multimedia interface (MMI) has randomly rebooted itself on every trip for the past three months. This condition has occurred while reversing the vehicle, leaving the rear camera view blank.

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.

While driving the MMI (infotainment system) spontaneously reboots. The screen goes black, all audio shuts off and proceeds to boot up as if the car had been turned off and turned back on again. This happens multiple times per drive, every day. It can even happen while the car is in reverse and the backup camera is in use which is very dangerous. 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 https://www.audiworld.com/forums/a4-...20-a4-3082501/ ) This started happening full time around Jan/Feb 2025

The MMI (multi-media interface) often restarts unexpectedly while driving, causing the display to go black and disabling essential features like the backup camera, rear sensor alerts, navigation, and hands-free phone connectivity. When this occurs, the system demands user interaction—such as re-entering a PIN (if one is configured) and repeatedly pressing the interface—to restore functionality. These interruptions can be particularly distracting, as they occur without warning and pull the driver’s focus away from the road. In most cases, drivers end up addressing the issue while parked, typically right after turning on the vehicle. This issue started in October-November 2024. This problem raises safety concerns, particularly when the system restarts during reverse parking, temporarily disabling both the rearview camera and obstacle detection sensors until the MMI reloads. Furthermore, these unexpected reboots shut down navigation functions and demand several user interactions to bring the system back online—creating a dangerous distraction while driving. With many states enforcing hands-free driving laws that rely on integrated, dash-mounted systems for compliance, the loss of functionality due to these reboots directly undermines a driver’s ability to meet those legal requirements. Numerous reports on online user forums suggest that this issue is widespread and affects the same model year vehicles.

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.

This safety issue concerns the MMI system. In my state of MA we cannot use a cell phone while driving. The car's MMI system does not connect to the MMI and hands free calling cannot be done. The dealership and Audi have indicated there is no fix for this. The MMI does not currently have any functionality inclusive of various car warnings.
