2020 AUDI A4 Complaints

The MMI (multi-media interface) frequently reboots during driving, resulting in a black screen and the inoperability of key systems such as the backup camera, rear obstacle detection, navigation, and cell phone tethering (for hands-free operation). These reboots require user input, including entering a PIN to log into the user account (if set up) and repeatedly tapping on the MMI, which can be highly distracting while driving. By its very nature, the reboot catches the driver by surprise and requires diverting attention from driving.Typically, this user input is provided while stationary, immediately after starting the vehicle. The issue emerged sometime in February or March 2025. The vehicle was last serviced in December 2024. I brought the vehicle to a dealership (Audi of Calabasas, California), who were unable to provide a fix for the problem. This issue constitutes a safety concern, as reboots can occur during reverse parking maneuvers, rendering the backup camera and obstacle detection sensors inoperable until the system reloads. Additionally, reboots completely disable the navigation screens and necessitate multiple user inputs to restore functionality, which can be hazardous while driving. Many states have enacted hands-free laws and requirements that mandate the use of dash-mounted systems to comply with these regulations. The reboots render such systems inoperative. Numerous reports on online user forums suggest that this issue is widespread and affects the same model year vehicles. For instance, see [XXX] . Several Technical Service Bulletins (TSBs) filed with the National Highway Traffic Safety Administration (NHTSA) indicate that available software updates should be applied to address infotainment-related issues. Relevant TSB numbers include: TSB 2067021, TSB 2076404, and TSB 2069112. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

MMI keeps turning off, at this point it's every few minutes. Message states "The selected user has not been in the vehicle for an extended period ... ", something like that. But if you close out the message my info is still available to log into. I've tried a soft reboot by holding down the volume button, I've tried a factory reset and nothing works. It's getting dangerous because now it shuts off sometimes when I'm going in reverse and the camera is then unavailable. It shuts off when I'm utilizing it for directions via Android Auto. It's annoying and it's ridiculous that I have a luxury vehicle with this kind of issue. It's been going on for over 6 months now and only appears to be getting worse.

My Audi A4 MMI continuously reboots randomly, every 5-10 minutes. it started back in January and has now gotten to the point where it wont last a full song on the radio without rebooting. This is an issue for thousands of Audi owners as a simple google search provides all of the same issues. https://forums.ross-tech.com/index.php?threads/48781/ https://www.audiworld.com/forums/a4-b9-platform-discussion-212/mib3-2020-mmi-rebooting-spontaneously-2020-a4-3082501/ https://www.reddit.com/r/Audi/comments/1j5and4/audi_a4_mmi_issues/

The monitor in my vehicle will randomly stop working. This could affect the backup camera or other vehicle systems. It also causes a problem with setting the user, and this controls my settings in the vehicle.

The MMI in the car constantly reboots. Started occasionally doing it once a drive, would restart and then go right back to what I was at. Then it would restart multiple times a trip, not going where I was at. If I had music on it would lower the volume it was rebooted to or go to a different song. The screen would also freeze for a few minutes after in being rebooted. Took it to Audi, they installed an “update” now it reboots every 3-5 minutes, causing serious safety concerns with no access to the MMI stystem.

The MMI constantly reboots every 3-10 minutes every trip. Each time the system reboots, it requires me to interface with it to get it logged back in. The MMI is also the main interface with the navigation system, which restarts as part of the reboot, requiring me to restart the route while driving. Recently, it occurred while driving in downtown Boston, nearing my destination, which required several quick turns, ended up having to back track once the MMI came back on.

The MMI system keeps crashing and rebooting. It can happen as often as every 5-15 minutes. Navigation goes down and parking and backup camera is unavailable until system goes through the reboot process. My understanding is that there are numerous other Audi owners who have this problem, with no clear fix . Audi has nit addressed this or have been able to offer any help or resolution to this issue

The Audi MMI (Multi Media Interface) system will continually shut down and Reset/reboot while driving. It will happen sometimes 3-4 time within a 20 minute drive. The MMI plays a crucial role in enhancing safety features by providing a user-friendly interface for managing various driver assistance systems and safety-related functions. These include features like emergency calls, roadside assistance, and the integration of driver assistance systems like adaptive cruise control and collision avoidance assist.

over the last 2 weeks, the entire MMI system stops working, the screen goes black, and the system reboots. It happened once when i was backing out of a parking spot and the alerts stopped working. a second time when i was pulling into a spot and the screen went black as well. this is a MAJOR safety-related flaw!

I own a 2020 Audi and have been experiencing a persistent and widespread issue with the MMI (Multi Media Interface) system. While driving, the MMI randomly shuts down and reboots multiple times during a single trip. This happens whether or not I have any devices connected via Bluetooth, USB, or Apple CarPlay. The shutdowns are completely unpredictable and can occur at any time, causing the loss of navigation, audio, backup camera, and parking sensors. Sometimes, I receive warnings about user profiles or that the sensors have stopped working. I have tried all recommended troubleshooting steps—hard resets, disconnecting all devices, disabling wireless charging, and even having the dealer perform software updates—but nothing has resolved the issue. I’ve also been quoted significant fees for diagnosis and updates, yet Audi has not provided a permanent solution. This problem started for me in early 2025 and has only gotten worse, with more frequent shutdowns that affect the safety and usability of my vehicle. From what I’ve seen in owner forums, I am not alone—many other 2020 Audi owners are dealing with the exact same problem. I believe this is a software issue affecting a large number of vehicles, and I urge the NHTSA to investigate for a possible recall or manufacturer fix.
