2020 Audi A4

The Multi Media Interface (MMI) in my 2020 Audi A4 spontaneously reboots while driving. This problem is intermittent but can happen numerous times during a single trip in the car, even trips of less than 10 miles. 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. The issue started in 2024 and the Audi dealership was notified by me on 19 Apr 2024, but they could not replicate the issue and found no "fault codes". There are numerous TSBs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues. The problem continued and I asked the dealer to re-examine it on 27 Mar 2025, but they would not perform diagnostics unless I paid a significant labor charge (since the car is now out of warranty), so I declined. This appears to be a widespread issue based on the numerous reports found on online user forums, affecting the same model year vehicles. (For multiple examples, refer to [XXX] .) Most of the users experiencing this issue have similar software versions, and likely similar production dates. This should be considered an important safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens and require multiple user input to restore while driving. Relevant TSB numbers include TSB 2067021, TSB 2076404, TSB 2069112. Thank you for your attention to this important matter.

2020 Audi A4 went in for service on 2/27. After servicing, car's electrical MMI system started rebooting randomly while driving. When this random reboot occurs, the backup camera, parking collision warning no longer function. On some trips, this occurs as often as 5-6 times while others occur just once. The problem is increasing in frequency. I took it back to the dealer on 4/16 where the only thing they could find via codes was a faulty a/c component. After searching online for a solution, I arrived at several reddit threads with other 2020 audi a4 drivers experiencing similar issues at the end of February. The thread is listed below. [XXX] As mentioned earlier, this lack of system functioning is unsafe as advanced driving features of the car will not work when in a reboot mode. Audi needs to address this issue since this isn't only my car, but appears to have affected the entire 2020 Audi A4 model line.

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.

MMI shuts off while driving every day. My car started doing an annoying thing where while driving the MMI randomly shuts off and reboots. I’ve tried everything I can think of to both replicate it and stop it but nothing has worked. I typically have my iPhone plugged in and Apple CarPlay on with Google maps running. It does it when I have it that way, it does it when I don’t have my phone connected either. I also can’t predict when it’ll do it. When it reboots I sometimes get “The selected user has not been used in this vehicle for an extended period of time. Please enter the myAudi user information again. This requires you to switch to the guest user.” When I switch to guest it does the same thing.

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

Restoring functionality requires user input to get through the loading screens. The issue started in February 2025 and the vehicle has been inspected by the Audi dealership (on 3/10.25), who verified the concern and attempted a factory reset (which did not solve the issue), and they continue to claim there's nothing they can do since their OBD scans return no fault codes, even though there are numerous TSBs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues.

It is also interesting that most of the users experiencing this issue, also report it starting around the same time (Jan/Feb 2025), and they all have similar software versions, and likely production dates. This should be considered a safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens, and require multiple user input to restore, while driving. I have also filed a case with Audi Customer Experience (as many other customers have for this issue) and the number is 06788106, opened on 4/23/25, and I'm still pending for a satisfactory resolution. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112.

AUDI MMI (Multimedia Infotainment system) is frequently malfunctioning without any indicators and immediately rebooting. This disrupts and distracts the driver, as it can happen randomly at any point of the drive. As not only does the reboot take several minutes, taking down all NAV/SOUND that was previously on, it requires user input to clear the error window that appears after the reboot. At times, the error windows even requires user input of a PIN mid drive in order to regain full access to the MMI. This issue is reproducable and various forums and other users have identified the common variable of all of us being son VERY old MMI software version and all occuring on MY2020 A4/A5 vehicles. Myself an other driver complaints know our MMI software version is on CL32 (Version 3243 or 3281) yet, the latest software version is already on CL35. This issue has started appear most frequently in Feb/March 2025, which is consistent with other user's complaints. The vehicle has been inspected and there are no issues with battery, engine, or otherwise. I have tried various debug including complete factory reset of MMI and not using any bluetooth connection, but issue still appears. Independent mechanic also belives it is a software issue. There has been various TSBs issued as an overall fix to the MMI (newest being 2076404_3 in 2025) via software update. However, even though these are highly impacted issues to the vehicle and pose as a danger to the driver, AUDI dealership is requiring diagnostics service fee for an intermittent and reproducable issue in addition to a large fee for the work. It is a software update as the fix supposedly, yet they will charge $1k for this to be done, and it is unclear if it will fix the issue as they may claim it is a 1 off user, despite multiple complaints from many drivers. This is not a comfort issue but is a safety issue since it requires active engagement from the driver, it is a dangerous and distracting issue.

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.
