    Shortly after my warranty expired last september ([XXX]) my 2020 Audi A4 Allroad started to experience random episodes of the car's main entertainment touch screen rebooting in the middle of the car being operated. This usually would only happen once or twice during maybe an hour long car ride. Then this spring, starting in mid-March the car started to experience the MMI reboots more often, say 6-7 times over an hour long car ride. This started to happen more often, and then…

    The MMI (Information and entertainment system) 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. The issue started in March 2025. It seems there are numerous TSBs (filed with NHTSA) that point to…

    Audi mmi/infotainment reboots repeatedly while driving. It removes my attention from driving and is extremely distracting. Also fails when backing up and back up camera goes black. I have not taken to a dealer as this has been a frequent problem among other 2020 Audi owners.

    Center console screen reboots at random intervals and as many as 10 times in 60 minutes. Complete reboot of the system renders backup camera and other surround view cameras inoperable.

    Vehicle info system (MMI) unexpectedly and repeatedly reboots, affecting rear backup camera and parking assist radar functions at critical moments in addition to navigation and other vehicle functions. In addition to the safety issue with the rear camera and radar failing unexpectedly, the reboot creates distraction for the driver.

    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…

    The MMI (the display with radio, carplay, cameras, warnings etc) restarts without any warning every 5-10 minutes. Does not seem to depend on if apple car play, bluetooth, backup camera etc is used at the time. In 2 cases this has happened while using the backup camera when going in reverse (and many more times when using for media play). This lead to the backup camera not showing and warnings about proximity to objects not working until it has completed the restart of the…

    The MMI (multimedia interface) 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. The process is extremely distracting to the driver and there is no way to prevent it from happening

    The MMI system and all associated functions resets without warning mid drive. The Audi dealership has a bulletin that says a software update is the solution, but has made the problem worse - rather than intermittent resets (once every few days) the system now resets multiple times on short drives (5 times within 20 minutes). This turns off all navigation, radio, phone, CarPlay, Bluetooth, and camera functionality when it happens. Audi has said the only repair is to replace…

    2020 A4 Allroad MMI staring to crash/restart randomly during drive every 5-10min and sometimes back to back crashes for 3-4 times. During this time, no call can be made, no navigation, and no backup camera / backup warning/ backup cross traffic alarm. The issue emerged sometime in February or March 2025.

    The auto uses the Audi MMI system which controls basic functions such as radio, navigation, etc. The MMI in our car has randomly been crashing, which most importantly shuts down navigation at VERY inopportune times! I have read about this in a number of forums, and have tried various ways of resetting the system, but the problem persists. The forums suggest this is a common issue with this generation MMI.

    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…
