The MMI will spontaneously stop working in the middle of driving. The screen goes blank and then after a few seconds starts a reboot. This requires me to engage the touch screen manually. This will happen multiple times during a 20-30 minute drive. I first started noticing the problem a few months ago sporadically , but it is now happening consistently every time I drive. It is potentially a safety issue, as it is very distracting, shuts off navigation and obstacle detection systems. I have found that this is a common problem many people who have similar year and models of Audis are experiencing. I have not yet contacted the dealership, but it seems from reports it may be a software problem.

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.

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 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.

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!
