MMI (Infotainment system) shuts down periodically while vehicle is being driven or is idling in Park. Radio, navigation, etc., are affected. Also, the vehicles' collision warning system shuts down at the same time. Generally, the system will reboot itself within a few minutes. There is no real pattern to this issue as it may occur several times during a short trip in the car. The next day it may not happen at all. I contacted Audi dealer who stated they are not familiar with this issue and knew of no fixes.

The MMI 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 February 2025 and the vehicle has been inspected by the Audi dealership (on 4/17/25), who applied an update at a cost of $185 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 the federal safety agency) that point to available software updates that should be applied to address infotainment-related issues. 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 [XXX]). 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, [XXX] opened on 4/18/25, and I'm still pending for a satisfactory resolution.

The Multimedia Interface (MMI) infotainment system in my 2020 Audi A4 frequently and unexpectedly reboots during driving. Each reboot causes the display to go black, disabling essential safety features including the backup camera, rear obstacle sensors, navigation, and hands-free phone connectivity until the system fully reloads. Restoring operation requires manual interaction, such as entering a PIN and repeatedly using the touchscreen, which distracts the driver and creates unsafe conditions. This malfunction significantly jeopardizes safety, particularly while driving in reverse, as the abrupt loss of the backup camera and obstacle detection sensors occurs without warning, substantially increasing the risk of collision or pedestrian accidents. Additionally, during normal driving, the sudden reboots disable navigation guidance and hands-free phone operation, which are essential for compliance with state laws regarding distraction-free driving. The need for manual input to restore these functionalities causes further driver distraction, compounding the potential for hazardous situations. The issue initially appeared sporadically over a year ago but increased dramatically around February 2025, now occurring as often as every few minutes. Performing a factory reset provided no improvement. Many owners report identical problems on forums like AudiWorld and Reddit, specifically mentioning the early-2025 onset and similar software versions. Several related Technical Service Bulletins, including TSB 2067021, TSB 2076404, and TSB 2069112, suggest software updates to address infotainment malfunctions. My vehicle underwent scheduled maintenance at an authorized Audi dealer in December 2024; no MMI abnormalities were reported then. Due to the sudden and unexpected nature of these system reboots and the disabling of critical safety and compliance functions, this defect should be recognized as a significant safety risk requiring immediate corrective action from Audi.

Restoring functionality requires user input to get through the loading screens. The issue started in mid-February 2025 and the vehicle has been inspected by a mechanic 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 the federal safety agency) that point to available software updates that should be applied to address infotainment-related issues.

MMI (infotainment), and the dashboard screen will turn off randomly and reboot. This is a safety concern as it turns all sound off, and driving visuals like directions/backup camera, and freezes or reboots, not where you last had it but from a different check point. Audi dealership misdiagnosed the issue once, performed a software update, but the issue persists. Seems to be a widespread problem - the federal safety agency ID 11657000, among others.
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 the federal safety agency) 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.

The MMI system in car will shut down and reboot many times while driving. If in the process of backing up or parking, it will disable the parking sensors as well. I have taken into dealership and they claim it is an iphone update issue. I have contacted Apple, they are not aware of any such issue.
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.
