2020 AUDI A4 Complaints

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 - NHTSA 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 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.

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.

Vehicle radio/navigation interface (MMI) will spontaneously shutoff in all modes. Rear view camera and rear cross traffic visual is unavailable. Requires driver input to fix.

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.

MMI screen reboots multiple times while driving. Seems to happen more often when usb is plugged in for car play. Unable to access or view anything on screen like navigation which is quite unsafe

The MMI system will randomly crash and reboot every few minutes preventing access to features like backup camera, rear and side collision warning, navigation, control of driver assistance features, etc. Issue started around Jan/Feb 2025 and is widely reported by Audi owners across the web.

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.

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 had the software update done at Flemington Audi and problem still persists today. 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 https://www.audiworld.com/forums/a4-...20-a4-3082501/. 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.
