2020 AUDI A4 Complaints

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 the entire computer module out of pocket - it is a known issue with this car.

The MMI system which contains the backup camera and warnings, navigation, phone and radio goes blank and reboots. Continually does this at any time. You can be backing up in a parking lot and the screen goes black. Audi has tried to fix several times and continues to happen. Numerous complaints about this on Audiworld and Reddit. Major across the board problem with the vehicle.

The MMI (infotainment screen) constantly reboots every 10 minutes or so while driving, requiring me to re log back in in order to use maps or music or calls or backup cameras.

The MMI screen ( infotainment system on dash) frequently turns off while driving. The system requires several minutes to reboot each time. During the reboot process, the backup camera and safety sensors do not work. Additionally, many other features do not work during the reboot Apple Car Play, Phone, Navigation, Radio and Garage Door Opener. The issue started in February 2025 and has persisted during each use of the car thereafter. The reboot will typically occur every few minutes while the car is on.

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.

While backing up in reverse, the MMI screen/system will crash and reboot, and the backup camera will stop functioning. This will trigger an instrument panel safety alert and tone from the vehicle that the backup camera is not functioning (the MMI/entertainment screen will be blank). The system will then reboot. This issue also occurs while driving. The effect is random, and can happen multiple times during a short drive, or just once. Each time the system crashes, the screen goes blank, and then the system will reboot and restart a few moments later. This issue surfaced in March 2025. A local Audi dealer could not replicate the issue, but seemed to understand or be familiar with what I described. After a software update of the MMI system, the issue was not resolved. They have recommended a $4,000 part replacement that they cannot confirm will address or resolve the issue. This is unsafe. This can occur while driving in reverse. This issue affects what I believe to be a government mandated safety feature — the backup camera). So far, I have not found any information that suggests Audi is taking this issue seriously.

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.

While reversing, the “MMI system” which displays information on the central display screen, such as the backup camera, will crash and reboot. This will also occur while driving normally. If this happens while reversing, the car will then warn me that the backup camera safety feature is inoperable. This issues was NOT solved by a deal software update and requires a $4000 repair charge to resolve. Backing up without the camera operable at random times does not seem safe.

The Audi MMI is rebooting with no warning and no apparent reason, often multiple times in as short of a span as an hour. This is causing loss of functionality for handsfree calling and, in some cases, the backup camera, both of which are certainly dangerous. These symptoms first appeared in March 2025. This problem has been verified by an Audi Service Center. The cause was not identified by the technicians.

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 on April 17, 2025, at an Audi dealer. The dealer performed the recommended service. 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.
