2020 AUDI S5 Electrical System Problems

MMI - Multi Media Interface constantly reboots about every 90 seconds. This is a safety issue since if I am backing up and the MMI reboots I lose the backup camera and when the MMI reboots I also lose collision/parking/proximity sensors. This issue started happening with my Audi on 7/26/25 and can be reproduced every time the ignition is on or car is running. From doing a quick search on the internet this is a very common problem that just started happening within the last few months with a number of 2020 model Audi's.

THE RADIO (MMI SYSTEM) IS REBOOTING WHILE DRIVING EVERY 5-10 MIN. DEALERSHIP CAN'T FIX AND IS AFFECTING SAFETY SYTEMS LIKE FRONT AND REAR CAMERAS/SENSORS.

Audi MMI reboots constantly while the car is one. There is about 30 seconds between each reboot. This causes certain safety features like the backup camera to stop working when in use. I am not sure what the cause is but this seems to be a more common issue with the 2020 Audi's.

MMI system is failing, parking assist is malfunctioning, back up camera doesn’t activate, CarPlay turns off mid drive and reboots, navigation not working, car wants to brake at highway speeds as computer system malfunctions, Bluetooth phone connection drops mid call, overall the computer infotainment system has failed.

"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. The reboots have affected other sensors/systems in the car like resetting my stored tire pressure values resulting in a TPMS malfunction warning and blocking use of the SOS call feature resulting in a SOS system malfunction warning. Restoring functionality after the reboots requires user input to get through the loading screens. It’s been happening since I purchased the car less than a week ago. I’m unsure of how long the previous owner dealt with this issue. Factory resets prescribed by the dealer do not resolve this issue. 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. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Main computer, multi media interface, MMI constantly shuts off and disconnects from system. This renders all backup cameras, traffic sensors and impact avoidance sensors inoperative. It also stops speedometer

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. The last few days this issue has gone from happening once or maybe twice a day to almost every single minute I am driving the vehicle. Completely unacceptable and dangerous! Restoring functionality requires user input to get through the loading screens. The issue started in mid 2024 and the vehicle has been inspected by the Audi dealership (06/25), 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 NHTSA) that point to available software updates that should be applied to address infotainment-related issues.

I own a 2020 Audi S5. The central infotainment screen (MMI) has been randomly restarting while driving. At first, it only happened occasionally, but the issue has gotten significantly worse. It now restarts every 5 to 10 minutes during normal driving. When the screen reboots, I temporarily lose access to important vehicle functions, including the backup camera, navigation, and audio controls. This creates a safety concern, especially when reversing or relying on the screen for directions or alerts. Audi has not provided a permanent solution, and I’ve seen others report similar issues online. This seems like a widespread defect affecting visibility and driver safety.

The mmi system reboots randomly throughout nearly every drive. This has happened when backing up causing a loss of access to backup cameras and sensors making me stop in the middle of the road.

The MMI restarts constantly every day sometimes multiple times within minutes of each other. There is no correlation with other vehicle feature or functions that cause these restarts to happen and they are not in any specific pattern . When the MMI system reboots, the rearview camera and parking sensor display go dark, making parking and reversing unsafe, which directly impacts the functionality of the Parking Collision Warning and Rear Cross Traffic Warning systems.

The MMI system will turn off, and reset, while driving. this occurs constantly, starting about two months ago. This causes the screen to go blank, and today I almost ran over a pedestrian as the system stopped while backing up. Luckily, I stopped, but was in cross traffic, and was not an ideal situation. This occurs, and I've tried using as a guest, instead of the user, and the same result occurs with the screen going blank while driving and the MMI system reboots.

Regularly my MMI will restart, screen goes blank, comes back and says I'm not the registered user. Then bluetooth won't work and I get park aid errors and no rear cross traffic or anything. Happens at least 2 times each way to and from work ( 45min ). I usually have to hard reset it twice to get things normal and an ignition cycle to get park aid back.

My 2020 S5 started randomly rebooting the MMI computer that controls all vehicle safety control features. The dealer claimed it was a software glitch caused by an update. They provided a software patch as a solution, but it continues to fail. The dealer says it's on Audi and there's nothing they can do, as the update/fix is corrupt. Audi is not being responsive, and this is an issue impacting many Audi vehicles.

The Emergency Call Module Control Unit has now failed for the second time. If the vehicle were to be involved in a crash, the system will not be able to automatically call for assistance. Vehicle is already subject to Audi service campaign 90T2 to reflash emergency call module control unit, however the unit in my vehicle could not be flashed due to it having intermittent errors. The local Audi dealer is stating the next available appointment to diagnose the issue is in three months. After diagnosis there may be a longer wait to obtain required parts. It is dangerous for a safety critical part like this to be out of action for at least 3 months. Audi should place a higher priority on repairing this issue.
