2020 Audi S5 Electrical system Problems

“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.”

“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.”

“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.”

“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. …”

“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.”
