2020 Audi S5 Back-over prevention (rear camera) 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.”

“I am writing to report a critical and recurring safety defect concerning the Multi Media Interface (MMI) system in my Audi S5. The MMI system consistently restarts itself approximately every 90 seconds, regardless of whether the vehicle is stationary (parking) or in motion (driving). This issue presents a significant safety hazard because critical sensor information and vehicle status displays, which are shown on the infotainment screen, become unavailable during each restart cycle. …”

“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.”

“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.”

“Audi completed an over the air update and now the mmi screen reboots randomly, making it very dangerous when reversing using the backup camera and relying on parking sensors. Following navigation and it rebooting and having to utilize my cell phone making it difficult to also pay attention to the road.”
