What 2020 Audi S5 owners say
Electrical system
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.
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.
Driver assistance
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. During the 5-10 second period of the system restarting, the screen goes blank, and all related functions and visual aids, including parking sensor readouts, camera views (if active), and other driver assistance information, are completely inaccessible. …
Sudden reboot of the vehicle's infotainment system, which then repeats every 60-90 seconds consistently. The reboot has happened while reversing the vehicle, which results in losing view of the backup camera and parking sensors / rear cross traffic detection. This issue was originally sparse, but after 7/14 manifests 100% of the time when using the vehicle. This represents a safety issue due to the loss of rear backup camera for 30+ seconds while the infotainment reboots. No warning lights appear, no inspections have been performed by the dealer or any others.
