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. The intermittent loss of these visual aids creates a hazardous situation, especially when maneuvering at low speeds, parking, or when relying on sensor alerts for proximity to other vehicles or obstacles. Even during normal driving, the sudden loss of the display is a distraction and removes vital information that a driver might rely on. This is particularly concerning as it affects features directly related to situational awareness and collision avoidance. The problem is persistent and has been occurring since July 2025. I have attemptedrestarting the car, checking for software updates. The issue remains unresolved and consistently compromises my ability to safely operate the vehicle.
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…

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.
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.
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
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 cyc…
