Rearview System Braking Problems of Audi A5

The mmi system keeps rebooting. Once when I was backing up, the screen started resetting compromising the backup camera display and any cross traffic warning that may of been there.

Starting early 2025 with no changes or modifications or warning - the mmi system in my 2020 Audi A5 began spontanously rebooting. It appears to be rebooting regardless use or radio, carplay, or nothing - even after the recent factory reset. Reboots appear to occur at random - sometimes once in 40 mins, or every 3-4 mins. After some research, it appears other similar 2020 cars have recently started experiencing the similar symptoms something this year in 2025. Sudden loss of navigation aid, parking and warning collision, etc have almost resulted in crashes. It was inspected at a dealer, who did not note any other open issues. I suspect there must be a change in how Audi forces the car to call back to their service that resulted in software reboots.

Mmi constantly shuts off, often in the process of moving into or out of a parking spot. This suddenly and unexpectedly disables the parking collision warning system, the rear cross traffic warning system, and frontal collision warnings. Very frustrating and unsafe. No solution currently exists. No symptoms prior to this happening; it is widely reported at online forums. No users have been able to have this corrected even at the dealer.

The mmi constantly reboots itself. I have had the car to two dealers and despite software updates, the problem continues. As a result of this, while I have been in reverse the cameras will automatically turn off,.

The multi-media interface (mmi) randomly reboots and poses a safety hazard. Several times while reversing using my backup camera, the mmi has rebooted which causes the camera to go blank. This poses a risk to back up into an object or a person during this time. Also during this time, the rear cross traffic warning system is disabled until the system reboots. Also, while using navigation, the mmi has rebooted on me several times. It has occurred during critical times such as exiting freeways at high speeds. When this occurs it is terribly distracting and could cause an accident. The problem has been re-produced by my dealer. They said it needed a software upgrade and performed that. It worked better for a couple days but is now back to rebooting spontaneously. There were no warning lamps or messages indicating the fault will be occurring. It just reboots and the mmi goes totally blank for about 20 seconds while the system reboots. There seems to be no rhyme or reason to when it will reboot. I can drive for 20 minutes and it may happen 4 times and then another time drive for an hour and never have it happen. Lately, it has gotten so bad I drive my son's car if it is available due to the safety concerns.
