“over the last 2 weeks, the entire MMI system stops working, the screen goes black, and the system reboots. It happened once when i was backing out of a parking spot and the alerts stopped working. a second time when i was pulling into a spot and the screen went black as well. this is a MAJOR safety-related flaw!”

NHTSA complaint #11668746, filed 2025-06

“MMI continously shuts off then back on automatically for the duration of my drives. since it is random, it has occured while on the highway where my collision warning does not intervene because the MMI is off. it puts me and others at risk since without warning it shuts off and takes 20-30sec to come back on but only for a few mins until it happens again. I have called the Audi experience who told me to go to the dealer; others i know with the same system have done so to no resolve. I do not want to spend $ on an update that will not resolve the problem. …”

NHTSA complaint #11673908, filed 2025-07

“The MMI spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload. Restoring functionality requires user input to get through the loading screens. …”

“MMI screen keep turning on and off every minute. This MMI is a brain of audi which controls cameras, sensor for brake and collision, parking assistance, etc. This MMI malfunction has been a big issue and none of the dealer had a permanent solution for the fault. As this MMI function begin to get worse, it could shut off the remaining functions as odometer, speed meter.”

NHTSA complaint #11675978, filed 2025-07

“while driving, including backing up with the camera, the computer restarts itself. Navigation, warnings, and backup camera all restart for about 30 seconds. it has happened while depending on the backup camera. just goes black then restarts.”
