Example complaints

“MMI/infotainment system randomly shuts down every 30 seconds or even less. The entire screen goes black, it even happened when i was backing up the car while looking through the backup camera, which was extremely dangerous. I have tried all kinds of methods to fix but it doesn’t seem to be working, and it getting worse as we speak with more frequent shutdowns”
NHTSA complaint #11673821, filed 2025-07“This safety issue concerns the MMI system. In my state of MA we cannot use a cell phone while driving. The car's MMI system does not connect to the MMI and hands free calling cannot be done. The dealership and Audi have indicated there is no fix for this. The MMI does not currently have any functionality inclusive of various car warnings.”
NHTSA complaint #11501850, filed 2023-01“Audi MMI display constantly shuts off and turns back on with a message about this user not being used despite using it everyday. This happens all the time and has been on going for months. It is dangerous when I’m relying on it for navigation. I have not had this issue looked at at an Audi dealership but have read this issue seems to be widespread with 2020 models. The issue is ongoing and only seems to be getting worse.”
NHTSA complaint #11671365, filed 2025-07“The infotainment screen (MMI) responsible for Rear camera, Cross traffic alert, Entertainment and controls some crucial vehicle functions tends to shut off by itself while driving. This issue occurs constantly and It's very sporadic. Nothing triggers this just the car decides to do it on it's own. This causes me to lose visuals of my surrounding, and sensor information and the ability to listen to Maps and music. Raises a major safety concern.”
NHTSA complaint #11666231, filed 2025-06“The MMI component randomly stops working. Over the past four years of driving this Audi the MMI would suddenly reboot itself only once or twice a year. Now for the past three months it tries to reboot itself once or twice a day! It's quite startling for the music to go silent and the screen goes black, the first few times this happened I thought the engine died too (that's scary). It even happens when I'm backing out of my garage, luckily there is never anybody behind me but what if I'm in the mall parking lot. …”
