There are 4 owner-reported driver assist & adas complaints for the 2020 Audi A4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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!
MMI system / touch screen on dash is "Blacking out" during reverse backing. Cannot utilize the backing camera. Very dangerous when backing. Took car to independent dealer, with no certain diagnosis. I depend on my back up camera pretty much all the time. The first time this appeared was about 6 weeks ago when the MMI lost connection. Attempted reboots. And the issue has gotten worst.
MMI shuts down and reboots randomly without warning and multiply times a day. All the backup camera and safety warning features were disabled while MMI is off. Huge safety concerns!
My Audi MMI/Infotainment system restarts frequently while driving (every 10-15 minutes). This can happen at any point including while reversing. When the system restarts it shut off the backup camera, parking sensors and all other functionality on the screen. When the system restarts it disables navigation as well. This is extremely dangerous for the driver as well as a distraction.
