Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Shortly after my warranty expired last september ([XXX]) my 2020 Audi A4 Allroad started to experience random episodes of the car's main entertainment touch screen rebooting in the middle of the car being operated. This usually would only happen once or twice during maybe an hour long car ride. Then this spring, starting in mid-March the car started to experience the MMI reboots more often, say 6-7 times over an hour long car ride. This started to happen more often, and then it would be around 4-5 times in a 20 minute car ride. I noticed that when this would happen, it would cause issues with the backup camera (the camera would stop function during the 60 second reboot. Also, if a parking sensor (or cross-traffic warning sensor, incorporated with the backup camera) was detecting something near the car during the reboot and the camera turning off, it would throw a safety system communication error on the Audi Virtual Dashboard. It was clearly a safety issue and it made maneuvering to park on a busy street very dangerous for folks outside the car and inside. I went to the dealership twice to get the MMI reboots fixed, and received two software updates and a 5F module replacement (quoted at $5k, Audi offered the part 90% off) - all three attempts resulted in the car with a MMI rebooting even faster. It now reboots and has the same issues as before with the car MMI rebooting between every 2-5 minutes during operation. You can find reports from numerous other 2020 Audi A4 owners with this same rebooting MMI issue here, many of whom have already submitted their own NHTSA safety problem reports in this long thread: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The MMI (Information and entertainment system) 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. The issue started in March 2025. It seems there are numerous TSBs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues. This appears to be a widespread issue based on the numerous reports found on user forums online, affecting the same model year vehicles (for multiple examples, refer to [XXX] ). It is also interesting that most of the users experiencing this issue, also report it starting around the same time (Jan/Feb/Mar 2025), and they all have similar software versions, and likely production dates. This should be considered a safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens, and require multiple user input to restore, while driving. This problem seems to be fixed by implementing TSB 2078437/1, Although I do take issue with Audi charging between 400-600 dollars to implement a safety fix to their faulty software.

The entire Audi command center constantly shuts off every 60 seconds, resetting. Losing access to radio, navigation, parking assistance, all features basically. Seems to be a very common problem on 2020 Audi models if you look on Reddit and there should be a recall.
