2020 Audi A4

While driving, the infotainment screen (MMI system) randomly reboots without warning. This happens frequently, often multiple times during a single trip. When it restarts, the screen goes black and temporarily disables important functions like the navigation, rear-view camera, audio, and vehicle settings. This poses a safety risk by distracting the driver and making it difficult to safely reverse or park. I brought the vehicle to the dealership, and they confirmed the only solution is to replace the MMI system. However, I’ve seen many other Audi A4 owners online report the exact same issue. Given how widespread this appears to be, I believe this should be addressed as a manufacturer defect rather than a repair cost placed on the owner. There were no warning lights or messages before the screen began to fail.

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. The issue started in February 2025. 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 2025), and they all have similar software versions, and 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. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The MMI system in the car spontaneously reboots, every 2-5 minutes. During reboot, the screen goes black and systems such as the backup camera, rear cross traffic detection, rear collision warning, and navigation are lost until the reboot completes and the user has to cycle thru multiple input & loading screens to get back to full functionality. Given the length of time the reboot requires, often the screen gets back to usability, only to reboot again less than a minute later. The reboots are random and occur whether the radio is off, radio playing; bluetooth connected, not connected; android auto running/not running; car moving, car parked; engine off, engine on; cold weather/hot weather; wet weather/dry weather. 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.

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 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. this started on 7/14/25 and without warning, the MMI screen turns off. my fear is that it coincidentally happens at a time when it may be needed and cause a wreck or worse fatal

The MMI (Multi Media Interface) system is the component that failed. It began repeatedly rebooting, making critical features like Apple CarPlay, navigation, audio controls, and the rear-view camera inoperable. The failure became progressively worse after two separate repair attempts, including a software update. The 5F module, which governs infotainment, has been identified by the dealership as the part requiring replacement. Yes, the vehicle and failed component are available for inspection upon request. The malfunction disables the rear-view camera, which is a critical safety feature especially when parking or reversing in tight spaces. It also prevents access to navigation and voice-activated phone controls, which can increase distraction if drivers attempt to manually use a mobile device as a workaround while driving. The constant rebooting also creates visual and audible distractions in the cabin. Yes, the problem has been confirmed by an authorized Audi dealership (Audi of Smithtown). After the initial repair failed to resolve the issue, the dealership attempted the repair a second time. Following further analysis, they recommended a $5,200 repair involving replacement of the 5F module, which supports that they confirmed the problem exists and persists. The issue has been inspected and diagnosed by an authorized Audi dealership (Audi of Smithtown), but there is no mention of inspection by Audi of America, police, or insurance representatives at this time. There were no warning lamps or dashboard messages, but the primary symptom was the MMI system randomly rebooting. Initially, the reboots were occasional, but over time became constant to the point where the system was entirely unusable. This issue was present before the June 5, 2025 service visit and worsened significantly after the second repair attempt on June 21, 2025.
