ELECTRICAL SYSTEM
While backing up in reverse, the MMI screen/system will crash and reboot, and the backup camera will stop functioning. This will trigger an instrument panel safety alert and tone from the vehicle that the backup camera is not functioning (the MMI/entertainment screen will be blank). The system will then reboot. This issue also occurs while driving. The effect is random, and can happen multiple times during a short drive, or just once. Each time the system crashes, the screen goes blank, and then the system will reboot and restart a few moments later. This issue surfaced in March 2025. A local Audi dealer could not replicate the issue, but seemed to understand or be familiar with what I described. After a software update of the MMI system, the issue was not resolved. They have recommended a $4,000 part replacement that they cannot confirm will address or resolve the issue. This is unsafe. This can occur while driving in reverse. This issue affects what I believe to be a government mandated safety feature — the backup camera). So far, I have not found any information that suggests Audi is taking this issue seriously.

UNKNOWN OR OTHER
While reversing, the “MMI system” which displays information on the central display screen, such as the backup camera, will crash and reboot. This will also occur while driving normally. If this happens while reversing, the car will then warn me that the backup camera safety feature is inoperable. This issues was NOT solved by a deal software update and requires a $4000 repair charge to resolve. Backing up without the camera operable at random times does not seem safe.

UNKNOWN OR OTHER
The Audi MMI is rebooting with no warning and no apparent reason, often multiple times in as short of a span as an hour. This is causing loss of functionality for handsfree calling and, in some cases, the backup camera, both of which are certainly dangerous. These symptoms first appeared in March 2025. This problem has been verified by an Audi Service Center. The cause was not identified by the technicians.

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
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 and the vehicle has been inspected by the Audi dealership (on 4/17/25), who applied an update at a cost of $185 which did not solve the issue), and they continue to claim there's nothing they can do since their OBD scans return no fault codes, even though 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 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. I have also filed a case with Audi Customer Experience (as many other customers have for this issue) and the number is, [XXX] opened on 4/18/25, and I'm still pending for a satisfactory resolution. 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)

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
MMI (Infotainment system) shuts down periodically while vehicle is being driven or is idling in Park. Radio, navigation, etc., are affected. Also, the vehicles' collision warning system shuts down at the same time. Generally, the system will reboot itself within a few minutes. There is no real pattern to this issue as it may occur several times during a short trip in the car. The next day it may not happen at all. I contacted Audi dealer who stated they are not familiar with this issue and knew of no fixes.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
The Multimedia Interface (MMI) infotainment system in my 2020 Audi A4 frequently and unexpectedly reboots during driving. Each reboot causes the display to go black, disabling essential safety features including the backup camera, rear obstacle sensors, navigation, and hands-free phone connectivity until the system fully reloads. Restoring operation requires manual interaction, such as entering a PIN and repeatedly using the touchscreen, which distracts the driver and creates unsafe conditions. This malfunction significantly jeopardizes safety, particularly while driving in reverse, as the abrupt loss of the backup camera and obstacle detection sensors occurs without warning, substantially increasing the risk of collision or pedestrian accidents. Additionally, during normal driving, the sudden reboots disable navigation guidance and hands-free phone operation, which are essential for compliance with state laws regarding distraction-free driving. The need for manual input to restore these functionalities causes further driver distraction, compounding the potential for hazardous situations. The issue initially appeared sporadically over a year ago but increased dramatically around February 2025, now occurring as often as every few minutes. Performing a factory reset provided no improvement. Many owners report identical problems on forums like AudiWorld and Reddit, specifically mentioning the early-2025 onset and similar software versions. Several related Technical Service Bulletins, including TSB 2067021, TSB 2076404, and TSB 2069112, suggest software updates to address infotainment malfunctions. My vehicle underwent scheduled maintenance at an authorized Audi dealer in December 2024; no MMI abnormalities were reported then. Due to the sudden and unexpected nature of these system reboots and the disabling of critical safety and compliance functions, this defect should be recognized as a significant safety risk requiring immediate corrective action from Audi.

ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS
MMI (infotainment), and the dashboard screen will turn off randomly and reboot. This is a safety concern as it turns all sound off, and driving visuals like directions/backup camera, and freezes or reboots, not where you last had it but from a different check point. Audi dealership misdiagnosed the issue once, performed a software update, but the issue persists. Seems to be a widespread problem - NHTSA ID 11657000, among others.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, BACK OVER PREVENTION: WARNINGS
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 mid-February 2025 and the vehicle has been inspected by a mechanic who verified the concern and attempted a factory reset (which did not solve the issue), and they continue to claim there's nothing they can do since their OBD scans return no fault codes, even though there are numerous TSBs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues.

BACK OVER PREVENTION: WARNINGS, ELECTRICAL SYSTEM, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
The Multi Media Interface (MMI) in my 2020 Audi A4 spontaneously reboots while driving. This problem is intermittent but can happen numerous times during a single trip in the car, even trips of less than 10 miles. 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 2024 and the Audi dealership was notified by me on 19 Apr 2024, but they could not replicate the issue and found no "fault codes". There are numerous TSBs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues. The problem continued and I asked the dealer to re-examine it on 27 Mar 2025, but they would not perform diagnostics unless I paid a significant labor charge (since the car is now out of warranty), so I declined. This appears to be a widespread issue based on the numerous reports found on online user forums, affecting the same model year vehicles. (For multiple examples, refer to [XXX] .) Most of the users experiencing this issue have similar software versions, and likely similar production dates. This should be considered an important 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. Thank you for your attention to this important matter.

ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS, UNKNOWN OR OTHER
2020 Audi A4 went in for service on 2/27. After servicing, car's electrical MMI system started rebooting randomly while driving. When this random reboot occurs, the backup camera, parking collision warning no longer function. On some trips, this occurs as often as 5-6 times while others occur just once. The problem is increasing in frequency. I took it back to the dealer on 4/16 where the only thing they could find via codes was a faulty a/c component. After searching online for a solution, I arrived at several reddit threads with other 2020 audi a4 drivers experiencing similar issues at the end of February. The thread is listed below. [XXX] As mentioned earlier, this lack of system functioning is unsafe as advanced driving features of the car will not work when in a reboot mode. Audi needs to address this issue since this isn't only my car, but appears to have affected the entire 2020 Audi A4 model line.

ELECTRICAL SYSTEM
MMI shuts off while driving every day. My car started doing an annoying thing where while driving the MMI randomly shuts off and reboots. I’ve tried everything I can think of to both replicate it and stop it but nothing has worked. I typically have my iPhone plugged in and Apple CarPlay on with Google maps running. It does it when I have it that way, it does it when I don’t have my phone connected either. I also can’t predict when it’ll do it. When it reboots I sometimes get “The selected user has not been used in this vehicle for an extended period of time. Please enter the myAudi user information again. This requires you to switch to the guest user.” When I switch to guest it does the same thing.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The MMI (multi-media interface) often restarts unexpectedly while driving, causing the display to go black and disabling essential features like the backup camera, rear sensor alerts, navigation, and hands-free phone connectivity. When this occurs, the system demands user interaction—such as re-entering a PIN (if one is configured) and repeatedly pressing the interface—to restore functionality. These interruptions can be particularly distracting, as they occur without warning and pull the driver’s focus away from the road. In most cases, drivers end up addressing the issue while parked, typically right after turning on the vehicle. This issue started in October-November 2024. This problem raises safety concerns, particularly when the system restarts during reverse parking, temporarily disabling both the rearview camera and obstacle detection sensors until the MMI reloads. Furthermore, these unexpected reboots shut down navigation functions and demand several user interactions to bring the system back online—creating a dangerous distraction while driving. With many states enforcing hands-free driving laws that rely on integrated, dash-mounted systems for compliance, the loss of functionality due to these reboots directly undermines a driver’s ability to meet those legal requirements. Numerous reports on online user forums suggest that this issue is widespread and affects the same model year vehicles.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
While driving the MMI (infotainment system) spontaneously reboots. The screen goes black, all audio shuts off and proceeds to boot up as if the car had been turned off and turned back on again. This happens multiple times per drive, every day. It can even happen while the car is in reverse and the backup camera is in use which is very dangerous. 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 https://www.audiworld.com/forums/a4-...20-a4-3082501/ ) This started happening full time around Jan/Feb 2025
