2020 Audi A4

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 3/10.25), 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. 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-b9-platform-discussion-212/mib3-2020-mmi-rebooting-spontaneously-2020-a4-3082501/ ). 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 06788106, opened on 4/23/25, and I'm still pending for a satisfactory resolution. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112.

AUDI MMI (Multimedia Infotainment system) is frequently malfunctioning without any indicators and immediately rebooting. This disrupts and distracts the driver, as it can happen randomly at any point of the drive. As not only does the reboot take several minutes, taking down all NAV/SOUND that was previously on, it requires user input to clear the error window that appears after the reboot. At times, the error windows even requires user input of a PIN mid drive in order to regain full access to the MMI. This issue is reproducable and various forums and other users have identified the common variable of all of us being son VERY old MMI software version and all occuring on MY2020 A4/A5 vehicles. Myself an other driver complaints know our MMI software version is on CL32 (Version 3243 or 3281) yet, the latest software version is already on CL35. This issue has started appear most frequently in Feb/March 2025, which is consistent with other user's complaints. The vehicle has been inspected and there are no issues with battery, engine, or otherwise. I have tried various debug including complete factory reset of MMI and not using any bluetooth connection, but issue still appears. Independent mechanic also belives it is a software issue. There has been various TSBs issued as an overall fix to the MMI (newest being 2076404_3 in 2025) via software update. However, even though these are highly impacted issues to the vehicle and pose as a danger to the driver, AUDI dealership is requiring diagnostics service fee for an intermittent and reproducable issue in addition to a large fee for the work. It is a software update as the fix supposedly, yet they will charge $1k for this to be done, and it is unclear if it will fix the issue as they may claim it is a 1 off user, despite multiple complaints from many drivers. This is not a comfort issue but is a safety issue since it requires active engagement from the driver, it is a dangerous and distracting issue.

MMI (infotainment), and the dashboard screen will turn off randomly and reboot. This is incredibly dangerous as it turns all sound off, and driving visuals like directions, and freezes or reboots, not where you last had it but from a different check point. Audi dealership said there was nothing they could do , after doing 2 software updates.

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.

Emergency Call SOS module function is inoperative. Cannot use the SOS function and hands-free cell phone use through Bluetooth is also inoperative. Went to dealer on 8/31/22 for repair/replacement of module as instructed in Audi Service Action 90T2. I was told the repair is covered by the vehicle warranty. Part is still back-ordered (as of 11/25.2022) and no one can tell me when, or if, it will be available. No ETA as of today. In the meantime I am driving an unsafe vehicle, with no SOS call function, and no hands-free cell phone feature available.

The contact stated that while pulling out of a parking space, there was big rock next to the bumper on the front passenger's side of the vehicle and there was a scallop area with stones next to the passenger's side of the vehicle as well. The contact stated that she lost control of the vehicle and crashed into the scallop area and the vehicle was stuck between the scallop area and the big rock. There was no further information provided. The air bags failed to deploy. The contact did not sustained any injuries and did not seek medical assistance. The contact was able to release the vehicle with the assistance of road side assistance. A police report was not filed. The contact stated that upon starting the vehicle, the check engine warning light, the low oil warning light and other unknown warning lights illuminated. The contact was able to drive the vehicle for approximately 1 mile; however the warning message "Do Not Drive" illuminated. The contact notified the dealer of the failure. The vehicle was towed to the local dealer who diagnosed that the oil pan was fractured and needed to be replaced. The dealer repaired the oil pan and towed the vehicle to the collision shop, where it was repaired. The contact later received notification of NHTSA Campaign Number: 21V295000 (SUSPENSION), which she associated with the failure. The manufacturer was notified of the failure and informed the contact that they would follow up with the dealer. The failure mileage was approximately 12,000.
