NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2020 Audi A4. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
The MMI system and all associated functions resets without warning mid drive. The Audi dealership has a bulletin that says a software update is the solution, but has made the problem worse - rather than intermittent resets (once every few days) the system now resets multiple times on short drives (5 times within 20 minutes). This turns off all navigation, radio, phone, CarPlay, Bluetooth, and camera functionality when it happens. Audi has said the only repair is to replace the entire computer module out of pocket - it is a known issue with this car.
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.

The MMI system keeps crashing and rebooting. It can happen as often as every 5-15 minutes. Navigation goes down and parking and backup camera is unavailable until system goes through the reboot process. My understanding is that there are numerous other Audi owners who have this problem, with no clear fix . Audi has nit addressed this or have been able to offer any help or resolution to this issue
The SOS a system has again failed in the car. When this happens, the navigation and the emergency contact button doesn’t work and the cell phone is no longer paired to the car. The module is currently installed in the car. It could be available for inspection if needed. This is a safety issue because the SOS safety button no longer works. Also, the cell phone is no longer useable in the car hands free and this is not safe in emergency. The phone cannot be paired to the car by manually trying to do so. The car no longer recognizes the cell phone. Car will again go in for service on March 3, 2023. My car had this problem before and the SOS module was replaced approx 14 months ago. No one has yet inspected the car. The car is going in for diagnostic service for this very issue at the Audi dealership on Friday March 3, 2023. The message that I received suddenly yesterday while driving was: “No data connection could be established. Please check the network coverage.” Failures to this module result in an unsafe vehicle. Thank you!
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 owns a 2020 Audi A4. 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.
