2020 Audi A4

Starting in around February the MMI (central computer system) system started rebooting at random times while the car was started. At first, I thought there must be something wrong with just my car. I took it into the dealer, and they said there was nothing they could do about it. I did some research and found many other people are having the same issues (thread has over 550 posts linked at the bottom) with the year model and they all started at the same time. I reached out to Audi International, and they say they've never heard of the issue, it's not widespread and to take it to the dealer (which is clearly a lie given the linked thread), when I took it to the dealer, they said Audi international needs to provide and update. Many people on the thread have been told the same thing by Audi and it is extremely frustrating that it's been 5 months, and they continue to deny anything is wrong. I feel this is a major safety issue due to the fact it is extremely distracting while driving and trying to use maps. I took a ~2-hour drive yesterday and the MMI rebooted around 100 times. The other extremely concerning safety issue is if it reboots while parked or in reverse, you lose the backup camera as well as all the proximity sensors until the car is restarted. I know many people have also filed complaints with the NHTSA and Audi International and I'm hoping with enough people speaking up someone will listen and force Audi to provide a solution.

Audi MMI display constantly shuts off and turns back on with a message about this user not being used despite using it everyday. This happens all the time and has been on going for months. It is dangerous when I’m relying on it for navigation. I have not had this issue looked at at an Audi dealership but have read this issue seems to be widespread with 2020 models. The issue is ongoing and only seems to be getting worse.

The entire MMI shuts down anywhere from every 30 seconds to 5-6 minutes. It has to then completely reboot, gives a pop up that “user has not been in vehicle for an extended amount of time” - I tried trouble shooting with Audi care over the phone, re added myself as a registered user with remote rights - makes me type my pin every time this happens. The safety risks are the distraction it takes from driving, especially when I am using it for navigation in an unfamiliar area, often getting lost and flustered and distracted

The 2020 Audi A4 models seem to be experiencing in an outs through the MMI system. They car will reboot multiple times during a drive. I began receiving this around June 23, 2025. They claim it is a software issue however many have not come to a conclusion or fix. This is impairing driving because i am not able to utilize hands free driving which now is a law within many states. Please look into this issue and push the fix amongst all of us drivers on the road.

The infotainment system will randomly reboot while the vehicle is on and being driven. The system will shut off, initialize, and reload. If using CarPlay, the system will shut it down and require you to manually reconnect your phone and enable CarPlay for it to load on the display. This system will reboot randomly about 4-5 times within a 30 minute/30 mile drive. To reconnect your phone you have to click on the display because the vehicle does not have a command knob that can be used without having to reach the display.

The MMI (multi-media interface) frequently reboots during driving, resulting in a black screen and the inoperability of key systems such as the backup camera, rear obstacle detection, navigation, and cell phone tethering (for hands-free operation). These reboots require user input, including entering a PIN to log into the user account (if set up) and repeatedly tapping on the MMI, which can be highly distracting while driving. By its very nature, the reboot catches the driver by surprise and requires diverting attention from driving.Typically, this user input is provided while stationary, immediately after starting the vehicle. This issue constitutes a safety concern, as reboots can occur during reverse parking maneuvers, rendering the backup camera and obstacle detection sensors inoperable until the system reloads. Additionally, reboots completely disable the navigation screens and necessitate multiple user inputs to restore functionality, which can be hazardous while driving. Many states have enacted hands-free laws and requirements that mandate the use of dash-mounted systems to comply with these regulations. The reboots render such systems inoperative. Numerous reports on online user forums suggest that this issue is widespread and affects the same model year vehicles. For instance, see [XXX] . Several Technical Service Bulletins (TSBs) filed with the National Highway Traffic Safety Administration (NHTSA) indicate that available software updates should be applied to address infotainment-related issues. Relevant TSB numbers include: TSB 2067021, TSB 2076404, and TSB 2069112. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The infotainment system reboots at random times. This is a security risk since it often reboots while the backup camera is active. This effectively takes the backup camera offline. This can also distract the driver since the screen blacks out then reboots promoting for two confirmation screens that you normally go through when in park.

The MMI system, which displays navigation and other controls, shuts down and restarts frequently while the car is in motion. The problem occurs at least once every trip, and typically every 10 minutes. In my case, I use Apple CarPlay as my navigation system, and the sudden and unexpected loss of navigation poses serious safety risks to me and others, because I either need to pick up my phone to see the map or make a sudden driving maneuver to correct my course. The incident occurred with two other phones, and even when no phone was connected to the car. And it also happened when another person in my household was driving. So the problem is not phone or driver-dependent. I have not yet brought the car to the Audi dealership for diagnostic service.

1) About two months ago, my 2020 Audi A4's MMI began crashing and rebooting randomly while driving. Most of the time, I had connected my phone via Bluetooth to the MMI, and was playing music from my phone. 2) Once it crashes and reboots, most of the time it would pick up my phone's Bluetooth signal again, and show the music file that is still playing, but there would be no sound from the car's sound system. 3) Even after I park, shut off my car, and restart it, the same problem would persist -- the car recognizes that a music file is playing, but no sound. 4) The frequency and randomness of the incidents picked up as time went along. Sometimes it would not crash for the entire duration of my commute; sometimes it would crash within minutes; sometimes it would crash multiple times. No discernible pattern. 5) Later on, I discovered that the MMI would crash even when I did not have a Bluetooth connection, nor any cord plugged into the car via USB. 6) Between June 19-20, 2025, Niello Audi in Sacramento ran a software update for me. I picked up the car on the afternoon of Friday, June 20, and did not drive it again until Monday, June 23. 7) There was no incident between the morning of Monday, June 23 through the morning of Thursday, June 26. 8) On the evening of [XXX], the MMI crashed and rebooted within one minute of the car starting up, before I had even exited my work garage. 9) On the evening of [XXX], the MMI crashed and rebooted within 10 minutes of the car starting up, with no Bluetooth or hardwire connection to the car at all.
