2020 Audi A4 Complaint Log

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.

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.

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.

Starting in Feb 2025 my MMI will randomly turn off and eventually turn back on randomly. This happens 10 times in 10min. I can’t drive the car due to it being unsafe. It turns maps off, music, calls, and the dashboard. I’ve found 100’s of other Audi 2020 owners having the exact same issue. The complaints and asking for advice are in a site called Audi world. Type in a4 2020 MMI reboot and you’ll see that it started at the same time for all of us. Around Feb. the dealership scanned and nothing came up, they updated and it hasn’t fixed it. They said they don’t know what’s wrong. Called Audi they said the same. Getting the run around. They did offer to look at it for probably $2000 and said they can’t guarantee they’ll be able to fix it. Please make a recall. Started in Feb and is still occurring. Today it restarted 7 times while idle. Doesn’t matter what you do with or without phone. It turns off then eventually back on.

MMI restarting randomly while idling or running and importantly while reversing restart causing the screen blank imposing safety concerns to the driver.

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.

The MMI Radio 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 WHILE DRIVING. The issue started in February 2025. I see numerous other Audi owners that have the same software and operating systems complaining about this. It seems Audi changed something that caused the connectivity to fail. Dealers I called have no clue. Seems that it needs to have a software update. Someone wrote that the were able to get it fixed by updating 3 components from System 32 to system 35.

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.

The MMI component randomly stops working. Over the past four years of driving this Audi the MMI would suddenly reboot itself only once or twice a year. Now for the past three months it tries to reboot itself once or twice a day! It's quite startling for the music to go silent and the screen goes black, the first few times this happened I thought the engine died too (that's scary). It even happens when I'm backing out of my garage, luckily there is never anybody behind me but what if I'm in the mall parking lot. When the MMI reboots itself about half of the time it is similar to a conventional starting procedure, which isn't to bad but just annoying. Other times it wants you to log on as a "guest driver" or "registered driver hasn't been in the vehicle" or it even wants you to punch in a pin number on the key pad which I don't know. All this requires your concentration on the MMI and not on the road. I wish some one could inspect this and confirm my problems before I brought it to the dealer. If I brought my car to the dealer they would charge me for diagnostics and then say they "there is nothing wrong" or worse try to upsell me a whole new unit for mega dollars. I only drive about ten to fifteen miles a day so my time on the road is minimal but it only takes a moment of distraction to have an accident. While there haven't been any warning lamps or messages about the MMI problem there was another symptom to this problem. The control button on the center console and the thumb scroll wheel on the steering wheel had a very distinct delayed reaction. The volume would change 2-3 seconds after I used the knobs and even turn off 2-3 seconds after I hit the button on the console. I think this symptom started to occur before the MMI reboots. One more quirk, after the MMI reboots, the music from my USB drive will start to play not from when the MMI cut out but from when I started the car that morning. It starts to repeat the same songs. Thank You.

The Audi MMI (Multi Media Interface) system will continually shut down and Reset/reboot while driving. It will happen sometimes 3-4 time within a 20 minute drive. The MMI plays a crucial role in enhancing safety features by providing a user-friendly interface for managing various driver assistance systems and safety-related functions. These include features like emergency calls, roadside assistance, and the integration of driver assistance systems like adaptive cruise control and collision avoidance assist.

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.

The MMI randomly turns of or turns on.

Audi mmi keeps turning off even when driving. Wu e I drive it turns off multiple times leaving me with no connection to the car info system.

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

MMI system in 2020 Audi A4 keeps blacking out and constantly rebooting while driving. This issue happens while going in reverse, which crashes the backup camera and triggers a safety warning in the car. It also happens while idling, which also triggers a safety warning in the car about the backup camera being inoperable.

Every 5-20 minutes while the car is on, the infotainment system reboots. This happens with or without a mobile phone plugged in via USB. This affects backup camera and parking sensors because they are not available when the system reboots. There is no warning before the system reboots.

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.

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.

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

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.
