2020 AUDI A4 Complaints

I information screen keeps rebooting every 15 minuets or so loosing navigation and user settings. Often complains it needs to log in a new user while driving and key not working.

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

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) 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. The issue emerged sometime in February or March 2025. The vehicle was last serviced on February 7, 2025, at an Audi dealer. The dealer performed the recommended 50,000-mile service and did not identify any abnormalities related to the MMI during the multi-point vehicle inspection. 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 https://www.audiworld.com/forums/a4-b9-platform-discussion-212/mib3-2020-mmi-rebooting-spontaneously-2020-a4-3082501/. 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.

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.

The MMI / Map Display will intermittently restart itself, sometimes as often as 5 minutes apart. Each time it reboots, there is a chance that manual intervention (PIN code entry or login) is required to get it working again. Until the PIN or password has been entered, maps and other core car features are unavailable. Having to deal with these reboots while driving is severely distracting - losing directions while driving is disorienting and has sent me down wrong turns in the past. If the MMI asks for a PIN or password after reboot, one has to stop looking at the road for however long it takes to enter that. The problem hasn't been confirmed by a dealer or service center, but there are several posts online where ~a hundred people are running into the same software issue, on the same car, that started at around the same time. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives, or others. The dealership wanted to charge me a diagnostic fee to begin taking a look at it, and others haven't had luck getting the problem fixed for that fee. Other symptoms of the problem include a sluggish volume knob response, and CarPlay navigation being sluggish and the car's displayed position jumping back and forth. This problem happens at all speeds, on all types of roads, even at rest. The fact that it started happening on many different cars of the same model year at around the same time implies that it's likely a software issue.

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.

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.

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.

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!
