Warnings Problems of Audi A4 - part 1

Mmi screen keep turning on and off every minute. This mmi is a brain of Audi which controls cameras, sensor for brake and collision, parking assistance, etc. This mmi malfunction has been a big issue and none of the dealer had a permanent solution for the fault. As this mmi function begin to get worse, it could shut off the remaining functions as odometer, speed meter.

The mmi (display/menu) continuously reboots every few minutes, which disrupts gps navigation and back-up camera. This causes distraction and poses a safety risk while driving. This is a common problem among similar Audi software users but has not been addressed by the dealership. No other warnings appear, it will prompt me to re-log in after each reboot.

Mmi constant rebooting - follow up my 2020 Audi A4 quattro's mmi system constantly reboots (~60 seconds), causing the screen to go black/blank. Component failed: mib3 infotainment software. This persistent issue leads to reboots and loss of digital display. System available for inspection. Safety risk: significant, recurring hazard. Critical safety features are inoperative for ~1 min during reboots, including: rearview camera (backing/parking safety) navigation communication no manual bypass exists; driver loses vital visual information problem confirmation: consistently reproducible. Dealer proposed costly hardware replacement with no guarantee, contradicting manufacturer guidelines for known software issues. Symptoms: continuous black screen, Audi splash, then re-initialization. Problem worsened over weeks. Manufacturer's knowledge: extensive owner research (audiworld, reddit) confirms this as a widespread, documented mib3 software defect for 2020 Audi A4/a5 models. Audi's own technical service bulletins (tsbs) address this: TSB 2069112 (mib3 improvements) TSB 2067021 (mib3 malfunctions) these tsbs outline a specific, sequential software update process (e. G. , older versions need TSB 2067021 first for TSB 2069112). Other owners successfully resolved rebooting with these updates. This malfunction is analogous to other Audi mib3 software instabilities, as evidenced by NHTSA recall number 22v742 (Audi campaign code 91dz). This recall for 2021-2022 Audi models addresses similar digital display/infotainment failures (e. G. , rearview camera loss) via a no-cost software update. This demonstrates Audi's awareness of systemic mib3 software issues impairing safety. I urge NHTSA to investigate this widespread 2020 Audi A4 issue and compel Audi to issue a recall for a no-cost software update (per tsbs) to all affected owners. More detailed documentation, including dealer records and owner videos, is available upon request as there is limited space to detail here.

Vehicles mmi constantly cycling through reboot - inordinate amount of previous complaints about this exact issue - dealer advised a min $1040 ($370 to diagnose + $670 new mmi) to diagnose and change mmi console with no guarantee it will work and that's because: the dealer has not updated mib2 (aka the mmi) using the instructions on a different bulletin, titled "TSB 2067021 - 91 mib3: garage opener/sxm/online radio or other malfunctions b129b11, b129c22, b123b13, b123c13, u044700 or b200000" (latest version is from July 27, 2024, they've had 6 revisions), before applying the most recent update. So it looks like, at a minimum, I'm two updates behind (encompassing of course, a ton of intermediate versions). So right there, the dealerships have been failing by not even taking the time to read Audi's own tsbs. The dealership said: they have seen this before and they have seen many leave without resolve may I please be placed on the list of vins that when all complaints are proven to be true and a recall is issued, I can partake in the mmi update? it truly is dangerous as the entire console shuts down, meaning cameras and system are not available for viewing protection (the minimum safety precautions expected with cameras, etc) Audi needs to recognize this is a widespread issue. It appears that they are picky with who they provide updates to and who they ignore as some owners received an update and while their mmi doesn't function 100%, it doesn't cycle through reboot every 60 seconds.

Audi mmi (screen) keep rebooting. I can't use my backup camera. This issue also block the back collision sensor.

Mmi continously shuts off then back on automatically for the duration of my drives. Since it is random, it has occured while on the highway where my collision warning does not intervene because the mmi is off. It puts me and others at risk since without warning it shuts off and takes 20-30sec to come back on but only for a few mins until it happens again. I have called the Audi experience who told me to go to the dealer; others I know with the same system have done so to no resolve. I do not want to spend $ on an update that will not resolve the problem. This started on 7/14/25 and without warning, the mmi screen turns off. My fear is that it coincidentally happens at a time when it may be needed and cause a wreck or worse fatal.

Continuously reboot of mmi system which impacts use and utility of main screen inclusive of backup camera, parking, collision warning, etc. .

Audi mmi (computer that controls radio, backup cameras and sensors) is rebooting constantly without warning. When this occurs and the driver is in reverse, the camera shuts down, as do the backup related safety systems, collision warning, rear cross traffic etc.

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.

Mmi unit (hdu for Audi/radio/backup camera) keeps resetting. Lose picture when backing up. Definitely a safety hazard.

The vehicles mmi system out of nowhere keeps turning off and says "checking for remote access rights" and this happens constantly now for the past few months. Happened to reboot when I was backing out of a parking spot and my rear view camera turned off as well as the parking collision monitoring system. They all stopped working and I almost hit a pedestrian walking behind my car. This is a serious safety concern as this keeps happening every few minutes now in my car. Not sure if it became more persistent since my last vehicle maintenance few months ago but it's a problem. Driving with navigation engaged, it happened again while on highway and system shut down and I had no clue where to go. It's very distracting to happen while driving and all shut down.

Mmi system / touch screen on dash is "blacking out" during reverse backing. Cannot utilize the backing camera. Very dangerous when backing. Took car to independent dealer, with no certain diagnosis. I depend on my back up camera pretty much all the time. The first time this appeared was about 6 weeks ago when the mmi lost connection. Attempted reboots. And the issue has gotten worst.

The mmi (multi media interface) system is the component that failed. It began repeatedly rebooting, making critical features like apple carplay, navigation, Audio controls, and the rear-view camera inoperable. The failure became progressively worse after two separate repair attempts, including a software update. The 5f module, which governs infotainment, has been identified by the dealership as the part requiring replacement. Yes, the vehicle and failed component are available for inspection upon request. The malfunction disables the rear-view camera, which is a critical safety feature especially when parking or reversing in tight spaces. It also prevents access to navigation and voice-activated phone controls, which can increase distraction if drivers attempt to manually use a mobile device as a workaround while driving. The constant rebooting also creates visual and Audible distractions in the cabin. Yes, the problem has been confirmed by an authorized Audi dealership (Audi of smithtown). After the initial repair failed to resolve the issue, the dealership attempted the repair a second time. Following further analysis, they recommended a $5,200 repair involving replacement of the 5f module, which supports that they confirmed the problem exists and persists. The issue has been inspected and diagnosed by an authorized Audi dealership (Audi of smithtown), but there is no mention of inspection by Audi of America, police, or insurance representatives at this time. There were no warning lamps or dashboard messages, but the primary symptom was the mmi system randomly rebooting. Initially, the reboots were occasional, but over time became constant to the point where the system was entirely unusable. This issue was present before the June 5, 2025 service visit and worsened significantly after the second repair attempt on June 21, 2025.

Mmi (infotainment), and the dashboard screen will turn off randomly and reboot every 2 minutes. 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. It has happened while I have been backing up and backup camera has rebooted during backup. Parking collision has also malfunctioned multiple times - but primary issue is the mmi rebooting even while driving on the freeway.

The Audi mmi screen has started shutting off and rebooting then giving errors when trying to reboot. Caused a problem while we were using vehicle navigation in nyc and also lost backup guidance when parallel parking. Also dangerous in that it distracts driver with error messages. This started about two months ago once or twice a day but now happens every 2 to 5 minutes.

While driving, the infotainment screen (mmi system) randomly reboots without warning. This happens frequently, often multiple times during a single trip. When it restarts, the screen goes black and temporarily disables important functions like the navigation, rear-view camera, Audio, and vehicle settings. This poses a safety risk by distracting the driver and making it difficult to safely reverse or park. I brought the vehicle to the dealership, and they confirmed the only solution is to replace the mmi system. However, I’ve seen many other Audi A4 owners online report the exact same issue. Given how widespread this appears to be, I believe this should be addressed as a manufacturer defect rather than a repair cost placed on the owner. There were no warning lights or messages before the screen began to fail.

The mmi system in car will shut down and reboot many times while driving. If in the process of backing up or parking, it will disable the parking sensors as well. I have taken into dealership and they claim it is an iphone update issue. I have contacted apple, they are not aware of any such issue.

The mmi system which contains the backup camera and warnings, navigation, phone and radio goes blank and reboots. Continually does this at any time. You can be backing up in a parking lot and the screen goes black. Audi has tried to fix several times and continues to happen. Numerous complaints about this on Audiworld and reddit. Major across the board problem with the vehicle.

The mmi system in the car spontaneously reboots, every 2-5 minutes. During reboot, the screen goes black and systems such as the backup camera, rear cross traffic detection, rear collision warning, and navigation are lost until the reboot completes and the user has to cycle thru multiple input & loading screens to get back to full functionality. Given the length of time the reboot requires, often the screen gets back to usability, only to reboot again less than a minute later. The reboots are random and occur whether the radio is off, radio playing; bluetooth connected, not connected; android auto running/not running; car moving, car parked; engine off, engine on; cold weather/hot weather; wet weather/dry weather. 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.

Infotainment systems randomly reboot, which can happen when reversing, and reverse camera goes black during the incident is a safety concern.

The mmi (infotainment) system in my 2020 Audi A4 start to have intermittent reboot issue during normal driving starting earlier this year. It was working expected without reboot until that time. The mmi system reboot creates harzards and danger for drivers because during rebooting, the whole navigation system is not working neither did carplay. What's even worse is that the back up camera and radar will also be disabled during rebooting. The rebooting time varies from 10s of seconds to minutes, with black screen and/or laggy, frozen screen. After rebooting, the system will have error prompt such as 'the selected user has not been used for a extended period of time' but the selected user has been using the vehicle all the time. .

The mmi system, which is the display in the car, keeps rebooting every few minutes. It is extremely distracting while driving. Also during parking or back up the parking assistance and backup camera would suddenly disappear because the system reboots. The rear cross traffic warning stops working during reboot as well.

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).

Mmi (infotainment), and the dashboard screen will turn off randomly and reboot. This is a safety concern as it turns all sound off, and driving visuals like directions/backup camera, and freezes or reboots, not where you last had it but from a different check point. Audi dealership misdiagnosed the issue once, performed a software update, but the issue persists. Seems to be a widespread problem - NHTSA id 11657000, among others.

2020 Audi A4 went in for service on 2/27. After servicing, car's electrical mmi system started rebooting randomly while driving. When this random reboot occurs, the backup camera, parking collision warning no longer function. On some trips, this occurs as often as 5-6 times while others occur just once. The problem is increasing in frequency. I took it back to the dealer on 4/16 where the only thing they could find via codes was a faulty a/c component. After searching online for a solution, I arrived at several reddit threads with other 2020 Audi A4 drivers experiencing similar issues at the end of February. The thread is listed below. [xxx] as mentioned earlier, this lack of system functioning is unsafe as advanced driving features of the car will not work when in a reboot mode. Audi needs to address this issue since this isn't only my car, but appears to have affected the entire 2020 Audi A4 model line.

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. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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 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.

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 [xxx], opened on 5/2/25, and I'm still pending for a satisfactory resolution. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

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 rear-view camera intermittently fails to engage when the vehicle is shifted into reverse. When the camera does display, the image sometimes shows horizontal glitch lines/artifacts. This affects backing visibility and parking safety and creates a risk of collision with pedestrians, objects, vehicles, or property. The concern was reported to Audi service along with other electrical/driver-assistance symptoms, suggesting a possible camera, wiring, module, signal-processing, or broader electrical fault. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the rear camera/reverse display is a backing-safety system and the intermittent failure is unpredictable. The vehicle/component is available for inspection, and photo/video evidence and service communications are available.

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. Information redacted pursuant to the freedom of information act (foia), 5 u.

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.

I am filing a complaint concerning my recent experience with the Audi service department located in san rafael, California. On may 24, 2021 I brought my 2019 Audi A4 in for service due to an error message stating, "front parking aid: malfunction! obstacles cannot be detected". I purchased the car in December 2019 from the dealership in burlingame, California. It was previously used as a loaner car, and to my knowledge the car was in original condition with no prior bodywork done on the vehicle. When my car was inspected by the dealership in san rafael, they discovered the error message was the result of a faulty left center front parking aid where pinched wires were found from a previous bumper repair/ removal. I was told that this work required immediate attention, wasn't covered under warranty, and the total cost of repair was $784. 29. I explained to the service advisor, gene frank, that the car had never been in a collision since I owned it, and gene stated that this is a common problem with Audi cars and if he filed a claim with the company, it would be rejected. Gene argued that my car may have been hit in the front by another car on the street, and when I asked why the front of the car doesn't show damage, he explained it was due to the plastic coating on the outside of the surface. Based on the pictures taken by the service inspector and the reasoning for this damage, I argue that this damage was due to a faulty wire. The car is garage kept, has low mileage, has never been in a collision, and has never had body work performed on it. For all these reasons, I dispute the cause of this wire damage. I want Audi to take responsibility for this repair, recall this type of wiring, and refund me the total amount paid for repair.
