MMI module keeps resetting. This causes sudden lost of navigation display and sudden lost of backup camera when reset happens while backing up. Release version: MHI3_US_AUG45S_P3243 Software version: 3243
Many times while driving the Audi MMI system which controls all radio/navigation/controls screen will completely shut off and reboot, leaving the screen blank and functionality gone. When researching online many others have reported the same issue, with Audi unable to provide a definitive cause or a fix for the issue. This is a safety issue as it could cause distraction while driving
Audi MMI system randomly goes dark and reboots during driving - this turns off the rear camera and any GPS system being used to navigate along with the sound system, etc.
The entertainment system goes black every 5-10 minutes while driving
My 2020 Audi A4 infotainment MMI keeps rebooting and takes over a minute or so to load back. This has been happening recently and i have rebooted the system and followed the Audi/reddit forums to seek any help but no resolution. It seems most of the 2020 Audis are facing similar issues. This issue is concerning and needs immediate attention since I have had instances where i lost backup camera whi...
The MMI system crashes and reboots after about 90 seconds. This affects all parking and collision sensors.
Multimedia Infotainment system spontaneously reboots causing loss of cameras andcollision avoidance features and requires the driver to re-enter log-in information such as PIN #'s. This is a known software fault that should likely be elevated to recall status.
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 malfunct...
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.
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 s...
I have started experiencing issues with the MMI (infotainment system) system rebooting every few minutes. It was very sporadic at first, but now it is at the point where I frequently don't have time to get into the system before it starts the reboot cycle again. When this happens, the screen will go blank for several seconds. Then a message will show for several seconds saying that the system is...
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 rebo...
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.
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 open...
Vehicle's MMI started rebooting spontaneously from 4th week of June 2025. It happens randomly during drive and while following GPS directions. I strongly believe this being a software glitch and occurring without codes, it is a safety issue. These reboots are very unpredictable and happens constantly. When reported to Audi Dealers, they don't have a solution for it. After reviewing many blogs, and...
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.
I had experienced this problem prior of the center screen/Mimi restarting but typically it used to not be very often maybe once every few weeks. But for the past week it has been happening every 30 seconds to a min. This has caused my backup camera to restart as I am backing up causing me to almost get in an accident. As well as that as I am driving I am constantly having to focus on fixing the MM...
The MMI randomly turns of or turns on.
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.
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.
