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.
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 while backing. Losing Navigation Capabilities or backup camera feature while backing up or driving has jeopardized me couple of times since i had to fumble and hit brakes as i was almost handicap momentarily. Audi is aware of this issue and have had issued TSB in 2020 which is attached here, but no recall was ever conducted which they should as this now an industry wide problem. Also, i got to know that S they have issued a 2021 MMI recall affecting over 44k Cars but not 2020, which is very surprising. Based on forums and other users it seems the Firmware version 3243 need an overhaul or even MMI module replacement if firmware update doesn't fix the issue. Request the authority to investigate this known issue for 2020 car line with similar intensity as this a widespread safety hazard. MMIs usually incorporate other modules as well so there is risk for ADAS failures or parking aids.
