New Car Assessment Program

The 2020AUDIA4 carries 222 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 1 crash, 0 fires, 0 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 4/5 front crash, 5/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2020 A4 is electrical system with 89 filings, followed by unknown or other (58) and back over prevention: warnings (36). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 9 investigation files overlapping the 2020 A4. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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

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

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.

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 loading. The system will then try to guide me through several prompts to try to log back into the car's MMI system. Even if I choose "Guest User" I am shown multiple prompts before I get into the system and can use the functions located in the MMI. This can and does happen while driving, while parked, and while backing up. This reboot sequence makes all of the safety features, including collision avoidance and the backup camera inaccessible during this time. Sometimes, the system reboots before I have time to even back out of my driveway. Frequently, I don't have time to sign in or work throu
