Driver Assist & Collision Avoidance complaints by model year
Vehicle performs a complete stop in the middle of a drive on the freeway. I loose sight of where I am going due to this sudden break, without knowing the UNKNOWN OF WHAT WILL HAPPEN. The vehicle has been inspected by Audi dealership over four times for this issue, in which they are not resolving this problem and stating nothing has been discovered by the scanner. The only message followed by the immediate breaking is ,"Emergency Assist: Cancelled". I have been denied a buyback two times because it's not considered a "repair". They are not taking my situation and safety concern seriously and I am hopeless.
NHTSA complaint #11758078 — an unverified report by a vehicle owner.
The MMI infotainment head unit reboots spontaneously and repeatedly while the vehicle is in operation. The screen freezes, goes black, and restarts, reliably within 7-8 minutes of completing the previous boot. This repeats continuously for the duration of any drive. I have verified this is not related to a connected phone. I tested with three different phones on three different operating systems, and with no phone connected and powered off entirely. The reboot cycle occurs identically in all cases, whenever the vehicle is running. The critical safety failure: if the vehicle is placed in reverse near the time of a reboot, the crash disables all Parking Assist functions. The rear backup camera becomes fully inoperable while the vehicle is actively backing up, and the side cameras are sometimes lost as well. The Parking Assist system, including the backup camera, remains offline until the vehicle is shut off and left sitting for 15 to 30 minutes. There is no warning before this occurs. This means the federally mandated rear visibility system can and does fail without warning during the exact maneuver it exists to make safe. I have video documenting the backup camera being disabled while reversing. The vehicle has been to the dealer for these concerns. A software update was performed per Audi TSB on 3/27/2026 (RO 356075) and did not resolve the issue. The vehicle was diagnosed again 7/1/2026 through 7/9/2026 (RO 361320) and the dealer was unable to duplicate the concerns at that time. The reboot behavior has since become continuous and reproducible.

NHTSA complaint #11739743 — an unverified report by a vehicle owner.
13 Jun 25 2100 hrs - Auto went thru multiple of errors and transmission would not go into gear, electric door locks released all emergency pull handles and car was not able to move. Called Audi Emergency Service. Tried to get out of vehicle and door could not be opened from inside the vehicle. I had friend come and get me out of vehicle by me pushing on the inside and her pulling the emergency pull. DANGEROUS! Emergency Service could not come to tow vehicle for three days because of being on an Air Force base and no tow companies that Audi contracted with had a realID or a clean criminal record. 16 June, Audi finally finds company to tow vehicle, at that point vehicle had completely died and could not be jump started. Car towed to Audi Service. Car in service for three weeks and I was told it was just a bad battery. I took vehicle with doubts of repair and for the next four months car would pop multiple software errors specifically on driver assist, no sound, dash going completely blank while driving, etc. The next major electrical failure was on 17 Nov, once again car would not start nor could it be jump started by tow company. Car once again towed to Audi on the same day. Car in service until 23 Dec and Audi said it was related to TSB 2079690/4 and they have stated that the KD2 should resolve electrical issue with driver door module constantly running and killing car. One day later, already popping driver assist errors. This car is dangerous and Audi knows that this KD2 is a band-aid on a software system that is unreliable and still has no permanent fix. I fear being stranded on a highway and either being stuck in my vehicle and can't get out or not being able to get in car if I get out to try and open hood to check vehicle, I might not be able to get back in because of electric locks.

NHTSA complaint #11707324 — an unverified report by a vehicle owner.
The Multi-Media Interface (MMI) randomly reboots and poses a safety hazard. Several times while reversing using my backup camera, the MMI has rebooted which causes the camera to go blank. This poses a risk to back up into an object or a person during this time. Also during this time, the Rear Cross Traffic Warning system is disabled until the system reboots. Also, while using navigation, the MMI has rebooted on me several times. It has occurred during critical times such as exiting freeways at high speeds. When this occurs it is terribly distracting and could cause an accident. The problem has been re-produced by my dealer. They said it needed a software upgrade and performed that. It worked better for a couple days but is now back to rebooting spontaneously. There were no warning lamps or messages indicating the fault will be occurring. It just reboots and the MMI goes totally blank for about 20 seconds while the system reboots. There seems to be no rhyme or reason to when it will reboot. I can drive for 20 minutes and it may happen 4 times and then another time drive for an hour and never have it happen. Lately, it has gotten so bad I drive my son's car if it is available due to the safety concerns.

Hello, I am writing today to inform you about the safety concerns I have over My Audis MMI issues. The MMI is the multi media infotainment which is operates my back up camera, proximity sensors and navigation. The MMI is stuck in a loop and reboots every 60 seconds. I was backing up and the MMI rebooted on me which abruptly stop streaming what was behind me, my neighbor was also backing up and thankfully I spotted them on my rear view mirror and stop in time before we collided.
NHTSA complaint #11677655 — an unverified report by a vehicle owner.
Beginning in mid July 2025, the MMI system (screen in the center of the dashboard) reboots every 1-2 minutes. In addition to the large distraction this causes while driving, the constant rebooting disables the back-up camera, parking sensors, rear-cross traffic alerts, collision avoidance assist, navigation, as well as everything else that is controlled by the Audi MMI system.

The MMI constantly reboots itself. I have had the car to two dealers and despite software updates, the problem continues. As a result of this, while I have been in reverse the cameras will automatically turn off,

MMI constantly shuts off, often in the process of moving into or out of a parking spot. This suddenly and unexpectedly disables the parking collision warning system, the rear cross traffic warning system, and frontal collision warnings. Very frustrating and unsafe. No solution currently exists. No symptoms prior to this happening; it is widely reported at online forums. No users have been able to have this corrected even at the dealer.

My car’s Multi Media Interface (MMI) keeps restarting every 1 to 2 minutes everyday while driving the carThe MMI runs my navigation (not through my phone) and music by connecting to my phone with Bluetooth. It also shows me my backup camera and diagnostics with the car. Safety is affected by distractions, not knowing where to go, irritation. No dealership has inspected or been able to reproduce the issue. No other issues came before the MMI began restarting.

The MMI system keeps rebooting. Once when I was backing up, the screen started resetting compromising the backup camera display and any cross traffic warning that may of been there.
NHTSA complaint #11674649 — an unverified report by a vehicle owner.
My media display will randomly turn off while driving, idling and parking. It will happen with Apple CarPlay connection and without anything connected, ie just listening to radio. It requires the whole system to reboot an attempt to login, which also often fails. This is a safety concern for both driver and pedestrians as it affects parking visibility when the systems reboots while parking. Also, when shifting into reverse I've noticed a sluggish rear camera activation. The camera output on the display fades up much slower.
NHTSA complaint #11674124 — an unverified report by a vehicle owner.
Starting early 2025 with no changes or modifications or warning - the MMI system in my 2020 Audi A5 began spontanously rebooting. It appears to be rebooting regardless use or radio, CarPlay, or nothing - even after the recent factory reset. Reboots appear to occur at random - sometimes once in 40 mins, or every 3-4 mins. After some research, it appears other similar 2020 cars have recently started experiencing the similar symptoms something this year in 2025. Sudden loss of navigation aid, parking and warning collision, etc have almost resulted in crashes. It was inspected at a dealer, who did not note any other open issues. I suspect there must be a change in how Audi forces the car to call back to their service that resulted in software reboots.
