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.

AUDI A5 2025 ELECTRICAL SYSTEM

On July 4, 2026 in the early evening, I was driving in the HOV lane of the freeway when the engine abruptly lost power. There was a warning light that came onto the dashboard but I did not see what it said as I was solely concerned about moving safely off to the shoulder in moderate traffic. Once I pulled to the shoulder, I restarted the vehicle and was able to drive home safely. What put my wife and I in great danger was the vehicle losing power without warning when driving on the freeway and having to navigate safely to the shoulder in traffic without having acceleration power. I took the vehicle into the Audi Ontario dealer on July 6 for a rearview camera recall notice and to address the engine problem. I did not drive the vehicle after the July 4 incident but the loss of power did not happen again after I restarted the engine nor when I drove it to the dealer on July 6. The dealer notified me the next day that they could not recreate the engine problem and that the engine automatically turns off after coming to a stop. I explained I had not come to a stop, that I was driving at about 80 MPH with both hands on the steering wheel. I asked about what trouble codes they found and if I could have a print out since this was a safety concern and the vehicle only has 1,500 miles on it. The loss of propulsion was not the auto turn off when coming to a stop. They kept the vehicle for further review and I have not heard back as of July 14. I called to make inquiry and they are supposed to call me back. My concern is not only for me, but also for anyone that has this vehicle year, make, and model - the next person may not be so lucky to navigate to safety if it happens to them.

The contact owns a 2025 Audi A5. The contact stated that while driving approximately 45-50 MPH, the vehicle suddenly decelerated without warning to approximately 20 MPH. The contact activated the hazard lights and safely maneuvered the vehicle onto the shoulder of the roadway. The vehicle remained stopped for approximately five minutes before restarting the vehicle. After restarting the vehicle, the vehicle operated normally, and the contact was able to drive to the residence. The contact notified a dealer of the failure, and the vehicle was towed to the dealer for inspection. The dealer found no faults, software issues, or mechanical failures with the vehicle. The contact was unaware if the vehicle was repaired. The contact stated that a certified letter regarding the failure was sent to the President of Audi; however, no response was received. The failure mileage was approximately 881.

I had adaptive cruise control on in moderately flowing traffic on the highway.  Without warning the adaptive cruise control on it's own turned off/disengaged and slammed on the brakes.  I had not changed lanes nor had anyone moved in front of me.  The weather was clear.  My safety and the safety of those behind me was put at risk.  I've taken the vehicle to the dealer and they have not been able to reproduce the issue yet.  They inspected the vehicle and took it for an initial 7 mile test drive, said they didn't find any problems and tried to return the car.  There were no warning lamps or messages before or after the incident.  I didn't notice any when it happened as I was focused on trying to avoid an accident.  Prior to the incident the adaptive cruise control has turned off multiple times with the message " Adaptive cruise assist: currently not available" for no apparent reason, but this is the first time hard breaking was applied.

AUDI Q5 2025 FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Regarding the adaptive cruise control, sometimes the system won't engage.  The first time this happened a warning popped on the screen saying something about seatbelts.  I've learned that the problem can be "fixed" by pulling off the road and turning the car completely off.  That includes opening a door to silence the radio.  The cruise has always worked afterwards.  Sometimes while driving on cruise control, in a straight line, the car brakes abruptly for no apparent reason.  Granted we were on the interstate and there was traffic but no reason whatsoever to brake.  The cruise control is easily confused on roads with multiple lanes and sharp curves, like on [XXX]  between Asheville, NC and Knoxville, TN.  The car will brake abruptly, seemingly sensing a car in front of me but in a different lane.  Sometimes when reengaging cruise control the speed goes not to the speed I had set but what it "sees" as the posted speed limit.  This caused the car to speed up in a construction zone and slow to a speed below the prevailing speed of traffic around us.
