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.

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.

Audi A5 Quattro Purchased new 06/2025. Dealer = Audi Lakeland 1215 Griffen Road Lakeland, FL 33805 Phone: (863) 284-0880 Contact = Service Manager Gary Downey Tire = Bridgestone Turanza LS100 235/45R18 98H REO (Extra Load) Run Flat Tire Tire also includes “Enliten” - don’t know if that is part of model name Brought vehicle in to Dealer for first oil change at 9,006 miles on odometer. Dealer inspected tires and reported both front tires were Red/32” and 2 rear tires were yellow at 5/32”. At 9,000 miles, this is obviously grossly premature tread/tire wear. For front tires to be unsafe to drive at fewer than 9,000 miles is unexpected and others need to be made aware of the risk of premature tread/tire wear to avoid dangerous blowouts that could result in accidents and injury. Feel lucky to have brought vehicle in 1,000 miles early for oil change and for Dealer to have detected. Dealer replaced all 4 tires at no cost and tires are being shipped to Bridgestone. I have Dealer service technician video showing tire/tread wear but was unable to download here — perhaps due to length. Happy to forward if you want it.
