Latest A5 Sedan complaints
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.

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.
