Audi S5 Sportback

I am filing this safety complaint regarding my 2025 Audi S5, VIN [XXX]. Since taking delivery on [XXX], the vehicle has experienced repeated and intermittent malfunctions involving the driver-assistance and steering systems. On numerous occasions, the Lane Departure Warning/Lane Assist system has applied unexpected and excessive steering input. When attempting to change lanes, including while using the turn signal, the vehicle has at times attempted to steer back toward the original lane. The…

The Lane Keep Assist system will randomly attempt to steer into the shoulder or oncoming lane. This requires rapid correction from the driver to maintain travel within the lane. The most recent incident attempted to steer the vehicle into an oncoming school bus. Multiple repair attempts have been made by three dealers, the third of which performed a camera cleaning and ADAS calibration which was not covered under either the new vehicle warranty or the extended service contract despite…

Since the day of delivery, this 2025 Audi S5 has experienced daily electronic and safety system failures. At least once per day, on startup, the vehicle throws 10 or more warning codes disabling safety-critical systems including blind spot monitoring, lane departure warning, forward collision avoidance, rear traffic alert, and adaptive lighting. These failures occur without warning and persist for varying durations before clearing on their own. Additionally, on 5 occasions the adaptive cruise…

I am writing to file a formal safety defect complaint regarding the EA839 3.0T turbocharged V6 engine installed in various Audi models, including but not limited to the B9/B9.5 S4 and S5, C8 A6 and A7, and 4M/4M.5 Q7 and Q8 (model years approximately 2017 onward). This engine has a well-documented issue with piston skirt wear and failure, which I believe constitutes a significant safety hazard due to the potential for sudden engine failure and loss of vehicle power while driving. As an owner of…
