Assist Problems of Audi S5

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 being within the terms of both. The first dealer declined to test the vehicle, stating they did not have the necessary equipment to attempt a repair. The second declined to reproduce any of the issues noted at drop-off or perform any inspections beyond a "test drive" to and from the service center from the dealership. At the first two dealers, the lane keep assist was turned off when the vehicle was returned. After the final repair, the vehicle now usually stays in the middle of the lane and the top-down 360 degree camera view now accurately shows obstructions around the vehicle, and no more hidden obstacles suddenly "pop" into the rearview camera. This fault with the lane keep assist is most noticeable when using the system on two lane rural highways, though it can happen elsewhere. The indicator for the side of the vehicle being corrected changes from green to red as expected for intervention during each event. No specific fault codes are logged for this activation. This issue has been present since delivery of the vehicle. Similar loaners from the dealer provided during service do not exhibit this same fault on the same roads in the same locations.

The system warning keeps coming on, I’ve tried to schedule appointments with Audi since 2022 and they have zero appointments available.
