What owners report

  • Backup camera defaults to a black graphic screen instead of showing the live camera view, sometimes right after starting the vehicle.
  • The 360-degree top view parking aid reverts to a different graphic mode every time the vehicle restarts instead of keeping the driver's chosen view.
  • The collision avoidance system has erroneously activated at around 25 mph, causing the vehicle to stop abruptly with no obstacle present, including while in reverse.
  • Audi pre-sense has slammed on the brakes during a left turn with oncoming traffic clear, temporarily disabling the vehicle in the lane of oncoming traffic.
  • A steering malfunction warning light came on and the steering wheel became misaligned, recurring even after the steering column was replaced.
  • The transmission has temporarily disengaged at 65 mph highway speed, causing the engine RPM to surge before re-engaging.
