Typical lane departure system symptoms owners report

  • Owners report the windshield-mounted multipurpose camera failing outright, which knocks out Lane Keeping Assist, Road Departure Mitigation, and related systems all at once.
  • Several complaints describe multiple dashboard warnings appearing simultaneously for Collision Mitigation, Adaptive Cruise Control, Lane Keeping Assist, and Auto High Beam after the camera fault triggers.
  • Some owners say the warnings come and go intermittently, with dealers unable to reproduce the fault during inspection.
  • A few complaints mention the failure appearing after the vehicle sat parked for a period or after a battery replacement, with the systems failing again on the next startup.
  • Owners describe losing lane-drift protection and reduced reaction time warnings once the camera-based systems disable themselves.
