Typical lane departure system symptoms owners report

  • Owners report the lane keep assist system oversteering, causing the car to sway back and forth within the lane.
  • Some describe the system suddenly pulling the vehicle toward an exit ramp or into an adjacent lane at highway speed instead of holding position.
  • Several owners say the steering wheel jerks the car toward the opposite lane when turning, even after disabling cruise control.
  • A few report the driver assist software becoming corrupted, with dashboard icons flashing on and off and the car behaving as if pushed by a crosswind.
  • One owner linked disabled lane and braking safety systems to a coolant bypass valve fault code that also triggered the check engine light.
