Typical lane departure system symptoms owners report

Owners report the lane centering system pulls or jerks the vehicle abruptly to one side, sometimes crossing into an adjacent lane while passing another vehicle on the highway.
Several drivers describe the system as overly aggressive when paired with adaptive cruise control, with steering correction strong enough to almost cause a collision with vehicles in the next lane.
Some owners note the car wanders or drifts on the highway when lane centering is engaged, requiring constant manual correction to stay centered.
One owner reported the over-correction consistently pulled the vehicle left rather than right, and was told by a dealer this behavior was normal.
A few complaints mention sudden, violent steering movement toward oncoming traffic with no warning light illuminated, and the issue could not be replicated at the dealership.
One later complaint describes the vehicle pulling hard to the left on the highway even after an alignment was performed.
