2017-2019 Lincoln Continental, 201302019 MKT/MKZ and 2016-2019 MKX vehicles equipped with a LKS (Lane Keeping Assist) system with customer complaints of steering wheel vibration, steering pull or vehicle drift may be due to an alert and/or steering aid input from the LKS.
The LKS system detects unintentional drifting toward the outside of the lane and alerts and/or aids the vehicle to stay in the lane.
Be sure the customer understands how the lane departure warning feature settings work for alert (steering wheel vibration) and aid (steering input toward lane center). This information can be found in the owner’s manual.
