2013-2019 vehicles equipped with a LKS 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 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). Further information on the LKS can be found in the owners manual. If the customers concern is due to the LKS functioning as intended, do not attempt to repair.
