While using the Ford BlueCruise system which is supposed to keep the vehicle centered in the lane along when it is in use on the highways it is programmed for, the system in this vehicle wanders throughout the lane from one side lane marker to the other lane marker. When first setting the cruise control which activates the lane assist program in this vehicle, it wants to initially justify to the left (drivers side) lane marker and fights any input from the driver to re-center the vehicle in the lane. If I let the system take the full control, after this initial left line hugging the vehicle will drift over towards the right side lane marker then go back towards the left lane marker and this continues until I deactivate the cruise control entirely when on a BlueCruise enabled highway. Additionally when this is in use, the lane changes the system performs is very abrupt as though the steering wheel was being grabbed and jerked fast to move to the adjacent lane. If this were to occur when there is a slippery spot in the road, I could see this cause a spinout. It is currently at the time of this writing at the Lincoln dealership for this and several other minor issues along with the recall noted as still open on this vehicle — as they cannot get the vehicle to accept the programming for the recall. I have also seen others on the Lincoln Nautilus forums complain about their vehicle doing the same lane wandering like the vehicle is drunk, one person stated in their reply that the almost impacted a vehicle in the other lane. As of the update from the service advisor yesterday (4/3/25) they still have no resolution for the recall issue and have not indicated anything about this issue despite them having put on 44 miles as of this writing on test drives.
