+1 on this.Different take here! If it is happening in the same place in the same road conditions I would bet it is a steel bridge joint or other road imperfection. An abrupt and sudden shift like you are describing sounds like a momentary lose of traction. The joint is much slicker than the other road surface and if it is sunken or raised it could definitely upset your truck. Could also be a low spot with ponded water causing momentary hydro planing. The jerk could be a quick lose of traction then the tires hook back up and you carry on.
Is the movement towards the outside of the turn? Does the steering wheel jerk? Do you hear the brakes pulsating?
I can't comment on the lane assist stuff because I have never used it. I agree with @Doc, don't let a computer drive your truck for you. Especially the steering. Just my two cents.
Had this happen with my 2011 Ranger, 4.0 5 speed with LDS on a ramp on my drive home from work every day. Don’t remember what tires I had but they had questionable traction on wet asfault. Making the left turn onto the ramp and accelerating there was slight imperfection from an intersection repaving that would cause the rear end to momentarily lose traction and jump out. Had to remember to wait a little before accelerating up the ramp to get past that point.
