Weirdly, shortly after responding to this post, I was driving on the interstate and my Expedition started fighting me when I wasn't exactly staying in the lane.
I couldn't understand it because I always had it turned off. I pulled over and accessed the settings but could only partially turn it off (alert only).
I reread this post that reminded me about the button to control the system. After looking around on the steering wheel and dash ,I finally found it by the Auto (off/on) button. It was partially behind my Off Roam cell phone holder. I always press the Auto Off button after starting the truck and I must've accidentally turned on the Lane Changing system when pressing the Auto button. Now I once again have a truck that allows me to straighten out curves without getting told not to.
Just strange it happened within days of reading this.
BTW sorry for being somewhat morbid on my last post, one of the anniversaries was coming up.
