I suspect it was the transmission. A lot of noise and then it wouldn’t go into gear. Unfortunately, all the dealership service departments in my area are backed up so I couldn’t find anyone to look at it until next week. I must admit, in my extreme frustration sitting on the side of the road, I wavered in loyalty a few times. Ultimately, I just count myself as the unlucky one who got the one bad apple. Still under warranty though and Ford has always been good to me. My Expedition on order will be my sixth Ford, plus four F150s for my husband. I still recommend.
