So this is my fourth expedition....1 & 2 had new transmissions within a year. 3 was great and now 4 will only start half the time. Drove to the store Sunday and wouldn't start when I went to leave. A few hours later I tried it and it started. I thought maybe it was a fluke?? Nope!! Drove it Monday and it was fine, on Tuesday it would start. Kept trying it and it finally did so I drove it to my local Ford service center and when I got there it wouldn't start again. They have had it and can not figure out what the problem is. It now will start for them. Has this happened to anyone?? Thanks!
