I'm new to the forum and haven't had the time to search, but has anyone else with a 2015-2017 had an issue with the rubber adhesive that secures the cheap plastic frame around the rear facing window/sliding window fail? Whoever it was at Ford that decided a $2 piece of plastic was a good idea to frame and secure the rear sliding window is, well, I can't say it on this forum. That was the last thing I ever thought would be an issue with my truck. I had a leak and couldn't figure out where it was coming from. That is, until one day, as I was driving down the interstate at 75 miles per hour, i cracked my drivers side window to let in a little fresh air and as soon as I did, the suction, I assume, pulled the frame and the sliding window completely out and into the backseat. I'm glad no one was in the back at the time.

 

Common issue. I fixed mine using two layers of gorilla double sided tape PLUS window adhesive. Has held up for over 2 years now.
