I had a noise that I thought was inside the cab turned out to be the cowling. that has to be the biggest piece of s*** engineering I have ever seen. It's 2 pieces held together in the middle by 2 sided tape. this thing spans the entire width of the truck and they use double sided tape to hold it together. Have they never heard of expansion and contraction. The dealership replaced the one side of the cowling. My truck is 2 years old, so I have one side of my cowling all shiny and new the other is faded. ford told them they could only replace one side. I said don't you think it will do it again and they said YEP, but there is a TSB on it and thats the fix ford told them to do. How about the screw holes on both ends of the cowling that hold water causing the screws to rust. Dealership said nothing we can do about that. I love my truck and wouldn't trade, just wish ford would call the owners and asked for imput on improvements.
