I'm sure my terminology is bad, but I apologize for not speaking the language. I do not know a lot about trucks, obviously. Regardless, I do know that this is not normal. My truck is a month old, and beside the weather stripping coming off like everyone else this is also happening on the drivers side. This can't be normal. Anyone else having this issue? I have driven ford trucks forever and never had this happen. It seems the rubber material used is not sturdy enough.

 

Mine did the same thing. Took it to the dealer and they ordered a new piece. They installed it and it is fine now.

 

Hopefully mine will go as smoothly. Thanks for the feedback.

 

Just noticed mine last night. Looks just like yours. 2016 SC build date 2/16

 

Looks like it's all one piece which is part of cowl (left side and right side). Just went out to check mine. It still sits against the window but not completely flat on the drivers side like it is on other portions of the seal. I'll keep my eye on it but it sure doesn't look like a big deal and very easy to replace.
