The driver side window on my 2012 F150 rolls down, but the top of the glass stays about 1/2" higher than window sill. If I push down on it, it will go the rest of the way down. It is under warranty, so I was going to take it in, but it's gonna be awhile before I can. Is this a common issue?

 

First I've heard of this.

 

I'd take it in either way, haven't heard of that before.

 

Mine did the same when I first got it. After couple months it goes down all the way.
