Weather stripping

I have searched the site and can't find any info on replacing the weather stripping on my 2013. In a couple of places the stripping is kind of crushed and out of shape. I can hear the wind blowing pretty good when the window is up. Has anyone replaced this and is it a pain to do? I'm talking about the stripping that goes around the cell, not on the door it's self.

I attached a couple of photos.
