Can anyone else replicate this?
I had this problem. The drivers window doesn't seal properly. The dealer added expanding foam tape around the window guide to make this stop. They will also remove some foam from the vents in the trunk to reduce interior air pressure. Unfortunately placing the tape requires removal of the metal exterior trim, which will bend. So they'll have to order new trim for you as well if they go this route.
