I noticed I got some rattling on my driver side front window when it's down a few inches. I decided to inspect it and noticed that I'm able to push it in a bit with the window all the way up. The passenger side pushes in, but a lot less. Is this normal?

I pushed the panel in and it seemed to help a bit as far as the depth I'm able to push in. I'm just afraid of something like water getting in the door between the window and molding.

 

Btw, my wife's 2012 TL windows have virtually no give at all.

 

2015 new MDX here, all 4 windows seem loose when partially down. When I go over bumps, they rattle. Is this normal? Are everyone's windows loose? I've never had a car with windows loose like this. Just wondering what others have before taking to the dealer.
