2008 G37 coupe

When rolling the windows up and down, the window scrapes and you can see the tint is marked up. On older vehicles, this is very common. I've searched and searched but haven't found anyone talking about this issue.

There are adjustment points for the front and rear of the window for height but nothing else I can see without pulling the door completely apart.

Anyone know how to fix my issue or can point me in the right direction?

 

Same issue here, it just started happening on my 2011 G Coupe, if anyone has any advice or know how to solve it, please let us know

 

Would lubricating the seals with lithium grease help?
