I know this is probably an old topic, but I can't seem to find the thread. What is the fix to this grease problem on the windows? I am seeing little smudges of grease on my tint when I roll my windows up and down. Has anyone taken this problem to the dealer and if so, what was the fix

 

There a TSB (Technical Service Bulletion) for this. Take your car to the dealer and show him the streaks. If he's not aware of the TSB, he can look it up in his system.

The dealer will have to order a kit that fixes this problem. Make sure they order kits for both windows.

 

Here is one of the threads with the TSB.
