My window seal is started having this problem on the passenger side around 8000 miles, which is strange because obviously my driver door is used more often.
I tried lubing the seal with EasyLube+Wax bike chain oil. That made the problem worse. I took off the lube with warm soapy water, and now I'm back to square one. The problem is obviously that the rubber on the seal has been worn and has too much grip. If you run your fingers along the seal, you will feel that it's nice and slick until you reach the problem area, which is very tacky feeling.
My dealer is really cool so I'm confident they will replace the seal for me. Windows are not tinted.
