I was wondering if anyone else has had this problem. I have a '07 4 door and have been getting a single grease streak on both the drive and passenger side windows (about 6-8 in. back from the side mirror). I took it back to the dealer and they adjust the window stabilzers bars (I think). They had been rubbing the window leaving the streak. Now I notice that there are scratches on the window in the same place that the grease was.
