06 VW Jetta: Front driver side window was stuck down. Call dealership?

The dealership won't take blame for the window first of all. And it sounds like your window my just be sticking. You could always lube the track and hope it doesn't happen again. My window in my truck has done that since i bought it in 2003 and still does it now and then. I spray the track with grease and it works great for another couple years.
