On the drive home last night, my passenger-side window slipped its track and fell down into the door. Of course there was rain in the forecast last night, so I had to run out there and get all creative with garbage bags. I went early this morning to try and hit "the dealership":http://www.vwdealer.com/billco/ early and maybe get it fixed. They're always busy there, and I would have had to leave it there all day, but as an alternative they just had the body shop guy pull the window out of the door with a piece of wood and some duct tape, and then tape the window up in the frame well enough until I can bring it in for a scheduled appointment next Wednesday. Apparently this is "a common flaw":http://www.carsurvey.org/viewcomments_review_19084.html with VWs, although the body shop guy said he thought it was most common in Jettas, and mine was only the 2nd GTI he had seen with the problem. Lucky me.
