Same problem with our 2008 Indiana. I intend asking our dealer to replace the window under warranty at first service, but as this problem seems to have been going on for a long time affecting numerous makes of caravan, I wonder whether the same thing will just happen again? Or has the manufacturer come up with a permanent solution?
By the way, the only other problem we have had so far has been a faulty battery charger. I'm generally quite impressed with Bailey build quality - given the number of gripes so many users of this forum seem to have with new vans!
