I have a 2008 Smart and I'm having problems with water leaking into the rear hutch. When I open the rear window water gushes down the left side and trickles right into the hutch. It must be collecting because it happens even when the weather is dry. Very annoying! Especially now that my extended warranty just expired… I called the dealer in Denver and was told that it is a common problem; they have been drilling holes in the window area to get the water to drain out.. is this something I could do myself? My boyfriend is a carpenter!
