Anyone else have a 2007 Cobalt SS S/C that is leaking water anytime it rains or go through the carwash in the rear driver side window? noticed this everytime now and is draining into the trunk and under the back seat. Taking it to the GM garadge tomorrow.

Sounds like you got a bad seal. warrenty covered issue :) if you still have one.

I have the same problem. I have water leak from rear passenger front and back. It can be compared to a flood coming in.

Yeah I have it too but I think it has to do with my sunroof and unfortunately I'm not under warranty anymore. I have to repair the frame on the sunroof anyway so I'll dig in and find out why this is happening.
