Same problem ... My Ion Quad Coupe Redline is Fixed!
Hi Ö I had a similar problems over the last 2-3 years, where the sunroof would leak either in the rain or a car wash. I discussed the issue with my mechanic, who now works at a Chevrolet dealership after specializing on Saturn at a GMC dealer. We decided to try "clearing" the sunroof drain channels, because nothing else seemed to be causing the problem. He indicated that there would be no guarantees Ö but it worked. It has been over a year since his work, and the car has been thru rain, snow and car washes Ö not a single leak! For those in So Cal ... Simpson Chevrolet in Lake Forest ... ask for their Saturn specialist.
