Just bought a 2009 G6 Coupe w/sunroof. I have a garage so it hasn't been exposed to long periods of rain yet; but when I took it to the car wash (automatic car wash w/wind blowers), I saw water dripping on the rear passenger side, all the way to the rear where the gray headliner joins the black plastic trim. Now I believe the sunroof issue was fixed on the assembly line for the 2009's; would that be a safe assumptions? If so, could it be the exterior wheatherstrip (black rubber) between the rear window glass and 1/4 panel sheet metal?? Looking at it, I see some gaps and I even see a little bit of black sealant added on the driver side!! The car is brand new with no signs of interior flooding.
Any advice is appreciated.
