My '07 Yukon XL Denali has been leaking from through the headliner just near the rear cargo door on the right. There's a water stain on the headliner. Sometimes, the water even seems to come through the vents on the side below and it leaves a puddle anytime we have significant rainfall. I've opened the rear door a time or two and saw it not dripping but pouring through the headliner and out that side vent... Not many places it can leak and come through those places, so I'm figuring a gasket around the luggage rack maybe?
Any other ideas, experiences, suggestions?
