Recently purchased a 2015 Yukon Denali! The overhead console leaks during heavy rains! Dealer Has not stopped leak after 3 attempts! Basically acting as if there is nothing wrong!
Here's a possible list:
1. Shark fin antenna gasket - pull down head liner and have someone hose that area.
2. Plugged sunroof vent lines - blow gently with compressed air
3. Leaking sunroof - again, pull head liner down and inspect when wet
4. Windshield replaced and not properly caulked - remove head liner to look ar when wet.
Basically, you need to drop the head liner, jump inside and have a helper hose down the truck - METHODICALLY. Don't just pretend it's are car wash water fight. Hone in on certain areas until you know it's dry or not. Not easy, I know, but doable.
