2015 Yukon Sunroof Drain Problems

[Carlin Chapman]

Every time it rains heavily I hear water in the area surrounding my sunroof! It sounds like a gurgling of some sorts like the drain is clogged. I've looked and cannot find any drain hole or tube. Has anyone ever experienced anything like this? It only happens during a strong downpour or when the truck has been sitting in a down pour.

Can happen a lot. There are 4 drains, one on each corner. You can try to blow it out but be careful, as sometimes the air pressure can knock the hose off the fitting. If that happens, its time to drop the headliner. Should be under warranty still, no? Bring it to the dealer.
