Sunroof Drain Clogged

dirishlad · Apr 28, 2022

I have a '21 Tahoe Premier and after a heavy rain I had water coming out of the seat belt opening and where the mirror is attached to the roof. Does anyone know if clogged sunroof drains are under warranty?
Thanks

Yes it is. It may also be a kinked drain line, that also is covered.

Just curious…the seat belt opening, is that in the 3rd row on the passenger side? That’s where I’ve got a water leak…drips on at the bottom of that 3rd row seat belt.

I am not so sure that a clogged drain is a warranty item, but worth asking. I've had good luck taking some larger diameter string trimmer line and fishing it down the drain line to get any kind of debris to clear out.

Might not be a clog. Ours leaked onto the driver floorboard and the dealer used this tsb to fix the issue. There's also reports of the drain tubes not being properly connected so the water ends up inside your headliner...

No mine was the drivers side seat belt opening-pouring out of it.
