22 Tahoe with Water Leak

[2022tahoez71]

2022 Denali here, been in 4 times for same problem, I have water running onto drivers side floor from under the dash, only seems to be when truck is parked with drivers side lower than passenger side. They can’t figure it out…. I have a case opened with gm, also since they dropped my headliner I now have head aches when I drive the truck, I think they messed up the active noise canceling system, has almost a low drone sound or buffeting in my ears, and the truck shakes in the backseats while driving, nobody can fix anything…… best 85,000 I’ve ever spent… smh

Same exact issue!!!!!

I just took out the overhead console and found the same small holes in mine. This appears to be the source.

I see at least one of these a month, if not two. Best case fix is to pull the windshield, and put sealer over the exposed spot welds while it's out.
I have tried fixing one with some spray sealer by sticking the little straw/tube between the rubber and the roof so it'll get behind the windshield, and it did work, but I prefer to just recommend the dealer have the glass pulled and do it right since they're all under warranty so far.
And hello everyone, I'm the guy in the video above, saw it was getting most of its views from this forum so I came to check it out.

Thank you so much for making this video. I hope it goes favorably for me after I show it to the dealership. I was wondering if after you fixed these problems did anyone return for damages caused to the electrical components in the overhead like the lights malfunctioning or not working or onstar button issues?

@Pacfanweb Have you seen it when it leaks in the rear? My 'hoe' is normally parked in my driveway with the front wheels higher than the rear. Last night it basically rained in my car through the passenger rear AC vent. Then it fills up and when i start to drive and if I brake hard it runs forward and comes out of the middle seat passenger ac vent overhead. I've taken it in 3 other times for the leak and they can't find it.

Do you have a sunroof? If so, it sounds like the water is not getting to the drain lines for the sunroof rain tray and jumps over the lip. Open your sunroof and look in the corners where the drain lines are located and make sure they aren't plugged with debris.
