22 Tahoe with Water Leak

[Cryptocap]

Well, it was raining both outside and inside my Tahoe. I took it to the dealership, so now just waiting to hear back. seems to mostly be on right side. I was parked facing downhill when it happened. I turned it around to park uphill and it stopped.

Damn that sucks.

Sorry to hear that. This is pretty ******.
My 07 G6, 09 Silverado, 16 Yukon all new all leaked in that area. Sunroof and antennas suck for GM. Really had hoped they would have fixed in this new style. Dealer should fix under warranty and it's the last you see of it. Least that's what's happened with my 3 vehicles.

That’s a sigh of relief… the fixing it part.

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

Find another dealer. Or trade the vehicle in. Why deal with the head ache? Both literally and figuratively.

We used to have showers at my dealer that we would park the cars under until it leaked. Worked great and easily everytime.

Had chassis ears for rattles, squeals and abnormal noises.

Sounds like your place just isn't cutting it.

Several threads on this already.

There is a TSB out for a disconnected drain line if you have a sun roof.

Ours went in for water on the floorboards around 3k miles. Turned out the sunroof drain tubes were too short at the bottom and water was not properly draining out under the vehicle. They added extensions as per the tsb about this issue and it's been good ever since. Just passed 21K miles

Tested the drainlines already those aren’t the issue.

Nice. Glad that worked! They looked at that TSB but doesn’t apply to mine since it applies when the vehicle is moving. Mine happens when parked.

What did you end up doing? They dropped the headliner on my and still can’t find the source. I opened a case with GM but need to take it back in a couple more times.

Same exact issue!!!!!

Thank you! That is exactly the 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.

 

[Cocotahoe]

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?

Nice video! That's helpful.

@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.

Same exact issue!!!!!

Consider the body seam weld ab the sun visor:
