22 Tahoe with Water Leak

[k1970]

Sometimes I have the same, but at the rear glass.‍

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.

I do have a sunroof but the drains work fine. Thanks for checking.

Thank you! That is exactly the issue.

Hi. How did this end up for you ?
I have identical issue with water coming in same spot. Right side of headliner. Now little on the left too.
3rd time going into dealership. Supposedly a GM engineer is going to check it out.
Just wanted to know how yours ended up, if it was fixed and what the actual issue was.

Ok so we pinpointed that water only leaked in when the front wheels were elevated (parked in my driveway on a pitch). During driving i had no issues. The front drain lines worked fine and when driving could drain the whole roof as needed, but when it was parked and the rear drain lines had to compensate and drain the whole thing is when it would leak in. So the dealer really focused on the read drain lines and found them to be pinched from factory. They ordered new lines and replaced them and we have had some very big storms here in Maryland and NO LEAKS!! Tough problem to solve, but once they got it tilted they found the issue.

Wow. That’s great to hear.
They called me this morning. Claiming that last time when they sealed the pinhole in a spot weld. That they didn’t seal the windshield entirely.
So they’re bringing a windshield company in to reseal it and they think it’ll finally be fixed. Heard it twice before, but we’ll soon find out.
Glad to hear yours is all fixed.

Mine ended up being resolved after the service department filled in the spot welds.

Damn that sucks.

We have the same issue? How is this not a recall? It is clearly a factory defect and a result of poor quality control. I BELIEVE if this does not come out as a recall then we have enough people here to start a class action lawwsuit.

What would be interesting to know is when the last time the spot weld machines were last calibrated.

Nope. I avoid any type of sunroof equipped vehicles like COVID.

Came to post about our CPO 2021 Yukon. We just discovered a water leak issue back in November. Thought it was from a small cooler we used on a road trip, but in late December found more water again in the passenger front footwell. I pulled some trim and carpet back and found evidence of water streaks down the firewall and the source of my bad smell in the truck. Thought someone had spilled milk, it was mildew. Dried and vacuumed it all up, took it to the dealer and they had a leak specialist look into it. They told me they resealed the windshield and it's on my invoice, but I didn't see any evidence of that. They probably didn't pull the glass and pulled trim and caulked? All I found some black rtv on the passenger door weatherstrip at the bottom though which was a half assed attempt. So I was already skeptical of the "repair."

A few weeks later, truck is just sitting in driveway out in the rain on a slight incline facing uphill (very slight) and I had wet carpet and water running down the firewall. Wife had to go use the truck so I put some towels under the carpet. They were soaked when she came home. This time I got pictures a short video. Took it back, and they had it for a week and couldn't recreate my leak somehow. We had a day of heavy rain and flooding, and it didn't leak for them. I'll be collecting more data on if it's worse while driving, how we park it etc. I'm sure this will take a few more trips to the dealer before its resolved. I'm going to pop my overhead console down this weekend to look at those spot welds for evidence of dried up water. I'll make sure to reply back after some time with what happened and if its indeed leak free. They may have shot some rtv around the windshield over those questionable spot welds, who knows.

My Ram did that when I had it. They replaced the windshield westherstrip and the third brake light weather strip
