[2021Premier]

Just bought my 2021 Tahoe premier 3 weeks ago. We test drove it and fell in love with it. A week later we noticed rain water coming out of the seat belt housings on the pillars of both the front and second row passengers. We could also hear the sound of water sloshing around over head. I just brought it into the dealer this morning for them to investigate the leak when they notified me of a engine oil cooler line recall. Apparently this can cause catastrophic engine failure.
They said that they inspected the oil cooler lines and they’re ok. When I asked about the water leak they said that they blew air down the drain tubes in the sunroof. They said that sometimes they can become clogged or pinched and they look like they are draining properly. They then said that if it happens again then I need to bring it back and they’ll have to drop the headliner and inspect it.
I have a feeling I’ll be back.

Here is the link for the recall they found:

TSB Issued For 2021 Chevy Tahoe, Suburban, GMC Yukon, Yukon XL

The bulletin addresses a potential issue with the engine oil cooler lines.

I’m having similar issue curious if they figured out the leaking and sloshing issue

 

[2021Premier]

They haven’t given me a definitive answer yet. We haven’t had much rain since this happened last. We should be getting some rain next week so I’ll keep you posted. If we don’t get any rain I may try and soak it with a water hose to try to recreate it (something they should have done instead of just blowing air in the drain tubes). I really don’t want to get water in there again but I’d rather find the issue now rather than later.

I have taken mine twice within a week and have gotten no answers. Just bring it back if it happens again. Super frustrating

Did they fix yours yet? Any pics?

 

[2021Premier]

I haven’t had mine sit out in the rain since the first leak. We haven’t had much rain at all since. I did however soak the roof with a hose yesterday afternoon. I couldn’t find any signs of the leak. I know it’s not as good as letting it sit out in a downpour but I thought I’d test it out anyway.

They told me the first time the drain wasn’t connected, fixed it and then a week later the carpet was wet again. When I took it in they said the carpet was still wet from the last repair and they didn’t hear the sloshing. Told me to bring it back is it happens again!

I have a 2021 Tahoe High Country. Water is coming into the cabin somewhere and getting driver side and rear floor soaking wet. After spraying the roof (sunroof) with water it appears to be coming somewhere and pooling in the 3rd row floor board??? Have an appt at the dealership tomorrow morning. To be continued........

Interesting to read that others are having this issue. I’ve had my 2021 Tahoe for 17 days now. Had a couple of days of rain since then and I noticed the same sloshing noise but haven’t found any water coming in. I immediately brought it in to the dealership and they said that after it rains I should turn the air conditioning on max to use the pressure to trigger the drains to drain the water. I am not happy about this and do not call this a solution. Currently working on switching my Tahoe out for another one that doesn’t have water problems. I don’t have time to dealing with this.

The dealership called the the same day and advised the driver side sunroof drain tube wasn't properly installed at the factory and therefore each time it rained water was coming into the cabin at the 3rd row floorboard.
Dealership has given me a 2021 Tahoe loaner and stayed the carpeting would be replaced under warranty. I have a case # opened with GM corporate to see if they'd repurchase vehicle since it basically has water damage (and for future wiring after warranty). Tahoe costed $85,000 and only has 3,800 miles😵😵😵Haven't heard back yet. Anyone have a corporate contact???

Wow. The service manager at my dealership was contacting GM yesterday. I’m calling tomorrow to follow up to see what has been said. If they aren’t eager to make this right very soon, I’ll be going the lemon law route. I didn’t pay a defective price for this defective vehicle.

This sounds exactly like what happened to me. My truck is still at the shop on its second go round for the leak. Its been there for 10 days now.

Just got mine 3 weeks ago and took the all weather floor mats out for the first time today. Unfortunately, the driver carpet was soaked. I’ll have to take it to the dealer on Monday and see how this plays out.

Hi There - I just experienced the same issue as you described with our 2021 Yukon. Wondering what the outcome was? Hopefully, it was simple and they got it taken care of for you! Thanks

If you looked into the specifics of your local lemon law, mind sharing it with us here?
Curious to see at what point it can actually be used. Might be helpful for others here too.

2021 Tahoe roof leaking - looks like a lot of people are having same problem. I had a waterfall in out Tahoe with water coming out of the seatbelts and overhead console. Dealership was like bring it in and it could be three weeks before we get to it. Oklahoma hudiburg Chevrolet

 

[brich21]

I have the same problem. Just purchased my 2021 Yukon Denali 3 weeks ago. I left it out in the rain last night and when I pulled it into the garage water started pouring from the headliner in the back seats and down the side pillars. I am taking it back to the dealer to fix this week.

I have seen some of you post that the drain tubes are to blame for this issue, however even if the drain tubes were blocked or pinched the water should not ever be able to make it into the interior of the vehicle. It should just pool or run off the top of the vehicle. There has to be a faulty seal from the rain gutter or tray to the drain tubes or the seal around the sunroof is failing.

Curious to see what came of your issue. Did they replace your vehicle due to water damage? I, too, had water come in from the sunroof on my 2021 Tahoe. Started 2 mos ago and water poured in through the roof console (where sunroof controls are), then through the rear passenger dome lights. Noticed water streaks on the front door jams. Could hear water sloshing above cabin. Put in shop for 3-4 weeks where the removed headliner, had to replace the sunroof and ultimately the motor in the sunroof cover after it was damaged by water. Morning after getting it back, when I cranked it, I had no electronics-no backup camera, no touch screen, no radio, no driver command center (in dash behind steering wheel)--all blank-non operational. Took it back but with holidays, no one was available to determine what they were going to do. Picked it back up & have had the electronic failure twice since. I fear it will never end--who knows how much water went into the dash or could have affected the control panels/computers. I, too, have asked for GM to replace it. Back in shop now & they are working toward that but GM doing every conceivable test, diagnosis to keep from having to replace. Thankfully, the dealership owner is involved and advocating on my behalf. What a mess.
