[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.

Thanks for the post about the recall. I'll definitely make sure this recall is addressed on mine.

There is a service bulletin for the roof water leaks , all it seams to be is longer drain hoses , I’m waiting for the parts to come in for our 2021 Tahoe now

Hey so we got our 2021 Chevy Tahoe LT in November 2020 and we have had a leak only on the passenger side front. Could this be part of the issue? I took it in last month and they checked and blew out the tubes or something and said all good but apparently it is not. This is not ok for the price of these vehicles.

So they told us it was a tube near the front engine firewall had a crack. They fixed it but still going to keep an eye on it

Any updates on what the actual issue is? This has happened twice to me now, since I bought my 2021 tahoe over a year ago. After a rainy night, i'll go out to the Tahoe and start driving to hear water sloshing around and then comes pouring down thru drivers side seatbelt housing and drivers side foot well. (similar to what was stated above). Just wondering if the issue has actually been identified officially.

My issue was not that serious. They replaced a tube and I hope that has fixed the issue.

gotcha. thank you!

Does anyone have the solution? Is it longer drain tubes or not?? No one seems to report back that the issue was solved!!

My issue was resolved as far as we know. It was the tube and a crack in something.

The dealer finally fixed my issue after going in a couple times. It was the drain tube. It’s common enough of an issue the dealer should know about it by now and will replace for free.

My dealer refuses to believe it is the drain tubes!! I have given them all the information, even the pictures provided by another poster, and they say the drain tubes are fine. My car has been in the shop for over a week now and they are investigating the frame of the sunroof and seeing if the luggage rack screws are somehow causing the leak.

I believe my car only has this issue when I park on my driveway at a slight (~15°) angle, and it rains fairly heavily. So from what I can tell, the issue should be the green drain tube in the back - not the ones in the A pillars. But the guys at the dealership believe the drains are working fine!

We all have/had the same issue. Tahoe parked at slight angle, rainy night, water comes pouring out the seatbelt housing and drivers footwell. All I can say is my dealer replaced the drain tube and I have had zero issues since.

Thanks. The dealership wouldn’t believe me that it was the drain tubes, so they re-mounted the frame and they believe it’s fixed now. Unfortunately I’ll have to wait for a good rain storm to find out. I’ll try to use the hose, but I don’t think it’s going to be as effective.
