Wow sorry to hear. Mine’s been at the dealer since Dec.16th. You and a few others mentioned trim lok, can you provide a link which piece you are ordering? I’m also wondering how good a job will be done with mine. 

Search Trim-lok on Amazon... it’s where I got it. I ordered 1/4” tube and 3/8” tube... it’s just the round core tubing... see pic

Well my 2019 early build leaker was replaced with 2020 hopefully not leaker. No signs of an leaks on the window or headliner of the 2020 so fingers crossed. Very impressed with the 10 speed after th

No leaker here so can't do a 100% verification, but the problem seems to be with the spoiler design, regardless of weather the sealer leaks or not, and any cracks in the trim make it worse.

This really sucks. My 03 2500HD with almost 300,000 miles doesn't leak. I would expect it from that. It was leaking on the front passenger floor in extreme rain. Turned out the drain in the bottom of the left fender was plugged. It filled up to the HVAC system. I cleaned it out and no more leak. Good thing since it has no space in the garage now. So it goes in the RV shed with the RV and the Jhon Deere. The Jhon Deere has to be in the middle as it will go past the trailer tongue. It's the only way everything fits and the door will close. So I tend to leave the truck outside when the tractor is being used. It's also not a push the button door. So if I will be using it again the next day it's easier to leave it out. I normally don't leave any vehicles outside. But it is fenced and gated rural property and if it is up by the garage you can't see it from the street. So I think it's pretty safe. And it is right under a security camera.

Big test tomorrow. Leak was sealed at dealer using a glass company last week and it's actuality supposed to rain in SoCal Sunday and Monday.

Guess who is going back to the dealer for a second round of Fix the Leak. 

 

Called another dealer in the area, Hardin Buick GMC, and they said they had never heard of the issue with leaking window. Was told since Tustin Buck GMC attempted to fix it once, I need to take it back there.

Think GM is telling dealers to get past the 3year/36,000mile warranty. Why hasn’t GM come out with a better window? Can’t be that complicated to find a solution that works.

It seems the better window is the non sliding one. But yes, why can’t they look at the last model and say how did this one not leak?

Tell them to check it for leaks AFTER they are done with the "repair" Soapy water sprayed on the outside of the window frame, a little air from the air hose nozzle blasted at the inside of the window frame top and sides better not produce bubbles. If it does.....they have failed. It must pass the test prior to being returned.

Hey everyone, Just saw this thread and went to look at my window and I'm also a winner of the leaky rear window! Anyone who live in Socal have a dealer they taken it to that have knowledge of fixing this problem? I have a 2021 GMC Sierra and I can't believe that this been going on for 2yr and GM haven't addressed this problem.

Most of us CAN believe it.  It's typical of GM.  And some other manufacturers.  They just try to Band-Aid fix it until the warranty expires and then say in essence: "screw you, not our problem anymore." 

At least that is how I see it..

      Towing In Loose Gravel

      By KARNUT · Posted

      First off use it in the way you’re more comfortable. In working in off road situations most of my life I used 4WD low range very little. In most cases when equipped I used auto 4WD. If I wanted maximum control going up and down very steep terrain  I used low range. Especially if I was driving a diesel. Same with very rutted terrain. In very muddy or snowy conditions I wanted momentum so high range worked well for that. With gravel ramps with limited traction I would try high range first. I would want smooth even increasing speed if I was fighting traction. Low range could give you too much to the wheels breaking traction trying to move.

      Towing In Loose Gravel

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.
