A friend of ours works at the Fort Wayne plant, and I heard him mention that they had engineers there at the plant for several months trying to figure out the issue and how to fix it. I didn't ask him whether they ever think they found a fix, but based on this thread, I have to assume they never did. I will have to keep an eye on our 2020 Denali and I wish I had known about this before our purchase. :(

It would be great to know, but yea the latest builds are still having these issues, I think there was a 2021 in here with a leaking rear.  Had to be 9/20 build or later.  Let us know if you chat with him again and can get any other information.  Several months is a long time lol...

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.

Is the Trim Lok cord that others have used too large in diameter to push in around the rear window.  Was thinking of trying that instead of caulk or sealant due to the temps in PA right now.  There seems to be enough of a gar around the window to do it.

I purchased the one someone linked to on here and it didn't work for me. I was able to get it in (between edge of glass and body) but once in, the gap between the back of the glass and frame was wider than .25 inch.

I would go to their website and find one that will fit that gap. The one that the other guy linked on here was for the upper gap of the spoiler. I'm sure they have one that will fit the bigger gap of the window. Then you can go to a place like Home Depot or Levine's Auto or something and find that bigger size. Might work... Here is the link to the website of the people that make all this stuff...

Thanks Dali555.  I am going to check that out, and see if I can Amazon a slightly larger diameter size.  With a black truck I don't think it is going to stick out like a sore thumb, at least as a temporary solution.

Got my truck back after a week and a half. I’ll have to take a better look tomorrow as it was dark when I picked it up. I’ve attached a pic of the new glass numbers as well as the top of the frame and a pic of the old frame... slight difference

Nice to see some physical changes being done to address the issue. Hope it’s the fix everyone’s been waiting for.

Looks like the same series as my 06/20 build:

The frame looked to be a little thicker when I intitally looked at the OP’s pictures. No?

I guess I have been lucky. Mine is not leaking. And I live in rainy Seattle. How do you know the build date on the truck?

This is the first time I've seen the FUYAO E4's without the "wing". Historically, the FUYAO E2's did not have the wing, but the FUYAO E4's and the VIRTO E9's did. 

If that is the case, then they are mixing glass versions with frame types.  ???

Is the wing the "redesigned" part?

Interesting. My E2 has a wing but it looks different. 10/2018 build. Goes without saying that it leaks. ?D1653685-F820-4593-9F39-56ACBBE9BE4F.thumb.jpeg.e528d1203a1eecc06218cd48b0e13e8e.jpeg4C03E1EA-A17D-4558-B20C-26F9CACF3907.thumb.jpeg.ed79e7c7d109503f2a2b306be107686e.jpeg

No, the wing is my original window and the other is the new redesigned window.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
