Rained very hard, and very steady for about 2-3 hours last night. Went to check my window this AM, and she was a-leaking again. Not too bad at all, but the leak is back, like the Terminator. 
 

It was a nice 2 week break with no leaks. Then again, it barely rained those 2 weeks, Lol. 
 

I guess it’s new window time for me.

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.

It took five trips back for GM to finally say a new window would be required. Now it’s backordered and they can’t tell me when it will be available. Good luck. The second caulk job was sloppier than the first.

I miscounted my trips back to the dealership.

And wait till the glass guys have to cut that caulk job off the back of your truck with a razor knife800ecf9d33138c1066aef100a688c35d.jpg

I was in the neighborhood so I did a drive-by at my dealer to see if my truck was outside. I could see a guy moving his belongings from a brand new high country to a double cable LT loaner. That can only mean one thing.....

The seven inch long tattoo they left on the side of the rear window then "touched it up"

Browsing through this thread, if I understand the issues:

1) It appears that two different window manufacturers (VITRO and FUYAO) have been used and both have experienced leaks.

2) Both 2019 and 2020 models have experienced leaks

 

Is there a true fix to the issue? Can this be addressed in a 2021 model?

That exact Vitro window has been used for the last 6 years. Earlier this week I would buy a factory new window on Amazon. It was listed for 2014-2018chevy and gmc

The only thing I haven't seen is someone get their window replaced and then develop another leak. So if that is the case it could point to a factory install issue but it could also be a body flex issue which would not be very easy to address even in 2021. If it was a factory install issue you would think they would have fixed it by 2020 models and it would probably only be at one facility but that's not the case either.

Everyone who has a leak and is able to get a buyback is probably smarter than us....sell the truck and move on so they never know if it leaks again or not!

These new trucks have that much body flex? 

 

If it was the same part used as the last body style and it worked on those but doesnt on these that is weird. ?

I originally posted in Feb 2019. I live in So Cal so we don’t get much rain. Purchased AT4 in November 2018. Leak in Feb 2019 in corners of rear window, my dealer had truck for about 5 days and replaced window. No issues until Xmas 2019, rear window leaking in middle after a heavy rain. Dealer took truck from 12/24 until 12/30. They replaced window again. We’ve had some small rain since, but I haven’t had any leaks yet. I really do like the feel of truck, but am debating on getting rid of it. Is this going to be a yearly thing every winter? How long will they keep replacing window at no cost? Both times they have given me a loaner Yukon so I can’t complain about that, but why does my $50K truck leak? It’s definitely an inconvenience to me and my family as this last leak was discovered the day before we were driving out of town for the holiday.

Well, there you have it folks, a previously replaced window that leaks again. ??‍♂️
 

The answer to your question is they will keep replacing it until it’s out of warranty, at which time it would be wise for you (and all of us) to dump these trucks as fast as we can...

 

For anyone still thinking the 2020s will be any better at all...just saw this posted...original TSB has been updated to include the 2020 half tons and HDs. Admission the problem still exists I guess.

It will be interesting to see how many HDs have the leak by this time next year. Presumably the chassis is much stiffer, so if it’s a “flexing thing“, we may not see very many of the 2500/3500 trucks with this problem.

By no means am I trying to debate. I have been following this thread very closely, checking my window every time it rains (even lifting up the seats and checking the bolts for corrosion). If it’s body flex, wonder how many of the people that have experienced a leak use there truck for just a DD with mild driving conditions? In other words what situations would have caused their trucks to leak in the first place? Not sure if I am stating it correctly? I know I take my truck off the beaten path....

 

I love this truck but between the leaking windows and brake issues, it has me a little freaked, especially since it looks like GM doesn’t have a definitive fix for either

      Gas Prices

      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?
