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

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      By Grumpy Bear · Posted

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
