Update. The factory missed Over a foot of sealant in the rear window. Waiting on a new window. Dealer decided to just replace the entire window and have a glass guy do it. I’ll give credit to the service department for doing this.

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.

2019 Silverado 1500 LTZ (Black Ops edition by Tuscany). 

Not sure how to check when it was built but according to my VIN it was in Mexico.  I cant seem to find the date on the door.  

 

I joined the leaky rear window club yesterday morning.  Well probably before then since I had weird moisture building up on the interior of the cab and for some reason my windows just kept getting fogged up so easily.  Driver side is leaking pretty good, passenger side is a couple drips. 

I called the dealership and I'm scheduled for Dec 18th and they wont let me have a loaner.  They want to charge me $35 a day to get a rental car through them.  I opened a case with GM already.

 

After reading about 120 of the 173 pages here, I'm tempted to do the silicone fix since I'm pretty good with shipboard electronics and use the marine stuff already.  I'm just not too familiar with cars/truck maintenance repairs if its not an oil change or tire change.  I'd also have to rent a dry space/garage since my truck doesn't fit in mine. 

 

I'm really concerned with water getting in and since its freezing at night here in Washington it will just cause further damage.  Which I suspect is what triggered the water to be large enough for me to see it now.  I've got a waterproof truck cover on its way but its going to be a huge hassle taking that off and on if I want to drive the truck and now on rainy days I need to leave it covered at home.  I feel extremely robbed of the new car/truck experience from GM.  I really wish there was a recall and permanent fix from GM already.  I love the truck even though this will be the second time in the shop(a front left shaft broke already, J, F, or S, I don't remember but I still have the paperwork).  I've owned the truck for 4 months and its spent 1/5th of its time at the dealership and with this it will only extend the time spent away from me.  

 

 

Edit 1, Dec 3rd:  Changed dealerships to fix my truck.  Going 30mins further to the next chevy dealership since the tech I talked with knew exactly what my problem was and said he just fixed one two weeks ago and I'm having the exact symptoms.  Still they don't have a loaner vehicle either... its a Chevy Equinox for $35 a day.....  

Update: Dealership has been very knowledgeable and nice with my concerns so far over the phone.  They tried the sealant fix but said it failed their tests afterwards.  They will be replacing the rear window.  They ordered a new window and its coming from the other side of the US so I'm going to have to wait at least a week due to blizzards / shipping.

Can someone explain why it’s so common for the sealant fix to not work? You’re literally plugging everything with sealant, it makes no sense. I can see maybe after some time the sealant shrinks or cracks, but what about this example where they do it and it fails the test right after?

The TSB(18-NA-383....) for the sealant fix that dealerships have to do is only step 1 to prolong this problem out of the warranty.  The next step is window replacement.    The fix so dealerships can get paid is the bare minimum and people have found its a better solution to do it themselves and seal every bolt, crevice etc.  Their fix is one bead line.

When I pulled my spoiler off I notice probably 5-6 inches on at the top of the slider where the tech didn’t put any sealant or it was barely there.  Once I filled the whole gap with sealant to the top of the glass all my leaks stopped.  
 

Unless you remove the spoiler yourself, your at the mercy of the Service Advisor to tell you why the sealant failed.

In my case the dealership did a piss poor job by not only pushing the seal in when reinstalling the spoiler but not putting an even flow of sealer along with destroying my interior. I could have done a better job when I was 8 years old. Incompetence is the problem.

Gotcha, thanks. That’s what I was looking for. Seems like the dealer fixes (as far as the sealant goes) is due to them just being bad at putting the sealant on. Also seems like it works way better when done by the owner themselves.

I just didn’t know if I was missing something with the sealant itself having some property to it that makes it not work right. But again, seems like it’s the quality of the sealant installation that is mostly to blame.

Thanks for the replies!

Mine was sealed 2 years ago by the dealer.. Still no leaks. I will never trust it though and check for wetness every rain event or carwash.

Update: Picked up my truck yesterday for the second time. Their “glass guy” came in and confirmed that his previous installation was leaking and he resealed the window... kind of sloppily I might add as there is caulk on the rear glass and a little on the plastic frame by the slider. I’ll get it off the glass but will have to deal with it on the plastic. I asked my service advisor if he did the TSB as well, which I texted him the pdf that is on this page showing what to do, and he said no... he just resealed it. It’s supposed to rain like crazy today and tomorrow so we shall see. Kinda pissed that he didn’t just perform the TSB while he had it apart for the second time! 
 

I also bought the trim-lok in two different sizes that I’m going to install on the gap right above the window and the gap at the top of the spoiler.

Add me to the list 2020 RST Z71 1500 miles leaking from the passenger side trim rail it seems no wet head liner. Truck goes in on the 29th as dealer was booked up till then. Can someone link the TSB for this? I did a quick search and didn't find it attached some pics...Just so happens that GM sent me the Quality survey after i found the leak. Lets just say i let them know just what i thought about their handling of a 2+ year old KNOWN problem. I also had the no start no crank with dic error codes in the first 150miles and they just replaced the battery and did a software update.

With all the stories about people’s service dept experience, I don’t blame you to constantly check.  But I do feel a good sealant job will fix the problem short of GM demanding Fuyao/Vitro to use better plastic for the frame.

      OCI, not when but why?

      By Chuck FB · Posted

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      By teamjnz · Posted

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
