Just talked with the "new" dealership dealing with my truck after the last dealership nightmare of two tries.... last night I texted him that I would like the TSB performed regardless of what his glass guy finds that is causing my leak. I told the previous dealership that TWICE because it was already taken apart so they might as well do it. The first time they replaced the entire thing, didn't do the TSB... the second time they "resealed" it, didn't do the TSB... this new dealership texts me back today and said they already performed the TSB and sent me a pic of the sealant on the top AND said that the window wasn't causing the leak but that the clips holding that stupid spoiler was where it was coming in. He sent me a pic of the old style yellow plastic clip and said they changed styles... all GMC did was add a gasket... and sent me a pic of the new clips they were installing. When I get my truck back I will wait a bit and see if it leaks... if it doesn't then I will add the tube gasket I mentioned in a previous post here to the spoiler gap on top and to the gap between the spoiler and the window frame. HOPEFULLY, I will finally be done with 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.

Was you headliner getting wet every time it leaked?  Mine drips off the rails, but the headliner seems to be dry.  I may give the dealer a call and at least discuss it with the Service Advisor.

No, my third time the drips were pretty minor and just dripped on the top of the seat....

Got my truck back this morning.  They originally started with taking the spoiler off and applying the sealant.  They confirmed this didn't fix the leak and kept the truck longer for a replacement window.  So far so good, no leaks but its only Day 1.

Has anyone explored installation of this aftermarket Power Slider sold on eBay?  I contacted the seller and they claim it fits the new 2019+ body style.  The design is interesting as it looks like the plastic slider track is mounted lower, allowing for glass to body contact around the entire sealing perimeter of the window.  Rather than trying to sandwich the plastic slider track (known to crack) between the glass and body like the OEM GM design does.

As I have said before the aftermarket will fix this. They see money to be made. Now several companies will compete for the best fix. I hope mine holds up until there are several choices. Then I will just pay to fix it right.

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

I've had my 2019 now for just over a year and took it in last week for the third time with this issue.  The first two times they resealed it and called it good.  I told them this time I wanted the window replaced, and I now have this same version.  The tech notes say "The rear glass separating from frame".  I didn't get to see the old window so I can't verify exactly what it looked like but if this is accurate then it appears there may be another issue other than just the cracked frames and failing sealant.

The plastic frame is glued to the window so even if the top is sealed real good eventually the frame will separate from the window elsewhere. Solid window is the best way to go to avoid future issues.

LOL. A 2020 or 2021 2500 Silverado. With any luck I'll be able to lemon that one too (they are still leaking and still documented cases on 2500's with build dates as late as 9/20.)

My 2020 2500 built 8/19 is also leaking. Just noticed it over the weekend. Small drips in the upper corners of each side, then dripping on the top corners of the back seats, also has stained the corners of the headliner.

Has anyone filed a formal complaint with the NHTSA? I have pasted the link to the form below and also NHTSA's website where the form can be found.  Their website lays out how complaints are handled and used to determine if a recall is necessary.  I feel like if we get enough people to file a complaint, they will investigate the problem.  It is a possible step to having a recall issued.  The fact that so many people found this thread and then went check their trucks, tells me that there are probably a large amount of people that don't even know they have a leak until it gets bad enough to start smelling of mold and mildew. Mold inhalation/toxicity is a serious health issue, but in most cases is overlooked and misdiagnosed. If enough cases are approached from this safety standpoint it should create enough attention to have a recall issued.  Thinking ahead not only for ongoing issues for the new trucks, but as these 2019s are traded in and bought by more unsuspecting consumers who may be out of bumper to bumper warranties and who will be affected by this ongoing issue. 

Lets spread the word and get as many complaints filed as possible.

Sorry if this has been brought up already.  New to the leak club.

How many of you have or are in the lemon law process? If so what have been your outcomes? Good and bad. Thanks!

We have had a lot of rain here lately. Everything from down pours that are causing flooding to light rain. I keep checking but still not leaking. Although yesterday and today I will be driving the old truck. We had a massive wind storm night before last and there is stuff all over the roads. I don't want to risk scratching the black paint so it will stay in the garage.

Hi - I am writer for the Detroit Free Press and I see a lot of complaints about rear windows for Chevy and GMC pickups. Would anyone be willing to talk to me? [email protected].

Another update.  Its been a few weeks.  Lots of rain here in the Northwest and still no leak after the window was replaced.  I took it to the self car wash(it needed it).  Soaked the top and got it all shiny again.  I didn't find a drop inside.  I hope it stays that way :)

      OCI, not when but why?

      By Grumpy Bear · Posted

      I understand. It is disturbing to think a manufacture asks so much and gives so little in engineering support. This is not a GM issues, this is a greed issue and one the ALL practice.    My intent was not to remove the wind from anyone's sail but rather to point out the areas deficient so that they can be discussed with improvements the goal. But to do that you have to know the truth and what that truth is.    The commercial interest are honed in on a few select issues in which they control all the variables and are not forthcoming in the least with their customers about the details. Failure is the only thing that drives these people to improvement. One way not to fail it to manage public "expectations". The set a bar they can clear and put their thumbs under the suspenders with chest puffed.... Only the internal data tells the story fully. As we don't have access to that for decades then we have to generate it ourselves. UOA's with data that matters.

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...
