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.

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 :)

      Some Assembly is Required

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
