What i should have asked is, how many of you all have had there rear window replaced just for it to crack again? 

They redesigned the frame and track for the slider window. The made the plastic thicker. The new design windows don’t seem to crack. Which is why people are realizing that the window frame is not the only source of water leaks. 
 

I got an update on my truck Friday and they said they have narrowed it down to the spoiler bolts in the middle behind the 3rd break light.

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.

I didnt know that, so maybe i will get it installed then, if it ever comes in. 

 

Do you think the one i have now will get worse over time? Its not leaking at all spolier or rails. 

 

Hopefully they get yours done soon man its so frustrating. I opted to do the work myself. The man said it wouldn't void my warranty and i have a little bit of experience.

I’m my opinion. If it doesn’t leak don’t change it and give it a reason to leak.

Yeah thats what ive been debating. I'll probably just keep my orignal window i don't want my interior messed up.

 

 

Good luck with your truck man, if the dealer cant patch you up, let me know and ill tell you what i did step by step.

Yeah, leave it alone. As someone who has had the TSB done and finally a full replacement, and most of my interior panels damaged in the process - it’s not worth it. If it’s not leaking now and you have your 3/36 warranty - just get it replaced closer to 3 years while it’s still under warranty and likely they’ll have a better fix down the road.

So we have finally found the source of the leak in my truck. I went to the service department yesterday to get an update and they took me back and showed me. 
 

on the line of body seam sealer that was applied at the factory by the robots which sits directly under the spoiler there was a air bubble in it that popped. This was filling with water and then leaking through the seam to the truck. You can see it in the attached pic. 
 

what they did was filled the void from the while with flexible dealer and then are also sealing it on the top also.

It’s been pouring all day. My flowable silicone repair is still holding. No leaks YET. However I did notice cracks in the plastic now. I was leaking at both corners before I did the silicone job.

That’s great that it’s holding. In my opinion it’s holding because the cracks are not the source of any of our leaks. Mine turned out to be a popped bubble in the body seam seal applied at the factory right under the spoiler. I think it is just a convenient coincidence for GM that the frames were cracking. 
 

the TsB never stops the leak because it does not address the true source of the leaks.

My 2500 is beginning to leak near each corner. I took it to the dealer and they tested it and have ordered a new spoiler/brake light/camera assembly. Said once it arrives and gets painted to match, I can bring truck back to them for install. They've been great so far, keeping me informed as it goes.

You fellas have room for one more in the window leak club?

 

Before purchasing my 19 Elevation, I did my homework and read all about the leaks and 8 speed transmission problems. Thought I picked out a gem, transmission has been baby smooth and no signs of any leakage until I hit 1500km's.

 

After 1 month of ownership and a couple heavy days of rain, I saw water running down the drivers side rear corner window. 

 

Long story short, the truck was in the shop on May 26. I was told the window was on backorder, but there was 1 window available at a different dealership that they would try to get for me, otherwise it was unknown how long sourcing a window would take. Took the truck home and was told to hang tight for a phone call.

 

Took the truck home, had multiple conversations with GM customer service. I was then notified by the dealer that they were able to pry the window away from another dealer and was booked on June 9 for the install. The window was installed by a 3rd party glass company. Meanwhile, as I was waiting for the window, it rained 6 out of the 14 days that I had my truck out of the shop. Luckily, the headliner didn't see any water damage and I kept a towel along the backseat to soak up any of the leakage. As well, no odor or rust on the seat bolts. 

 

As well, I was told they also had to source a windshield and keep one handy just in case they break the stock one as they might have to remove the headliner and as we all know, it can only be removed by taking the windshield out. However, since there was no damage to the headliner, they would assess to see if there was any damage once they open her up.

 

The truck was kept overnight on June 9th and I was called early in the morning June 10th to let me know that the truck was done. Before picking up the truck I asked them to do a leak test with a hose. It passed the test. I have to say, I am beyond surprised at the quality job they did. It looked exactly like it did when I dropped it off. No scratches anywhere, no sealant exposed anywhere. Leather seats unharmed.

 

On the way home, I took her through a high pressure touch less car wash. Not a drop...fingers crossed this is permanent.

 

2019 Elevation, build date June, 2019.

3 piece window with slider.

Original glass, FUYAO 43R0115130 E2 
After glass, FUYAO 43R000072 E4

 

Headliner did not need to be removed. No damage to headliner, looks perfect.

 

If anyone is in central Alberta and is in need of a replacement, message me and I'll give you the dealership name and contacts.

So my truck is back at the dealer, as my state (South Carolina) requires I give GM one final repair attempt before I can claim the truck as a lemon. A GM engineer was on-site for the inspection, and low and behold they found a crack in my replacement window, same place it cracked on the original window... My new window should be installed early next week, and I was told it has been improved and reengineered... Sounds like dealership talk for it's the same damn flawed design...

 

Has anyone heard of there being a new design rear window out there? My first replacement was from August 2019.

 

For those that may not know my entire store. My original window was resealed per the TSB, then the window was replaced entirely, then the replacement window was resealed, and now I'm looking at another new rear window.

 

On the bright side, maybe the 2021's will be out by the time I finally get to formally claim my truck is a leaky lemon.

Wow, 143 pages of leaky windows ? .... I had the pass-through on my 2015 and have it again on my 2020. I rarely open it unless the grandson is in the back seat. So far with the new one I've driven 30 miles in an extreme down pour and hit it with a high pressure hose and covered the entire window frame and the seem where the spoiler meets the roof. No leaks whatsoever. My build date = 02/20. Hoping I got the updated part and wont ever have a problem. I do have two questions for the group:

 

1. Does opening and closing the window cause wear that eventually will cause the leakage?

 

2. Are there instances where there were no leaks when the truck was brand new, but start leaking months down the road?

 

I certainly will be keeping a keen eye on this for sure!

      Some Assembly is Required

      By Grumpy Bear · Posted

      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.

      Software Update

      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.
