Unfortunately not very exclusive.  Like death, we will all have it at some point.

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 was sarcasm

 

So what is the actual fix? Sealing? Window replacement?

 

I spoke to my local dealer and they mentioned sealing it and it would take a few days [emoji2373]

Curious how many of these leakers GM has had. 

The better question is how many are leaking that people don’t know about.

There is no actual fix. First attempt is to caulk it with Kent seam sealer. Best you can hope for is that they don’t make a huge mess in the process. Sometimes that “repair” lasts for awhile, sometimes not. My sealant job was good for a year. Just leaving it with the slight dribble it recently developed.


Usually takes a couple days to get done because there is a cure time before they can leak test and give you the truck back.

I still believe 100% of these will leak at some point. Especially the 2019s. Prove me wrong.

Every single truck with a sliding rear window either IS or WILL leak. I used to be less emphatic on this, but it's become very clear that I can say this with realistic assurance.

Yeah, @RyanbabZ71 I agree with OnTheReel. Let them do the reseal. Usually it does help... for a while. Mine held for a couple of months and now has a slow drip that I've learned to live with. I just keep a towel at the top of my seat between the window to absorb the leaks. My headliner is not being stained, thankfully, and my truck is not at all smelling of dampness.

 

You'll just be needlessly miserable (and without a truck a lot) if you want to try and keep pursuing it once it leaks after the reseal. This thread is full of examples.

We need a Bernie leak meme.

? ?  Bernie sitting at the GM dealer waiting for his truck's rear window to stop leaking.

LOL

Or maybe using his mitts to soak up the drips.......

It's interesting and frustrating that GM won't approve a solid replacement. 

I've had the initial repair done, and it's been fine since, but it's ridiculous that every time it rains, I feel compelled to go check it. 

 

I'm deciding between waiting for it to happen again, and trying to get them to cover it, or just go do it myself at a local guy's shop 

 

It's too bad that this is going on, I really love the truck otherwise. 

 

Thank you for the information on pricing and your experiences!

19, 20, 21. When will it end? What the hell kind of engineers do they have that can't solve this problem?

I’m leaning towards just having it replaced by a professional glass shop. I don’t want to deal with the dealer. They can only do what Gm lets them do. If I can do it for 5-600 dollars, it stings, but it’s worth it for a 50k truck. 
what boggles my mind is that GM just about forces to get the slider. Wouldn’t you think they’d stop pushing it by now? They gotta know it doesn’t work.

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.
