Ha, no. I'm in DFW. It's at Classic Chevrolet in Grapevine, TX. 
That's funny. The Chevy dealer up here advertises they are the largest volume dealer in the nation.

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.

Haha, they all probably have some *asterisk by the end of their claim of being #1. 
 

I know that Classic has over 3000 Chevy’s on the lot. It’s nuts. They move a lot of metal.

Well, that was quick. Dropped my truck off at 9:15am and had it back at 4:15pm. 
 

2 recalls, rear squeaky brake checked (they were unable to replicate ?), tires rotated and... sealant applied to top of rear window. 
 

They said they followed the TSB instructions for it and were not able to get it to leak after applying the new sealant (sounds... familiar). 
 

The tech did a pretty good job. Some smudgy hand marks on top of my spoiler on the roof, but they didn’t run the truck through the wash before I picked it up. 
 

Here’s a pic. It’s a consistent application of sealant across the whole top of the window.

So we shall see. There’s been a lot of AM condensation here lately, and my truck is parked on an incline, so I will know quickly if it’s leaking. ??

One of my dispatchers husband has an early 2019 that she drove today. I asked her if I could look on the back glass to see if it has leaked. She said sure look all you want it’s been dry so far. One quick glance with my flashlight and the streaks were obvious as was the broken window frame and the stained headliner. I hate it for them I guess I just had to share my misery.

Well they didn't follow the tsb as it says let it sit 24 hours before testing for anymore leaks..... Did you check you headliner, rear seats, and rear corner inside plastic trim for greasy finger prints and scratches?

I dropped mine off tonight. They are going to remove the spoiler tomorrow and see if it is the frame that is cracked or maybe just the urethane gasket on the window wasn't installed right.

The 8 speed in my 2020 lt loaner is smooth as silk. So much different than the clunky 8 speed that was in my 19 that was bought back. Guess it really is a luck of the draw with that 8 speed

Well better now than later. It's not your fault GM sold us a bag of lemons. You did right by them. Nobody I know or work with has dared to by a T1 Silverado after seeing what I went through. That is probably 10 k2 Silverado s in the parking lot that will all become Ford's or Toyotas.

My headliner and rear seats were not affected from my leak, so they just took off the spoiler and sealed above the window, thankfully. But, yeah, I was surprised to get a call just 9 hours later to come get it. Oh well.

Totally agree. I had a 2020 loaner with an A8 and was shocked at how smooth it was with just 1000 miles on it. Wonder what the difference is? New fluid in the torque converter? Mine still has the old, pre-March 2019 stuff.

No what I was getting at is to get the rear spoiler off, they need to pop the inside trim off and pull your headliner down to get to the bolts that hold the rear spoiler on. It's really hard for someone working in a shop to have clean hands all the time. As a result every time my headliner was pulled down there always ended up being greasy fingerprints.

I'm inclined to think its a flexing issue with the body too.  We've had a similar issue with a Jet Vac truck of ours with the frame flexing and ripping the radiator apart. We crossed braced the radiator with 1/4" steel and haven't had an issue with that one since.  The dealership is swearing they are testing it the day after they fix it but it.

I found the leak on mine Monday morning during a light rain, dropped it off at the dealer that same day, they called me today advising it’s done, rear window replaced as well as recalls done.  I was shocked they were able to get a new rear window in that quickly.   Hopefully this takes care of the leaking

Does anyone know who will call me now? I just told my senior advisor lady that I was not happy at all with the way they were handling the problems and that they are making trucks every day so there are parts available to GM and I wanted to talk to someone higher than her that could do something.  I also told her that NC lemon law is 20 days and they are well beyond that along with 4 times back to the dealership and they hit that this time.  I told her that somewhere in North Carolina was a truck like mine that they could swap out and make me whole. So she said her supervisor would call me within 24hrs.

Good luck.  You'll need counsel for them to entertain that.

I find that extremely hard to believe you have a new window.  Maybe they sealed it.

we can go that route if I have to.  NC is a loser pays state.  I did ask her about that and she told me that was a different department and they lawyers would have to talk to them. The senior advisor told me three days ago that she was going to check into my parts and see what the expected delivery time is.  Today she told me the same thing and I'm tired of being told she will find something out and call me two days later.  Why can't she just find out and pick up the phone and call at that time-(I actually asked her that and she told me she is very busy and there are other people having issues besides me so everything takes 48hrs to do).

      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.
