Hey Guys. I’m back after the last replacement window lasted almost 1 yr before it’s leaking again. To recap my issues  bought on Halloween of 2019. 20 days later noticed huge stain on headliner and water on back seat headrest. Throes the caulking job 3 times before demanding a window and headliner replacement.  Took 80 some day to get the window and headliner in during which time I was put into a loaner Malibu(we called it the malirado). That lasted 5-6 months before it leaked again and they replaced the window within 4 days. It’s been almost 1 year and now window #3 is leaking and the dealership told me Friday I the phone that I’ve got a factory defect and I should sell the truck and get another. GM Executive customer service has been horrible to deal with. Never calling back and claiming to have spoken with dealership and the dealership doesn’t hear from them. I’m taking it in on Monday so we’ll see what kind of mess this one turns into.

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.

Sorry to hear all the trouble everyone is having.  I had a '16 that leaked from the XM radio antenna and then the high mount rear stop light.  I just upgraded to a '21.  Will be watching for the leak.

 

For those getting work done, are they cleaning up the headliner and interior to clear watermarks and make sure no mold?

Rode back out to the dealership to get my pistol I forgot in the truck and a wahoo fillet I left in the cooler after a weekend fishing trip. Found my truck sitting outside in the rain. I’ll ride back by today and see if they left it outside overnight or not.

So a little update. The truck has been up at the dealership about 7-8 times and the past few times I haven't even taken it home due to it still not being fixed and same for today went to pick it up while it was raining and had water coming in so had to leave it there again and take the same little buick suv home again. At this point they have replaced the spoiler 2-3 times the headliner has been replaced the window have been revealed countless times. Opened a claim with GM and they are basically useless. At this point I don't think it's fixable it's really disappointing

Picked up my truck today from getting the rear window replaced and the seam sealer applied to the new window. Dealer did a good job. I haven't noticed anything messed up. Now to see how long it lasts without leaking. I did however notice that this window is not tinted as dark as the original. Original was 18.5% and this one says 22%. Can't really visually see it. Was curious if anyone that had theirs replaced had the same thing? I wasn't aware they made them in different tint percentages.

I’m in the same boat so to speak. I received a call from GM Executive care and they are telling me that they have to replace the window again for a fourth time before they will entertain a buyback.  The lady I’m talking to is leaps ahead of the last three I’ve had. I told her that this was ridiculous and that I would just take it back and expect another truck next time. Three windows have failed and this one will too.  She touted a new redesign of the rear window but that’s the one that’s in it now. We’ll see how long it goes before I take it back for leaking window #4.

Got mine back from the dealership and there was visible excess caulking pushing out all around the glass and on the paint.  I was furious.  They kept the truck for an additional week+ and installed a new rear window.  In the process, they scratched the hell out of my paint beneath the rear window so it went to the body shop to be repainted.   The truck is back and doesn't leak, but the paint job was sub par enough to where I can notice the errors but the body shop cant.  Not happy, but as long as the truck isn't leaking I can deal with it.

That's the real problem with issues like this not being fixed, this has been a problem on three model year trucks now.  The real issue is we're seeing a lot of people getting sub-par repairs, paint damage etc.   Plus after a while there's only so much you can go back to the dealer and complain about.  It's like sending a meal back at a restaurant, you don't want to do it more than once, if you do you don't want to eat what they replace it with. 

 

My guess is it's simply cost cutting, GM hopes that slathering a $12 tube of sealant on it holds it till you are past 3/36, because after that, it's your $ to fix it, not theirs.   "Normal Operation" has become the new cop-out for GM.   GM is earning that least reliable vehicle "award" that Consumer Reports gave them last year, I'd imagine they'll be a repeat winner this year as well.

Got my truck back after window #3 top of window was not leaking as of now but water is getting in it some how because the carpet is soaking wet and all the metal and seat adjustments that are kinda painted to not painted at all are all rusty

It’s leaking behind the corner Trim pillars. With the latest window I had that’s where they moved the weak part to. I found it leaking on mine from The stained headliner and had water on the lower part of the window frame and top of the seat back.

They are now replacing the carpet in the truck and the window is still leaking it seems like they just do things backwards at GM. And I found the window leaking when it was raining the whole lower slider track had water in it with the slider closed. I will have to look for more when if I get the truck back this time

Well, add me to the list.  My truck is a 2020 Sierra SLT 6.2 crew cab with 23,000 miles (purchased in February, 2020).  I dropped if off at the dealership this morning for the first round of attempting to seal the back glass.  Fingers crossed for no scratched trim pieces.  My OCD won't be able to take it.

Anybody get there leaky sliding window replaced with a fixed window?

GM will not replace the slider with a solid window but you can do it on your own.

      Towing In Loose Gravel

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.
