I had purchased mine in March and only been driving to work (4.5 miles each way) so I didn't ever see, November 11th we went to the In-laws and it was raining, My 10 year old says I'm getting wet, It was scheduled for its first oil change on the 26th, said they would need to keep it for about a week, I told them I would need a loaner can't be without wheels for a week, so I had to wait almost 1 month, they call, I drop mine off and pick up a 2019 Z71, last night we are coming back again from my in-laws, we stop to get gas and my 4 year old daughter Mon! this truck leaks in the same place as daddy's truck!

Lol, wow. This is really going to turn into a huge issue for GM. 
 

Got mine in March 2019, too. It was a Feb 2019 build. Started leaking after 8 months, 7000 miles... which seems like a lot of people’s stories right now. With winter and spring upon us, the dealerships are going to start seeing a LOT more of these.

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.

With as big as this thread is, are there any trucks out there with significant time and mileage that do NOT leak? If so, I wonder what the difference could be between those that leak and those that don’t.

I used to think this was an issue isolated to specific build dates. But in the past few weeks a lot of us 2019 builds and even some 2020 builds are saying they are leaking. So methinks this issue is much worse than people think. 
 

I will safely speculate to say that nearly every T1 will have a leak at some point.

This is crazy, because lastnight it wasn't even raining hard when my daughter noticed the loaner was leaking too. Monday I'm calling Chevrolet and asking them to replace the rear window, I was reading that's the only real fix.

Mine was a Feb 2019 build and it started leaking around 7000 miles.

Good luck. It’s not really the only real fix, as there can still be some seals on the spoiler that leak. But it’s the next step if they already resealed your window.

Been raining the last two days on and off and no re-leaks yet. But man, I'm checking almost every day. This isn't mentally healthy. Didn't start leaking until 12k miles. Nov '18 build, bought in March '19. No leaks until December '19. I would bet and agree with @econometrics that this issue affects all Silverados. There are only two types of Silverados, ones that have leaked and ones that will.

I probably had less then a 1000 miles on my 2019 when I first smelled a bad odor. I thought for sure the carpet had gotten wet but I could find no evidence. This happened several times over the next couple of months until I finally discovered wet carpet just inside the drivers side passenger door. I started researching and found this forum and that;s when I realized it was coming from the rear window. My window is leaking on left and right side. There was water in the sliding window track and the plastic trim around the window is cracked. Going to the dealership a week from Tuesday. i wanted to get the holidays behind us so maybe the technicians will have a little focus. I'm going to stress a new window be installed because of the large crack in the plastic trim around the sliding glass. No amount of new sealant is going to fix that issue. So we shall see what happens.

I don't think the solid rear window is included in the leaking.  I posted in another forum. It seems like it's not IF it's going to leak but, WHEN.

I was dreading it before but now I’m really worried about it because I just had my interior redone with katzkins leather the last thing I was is some greasy tech getting hand prints all over the inside of my truck. Not to mention the horrible sealant and scratch job that comes along with the exterior part of the repair

Right, I think the solid rear windows are fairing better. I guess I haven’t heard if anyone here with a leak has the solid window? I assume we all have the sliding rear. 
 

But, seeing how the spoiler is attached to the cab, and the poor engineering for water flow there, I could see how the solid rear windows could leak at some point, too. 
 

Main issue here seems to be that the sealant doesn’t keep the seal after some time goes by with the truck flexing and freezing / cooling, etc. Both sealant on the sliding window frame, but also around the spoiler bolt locations.

I think part of the issue is the slider window has a piece of plastic for the window slider in-between the glass and gasket. The solid window is just glass and gasket but I would have to double check on my loaner. It's just a bad design all around. All to add a stupid spoiler that doesn't even look that good.

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.
