My 5/19 build date TrailBoss rear window leak developed over the weekend.  Wonder why it started now after 5 months and 7000 miles? Passenger side rear seat water drops all over it and back corner headliner was soaked.  
 

Anyone dealt with this issue in the Dallas/Fort Worth area? 

Sorry you are dealing with that. Sounds exactly like my 12/2018 build date. I think the switch in 10/2018 is a load of junk, there are more later builds coming out of the woodwork that have leaks. Mines at the shop right now with the headliner ripped off and the sealant fix going on. Has been three weeks now without my brand new truck waiting on parts. Hope it gets resolved quickly .

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 cannot believe I am about to type this.

 

I have joined the club.

 

2019 Silverado Crew Cab, Short Bed, 4x4, 5.3

Build Date: 3/19

Bought New 9/21/19

 

So I've read this forum before and just sat back and felt bad for all you guys. I of course went right out and took a hose to my windows for a solid 30 minutes. Never a drop. However for some reason I never looked up at the liner. Only the window for water spots.

Welp, washing it today and testing it again. This time I looked up. To the dealer I go.

Something else to add - I think my repair has actually been done. No water came in today either. This is a dry stain. I think they fixed it and that's why it sat from 3/19 until I bought it in September.

So further inspection on the back channel where they put the sealant - it doesn't look like it's been applied to mine. No mess or overspread. I don't know what to think. I've held a hose on this thing for nearly an hour and can't get it to leak.

 

Do you think the dealer will tell me if they repaired it before it was sold?

Same story here. 7000 miles and a Feb 2019 build. Just started leaking on the top of the rear driver's side seat. My headliner hasn't been wet, though. 

 

Classic Chevrolet is my closest dealer, and I'm sure they have dealt with a few of these since they're the highest volume Chevy dealer in the US.

Sucks man. I’m so sorry. I’ve spent 3 hours now with a hose on mine. I’m convinced the dealer fixed it pre-sale and then didn’t replace the headliner hoping they could get away with it (which they did.) I didn’t catch it that night when I bought the truck.

That’s pretty wild. I would raise that with them and get you a new head liner. If it’s not leaking, they pulled a fast one here.

That stain looks like it should clean up if the dealer has a competent detailer on staff. Mine looked about as bad but was cleaned up fine (after the second attempt). I was cautious to push for a new headliner because that means the windshield has to come out. And you can guess all of the things they can screw up in that process....


To me, it seems really unlikely that someone at the dealer would have noticed the leak and then taken the initiative to fix it. And then not clean the headliner. Really, even if an employee happened to move the thing around the lot on a rainy day, who’s going to look in the back seat at all, let alone look up at the headliner and investigate. Not to mention, when it’s wet, you almost have to shine a light on it to see the water spot. It’s so dark back there with the tinted windows and dark interior colors. Just my take...

Well that makes me feel better. I would hope they wouldn't do something that shady. But who knows.

 

That sucks even more though if you are right - That means mine is doing the slow leak in rain only. I saw a couple people on this thread that said theirs would only leak when it rained, not when a hose was applied.

Given the opportunity I’m sure they would pull some pretty shady stuff, but frankly I just don’t give them enough credit to even find the problem. Plenty of people have “the leak” for who knows how long before finally spotting it. If it’s slow, and doesn’t drip onto the seat where someone would see it easier, it would be really really hard to spot until the water stain on the headliner dries. Likelihood of an employee at the dealer noticing this in passing...just not very high at all.
 

In my case it was true about the conditions that might trigger a leak. I had mine through high pressure washes at least 2x weekly, some hand washes and everything else, no trouble. The leak only surfaced after a steady, soaking rain overnight.

 

I mean, either way you have to take the thing in for the headliner, may as well have them inspect the window channel for the cracks. Maybe the window is fine and it’s just the 3rd brake light seal which would probably be the best possible outcome.

Guess I’ll have a good opportunity to see if my leak from the other morning was a fluke, or if my truck has finally succumbed to its T1 fate...

Has anyone had the leak not be the rear window? My dealer said they have seen 3rd breaklight/spoiler leak. Also called another dealer and they said something about a body seam that didn’t get epoxy from the factory?

Mine was the 3rd brake light/spoiler housing. They resealed it and it is going on 6 months and so far, knock on wood, no more leaks.

I'm praying mine will be the brake light. I'm taking it in tomorrow.

It’s been raining off and on for nearly the past 48 hours. My RST has been parked inclined on my driveway, with the bed lower than the hood. 


Here’s where my water leak is coming from:

Very minimal trickle. I left a paper towel at the top of the seat to absorb any water over night and it was damp this AM. So I’m glad it’s not a terrible leak. 
 

Going to try and get the truck in for a fix this week, but not sure if I’ll have time.

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
