Rear window leak

JAP90 · August 14, 2020

Mine has been in the shop for 11 days for the first seal repair. They keep telling me they're waiting on the new spoiler bolts (apparently upgraded). I'm getting rid of it as soon as I get it back. This has been going on for 2 years and they can't redesign a better rear window frame? Maybe the supplier knows their window isn't the root cause? Based on some other things I've read about the new bodies, I'm not certain they don't have a structural issue but I don't know that.

Can anyone confirm if the rear window and spoiler issue is only isolated to the 1500 class or have there been issues on the HDs too? Thanks for everyone’s help.

Anyway you can find out what the new spoiler bolts part number is? A few dealers in my area have no idea of there being new bolts for it.

yeah, dealers in my area said they don't know about new spoiler bolts, they are just adding caulk/sealant or replacing the window and still adding the caulk/sealant to the new windows.

Is this only occurring in slider windows? If so, I'm thinking about having a fixed window installed and being done with it.

So this is interesting... I was just cleaning up some "residue and dust" left on the spoiler and window. I noticed what looked like a used spoiler bolt gasket in the bed. I have a tonneau cover. The item looks to be a rubber washer about the size of a nickel maybe. I called up the service writer and asked if they replaced the spoiler bolts or washers/gaskets since I found a used one in the bed yet there was nothing on my work order about these parts. He said he'd have to ask the tech and call me back. He called back and said that after talking to the tech, they always replace the gaskets when they pull the spoiler but they don't note them on the customer tickets.

Individuals operating these vehicles with water intrusion issues would be wise to provide a source of constant freah air ventilation while driving. With the discovery of "drug resistant molds" it's not even worth taking a chance. By the time one experiences symptoms it's already too late.

Down here in Florida mold is everywhere due to how humid it is. Doesn't require rain at all.

All I know is the dealer told me the spoiler bolts are one-time use and they are on backorder. After waiting two weeks and wanting to just take it somewhere else, I called another dealer Shop Foreman in the area who fixed the leaf spring clunking (and who I should have used for this), and he checked and said they aren't lying to me, the bolts are on backorder. Anyone in TX want a good deal on a 2020 AT4, let me know!

I am in NC. Took my 2019 silverado in for rear window leak on Tuesday of last week. They resealed and called to tell me they needed to replace spoiler bolts. They ordered them and had them sent overnight delivery. Installed Wed and I was able to pick truck up Wed night. I am hoping this solves the problem.

Bought my new 2020 AT4 last month (July) and have given it a few washes with my pressure washer and really soaked the rear sliding window, perimeter and spoiler to see if I could detect any leak early on in the warranty period...no leaks whatsoever...feeling good...I wonder if they fixed the issue?

Nope. It just isn’t your time haha I have a 2019 with 3600 miles. No leaks yet but I know they’re coming...

Yeah, they made a mess of mine fixing the leak. You have to drop the headliner to pull the cab spoiler...so just about everything inside gets man-handled. Left a bunch of fingerprints all over the headliner, and a few broken trim pieces. I can’t ****** anymore though, everything was made right and it’s been a year with no leaky so I’m happy.

What did they do to your truck to stop the leak?

My 19 RST with slider rear window went in today. Service advisor told me they are fixing it per the TSB by using the caulking method.

The caulking, believe it or not worked on the first try and is still working. If done right, the concept works and it may be better than a new window (that will also eventually crack). The sealer is flexible and shouldn’t ever fail. If done cleanly, you won’t see it either.

Problem is usually the damage they do in the process. Leaving sloppy caulk residue on the paint, messing up the headliner or trim, scratching the truck, etc. Seen a lot of it here.

Since this problem has persisted for like 2 years now, I would think most dealers have done a handful of them and have the process down. But just make sure to look everything over really well. Some of the things they screwed up on mine were not immediately apparent. Good luck.
