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.

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.

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.

      New to Me 2010 SLE (Quirks, Issues)

      By davester · Posted

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
