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.

Do you do it yet? Washed the truck this morning and checked. No leak. 

So, it's been over a month since you installed this and no leaks? 

 

Must be leaking from the spoiler bolts and running to the top of the window from the inside.   Goin to order this and try it myself!! 

 

FYI- I ran a similar rubber seal between the window and window frame on the outside, across the entire left side of the window and it didn't stop the leak....so I think it is coming from the spoiler bolt!  

 

Washed my truck yesterday and it's still dripping inside on the driver's side, at the plastic piece on the top of the window, still just a few drips but dripping nonetheless! 

 

This picture was a few months ago, but that is the spot, right on the corner of it!

 Yep did it a couple months ago but the truck is parked in the garage, my wife and I are both working from home and it hasn’t rained much. Can’t guarantee it, but so far so good. Worst case you’re out $15.....

Update on the Trim Lok. Had a few days of rain here and no sign of leakage. I highly suggest you give it a shot. $15 and about 15 mins worth of time.

I ordered this exact Amazon Trim-Lok product, but I cannot get it to fit into the upper gap of the spoiler.  I even tried lubricating it with some silicone spray.  How did you guys do it?

I just put it in yesterday...I'll keep you posted.  I plan on water testing it instead of waiting for rain.  Full disclosure, I don't have a leak since they replaced my rear window.  This is more preventative.

I used interior plastic trim tools to get the cord between the spoiler and the cab.  Gap was that tight on my truck.

Anyone that's had the window leak fixed under warranty via a dealer, have you noticed an interior rattle after the work was done? Apologies if this has been brought up. Tried searching the posts but no luck.

Mine was repaired last week at a reputable dealer where I purchased the truck. Noticed this morning on my early coffee run with no music, etc a distinctive rattling on any little bump I hit that def wasn't there prior. I'm hoping it's my son's car seat and/or something he left in it, [emoji1787]

2019 LTZ 4x4, 6.2. For reference.

I used the handle end of a plastic frozen yogurt spoon to work it into the gap.

Might be the headrests on the backseat.  Do a search for it on the forum.

Same here, small drip, just about not noticeable but found it after a serious hard rain.

Headrest rattle like others said before, easy fix to just spread the headrest legs out

OR

Rear cab vent(s).  Check to see if they didn't knock those out.  I got mine back after the window and the driver side cab vent was loose. 

OR

Could possibly be spoiler attach bolts.  I personally feel that this might be a big part of the leaking problem, as my window wasn't cracked...but they insisted on replacing it anyway.

When they did, the leak was worse, and in a different area because they didn't seal the spoiler attach points.  What a mess.  Still have a noise in the cab during extreme temp changes...and I believe it is due to the spoiler not torqued correctly.  Which led to the leak.  Just my theory.  I am probably way off the mark.

Yes I had the rattle. Pulling the headrests and “widening” the bars did the trick. Hopefully I can just enjoy my truck now. No leaks since rear window replaced.

Wow that is considerably worse than mine. They discovered a foot of sealant was not applied at the factory. They ordered me a new window regardless.

Mine is getting worse too.  Doesn't even take much moisture anymore.... just a light rain and the interior is wet. 

 

They discovered a foot of sealant was not applied?  Is that new info?  Source?

      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...

      By fm2176 · Posted

      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.
