So it seems now that the real source of the leak are these spoiler bolts that are not properly sealed with the sealant? So water passes through them and soakes the headliners?
 

That is correct.  And the TSB does not really address the spoiler bolts all that well.

Well that seems to be a much simpler solution than the original TSB. Would of saved alot of owners some headaches and trouble if thats the case?

 

Did GM redesign the bolts or do they instruct the dealers to apply sealant every time before the bolts are reinstalled?

If they do it obviously is not right since my truck has been back 4 times for it leaking lol

I’d say that the spoiler is ONE source of the leaks. The other is clearly the sliding window frame cracking.

Had my 19' Sierra repaired a while back. Was leaking on both sides, passenger side was worse. Dealership I use did a great job. Have to look really hard to see the sealer that was put on the back glass. The tech that works there does all of my warranty work on all my vehicles. He always does excellent work. Have never had to return any for the same issue twice. Has not leaked since repair was done. I did ask about the spoiler and if he thought that it could also be leaking from there. He said that he has not had one yet to be leaking from the spoiler, all he has seen were the back glass leaking. He has done so many he can't count.

Just got my 2019 sierra back from getting the TSB for the spoiler bolts done and low and behold it still leaks. I guess they didn't even check it before telling me it was fixed. It will be going back Monday morning. Looks like this is going to be a long aggravating road. I knew I should have just bought another Honda!!!!!!!!!!!!!!!!!!!!!!

Does anyone have this supposed TSB for the spoiler bolts? I have the one for the window, but didn’t know one existed for bolts on our trucks.

Never heard of the spoiler leak issue. As I stated in my earlier post, the tech I use said he has not had one in with the spoiler leaking, it has always been the rear glass leaking, caused by cracks in the plastic frame that is sandwiched between the body and the glass. Not saying they don't leak, but the tech that did mine said none of the spoilers were the issue, and he has done a lot of these trucks.

So my rear window is cracked but i sealed it up and the spoiler bolts, it does not leak anymore. my dealer said he would replace the window he has seen where the plastic frame is cracked in 3 places. Is it just going to crack again if i get it replaced? Or should i just go ahead and do it. Id hate to see my interior get torn up just for the window frame to crack again. Thanks in advanced fellas and hope yall get yours fixed.

Nobody can answer until GM comes clean on why they are cracking.

So you're saying its pretty much pointless, it'll just crack again?

I am saying that only GM knows and won't say.

    • I wonder how much carbon is on all those high mileage valves?
    • When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007    
    • I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆
    • 2020 2500 HD...I had some trouble getting the key into the ignition switch but went in fine after applying some extra effort. Since then, the door chimes when open when the key is out of the ignition. Also, when I lock the doors with the switch on the arm rest, the driver door locks but then unlocks. (I can lock everything fine with the fob) The message on the little screen displays the "Engine Hours"...kinda weird.   I'm guessing something happened to the ignition switch and it thinks the key is still in there. I unplugged the batteries for 20 minutes, no change. There are a number of videos on YouTube but nothing I can find that address this specific issue. Ideas appreciated, thank you.
