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.

Getting mine back today from the dealer as well. New window installed yesterday. They said there was also a cracked grommet (some hard plastic piece) under the rear spoiler that they replaced as well, as that could have also been a cause for the leak. So, I think there is something to be said about the rear spoiler design having issues with letting water in the cab (in some instances - not all).

 

I look forward to daily ShamrockShooter all ok updates! :)

My rear window was ordered on Dec 30, talked to my service guy today and he was doing some research on it, looks like may be next week it will be here. I asked him what he thought the hold up was and said he did not know. The last time I asked him that, he said it was because of the holidays. I just laughed and told him, maybe GM is having to replace a bunch of windows, he had no response to that. Funny, you would think they would admit there is a issue.

My truck is scheduled for delivery in the next few days.  After reading through this leak issue thread (and being very concerned) I have a couple of questions:

 

Is every truck having leaking issues?

Are leaks occurring on trucks, regardless of build location?

As Centrebaseball says, build location does not matter. Is every truck leaking? At this moment, I'd say anyone receiving a truck with a slider should inspect the inside very well, especially those sitting on the lots for awhile. Mine sat for a month and no indication of leaks until a couple of months later. Also water down the backside and see what happens.

Knowing now, what I could have looked for would have kept me from buying a truck that had been sitting on the lot leaking. Lift the back seats and check for any corrosion on any of the metal parts. Surface rust on the black, back seat brackets. Also rust on your jack.  The first thing I noticed was after I had the truck home for a couple of days. I was looking at the jack assembly to familiarize myself with it and noticed rust on it. I immediately thought has this truck been in a flood. Looking back, I am sure the dealer knew my truck was leaking, it had been sitting on the lot for close to a year. I bet it was stored indoors after they discovered it. It had a very strong new car smell when the salesman drove it up to me to test drive, but that odor went away within a few days, like they had sprayed something in it. just my thoughts. Good luck!

Well today came and went with no call from my GM Executive customer service rep from Michigan. I’m going to call her tomorrow and see if she’s alright since she didn’t call today and let my dealership know. I’m fed up at this point and I also noticed rust on the hardware on the underside of my flip up rear seat.

HI @JohnCasey do you have a picture of the rust that is on the seat hardware? I would like to compare it to what I have going on since the dealer keeps telling me that the corrosion is not a problem. Thank you!

@PtownVdub, I posted several pictures a few days ago of the underside of my rear seats. Easy to tell. Flip the seats up and take a look.

I was always under the impression that painted metal parts wouldn’t rust as easily unless there are chips or exposed metal to water.  Hence, there is always talk about how GM should have painted frames instead of the wax coating to better protect it from corrosion.  I get paint isn’t going to be a permanent corrosion inhibitor but that rust seems to be a bit more rust than I would expect for painted parts on a new truck.

      287,500 Mile Service   8/13/2026   Reset Fuel Trims   Since the work done in the previous post there was a good improvement in response in all areas except right after a fill up where the LTFT would go -20%+ for about four miles while the STFT was near neutral. Before the work they both went very negative for a few miles after a fill up but act normal thereafter.    We did a systems check of the vapor recovery system for functionality and ability to hold a vacuum. That checked out fine. But this doesn't mean the charcoal canister is dead in the water. Testing that is next up. For now the reset of the fuel trims.    I intentionally shorted the fill exactly two gallons to eliminate any chance of filling the canister. On start up the trims were behaving normally until I got up and rolling where the LTFT went -10 / -11%% but the short was + 2 to 0%. Within a mile the the STFT offset the LTFT and by 2 miles they were neutral. HUGE improvement but still not hunky-dory.    I'll watch them for a few days. Perhaps another tank where I will fill completely to 'first click' and compare. Meanwhile on the hunt for a new canister and I'll toss another purge value at it for good measure. Pending the outcome of the canister test that is. Progress of any kind is welcome.    Fuel economy improvement with bringing hole #3 back to the living was a noticeable bump to the positive. Even on the few miles I drove after the refill I already see another bump up by the trims reset.     She's purring like a kitten with a warm bowl of milk.    BTW, adding 50 rpm to the idle took the majority of the negative timing out on cold start up and leaned the cold idle. No longer burbles in the cat. What a dumb way to heat a cat.

      Yeah, shame I can’t really get that filter easily anymore. Running a PureOne. Your fave!    TAN would be neat to see. Confirmation I ran it too long probably. 🤣

      Roll up bed cover experiences

      By superdave160 · Posted

      My son and I both bought new trucks in 2017. Both of us immediately put Truck Covers USA American Roll Covers on our trucks. My son still has his truck and it never sees the inside of a garage. We live in Alabama, so not much snow. My truck was my daily driver and was in the garage when I wasn't driving it or at work. No issues with either cover even after almost 9 years. About a year ago I sold my truck to my brother and bought a 2025 Silverado 2500. The second thing that I put on that truck was a new Truck Covers USA cover. They are very well made and have a very positive locking system. I looked at a Retrax and my concern was the way that the cover locked to the rail. BTW, the first thing I put on the new truck was step bars. Those new trucks are high!

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      The Allison 10 speed torque converter doesn't "lock up" like the previous transmissions. It has 4 operational modes; open, slip, transition from open to slip; transition from slip to open. I have an Edge CTS3 monitor and I monitor transmission torque converter slip. Step on the gas and you get a little slip. Take your foot off the gas and you get a little negative slip. I have not found a way to display the torque converter mode beyond that. My Edge CTS3 also displays something that our trucks should already display, the current gear. I also monitor throttle body position and engine load. If I see the engine load getting too high, I'll manually drop a gear.

      Nice result. Your filter is working well  I'd have like to have seen the acid number for this sample. Curious type that I am.
