Well... This window didn't even last through the frigid cold California winter this time. Window number 3 Already leaking in this last rain storm!

Bummer. Time to get a lawyer and get out of that thing. Just unreal.

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.

2019 GMC Sierra and am on my third window. In the beginning they did the spoiler TSB and resealed the window. Still leaked so they tore it apart again and found the window frame had cracked above the driver side rear seat. They replaced the back glass and this fixed the issue. It has happened twice since then with the frame cracking in the same spot. The last time it was in the shop the window hack they used scratched up a little over $500 worth of plastics in the back seat that they had to replace.

This is disappointing to hear.  Waiting on my new rear glass to arrive.  I guess they should order 2 more since it's going to crack again in the future. 

 

In the meantime, it rained yesterday and now I have another 18 in. wet spot in the headliner. 

 

I'm really to the point of having GM take the truck back under lemon law and go get something else.

2020 Silverado LTZ Crew Cab with 18,000 miles and I joined the window leak club. :(   Thankfully my husband follows many Chevy sites and has been watching for this , so we caught it right away.

Dealer stated that GM has a notice out and they have to silicone it first, so currently its at the dealership where they hire a window company to come and fix.  It sounds like they remove the 3rd brake light piece that runs along the top of the entire back window, they will silicone and re-position it, then it has to sit in a heated garage for like 24 hours and I should have it back in a day or two.  If it leaks again, then they have the glass company replace the window.  My question to all of you who that have dealt with this,  after you had it silicone' d, did you have any other issues with the window leaking?

I had mine done over a year ago (silicone) by my dealership and despite the temperature extremes we get here, plus pressure washing, torrential and steady rain i have not had an issue with it since.

I almost feeling like calling gm or your dealers service department and bitching them out for you, that is disgraceful and no excuse for it imo!

 

If GM can't fix your truck they owe you a new one imo! Maybe ask them to give you the non slider back window, the sliders are the problem in these trucks imo!

As of this morning, I've secured attorney representation and notified GM of our intent to pursue a refund.

 

I'll let y'all know how it goes.

Good luck, i think you have a solid claim here if this is the result after 4 fix attempts, gm shouldn't be allowed a 5th!

That is atrocious! And after 4 "repair" attempts? Good heavens. So sorry, BamaBen. 😕

Not claiming to be an expert but fairly sure that’s caused by the yellow retainer gasket on the spoiler.   Bad gasket.   Can be easily replaced.  
 

Unacceptable that this is happening to you.  Looks terrible.

This is the 4th time they fixed it, and last time the over torqued his spoiler bolts. It’s back a page or two, but he explained it all.

At least that what they told me...  funny how the maintenance records on my.gm.com are not filled in for the last 2 service visits.   

 

The count currently is 3 fixes of the spoiler gaskets and 1 reseal of the rear window.  I'm not giving them the chance to repair it again.  Lawyers are on it.

I just had mine done on my GMC Sierra (2019), they did the silicone, very poor job, they used a white silicone that dried real hard and instead of level with the top of the window they went above it and it looked bad. Regardless, it still leaked so now they have ordered a replacement window for a glass company to install, fingers crossed this will be one and done!! Good luck!!

Unless the sheet metal has been damage from the over torquing.  Every bolt and nut can be replaced on the spoiler, without having to buy a new spoiler assembly.  They all just slide/snap in place on the spoiler side.

 

Of course, this whole thing shouldn't have happened.

      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

      By superdave160 · Posted

      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.
