I had a Sierra a little while back and was having issues left and right. Contacted California Lemon law Center to see if something could be done about it; they were able to get all my payments back and even some on top. Would highly recommend any of you who are experiencing issues with your cars to reach out and see if you have a case.

Here’s their website: https://californialemonlawcenter.com/

I see you're new here and posting this same BS everywhere. Not a good thing to do IMO and not everyone lives in CA (thank goodness).

Just had my whole back window replaced under warranty because it was leaking on passengers side.

PSA, I highly recommend anyone with the rear window leak to inspect your bose amp for any liquid contact.

I had to get my Bose Amp replaced on my 2020 GMC Sierra 1500 AT4 as it was causing some driver speaker not working and creating a thud noise. I had to shell out the repair as I had too many kms (~126,000 kms). I requested to keep the original Bose Amp unit, I found corrosion on the unit and the unit its NOT water tight. The bose amp unit is right behind the rear seat where the water would travel to.

I was fortunate enough to have a contact at the dealership that got a staff deal out of the repair, but I still paid about $900 CAD for diag and R&R. The dealership did escalate the case but GM rep was only willing to shell out 25% of the "warranty" rate, which would be more than what I have paid for in the first place.

Anyone having issues with '23 or '24 year trucks? Wondering if any improvements have been made.

Got tired of the crap repairs and had the window replaced with the solid glass. Hope this one will be trouble free for the life of the truck. I know I probably won't get another GM truck until the back window design is changed.

Welp, 2024 Denali ultimate. 1700 miles and leaky window. Did the Leevon method in the garage today. Maybe GM will engineer this problem out on the next platform, but I’ll believe it when I see it.

Maybe in another decade or so........

That sucks. After having several leaky windows and replaced the last one with a solid window, there was still a slight drip. No where near the streams on each side from the cracked slider frame though. I now believe the cab structure at the window is weak as well, contributing to the window frame failures. I'm done with these trucks and their crap designs until they change it. Going on 6 years and it's still an issue... Guess it's like the AFM/DFM lifter failures that they ignore, too.
