2023 3500 Sierra Roof Leaks

[Hawkens999]

Wanted to check in here and see if anyone else has had the same issue with their Sierra HD.  I have a 23 3500 HD Denali  that just hit 51k miles and just started to see water leaking into the upper rear cabs, just above the window and below the 3rd brake light.  What is going on??  I have had so many vehicles in my life and I cannot say that I have ever had one that leaked water into the cab?  Years ago, delearships used to say that it takes 50K miles to properly break in a vehicle.  Now they only warranty work for 3 years or 36k miles.  I called my local dealer here in Utah and got the whole story about this being a common issue.  I saw a older recall notice for 20 - 21 models with the same rear wing design but not my model.  The older service sheets state that GM will pay for 1.5 hours labor on these recalls and Im being told that they will need 8 hours to repair the same non-recalled design.  What is going on?  Anyone else have any other thoughts on how to get this repaired?
