I have a 2021, with only 31K miles and I have a leak. Date of purchase was April of 21 so I'm 4 month past the warranty date. This truck is still basically new and because it is four month past the warranty date they won't even look at it, but when I told them what the issue was they were well aware of the problem. Just said I had to go to a window shop. Com'on Chevy, you can do better then that.
