Man you like tempting fate, outside of your warranty too no less.
I don't get the people here claiming not everyone has this problem, and your point to that is what?
It is a thread asking if the same problem will carry over to the 22 model year, my answer to that is yes. If the body structure remains the same and they have the ability to carry over the same window
part content wise, knowing gm, yes they will as it saves cost.
Far cheaper for GM to just have dealers dump silicone on your back windows and at worst have to replace the window with another one.
