I am in Canada so the recall was done on my 2015 Sierra in early 2020 however this morning on my way to work (out side temps of 0c and no high winds, snow or rain) my driver side rear window shattered while sitting at a red light with the rear defrost on, didn't smell anything or notice any smoke just heard what sounded like a gun shot and then notice the window was shattered. Currently arguing with GM Canada that it is from the same issue and that their "fix" didn't work. Anyone else have the recall done or at least the service done and still have the window shatter?
