So my truck is back at the dealer, as my state (South Carolina) requires I give GM one final repair attempt before I can claim the truck as a lemon. A GM engineer was on-site for the inspection, and low and behold they found a crack in my replacement window, same place it cracked on the original window... My new window should be installed early next week, and I was told it has been improved and reengineered... Sounds like dealership talk for it's the same damn flawed design... Has anyone heard of there being a new design rear window out there? My first replacement was from August 2019. For those that may not know my entire store. My original window was resealed per the TSB, then the window was replaced entirely, then the replacement window was resealed, and now I'm looking at another new rear window. On the bright side, maybe the 2021's will be out by the time I finally get to formally claim my truck is a leaky lemon. Sent from my SM-G988U using Tapatalk
