Lol it’s kinda funny but I have owned 3 Duramax a 2012 ltz (had Rust issues) then I trates and got a 2017 Denali which had another paint issue paint on the bed was coming off, then I traded to the 2018 that I currently have a another Duramax Denali and the pint it’s bubbling on the roof by the sunroof, anybody else here having this type of issues ?
how often do you wax it and hoe often does it sit outside dirty. but for the most part you will be guarenteed to see problems from the LMM generation going into the LML generation as GM was upside down hence why the lmm was so incredibly cheapely made.
