I don't really think at this point that anything is going to be done. Shy of a class action lawsuit, GM has your money and good luck getting them to stand behind what they have built.
For those of us that would want to sell our trucks to someone else, it would lessen the sale price since you have a truck with a clear defect. Try turning in a Chevrolet rental with paint defects and watch what happens to your final bill.
I'm not sure what a warranty is for when GM won't stand behind their product. I hope the dealers are telling clients that the truck they want to purchase has a defect acknowledged by GM on July 14, 2022 & literally zero has been done to address it. Very frustrating.
