I bought a 2018 Silverado and in a little over 2 years the frame was just about rusted through. It was after they removed the wash bath to save money and sealed the etching chemicals in under the wax undercoating causing it to rot from the inside out. One day chunks of undercoating and rusted metal fell on the garage floor alerting me to the issue. Found out it was a common issue with a TSB. Chevy agreed to do the TSB for it but after having it for 3 months said it was too bad to fix as the whole truck need to be disassembled for the TSB to be done and they couldn't even find a shop that would touch it. So they put 3/8 of an inch of Ziebart on the whole bottom and said they would monitor it a couple years because it would eventually rust out anyway then returned it. I asked forca replacement and GM said no because it would eventually rust out anyway. Luckily the dealership bought it back right before I hired a lawyer. GM is terrible if you have a serious problem. It was a pretty, comfortable, and powerful truck with the Corvette engine but lifters were getting noisy at under 10k miles also. Had the high desert package with ram boxes that were nice but expensive. Never ever had a Ford rust like that so went back to Ford that may have been another mistake with Pandemic quality in 2022.
