Undercarriage on 2016 canyon

[Jesse Butler 0]

Hey y’all so my mom just picked up a sweet 2016 GMC Canyon with 55k miles everything seems fine rides like a dream but finally got to crawl underneath and was a little shocked at what I saw but I do live in CT so the harsh road conditions Ofcourse eat away at cars so is this kind of surface rust common for something 4 years old or should I be more concerned about this being a big issue before the truck is even paid off. Seems to be mostly on the welds but def more than I was expecting..We have 30 days with the truck for 100% money back. Thanks for any feedback, I have more pictures but can only upload 2 on here.

Welcome Jesse...I too come from a harsh climate here in Canada and can tell that I've seen my share of rusty underbody frames. I would think your moms ride being only 4 yrs old is mainly surface rust. I bought a 2012 Sierra shy of 4 months ago and first thing I did was lift that sucker onto a hoist and air-blasted all loose rust. Krown sprayed black on the outer frame and visible exterior areas and Krown oil sprayed everything else.

Not sure if this helps to convince mom.
