Yep, rust belt here too.. hate the salt!! I'd rather drive on snow and ice to tell the truth. Between the cost of buying, applying and the environmental impacts, salt only belongs in the ocean or on the table as far as I'm concerned. I refuse to use it on my property, wife doesn't like me not using it but, it just makes a mess and ruins stuff.Again, I have lived most of my life in Michigan, we use salt on our roads. I use salt on my walks after I shovel. Never had a car do that. I’ve seen plenty of rust, but never seen it devour a frame component.
Rusted subframes? Way of life in the rust belt I'm afraid, surprised you've never heard of it. I hear about it regularly TBH. Brand of vehicle has nothing to do with it either IMO. Chevy, Ford, Honda, Hyundai..it doesn't matter, they're all built to last 10 years or less. Planned obsolescence.. they don't want a car to last too long.
