This is my 2018 Toyota 4runner. It only has 3,000 miles on it and has not seen a Winter yet. I brought it to the dealership because I was shocked at the amount of rust and corrosion that has set in, within a matter of 3 months! They told me that this is normal. I really don't think that this is the norm. This is my 3rd 4runner and I purchased it with only 225 miles on it. Any feedback/suggestions would be really helpful. Thanks!
