I can't really disagree with anything you wrote, in fact I whole-heartedly agree with most, but I also think it is unfortunate and unreasonable that Chrysler wouldn't replace as opposed to repair those items on a car with fewer than 500 miles. The corroded connector was cleaned, no doubt, but I have to imagine that its original integrity was damaged in the corrosion process. I would want to have a brand new connection myself, not, in effect, a junk-yard equivalent. I have purchased many used parts and will probably continue to do so, but when I pay for new, that is what I expect.That is a classic case of fault->diagnosis->repair. I think it's unfortunate and unreasonable that he wouldn't take his car back.
