I have been servicing my car faithfully. I garage my car. I only drive 3 miles to work. New Jersey weather has not been that bad over the past 6 years. My local mechanic has said it is the worst rust and corrosion that he has seen to the subframe in over 20 years in business. When I brought it to Chrylser, their "certified" mechanic said it was "normal" weather corrosion. When I called Chrysler headquarters they said I should have brought it to a car wash every 2 weeks! If their mechanic said it is "normal" corrosion, then they will not reconsider fixing it.
