One problem related to coolant leaking has been reported for the 2000 Chrysler Concorde. The most recently reported issues are listed below.
I have several rather expensive failing items on my car including recurring issues: had to replace the r/p steering at 65,000 miles steering rack had excessive play at the 'neutral' or straight position; the molding around all doors has pulled away from the body of the car; rear door locks need to be replaced due to electrical problem; left taillight gasket leaks has ruined interior of the car; plastic trim at the base of my windshield is flapping in the wind; replaced stabilizer bar ends; engine coolant outlet housing was replaced due to a leak from the vent fitting - and to date I have at least 3 more things we have to look at before I can sell this heep.
