I have a '02 Mitsubishi Diamante and I have had problems out of the heater core leaking and now its affected my ecu (computer) I call the dealership and they want outrageous prices to fix or even check my car. . I think that since its a problem from the dealer they should recall these cars. . I know I will never buy another Mitsubishi and I will never recommend them to a friend. . What can be done about this problem?.
Transmission retaining rings brake and jam gears. Car stopped in intersection had to be pushed off road and towed to shop replaced transmission. Was told by repair person that this is something that Mitsubishi knew was happening for the last 2 years.
Heater core defective and leaked coolant underdash on to transmission ecm and neutral safety switch. Because of this very common manufacture defect I had to have my heater core, transmission ecm, neutral safety switch replace. And my transmission rebuild, none of which were warranted by the manufacture and were not cheap.
