Mitsubishi Diamante Problems

The automatic transmission may fail prematurely

The automatic transmission may fail prematurely requiring overhaul or replacement of the transmission.

Coolant Leak From Heater Core

A coolant leak may develop from the heater core, requiring replacement of the heater core.

Brake Pedal Pulsation

A brake pedal pulsation may be noted on brake apply. This is commonly caused by warping of the front brake rotors. Our technicians remind us that re-machining (turning) the rotors can correct this issue but the repair may last only a short time as the thinner rotors would be even more prone to warping. Replacement of faulty rotors with high quality parts is often the best option in these situations.

2003 Mitsubishi Diamante' LS -- Very nice This has been my favorite car that ive owned so far. The luxury aspect of it reeled me in. The heated leather seating smooth ride. The fact that the memory buttons on the driver door always adjusted to my comfortable seating position AS i was getting! yaaa THATS NICE
I bought the car with 20,000 miles on it and the abs light came on in the first storm. I didn't have the pump replaced, too pricey. I now have 108,000 miles on it, have always had it serviced, but the valve cover gaskets are leaking now. I have had some brake jobs done and things like that but I think they did a lousy job, they have always squealed since. I don't like how low the front end is, ...
