1998 Mitsubishi Diamante Problems

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

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.

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

1998 Mitsubishi Diamante Reviews

Probably the best car I've ever owned. Smooth, powerful, reliable and a dream to drive. Owned it for 6 years and have had to do only minor maintenance. Just replaced the cam belt at 61,000 miles.

the exterior body, like the bottom of the doors come off if you are to close to the side walk and you get in and close the door, and to find the plastic grips is a pain, when i finaly got em the next day the same thing happened, other wise the car is the best one i owned.
