Mitsubishi Diamante Problems

Coolant Leak From Heater Core

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

The automatic transmission may fail prematurely

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

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.
