2004 Mitsubishi Diamante Problems
A coolant leak may develop from the heater core, requiring replacement of the heater core.
The automatic transmission may fail prematurely requiring overhaul or replacement of the transmission.
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.
