2003 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.

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, ...
I just purchased this car from a local dealer. It has 66k miles and so far everything seems to be okay. I did have the "service engine soon" light come on after a brisk breeze down a nicely paved rd (about 95 for less than a quarter mile). Culprit=O2 sensor. But the light has since gone off and not come back on. I will be tuning it up soon because it idles a little rough for my taste. slightly ...
