Mitsubishi Diamante Problems
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.
The seat belts may not properly retract due to an internal fault with the retractor mechanism. Replacement of the seat belt retractor would be required to correct this concern.
There have been reports of airbags not deploying in the event of a frontal impact. Some claim that a shorted airbag wire harness can cause this to occur. Unfortunately there is no diagnoses that will isolate this problem other than fault codes stored in the airbag control module. Our technicians recommend to have any airbag light issues diagnosed and repaired in order to help ensure the airbags will deploy when needed.

Mitsubishi Diamante Reviews
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, it scrapes over low bumps and such. The interior is perfect (leather) all the fancy upgrades work except the heater never works down on the floor, just in the middle. A/C is great, speakers are a bit blown but think it was done at a shop when I had body work done, it was a great system. I have put a LOT of stop and go miles on it going to work and that is part of the problem with brakes and such. Its been a good car but think its getting tired. Not as good as a Toyota or Honda for sure.
