How reliable a car is the Mitsubishi Diamante?

Answer

My wife has a 2003 Mitsubishi Diamante and I have to say that it is BY FAR the WORST car I have ever seen. The brakes seems to need service (new pads) every 5000 miles, fuel gauge has never worked correctly (we have given up and just reset the trip meter and fill up at 300 miles), have to replace the o2 sensors, transmission had to be rebuilt, it just never seems to idle correctly...the list goes on. The worst thing (and apparently many others have had the same problem) was a major leak in the heater core at 55,000 miles that soaked the inside of the car in addition to flooding the ventilation system. A mess to say the least. Currently, the car has 83,000 miles and I honestly cannot see it hitting 100,000. For the record, I am a weekend mechanic, am pretty good at car maintenance and at least VERY good at taking care of cars, so far as sticking to a maintenance schedule. It doesn't matter with this car. It is just awful. I drove $1000 cars for years and would go back to that in a heartbeat. I never had this much trouble, even then. STAY AWAY.

^i wouldnt put too much faith in this guy as he is globally generalizing based on only owning one car. I work exclusively on maintaining and performance modifications on the diamante and 3000gt platform. the second gen diamante is not a terrible car by anymeans in fact the bang for the buck is unsurpassed! Sorry for his bad experience but i have one with 150k miles on it as my dd and it has only needed basic maintenence EVER! i think his problem may be that he is assuming he knows what he is doing with these cars (they have to be cared for very specifically often with specific fluids) and screwed it up worse. (also 50k in between pads on multiple occassion with these cars, get quality products and they treat you right)

I have an 03 Diamante also, and by far, it is the BEST car Ive ever owned in terms of maintenance and reliability. In saying that Ive had a 89 Mazda Familia XG Turbo, 94Pulsar GTiR, 98 BMW 318i (which was the worst of them all).

Its low maintenance, quick and decent sized for a family sedan. Maybe because the Diamante was Australian assembled?? or maybe because we got it brand new. I feel sorry for that guy whos Diamante was giving him crap, but as for mine, its been a great car. Even pimped it up and looks SWEET!
