I have a new 2003 mitsubishi diamante, which Ive taken back to the dealership 3 times now with the same two issues: the front breaks make noise and my stearing wheel vibrates when I brake and the check engine service soon light keeps coming on. One of the dealers employees told me that the brakes issues was very common as sometimes the cars sit for a long time in a lot before they are sold. This does not make feel safe driving this vehicle at this moment.

The factory tires on this vehicle are bad. I have gotten 3 flat tires in the last 2 weeks. They wear down extremely fast and blow out very easily.

June 2004

I own a 2003 mitsubishi diamante ls with 70,000. I purchased the car from the dealership brand new. In november 2007, there was a strong smell of antifreeze in the car. After some investigation, it was discovered there was a leak in the heating core, which was causing the antifreeze to leak out of the compartment and into the cabin of the car...needless to say, the car is undriveable because of the health risks associated with breathing antifreeze. Estimated repairs are around $1500.

Information redacted pursuant to the freedom of information act (FOIA), 5 u.s.c. 552(b)(6). This concerns my 2003 mitsubishi diamante. It has less than 50,000 miles on it and it has suddenly started spewing a light film on the inside of my front windshield so that I cannot see well...and not at all when I am headed into the sun. I have checked on the internet and a lot of people are having the same problem with mitsubishi diamantes going back several model years.
