I have a 2003 mitsubishi diamante ls with 71677 miles on it all of the sudden my husband (the primary driver) tells me that every time he gets out of the car he feels light headed and nauseous. Days later the front windshield started fogging up while driving and after turning the car off (whether it is warm or cold outside) I googled why would this happen and have spoken with a few mechanics and they are telling me that it is the heater core going out, and that the reason why my husband is getting light headed and nauseous is because there is anti-freeze coming into the interior of the car which is very detrimental to your health. I have read a ton of complaints on different websites and they all say the same thing. I contacted mitsubishi corporate today and spoke with a [xxx] in customer service and explained to her what was going on and asked why mitsubishi has not done anything about this. First because of the health implications, secondly because of the safety issue of the windshield fogging up while you're driving to where you can't see and thirdly that from reading the complaints, the heater core is right above the computer in the car so if the heater core is leaking antifreeze, it could fry the computer and cause a possible crash if the car were to stop suddenly. She said that "seeing that I hadn't had the car into a dealership in the last year that there is nothing they can do about it". I told her that it just started and what was I suppose to do, look into my crystal ball and know a year ahead of time that the heater core was going to go out. This is ludicrous! ! ! Mitsubishi knows that this is a serious issue and are not doing one thing to fix it (by issuing a recall) where do we diamante owners go to get some help? Do we need to file a class action lawsuit as that seems like the only way a fire is going to get lit under them (corporations tend to act if it means losing tons of money) the car can't be driven and I'm still paying on it.

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. All diamantes need to be recalled and the heater core and/or its o rings fixed or replaced. If this doesn't happen, people will die when they suddenly cannot see the road through their front windshield. [xxx] *tr

I have a 2003 mitsubishi diamante with 60,000 plus miles. For the past several months I have noticed a strong smell of anti-freeze coming from the vents and the windows constantly fogging up, sometimes to the point that I cannot see to drive. I have read many similar complaints and agree with others that mitsubishi needs to issue a recall for the heater core, as I am sure this is the problem. I have yet to take mine in to get it repaired, so I don't have a cost quote at this time.

I purchased a used 2003 mitsubishi diamante from bankston dodge in 2007. It was clean and ran well. There was an unusual odor inside, but smelled as if it could have been what the dealership used to clean the inside. It turned out to be anti-freeze. The vehicle had a heater core leak prior to our purchase. Recently the gas gauge has stopped working.
