My wife and I noticed antifreeze odor coming in through vents. When our windows would fog, our defroster wouldn't work. Then our passenger side floor was soaked with antifreeze. We took the car to the dealer, our heater core was leaking. Cost was $1300 to repair. Mitsubishi should be held responsible!! Too many complaints.

For over 2 years now I have had problems with an odor in my 2000 diamanti and the defogger never seemed to work on the windows. A couple of weeks ago I saw something leak onto the passenger side rug but didn't' t guess that this could have something to do with the heater core. Upon taking it to my dealer I was told this was hole in the heater core that had to be fixed immediately because it was dangerous and hazardous to my health to breath the fumes that were coming out of the core. The cost would be approximately $1200. I noticed I often had headaches when I drove long distances but was very concerned when my grandchild became very car sick (which had never happened before) upon riding in my car. I still didn't associate the heater with our problems. I think this is very dangerous and something should be recalled on these. I resent that after only 40,000 miles I must spend $1200 on something that is obviously a mistake on mitsubishi's part since it is not a wear factor.

Front windshield fogs up, strong smell of anti-freeze, can't clear the fog with defogger, read potential risks to health because of the contact to anti-freeze fumes.

I currently have what is described to be a "heater core failure" in my 2000 mitsubishi diamante. I have been made aware that this issue is fairly common amongst diamantes. Any time I turn on the heater, my automobile is filled with a noxious odor that I'm lead to believe might be detrimental to my health. I am also unable to defrost my windows because of this problem. This causes a dangerous driving condition as I'm forced to constantly wipe the windshield with a paper towel.

Vehicle check engine light came on and locked into third gear. Noticed smell of coolant inside drivers compartment and hazing of the windshield. Brought vehicle to dealer to have problem improperly diagnosed and had to have it re-tested two weeks later. Heater core leakage has caused damage to the ecu and now both have to be replaced. Total cost of repair for both was $3,357.62. Coolant fumes are very toxic and cause a significant health risk and ecu failure could easily result in a very serious accident on the highway or elsewhere. The "fogging" of the windshield is a visibility hazard as well caused by the hot coolant in the defrost vents.

The heater core has failed for the second time. I purchased the car from a dealer with 54,000 miles on it and after 500 miles the heatercore is fried. The worst part is that when I went to the mitsubishi dealership to get my remote reprogrammed I got the printout of all the previous service that was done on it. The heater core was already replaced at 24,000 miles!!! Does this mean that I will have to spend around $1,000 every 25k miles that I drive the car??? Mitsubishi, please address this problem! Regarding to the problem itself... I got all the usual symptoms - the windshield was fogging up, there was a strong smell of the antifreeze in the car and now there's a pool of antifreeze by the passenger's seat. This cannot be good for my respiratory system... Antifreeze is a poison. I've had some problems with my lungs before and if it gets worse after this problem, mitsubishi will look at a huge lawsuit.

About two months after buying a 2000 diamante; in oct, 2004, I started to notice thick fog on the windsheild that wouldn't go away by using the de-fogger and when using the heater, I would also notice strong smell on anit-freeze comming out from the vent. Upon inspection, the dealership described the problem as faulty o-ring in the heater core. The fix was costly, around $1100.00 however the car has been problem free since then.
