2000 Mitsubishi Diamante: problems, recalls and reliability

“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.*jb”Owner report · Visibility · Oct 2005

“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. *jb”Owner report · Visibility · Oct 2005

“The fumes of antifreeze fogged up the windows severely, reducing visibility of the driver. It was raining one night and my windows all of a sudden got foggy. I turned on the defroster, which made my windows even foggier. The poor visibility caused me to run off the road into the grassy median. I was out of town when this occurred. In doing research on this problem I found that it was common all diamantes (92 -2001). In many cases, the driver is not aware that this is a severe problem. The antifreeze will started leaking on the passenger?s side area. Causing more strong smell of toxic antifreeze. I believe this to be a safety issue. *ak”Owner report · Engine And Engine Cooling · Mar 2005

“Windows fog constantly and I can not get them defrosted. Smoke and smell of antifreeze comes into cabin of car. Took to dealer a year ago and was told nothing was wrong, car now has 98,000 miles and they are telling me it will cost 672.00 to replace the heater core. I have found several complaints about the same issues. I became ill in january of this year, the doctors (4 of them and three hospitals, ct scans, etc) could not figure out what it was. Turns out it was breathing the fumes in my car. At that time, the smoke only appeared a couple of times, but now it has increased considerably. I think it's sad that mitsubishi will not repair this problem, nor have they corrected it.*ak”Owner report · Visibility · Dec 2004
