“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.”
NHTSA complaint #10243955, filed 2008-09, 86,000 miles“Windows were not clearing properly and smell of anti-freeze was very strong. Upon calling the Mitsubishi dealer, I was told, it's probably the heater core. I ask if this is normal for a car less than three years olds with approximately 40,000 miles. The service manager told me, well to give you and idea, I just replaced one last week. I was told vehicle is out of warranty, cost to repair $650.”
NHTSA complaint #10008109, filed 2003-02, 41,175 miles“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.”
NHTSA complaint #10110292, filed 2005-02, 53,000 miles“Heater core on 2000 mitshubishi Diamante failed and fogged up my windsheild. While driving home the night of the failure, a deer jump in front of my car and caused 4 grand in damage. I had to pay for the heater core at the dealership.”
NHTSA complaint #10112052, filed 2005-02, 82,000 miles“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. …”
