“The heater core has failed (once again) I am not sure of any company that has realeased their cars with such a major failure without taking some kind of responsibility to recall this item in the car. Nearly all of the heater cores from Mitsubishi diamantes that I have seen are all bad. Leaks onto the ecu and causes a whole heck load of problems. Please DOT have Mitsubishi recall this. …”
NHTSA complaint #10715681, filed 2015-05, 171,000 miles“This is a Mitsubishi Diamante 1998 es. I'm experiencing pungent smell of anti-freeze inside the car as soon as I turn on heating. The dealer I got the preowned car from won't fix the problem unless I can show them the leak in heater core. Anti-freeze contains ethylene glycon and the fumes are highly toxic. Fixing the the heater core will cost $1000. …”
NHTSA complaint #10082271, filed 2004-07, 91,000 miles“Windows fog up and cannot be cleared by the defroster. Very strong smell of anti-freeze inside the car. Smokey vapors come out of the heating vents. I'm having difficulty breathing while driving my car, and believe the cause of my nausea and headache is due to breathing anti-freeze vapors. Stain on passenger side of carpet. All these symptoms indicate a heater core problem.”
NHTSA complaint #10112060, filed 2005-02, 78,000 miles“I own a preowned 1998 mistubishi Diamante ls. When the climate control, particularly the heater is engaged, the smell of anti-freeze becomes quite apparent. Dealer claimed 2 years ago when I bought it that it was the smell of the chemicals used to clean the car during make-ready. Ethylen glycol fumes are toxic and this is a reoccuring defect in this model car from posts I have seen on various websites. I was later told that to fix this problem will cost close to $1000 since the car is out of warranty. Mitsubish issued a TSB addressing this problem, obviously they are aware of it. …”
NHTSA complaint #10100757, filed 2004-11, 58,000 miles“Failure of heater core gaskets resulting in fumes inside the car from anti-freeze; this is the 2nd time this has happened with this vehicle in the last 35,000 miles and the repair labor is estimated at 6 hours, which is around $1,000.”
