| 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. in addition, the windshield is covered with a film that cannot be washed off from this leak. a recall should be issued for this problem, i am not the first person to file this complaint on your website. thank you.*ak | |||

| This is the second time the heater core has started to leak. it was replaced 40k miles ago and i was charged $ 1,000 for repair costs. having researched this, it is due to faulty heater core gaskets which mitsubishi replaced the defective gaskets with a redesigned one. the car is undrivable due to the toxic fumes from the ethylene glycol coming out of all the vents and i do not have the money to get it repaired. mitsubishi refuses to do anything about it, and nearly every diamante on the road has had this happen. the carpet is ruined from the coolant leak as well, and many have had the ecu for the transmission fail due to coolant leaking on it. *tr | |||

| 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. i am filing this complaint to ascertain that this is a very very common problem in mitsubishi diamante and mitsubishi motors should be aware of three main risk associated with this: (1) the defect exposes customers to unusual level of toxic ethylene glycol which should not exceed 10-25 ppm levels (consult msds for ethylene glycol) (2) the leak can affect the car's microprocessor and poses a severe hazard for drivers. (3) faulty heater core makes the visibility difficult due to fogging of wind shield thus putting the driver at greater risk. i will eventually fix the problem by spending $1000 after the summer if mitsubishi refuses to issue a recall. right now i am trying some radiator anti-leak to delay the costly repair. but i want nhtsa to be aware of the hazards that has been ignored by the manufacturer. *la | |||
