“JUST LIKE EVERYONE ELSE WITH A 2002 MITSUBISHI DIAMANTE, I HAVE HAD HEATER CORE PROBLEMS. ANTIFREEZE LEAKING/SMELL AND WINDOWS FOGGING UP. COST TO REPAIR EXCEEDS $1000. IF EVERY ONE OF THESE VEHICLES HAS THIS SAME ISSUE, WHY HAS IT NEVER BEEN RECALLED? AND WHY DOES MITSUBISHI GET AWAY WITH ALL CARS HAVING THIS DEFECT? AND WHY HAS THIS INVESTIGATION NOT RESULTED IN ACTION? IS THERE ANOTHER AGENCY THAT CAN GET RECALL ACTION FROM MITSUBISHI? *TR”

“MY FRONT WINDSHIELD WAS FOGGING UP EVERY TIME I USED THE HEATER AND A SMELL OF COOLANT INSIDE MY CAR--NASTY FILM WAS LEFT, FOUND OUT IT WAS A HEATER CORE PROBLEM. SOMETIMES THE FOG WOULD TAKE 20 MINUTES TO CLEAR UP WITH DEFROSTER ON HIGHEST SETTINGS. THESE PROBLEMS ARE ALL OVER THE INTERNET WITH MITSUBISHI DIAMANTES. I AM SURPRISED THAT THESE HAVE NEVER BEEN RECALLED FOR SAFETY REASONS. *TR”

“OUR 2002 MITSUBISHIS DIAMANTE VR-X HAS BEEN MISTING FROM THE HEATER CORE FOR A FEW YEARS. THE PROBLEM IS BAD GASKETS (O-RINGS) THAT JOIN THE HEATER CORE WITH THE LINES FOR THE HEATER HOSES. THE HEATER CORE IS INSTALLED RIGHT OVER THE PCM UNIT. IF IT LEAKS BADLY ENOUGH, THE PCM AND TRANSMISSION RELAY WILL BE DESTROYED. IT (HEATER CORE) FAILED SHORTLY AFTER THE WARRANTY EXPIRED AND WHEN WE WENT TO MITSUBISHI DEALER, THEY REFUSED TO FIX IT. THEY QUOTED US $1400.00 FOR REPAIRS. ON THE INTERNET, THERE ARE HUNDREDS OF COMPLAINTS FOR THE SAME PROBLEM, BUT NO ONE HAS GOTTEN ANY SATISFACTION FROM MITSUBISHI. I PUT SOME RADIATOR STOP-LEAK IN AND THIS SEEMED TO HELP SOMEWHAT, BUT IT IS STARTING TO MIST AGAIN WITH ANTI-FREEZE IN THE PASSENGER COMPARTMENT. THIS IS A TOXIN AND IS DANGEROUS TO INHALE AND WILL JEOPARDIZE MY FAMILY'S HEALTH. *TR”

“MY 2002 MITSUBISHI DIAMANTE HAS O RING FAILURE IN THE HEATER COIL. I HAVE READ MANY COMPLAINTS THAT THIS IS COMMON ON THIS MODEL AND WOULD LIKE A RECALL ON THESE VEHICLES DUE TO THE EXTREME NATURE OF THE ISSUE. WITH THE FAILURE OF THE O RINGS COME POTENTIAL ANTI FREEZE VAPORS ENTERING PASSENGER COMPARTMENT AND CAUSING PHYSICAL DAMAGE TO ALL PASSENGERS. IT MAY ALSO CAUSE THE CAR TO OVERHEAT IN THE MIDDLE OF HEAVY STOP AND GO TRAFFIC AND CAUSE ACCIDENTS AND/OR DEATH. IT MAY ALSO CAUSE THE HEATING ELEMENT TO NO LONGER WORK AND PASSENGERS IN THE EXTREME WINTER CLIMATES MAY BE SUSCEPTIBLE TO PHYSICAL HARM OR DEATH. LASTLY, THIS IS A RAMPANT KNOWN ISSUE WITH THESE VEHICLES AND SHOULD BE CORRECTED AT DEALER COST. MY CAR COST ORIGINALLY $30,000. AND I WOULD EXPECT THE AMERICAN GOVERNMENT TO MAKE THESE COMPANIES BACK UP THE VEHICLES THEY ARE SELLING TO THE AMERICAN PUBLIC AND MAKE THEM SAFE AND WORTH THE MONEY THAT IS SPENT ON THEM. *TR”
