MY WIFE WAS DRIVING ON THE INTERSTATE WHEN THE TRANSMISSION FAILED AND WOULD NO LONGER PROPEL THE VEHICLE. I HAVE RESEARCHED THE PROBLEM AND MULTIPLE PEOPLE HAVE HAD THE SAME PROBLEM. I DON'T UNDERSTAND WHY NO RECALL HAS BEEN MADE. THIS IS A VERY HAZARDOUS ISSUE, ESPECIALLY IF YOU ARE TRAVELING ON AN INTERSTATE. SHE HAD TO COAST THE CAR OVER AND WAS RAPIDLY LOOSING SPEED, A VERY DANGEROUS SITUATION. THE PROBLEM IS A FAULTY PART IN THE TRANSMISSION CALLED A WAVE SPRING. IN EVERY F4A51 MITSUBISHI TRANSMISSION, THIS HAS BEEN AN ISSUE. THE WAVE SPRING BREAKS, BYPASSES THE FILTER, ENTERS THE PUMP GEARS AND BREAKS THE PUMP, ENDING IN TRANSMISSION FAILURE. IT IS A COSTLY REPAIR, $1800-$2000. IT IS A FAULTY DESIGN, AND A BETTER AFTERMARKET WAVE SPRING WAS EVENTUALLY ENGINEERED. THIS SHOULD BE A RECALL. *TR

THE HEATER CORE IS AN EXTREMELY DANGEROUS PROBLEM. THE WINDOWS IN THE CAR FOG UP SO BAD I COULDNT DRIVE THE CAR...HAD TO PULL OVER AND WIPE THE WINDOWS DOWN. BUT THE THING IS...I DIDNT KNOW WHAT THE PROBLEMS WAS...UNTIL I REALIZED THE WINDOWS WERENT JUST BEING FOGGED BY THE COLD, ECT IT WAS A TOXIC MIST FROM A HEATER CORE PROBLEM...I PULLED OVER 2 TIMES BECAUSE I GOT SICK...I NOTICED A MIST COMING OUT OF THE VENTS....SO ALL IN ALL I CALLED MITSUBISHI AND THEY REFUSE TO DO ANYTHING ABOUT THIS.THIS HEATER CORE PROBLEM CAN LEAD TO ACCIDENTS, SICKNESS, AND OTHE EXPENSIVE PROBLEMS IN THE CAR! THE FUMES ARE EXTREMELY TOXIC!!! THERE ARE 1000'S OF COMPLAINTS AND BLOGS ABOUT THIS PROBLEM...I'M SURE THERE ARE 100,000+ COMPLAINTS ABPOUT THIS PROBLEM. AND MITSUBISHI REFUSES TO HELP OR DO ANYTHING ABOUT THIS. I TOLD THEM, IS THIS GONNA TAKE A FATAL ACCIDENT FOR THEM TO DO SOMETHING?" THEY REPLIED, "IM NOT ANSWERING THAT!" I TOLD THEM THAT THEY SHOULD HAVE RECALLED THIS PROBLEM. THEY REPLIED, "SORRY BUT YOUR WARRANTY IS UP WE CAN'T DO NOTHING ABOUT IT." THIS HEATER CORE PROBLEMS LEADS TO FAULTY TRANSMISSION PROBLEMS, ELECTRICAL PROBLEMS, HAZERDOUS PROBLEMS, SICKNESS, INTERIOR OF THE CAR CAN BE RUINED BECAUSE ANITFREEZE LEAKS THROUGH THE DASH BOARD...WHERE MITSUBISHI PLACED THE HEATER CORE. MADE NO SENSE TO PLACE A HEATER CORE ABOVE THE ELECTRICAL COMPONENT OF THE TRANSMISSION. THEY REALLY MESSED UP HERE AND WILL NOT DO ANYTHING ABOUT THIS. I THINK THAT THE MEDIA SHOULD GET INVOLVED BECAUSE THEY PROBABLY WONT DO ANYTHING ABOUT IF SOMEONE DOESNT SPEAK UP! *TR

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

WHAT CAN BE DONE ABOUT THIS PROBLEM? *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

THERE SHOULD BE A RECALL, OWN A 2002 MITSUBISHI DIAMANTE. I JUST FOUND OUT THAT THE ANTI-FREEZE SMELL AND THE SMOKE COMING THROUGH THE VENTS IS BECAUSE THE HEATER CORE HAS GONE BAD. THE QUOTE I RECEIVED WAS FOR $1100. MY ANTENNA JUST STOPPED WORKING ON ME ALSO. IT DOESN'T GO DOWN ANYMORE, BUT THE MOTOR STILL SOUNDS LIKE ITS WORKING. WE ARE ALL HAVING TOO MANY OF THE SAME PROBLEMS. THE COMPANY SHOULD BE LIABLE. *TR

THE HEATER CORE OF THE 2002 MITSUBISHI DIAMANTE NEEDS TO BE RECALLED AND/OR REDESIGNED BY MITSUBISHI. AS IT IS, JUST ABOUT EVERY SINGLE POST I SEE ONLINE ABOUT THIS CAR HAS THE EXACT SAME PROBLEM. THE HEATER IS POSITIONED DIRECTLY ABOVE THE CAR'S COMPUTER , OR ECU , AND THEREFORE CAUSING PROBLEMS WITH THE ENGINE, TRANSMISSION, SUSPENSION, ETC.. THE ENTIRE 80-PAGE THREAD LINKED BELOW IS ALMOST COMPLETELY ABOUT THIS ISSUE : HTTP://WWW.CARSURVEY.ORG/VIEWCOMMENTS_REVIEW_76426.HTML THERE ARE MANY OTHERS LIKE IT. THE ISSUE IS MENTIONED IN TECHNICAL SERVICE BULLETINS BY MITSUBISHI BUT IS NOT RECALLED. PEOPLE ARE BUYING THIS CAR USED AND HAVING TO REPLACE THE HEATER CORE (AROUND $1200 REPAIR). *TR
