THE BLACK METAL STRIP ABOVE THE WINDSHIELD CAME OFF WHILE DRIVING. ALL THE PLASTIC CLIPS THAT ATTACH THE WINDSHIELD TO THE STRIP WERE BROKEN, AND SOME WERE EVEN MISSING UPON INSPECTION. I PURCHASED THE VEHICLE USED FROM A DEALERSHIP, AND GOT A CARFAX REPORT THAT SHOWED THE VEHICLE SUFFERED NO PRIOR DAMAGE AND HAD NO PRIOR ACCIDENTS WHATSOEVER. *TR

FOGGY WINDOW, ANTIFREEZE SMELL THROUGH VENT, PASSENGER SIDE FLOOR DAMP/WET. WAS TOLD BY DEALER THAT HEATERCORE O-RINGS AND HEATERCORE POSSIBLY NEEDS TO BE REPLACED. LOOKING FOR ALTERNATIVE SOLUTION TO RESOLVE THE PROBLEM. *TR

STARTED SMELLING "MAPLE SYRUP" IN PASSENGER COMPARTMENT. WINDOWS WERE FOGGING UP EASILY. THIS WAS CONFIRMED BY DEALER TO BE THE HEATER CORE LEAKING ANTIFREEZE, AND SERVICE COST $1,100. *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

Dec 09, 2009

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

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

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

THE HEATER CORE. I START SMELLING AN ANTIFREEZE SMELL INSIDE THE CAR THEN THE CHECK ENGINE SOON LIGHT CAME ON. ALSO THE TCL IS ON. THE DEALER SAID THAT IT IS A WHEEL SENSOR THAT WILL RUN ME $625. THE HEATER CORE IS $1,200. EVERY ONE THAT I TALK TO ON THE EMAIL SIGHT IS HAVING THE SAME PROBLEM. PLEASE HELP! THANKS. *TR

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

TL* THE CONTACT OWNS A 2002 MITSUBISHI DIAMANTE. WHILE DRIVING AT 45 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE DEALER WAS UNABLE TO DIAGNOSE THE CAUSE OF THE FAILURE AND STATED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 02V100001 (ELECTRICAL SYSTEM.) THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 65,289.

HEADLIGHTS TURN OFF FOR A SPLIT SECOND WHILE DRIVING DOWN THE HIGHWAY. IT DOES THIS WHEN THE AC SYSTEM KICKS IN. LIGHTS ON THE INSIDE OF THE VEHICLE DIM AS WELL. THIS HAPPENS AT BOTH IDLE AND HIGH RPM. A VOLT METER SHOWS A LARGE VOLTAGE SPIKE FOR A SHORT PERIOD OF TIME. THE VOLTAGE REGULATOR IS NOT RESPONDING FAST ENOUGH TO PICK UP THE VOLTAGE. HAVE WORKED FOR OVER A YEAR WITH MITSUBISHI TO ATTEMPT TO GET THIS RESOLVED. THEIR MECHANICS AT 2 DEALERSHIPS SAY THAT THE PROBLEM ISN'T NORMAL UNTIL THEY DON'T FIGURE OUT THE PROBLEM. THEN THEY COME BACK AND SAY IT'S NORMAL. I HAVE YET TO SEE A CAR DO THIS - ESPECIALLY WITH THE LIGHTS TURNING OFF WHILE DRIVING DOWN THE HIGHWAY. IF THE PROBLEM WAS "NORMAL" THEY WOULDN'T HAVE TAKEN MY CAR INTO THE SHOP TO INVESTIGATE THE PROBLEM IN THE FIRST PLACE -- WHY SPEND HOURS TRYING TO FIND A BAD WIRE IF THE PROBLEM IS "NORMAL". I FEEL THIS IS A POSSIBLE SAFETY ISSUE, AND THE MITSUBISHI DISTRICT MANAGER REFUSES TO AUTHORIZE THE SERVICE DEPT TO REPLACE MY ALT. OR BATTERY TO SEE IF IT WILL RESOLVE THE PROBLEM. THIS HAS HAPPENED SINCE THE FIRST MONTH I HAD MY CAR, AND CONTINUES TO HAPPEN NOW THAT THERE IS 20000 MILES ON THE VEHICLE. NUMBER OF FAILURES IS HARD TO ESTIMATE SINCE IT IS A CONSTANT ISSUE EVERY TIME THE AC KICKS IN AT NIGHT. WILL PUT 180 ASSUMING 15 TIMES DRIVING AT NIGHT PER MONTH. *JB

Feb 28, 2009

THIS IS THE SECOND TIME I AM COMPLAINING ABOUT THE SAME PROBLEM. THE END OF JUNE 2006 I DROVE TO WORK AND REACHED DOWN TO PICK SOME STUFF UP OFF THE PASSENGER SIDE FLOOR MAT. IT ENDED UP BEING SOAKED. AT FIRST I THOUGHT SOME WATER HAD COME IN BECAUSE THE PAST FEW DAYS OUR AREA HAD TORRENTIAL RAINS. WHEN I GOT HOME THE NEXT DAY I TOOK UP THE FLOOR MAT TO DRY IT OUT AND NOTICE ALL THE LIQUID UNDER IT WAS GREENISH YELLOW. IN MY MIND I WENT CRAZY BECAUSE THE SAME THING HAD HAPPENED TO ME A YEAR AND 2 WEEKS EARLIER. ONCE AGAIN THE HEATER CORE BECAME FAULTY AND POURED THE ENGINE COOLANT INTO THE PASSENGER SPACES. WONDERFUL, SINCE MY WIFE WAS 8 MONTHS PREGNANT, GREAT FOR HER TO BE BREATHING THOSE CHEMICALS. I HAVE TO SAY I WAS FORTUNATE THAT IT DIDN'T LEAK ON ANY OF THE COMPUTER COMPONENTS, LIKE HAS HAPPENED TO OTHERS, ESPECIALLY WHILE I WAS DRIVING. WOULD HAVE DEFINITELY CAUSED A SAFETY ISSUE. IT JUST BLOWS MY MIND THAT I HAVE HAD TO PAY FOR THE SAME SERVICE TWICE IN ABOUT A YEAR, ON A CAR THAT HAS LESS THAN 80,000 MILES ON IT. I REALLY HOPE THE NHTSA LOOKS INTO MAKING THIS A RECALL ISSUE, BECAUSE IT IS JUST HAPPENING TO TOO MANY CONSUMERS. JUST IMAGINE ALL THOSE PEOPLE WHO DON'T EVEN KNOW THEY CAN FILE A COMPLAINT. YES, I KNOW THERE WERE NO DEATHS OR INJURIES IN MY CASE, BUT WHEN THE COOLANT LEAKS ON THE COMPUTER BRAIN OF THE CAR, IT COULD BECOME A REAL ISSUE IF DRIVING ON THE HIGHWAY OR NAVIGATING CROWDED STREETS IN TOWN. THE POWER STEARING OR ANTILOCK BRAKES WOULD SHUT DOWN IF THE COMPUTER CRASHED FROM GETTING WET.

2 complaints

GOODYEAR EAGLE TIRES, MAKE WINDING NOISE WHEN VEHICLE IS IN MOTION. DEALER CLAIMED THAT THIS WAS CAUSED BY LACK OF TIRE ROTATION, I HAVE ROTATED THIS TIRES EVERY 6,000 MILES, SINCE THE DAY I BOUGHT THE CAR NEW. THE PROBLEM STARTED AFTER THE CAR HAD ABOUT 2,000 MILES, CAR HAS BEEN TO THE DEALER TWO TIMES AND THE PROBLEM HAS NOT RESOLVED, VEHICLE HAS 24,000 MILES, IT CAME WITH 36,000 MILES BUMPER TO BUMPER WARRANTY. I THOUGHT THAT WHEN YOU BUY A NEW CAR THE TIRES ARE ALSO UNDER THE ORIGINAL WARRANTY, BUT EVIDENTLY THE DEALER DOES NOT WANT TO HONOR THIS. IT IS UNFORTUNATE THAT THE MITSUBISHI MANUFACTURER HAD USED THESE CHEAP MADE TIRES ON A GOOD VEHICLE LIKE THIS. *LA

AT ABOUT 95000 MILES I NOTICED THE VEHICLE BECOMING VERY HARD TO DRIVE WHENEVER THERE WAS SLIGHT MOISTURE OR SNOW ON THE ROADS. AFTER INSPECTING I NOTICED BOTH REAR WHEELS TIPPED IN AT THE TOP SUBSTANTIALLY. THE LEFT REAR WHEEL WAS ALSO TOWED OUT AT THE FRONT AND BOTH REAR TIRES WERE ALMOST COMPLETELY WORN EVEN THOUGH I HAD JUST REPLACED THEM ABOUT 25000 MILE PRIOR. I TOOK IT TO A LOCAL SHOP WHO INFORMED ME THAT THERE WAS A TECHNICAL SERVICE BULLETIN OUT FOR BUSHINGS THAT PRESS INTO THE REAR KNUCKLES WEARING PREMATURELY. I HAVE SINCE MOVED THE FRONT TIRES TO THE REAR AND THOSE HAVE COMPLETELY WORN OUT. I UNDERSTAND I WILL NEED TO HAVE THESE BUSHINGS REPLACED AND HAVE THE SUSPENSION ALIGNED TO FIX THE PROBLEM. THIS IS A HUGE EXPENSE AND WITHOUT KNOWING WHAT TO LOOK FOR THE VEHICLE GOES FROM A NICE RIDE TO ALMOST IMPOSSIBLE TO DRIVE IN A VERY SHORT TIME. I BELIEVE THIS IS A HUGE SAFETY CONCERN AND ALOT OF PEOPLE WILL BE UNAWARE OF THE PROBLEM OR CONTINUE TO DRIVE THE VEHICLE THIS WAY BECAUSE IT IS VERY EXPENSIVE TO FIX. *TR

IN THE WINTER THE INSIDE OF MY CAR BECOMES A FOG ALL OVER MY WINDOWS AND IT WONT STOP FOGGING UP. A SMELL IS COMING OUT OF MY VENTS LIKE A COFFEE SMELL & IM INHALING THIS SMELL WHENEVER IM IN THE CAR I HAVE TO GO TO A DOCTOR TO GET CHECKED OUT TO SEE IF I HAVE HEALTH ISSUES .MY SUN ROOF LEAKS WHEN IT RAINS,I TOOK MY CAR BACK TO THE DEALER TO HAVE ALL THESE ISSUES FIXED BUT THEY NEVER DID I PURCHASED THE CAR IN 02 THE WARRANTY LASTED 02-05 B/C THAT IS WHEN MY WARRANTY EXPIRED.

I HAVE A 2002 MITSUBISHI DIAMANTE. I HAVE KEPT REGULAR MAINTENANCE. I AM SUBMITTING THIS FORM BECAUSE OF A HEATER CORE ISSUE I AM HAVING. HOWEVER I HAVE HAD THE FOLLOWING PROBLEMS WITH THIS CAR. ALL THESE PROBLEMS SEEM TO BE RECURRING PROBLEMS THAT HAPPEN TO MANY PEOPLE WITH THIS MODEL. AT LEAST THAT IS WHAT I FIND WHEN I SEARCH THE ISSUES ON THE INTERNET 1- VIBRATION IN STEERING WHEEL --THIS HAPPENED MULTIPLE TIMES AFTER TAKING CAR BACK TO DEALER-IT APPEARS THERE IS A KNOWN ISSUE WITH THE ROTORS IN THIS CAR. AFTER HAVING THE ROTORS CUT TWICE BY THE DEALER WITH NO LONG LASTING SUCCESS. I HAD TO HAVE THE BRAKES AND ROTORS REPLACED BY A MECHANIC ( CAR HAD LESS THE 10,000 MILES WHEN ISSUE STARTED HAPPENING) 2- RUSTED MUFFLER--NOT SURE IF THIS ISSUE HAPPENS OFTEN BUT AFTER 23,000 MILES I HAD TO HAVE MY MUFFLER REPLACED BECAUSE THERE WAS A HOLE RUSTED THROUGH THE TOP OF IT-I WAS TOLD THIS COULD HAPPEN FOR NOT USING THE CAR VERY MUCH IN THE WINTER TIME( ROAD SALT CAN CAUSE THE RUST) 3- HEATER CORE- I KNOW HAVE A HEATER CORE PROBLEM IN THIS CAR. I HAVE ANTIFREEZE LEAKING IN PASSENGER COMPARTMENT. I HAVE AN ANTIFREEZE SMELL IN THE CABIN OF THE CAR. MY WINDOWS FOG AND THE DEFROSTER WILL NOT CLEAR THE WINDSHIELD ( MAKES IT WORSE). I AM LOW IN ANTIFREEZE BECAUSE OF THIS. MY SERVICE ENGINE LIGHT HAS NOW COME ON AND I AM TOLD THIS CAN BE CAUSED BY LEAKING ANTIFREEZE ONTO THE COMPUTER WHICH IS POSITIONED UNDER THE HEATER CORE. THIS ISSUE IS WIDELY REPORTED ON THE INTERNET IN MANY FORUMS AND SEEMS EVERYBODY WITH A DIAMANTE WILL EVENTUALLY HAVE THIS PROBLEM. I AM BEING TOLD THIS REPAIR CAN COST OVER 1,000 DOLLARS 4-I HAVE HAD TO REPLACE 3 SENSORS IN THE ENGINE 2 EGR AND 1 IDLE SENDER (COST AROUND 1,500 DOLLARS). THIS MAY OR MAY NOT BE BECAUSE OF THE HEATER CORE ISSUES CAUSING THE CARS COMPUTER TO FAIL. *TR

I PURCHASED A USED 2002 MITSUBISHI DIAMANTE IN AUGUST 2005. THE CAR HAD 45,000 MILES ON IT. IN OCTOBER WHEN I STARTED TO USE THE HEATER I COULD SMELL AN UNUSUAL SMELL INSIDE THE CAR. IN JANUARY OF 2006 MY BROTHER RODE IN THE CAR AND TOLD ME THE SMELL WAS ANTI-FREEZE. I WENT ON THE INTERNET AND INSTANTLY FOUND OUT THAT THIS MODEL CAR HAS A PROBLEM WITH THE HEATER CORE O-RINGS FAILING. THE SMELL IN THE CAR GOT REAL BAD REAL QUICK AND I HAD TO HAVE THE LEAKING O-RINGS REPAIRED. I WOULD GET SICK FROM THE SMELL AND HAD NO CHOICE BUT TO HAVE IT FIXED. I BROUGHT THE CAR TO A MITSUBISHI DEALER AND HAD THE REPAIR DONE FOR $650.THE CAR HAD 48,000 MILES ON IT WHEN THE REPAIR WAS MADE. THAT IS ALOT OF MONEY FOR PROBLEM THAT MITSUBISHI SHOULD HAVE CORRECTED. *JB

TOOK IT TO THE DEALER, THEY DID NOT FIND ANYTHING, SO I PICKED UP THAT SAME AFTERNOON, NEXT MORNING SAME PROBLEM. I TOOK THE CAR BACK ON JAN 19, LEFT IT OVER NIGHT AND THEY FOUND IT TOOK A COUPLE OF MINUTES TO GO INTO GEAR, THEREFORE, THEY DECIDED TO LOOK AT THE TRANSMISSION, THE CAR HAS BEEN AT THE DEALER SINCE 1/20 THRU 2/7, AFTER SEVERAL DISCUSSIONS THEY HAVE TOLD ME IT IS THE HEATING CORE DRIPPING ON TOP OF THE COMPUTER DAMAGING THE SENSORS, TODAY 2/8 THE CAR WOULD NOT GO INTO GEAR AT ALL. I HAVE HAD GREASE WITH THE SEAT BELTS, THEY HAD TO BE CHANGED AT 3600 MILES, THE TIRES (EAGLE) HAD TO BE REPLACED AT 18,000MIES, THE BRAKES STARTING ACTING UP AT 6000 MILES, THE STEERING STARTED VIBRATING AT 12,000 MILES. BOTTOM LINE THIS CAR IS A MESS, SUCKS AND MITSUBISHI DOES NOT WANT TO BE RESPONSIBLE FOR ANY OF THOSE PROBLEMS, THIS IS A BIG LEMON!*AK
