• 12/23/2007· VISIBILITY

  I OWN A 2003 MITSUBISHI DIAMANTE LS WITH 70,000. I PURCHASED THE CAR FROM THE DEALERSHIP BRAND NEW. IN NOVEMBER 2007, THERE WAS A STRONG SMELL OF ANTIFREEZE IN THE CAR. AFTER SOME INVESTIGATION, IT WAS DISCOVERED THERE WAS A LEAK IN THE HEATING CORE, WHICH WAS CAUSING THE ANTIFREEZE TO LEAK OUT OF THE COMPARTMENT AND INTO THE CABIN OF THE CAR...NEEDLESS TO SAY, THE CAR IS UNDRIVEABLE BECAUSE OF THE HEALTH RISKS ASSOCIATED WITH BREATHING ANTIFREEZE. ESTIMATED REPAIRS ARE AROUND $1500. THIS IS COMPLETELY RIDICULOUS!!!! I AM OUTRAGED TO SEE THAT SO MANY 2003 DIAMANTE OWNERS ARE HAVING THE SAME PROBLEM. I BELIEVE AN INVESTIGATION NEEDS TO BE CONDUCTED, AND MITSUBISHI MOTORS SHOULD BE HELD ACCOUNTABLE FOR THIS!!! *TR

• 12/08/2007· ENGINE AND ENGINE COOLING,VISIBILITY

  THIS IS A MITSUBISHI DIAMANTE 2003 ES. I'M EXPERIENCING A SWEET SMELL OF ANTI-FREEZE INSIDE THE CAR AS SOON AS I TURN ON HEATING. ANTI-FREEZE CONTAINS ETHYLENE GLYCON AND THE FUMES ARE HIGHLY TOXIC. FIXING THE HEATER CORE WILL COST $1300. 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 WINDSHIELD THUS PUTTING THE DRIVER AT GREATER RISK. I WILL EVENTUALLY FIX THE PROBLEM BY SPENDING $1300 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. *TR

  THERE IS A ROTTEN EGG SMELL, ALL THE TIME. I'VE TAKEN IT IN TO THE DEALER 3 PLUS TIMES, AND EACH TIME THEY TELL ME THERE IS NOTHING WRONG, AND THAT I AM USING CHEAP GAS. THEY SUGGUESTED CHANGING GAS STATIONS. IT STILL SMELLS NO MATTER WHERE I GET THE GAS.*AK

• 11/15/2004· SERVICE BRAKES, HYDRAULIC,EQUIPMENT

  BRAKES VIBRATE WHEN APPLIED. I HAVE RETURNED MY '03 DIAMONTE FOUR TIMES FOR REPAIRS AND EACH TIME THEY STATE THAT THE ROTORS WERE WARPED AND EITHER REPLACED OR MACHINED THEM. BRAKES ARE NOW VIBRATING AGAIN AND WILL NEED TO BE RETURNED FOR REPAIR OR REPLACEMENT. WIND NOISE COMING FORM THE DRIVERS SIDE WINDOW. WINDOW ADJUSTMENTS WERE MADE THREE TIMES STILL HAVING NOISE PROBLEMS. RETURNED THREE TIMES TO HAVE LUMBAR SUPPORT SWITCH REPLACED. *AK

• 11/13/2004· TIRES

  EAGLE LS KEEPS LOSING TIRE PRESSURE (ABOUT 10PSI) EVERY 5-7 DAYS. HAVE WENT TO THE MITSUBISHI DEALERSHIP 4 TIMES NOW FOR THE PROBLEM AND THEY SAID TO GO SEE A GOODYEAR SERVICE CENTER. GOODYEAR SAYS THE TIRE JUST NEEDS AIR AND IT'S OK. THIS CANNOT BE SAFE IF THE TIRE IS CONTINUALLY LOSING AIR PRESSURE IN SUCH A SHORT TIME FRAME. *JB

• 11/08/2006· ENGINE AND ENGINE COOLING,VISIBILITY

  2003 MITSUBISHI DIAMANTE WITH 65000 MILES. NOTICED FOG COMING OUT OF VENTS AROUND THE RADIO. IT SMELLED LIKE ANTI-FREEZE AND CREATED A FOG ON MY WINDOWS THAT WAS BAD ENOUGH TO RENDER THE CAR UNDRIVEABLE. I WAS ALSO GETTING AN ERROR MESSAGE OF P-1751. THIS REFERS TO A PROBLEM WITH THE TRANSMISSION RELAY CONTROL. I TOOK THE CAR TO A TRANSMISSION SHOP AND AFTER DIAGNOSING FOR TWO DAYS, THE MECHANIC TOLD ME THAT HE HAD DISCOVERED A LEAKING HEATER COIL THAT MAY OR MAY NOT HAVE DAMAGED THE PCM. WORST CASE SCENARIO, $1600. IT WILL AT LEAST COST $500, BEST CASE SCENARIO. I UNCOVERED NUMEROUS COMPLAINTS FROM DIAMANTE OWNERS WITH MODELS FROM A WIDE RANGE OF YEARS WHO WERE EXPERIENCING THE SAME PROBLEMS. THIS IS CRIMINAL NEGLIGENCE AND I PERSONALLY REQUEST AN INVESTIGATION TO RESEARCH HOW MISTUBISHI HAS BEEN GETTING AWAY WITH THIS, FOR SO LONG. THE SAME EXACT PROBLEMS ARE OCCURRING ON A FREQUENT BASIS. *JB

• 11/05/2007· ENGINE AND ENGINE COOLING

  2003 DIAMANTE ISSUES. STARTED SMELLING A SYRUPY TYPE SMELL, COOLANT SMELL THROUGHOUT THE CABIN AND HAD FUMES ESCAPING THROUGH THE VENT IN THE CAR. COOLANT LEVEL DROPPING WITH NO VISIBLE SIGNS ON THE GROUND. LOOKS TO BE THE HEATER CORE. NOTHING HAS BEEN DONE YET. SEEN MULTIPLE COMPLAINTS REGARDING THE SAME ISSUE AND ON THIS SITE. WONDERING WHY SO MANY COMPLAINTS HAVE BEEN SENT, BUT NOTHING DONE YET? *TR

• 10/28/2008· ENGINE AND ENGINE COOLING

  I OWN A 2003 DIAMANTE WITH ABOUT 60,000 MILES ON IT. MY WINDOWS CONTINUALLY FOG UP WHILE DRIVING OR PARKED AND THE DEFROSTER/VENTS DOES NOT ELIMINATE THE FOG AT ALL, MAKING DRIVING VERY DIFFICULT AND DANGEROUS ESPECIALLY IN RAINY WEATHER AND DURING THE NIGHTTIME. THE SMELL OF ANTIFREEZE IS EXTREMELY STRONG INSIDE THE VEHICLE. I HAD A PROBLEM WITH MY TRANSMISSION SHIFTING AND THE LIGHT AROUND THE "N" ON THE INSTRUMENT PANEL WAS FLASHING. THE MECHANIC SAID MY HEATER CORE WAS LEAKING COOLANT ONTO THE TRANSMISSION CONTROL MODULE CAUSING IT TO MALFUNCTION. I WAS TOLD THAT EVEN THOUGH I PAID FOR AND HAVE AN EXTENDED WARRANTY ON THIS VEHICLE IT WOULD NOT BE COVERED BECAUSE THE HEATER CORE LEAKING IS WHAT CAUSED THE TRANSMISSION CONTROL MODULE TO FAIL. THE HEATER CORE WAS REPLACED ALONG WITH THE CONTROL MODULE AND THE RELAY WITH A COST OF OVER 2,500 DOLLARS. IT SEEMS LIKE A PROBLEM LIKE THIS THAT IS EXTREMELY COMMON IS THESE VEHICLES, CREATES SAFETY AND HEALTH HAZARDS, AND VERY EXPENSIVE TO FIX SHOULD BE RECALLED AND COVERED UNDER WARRANTY. *TR

  IN RESEARCHING WHAT MIGHT BE WRONG WITH MY MITSUBISHI GALANT HEATER, I FIND IT IS A COMMON PROBLEM DESCRIBED TO THE TEE.

I THINK CAR RUNS VERY RUFF AND IM NOT SURE WHAT IT IS.. I BELIEVE IT'S THE TRANSMISSION FROM READING ALL THE POST ON HERE.. AND ALSO THE SHIFTING IS ROUGH. I WILL BE TAKING IT TO A DEALER SOON..

  MITSUBISHI MOTORS WILL NOT ACCEPT LIABILITY AND PAY TO HAVE A FAILURE OF A FACTORY WELD REPAIRED ON THE RIGHT FRONT ENGINE CROSS MEMBER OF MY 2003 MITSUBISHI MONTERO WHICH IS STILL UNDER THE FACTORY WARRANTY. MY INSURANCE ADJUSTER HAS SUBMITTED A LETTER INFORMING MITSUBISHI'S VEHICLE DEPARTMENT THAT THE DAMAGE TO MY VEHICLE IS DUE TO FAILURE FROM IMPROPER WELDING. I HAVE ALSO BEEN INFORMED BY A CERTIFIED BODY SHOP THAT THE PART WAS NOT WELDED PROPERLY. MITSUBISHI HAS REFUSED TO PARTICIPATE IN REPAIRING THE VEHICLE SINCE AUGUST 12, 2005. *JB

• 09/03/2008· ENGINE AND ENGINE COOLING,POWER TRAIN

  I OWN A 2003 MITSUBISHI DIAMANTE, AROUND 60K MILES I STARTED NOTICING A SWEET SMELL FROM THE VENTS AND A CONSTANT FOG WHEN THE HEAT OR AIR WAS TURNED ON IN THE CAR. AFTER TAKING MY CAR TO THE MECHANIC I WAS TOLD THAT MY HEATER CORE WAS BUSTED. MY CAR ALSO SDRIVING IN "SAFE MODE" MEANING I CAN ONLY RUN IN SECOND GEAR WHICH IS BURNING A TANK OF GAS EVERY THREE DAY, I LOVE 10 MILES FROM WORK. MY CAR FLASHED IN NEUTRAL WILL IN DRIVE. AFTER RESEARCHING MY PROBLEMS I'VE NOTICE WELL OVER 1000 POSTED VIA INTERNET FROM OTHER MITSUBISHI DIAMANTE OWNERS HAVING THE SAME ISSUE. ITS HARD TO BELIEVE THIS VEHICLE HAS NOT BE RECALLED. THERE ARE GREAT RISKS OF INHALING ANTI FREEZE WHICH IS SEEPING INTO THE CAR THROUGH THE FLOOR BOARDS AND VENTS. I HAVE AN ASTHMATIC CHILD WHO HAS BEEN DRIVING IN THE CAR UNTIL THE PROBLEM WAS BROUGHT TO MY ATTENTION. THIS LEAK MAY ALSO MAKE THE COMPUTER SYSTEM IN THE VEHICLE GO OUT. SOMETHING NEEDS TO BE DONE BEFORE AN ACCIDENT IS CAUSED OR A LIFE IS TAKEN. *TR

• 08/30/2004· SERVICE BRAKES, HYDRAULIC

  WHEN THE BRAKES WERE APPLIED, THE VEHICLE VIBRATED UNCONTROLLABLY. THE DRIVER WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE AND DROVE IT TO A REPAIR SHOP FOR INSPECTION. THE MECHANIC INFORMED THE CONSUMER THAT THE ROTORS AND PADS MAY NEED TO BE REPLACED. *JB THE CONSUMER FOUND NOTHING APPARENTLY WRONG BEFORE THE PARTS WERE DISCARDED. *SC *JB

• 08/25/2005· EQUIPMENT

  WHEN I APPLY THE BRAKES, THE CAR SHAKES AND JERKS UNCONTROLLABLY. I HAVE HAD WORK DONE ON THE ROTORS AS WELL AS THE BRAKES. I HAVE LESS THAN 20K MILES ON THE CAR. IT IS HIGHLY UNUSUAL TO HAVE 4 WARPED ROTORS WITHOUT SOME TYPE OF MANUFACTURING DEFECT.

• 08/23/2006· VISIBILITY

  2003 MITSUBISHI DIAMANTE LS 58,000 MILES. I NOTICED A 'MAPLE SYRUP' SMELL IN THE CABIN WHEN THE AIR CONDITIONER AND HEATER WERE RUNNING. I TOOK IT TO THE DEALERSHIP WHEN I BEGAN HAVING TRANSMISSION PROBLEMS AS WELL. NO TRANSMISSION PROBLEMS WERE FOUND, BUT THE DEALER ADVISED THAT THE HEATER CORE NEEDED TO BE REPLACED AT A COST OF OVER $1,000. THEY WILL NOT KNOW FOR SEVERAL DAYS IF THE LEAKY HEATER CORE HAS AFFECTED THE TRANSMISSION OR ENGINE CONTROLS. THE HEATER CORE WAS LEAKING POTENTIALLY TOXIC COOLANT INTO MY PASSENGER COMPARTMENT IN THE CAR. DEALER ADVISED ME THAT THEY EXPECT EVERY DIAMANTE FROM 1997-2003 WILL NEED THIS DUE TO A MANUFACTURER'S DEFECT. MITSUBISHI ALSO RELEASED A SERVICE BULLETIN TO ALL DEALERS REGARDING THIS PROBLEM. MITSUBISHI SHOULD BE FORCED TO RECALL THE VEHICLES, OTHERWISE AT LEAST ADVISE ALL OF THE OWNERS OF SAID VEHICLES THAT THE UNITS SHOULD BE REPLACED IN THE MAINTENANCE SCHEDULE. *JB

  MAKE : MITSUBISHI MODEL : DIAMANTE LS YEAR: 2003 JUST PURCHASED CAR FROM DEALER STATING CAR IN EXCELLENT MECHANICAL CONDITION. UPON DELIVERY OF CAR FROM TRANSPORTER, GOT IN THE CAR KNEW IMMEDIATELY THERE WAS FILM ON WINDOW AND COULD SMELL COOLANT IN THE AIR. TURNED CAR ON, STRONG SMELL OF COOLANT COMING THROUGH VENTS WITH COOLANT LEAKING ONTO PASSENGER FLOOR. TEXAS AUTO GROUP, THE SELLER, REFUSED TO ACCEPT RESPONSIBILITY DESPITE REPRESENTING CAR IN EXCELLENT MECHANICAL CONDITION. TOOK TO A MITSUBISHI REPAIR SERVICE AND HAD TO HAVE HEATER CORE REPLACED AT A COST OF $1167.92. THIS REPAIR SERVICE 40 MILES AWAY AND IT TOOK 7 DAYS TO COMPLETE. HAD TO HAVE CARPET AND CAR DETAILED TO GET RID OF COOLANT SMELL. RESEARCHED ON INTERNET AND FOUND OUT THIS IS A PROBLEM THAT HAS BEEN GOING ON SINCE 1998 WITH THESE HEATER CORES WITH MITSUBISHI VERY MUCH AWARE OF IT, AND OBVIOUSLY NOTHING HAS BEEN DONE TO CHANGE THIS PROBLEM. THIS CAR ONLY HAS 61145 MILES ON IT AND THERE IS NO EXCUSE FOR THIS IRRESPONSIBILITY OR COSTS TO THE CONSUMERS OF THESE CARS,INCLUDING PROPERTY DAMAGE AS WELL AS HEALTH RISKS TO THE CONSUMERS AS COOLANT IS TOXIC TO BREATH. MITSUBISHI SHOULD BE FORCED TO DO A RECALL AND REIMBURSE THEIR CUSTOMERS AS THEY HAVE KNOW OF THIS PROBLEM AND HAVE DONE NOTHING ABOUT IT. UPON RESEARCHING MORE, HAVE FOUND THAT SOME FOLKS HAVE HAD TO HAVE IT REPAIRED MORE THAN ONCE. THERE IS NOW STARTING TO SHOW COMPLAINTS OF THE 2003 MODELS. VERY UNHAPPY CONSUMER AND FEEL TAKEN ADVANTAGE OF AND HAVE NOW PAID MORE FOR THIS CAR THEN IT IS WORTH. HOPE THIS WILL HELP ANOTHER UNSUSPECTING CUSTOMER OF THE MITSUBISHI DIAMANTES. *NM

  FOR THE PAST TWO YEARS OUR CAR HAS HAD A VERY PUNGENT FOWL SMELLING ODOR WHEN THE AIR CONDITIONER OR HEATER IS ENGAGED THAT HAS GOTTEN PROGRESSIVELY WORSE. I TOOK THE CAR FOR REPAIRS PRIOR TO THE TERMINATION OF THE WARRANTY AND WAS TOLD (BY THE DEALERSHIP) THAT THEY DID NOT NOTICE A SMELL, AND THERE WAS NO PROBLEM. SIX MOTHS AGO THE CAR BEGAN TO RUN HOT AND I TOOK THE CAR TO OUR NEIGHBORHOOD MECHANIC. UNDER PRESSURE HE NOTICED A SMALL LEAK IN THE COOLANT PIPING AND REPLACED A SECTION OF PIPE ($150.00). I ASKED IF THIS COULD BE CAUSING THE ODOR (AS MENTIONED EARLIER AND HE STATED MAYBE, OR IT COULD BE THE HEATER CORE).WITHIN THE PAST TWO WEEKS THE 'CHECK ENGINE SOON' LIGHT HAS COME ON AND UPON CHECKING THE MESSAGE AND INSPECTION OF MY CAR I'VE BEEN TOLD THE HEATER CORE NEEDS TO BE REPLACED. MY NEIGHBORHOOD MECHANIC WAS AT A LOSS BECAUSE TOLD ME IT WAS VERY ODD FOR THE HEATER CORE TO FAIL SO EARLY IN A CAR. I'VE CHECKED THE INTERNET AND HAVE COME ACROSS HUNDREDS OF PEOPLE IN THE SAME SITUATION (WITH MITSUBISHI'S). I AM VERY UPSET WITH THE FACT THAT THE MITSUBISHI DEALER MAY HAVE LIED TO ME (WHEN THE CAR WAS UNDER WARRANTY). I ASKED FOR MULTIPLE ITEMS TO BE FIXED (UNDER WARRANTY) AND THEY REFUTED EVERY REQUEST. THE HEATER CORE WILL BE REPLACED WITHIN TWO WEEKS. *TR

A NEW HEATERCORE INSTALLED VERY COSTLY HAD TO DO WORK MYSELF BECAUSE WARRANTY EXPIRED. HAD TO SHAMPOO CARPETS AND BUY NEW FLOORMATS BECAUSE THE ANITFREEZE RUINED THEM. AFTER READING MANY COMPLAINTS YOU WOULD THINK THAT A RECALL WOULD BE MADE. JUST BECAUSE NO DEATHS THE CONSUMER SHOULD SUFFER. WHAT ABOUT THE MONEY THAT IT TOOK TO MAKE THE REPAIR.

DAYS LATER THE FRONT WINDSHIELD STARTED FOGGING UP WHILE DRIVING AND AFTER TURNING THE CAR OFF (WHETHER IT IS WARM OR COLD OUTSIDE) I GOOGLED WHY WOULD THIS HAPPEN AND HAVE SPOKEN WITH A FEW MECHANICS AND THEY ARE TELLING ME THAT IT IS THE HEATER CORE GOING OUT, AND THAT THE REASON WHY MY HUSBAND IS GETTING LIGHT HEADED AND NAUSEOUS IS BECAUSE THERE IS ANTI-FREEZE COMING INTO THE INTERIOR OF THE CAR WHICH IS VERY DETRIMENTAL TO YOUR HEALTH. I HAVE READ A TON OF COMPLAINTS ON DIFFERENT WEBSITES AND THEY ALL SAY THE SAME THING. I CONTACTED MITSUBISHI CORPORATE TODAY AND SPOKE WITH A [XXX] IN CUSTOMER SERVICE AND EXPLAINED TO HER WHAT WAS GOING ON AND ASKED WHY MITSUBISHI HAS NOT DONE ANYTHING ABOUT THIS. FIRST BECAUSE OF THE HEALTH IMPLICATIONS, SECONDLY BECAUSE OF THE SAFETY ISSUE OF THE WINDSHIELD FOGGING UP WHILE YOU'RE DRIVING TO WHERE YOU CAN'T SEE AND THIRDLY THAT FROM READING THE COMPLAINTS, THE HEATER CORE IS RIGHT ABOVE THE COMPUTER IN THE CAR SO IF THE HEATER CORE IS LEAKING ANTIFREEZE, IT COULD FRY THE COMPUTER AND CAUSE A POSSIBLE CRASH IF THE CAR WERE TO STOP SUDDENLY. SHE SAID THAT "SEEING THAT I HADN'T HAD THE CAR INTO A DEALERSHIP IN THE LAST YEAR THAT THERE IS NOTHING THEY CAN DO ABOUT IT". I TOLD HER THAT IT JUST STARTED AND WHAT WAS I SUPPOSE TO DO, LOOK INTO MY CRYSTAL BALL AND KNOW A YEAR AHEAD OF TIME THAT THE HEATER CORE WAS GOING TO GO OUT. THIS IS LUDICROUS! ! ! MITSUBISHI KNOWS THAT THIS IS A SERIOUS ISSUE AND ARE NOT DOING ONE THING TO FIX IT (BY ISSUING A RECALL) WHERE DO WE DIAMANTE OWNERS GO TO GET SOME HELP? DO WE NEED TO FILE A CLASS ACTION LAWSUIT AS THAT SEEMS LIKE THE ONLY WAY A FIRE IS GOING TO GET LIT UNDER THEM (CORPORATIONS TEND TO ACT IF IT MEANS LOSING TONS OF MONEY) THE CAR CAN'T BE DRIVEN AND I'M STILL PAYING ON IT.

  I OWN A 2003 DIAMANTE MITSUBISHI. THE PROBLEM STARTED WITH A CHECK ENGINE LIGHT COMING ON, FOGGING THE WINDOW WITH A FOWL TOXIC SMELL THEN THE CAR WOULD NOT HARDLY MOVE OUT GEAR. I WAS TOLD THAT THE CAR'S HEATER CORE LEAKED ONTO THE COMPUTER WHICH CAUSED THE TRANSMISSION RELAY TO SHORT OUT DO TO THE COMPUTER FAILING. THE COMPUTER WAS STILL UNDER WARRANTY AT 78,000 MILES BUT I STILL HAD TO PAY FOR THE NEW COMPUTER SYSTEM BECAUSE I WAS TOLD THAT IT WAS THE HEATER CORE THAT CAUSED THE COMPUTER TO FAIL. THIS IS SUCH A POOR DESIGN! THE COMPUTER SHOULD HAVE BEEN PROTECTED IN SUCH A CASE...FUNNY THING IT IS NOW THAT I HAVE HAD TO REPLACE A HEATER CORE, A COMPUTER AND A TRANSMISSION RELAY AT A CUT WRENCHING COST OF $3,675.58. I WROTE A LETTER TO THE PRESIDENT OF NORTH AMERICA MITSUBISHI THAT THE HEATER CORE SHOULD BE A RECALL BUT TO NO AVAIL. I HAVE ALL MAINTENANCE RECORDS ON THE DIAMANTE SO THAT WAS NOT WHAT CAUSED THIS HEATER FAILURE. I DO HAVE THE COMPUTER THAT WAS REPLACED. IT IS NOW APRIL AND THE CHECK ENGINE LIGHT HAS COME BACK ON...NOW WHAT? AJ *TR

  STEERING WHEEL BEGAN TO SHAKE AND VISIBLE FUMES BEGAN ENTERING VEHICLE THROUGH AIR VENTS. THERE WAS A STRONG STENCH OF ANTI-FREEZE. CHECK ENGINE LIGHT WAS ON AND VEHICLE BECAME HARD TO CONTROL. AFTER TAKING CAR TO LOCAL DEALERSHIP, I WAS IMMEDIATELY TOLD, EVEN BEFORE AN INSPECTION WAS DONE, THAT THE HEATER CORE ON VEHICLE HAD A SLOW LEAK THAT OVER THE COURSE OF "SEVERAL MONTHS" THAT EVENTUALLY LEAKED ON TO THE TRANSMISSION ELECTRIC BOX AND SHORTED OUT THE ENTIRE SYSTEM. IT SEEMED OBVIOUS THAT THIS WAS A FAMILIAR ISSUE WITH THIS PARTICULAR VEHICLE. I WAS ORIGINALLY GIVEN AN ESTIMATE OF $3,300, BEING THAT THE VEHICLE WAS PAST ITS WARRANTY PERIOD. AFTER SEVERAL CALLS TO OWNER OF DEALERSHIP AND DOING RESEARCH ON THIS VEHICLES COMPLAINT HISTORY, THE PRICE WAS REDUCED 3 SEPARATE TIMES, FINALLY COSTING ME $880. APPARENTLY, MITSUBISHI HEADQUARTERS PICKED UP THE COST OF THE PARTS, LEAVING ME TO PAY LABOR CHARGES. THE MECHANIC HANDLING THE REPAIR STATED THAT DUE TO "POOR DESIGN" ON THIS PARTICULAR VEHICLE, AND EVEN WITH OUR REGULAR MAINTENANCE CHECKS AT THE DEALERSHIP, THIS PROBLEM CANNOT POSSIBLY BE RECOGNIZED OR DIAGNOSED IN ITS EARLY STAGES UNTIL IT HAS CAUSED EXTENSIVE DAMAGE. NEEDLESS TO SAY, THIS WILL BE MY LAST MITSUBUSHI. *JB
