2003 Mitsubishi Diamante

VARIOUS INTERMITTENT FAILURES TO INCLUDE, CAR LOCKING ON ITS OWN, HEADLIGHTS NOT GOING OUT WHEN CAR IS TURNED OFF, CAR NOT DINGING WHEN KEYS LEFT IN IGNITION, AND WINDOW FUSE BEING BLOWN WHEN WINDOWS ARE NOT BEING RAISED OR LOWERED. HAVE TAKEN CAR TO DEALER AND AN ELECTRICAL SPECIALIST. BOTH HAVE SAID THEY CAN'T FIX IT SINCE THE PROBLEM IS INTERMITTENT. *NM

I NOTICED THAT THE WINDSHIELD WAS FOGGED, AND THE DEFROSTER WOULD NOT CLEAR THE FOG. BLAMED IT ON THE HUMID FLORIDA WEATHER UNTIL ONE EVENING I WAS DRIVING HOME FROM WORK AND ALL OF MY WINDOWS WERE FOGGED. HAD TO KEEP WIPING THE WINDOWS WITH MY HAND IN ORDER TO SEE OUT THE WINDOW. TOOK THE CAR TO TO BE CHECKED, AND IT WAS THE HEATER CORE. THIS CAR IS TOO NEW FOR THE HEATER CORE TO HAVE GONE BAD. *NM

HEATER CORE ISSUE WITH MITSUBISHI DIAMANTE 2003 SUMMARY: NOTICE CONSISTENT AND VERY NOTICEABLE FOUL ODOR WHEN HEATER IS ON. . FOGGING OF FRONT WINDSHIELD. HAVE HAD THIS PROBLEM IDENTIFIED AS CONSISTENT WITH HEATER CORES ISSUES BY OTHER DIAMANTE OWNERS WHO HAVE HAD THEIR CAR SERVICED AT A MITSUBISHI DEALER. HAVE NOT REPLACED ANYTHING YET BECAUSE THE PARTS AND LABOR QUOTES HAVE BEEN ANYWHERE FROM $600-$1000. CAR HAS 36,000 MILES ON IT. *NM

ON FRIDAY, JAN 19, 2007, I WENT TO MY 2003 MITSUBISHI DIAMANTE VRX AFTER WORK TO GO HOME. WHEN I GOT TO IT, ALL WINDOWS WERE TOTALLY FOGGED OVER, WHICH IS ABNORMAL. WITH HIGH HEAT, I WAS ABLE TO CLEAR A PORTION OF THE WINDSHIELD, RELYING ON A PAPER TOWEL TO CLEAR THE REMAINDER. I PARKED THE VEHICLE FOR ABOUT 2 HOURS AFTER ARRIVING AT HOME AND HAD TO RELY ON PAPER TOWELS TO CLEAR THE WINDSHIELD ONCE AGAIN. THIS TIME, I NOTICED A DISTINCT ANTIFREEZE SMELL. THE FOLLOWING DAY, THE SUNLIGHT SHOWED THE FILM TO BE OF A GREEN COLOR. AT THIS TIME, I REALIZED THAT THE WINDOWS WEREN'T FOGGY, BUT IT SEEMED THAT ANTIFREEZE VAPORS WERE BLOWING INTO MY CAR. AFTER SOME RESEARCH ON THE DIAMANTE OWNERS' GROUP WEBSITE, IT WAS EVIDENT THAT THE HEATER CORE OR O-RINGS WERE CAUSING THIS. I TOOK THE VEHICLE TO LAWSON MITSUBISHI, WHERE IT IS BEING REPAIRED. THIS IS SOMETHING THAT HAPPENED WITH LITTLE IDENTIFIABLE WARNING. HAD THIS HAPPENED ON THE ROAD, AN ACCIDENT WOULD HAVE SURELY ENSUED. *NM

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

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

I OWN A 2003 MITSUBISHI DIAMANTE VRX AND HAVE A BAD HEATER CORE AT 43,000 MILES. I HAVE READ ON THIS WEBSITE HTTP://WWW.DIAMANTEOWNERS.COM/FORUM/INDEX.PHP?SHOWTOPIC=3615&ST=60 THAT THE HEATER CORE IS LOCATED DIRECTLY ABOVE THE CAR'S COMPUTER. THIS IS EXTREMELY DANGEROUS AS LEAKING FLUIDS ONTO THE COMPUTER CAN CAUSE THE CAR TO MALFUNCTION AND CAUSE AN ACCIDENT. PERHAPS THIS SHOULD BE A RECALL? *JB

CAR SHAKES WHEN BRAKES ARE APPLIED. HAD BRAKES & ROTORS REPLACED AT 50,000 MILES. MECHANIC SAID ROTORS WERE TOO DAMAGED TO TURN. AFTER 6 MONTHS AND 20,000 MILES, THE CAR IS SHAKING AGAIN WHEN BRAKING. TOOK BACK TO MECHANIC, WHO CHECKED THE ROTORS AND SAID THEY NEED TO BE TURNED. I OWN A 1998 MITSUBISHI DIAMANTE, AND THAT CAR DOES NOT NEED THE ROTORS REPLACED EVERY TIME I REPLACE THE BRAKE PADS. MY DRIVING IS MOSTLY HIGHWAY, SO I DON'T USE THESE BRAKES MUCH. *JB
