ODI #10324254

Incident: January 1, 2010 · Filed: April 6, 2010

2000 MITSUBISHI DIAMANTE. CONSUMER STATES VEHICLE SURGED FORWARD. *TGW THE CONSUMER STATED WHEN LEAVING A PARKING LOT AND ATTEMPTING TO PULL INTO TRAFFIC, THE VEHICLE BARELY MOVED AT 5 MPH, EVEN THOUGH HE WAS PRESSING ON THE ACCELERATOR AND THE RPM WAS NOT MOVING. AFTER GOING ABOUT 1/4 OF A MILE, ALL OF A SUDDEN THE VEHICLE JUMPED INTO GEAR AND THE VEHICLE LURCHED FORWARD. THE NEXT DAY, A REPRESENTATIVE FROM MITSUBISHI WENT TO THE CONSUMER'S WORKPLACE AND EXAMINED THE VEHICLE. THE REPRESENTATIVE STATED THE THROTTLE CABLE NEEDED TO BE ADJUSTED AND SUGGESTED THE CONSUMER TAKE THE VEHICLE TO THE DEALER. THE CONSUMER STATED THE DEALER NEVER RECEIVED ANY INFORMATION TO ORDER A NEW CABLE AND THE HIS VEHICLE STILL HAS NOT BEEN FIXED. *JB

Incident: June 28, 2005 · Filed: February 10, 2010

WHEN I FIRST START THE CAR, DRIVE ABOUT A HALF BLOCK, OBTAIN DESIRED SPEED, TAKE MY FOOT OFF THE ACCELERATOR, AND THEN WHEN THE CAR SLOWS DOWN, I PRESS DOWN ON THE ACCELERATOR, NOTHING HAPPENS. SO I PRESS DOWN FURTHER ON THE GAS PEDAL, AND SUDDENLY THE CAR LURCHES FORWARD OUT OF CONTROL. SO THEN I HAVE TO IMMEDIATELY TAKE MY FOOT OFF THE GAS PEDAL AND BRAKE SLIGHTLY UNTIL THE CAR GOES THE RIGHT SPEED. THIS HAS HAPPENED ONLY WHEN THE CAR WAS COLD AND ONLY INTERMITTENTLY, ABOUT SEVEN TIMES IN THE LAST 10 YEARS. MY MECHANIC SUPPOSEDLY FIXED IT, BUT THE ACCELERATOR GOT STUCK AGAIN AFTER THE ALLEGED REPAIR. THERE WERE NO CONSEQUENCES EXCEPT FOR A NAGGING FEAR IN THE BACK OF MY MIND FOR THE LAST 10 YEARS. ANOTHER INTERMITTENT PROBLEM IS THAT THE LIGHTS FOR TCL AND FIX ENGINE SOON WILL COME ON WHILE I AM DRIVING, GO OFF WHEN I TURN OFF THE CAR, AND THEN STAY OFF FOR SEVERAL CAR TRIPS AND ONE OR THE OTHER LIGHT WILL COME ON AGAIN INTERMITTENTLY. *TR

Incident: November 12, 2007 · Filed: November 13, 2007

FOR OVER 2 YEARS NOW I HAVE HAD PROBLEMS WITH AN ODOR IN MY 2000 DIAMANTI AND THE DEFOGGER NEVER SEEMED TO WORK ON THE WINDOWS. A COUPLE OF WEEKS AGO I SAW SOMETHING LEAK ONTO THE PASSENGER SIDE RUG BUT DIDN'T' T GUESS THAT THIS COULD HAVE SOMETHING TO DO WITH THE HEATER CORE. UPON TAKING IT TO MY DEALER I WAS TOLD THIS WAS HOLE IN THE HEATER CORE THAT HAD TO BE FIXED IMMEDIATELY BECAUSE IT WAS DANGEROUS AND HAZARDOUS TO MY HEALTH TO BREATH THE FUMES THAT WERE COMING OUT OF THE CORE. THE COST WOULD BE APPROXIMATELY $1200. I NOTICED I OFTEN HAD HEADACHES WHEN I DROVE LONG DISTANCES BUT WAS VERY CONCERNED WHEN MY GRANDCHILD BECAME VERY CAR SICK (WHICH HAD NEVER HAPPENED BEFORE) UPON RIDING IN MY CAR. I STILL DIDN'T ASSOCIATE THE HEATER WITH OUR PROBLEMS. I THINK THIS IS VERY DANGEROUS AND SOMETHING SHOULD BE RECALLED ON THESE. I RESENT THAT AFTER ONLY 40,000 MILES I MUST SPEND $1200 ON SOMETHING THAT IS OBVIOUSLY A MISTAKE ON MITSUBISHI'S PART SINCE IT IS NOT A WEAR FACTOR. *TR

Incident: October 12, 2005 · Filed: October 15, 2005

I CURRENTLY HAVE WHAT IS DESCRIBED TO BE A "HEATER CORE FAILURE" IN MY 2000 MITSUBISHI DIAMANTE. I HAVE BEEN MADE AWARE THAT THIS ISSUE IS FAIRLY COMMON AMONGST DIAMANTES. ANY TIME I TURN ON THE HEATER, MY AUTOMOBILE IS FILLED WITH A NOXIOUS ODOR THAT I'M LEAD TO BELIEVE MIGHT BE DETRIMENTAL TO MY HEALTH. I AM ALSO UNABLE TO DEFROST MY WINDOWS BECAUSE OF THIS PROBLEM. THIS CAUSES A DANGEROUS DRIVING CONDITION AS I'M FORCED TO CONSTANTLY WIPE THE WINDSHIELD WITH A PAPER TOWEL.*JB

Incident: October 5, 2005 · Filed: October 11, 2005

VEHICLE CHECK ENGINE LIGHT CAME ON AND LOCKED INTO THIRD GEAR. NOTICED SMELL OF COOLANT INSIDE DRIVERS COMPARTMENT AND HAZING OF THE WINDSHIELD. BROUGHT VEHICLE TO DEALER TO HAVE PROBLEM IMPROPERLY DIAGNOSED AND HAD TO HAVE IT RE-TESTED TWO WEEKS LATER. HEATER CORE LEAKAGE HAS CAUSED DAMAGE TO THE ECU AND NOW BOTH HAVE TO BE REPLACED. TOTAL COST OF REPAIR FOR BOTH WAS $3,357.62. COOLANT FUMES ARE VERY TOXIC AND CAUSE A SIGNIFICANT HEALTH RISK AND ECU FAILURE COULD EASILY RESULT IN A VERY SERIOUS ACCIDENT ON THE HIGHWAY OR ELSEWHERE. THE "FOGGING" OF THE WINDSHIELD IS A VISIBILITY HAZARD AS WELL CAUSED BY THE HOT COOLANT IN THE DEFROST VENTS. *JB

ODI #10135134

Incident: August 24, 2005 · Filed: September 1, 2005

THE HEATER CORE HAS FAILED FOR THE SECOND TIME. I PURCHASED THE CAR FROM A DEALER WITH 54,000 MILES ON IT AND AFTER 500 MILES THE HEATERCORE IS FRIED. THE WORST PART IS THAT WHEN I WENT TO THE MITSUBISHI DEALERSHIP TO GET MY REMOTE REPROGRAMMED I GOT THE PRINTOUT OF ALL THE PREVIOUS SERVICE THAT WAS DONE ON IT. THE HEATER CORE WAS ALREADY REPLACED AT 24,000 MILES!!! DOES THIS MEAN THAT I WILL HAVE TO SPEND AROUND $1,000 EVERY 25K MILES THAT I DRIVE THE CAR??? MITSUBISHI, PLEASE ADDRESS THIS PROBLEM! REGARDING TO THE PROBLEM ITSELF... I GOT ALL THE USUAL SYMPTOMS - THE WINDSHIELD WAS FOGGING UP, THERE WAS A STRONG SMELL OF THE ANTIFREEZE IN THE CAR AND NOW THERE'S A POOL OF ANTIFREEZE BY THE PASSENGER'S SEAT. THIS CANNOT BE GOOD FOR MY RESPIRATORY SYSTEM... ANTIFREEZE IS A POISON. I'VE HAD SOME PROBLEMS WITH MY LUNGS BEFORE AND IF IT GETS WORSE AFTER THIS PROBLEM, MITSUBISHI WILL LOOK AT A HUGE LAWSUIT. *NM
