I HAVE A 2003 MITSUBISHI DIAMANTE LS WITH 71677 MILES ON IT ALL OF THE SUDDEN MY HUSBAND (THE PRIMARY DRIVER) TELLS ME THAT EVERY TIME HE GETS OUT OF THE CAR HE FEELS LIGHT HEADED AND NAUSEOUS. 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.

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). THIS CONCERNS MY 2003 MITSUBISHI DIAMANTE. IT HAS LESS THAN 50,000 MILES ON IT AND IT HAS SUDDENLY STARTED SPEWING A LIGHT FILM ON THE INSIDE OF MY FRONT WINDSHIELD SO THAT I CANNOT SEE WELL...AND NOT AT ALL WHEN I AM HEADED INTO THE SUN. I HAVE CHECKED ON THE INTERNET AND A LOT OF PEOPLE ARE HAVING THE SAME PROBLEM WITH MITSUBISHI DIAMANTES GOING BACK SEVERAL MODEL YEARS. ALL DIAMANTES NEED TO BE RECALLED AND THE HEATER CORE AND/OR ITS O RINGS FIXED OR REPLACED. IF THIS DOESN'T HAPPEN, PEOPLE WILL DIE WHEN THEY SUDDENLY CANNOT SEE THE ROAD THROUGH THEIR FRONT WINDSHIELD. [XXX] *TR *DT

I HAVE A 2003 MITSUBISHI DIAMANTE WITH 60,000 PLUS MILES. FOR THE PAST SEVERAL MONTHS I HAVE NOTICED A STRONG SMELL OF ANTI-FREEZE COMING FROM THE VENTS AND THE WINDOWS CONSTANTLY FOGGING UP, SOMETIMES TO THE POINT THAT I CANNOT SEE TO DRIVE. I HAVE READ MANY SIMILAR COMPLAINTS AND AGREE WITH OTHERS THAT MITSUBISHI NEEDS TO ISSUE A RECALL FOR THE HEATER CORE, AS I AM SURE THIS IS THE PROBLEM. I HAVE YET TO TAKE MINE IN TO GET IT REPAIRED, SO I DON'T HAVE A COST QUOTE AT THIS TIME. *TR
