IN EARLY 2005, I STARTED NOTICING THAT MY WINDOWS WERE FOGGING FOR NO REASON WHILE DRIVING AND IT WAS HARD TO DEFROST THEM. A DEFINITE SAFETY HAZARD, BECAUSE I COULD NOT SEE THAT WELL. LATER, I STARTED NOTICING A WEIRD SMELL IN THE CABIN. (IT TURNED OUT TO BE COOLANT; IT CAN'T BE GOOD FOR YOUR HEALTH) IN MID 2005, I SAW FOG/SMOKE COMING FROM THE VENTS. A REPAIR SHOP CONFIRMED THAT IT WAS A PROBLEM WITH THE HEATER CORE, AND IT WOULD BE AT LEAST $800 TO FIX. THE DEALER TOLD ME THAT MY CAR IS OUT OF WARRANTY. I PURCHASED THE VEHICLE IN DECEMBER 2001, AND IT NOW HAS ONLY 30600 MILES. *NM

COMPLAINT RECEIVED VIA E-MAIL. THE HEATER CORE HAD TO BE REPLACED BECAUSE OF LEAKING ANTIFREEZE INTO THE PASSENGER COMPARTMENT AND FOGGING OF WINDSHIELD. WHEN I TOOK MY VEHICLE IN I WAS ADVISED AT THAT TIME THERE WAS ANOTHER DIAMANTE (2002) THAT REQUIRED A HEATER CORE, AND THE VEHICLE AT APPROXIMATELY 42,000 MILES. WHEN THE HEATER CORE WAS BEING REMOVED I NOTICED IT FAILED TO HAVE SUFFICIENT INSULATION AS THIS COULD CAUSE FAILURE BY VIBRATION OVER NORMAL ROADS.*AK
