NHTSA Complaint #10550500 — 2004 CHEVROLET IMPALA

(1) HEATING SYSTEM FAILED. NO HEAT, COOLANT WAS OK. FAN WAS RUNNING. DEALER EXAMINED. THREE ACTUATORS IN THE ELECTRONICS ARE FAILED AND HAVE TO REPLACE AT A COST OF OVER $550.00 (2) TEMPERATURE GAUGE STOPPED MOVING. DEALER EXAMINED. ESTIMATED COST OF $~400.00 TO REPLACE IPC UNIT. THERE IS ONE OF THE RECALLED IPC UNITS FOR GM AUTOS MADE BETWEEN 2003-2007; BUT IMPALA WAS NOT INCLUDED IN THE RECALL LIST. I DON'T KNOW WHY? SAME ELECTRONICS FAILED IN ONE UNIT MUST BE RECALLED FROM ALL THE UNITS.. THESE DEFECTS COULD INCREASE HEAT IN THE ENGINE BLOCK AND COULD INCREASE FUEL CONSUMPTION, FAILURE OF THE ENGINE AND POSSIBLY CAUSE FIRE, CONTACTED GM BUT THEY WERE NOT COOPERATIVE AND DENIED ANY CLAIMS. *TR
