NHTSA Complaint #10078909 — 1999 PONTIAC GRAND AM

SECOND NOTICE POSTED: INCE 2002: REPLACED ROTORS, TOO THIN WHEN CAR WAS MANUFACTURED. (NO RECALL EVER DONE). COOLING SYSTEM: ALTHOUGH THE MANIFOLD GASKET HAS BEEN REPLACED, THE WATER RESERVOIR CAP HAS BEEN REPLACED, THE RADIATOR FLUSHED REPEATEDLY, ENTIRE COOLING SYSTEM BLEED (TO REMOVE ANY EXCESS AIR FROM RADIATOR), SERPENTINE BELT REPLACED, ALL FUSES, INCLUDING THE AC RELAY FUSE/SWITCH, ALL SENSORS REPLACED, AND VARIOUS MECHANICS HAVE CHECKED THE ENTIRE CAR BUMPER-TO-BUMPER, IT CONTINUES TO LEAK ANTIFREEZE COOLANT BY FORCING THE WATER OUT OF THE RADIATOR INTO THE RESERVOIR AND OUT THROUGH THE OVERFLOW TUB (SMALL TUBE LOCATED ON RESERVOIR TANK). EXCESS PRESSURE BUILDING UP IN THE SYSTEM. LEAKING ANTIFREEZE ONCE CAR IS STOPPED. I HAVE TO REFILL THE TANK AT LEAST ONCE A WEEK. THIS PROBLEM (THE PONTIAC GRAND AM LEAKING COOLANT) IS A COMMON PROBLEM WITH ALL PONTIAC GRAND AM. RECALL TO SOME COMPONENT OF COOLING SYSTEM IS DIRE OVERDUE! THIS CAR IS AN OIL CHANGE EVERY THREE MONTHS, REGARDLESS OF 3000 MILES OR NOT, STILL OUT OF THE BLUE, THE LIFTERS ARE KNOCKING AND THE BELT IS MAKING A VERY HIGH PITCHED SCREECHING SOUND. BELIEVED TENSION PULLEY NEEDS REPLACING, WITH A POSSIBILITY THAT ALL OTHER PULLEYS NEED REPLACING. ITS NOT THE BELT; THE BELT HAS BEEN CONSIDERED BY THREE DIFFERENT MECHANICS HAS BEEN "BASICALLY NEW". ALSO, ALTHOUGH IT HAS ONLY HAPPENED THREE TIMES IN THE LAST SEVERAL MONTHS, THE ENGINE HAS STALLED. WHEN THIS ORIGINALLY HAPPENED I CHANGED THE GRADE OF GASOLINE I PUT IN THE CAR FROM 87 GRADE TO 89 GRADE. DIDN'T HELP. (NUMBER OF FAILURES: FOR COOLANT LEAKS: INFINITE). *AK
