I TOOK MY 2001 CHEVY MALIBU LS IN TO GET THE OIL CHANGED. THE MECHANIC TOLD ME THAT A COMMON PROBLEM FOR THE GM ENGINES OF MY YEAR AND OTHERS WAS THE INTAKE MANIFOLD GASKET LEAKING COOLANT, AND THAT IF LEFT UN-FIXED, THE ENGINE WOULD EVENTUALLY SEIZE UP. I WAS TOLD THAT THE MATERIAL THAT THE GASKETS WERE MADE OUT OF HAS SINCE BEEN CHANGED, WHICH WOULD IMPLY THAT THEY KNOW IT TO BE FAULTY. I CONTACTED GM AND TOOK IT INTO THE DEALER WHERE THEY CONFIRMED THE PROBLEM. I DON'T KNOW IF THIS ISSUE MAKES THE CAR UNSAFE TO DRIVE, BUT I HAD HEARD THAT THERE WAS A RECALL IN PLACE FOR FAULTY ALTERNATORS AND FIGURED THIS PROBLEM WAS ABOUT EQUAL TO THAT IN POTENTIAL DANGER. OUT OF CURIOSITY, I LOOKED ON THE INTERNET AND THERE ARE PLENTY OF WEBSITES WITH PEOPLE THAT HAVE THE SAME ISSUE. *JB

THE VEHICLES HEAT GAUGE STOPPED WORKING AND LOW COOLANT LIGHT CAME ON. CHECKED COOLANT LEVEL AND DISCOVERED SLUDGE IN EXPANSION CHAMBER ( COOLANT RECOVERY TANK). FLUSHED SYSTEM OF SLUDGE AND TROUBLE SHOT REASON FOR COOLANT LOSS. FOUND INTAKE MANIFOLD GASKET LEAKING. VEHICLE WILL REQUIRE NEW INTAKE MANIFOLD GASKET SET, THERMOSTAT, HOSES, WATER PUMP AND POSSIBLY RADIATOR. TRIED TO FLUSH SYSTEM COMPLETELY BUT FOUND SECONDARY PLUMBING SUCH AS HEATER CORE, RADIATOR,COOLANT CROSSOVER AND COOLANT BLEED HOSING GUMMED UP WITH OILY WAXY TYPE SUBSTANCE RESEMBLING GUMBALLS (DEX-COOL?). I THINK GM SHOULD STEP UP TO THE PLATE AND TAKE RESPONSIBILITY FOR THE SO CALLED "WONDER COOLANT". AFTER ALL THE STICKER ON THE EXPANSION CHAMBER DOES SAY ANYTHING ABOUT CHANGING EVERY 5 YEARS OR 150000 MILES. *JB

(1) COOLANT LEAKING IMMEDIATELY AFTER PUTTING IT INTO MY VEHICLE. (2) MY CAR HAS OVERHEATED THREE TIMES ON THE FREEWAY. IT WILL NOT ACCELERATE, STARTS VIOLENTLY VIBRATING, THEN SMOKE BELLOWS OUT OF MY HOOD WHEN I FINALLY STOP. I HAVE BEEN STRANDED ON THE FREEWAY THREE TIMES WITH MY TWO-YEAR-OLD IN THE CAR, AS WELL AS MY UNBORN CHILD. (3) I HAVE TAKEN MY VEHICLE TO A CHEVROLET REPAIR MAN WHO FOUND A TECHNICAL SERVICE BULLETIN ON THE PROBLEM ISSUED BY CHEVROLET. HE EXPLAINED THE INTAKE MANIFOLD WAS MANUFACTURED CROOKED CAUSING COOLANT TO LEAK INTO MY ENGINE AND DILUTE MY OIL WHICH WILL EVENTUALLY BURN MY MOTOR AND RUIN IT COMPLETELY. WHEN I CONTACTED CHEVROLET, THEY WERE VERY UNHELPFUL BOTH TIMES STATING I HAD TO PAY A CHEVY DEALERSHIP TO DIAGNOSE THE PROBLEM AND THAT THEY MIGHT HELP ME WITH A LITTLE COST ASSISTANCE BUT NOT MUCH. IT IS ABOUT $600 TO FIX THIS PROBLEM THAT IS NOT NORMAL MAINTENANCE OR WEAR-AND-TEAR. IT IS A MANUFACTURING DEFECT. I HAVE HAD SEVERAL PEOPLE E-MAIL ME ABOUT THE SAME PROBLEM AFTER POSTING A COMMENT ABOUT IT ON A WEBSITE. *NM

Official recalls
2Jul 3, 2014
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 3, 2014, that they are recalling 5,877,718 model year 2000-2005 Chevrolet Impala and Monte Carlo, 1997-2003 Chevrolet Malibu, 2004-2005 Malibu Classic, 1999-2004 Oldsmobile Alero, 1998-2002 Oldsmobile Intrigue, 1999-2005 Pontiac Grand Am and 2004-2008 Pontiac Grand Prix vehicles. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence & remedy
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 9, 2014. GM's number for this recall is 14350.
Aug 28, 2003
CERTAIN PASSENGER VEHICLES HAVE HAZARD WARNING SWITCHES THAT MAY EXPERIENCE SOLDER JOINT CRACKING CAUSED BY RAPID TEMPERATURE TRANSITIONS AND THE SOLDERING PROCESS. IF SOLDER JOINT CRACKING OCCURS AND RESULTS IN AN OPEN CIRCUIT, THE TURN SIGNALS/HAZARD LAMPS BECOME INTERMITTENT OR INOPERATIVE.
Consequence & remedy
Consequence: WHEN THE TURN SIGNALS ARE INOPERATIVE, THE DRIVER CANNOT USE THEM TO SIGNAL INTENT TO TURN THAT COULD RESULT IN A CRASH.
Remedy: DEALERS WILL REPLACE THE HAZARD WARNING SWITCH. OWNER NOTIFICATION BEGAN ON FEBRUARY 5, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, PONTIAC AT 1-800-620-7668, OR OLDSMOBILE AT 1-800-630-6537.
