2002 CHEVY IMPALA 3.4L 84,000+ MILES LOW COOLANT LIGHT COMES ON. LEAKING ANTIFREEZE BUT NOT SURE WHERE. CONTINUALLY HAVING TO ADD ANTIFREEZE TO OVERFLOW TO MAINTAIN LEVEL. CAR SMELLS LIKE BURNING ANTIFREEZE AFTER BEING DRIVEN. NUMEROUS COMPLAINTS FOUND ONLINE AT CAR FORUMS WITH OTHER CONSUMERS HAVING THE SAME TROUBLE.

ONE THEORY IS DEXCOOL CAUSES THE SLUDGE. ANOTHER THEORY IS FAULTY INTAKE VALVE & GASKET. MAIN THEORY IS PROBLEM ORIGINATES FROM INTAKE VALVE (GASKET) AND DOMINOS. *TR

AT ABOUT 100,000 MILES THE CAR OVERHEATED. WE TOOK IT TO THE DEALER AND THEY SAID IT NEEDED NEW HEAD GASKETS AT A COST $1300.00 POSSIBLY HIGHER IF THE HEADS ARE DAMAGED. THIS IS A VERY COMMON PROBLEM WITH GM VEHICLES YET GM REFUSES TO ACKNOWLEDGE THAT IT A DEFECT IN THEIR PRODUCT. WE HAVE PURCHASED A FORD CAR AND WILL NEVER PURCHASE A GM PRODUCT AGAIN.

I HAVE TWICE HAD TO TAKE MY 2002 CHEVROLET IMPALA TO THE SHOP (RESULTING IN LOST TIME FROM WORK AND UNNECESSARY REPAIR BILLS) BECAUSE THE LOW ENGINE COOLANT WARNING LIGHT COMES ON AND STAYS ON EVEN THOUGH THE COOLANT LEVEL IS FULL. THE REPAIR SHOP HAS TWICE FOUND OIL IN THE COOLANT, DESPITE HAVING FLUSHED THE COOLING SYSTEM AND INSTALLING A NEW LOW COOLANT LEVEL SENSOR AT A COST OF $165. NOW I AM TOLD THAT THIS IS A COMMON PROBLEM WITH THE INTAKE MANIFOLD GASKET ON THIS TYPE OF VEHICLE AND THAT IT WILL COST AROUND $900 TO FIX IT PROPERLY. THIS CAR HAD ONLY 20,580 MILES ON IT WHEN THE PROBLEM WAS FIRST ATTENDED TO AND NOW STILL HAS ONLY 21,557 MILES. *JB

Official recalls
4Oct 26, 2015
General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
Consequence & remedy
Consequence: Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Remedy: The remedy applied under recalls 08V-118, 09V-116, and 15V-201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engines front valve cover and gasket. Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number. The recall began on February 19, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020, Buick customer service at 1-800-521-7300, Oldsmobile customer service at 1-800-442-6537 and Pontiac customer service at 1-800-458-8006. GM's number for this recall is 15757. Note: Until the improved remedy has been applied, owners are advised to park their vehicle outside since the fire risk exists even when the vehicle is unattended.

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.

SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH DROPS OF ENGINE OIL MAY BE DEPOSITED ON THE EXHAUST MANIFOLD THROUGH HARD BRAKING.
Consequence & remedy
Consequence: IF THE MANIFOLD IS HOT ENOUGH AND THE OIL RUNS BELOW THE HEAT SHIELD, IT MAY IGNITE INTO A SMALL FLAME AND MAY SPREAD TO THE PLASTIC SPARK PLUG WIRE CHANNEL AND BEYOND INCREASING THE RISK OF AN ENGINE COMPARTMENT FIRE.
Remedy: DEALERS WILL REPLACE THE ENGINES FRONT VALVE COVER AND FRONT-VALVE-COVER GASKET WITH NEW PARTS OF AN IMPROVED DESIGN AND REMOVE THE ENGINES PLASTIC COVER AND PLASTIC OIL-FILL-TUBE EXTENSION, FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING MAY 2016.

CERTAIN PASSENGER, MINI VANS, AND SPORT UTILITY VEHICLES HAVE AN AIR BAG INFLATOR ON THE DRIVER'S SIDE THAT COULD FRACTURE AT A WELD DURING A DEPLOYMENT.
Consequence & remedy
Consequence: PIECES OF THE INFLATOR COULD STRIKE AND INJURE VEHICLE OCCUPANTS AND THE AIR BAG CUSHION WOULD NOT INFLATE FULLY, REDUCING THE CAPABILITY OF THE BAG TO PROTECT THE DRIVER.
Remedy: DEALERS WILL INSPECT, AND REPLACE, IF NECESSARY, THE AIR BAG MODULE ASSEMBLY ON THE DRIVER'S SIDE. OWNER NOTIFICATION BEGAN AUGUST 15, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT BUICK AT 1-800-521-7300, CADILLAC AT 1-800-458-8006, CHEVROLET AT 1-800-222-1020, GMC AT 1-800-462-8782, OLDSMOBILE AT 1-800-442-6537, OR PONTIAC AT 1-800-762-2737.
