WHILE DRIVING AT VARIOUS SPEEDS, THE ENGINE WOULD STALL AND SHUT OFF. THE PROBLEM STARTED AT 90,000 MILES. HAVE BROUGHT THE CAR TO THE CHEVY DEALER AND THEY HAVE NOT BEEN ABLE TO DIAGNOSE THE PROBLEM. THE CAR IS NOT GENERATING ANY ERROR CODES. I ALMOST GOT INTO AN ACCIDENT TWICE DUE TO SHUTTING OFF DURING ACCELERATION. I HAVE NOTICED THAT THE STALLING OR SHUTTING OFF STARTS AFTER THE TEMPERATURE REACHES APPROXIMATELY 125 DEGREES F AND HAPPENS RANDOMLY. WHEN I AM OPERATING THE AIR CONDITIONER, THE STALLING IS MORE NOTICEABLE DUE TO THE ENGINE LOAD. SO FAR, THE DEALER HAS REPLACED THE CRANK SENSOR AND IGNITION MODULE WHICH HAS NOT CORRECTED THE STALLING AND SHUTTING DOWN. *TR

DURING AN INSPECTION OF MY 2003 IMPALA, MECHANIC ADVISED OF A COOLANT LEAK IN UPPER INTAKE MANIFOLD (A VERY COMMON DEFECT FOR THIS MODEL / YEAR) AND IT WOULD COST HUNDREDS OF DOLLARS TO REPAIR. NEEDLESS TO SAY, I DID NOT HAVE THE FUNDS TO REPAIR IT AND ALL CARS OF THIS MODEL / YEAR SHOULD BE RECALLED FOR REPAIR. *TR

I TOOK MY 2003 CHEVY IMPALA, V6 2.4 L, TO A JIFFYLUBE FOR A STANDARD OIL CHANGE. THERE THEY INFORMED ME THAT I HAD A COOLANT LEAK, AND THEY TOPPED-OFF MY ANTIFREEZE FOR ONLY $4.00.

I TOOK MY 2003 CHEVY IMPALA, V6 2.4 L, TO A JIFFYLUBE FOR A STANDARD OIL CHANGE. THERE THEY INFORMED ME THAT I HAD A COOLANT LEAK, AND THEY TOPPED-OFF MY ANTIFREEZE FOR ONLY $4.00. SINCE REPAIRS AREN'T AFFORDABLE AT THE MOMENT, I CONTINUED TO DRIVE MY IMPALA TO SCHOOL AND WORK ONLY. I WAS ON MY WAY TO CLASS EARLY ONE AFTERNOON, ABOUT A WEEK AFTER MY OIL CHANGE AND MY ENGINE WAS OVER HEATING AND ENGINE COOLANT WAS COMPLETELY GONE. LUCKILY I WAS ONLY 2 MILES FROM MY HOME AND HAD A FRIEND RUN SOME ANTIFREEZE AND WATER TO MY BREAK-DOWN LOCATION. I PUT ENOUGH ANTIFREEZE AND WATER INTO THE RADIATOR TO GET ME HOME, WHERE MY CAR WILL SIT UNTIL REPAIRED. IT IS TO MY UNDERSTANDING THAT ALL 2003 V6 2.4 L IMPALAS HAVE THIS PROBLEM. IF THAT IS THE CASE, WHY HASN'T GM RECALLED THIS VEHICLE FOR PROPER REPAIRS? AN INVESTIGATION INTO THIS MATTER WOULD BE GREATLY APPRECIATED FROM A STRUGGLING AMERICAN THAT LIVES IN A REGION OF THE COUNTRY WHERE PUBLIC TRANSPORTATION IS OBSOLETE AND A MOTORIZED VEHICLE IS A NECESSITY. *TR

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.

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.
