MY ENGINE (V6 3.8L 3800 SERIES) IS LEAKING OIL ON THE ENGINE. MY MECHANIC TOLD ME THIS YESTERDAY (11/2/16) WHEN HE REPLACED THE PLASTIC ELBOWS AS I HAD ANTIFREEZE LEAKING FROM THEM.

I HAVE TO ADD A QUART OF OIL IN BETWEEN OIL CHANGES. I HAVE HAD TO DO THIS SINCE I PURCHASED THE CAR 6/2008. THE CAR HAS BEEN LEAKING OIL FOR AWHILE NOW.

I HAVE BEEN THE SOLE OWNER OF THIS 2005 MONTE CARLO. I HAD AN OIL LEAK AND THE CHEVY DEALER RAN A DYE TEST TO SEE WHERE THE LEAK WAS COMING FROM. THE TEST SHOW IT WAS THE REAR MAIN SEAL THAT WAS BAD. I HAVE TAKEN MY CAR IN ON ALL SCHEDULED OIL CHANGES, RUNNING MOBIL 1 SYNTHETIC (RECOMMENDED) AND HAVING ALL SCHEDULED MAINTENANCE DONE. I DO NOT FEEL A REAR MAIN SEAL SHOULD BE GOING OUT ON THIS LOW MILEAGE VEHICLE (UNDER 50,000 MILES). I FEEL THIS IS A DEFECT. I CALLED THE CHEVROLET CUSTOMER CARE LINE, AND THEY WERE NO HELP. *TR

14V400000 · Electrical System:ignition

Jul 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.
