NHTSA Recalls
5 recalls on record from NHTSA. Check your VIN atnhtsa.gov to see if the repair was performed.
ELECTRICAL SYSTEM:IGNITION
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.
POWER TRAIN:MANUAL TRANSMISSION
VEHICLE DESCRIPTION: CERTAIN PASSENGER VEHICLES EQUIPPED WITH MANUAL TRANSAXLES (RPO M86) FAIL TO COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 114, "THEFT PROTECTION." WHEN A DRIVER ATTEMPTS TO SHIFT FROM 5TH GEAR TO REVERSE, A SHIFT INHIBITOR CAUSES THE TRANSMISSION TO BE MECHANICALLY IN 4TH GEAR EVEN THOUGH THE SHIFT LEVER INDICATES REVERSE GEAR.
