SPEEDOMETER BEGAN LOSING SPEED, I.E. BEGAN DROPPING , WITH CRUISE CONTROL ON. NO LOSS OF ROAD SPEED NOTED, DIS-ENGAGED CRUISE CONTROL AND CONTINUED WITH FLOW OF TRAFFIC. SPEEDOMETER CONTINUED TO FALL EVENTUALLY REACHING 0 MPH. SPEEDOMETER BEGAN WORKING AGAIN AFTER SHUTTING VEHICLE OFF. CURRENTLY IT WILL BE VERY SLOW GETTING TO 0 MPH WHEN VEHICLE IS FULLY STOPPED. VERY ERRATIC OPERATION OVERALL. CONTACTED GM CUSTOMER CARE, THEY SAID IT SOUNDS LIKE A BAD SPEEDOMETER STEPPER MOTOR. INFORMED THAT IT IS NOT UNDER ANY RECALL. CURRENTLY NOT REPAIRED DUE TO HIGH COST OF REPLACEMENT. NOTE: VEHICLE IS A 2005 CHEVY IMPALA, OUT OF WARRANTY DUE TO MILEAGE (58,000). *TR

WHEN IT STARTED THE VEHICLE WAS ONLY 2 YEARS OLD AND PURCHASED NEW IT HAD 72K PLUS MILES TO DATE AT THE TIME THERE WERE APPROX 61K MILES ON THE VEHICLE.

THE VEHICLE WAS NOT COVERED UNDER THE MANUFACTURES WARRANTY DUE TO THE NUMBER OF MILES. BUT AGAIN FOR STATE INSPECTIONS THIS IS A SAFETY RELATED PART. *TR

Official recalls
1Jul 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.
