In terms of environmental impact, the 2005 Grand Prix produces approximately 444 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Grand Prix has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,450, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $6,500 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Component: 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.

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.
