2007 Pontiac Grand Prix Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2007 Pontiac Grand Prix


The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also 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. Dealers will provide two replacement key rings and key cover on all ignition keys to correct this concern.

On some vehicles, the fuel tank may be missing the adhesive that bonds the barrier layer to the outer shell.

The recall began November 13, 2006. The GM recall number is 06160.
