2004 Pontiac Grand Prix Problems
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.

2004 Pontiac Grand Prix Recalls
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.
In temperatures between -22 and -40 degrees F, and if one of the accelerator pedal return springs breaks, the engine may not return to idle within three seconds as required. If this were to happen, more braking effort may be needed to stop the vehicle. Dealers will replace the accelerator pedal assembly. The recall began March 8, 2005. The GM recall number is 05018.
On some vehicles, the front frame rear body mount bracket may crack. If ignored for too long, the bracket would degrade to a point where the intermediate steering shaft could separate, resulting in a loss of steering control and possibly a crash. Dealers will inspect the front frame assembly and replace it if necessary. The recall began August 16, 2004. The GM recall number is 04056.
2004 Pontiac Grand Prix Reviews
I love the look and ride of my car. I'd like it better if they made all options available on the GT2, instead of only the GTP. Mine is Inferno Orange and gets a lot of looks!
