2004 Pontiac Grand Prix Recalls

Engine Oil Leaks Onto Exhaust Manifold

Engine oil can leak onto the exhaust manifold, causing a fire hazard. This concern was addressed in previous recall notifications, but improvements to the repair have been made. Dealers will make improved repairs free of charge to resolve the concern.

Ignition Lock Cylinder Concern

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.

The Engine May Not Return to Idle in Very Cold Climates

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.

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!
