2008 Pontiac Grand Prix Recalls

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.
