2003 Chevrolet Malibu RecallsIgnition Lock Cylinder Concern

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.
GM has recalled certain 2003 Chevrolet Malibu, Oldsmobile Alero, and Pontiac Grand Am vehicles because the accelerator may stick in hot temperatures, which can increase the risk of an accident. Dealers will inspect the accelerator pedal arm and replace the accelerator and brake pedal assembly.
