2003 Pontiac Grand Am ProblemsNo Start Due to Failed Passlock Sensor
The passlock sensor in the ignition lock cylinder may fail causing an anti-theft system fault and a no start condition. Our technicians tell us that the ignition lock cylinder should be replace to correct this condition.
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 may be the result of a loose or worn gas cap.
2003 Pontiac Grand Am Questionsrough idle, egr valve pipe smashed in, changed coil pack still idles roughly (2 answers)
I wasn't driving but it supposedly went up to 200 degrees... But didn't go over that, but the interior felt really hot I guess. Could that be the thermostat or just something that happens when the oil needs to be changed?
2003 Pontiac Grand Am RecallsIgnition 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.
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.
