2006 Pontiac Grand Prix Problems

Erratic Shifting of the Automatic Transmission

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Intake Manifold Gasket May Leak Coolant or Engine Oil

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.

Check Engine Light Due to Gas Cap Issue

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

2006 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.

brake lights and turn signals on rear went out replaced fuse and still does not work
I bought this car as my 2nd Grand Prix, the first wasnt so great, had some issues with it, mainly heating problems, way too expensive to fix, but my 06 model is very much worth every penny, only issue ive had is with the headlights, this car handles great, rides good, & just an all around good car, I get many compliments on it, its nothing fancy, just a base model, but its still a very nice car.

Steering wheel column cover warped a little, and sun roof leaks now. Rattle disappeared and vent inse...
