2003 Chevrolet Impala ProblemsTransmission Pressure Control Solenoid Failure May Cause Erratic Shifting
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.
The engine light was on and the car seemed to be running fine. That is when i went in to hook it up to the diagnostic machine. We found out it was the oil pressure sensor. You do have to order the part through GM, but it is only $10.00. my husband fixed it in about 10 min.
The catalytic converter may become plugged resulting in loss of engine power. General Motors has extended the catalytic convertor warranty on some models to 10 years or 120,000 miles. Please contact your local GM dealer to see if your vehicle is included.

2003 Chevrolet Impala RecallsEngine 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.
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.
