2004 Chevrolet Impala Problems

Check Engine Light Due to Gas Cap Issue

A Loose or worn gas cap may cause Check Engine Light to illuminate.

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.

Stalling Due to Mass Air Flow or Crankshaft Position Sensor Failure

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

2004 Chevrolet Impala Recalls

Engine 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.

Engine Oil Leaks

Engine oil may leak from the valve cover area, which can cause a burning odor and increase risk of fire. Dealers will replace the spark plug wire retainer to redirect the dripping oil on affected vehicles, and will replace the left valve cover gasket on vehicles with the 3.8L V6 supercharged engine.

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.

2004 Chevrolet Impala Reviews

the side of driver no fuction the heat and rarely i came my house and let the car and its no start after, at 6 hour of city.
I love my impala but, I had to replace turn signal arm twice.If the arm damage your lights will not work. There is a problem with Dex coolant. It mess up intake manifold gaskets. Had to replace the computer four years after buying the car. There was no recall from GM due to the coolant. Why I don't know.
I have 183,000 miles on the car. The instrument cluster has been causing problems for quite a while now, and I will have to get it fixed. Overall, those this has been a great car. The gas mileage is still great - 27pmg all around driving. No other problems. I am hoping for at least 250,000 miles.
