2004 Chevrolet Malibu Problems
The fuel gauge may not read correctly and/or the Check Engine Light may illuminate with code P0455/P0461 stored for a fuel level sensor issue. These faults may be caused by a fuel vapor line inside the fuel take interfering with the fuel level sensor. If this is found to be the case, repositioned and securing the vapor line should correct this concern. If no fault is found with the fuel vapor line, the fuel level sensor itself may be at fault.
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.
2004 Chevrolet Malibu Questions
Lost all power to everything but the starter and a grounded test light lights up when you touch the engine. What could cause this?
I have 55psi on the fuel rail when I turn the key on, the coils fire when you turn it over but will not start, the pass lock light does not stay on and there are no codes showing on the scanner.
2004 Chevrolet Malibu Recalls
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.
Increased resistance in an electrical connection at the body control module (BCM) may result in voltage fluctuations in the brake pedal sensor circuit. These fluctuations can cause concerns with various systems that monitor the position of the brake pedal, any of which would increase the risk of a crash. Dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to both the BCM and harness connector and the BAS and harness connector, and will reprogram the brake pedal sensor to correct these concerns.
The vehicles being recalled are equipped with an electric power steering (EPS) assist system. The EPS can fail unexpectedly while driving. If this were to occur, steering ability would be maintained but much greater effort would be necessary to steer the vehicle, especially at slow speeds. One of four remedies will be applied depending on the model and year. Parts are not yet available so expect a second notification when they are.
2004 Chevrolet Malibu Reviews
Bought this car used 1 year ago. Since then, I have silenced most of the interior noise by tightening snaps/screws/filling gaps with tissue. Brakes were good when I bought the car, are completely shot, after only 10,000 additional miles of easy driving. Steering is electronically assisted, but randomly cuts out at slow speeds, such as turning after stop signs or backing out of driveways. Go...
If you are thinking about buying a used Malibu, don't. Slow speed turning is clunky. Brakes do not hold up well. Check engine light required an exception for state inspection. No one could fix it. On the positive, it is a good size car for a family of four including having adequate trunk space.
My malibu is a pretty good car for the price.
