2003 Jeep Liberty Problems
RepairPal has identified the most common problems with the 2003 Jeep Liberty based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
An engine misfire at idle (rough idle), accompanied by illumination or flashing of the Check Engine Light, could indicate a problem with one or more of the intake valves. Revised intake valves & valve locks are available to address this concern.
Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Low fluid level in the differential or transfer case can result in bearing failure. Damaged bearings commonly cause a whine or growl type noise.
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
The sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.
The power window motor commonly fails in the front and rear doors. This may require replacement of the complete window regulator assembly which will include the window motor.
The 3.7L V6 and 4.7L V8 in very cold climates (below freezing temperatures) moisture can collect in the Positive Crankcase Ventilation (PCV) system and freeze. This will cause various drivability problems and there are revised PCV system components to repair this concern.
If the power door locks are buzzing or are intermittently noisy, a new door latch assembly may solve this. The door lock actuators are integrated into the latch assemblies.
Certain 2002-2006 vehicles were recalled to replace the lower ball joints because they were susceptible to damage from moisture. For more information on this recall, please click here»
The automatic transmission may stay in "default" mode with no fault codes stored. Reprogramming the powertrain control module (PCM) may be necessary to correct this concern.
If previous drive belt replacements have not fixed a problem with a chirping belt, there is a service bulletin that outlines a revised drive belt routing.
Broken exhaust manifold bolts can create an exhaust leak; the exhaust manifold gaskets and bolts should be replaced.
Putting a chamfer on the cam bearing caps, as specified in a service bulletin, can solve a "high pitch snapping noise" heard when the engine is idling or slightly above idle.
