Known Problems

The door molding may become loose on one or both front doors. Our technicians recommend to replace the molding if this occurs.

On Vehicles with a 4.7L or 5.7L V8 engine, the Check Engine Light may illuminate with code P2181 for a cooling system performance fault. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

Software updates are available to address erroneous illumination of the "Service 4WD System" warning light and other issues (e.g. shifting, performance).

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.

On Vehicles with a 3.7L V6 or 4.7L V8 engine, the Check Engine Light may illuminate with code P013A and/or P013C. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

Engine oil leaks from the valve cover gasket, oil pan gasket and timing cover gasket are common.

Water may enter the liftgate ajar switch and corrode the switch connectors. This can cause the information center to display the liftgate ajar warning, the rear wiper to be inoperative, the interior lamps to stay on, the security alarm not to set, and/or the battery to drain when the engine is off. A new liftgate ajar switch is needed and the harness connector should be repaired.

A water leak from the sunroof and/or headliner is often caused by clogged or misrouted sunroof drain tubes. Inspecting the sunroof drain tubes should be the first step in checking for the cause of these type of water leaks.

The head gasket may seep oil externally. An updated head gasket is available that will prevent any more oil seepage.

The Check Engine Light may illuminate with code on or more of the following codes: P2302, P2305, P2308, P2311, P2314, P2317, P2610. Reprogramming of the PCM will be necessary to correct this concern.

Due to misfires, you may experience a loss of power when accelerating between 50 and 70 MPH (most noticeable below 32° F). This is commonly caused by carbon buildup on the valve stems, as a result the exhaust valves may close too late. All of the exhaust valves should be inspected and if necessary the engine should be decarbonized.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

A cleaner/lubricant is available from Mopar for when the soft top window zippers become stiff or difficult to move. Our technicians note this product works very well when the directions are followed properly.
