Known Problems

If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.

A rough engine idle and/or engine stalling condition may develop, often associated with illumination of the Check Engine Light and an exhaust gas recirculation (ERG) fault code stored. This is commonly caused by a clogged EGR tube. The repair involves cleaning the clogged EGR tube.

The transfer case in the Dodge Durango has multiple gear ratios, which can be selected by moving the switch in the cabin to 2Hi, 4Hi, or 4Lo. It has been known to shift to 4Lo without warning, at any speed, and whether the vehicle is on or off. If this occurs at highway speeds, the result can be catastrophic failure of the transfer case.

This is caused by a faulty four wheel drive shift motor, selector switch (in the cab) or the wiring between the two. The most common cause is the transfer case switch, which is an electric motor mounted on the transfer case. 

To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed. Disconnecting power to the shift motor will lock the transfer case in its current setting.  

A ticking type noise may develop, most noticeable when the engine is cold. This is commonly caused by one or more broken exhaust manifold bolts. Our technicians recommend to replace the broken bolts as needed, also the exhaust manifold gaskets should be replaced at this time.

The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.

Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.

Intermittent problems with the radio can typically be solved by updating the radio software.
A weak or dead battery may be caused by a defective radio (MYGIG radios only). To check, turn off the car and remove the key from the ignition. Wait thirty to forty seconds and then check if the radio back light is flickering. If the back light flickers every twenty seconds, the radio should be replaced.

A whining noise heard driving at freeway speeds (more than 55 mph) can be normal noise from the rear axle which is being transmitted through the body. A body/frame damper is available which may help with this concern.

With the Multi-Displacement System (MDS), repeated Check Engine (MIL) light illumination for low oil pressure may be solved with a software update to the Powertrain Control Module (PCM).
