Known Problems

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).

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.  

One the 3.9L V6 and 5.9L V8 the carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.

Engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

On the 4.7L V8 engine, the Camshaft position sensor failure can cause the engine to crank but not start or it can cause intermittent stalling. A new camshaft position sensor will be needed.

Some transmission related Check Engine Light problems can be corrected with a software update to the Powertrain Control Module (PCM). Some repairs may also require the installation of revised parts.

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.

On the 3.7L V6 and 4.7L V8, Water may enter the spark plug wells and cause a Check Engine (MIL) light. A seal kit for the ignition coils will prevent further water entry.

On vehicles with a 3.7L V6 and 4.7L V8, water may pass by the cowl screen (at the base of the windshield) in heavy rain or a car wash. This can cause the Check Engine Light to illuminate. A revised cowl screen may be available to fix this problem.

The Check Engine Light may illuminate for many different reasons, some of which may be corrected by updating the software in the powertrain control module (PCM).

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.

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.
