Known Problems

On the 3.7L V6 and 4.7L V8 the Exhaust manifold bolts commonly break, exhaust manifold gaskets should be replaced and replace bolts as needed.

On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.

If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the "OK to start" signal.

On the 3.9L V6 and 5.9L V8 the 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 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.

If the vehicle will not shift into, or out of four wheel drive, and the "Serv 4WD" warning light is illuminated, the front axle disconnect actuator may need replacement and a power module (TIPM) may need a software update.

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.

If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.

On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.

On the 3.7L V6 and 4.7L V8 the camshaft position sensor may fail and cause the engine to crank but not start or it can cause intermittent stalling. A failed camshaft sensor will require replacement.

The track for the power seat may need to be replaced if the seat rocks when the vehicle accelerates or slows down.

Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.

Battery acid can leak on, and deteriorate a vacuum hose for the speed (cruise) control system. If the hose becomes loose or leaks vacuum, the speed (cruise) control will not function.

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.
