Known Problems

Replacing a pressure solenoid valve in the transmission valve body may fix an issue where the transmission "hunts" between first and second gears. Our technicians report that customers sometimes describe this complaint as surging or bucking.

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.

If a clunking or "loose lumber" noise is coming from the front or rear suspension, there are revised shock absorbers available that can help the concern. This is usually heard at lower speeds and colder temperatures when driving over bumps.

Software updates are available to solve various Check Engine Light and warning light related issues.

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.

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).

The throttle body may malfunction in very cold climates causing symptoms at engine start up. A throttle body causing problems will require replacement.

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.

If the engine will not crank when the key is turned to "Start," check for a loose connection on the starter solenoid before replacing the starter or battery cable.

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.

Some models could have a severe drift or pull to one side when the brakes were applied. If this is not caused by a dragging brake caliper, there is a service bulletin describing the step-by-step diagnosis and many possible solutions. Our technicians note the most common solutions are performing a four wheel alignment, checking torque on suspension components, installing shims between the wheels and hubs, and replacing the suspension arms.

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.

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.

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.

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.
