Known Problems

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 surging or bucking during acceleration can be caused if the distributor is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear can cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.

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

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 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.

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.

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.

If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.

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.

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).

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.

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.

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.

A software issue with the sunroof module may lead to a battery drain while the ignition is off. This may cause a dead battery if the vehicle is left parked for a couple days, however reprogramming the sunroof module with new software may fix this problem.
