Known Problems

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.

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 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 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.

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

If the door locks intermittently lock and unlock without pressing the door lock switch, the door lock cylinder switches may need replacement. This may occur more often when driving in damp conditions like the rain or through a car wash.

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.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address 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).

On the 3.9L V6, 5.2L V8 and 5.9L V8 the Oil leaks commonly from the valve cover gaskets, intake manifold gaskets (front and rear), timing cover gaskets, distributor O-ring, and the rear main seal area. Using fluorescent engine oil dye can be helpful in determining the source(s) of the oil leak.

The drip rail door seal may become torn form contact with the lower A-piller. A revised secondary door seal is available to correct this concern. This is not a recall but a technical service bulletin (TSB) which means the failed part will be replaced at the customers expense once the warranty has expired.

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