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.
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.
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.
Intermittent problems with the radio can typically be solved by updating the radio software.
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 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.
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.
Poor AC performance or no cold air blowing from vents is commonly caused by a refrigerant leak from the AC condenser . Road debris like rocks or pebbles can damage the condenser tubes.
