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.

The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.

Warm air only may be discharged from the AC system due to a faulty infrared temperature sensor.

A rough idle may be noted after starting the engine cold, along with illumination of the Check Engine Light with code P050D stored. Our technicians tell us the powertrain control module (PCM) software should be upgraded to correct this concern.

The automatic transmission can develop problems like erratic shifting, rough shifting, or delayed gear engagement. Repairs for many of these problems are outlined in service bulletins.

A knocking sound my be heard from the engine at times with the air conditioning on. The cause could be the AC compressor itself, if that is the case there is an updated AC compressor to correct this issue.

The dash mounted trunk release button may not function when the vehicle is locked. Our technicians tell us that updated software for the cabin compartment node (instrument cluster) is available to correct this concern.

To inspect a connector for the cooling fan motor, Dodge issued a safety recall. Coolant may be drawn into the connector, causing a short circuit and potentially an engine fire. Dealers are installing a revised wiring harness and replacing any damaged fan motors.

The remote start or keyless entry system may not function at times. A service repair kit is available which should correct this condition.

Spark plug tube seals fail, causing the tubes to fill with engine oil and the engine to misfire. As a result, the engine may run poorly and fuel economy can suffer.

There have been reports of premature head gasket failure; an updated gasket design is available to correct this problem.

The radio sound may mute intermittently and/or the temperature display may display a metric (Celsius) reading when the display indicates English (Fahrenheit). Both of these conditions can be corrected by updating the radio software.

An engine Oil leak may develop at the cam sensor o-ring seal. Our technicians tell us this is often misdiagnosed as an external head gasket leak.

A defective vehicle speed sensor can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors are also susceptible to corrosion, which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.

A weak or dead battery may be caused by the radio not powering down correctly. If the backlight is flickering every 20 seconds that would confirm the fault and the radio would need to be replaced.
