Known Problems

Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.

The remote keyless entry system may not function intermittently. Our technicians tell us revised software for the wireless ignition node is available which can correct this concern.

A small leak from loose charcoal in the charcoal canister (part of the Evaporative Emissions System) may cause Check Engine Light illumination.

If the downstream (rear) oxygen sensor wiring harness contacts the propeller (drive) shaft, it can damage the oxygen sensor and the wiring harness for the sensor, and/or cause Check Engine Light illumination. The wiring harness should be repaired and secured away from propeller shaft.

A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.

A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.

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 AC evaporator drain commonly clogs and causes water to leak onto the passenger side floor. A sloshing noise may also be heard from the water inside the heater housing. Decaying organic debris in the housing may cause an odor. A service bulletin (TSB 24-06-96) was released; it describes how to clean the drain tube without removing the heater AC housing.

The power window motor commonly fails in the front and rear doors. This may require replacement of the complete window regulator assembly which will include the window motor.

Software updates are available to address erroneous illumination of the "Service 4WD System" warning light and other issues (e.g. shifting, performance).

On Vehicles with a 3.7L V6 or 4.7L V8 engine, the Check Engine Light may illuminate with code P013A and/or P013C. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

On Vehicles with a 4.7L or 5.7L V8 engine, the Check Engine Light may illuminate with code P2181 for a cooling system performance fault. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

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