Known Problems

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.

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.

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.

During light to moderate braking, if you experience a vibration in the steering wheel, floor, or seat, or a minor pulsation in the brake pedal, installing revised front brake calipers may help. If the brake calipers are silver in color, they are up-to-date. If the calipers are black in color, the revised calipers are needed and should be installed along with new front brake rotors.

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.

Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

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.

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

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.

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.

A chirp type noise may be noted from the serpentine belt when the steering wheel is at full lock with the engine idling. Our technicians tell us a revised serpentine belt tensioner is available to correct this concern.

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

Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

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.
