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

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.

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.

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.

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).

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.

Vehicles equipped with the multiple displacement system (MDS) must use the correct 5W-20 oil in order to function properly.
Software updates are available to address erroneous illumination of the "Service 4WD System" warning light and other issues (e.g. shifting, performance).
