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.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

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).

Vehicles with manual temperature control may develop a condition where warm air is coming from the instrument panel outlets when cold has been selected. Our technicians tell us a revised air distribution housing is available to correct this concern.

The power right side rear view mirror may not adjust correctly. Our technicians tell us a revised mirror assembly is available which can correct this concern.

Spark knock, noise/vibration/harshness, and/or Check Engine Light issues may develop. Our technicians tell us powertrain control module (PCM) software upgrades may correct these concerns.

The engine may develop a rough idle after cold start with the Check Engine Light illuminated and code P050D stored. Our technicians tell us a powertrain control module (PCM) software upgrade 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.

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.

The Check Engine Light may illuminate with any or all of the following codes: P2302, P2305, P2308, P2311, P2314, P2317, P2610. Our technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

The engine may develop a rough idle after cold start with the Check Engine Light illuminated and code P050D. Additionally, code P2610 may be stored with no other symptoms. Our technicians tell us a powertrain control module (PCM) software upgrade is available to correct these concerns.
