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 sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.
If the power door locks are buzzing or are intermittently noisy, a new door latch assembly may solve this. The door lock actuators are integrated into the latch assemblies.
Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Low fluid level in the differential or transfer case can result in bearing failure. Damaged bearings commonly cause a whine or growl type noise.
If previous drive belt replacements have not fixed a problem with a chirping belt, there is a service bulletin that outlines a revised drive belt routing.
Putting a chamfer on the cam bearing caps, as specified in a service bulletin, can solve a "high pitch snapping noise" heard when the engine is idling or slightly above idle.
