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.
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.
The manual transmission may jump out of gear. Our technicians tell us that replacing the 1-2 synchronizer assembly should correct this concern.
The sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.
The Check Engine Light may illuminate with code on or more of the following codes: P2302, P2305, P2308, P2311, P2314, P2317, P2610. Reprogramming of the PCM will be necessary to correct this concern.
The 3.7L V6 and 4.7L V8 in very cold climates (below freezing temperatures) moisture can collect in the Positive Crankcase Ventilation (PCV) system and freeze. This will cause various drivability problems and there are revised PCV system components to repair this concern.
Our technicians recommend against using a power steering fluid that contains Teflon because it can restrict the filter in the power steering fluid reservoir. Only use approved fluids in the power steering system.
