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.
The door molding may become loose on one or both front doors. Our technicians recommend to replace the molding if this occurs.
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 develop a wind noise and/or loss of "express" mode. Our technicians tell us that lubrication the front drive cables, replacing the front header bow, and initializing the sunroof module will generally correct these concerns.
The sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.
The fuel tank may become hard to fill and/or the fuel fill nozzle may shut off repeatedly while fueling. Our technicians tell us that various items including the fuel tank, vapor recirculation tube, fuel fill tube, or EVAP system canister control valve may be at fault. Proper diagnoses will be required to determine the exact cause of this concern.
A popping or groan type noise may occur when opening or closing one or more of the vehicle doors. This may be caused bu insufficient lube on the lower hinge roller axle. Applying a small amount of grease between the roller pin and the inside surface should correct this concern. Our technicians tell us if the grease is not applied in the correct location, the noise will remain.
There are a number of checks to perform if the windows do not move smoothly through their travel. It may be interference between parts, the window regulator, or the window run channel.
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.
