Known Problems

A loud buzzing or whining when the transmission is in reverse may be caused by a regulator valve in the transmission valve body. A revised valve was released that does not resonate. Careful diagnosis should be performed because other causes can create the noise.

Jeep issued a recall on the ignition switch because the switch could short-circuit in the presence of water or impurities.

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 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.

The power window motor commonly fails in the front and rear doors. This may require replacement of the complete window regulator assembly which will include the window motor.

The ABS light can come on, indicating an ABS pump motor circuit fault. This is most likely to occur in warmer areas (above 90° F) and usually after a quick stop, like a refueling. If no faults can be found in the pump motor circuit after proper diagnostics, there is a revised ABS control module which should correct this concern.

Software updates are available to solve various Check Engine Light and warning light related issues.

The AC evaporator drain commonly clogs and causes water to leak onto the passenger side floor. A sloshing noise may also be heard from the water inside the heater housing. Decaying organic debris in the housing may cause an odor. A service bulletin (TSB 24-06-96) was released; it describes how to clean the drain tube without removing the heater AC housing.

A ticking noise may be noted when vehicle is cold due to an exhaust leak caused by broken exhaust manifold bolts. Replacement of these bolts and associated gaskets is necessary to fix the condition.

Water leaks may be noted from the front and/or rear roof area. Our technicians recommend to inspect the roof ditch and sunroof - Check all grommets and plugs, reseal roof seams, and replace the sunroof drain tubes if necessary.

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.

Vehicles equipped with a MYGIG radio may encounter a dead battery condition. This can be caused by the radio not powering down properly. Flickering of the radio backlighting when the radio should be powered down would indicate a fault requiring replacement of the radio.

Water leaks may be noted from the front and/or rear roof area. Our technicians recommend to inspect the roof ditch and sunroof - Check all grommets and plugs, reseal roof seams, and replace the sunroof drain tubes if necessary.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.
