Known Problems

A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.

Excessive gear noise can indicate differential bearing failures.

Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

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.

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.

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.

Engine oil leaks from the valve cover gasket, oil pan gasket and timing cover gasket are common.

An abnormal noise and/or vibration may be noted from the front brakes during light braking. Our technicians tell us it may be necessary to replace the steering knuckle and hub assembly, along with resurfacing the rotors to correct this concern.

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.

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.
