Known Problems

On Vehicles with a 4.7L or 5.7L V8 engine, the Check Engine Light may illuminate with code P2181 for a cooling system performance fault. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

On Vehicles with a 3.7L V6 or 4.7L V8 engine, the Check Engine Light may illuminate with code P013A and/or P013C. Or technicians tell us that updated software for the powertrain control module (PCM) is available to correct this concern.

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.

For the first few miles driven (before the brake pads warm up), the rear brakes may squeal with light brake pressure. Updated rear brake pads are available.

The manual transmission may jump out of gear. Our technicians tell us that replacing the 1-2 synchronizer assembly 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.

An engine overheating condition may develop due to a coolant flow issue. Our technicians tell us that debris may block the cylinder head coolant port at the primary thermostat housing. Removing the debris should correct this concern.

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.

Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.

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.

Floor pan rust and corrosion typically happens where salt or mud is allowed to accumulate on the vehicle. Holes drilled in the floor can contribute to rust if the bare metal is not painted or protected with corrosion resistant coatings. Floor pan kits are available from Jeep and the aftermarket to repair rusted areas.

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.

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.

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.
