Known Problems

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

Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.

If water leaks into the passenger compartment and under the passenger side carpet, an heating, ventilation and AC (HVAC) drain hose is available.

Loose or worn suspension and steering components can cause a wobble or shaking in the steering wheel. It may happen at a certain speed and subside as the vehicle accelerates through the range. Tire balance can contribute to this as well.

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.

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

Some models are susceptible to rear main oil seal failures in dirty or dusty conditions. As dirt and dust collect on the oil seal, the abrasion wears through the sealing surface. A spacer is used between the bell housing and engine that has a small slot in the 12 o'clock position. Filling this slot with RTV silicone and cleaning the seal area can help prevent damage to the seal.

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.

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.

When normal alignment practices do not bring components into the alignment specifications, offset upper ball joints are available.

"False" trouble codes may cause erroneous illumination of the Check Engine Light. Updating the PCM software can often correct this concern.

The throttle body may accumulate an oily, black residue in the bore and on the throttle plate causing hard starting or possibly stalling when coming to a stop. The throttle body should be cleaned during regular maintenance but do not spray cleaners directly on or at the throttle position sensor (TPS) as this can damage the sensor.

Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

The tailgate hinges can corrode making it difficult to open the tailgate.
