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.

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

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.

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.

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.

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 rubber plug, installed above the starter, is being used in production that prevents the dust entry near the seal and extends the life of the seal. The plug is available from MOPAR and should be installed any time a rear main seal service is performed.

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.

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.

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

Certain 2002-2006 vehicles were recalled to replace the lower ball joints because they were susceptible to damage from moisture. For more information on this recall, please click here»

The outer exhaust manifold studs can break and cause exhaust leaks, commonly noted as a ticking type noise. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs).

Vehicles equipped with manual transmissions may become difficult to shift. The repair may involve replacing the 3rd/4th/5ht & reverse gear synchronizer rings as a set.

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.

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

As a Jeep Liberty owner with a sky slider, I have also having ongoing issues with the slider breaking, not closing, or opening, and being given the run around by Jeep Corp. Now, like many who have posted here, and other forums, I am now the owner of a Jeep Liberty that has a giant hole in the roof because the top does not close. I am informed by Jeep the cost is upwards of $2800. I am the first, and only owner and have kept it in pristine cond...
