If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.

Most reported Jeep problems
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 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.
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.
A water leak and/or wind noise may develop from the doors or lift gate area. As a result of a leak, water may accumulate on the vehicle floor. While door seals can be a common cause for this type of leak, diagnoses may be required to confirm that a door seal is indeed causing the problem.
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.
If water leaks into the passenger compartment and under the passenger side carpet, an heating, ventilation and AC (HVAC) drain hose is available.
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.
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.
Many reports say that the plastic is breaking and cracking at the door handles of the Jeep Commanders. I have had mine replaced at the cost of $1200 for two of the them. The cause is the spring that activates the door latch when you pull on the handle. If you pull the handle and let it slap back into position, there is a part of the actual handle that will hit the plastic. The spring attached to the handle has a lot of strength and it will ove...
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).
