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 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 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.

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.

Verified for the Jeep Cherokee
Jeep issued a recall on some ABS equipped vehicles because seals inside the master cylinder fail. When the seals fail, a loss of pressure is detected causing the ABS hydraulic pump to cycle on more frequently or run continuously. This will lead to premature failure in the hydraulic pump. There is a lifetime warranty on the seals and the hydraulic pump motor. Normal braking will still work but brake pedal effort may increase.
