2018 Jeep Cherokee Problems

The power transfer unit (PTU) may become damaged and disengage the transmission and differential, resulting in a loss of drive power and/or loss of park function. A loss of drive power can increase the risk of a crash. A loss of park function can cause an unintended vehicle rollaway, which can increase the risk of a crash or injury.

Fix: Dealers will update the drivetrain control module and PTU software and replace the PTU, as necessary free of charge.

The powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition. A vehicle stall can increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the powertrain control module, free of charge.

The bearing cage for the right front halfshaft assembly may not have been properly heat treated, possibly resulting in the bearing cage breaking and a potential halfshaft assembly failure. If the halfshaft bearing cage breaks, the halfshaft may not be able to transmit engine power, causing a loss of drive or it can allow the vehicle to move while in the "Park" position. Either condition may increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the front right halfshaft assemblies, free of charge.

These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating. If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. Note: Owners are advised to stop using cruise control until the software update has been performed.

4L engine. These vehicles may have been manufactured with a fuel tube that may leak fuel into the engine compartment. A fuel leak in the presence of the ignition source can increase the risk of a fire.

Fix: Chrysler will notify owners, and dealers will inspect the fuel tube, replacing it as necessary, free of charge.

4L engines. The engines may have a cracked oil pump housing that can result in oil pump failure. If the oil pump fails, the engine will stall, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect the oil pump, replacing it as necessary, free of charge.

The tire and rim size information required to be on the Certification label was omitted during manufacturing, which may result in an incorrect tire and rim combination being installed on the vehicle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 110, "Tire Selection and Rims." The missing tire and rim designation information may lead to an incorrect combination being installed on the vehicle, increasing the risk of a crash.

Fix: Chrysler will notify owners and will provide a corrected certification label, free of charge.
