Jeep Cherokee Transmission Wear

Posted on by

Chrysler will be asking owners of certain 2014-2017 Jeep Cherokee SUVs to return to their dealership to repair a problem affecting the two speed power transfer unit (PTU) in their vehicles. The suspect period began in April 2014 when more robust differential input splines were used to manufacture PTUs.

According to the defect report, movement between the differential input splines and the transmission output shaft may result in the input spline teeth wearing. Eventually this will cause a loss of engagement between the transmission and the differential, and torque will not be transferred to the wheels. The vehicle will loose motive power and there will be no “Park” function while the vehicle is stationary.

Dealers will perform a software update that will maintain vehicle propulsion by engaging rear wheel drive and prevent rolling in “Park” by activating the electronic parking brake if a failed input spline occurs. FCA’s number for this recall is W47 and the NHTSA campaign number is 20V-343.

Chrysler will be contacting the owners of certain 2019 Jeep Grand Cherokee and 2019 Dodge Durango vehicles because of a problem affecting the powertrain of their vehicles.

According to the defect report, the front differential may have been built with pinion gears that were not sufficiently hardened. Over time the gears could wear down until torque power cannot be transferred from the drivetrain to the front wheels. If this happens drivers will experience loss of power and loss of the “Park” function when stationary. Prior to loss of power, drivers may notice a gear whine or grinding noise coming from the drivetrain

Those receiving notices will be asked to return to their dealerships to have the front differential replaced. This recall is expected to begin May 15, 2020. Chrysler’s number for this recall is W22 and the NHTSA campaign number is 20V-183.
