DTC Quick Navigation

June 11, 2020 NHTSA CAMPAIGN NUMBER: 20V343000

A loss of drive can cause a vehicle crash without prior warning. A loss of the Park function can cause unintended vehicle rollaway which can increase the risk of a crash or injury.

NHTSA Campaign Number: 20V343

Manufacturer Chrysler (FCA US LLC)

Components POWER TRAIN

Potential Number of Units Affected 67,248

Summary

Chrysler (FCA US LLC) is recalling certain 2014-2017 Jeep Cherokee vehicles equipped with a two-speed Power Transfer Unit (PTU). Relative movement in the Power Transfer Unit (PTU) between the differential input splines and the transmission output shaft may cause some input spline teeth to wear off, which may eventually cause a loss of engagement between the transmission and the differential inside the PTU. If this occurs, power cannot be transferred between the front wheels and the transmission which results in a loss of drive while the vehicle is in motion and a loss of the Park function while stationary.

Remedy

FCA US will conduct a voluntary safety recall to reprogram the affected vehicles with software for the Drive Train Control Module (DTCM) and the Electric Park Brake (EPB) that will maintain vehicle propulsion by engaging rear wheel drive function and prevent rolling in the PARK selection by activating the electric park brake if a failed input spline occurs. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in the 3rd Quarter of 2020.

We ask that you please take the time to ensure that your personnel are aware of this communication and are prepared to execute a customer friendly process for inquiries regarding involved vehicles.

Some of the above vehicles may have been built with a PTU which allows relative movement between the differential input splines and the transmission output shaft. This condition may result in the teeth of the input splines wearing off, which may eventually cause a loss of engagement between the transmission and the differential inside the PTU. If this occurs, torque cannot be transferred between the front wheels and the transmission, which will result in a loss of motive power while the vehicle is in motion and a loss of the PARK function while stationary. A loss of motive power or PARK function can cause a vehicle crash without prior warning and/or injury to others outside the vehicle.

SERVICE ACTION

FCA US will conduct a voluntary safety recall to reprogram the affected vehicles with software for the Drive Train Control Module (DTCM) and the Electric Park Brake (EPB) that will maintain vehicle propulsion by engaging rear wheel drive function and prevent rolling in the PARK selection by activating the electric park brake if a failed input spline occurs. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in the 3rd Quarter of 2020.
