Its Shop Time Mondays: Jeep Is Recalling 67,000 Cherokees For Possibly Rolling Away

Power Transfer Unit Input Splines May Break

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: 20V343000

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 LLC will notify owners, and 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. This recall is expected to begin July 31, 2020. Owners may contact FCA USA LLC customer service at 1-800-853-1403. FCA's number for this recall is W47.
