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.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.
DESCRIPTION OF COMPONENT
POWER TRAIN:DRIVELINE:DIFFERENTIAL UNIT
RESOLUTION
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.
