Check against the official notice below — it lists the full affected range.
Chrysler is recalling certain 2014-2017 Jeep Cherokee vehicles equipped with a two-speed Power Transfer Unit (PTU) because the differential input splines and transmission output shaft may experience relative movement that causes input spline teeth to wear off. When this wear becomes severe enough, the transmission and differential inside the PTU may lose engagement, preventing power from transferring to the front wheels. This can cause a loss of drive while the vehicle is moving and loss of the Park function while stationary, both of which increase the risk of a crash or injury.
FCA US LLC will notify owners, and authorized dealers will perform a software update designed to 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. The recall began July 14, 2020. Affected consumers should contact FCA USA LLC customer service at 1-800-853-1403 to arrange the service, referencing recall number W47.

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.
