Chrysler is recalling 67,248 model year 2014-2017 Jeep Cherokees with a two-speed Power Transfer Unit (PTU).

Relative movement in the 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 warning. A loss of the Park function can cause unintended vehicle rollaway which can increase the risk of a crash or injury.

What to do

Chrysler 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 Chrysler customer service at (800) 853-1403. Chrysler's number for this recall is W47.
