Jeep Cherokee: Powertrain
Affects Jeep Cherokee · 2014–2017 — about 14K vehicles.
The hazard
Issue: On certain vehicles with a two-speed power transfer unit (PTU), the input splines on the front differential may wear and fail. If this happens, there could be a loss of power to the wheels. In addition, the PARK position may not hold the vehicle in place. This could allow the vehicle to move unexpectedly when parked. Safety Risk: A vehicle that loses power to the wheels or moves unexpectedly could increase the risk of a crash. Corrective Actions: FCA will notify owners by mail and instruct you to take your vehicle to a dealer to update the software for the power transfer unit. This update will maintain vehicle propulsion by engaging rear wheels if the input splines fail. It will also prevent the vehicle from moving unexpectedly when transmission is in PARK by activating the parking brake.
