MOPAR POWER TRANSFER UNIT
Check against the official notice below — it lists the full affected range.
Chrysler (FCA US, LLC) is recalling certain Two-Speed Power Transfer Units sold as replacement parts for Jeep Cherokee vehicles due to a defect where input spline teeth can wear off over time. This wear can cause a loss of engagement between the transmission and differential, resulting in a loss of drive while driving and a loss of the Park function while parked, which can lead to vehicle crashes or unintended rollaway.
FCA US LLC will notify owners and dealers will provide a free software update to maintain propulsion by engaging rear wheel drive and prevent rolling in Park by activating the electronic parking brake if a spline failure occurs. If the part is not already installed, it will be replaced with a new part at no charge. Owners should contact FCA USA LLC customer service at 1-800-853-1403 for more information, referencing recall number W48.

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.
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. If the subject part is not installed in a vehicle, it will be exchanged with a new part. All repairs will be conducted free of charge. This recall began July 16, 2020. Owners may contact FCA USA LLC customer service at 1-800-853-1403. FCA's number for this recall is W48.
Chrysler (FCA US LLC) is recalling certain Two-Speed Power Transfer Units (PTU) sold as replacement parts for certain Jeep Cherokee vehicles, part numbers 68090605AJ, 68090605AK, 68090605AL, 68282447AA, 68282447AB, 68282447AC, 68307403AA and 68307403AB. 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.
