Mopar recall: Power train

What is wrong

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.

What could happen

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.

The fix

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.
