The short answer
NHTSA received Chrysler (FCA US LLC)’s report on Jun 11, 2020. Copied from NHTSA on Oct 20, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.
