DTC Quick Navigation
June 11, 2020 NHTSA CAMPAIGN NUMBER: 20E037000
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.
NHTSA Campaign Number: 20E037
Manufacturer Chrysler (FCA US LLC)
Components POWER TRAIN
Potential Number of Units Affected 2,669
Summary
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.
Remedy
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that reprogramming is required and the vehicle must be held overnight.
If the PTU the owner purchased has not been installed, exchange it for a new one.
Alternate Transportation
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that reprogramming is required and the vehicle must be held overnight.
About 2650 Power Transfer Units (part numbers 68090605AJ, 68090605AK, 68090605AL 68282447AA, 68282447AB, 68282447AC, 68307403AA, and 68307403AB) may have been built to allow movement in the PTU between the differential input splines and the transmission output shaft. This condition may result in the teeth of the input splines wearing off, which may eventually cause a loss of engagement between the transmission and the differential inside the PTU. If this occurs, torque cannot be transferred between the front wheels and the transmission, which will result in a loss of motive power while the vehicle is in motion and a loss of the PARK function while stationary. A loss of motive power or PARK function can cause a vehicle crash without prior warning and/or injury to others outside the vehicle.
Repair
If the PTU the owner purchased has not been installed, exchange it for a new one.
Alternate Transportation
Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that reprogramming is required and the vehicle must be held overnight.
FCA US will conduct a Voluntary Safety Recall to reprogram any affected vehicles with software for the Drive Train Control Module (DTCM) and the Electric Park Brake (EPB) that will maintain vehicle propulsion by engaging rear wheel drive and prevent rolling in PARK by activating the electric park 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. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in 3rd Quarter of 2020.
