June 11, 2020 NHTSA CAMPAIGN NUMBER: 20E037000

Power Transfer Input Splines May Break

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

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 is expected to begin July 31, 2020. Owners may contact FCA USA LLC customer service at 1-800-853-1403. FCA's number for this recall is W48.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

New Safety Recall Advanced Communication – W48

FCA US LLC (FCA US) has announced an equipment safety recall on some Power Transfer Units (PTUs) (part numbers 68090605AJ, 68090605AK, 68090605AL 68282447AA, 68282447AB, 68282447AC, 68307403AA, and 68307403AB).

 

REASON FOR THIS SAFETY RECALL

Some 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.

 

SERVICE ACTION

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.

We ask that you please take the time to ensure that your personnel are aware of this communication and are prepared to execute a customer friendly process for inquiries regarding involved vehicles.
