June 11, 2020 NHTSA CAMPAIGN NUMBER: 20V343000

Power Transfer Unit 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: 20V343

Manufacturer Chrysler (FCA US LLC)

Components POWER TRAIN

Potential Number of Units Affected 67,248

 

Summary

Chrysler (FCA US LLC) is recalling certain 2014-2017 Jeep Cherokee vehicles equipped with a two-speed Power Transfer Unit (PTU). 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. This recall began July 14, 2020. Owners may contact FCA USA LLC customer service at 1-800-853-1403. FCA’s number for this recall is W47.

 

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 – W47

FCA US LLC (FCA US) has announced a safety recall on certain 2014 through 2017 Model Year (KL) Jeep_® Cherokee vehicles equipped with Power Transfer Unit (PTU) sales code DK4.  

 

REASON FOR THIS SAFETY RECALL

Some of the above vehicles may have been built with a PTU which allows relative movement 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 the 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 function and prevent rolling in the PARK selection by activating the electric park brake if a failed input spline occurs. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in the 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.

Safety Recall W47 / NHTSA 20V-343 PTU Input Spline

 

Remedy Available

2014-2017

(KL)

Jeep Cherokee

 

NOTE:  This recall applies only to the above vehicles equipped with a Power Transfer Unit (PTU) (sales code DK4).

 

NOTE:  Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.

 

IMPORTANT:  Some of the involved vehicles may be in dealer used vehicle inventory.  Dealers should complete this recall service on these vehicles before retail delivery.  Dealers should also perform this recall on vehicles in for service.

Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The PTU on about 67,240 of the above vehicles may have been built to allow relative movement 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

Reprogram the 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 function and prevent rolling in the PARK selection by activating the electric park brake if a failed input spline occurs.

 

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.

 

Parts Information

No parts are required to perform this service procedure.

IMPORTANT SAFETY RECALL

PTU Input Spline

Dear [Name],

 

This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.

 

FCA US has decided that a defect, which relates to motor vehicle safety, exists in certain [20142017 (KL) Jeep Cherokee] vehicles.

 

It is extremely important to take steps now to repair your vehicle to ensure the safety of you and your passengers.

 

WHY DOES MY VEHICLE NEED REPAIRS?

The Power Transfer Unit (PTU) on your vehicle may allow relative movement 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.

 

HOW DO I RESOLVE THIS IMPORTANT SAFETY ISSUE?

FCA US will repair your vehicle ^[2] free of charge (parts and labor).  To do this, your dealer will reprogram your Drive Train Control Module and Electric Park Brake. The estimated repair time is one hour. In addition, your dealer will require your vehicle for proper check-in, preparation, and check-out during your visit, which may require more time. Your time is important to us, so we recommend that you schedule a service appointment to minimize your inconvenience. Please bring this letter with you to your dealership.

 

TO SCHEDULE YOUR FREE REPAIR,
CALL YOUR CHRYSLER, DODGE, JEEP OR RAM DEALER TODAY

 

WHAT IF I ALREADY PAID TO HAVE THIS REPAIR COMPLETED?

If you have already experienced this specific condition and have paid to have it repaired, you may visit www.fcarecallreimbursement.com to submit your reimbursement request online. ^[3] Once we receive and verify the required documents, reimbursement will be sent to you within 60 days.  If you have had previous repairs performed and/or already received reimbursement, you may still need to have the recall repair performed.

 

We apologize for any inconvenience, but are sincerely concerned about your safety.  Thank you for your attention to this important matter.
