45A / NHTSA 23V-302 PTU Input Spline – 2016-2017 Jeep Cherokee

SEOCONTENT-START

SAFETY RECALL – NORTH AMERICA PTU Input Spline Reference: 45A / NHTSA 23V-302 FCA US LLC _________________________________________________________ Strictly respect STELLANTIS Group safety, cleanliness, and environmental instructions for any vehicle service. Document exclusively reserved for dealer information. Internal distribution to be ensured by dealer. Reproduction forbidden without the written agreement of STELLANTIS Group. (DJT) 1/4 Remedy available for 2016-2017 Cherokee Template Version 1.8 Revision Edition Detail 0 May 2023 Initial Version. SYMPTOM DESCRIPTION The PTU on about 25,980 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. SCOPE 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 new vehicle inventory. Federal law requires you to complete this recall service on these vehicles before retail delivery. Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service. Involved vehicles can be determined by using the VIP inquiry process. REPAIR TO BE PERFORMED 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. COMPLETION REPORTING / REIMBURSEMENT Claims for vehicles that have been serviced must be submitted on the DealerCONNECT Claim Entry Screen located on the Service tab. Claims paid will be used by FCA to record recall service completions and provide dealer payments. Use the following labor operation numbers and time allowances: Labor Description Number Hrs Inspect DTCM/EPB Software Levels 18-45-A1-81 0.2 hours Inspect DTCM/EPB Software Level and Reprogram DTCM and EPB with New Software 18-45-A1-82 0.3 hours NOTE: See the Warranty Administration Manual, Recall Claim Processing Section, for complete recall claim processing instructions.

(DJT) 3/4 SERVICE PROCEDURE A. Drive Train Control Module (DTCM) NOTE: The wiTECH scan tool must be used to perform this recall. If the reprogramming flash for the DTCM or EPB is aborted or interrupted, repeat the procedure. 1. Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge. NOTE: Use an accurate stand-alone voltmeter. The battery charger volt meter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage. 2. Connect the wiTECH micro pod II to the vehicle data link connector. 3. Place the ignition in the “RUN” position. 4. Open the wiTECH 2.0 website. 5. Enter your “User id” and “Password” and your “Dealer Code”, then select “Sign In” at the bottom of the screen. Click “Accept”. 6. From the “Vehicle Selection” screen, select the vehicle to be updated. 7. From the “Action Items” screen, select the “Topology” tab. NOTE: The DTCM must be at the latest software calibration level after completing this recall. 8. From the “Topology” tab, select the “DTCM” module icon. 9. From the “Flash” tab, compare the “Current Electronic Control Unit (ECU) Part Number” with the “New ECU Part Number” listed. ➢ If the “Current ECU part Number” is the same as the “New Part Number”, proceed to Step B. Electric Park Brake. ➢ If the “Current ECU part Number” is NOT the same as the “New Part Number”, continue with Step 10. 10. From the DTCM tab, select the DTCM flash part number. Read the flash special instructions page. Select “OK” to continue. 11. From the flash ECU agreement page, agree to terms by checking the box.

The suspect period began on September 3, 2015, when PTUs with a revised design started to be used in vehicle production, through September 23, 2016, when PTUs with more robust differential input splines started to be used in vehicle production. The vehicle population was determined by supplier and vehicle assembly traceability records. Similar vehicles not included in this recall do not have a PTU, were built with a PTU of a different design, or were built with differential input splines that are more robust.

If this occurs, torque cannot be transferred between the front wheels and the transmission which results in a loss of motive power while the vehicle is in motion in two-wheel drive mode and a loss of the PARK function while stationary. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : A loss of motive power can cause a vehicle crash without prior warning. A loss of PARK function can cause a vehicle crash without prior warning and/or injury to others outside the vehicle.

Description of Remedy : Description of Remedy Program : FCA US will conduct a voluntary safety recall to flash the affected vehicles with software that will maintain vehicle propulsion by engaging rear wheel drive and prevent rolling in PARK by activating the electric parking brake if a failed input spline occurs. FCA US has a longstanding policy and practice of reimbursing owners who have incurred the cost of repairing a problem that subsequently becomes the subject of a field action. To ensure consistency, FCA US, as part of the owner letter, will request that customers send the original receipt and/or other adequate proof of payment to the company for confirmation of the expense. How Remedy Component Differs from Recalled Component : The remedy component will be a software flash that, if failure of the input splines occurs, causes a malfunction indicator lamp to illuminate, rear axle engagement to prevent a loss of motive power, and electronic parking brake activation when the vehicle is in PARK to prevent a loss of PARK function. Identify How/When Recall Condition was Corrected in Production : NR Recall Schedule : Description of Recall Schedule : **04/27/2023: FCA US will notify dealers and begin notifying owners on or about 06/16/2023.

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 in two-wheel drive mode 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. The remedy for this condition is not currently available. Dealers will be notified of the launch of this safety recall by way of established communication methods.
