2024 Jeep Wrangler Shifter Inoperative TSB 21-026-25

Owners of certain 2024 Jeep Wrangler vehicles may encounter an issue where the transmission shifter becomes inoperative. This problem, identified as a manufacturing issue, can prevent the vehicle from being shifted out of Park or its currently selected gear. This concern is addressed by Technical Service Bulletin (TSB) 21-026-25, also released as Rapid Service Update (RSU) 25-041, dated March 20, 2025.

This TSB applies to 2024 (JL) Jeep Wrangler vehicles built on or after September 19, 2024 (MDH 0919XX) and on or before September 30, 2024 (MDH 0930XX).

Symptoms of an Inoperative Shifter

If your 2024 Jeep Wrangler is affected by this issue, you may observe the following symptoms:

• The vehicle cannot be shifted out of Park or its current selected gear.
• A warning message, "Service Shifter, Stop Safely, Shut Off Engine To Engage Park," may be displayed on the Instrument Panel Cluster (IPC).

Diagnosis and Trigger Conditions

To determine if your 2024 Jeep Wrangler requires this service, a dealership technician will first check if your vehicle's VIN is listed in VIP or the RSU VIN list. Even if the VIN is not on the list, if the vehicle exhibits the symptoms described above, the repair procedure should be performed.

The diagnostic process involves attempting to shift the transmission out of Park or its current selected gear. If the automatic shifter is able to shift, the bulletin is considered complete, and an inspection labor operation (21-01-03-94) is used to close the active RSU. If the shifter remains inoperative, further action is required.

Repair Procedure Summary

The primary repair for the 2024 Jeep Wrangler shifter inoperative condition involves inspecting the transmission shifter and, if necessary, replacing it. If the shifter cannot be operated, the technician will proceed with replacing the transmission shifter.
