2023-2024 Jeep Wrangler TBM FOTA Software Update

Stellantis has released Technical Service Bulletin (TSB) 08-138-24 to inform dealers about a Firmware Over The Air (FOTA) software update for the Global Telematics Box Module (TBM) in certain 2023-2024 Jeep Wrangler vehicles. This update, from software version 5.15 to 5.43, aims to resolve several customer-reported issues related to remote functions and vehicle health reporting.

This TSB applies to 2023-2024 Jeep Wrangler models equipped with an Instrumental Panel Parts Module (Sales Code X81) with Connectivity - US/CANADA (Sales Code RTM) and a Global Telematics Box Module (Sales Code RDG). The national launch for this FOTA update was expected to begin on June 14, 2024.

Symptoms

Owners of affected 2023-2024 Jeep Wrangler vehicles may experience one or more of the following symptoms due to the TBM software issue:

• "Remote door lock and unlock commands sent from the Jeep mobile app fail."
• "After saving the edited charge or climate schedule in the radio, the mobile app reverts it back to the schedule set on the Jeep mobile app."
• "Remote operation ignition on remote start not working."
• "Customer not receiving a monthly email containing the VHR (Vehicle Health Report)."

Cause of the Problem

The root cause of these issues is identified as a software anomaly within the Global Telematics Box Module (TBM). The existing TBM software version 5.15 contains bugs that prevent proper communication and functionality with the Jeep mobile app and other vehicle systems.

Important Warnings for Owners

Owners should be aware of critical information regarding this FOTA update:

• Mandatory Update: "The owner will have the option to update the radio or schedule the update for later. There is not an option to decline the update indefinitely, the update must be performed."
• Temporary System Unavailability: During the update process, the Backup Camera, Radio, SOS, and several driving assistance features will be unavailable. This is a normal part of the update and should be anticipated.
• Information Only Bulletin: TSB 08-138-24 is an "Information Only Service Bulletin" for dealers, meaning it is for guidance on how the FOTA update is performed and does not include a Labor Operation (LOP) for reimbursement. This means the update is typically performed over-the-air by the owner.
