2021-2024 Jeep Wrangler Navigation Reboot TSB

Owners of 2021-2024 Jeep Wrangler vehicles, along with other Stellantis models, may encounter issues with their navigation system. This technical service bulletin (TSB), identified as NHTSA Manufacturer Communication 10251848, addresses instances where the navigation system experiences unexpected reboots or interruptions.

This problem, often triggered after a Map Over-The-Air (MOTA) update fails, can lead to a frustrating user experience. The good news is that a straightforward solution involving a USB map update is available to correct the Jeep Wrangler navigation reboot problem.

Symptoms of Navigation Reboot

If you own a 2021-2024 Jeep Wrangler, you might observe one or more of the following symptoms related to the navigation system:

• The radio navigation continues to reboot, especially after a Map Update (MOTA).
• The navigation regularly cuts out and then turns back on again without warning.
• The radio switches to navigation mode without any input from the customer.

These symptoms indicate a potential software issue with the navigation system, specifically when a Map Update (MOTA) fails to complete successfully.

Diagnosis and Trigger Conditions

The primary trigger for the Jeep Wrangler navigation reboot issue is a failure during the Map Over-The-Air (MOTA) update process. When the MOTA update does not complete correctly, it can leave the navigation system in an unstable state, leading to the observed rebooting and cutting out. Dealership technicians will diagnose this by checking for these reported symptoms and confirming if a MOTA update was recently attempted or failed.

Repair Procedure Summary

The resolution for this navigation system anomaly involves updating the navigation maps via USB. This process ensures that the system receives a stable and complete map update, overriding any corrupted or incomplete data from a failed MOTA update. Technicians will connect a USB device containing the latest navigation map data to the vehicle's system and perform the update according to manufacturer instructions.

Owner Action

If your 2021-2024 Jeep Wrangler is experiencing navigation system reboots, cutting out, or unsolicited switching to navigation mode, it is recommended to visit your authorized Jeep dealership. Inform them about the symptoms you are experiencing and mention NHTSA Manufacturer Communication 10251848.
