2024 Hyundai Tucson AVN Software Update Campaign 24-01-035H

Hyundai has launched Service Campaign 24-01-035H to address an issue with the AVN 5th Gen Wide system in certain 2024 Hyundai Tucson (NX4A) vehicles. This campaign aims to correct instances where the infotainment system's software is incorrect, leading to a Hyundai Tucson AVN mismatch where functions and images displayed on the system do not align with the vehicle's Owner's Manual.

This software discrepancy can cause confusion for owners and potentially affect the proper use of the infotainment features. The campaign, also referred to as SERVICE CAMPAIGN TBJ, involves a software update to ensure the AVN system operates as intended and matches the owner's documentation.

Symptoms of the AVN Mismatch

The primary symptom of this issue is a Hyundai Tucson AVN mismatch, where the AVN 5th Gen Wide system's functions and displayed images do not align with the information provided in the vehicle's Owner's Manual. Owners might notice discrepancies in menu layouts, feature descriptions, or visual cues that are inconsistent with their manual.

Applicable Vehicles

This service campaign specifically applies to certain 2024 Hyundai Tucson (NX4A) vehicles equipped with the AVN 5th Gen Wide system. The affected vehicles were produced between August 18, 2023, and August 22, 2023.

Important Warnings for Owners

Owners should be aware of several critical points regarding the software update process:

• Do not remove the USB drive, or turn off the ignition switch during the update. Doing so will prevent the update from completing and could potentially damage the system.
• Do not turn off power or remove the USB device. This action may cause data loss or system failure.
• Ensure that the battery is sufficiently charged and that the power is switched to 'ON' to prevent a battery drain during the update. A stable power supply is crucial for a successful update.
• Expect temporary visual changes. There will be multiple occurrences where the Hyundai logo will appear, or the display will be black during the update process. This is normal and does not indicate a problem.
• If your vehicle's AVN system already has software version NX423.USA.S5W_M.V010.002.230517 or newer, the update is not necessary. However, your dealer can still process the campaign to close it out for your vehicle.
