Symptoms

Owners of affected vehicles may observe the following symptoms related to the AVN 5th Gen Wide system:

• The radio application frequently crashes when the system is in radio mode.
• A message stating "Uneven Road Ahead, Drive carefully" appears on the instrument cluster.
• A warning sound accompanies the "Uneven Road Ahead, Drive carefully" message.

These symptoms indicate a potential software malfunction that can be resolved with the update outlined in TSB 24-BE-002H.

Important Warnings for Owners

It is crucial to be aware of specific conditions during the software update process to prevent damage or incomplete installation:

• Do not remove the USB drive, or turn off the ignition switch during the update. Interrupting the update can prevent its completion and potentially lead to data loss or system failure.
• During the update, the Hyundai logo may appear multiple times, or the display may temporarily go black. This is considered normal behavior.
• The update will continue even if the vehicle is turned off. However, during the update, certain features, including the rear camera and audio, will be restricted.

Repair Procedure Summary

The resolution for the Hyundai AVN radio app crash and warning message involves updating the AVN system software using a USB drive. The procedure, performed by a qualified technician, includes these general steps:

1. Ensure the vehicle's battery is sufficiently charged and the ignition switch is turned to the 'ON' position.
2. Access the AVN system's 'Setup' menu and navigate to 'General' settings.
3. Check the current software version. If the version is 221011, 221025, 221115, 221220, or 221228, the update is required.
4. Insert the appropriate USB drive containing the software update into the USB slot.
5. Select 'Update' from the system menu and then 'Start' to begin the software installation.
6. After the update is complete, verify that the software version has been successfully updated to 230203.

This process, identified by Operation Code 30DA22R0, takes approximately 0.3 hours to complete.

Required Parts

Dealers will use specific USB drives for the software update:

• RADIOSWUPDATEA: For Elantra (CN7a) and Santa Fe (TMa) models.
• RADIOSWUPDATEB: For Tucson (NX4a) models.

Each dealer has received one free USB stick for each part number, which can be used for multiple vehicles. In cases where a part replacement is needed and is under warranty, a separate claim should be submitted. If the part is out of warranty, a Prior Approval request for goodwill consideration is required.

Owner Action

If you own a 2023 Hyundai Elantra, Santa Fe, or Tucson and are experiencing a Hyundai AVN radio app crash or the "Uneven Road Ahead, Drive carefully" warning, you should contact your authorized Hyundai dealer. Inform them about the symptoms and reference TSB 24-BE-002H. The software update will be performed under warranty as a campaign-type claim.
