2023 Hyundai Tucson / Santa Cruz Sunroof Inoperable TSB

Hyundai has issued Service Campaign 23-01-013H, also known as Service Campaign T9H, to address an issue affecting the sunroof operation in certain 2023 Hyundai Tucson (NX4a) and Santa Cruz (NXT) vehicles. This campaign provides a guide for dealers to properly initialize the sunroof system, ensuring correct functionality.

This bulletin is crucial for owners experiencing an inoperable sunroof, as it outlines the official procedure to resolve the factory programming oversight. If you are experiencing a Hyundai Tucson sunroof inoperable condition, this information will help you understand the necessary steps.

Symptoms

The primary symptom of this issue is an inoperable sunroof. Owners may find that the sunroof does not respond to controls, or it may not operate through its full range of motion. The sunroofs were not programmed correctly at the factory, leading to this functionality problem.

Diagnosis / Trigger Conditions

The root cause of the Hyundai Tucson sunroof inoperable issue is an oversight during vehicle assembly where the sunroofs were not properly programmed at the factory. This means the problem is present from the time of vehicle delivery for affected units. Dealers are instructed to perform this service campaign on all affected vehicles prior to customer retail delivery and whenever an affected vehicle is in the shop for any maintenance or repair.

Important Warnings for Owners and Technicians

Hyundai emphasizes specific requirements for dealers when performing this service campaign, particularly regarding warranty claims. Dealers must submit claims on the Campaign Claim Entry Screen. If a part not covered by this campaign is found to need replacement while performing the service, and it's still under warranty, a separate claim must be submitted. For out-of-warranty parts, a Prior Approval request for goodwill consideration is required.

Crucially, the operation time for this repair includes taking and uploading a Special Tool Usage Information (STUI) video. This video must clearly display the vehicle's VIN (Vehicle Identification Number) on the VIN plate or door jamb and demonstrate that the sunroof is fully operational after the programming. Hyundai states, "If not included, the claim will be subject to debit." Furthermore, "All claims submitted that do not have a video covering the above items are subject to debit."

Repair Procedure Summary

The repair involves a sunroof initialization procedure to program the sunroof operation correctly. The steps are as follows:

1. Turn the ignition key to the ON position and ensure the sunroof is completely closed.
2. Release the sunroof control lever.
3. Press and hold the CLOSE button for more than 10 seconds. Continue holding until the sunroof closes and moves slightly.
4. Release the sunroof control lever once more.
5. Within three seconds, press and hold the CLOSE button again. Keep holding until the sunroof performs a specific sequence: tilting down, sliding open, and then sliding closed. Once this sequence is complete, release the lever.
6. The reset procedure for the sunroof system is now finished. If the sunroof still does not work after this programming, the procedure should be restarted from the beginning.
