2021-2024 Hyundai Santa Fe / Tucson Shift-by-Wire Button Peeling TSB

Hyundai has released Technical Service Bulletin (TSB) 23-AT-014H to address a common concern regarding the Shift-by-Wire (SBW) buttons in certain Santa Fe and Tucson models. This bulletin, issued in August 2023, provides a specific repair procedure for situations where the plating on these buttons begins to peel. The good news for owners is that individual SBW buttons are now available as separate service parts, simplifying the repair process.

This TSB is particularly relevant for owners experiencing Hyundai Tucson button peeling or similar issues on their Santa Fe. The focus of TSB 23-AT-014H is to guide technicians on how to replace only the affected buttons, rather than the entire SBW lever assembly, which was previously the only option.

Symptoms of Peeling SBW Buttons

The primary symptom addressed by TSB 23-AT-014H is the peeling of the plating on the Shift-by-Wire buttons. Owners may notice the cosmetic degradation of the "P", "R", "N", or "D" buttons on their center console. This issue is cosmetic but can detract from the vehicle's interior appearance and feel. If you observe Hyundai Tucson button peeling or similar on your Santa Fe, this bulletin provides the recommended solution.

Important Warnings for Owners and Technicians

Hyundai TSB 23-AT-014H includes critical instructions to ensure the correct and efficient repair of the SBW button peeling issue:

• Do not replace the complete SBW lever. The bulletin explicitly states that if replacement of the SBW button is required due to plating peeling, only the button(s) should be replaced with new ones. Replacing the entire SBW lever is unnecessary and will not resolve the issue more effectively.
• For warranty claims, incident parts are subject to callback through the normal Warranty Technical Center (WTC) parts return process. Claim is subject to debit if the part requested is not returned. This means technicians must return the old, affected parts to Hyundai to avoid financial penalties on the warranty claim.
• If a part is found to be out of warranty, a Prior Approval request for goodwill consideration should be submitted before performing the work.

Repair Procedure Summary

The repair procedure outlined in TSB 23-AT-014H involves several steps to access and replace the peeling Shift-by-Wire buttons. Technicians will begin by recording the customer's audio stations and disconnecting the negative battery cable for safety.

Next, a plastic trim tool is used to carefully separate the console upper cover from the lower center console, allowing for its removal. All connectors attached to the console upper cover must be noted for their location, as two connectors are interchangeable, and then disconnected.

The electric shift module, which houses the SBW buttons, is then removed. This step varies slightly between Santa Fe and Tucson models but generally involves removing four screws. For Tucson models (NX4/NX4A, NX4 HEV/PHEV), a screwdriver is also used to release a tab.

Once the electric shift module is out, the black cover protecting the buttons is removed by releasing tabs and unscrewing it. Finally, a screwdriver is used to carefully "pop" the affected peeling buttons off the module. New buttons are then installed in their place.

Reassembly involves reversing these steps: reinstalling the cover, the electric shift module, reattaching all connectors, and securing the console upper cover. After reconnecting the negative battery cable, the customer's audio stations are re-inputted. The final step is to start the engine and confirm that all electric shift buttons function correctly and that the transmission shifts properly into Park (P), Reverse (R), Neutral (N), and Drive (D).

Required Parts

TSB 23-AT-014H specifies various part numbers for the SBW levers and individual SBW buttons, depending on the vehicle model and year. Technicians will refer to the Parts Information table in the bulletin to order the correct replacement buttons. Examples of button part numbers include:

• 467K1-S1100 (BUTTON-P)
• 467K2-S1100 (BUTTON-R)
• 467K4-S1100 (BUTTON-D)
• 467K1-N9100 (BUTTON-P)
• 467K2-N9100 (BUTTON-R)

The corresponding SBW lever part numbers, such as 467W0-S1100-PPJ, 467W0-CL100-RRB, 467W0-N9100-VCS, and 467W0-P0100-VCS, are also listed, though the bulletin emphasizes that only the buttons should be replaced for this specific issue.
