2023-2024 Hyundai Tucson C-Pillar Garnish Delamination TSB

Symptoms

The primary symptom for affected vehicles is the C-pillar garnish separating or delaminating from its base on your 2023-2024 Hyundai Tucson. This issue can affect the aesthetic appearance and potentially the structural integrity of the C-pillar area.

Diagnosis / Trigger Conditions

To diagnose this condition, technicians will visually inspect the C-pillar garnish for any signs of separation or delamination. The Technical Service Bulletin 24-BD-007H specifies that repair validation photos of the C-pillar garnish delamination must be taken. These photos should include the last six digits of the vehicle's VIN and the date of repair, written on a piece of paper, and then uploaded to Hyundai's STUI system.

Important Warnings

Hyundai has issued a critical note regarding parts return for this service action. The manufacturer states: "Claim is subject to debit if the part is not returned." This means that if a dealer performs the repair under warranty and fails to return the incident parts to the Warranty Technical Center (WTC) when requested, the warranty claim may be charged back to the dealership. Owners should ensure their service center adheres to all part return procedures.

Repair Procedure Summary

The repair procedure outlined in TSB 24-BD-007H involves replacing both the left-hand and right-hand C-pillar garnish assemblies. The process begins with the technician verifying the condition of the C-pillar garnish separating from the base. Even if the delamination is only observed on one side, both C-pillar garnishes are to be replaced.

Following verification, a photo of the C-pillar garnish delamination, clearly showing the last six digits of the VIN and the date of repair, is taken and uploaded to the STUI system. Subsequently, both C-pillar garnish assemblies are replaced with new parts. Technicians are instructed to refer to the shop manual for detailed repair steps, specifically under the section "Body (Interior and Exterior) > Body Side Molding > C Pillar Garnish > Repair procedures." A crucial note advises using a plastic trim removal tool to prevent any damage to the vehicle's body or paint during the replacement process.
