2022-2023 Hyundai Ioniq 5 Tailgate Rattle Noise TSB

Hyundai has released Technical Service Bulletin (TSB) 23-BD-006H, dated April 2023, to address a common concern among owners of certain 2022 and newer Ioniq 5 (NE1) vehicles: a persistent Hyundai Ioniq 5 tailgate rattle noise while driving. This bulletin outlines a specific repair procedure designed to resolve this issue, ensuring a quieter and more comfortable driving experience.

The repair detailed in TSB 23-BD-006H focuses on two key areas: the installation of additional washer pads to the side guide bumpers and a precise adjustment of the tailgate striker. This combination aims to secure the tailgate more firmly, preventing the vibrations that lead to the rattle.

Symptoms

Owners affected by this issue will primarily notice a "tailgate rattle noise while driving." This noise typically originates from the rear of the vehicle, specifically around the tailgate area, and can be particularly noticeable over uneven road surfaces or during vehicle movement.

Diagnosis / Trigger Conditions

The Hyundai Ioniq 5 tailgate rattle is generally observed when the vehicle is in motion, suggesting that vibrations or slight movements of the tailgate against its mounting points are the root cause. A technician would typically confirm the presence of the rattle by driving the vehicle or by manually checking the tailgate's stability and fitment.

Repair Procedure Summary

The repair outlined in TSB 23-BD-006H involves a multi-step process to eliminate the Hyundai Ioniq 5 tailgate rattle:

1. Accessing the Side Guide Bumpers: The tailgate is opened, and the side guide bumpers, located on either side, are identified.
2. Removing Bumpers: The screws securing each side guide bumper are removed, allowing the bumper to be detached from the vehicle.
3. Installing Washer Pads: Three washer pads are installed onto each screw on the backside of the side guide bumper. These pads provide additional cushioning and stability.
4. Reinstalling Bumpers: The side guide bumpers, now equipped with the washer pads, are reinstalled into their original positions.
5. Repeating for Opposite Side: Steps 2-4 are repeated for the side guide bumper on the opposite side of the tailgate.
6. Loosening Tailgate Striker Screws: The screws on the tailgate striker are loosened by exactly half a turn. This is a critical step, as loosening them too much can cause damage.
7. Adjusting Tailgate Striker: A striking pry bar is carefully positioned against the tailgate striker. The pry bar is then struck five times with moderate force to adjust the striker's position.
8. Tightening Tailgate Striker Screws: The tailgate striker screws are then tightened to a specific torque range of 15.9 – 19.5 lbf-ft (21.6 – 26.5 N.m or 2.2 – 2.7 kgf.m).

The primary part required for this repair is the Rear Side Guide Bumper Pad Kit, identified by part number 81738-G1000FFF. This kit includes 16 washer pads, with 12 required for the repair and 4 provided as spares.
