2023 Hyundai Ioniq 5 Ventilated Seat Air Duct TSB

Hyundai has launched Service Campaign 23-01-050H (also known as TAH) for specific 2023 Ioniq 5 (NE1) vehicles. This campaign focuses on inspecting and, if necessary, replacing the front seat air ducts. The campaign aims to resolve issues where owners might experience 'reduced performance of the ventilated front seats' due to damaged air ducts.

This service campaign is crucial for ensuring the proper function of your vehicle's ventilated seating system. Dealers are required to perform this inspection and any necessary repairs on all affected vehicles prior to customer retail delivery and whenever an affected vehicle is in for service.

Symptoms

Owners of affected 2023 Hyundai Ioniq 5 vehicles may notice a 'reduced performance of the ventilated front seats'. This means the cooling or ventilation function of the front seats may not operate as effectively as intended, potentially diminishing occupant comfort.

Diagnosis and Trigger Conditions

The root cause of the 'reduced performance of the ventilated front seats' is identified as damaged front seat air ducts. These ducts are responsible for channeling air to the ventilated seats. If they are compromised, the airflow is restricted, leading to the observed performance reduction.

Technicians will visually inspect the front seat air ducts for any signs of damage. This inspection is part of the Service Campaign 23-01-050H and is a prerequisite for any replacement work.

Repair Procedure Summary

The repair procedure involves a thorough inspection of the front seat air ducts, followed by replacement if damage is found. The process includes several key steps:

Inspection Process

1. The front seat is moved completely forward to allow access.
2. Straps securing the front seat lower protector are removed.
3. Velcro tape is disconnected, and the upper end of the front seat air duct is detached.
4. Technicians will then check the front seat air duct for any damage. Photos are required for documentation, including the last 6 digits of the VIN, the side of the air duct (driver or passenger), and the date of the repair.
5. These steps are repeated for the other front seat. If no damage is found, no further repairs are needed for the Hyundai Ioniq 5 ventilated seat system.

Replacement Process (if damage is found)

1. The front seat headrest is removed.
2. The front and rear bolts of the front seat track are removed. The tightening torque for these bolts is 42 lb-ft (57 N.m) during reinstallation.
3. The front seat is carefully tilted forward, taking care not to scratch or damage any interior parts.
4. The front seat air duct screw is removed.
5. The damaged front seat air duct is then pulled out for removal.
6. A new front seat air duct is installed. Similar to the inspection, photos of the newly installed air duct are required for documentation, showing the VIN, side, and date of repair.
7. If necessary, the replacement steps are repeated for the opposite front seat.
8. All removed parts are reinstalled in reverse order, ensuring proper tightening of the seat track bolts.

Required Tools or Parts

For the replacement of damaged air ducts, the following parts may be required:

• 88190-G1200: Front seat air duct (Driver seat, LH)
• 88290-G1200: Front seat air duct (Passenger seat, RH)

Important Warnings for Owners

Owners should be aware of several critical points regarding Service Campaign 23-01-050H:

• Dealership Requirement: This service campaign for the Hyundai Ioniq 5 (NE1) can only be performed by IONIQ certified Hyundai dealerships.
• Documentation: All claims submitted by dealerships that have 'incomplete, illegible, or missing documentation' are subject to debit. This emphasizes the importance of proper photo capture during the repair process.
• Part Return: Incident parts that are replaced are subject to callback through the normal Warranty Technical Center (WTC) parts return process. 'Claim is subject to debit if the part is not returned'. This ensures that the manufacturer can properly track and analyze the defective components.

Owner Action

If you own a 2023 Hyundai Ioniq 5 produced between March 5, 2023, and March 30, 2023, and you are experiencing 'reduced performance of the ventilated front seats', you should contact an IONIQ certified Hyundai dealership.
