2025 Hyundai Ioniq 5 Inner Rear Lamp LED Inoperative TSB

Certain 2025 Hyundai Ioniq 5 (NEA EV) vehicles may experience a condition where some or all of the Light Emitting Diodes (LEDs) in the inner rear combination lamp are inoperative. This issue specifically affects the LEDs housed within the inner rear combination lamp assembly, which are part of the auxiliary lamp circuit. It is important to note that this condition does not impact the functionality of the brake or turn signal operation.

This technical service bulletin, 25-BE-011H, provides a detailed procedure for Hyundai technicians to inspect the inner rear combination lamp and, if necessary, replace the entire assembly to resolve the inoperative LEDs.

Symptoms

Owners of affected 2025 Hyundai Ioniq 5 vehicles may observe the following symptom:

• Some or all LEDs on the inner rear combination lamp are inoperative.

This issue pertains specifically to the auxiliary lighting function and does not affect critical safety lighting such as brake lights or turn signals.

Important Warnings for Owners

Hyundai has issued several important notices regarding this TSB:

• "To avoid any potential damage to IONIQ vehicles, IONIQ repairs can only be performed at IONIQ certified dealers."
• "If the inside rear combination lamps are working as designed, but other concerns are present, this TSB does NOT apply. Diagnose and repair per the shop manual."
• "The incident parts 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."

Diagnosis and Trigger Conditions

To diagnose the 2025 Hyundai Ioniq 5 inner rear lamp issue, technicians will perform a specific test:

1. The vehicle's key fob is removed, and all doors are closed.
2. The technician stands approximately 8 feet away from the rear bumper with the key fob.
3. The lock button on the key fob is pressed 15 times, with a 1-second pause between each press. During this process, the entire rear tail lamp will cycle ON and OFF.
4. The technician observes the inner rear combination lamps to ensure all LEDs are working as designed.

If the inner rear combination lamp LEDs are not working as designed, the replacement procedure outlined in TSB 25-BE-011H is then followed.

Repair Procedure Summary

The repair for the inoperative 2025 Hyundai Ioniq 5 inner rear lamp involves inspecting the lamp and replacing the assembly if necessary. The procedure includes several steps for removal and installation:

1. Preparation: Technicians must first remove the trunk handle cover by unscrewing two Phillips screws. A plastic trim removal tool is recommended to prevent damage.
2. Trunk Switch Removal: The trunk switch is carefully pried outward, its connector disconnected, and the switch removed.
3. Tailgate Trim Removal: The tailgate lower trim is removed using a panel removal tool, carefully prying the corners and then pulling the entire trim away from the tailgate assembly.
4. Lamp Disconnection: The electrical connector for the inside rear combination lamp is disconnected.
5. Lamp Removal: Nine 10 mm nuts securing the lamp are removed. The lamp is then carefully removed. If it does not come out easily, a flat tool is used to push a plastic locking tab inward.
6. Reinstallation: All components are reinstalled in the reverse order of removal. Proper tightening torque is crucial for all fasteners to prevent future issues. The specified tightening torque is 1.8 lb-ft (22 lb-in or 2.5 N.m).
7. Final Inspection: After reassembly, the operation of the tail lamps is inspected to confirm the repair.
