2025 Hyundai Ioniq 5 Automatic Wipers Inoperative TSB

Hyundai has released Technical Service Bulletin (TSB) 26-BE-006H to address a condition where the automatic front wipers on certain 2025 Hyundai Ioniq 5 (NEA EV) vehicles may become inoperative. This issue specifically affects the automatic function of the wipers, which relies on the rain sensor. The wipers will still function on their high and low-speed settings, as these do not depend on the rain sensor.

This bulletin provides instructions for technicians to inspect the rain sensor lens for contamination and, if necessary, replace the affected rain sensor module. Owners experiencing issues with their 2025 Hyundai Ioniq 5 automatic wipers should be aware of this TSB.

Symptoms

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

• Inoperative automatic front wipers: The automatic wiper setting fails to activate the wipers when rain is detected, even though the windshield may be wet. The manual high and low wiper speeds will continue to function normally.

Diagnosis / Trigger Conditions

The root cause for the inoperative automatic front wipers is often a contaminated rain sensor lens. To diagnose this issue, a technician will perform the following steps:

1. The vehicle will be turned on, and the front wiper switch will be set to the "AUTO" position.
2. The designated area on the windshield where the rain sensor is located will be ensured to be clean and free of dirt.
3. A water bottle will be used to spray water onto this designated area to simulate rain.
   • If the front wipers automatically operate, the TSB does not apply, and further normal diagnostic procedures would be followed.
   • If the front wipers do NOT operate, it indicates a failure, and the Rain Sensor Replacement procedure outlined in TSB 26-BE-006H should be followed.

Important Warnings for Owners

Hyundai has issued several important notices regarding this service bulletin:

• Repair Justification: This repair requires a confirmed customer concern and a verified symptom before any repair work can begin. Claims submitted without meeting these requirements may be subject to debit.
• Warranty Coverage: The repair is covered under the 5-year/60,000-mile New Vehicle Limited Warranty (NVLW). Technicians must ensure the vehicle and parts are within this warranty period based on mileage and start date. If the vehicle is out of warranty, dealers may submit a Prior Authorization (PA) Request for goodwill consideration on a case-by-case basis.
• Certified Dealers Only: To prevent potential damage to IONIQ vehicles, all IONIQ repairs, including this rain sensor service, can only be performed at IONIQ certified dealers.
• Part Return: Incident parts that are replaced are subject to a callback through the normal Warranty Technical Center (WTC) parts return process. Claims may be debited if the part is not returned.

Repair Procedure Summary

If the rain sensor inspection confirms the issue, the repair involves replacing the rain sensor module. The general steps for this repair, as outlined in TSB 26-BE-006H, include:

1. Removal of the Old Sensor: The existing rain sensor is carefully removed from the vehicle, following specific instructions in the shop manual related to the Body (Interior / Exterior / Electrical) and Exterior Green House sections.
2. Installation of the New Sensor: A new rain sensor module is then installed. Technicians are cautioned to avoid touching the silicone film on the new sensor to prevent contamination with dirt or debris during installation.
3. Documentation: A photo of the original rain sensor, showing any contamination on the lens, must be taken using the STUI camera function and uploaded. If the STUI camera is unavailable, the last six digits of the vehicle's VIN and the repair date must be written on a piece of paper and included in the photo.
4. Reassembly and Verification: All removed parts are reinstalled in reverse order, and the proper operation of the automatic wipers is verified to ensure the repair is successful.
