Official summary
Certain 2023 – 2025 model year IONIQ 6 vehicles may experience an inoperable horn that may be caused by water intrusion through the ventilation hole. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the horn assembly under these conditions has been extended to 10 years / 120,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
