Warranty extension Z07 OL

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Certain 2021-2023 model year Kona, 2021-2023 model year Kona Electric, and 2022-2023 model year Kona N vehicles may experience an inoperable horn that may be caused by foreign substances causing internal parts to oxidize. 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 replacement 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.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Vehicles listed
HYUNDAI KONA2021, 2022, 2023
HYUNDAI KONA ELECTRIC2021, 2022, 2023 (the catalog's model; the bulletin names a series or trim of it)
HYUNDAI KONA N2022, 2023

Listing a model year does not mean every vehicle of it is concerned: the document says which.
