Service bulletin Warranty Extensi

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

Hyundai is extending the multifunction switch assembly warranty to 15 years with unlimited miles from the date of original retail delivery or date of first use (whichever occurs first). A service procedure is provided to replace the multifunction switch assembly. Certain vehicles may exhibit intermittent headlight flickering while driving with light switch on the AUTO light mode. Refer to the warranty and service parts information outlined in the TSB whenever the multifunction switch assembly replacement is required.
