Official summary
Some 2011-14MY Sonata (YF) vehicles may experience inoperative brake lights that may be caused by melting/deformation of the rear combination housing lamps. Hyundai is extending warranty coverage for the rear combination lamp under this condition to 15 years/200,000 miles from the date of original retail delivery or date of first use (whichever occurs first). This warranty extension is valid for original and subsequent owners.
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.
