Official summary
Some 2011-14MY Sonata (YF) vehicles may exhibit 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) and is valid for original and subsequent owners. Follow the service procedure in this TSB to inspect the rear combination lamps and, if necessary, replace them if heat deformation is found.
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.
