Official summary
Some customers may complain that the front seat warmers are inoperative or cannot be turned OFF and DTC B1520:49 may be stored.

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.
