Official summary
Service bulletin - Honda has determined that, in some cases, the secondary master cylinder repair campaign conducted since 2011 (S/B GL1800 #20) was not sufficient to prevent the rear brake from dragging. Under certain conditions there is still a possibility that component malfunction within the combined braking system may cause the rear brake to drag. A dragging rear brake increases the risk of a crash and may generate enough heat to cause the rear brake to catch fire.

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.
