Official summary
Service Bulletin - Due to the possibility of early deterioration of the Continuous Variable Transmission (CVT) drive belt, American Honda is extending the warranty coverage on these CVT models to 7 years from the original date of purchase or 150,000 miles, whichever comes first. If the PCM software was previously updated in service bulletin 21-046, Product Update: 2016-20 HR-V Software Update and CVT Inspection, the warranty extension applies, since the CVT primary drive belt is now a OBD-monitored part due to the addition of DTC P271E.
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.
