Official summary
Owner Notification Letter - Honda is conducting a product update to your 2016-20 HR-V. The current continuously variable transmission (CVT) software does not properly monitor internal fluid pressure and detect early CVT belt failure. This can possibly cause the vehicle not to move when accelerating. Honda is providing a product update with new CVT software to fix this issue.
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.
