Official summary
Dealer Letter: May 7, 2018 The condition has been clarified. Special Service Campaign J0D is SUSPENDED. An Electronic Control Unit (ECU) in the subject vehicles has improper programming that could lead a component in the Continuously Variable Transmission (CVT) to unnecessarily cycle and experience abnormal wear. If this component becomes damaged, the Malfunction Indicator Lamp (MIL) may illuminate in the instrument cluster and the vehicle could experience a reduction of speed. After reaching a pre-determined gear ratio, the vehicle can be operated up to approximately 37 mph.

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.
