"this bulletin announces availability of reprogramming files to optimize transmission control module (tcm) operation and address the following customer concerns: engine rpm flare (sharp rpm increase when cvt downshifts ) when using cruise control on uphill grades cancellation of cruise control as a result of rpm flare (driver must reset desired vehicle speed).

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.
