Official summary
A potential issue has been identified on a limited number of vehicles within the listed Affected Vehicle Range where if the engine coolant temperature is below 70° Celsius (158° Fahrenheit) in over-run, the engine runs using the incorrect level of mapping. In this region, the map is too retarded and may cause misfires which overheat the catalytic converter, resulting in damage.

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.
