Official summary
Some customers may experience that the fuel lid and charge lid do not lock or unlock during door lock/unlock operation. This is caused by: Improper dimensional accuracy of the lid actuator lock mechanism Incomplete control logic in the R-ESU software To eliminate this concern: The mold design of the lid actuator was modified. The control software of the R-ESU was revised.

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.
