Official summary
echnical Service AUDIO VOLUME NOT RESTORED AFTER MSA STOP, ENTRY HEAD UNIT. Volume of audio system (when set to near maximum) is reduced when Auto Start-Stop (MSA) stop occurs and is not restored upon automatic engine restart. This is normal system behavior - serves to protect the head unit, battery drain and avoidance of incremental leaps in the loudness. The loudness is reduced to 2/3 of maximum and is not restored. Note: Air conditioning output is also reduced upon MSA stop and is not restored for similar reasons.

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.
