Official summary

A concern has been identified where the 48V Mild Hybrid Electric Vehicle (MHEV) battery enters an offline state and no longer communicates or functions as intended. This can result in illumination of the Malfunction Indicator Lamp (MIL), loss of start/stop functionality and no communication during diagnostic sessions. A software update to the Battery Energy Control Module (BECM) is required.

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.
