Service bulletin SFCC_MAR2024_25
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
