Official summary

Service Update Bulletin (Labor Codes Added). Certain vehicles may have a condition where the engine control module (ECM) software allows the Auto Stop to occur at a state of charge below 65%. Auto Stop is supposed to be inhibited at 65% to protect against excessive battery wear and discharge. Dealers are to reprogram the ECM.

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.
