Official summary
Some vehicles may exhibit sparks when the charging cable is connected or disconnected during AC charging. Removing the charging cable while it is energized can cause sparks because the air’s insulation breaks down. To eliminate this concern, the control logic of the PCM has been modified to temporarily stop AC charging upon a door unlock trigger.
Vehicles covered
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.
