Official summary
TSB: Battery Electric Vehicles (BEVs) receive electricity via an external power source that is stored in the BEV traction battery. When the electric vehicle will not be used for a period of 30 days or more, the traction battery will self-discharge, reducing vehicle range. To prevent the battery from fully discharging it is necessary to maintain the charge level of the traction battery

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.
