Service bulletin SV-ZMC-020-423

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

Long-Term Storage Mode Firmware Update Service Campaign - Zero Motorcycles has determined that the battery management system (BMS) may not hibernate in model year 2017 and newer Zero SDS and Zero XMX platform motorcycles when they are stored at states of charge (SOC) less than 30%. Because the BMS does not hibernate, the power pack's SOC may drop more rapidly than desired and may reach an irrecoverable level within a 30-day period. This Long-Term Storage Mode Firmware issue has been corrected in Version 30 of the Main Brain Board (MBB) firmware and Version 37 of the BMS firmware for these motorcycles. Owners should either use the Zero Motorcycles Mobile Application to update the firmware of their motorcycles to the newest version, or they should take their motorcycles to their dealer to have them updated.
