Service Bulletin/Repair Instructions
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.

Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
