Owner report 11129500 · 2018-09-14 (September 14, 2018)

THE CLARITY PHEV IS INCOMPATIBLE WITH PUBLIC CHARGING STATIONS (E.G. CHARGEPOINT) THAT FEATURE DUAL CHARGING PORTS AND AN ENERGY MANAGEMENT CONTROLLER (EMC). THE VEHICLE'S ONBOARD CHARGER WILL SHUT OFF WHEN IT SENSES THE CHARGING STATION'S EMC IS ACTIVATED WHEN BOTH PORTS ARE ENGAGED FOR SIMULTANEOUS CHARGING. MULTIPLE FAILED ATTEMPTS TO RESTART CHARGING WILL RESULT IN A "TOTAL SYSTEM FAILURE" WARNING FROM THE INSTRUMENT PANEL CAUSING THE VEHICLE TO NOT START AND DRIVE.
