The hazard

Issue: On certain vehicles, the DC-DC converter may shut down in cold temperatures due to a software error. If this happens, the 12-V battery would stop charging and a warning light would turn on in the instrument cluster. If you continue to drive with this warning on, the 12-V battery can discharge and cause a loss of power to the wheels. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Corrective Actions: Honda will notify owners by mail and instruct you to take your vehicle to a dealer to update the Power Converter Unit (PCU) software.
