Service High Voltage Charging System - Out of warranty

Got in my 2013 volt this morning to go to work, go the "service high voltage charging system" error code. What exactly does it mean? New charger needed?

Battery coolant level is fine.

I'm at 145k miles so I'm guessing out of warranty or would this be included on the 150k voltec warranty?

I have only had the car for a couple months
