Well after 2,800 miles, the "Check Engine Light" comes on. I hit the button and speak to OnStar, they pull the code and tell me that it's "Fast Charging System Fault".
So, since I have the Fast Charging/DC charging installed (but never used yet), I ask does that mean the on-board charger which works off 120v and 240v or only the DC Fast charging. They and the specialist couldn't tell me. So, it's at the dealer now.
