2014 First Problem P1F58 CEL

Hi all-

My first problem with my 2014 Volt. It just turned 30,000 and I charge on 240. Check engine light turned on after unplugging it.
Any ideas of what this code from Onstar means, or has anyone else experienced this code?

The Lithium-Ion Battery is not performing as expected. An issue has been detected in the Onboard Charging System which manages your vehicles battery pack charge level.

The car is performing fine and is charging.

The EVSE handle has a circuit in handle, so that when one presses the handle to remove it, this signals the car and the EVSE charger to turn off the main power. Turning off the high voltage so the connectors are not removed with current going to through them when removed causing an arc. So if the charging handle is removed too quickly the high voltage could be removed prior to the car recognizing the handle depress.
