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.
