After charging vehicle using L2 charger, (max 7kw) vehicle threw two error messages on screen. 1) âcheck electrical system❠& 2) âstop vehicle and check power supply❠Using an OBDII reader, the car provided error code P1A9096. I also noticed the car stopped charging the 12V battery as the 12V state of charge was down to 22%. I towed it to the dealer and they are currently working on diagnosing the issue.
