I finally wore down the tires that came with my 2012 volt and got a new set yesterday. I didn't go to the chevy dealer since I figured it was just tires like any other car and it saved me nearly an hour of driving. Last night when my wife was out running errands the Service High Voltage Charging System error showed up and now the car won't charge. Is there anything special that needs to be done when the tires are changed? Has anyone else had this happen to them?
