The other day I was driving on the highway when out of the blue the battery started to discharge and the service charging system warning message on my screen with the battery light came on . The engine is running normally but idles alittle higher .I checked the battery (which is about 1.5 yrs old) at idle the voltage is about 12.5 volts and when I started it up it was 14.5 volts . After awhile all the warnings cleared up. Then today it started to discharge on the highway and back to all the messages. I need help identifying the issue the alternator the battery or the ecm/bcm...thanks
