Hi,
I have Problems/Issues, Driver Warnings or DTCs - Chevy Volt 2013 showing Service Battery Charging System and the red battery light stays on as displayed on the dashboard indicator error messages.
The 12volts external battery is dead. When i charged it ams start the car but after driving the battery ran down again. Voltmeter showed 11.5v so I bought a new battery and the problems remain.
Please note that the car is out of warranty and currently in Abuja where there is no onstar service.
Kindly help on how to fix this
