battery heating

  1. 2011 - Suspect the Battery Heater isn't working

    Problems, Driver Warnings or DTCs - Chevy Volt
    My 2011 volt just started running only on gas - even for an hour long commute. There's no engine lights/warnings, and I did not get the ERDTT warning. I'm taking it in for service later today. Has anyone run into this? The 12v battery is less that 1 year old, and I've recently has the coolant...
