Hi and here I am looking for answers. I bought the Volt recently with only 15k miles. Put about 2k miles on it already with no issues. When I unplugged the charger today the CEL was on. I checked the gas cap, no help and then drove it 42 mi (batt and some ICE) with no problems. Lite is still on. Was hoping the light would go out but so far not. Will check for codes after I use it today again. I signed up for Onstar hoping they could diagnose the problem (don't know if they have that capability)
Firstly, welcome to our Volt family! It’s always nice when we can convert somebody from traditional cars into electric models.
With the necessary OnStar subscription, you are able to push the blue OnStar button in your vehicle and have them run a preliminary diagnosis on your vehicle. If they are unable to pull any codes and your CEL light is still on, I suggest we have your Volt taken into your dealership for further analysis.
I’m always here to help, and I can certainly reach out to your dealership on your behalf to help schedule an appointment if necessary. If you would like my assistance in this way, please send me a private message with your VIN, contact information, current mileage and the name of your preferred dealership.
