Emissions check engine light
After getting a few messages on the screen saying that the fuel door was not closed when it was, I now have a check engine light and OnStar reported a problem with the emissions system. Anybody heard of this before? I have an appointment with the dealer but they want me to leave the car. Not keen to do so.

Tell them what ever excuse you need to, but I would not leave my car. I have found if you wait the service is much quicker. The service writer gets tired of seeing you waiting and asking them how everything is going. If this was a major repair you would have to leave your car but not for your problem.

The C7 doesn't have a fuel door, but if the flap doesn't close all the way, sealing the fuel system, the system will generate a CEL for that. If that's all it is, it will reset once the flap is closed correctly and you drive it a few times.
I'd go to a gas station, stick the nozzle in and remove it a couple of times, then drive it for a few days, and hope it clears on its own.
