I was on my first really long road trip (central Florida to northern SC and back) and the CEL popped just past the GA/SC line as I was headed back to Orlando on I-95.

The OnStart text read:

Diagnostic Alert: Service the emissions system in your 2017 Volt within 7 days. Txt STOP to cancel.
The My Chevy website has the following "Additional Maintenance Item":

02/26/2017 12:17PM The powertrain system has detected a malfunction related to the engine fuel control system. Engine performance may be affected.
It's odd that the Vehicle Systems portion of the website indicates that Emission Controls Systems are fine.

The car is running fine, perhaps with slightly worse ICE milage, but no surging or backfires.

Hopefully it's just an O2 sensor.

Sounds like it could be a P2097 issue, check the problems section for a couple of "sticky" strings on this issue. Did you have the most up to date software installed? There have been several recalls, some specifically covering this issue.

You can have an emission related issue and the engine can seem to run fine. Emission related codes are for issues that would cause the vehicle to fail an emission test, not a driveability issue.

I'm up-to-date on software ... I had the recall performed back in December.

ETA: I don't have a recall notice for P2097, but all other recalls have been performed.

Check your gas cap seal. An improper sealed fuel tank is the most common cause of emissions related error code on any car.
I was three quarters of the way through a tank when the CEL popped. I pulled over for gas shortly thereafter and made double sure the cap was tight.

Thanks for the suggestion though.

But still, get that car in as soon as possible and demand an efficient loaner. Cars with emissions system problems shouldn't be driven.
(Exception would be if you know you'd be driving all-electric for a while. Obviously, a non-running engine isn't going to be producing a lot of pollution ...)

I have an appointment for this coming Saturday morning.

Good call ... it was P2097 (Recall Drive Motor Power Inverter Module).

They also reprogrammed the front camera referencing Service Bulletin N162039570.
