Hey Andrew,
That’s a bummer about your Volt’s fuel economy! 😔 A few things popped into my head when I read your post. First off, could it be your driving style? I mean, if you’ve been flooring it more often or slamming on the brakes, that can definitely guzzle up more gas. Just a thought!
Also, how much have you been using the AC? Blasting the AC, especially on short trips, can really drain your MPGs.
And speaking of short trips, have you been doing a lot of those recently? If so, that could be another culprit. The engine doesn’t have enough time to get warmed up and running efficiently on those quick jaunts.
BTW, I’m in Fremont and looking for a first car for my son. If you’re serious about selling, maybe we could take it to the GM dealer here for a once-over? And to keep things easy, we could use a standard bill of sale like this one: https://lawrina.org/templates/bill-of-sale/car/
Just throwing it out there! Let me know what you think.
