We have fairly frequent power outages where I live. I'm going on vacation for 2 weeks. Should I leave my 2013 Volt plugged in while I'm gone? What if the power goes out while I'm away?

There is also a service modem that allows your Volt to be powered off entirely and disconnects the 12v for really long durationsshould be fine..if you didnt read this ...here you can >www.chevrolet.com/content/dam/Chevrolet/northamerica/usa/nscwebsite /en/Home/Ownership/Manuals_and_Videos/02_pdf/2k13volt.pdf

Short answer: NEVER leave your Volt plugged in at all times, just to charge overnight. The best answer is to deplete the battery to about half, and it can go for upwards of a year that way. I leave my 2017 Volt parked and unused for 6 months at a time, with zero depletion. Lithium Ion batteries degrade (relatively) quickly at full charge, or zero charge. They store wonderfully for years at 1/2 to 2/3 charge. My problem, and maybe yours to if you have an older car, is that the 12V system battery (same lead-acid battery that most cars use to start the engine with) degrades in MONTHS without a charger, and much quicker if at 80 degrees or more. So, for you, 2 weeks keep off the charger and deplete the battery to half for best life.
