After running Maintenance of gas engine due to not driving enough, engine will not return to electric mode and Hold is not an option!

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. When your Volt doesn't switch back to electric mode, it's often due to the car's maintenance mode needing to clear, which typically takes a full engine warm-up cycle. It sounds like your Volt may have completed engine maintenance mode, but it also may need to complete fuel maintenance mode depending on how long it has been since your last fill-up. Drive the vehicle until the engine has fully warmed up, then try shutting off and restarting to prompt the switch. If this doesn't work, the issue might be with the charging system or a battery management software glitch, which a scan tool at a certified shop could diagnose. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
