I am the original owner of a 2012 Volt. It has 104,000 miles on it. Twice in the past month I have received the following message: "Propulsion Power Reduced". In both instances, my battery had been depleted and had been running on gas. I turned the car off and after turning the car back on and driving a short distance I got this message. Both times temperatures were sub freezing perhaps even close to 0 F (I can't exactly recall). Even though I accelerated slowly and was driving in town and at slow speeds, the gas generator was racing very fast. When I arrived home (about 1 mile drive), I could smell that "hot engine" smell.
Could it be that the car is overusing the battery and when I start it back up the generator needs to recharge to the minimum battery level? Or perhaps the cold reduced the battery capacity readings as it sat and needed to recharge up to the minimum? Hopefully I'm not looking at a major problem here?
Has anyone else had this issue or can anyone explain why this might be happening?
