With very conservative driving, lights off and no other electrical draw aside from the radio, I only get 13.5 to 13.8kWh on the battery until the ICE kicks in. I read in the forum of people getting 14.1 to 14.4. It is a 2017 LT with 22K. It was this way when I bought it at 15K. Should I be concerned? With my driving style and terrain, I can achieve 77 miles in the summer (very little AC usage).
