Hi! New Touring owner! Love this car!! Kind of struggling to understand it. Some days MPG is great, other days not so much even though I try and drive the same way. It migth just be me, but I notice that on some days the HV battery doesn't charge very fast and seems to deplete quickly. I try and use normal in stop/go traffic and then ECON on the highway. I do use the paddles every time I stop. I do use sport mode occasionally. Am I doing something wrong?
