My 2023 PHEV no longer runs in only EV mode even in the EV/Smart and full charge. Within a minute of starting, in EV/Smart mode, the engine starts and will run about a minute or two, then EV only kicks in. I've watched the display on the dash and it indicates, during that time, the engine is charging the battery and the battery is driving the wheels. This recently started to occur. All summer the car ran as expected, since November this pattern described above began. Any suggestions to get me back to full time EV on short drives and full battery?
