I've read numerous other posts about people who are wondering about why the ICE is coming on in different situations (going down a hill for example) but I thought I'd share my experience because I haven't seen anything about my specific case happening. Forgive me if I missed a previous thread in my search. The car is sometimes not using up the full battery charge for my regular commute of 48-55 miles, instead keeping the battery charged at higher levels and using gas Happens in Econ and Normal mode Car did not do this during first ~2 weeks ICE comes on every day before battery is drained. It occurs both when: car is stopped (power flow shows that gas engine is charging battery as seen in picture) and car is moving (power flow shows both gas and battery being used, accelerator is not being pushed hard and the solid blue arc is not there on the bottom) It does use EV for at least the majority of the drive I brought it into my dealership and asked about this and was told simply that the car cannot operate without gas and that the car decides when to use the ICE. I found it particularly strange that the engine would come on to recharge the battery when it is showing full capacity and the car is at a stop, but they could not explain this to me. Just said it was normal. Has anyone else had similar experiences?
