Is My EV Working Correctly?

The battery on my Limited Hybrid has not been charging as much as it did a few days ago. At low speeds, EV mode would come on most of the time, now it doesn’t come on as often. My mpg’s are consistently lower. I live in the Phoenix area and it is 100 degrees here. Is there an issue with my battery or the way the hybrid system is managing the battery? It will only get hotter during the next few months and still want to be getting 40+ mpg. Is this an issue I need checked out? When we check the battery level, it is at 3/8 bars and we are doing a lot of around town (suburban) driving. It is not recharging as we would have expected.

It could well be the temperature. AC being driven by electric motor would be a load on the traction battery.

Engine coolant temp., speed, traction battery State of charge are all factors in when the car would use EV Mode.

Its a new car give it some time to break in, are you using the ac its electric, radiator fan running more, heater motor on, keep monitoring the fuel mileage and give yourself some time to get used to the Suv. I drive mine in normal mode and forget it. 100 degree weather isn't an ideal temperature.

Also, if you haven't yet, read section 4-6 in the Owners Manual, "Hybrid vehicle driving tips". Especially useful might be the part about gently braking over a longer distance to more efficiently recharge the battery.
