Its great having both. EV’s are so great for daily driving, no ICE car can match the smoothness and simplicity of driving an EV. I bought a PHEV with limited range recently and I’m really regretting not waiting a little longer and just buying an EV, the EV mode is so good.
Is it just turning on, on its own or is it when you press the gas? I know in mine even if the battery is charged you can only press the gas a little before the engine kicks on. Can’t think of any other reason why it would do that.
