I purchased a 2018 Kia Niro Phev EX a week ago. I am concerned if I operate the Niro Phev continually on battery power will the gas engine suffer from non use? If so, is the Niro Phev programmed to automatically force the gas engine to run if it senses that it hasn't been operational for a set number of hours? I asked a couple of Kia service reps but they each said they didn't know. Would it be a good idea to run the gas engine for a day or two at least monthly? Does anyone have an answer to my question? Does anyone else share my concern about non use of the gas engine? I have a very short work commute so I can operate continually in the electric mode. And I can get around our small rural community on electric power only too. I can do three days of local driving on just one electric charge. As it is I never plan to have more than a half tank of gas in my Niro Phev because I'll rarely need to use gasoline. Any information regarding my concern for the gas engine would be appreciated.
