I have the Niro EV Premium. Overall, I am super happy with it! Since I just purchased it in late October, and live in northern California (Sacramento area), I really have not needed to use either the AC or heat yet. So far the ventilated seats have been sufficient on the warm days, and the heated seats and heated steering wheel have been sufficient on the cooler days. I almost always have the front windshield defogger on while driving, but without turning on the AC or heat, and without the temperature set to auto. Intermittently the AC and/or heat will activate on it's own. I usually notice because the range has a sudden drop of about 10-25 miles, so I look over at the middle console, and sure enough the AC and/or heat will be turned on. Has anyone else had this issue? Is there some type of function that would make the AC and/or heat activate on it's own? If so, does anyone know how to make it stop? Thanks in advance for the help!
