I have a 2017 and I agree with you that it is hungry on gas. Well what can you expect with a 2.5 tons vehicle. It will sip gas specially in city driving. One thing that I will never like and I can repeat it hundred of times is the cheap resolution rear camera. I even find these camera dangerous because of the poor quality image you get. No contrast, very fuzzy picture from far away. Otherwise I like it even if this vehicle is poor in winter to warm up.
