 Really only 285 miles per tank of gas!!! 30 mpg barely. I am driving 60/40% hwy/city and im not even getting 300 miles per tank. I took it into the dealer and was told that they "hooked it up" and there were no codes showing any problems. I drive speeds varying from 45-75mph....more closer to 75mph. So tell me what i must be doing wrong??? When my wife drives the same as i do (if not worse) and she has the sedan model. She gets close 340 miles per tank of gas. I was told by the dealership (Colonial Hyundai of Downingtown, PA) that it was the way i drive not my car. Should have stuck with an american made car!!
