I, too have a `2012` Impreza
I, too have a `2012` Impreza Sport and am really disappointed with the gas mileage. After 3500 miles, I'm stil getting less than 22 miles in combined driving; even when that includes more than 75% highway miles for the tank.
I traded a Honda CR-v AWD, which got better mileage...not much but better. I previously had 4 Outbacks which all got slightly better gas mileage.
My Subaru's have always been "higher maintenance" than Toyota's or Honda's. Was really looking forward to a better gas mileage AWD, but that looks like it isn't gonna happen.
What a disappointment.
