It's not that low. There are so many things that affect mileage. I drive my 2006 Civic Hybrid a mix of city and highway, probably 70% highway and 30% city. My Mom also has a 2006 Hybrid,but she drives mostly within the small town she lives in. I get better mileage than she does. And the colder it is the mileage goes down. I was getting mid 30's to low forties in winter. But now that it's warmer I've been getting low 40's to low 50's. And your car is really so brand new, just be patient, the mileage will increase!
