Poor Fuel Mileage 2006 Hyundai Sonata 2.4 motor

Two weeks ago I bought an 06 Sonata (43,000 miles on the car) with 2.4 motor with auto transmission. My city gas mileage is 12-13 mpg and 23 highway mpg.

I called Hyundai USA there is no noted vehicle problems on this model or recalls.

I have to take the car to my local dealer and have it checked out.
Has anyone ever heard of this and is there a solution to the poor gas mileage?

    I have an 06 manual with 35 K with the same problem, 20 MPG city/25 MPG hwy instead of 24/34. Mine needs an allignment and tires are cheap. I'll check an air filter. Share your progress on fixing it.

I don't know from where you bought the car but do you feel certain that typical causes such as fouled plugs or clogged air filters are not at fault?
Most dealers, even the shlocks don't normally skimp on the simple stuff but who knows about a private source?
That does seem low, especially the city numbers. I don't think Hyundai is any leader in gas mileage but they are better than what you are getting.

I have a 2006 Hyundai Accent GS. I have noticed i am using excessive amounts of fuel ( 1/8 tank to go 5 blocks) I dont have a leak in my tank either. What would be causing this??

The 2 most common causes ( other than driving habits) for poor fuel mileage are dirty air filter and low air pressure in the tires. Make sure to replace the air filter at least every 15K miles and keep tires properly inflated. After that, you could need new spark plugs, wires, ect. depending on vehicle mileage.

At what mileage do spark plugs in 2006 hyundai sonata need to be changed?

Typically at 100k miles. If the car is used for mostly city driving and in severe climate area's it may be necessary to change them as early as 60k. Make sure to use OEM plugs. Also dont forget to change the spark plug wires, they wear out too!

At what mileage do you change a timing belt in a 2007 sonata, 99% of mileage is highway.

Most car manufacturers recommend replacing timing belts after 60,000 miles. I have seen cars go 200,000 on a timing belt. But I wouldn't recommend that. Personally, that Max I would go, even if 99% of your driving is highway, is 80,000 miles. I'm not 100% sure about the sonata, but if it is front wheel drive and your replacing the timing belt, think about replacing the water pump at the same time. That is always good practice to remember.
