Gas mileage far below promised. the 2004 kia sedona lx was posted as 16-22 mpg. we are averaging 11 mpg hwy/city. it has been to the dealer twice, the second time there were parts replaced like airflow sensors. this did not correct the problem. our dealer has worked with us well, but with gas prices the way they are, the cost to operate the vehicle is much more than advertised. i have talked to others who own the sedona as well, some are averaging over the 20mpg, while others are like myself, 10-11 mpg.*ak
