i bought the car oct 12 11 with a full tank of gas and approx 6500 km.
1 full tank is 51.8 liters. i drove this car,easy on the gas pedal, city driving ony, untill the gas indicater was just below the last mark. i got 288 km.
car is rated to 573 km......9l/100km. seems i got 5.5km/liter. 49.5km/9liters,a little better than my previous figures. But still not what i was told to expect. the road condtions and weather were good.

well its obvious you didn't figure it out right, 52L is the total capacity of the fuel tank not what you used, other wise you would have been stranded and out of gas! It's quite possible you had another 50-75 km left in the tank before it would be empty and also did the low fuel light come on? How much fuel did you put in the tank to cover the 288 km? Is it a 2.0L or 2.4L?
I would run a few tank full recording the amount of litres put in the tank (till the pump shuts off) and record the km covered. You don't know how full the tank was when you bought it as you didn't fill it. Don't go off a fuel gauge as being dead accurate, they never are.

the person i bought the car off filled the tank, till it clicked off,it was full,as i was there.i ran the car with the low indicater light on for 30 km as i wanted to see how many km i could get. the car is a 2.0. it is rated at 573 km per tank,city driving. 288 plus 50(reserve) is 338 km, 235 km short of my expectations,a big difference.
i visited kia today for an oil change,inquired about this issue,answer...the car needs to broken in..up to 12 or 13000km(service dept ans)8 or 9000 (sales dept ans). I really like the car and will keep track of my fuel milage and make updates. any sugg to improve my milage apprec.

you still didn't say how much fuel it took to fill it up after driving this 338 km?
The fuel guide figures are a guide to compare various vehicles, it does not necessary mean that you will get it, it clearly states that. The are run under laboratory control conditions so its always consistent. You need to run a few tank fulls recording the mileage covered and the fuel it took to cover that distance.
You are still comparing the range on the vehicle on a fuel tank that is run till empty - that does not happen! Is it a manual or automatic?

don't believe the [profanity removed] from your dealer, your Kia requires no extended breakin as stated in the owner's manual, my Kia was getting close to EPA hwy rating after 2 tanks, and improvement over the next 30K was minimal.
city FE can be affected by many factors:
cold weather, especially short trips, it can be up to 50% worse
traffic pattern, rush hour, downtown...etc
try testing on a longer trip, do not top up when filling up, try to do it at the same pump same gas station if possible for better accuracy.
i repeat, do not believe your dealer, you are doing the right thing by posting in this forum.

I have an identical fuel consumption problem.
I bought a 2011 Forte 5 EX (2.0L, 6-speed) in July 2011.
For the first 5 tank fill-ups (45-46 liters, read at the pump, I usually fill up as soon as the gas light turns on) I was averaging 500-520 km (city driving and air conditioning running, echo light on most of the time).
Then ... in September (still very good weather conditions in Toronto, but no need for air conditioning) I noticed that I could only get 400 km out of the 45 liter fill-up. And now I average 380 km (5 fill-ups so far).
I asked the question at the KIA dealer this week, as I was going to get the first oil & lub (odometer 4000 km, mostly city driving, echo light always on), and I was told that the engine was wearing out and that it's normal to see an increase in consumption. I thought it was bullshit (from 500+ down to 380km ... come on).
What I noticed though, is that when driving on a flat surface at about 50 km/h, no acceleration, the transmission shift to the 5th gear (!) and the engine runs at 1000 rpm. Is that really gas efficient ???
I heard that parameters of the transmission control module can be adjusted to improve gas consumption on some other cars. Can it be done on the Kia Forte 5 and how?

The fuel consumption should be reduced, not increased as it breaks in for the first few thousand km, so that part from the dealer is nonsense. Maybe a sensor is going bad, and the fuel mixture is wrong, or something like that? It does not sound right.
My 2010 Forte 5-speed auto will shift down to 5th gear so as to run around 1200 rpm at 40 mph (70 km/h), but I have never seen it down to 1000 rpm. It should be gas efficient at that speed though.

you only managed to drive 4000km in 5 months, probably lots of short trips?
compounded by the cold weather in November, i think what you see is normal.

I GET 16L/100K. CITY DRIVING WITH A VERY LIGHT FOOT. POSTED THIS ON THE KIA SITE ON FB AND NEVER GOT A REPLY. ASKED SALES DEPT THEY SAID CAR NEEDS 8 TO 9000 KM TO B BROKE IN, I THEN WENT TO THE PARTS DEPT, AS I WAS THERE TO GET MY 60 DOLLAR OIL CHANGE,AND ASKED THEM THE SAME QUESTION AND THEY TOLD ME THE CAR NEEDED 12,000 TO 13,000 KM TO B BROKE IN. THEY HAVE MY 25,000 NOW SO TO BAD FOR ME. STUCK WITH IT NOW.

I am having the same problems. Driving from IL to St. Louis, I only got 26 mpg, going 70, using the heat only about a third of the time. I haven't even broken 30 mpg one time. I also previously had a '02 Elantra GT that I loved to death, but it died in a fender bender against a much larger car to my sadness. I have 10k miles on the car, and if anything, the fuel economy has gotten worse, not better. I have the 2.0 L automatic, and the 36 mpg highway rating seems like a filthy filthy lie to me.
If anyone has any luck having anything done in the shop to increase fuel economy, please post. I'm going to be keeping quite a careful log and be looking into lemon laws.
