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.

Same here. I actually just pulled up next to a guy with another 2.0L 5-door EX and he said the same thing. 26mpg is the absolute most seen by either of us. I do 80% highway driving which makes this even more ridiculous. It's actual got me looking into swap-a-lease.com. I tried talking to the people at the service department and all I got was shoulder-shrugs and "yeah, we've been hearing that a lot from people". If anyone comes up with something, let the rest of us know!
#43 of 66 KIA Announcement regarding MPG-WHY ISN"T FORTE INCLUDED?
Nov 02, 2012 (5:57 am)
I am pretty furious. My experience with my 2012 Forte Sx has been less than optimal to date. I liked the "get up and go" that the car had, and enjoy it's look. My problem: by my one year anniversary I have lost the love. There are spots on the hood where you can see white underneath the red paint, suggesting that peeling is on it's way. Dealer says NOT COVERED. SORRY...and to reassure me saide "HONDA AND TOYOTA ARE HAVING SIMILAR ISSUES." That really made me feel better about it!
It has the loud rhythmic engine noise that I have had looked at 3 times now, each time being told "it is normal."....
and now this.....
My car gets about 18 mph city. That is SIGNIFICANTLY less than the 23 that the KIA specs list. SO HOW COME I'm not going to get the benefit that other KIA owners are going to get related to the KIA MPG fraud?
As you can tell...I am a little HOT right now regarding this.
Sorry...didn't get much sleep last night.

If you are a Hyundai or Kia owner and have a reaction to the company’s announcement today re: EPA fuel economy ratings, please email PRedmunds.com today to talk with a reporter.

I can understand your frustration dealing with the (no)service department of a dealer.
In general, Kia has made huge improvement over the quality of their cars in the last few years, but unfortunately, the service managers/techinians at the dealers level are not keeping up.

Yes. I have now had my 2012 KIA Forte 5 EX for seven months, and have been shocked at the horrible mileage. I held off, as I was waiting to see how it "broke in." And in-spite of the salesman saying it gets better than advertised; I discounted that, and went with the stickered average. That being the case, and doing 90% highway driving on a 20 mile commute, I was expecting between 31-33 combined, and 34-36 hwy. I am now at 9k miles, and the engine is broke in with no mileage gains over new. I am getting a low of 24 and never better than 29, with an average of 28. I have tried ECO on and ECO off with no difference. I have filled up, and driven our Legacy Parkway on cruise at 55 both directions (40 mile RT), and I got 29.
In a world where we all know every car dealer is a liar, and the government sanctions their lies with economy stickers, our situations are not surprising. As I read more and more of these stories, it is starting to push me to find legal counsel and push for a class action on a contingency, and with any luck we can get them to respond like Hyundai did over their incorrectly advertised mileage. My son recently received a letter from Hyundai apologizing for the incorrectly reported mileage, and told him to take it in to certify mileage and they would cut him a check. They will continue to do this for the time he owns the car, as long as the mileage is certified, and they will do so at the rate at the rate at which he pays for gas. They are offering him a check at the rate of 1 or 2 mpg depending on the vehicle type.
