I bought my Optima SX in June. I have yet to get anything above 17 mpg with 800 miles on it as of now. Usually get around 14.4 mpg. My dealer tells me that it has to break in and that the period would be 2,500 to 3,000 miles before I start getting good gas mileage. Now I have had many, and I mean many new cars in my life and I have never encountered this problem. Usual break in on most cars is 500 miles. I have almost 800 miles and yes I know I need to give it till at least 1,000 but at the rate I drive getting to 2,500 to 3,000 miles will take several months. Does anyone have any suggestions on this. My dealer basically refused to do anything unless there is a light on. Some one said it sounded like the voltage to the waste gate actuator. Any help would be appreciated.

    I drive mostly highway miles and I was getting 17-19 mpg. Once I hit 950 miles, it shot up to 23 mpg and now that I have 1,800 miles it is averaging 26 mpg. Don't give up on it yet.

    Some of it really depends on how you drive. I have a tendency to use a lot of low end torque and push a lot of fuel down low. So my fuel mileage is around 17. I also have 20"s, etc. So it's to be expected. If you're stock the only thing I would recommend is asking your dealership to kindly reset your ECU and for the first couple hundred miles after it's reset. Drive it relatively reserved. This will teach the ECU to calm it down a bit.

    Ill have to admit when I purchased this car, I too was skeptical. At first I was only getting 17-19 mpg, then somewhere around 2000 +- It started noticing it going up. My best highway mileage across the state has been 34.5 mpg in 100 degree heat with full AC on, 4 passengers and a loaded trunk doing 77-80 mph [eco on]. Not bad at all for 274 hp 4 cylinder. Current city highway average at 9100 miles is 27-29 mpg. [eco on and off]

    I drive with the cruise control on a lot. I get up to 36.5 miles per gallon on the highway with the ECO on. Around town I'm usually in the 23 mpg range. When my wife drives the car it dips down to the 17mpg range. She drives much different than me. You know, she takes off fast, catches up to the car in front of her, brakes because now she's too close. And speeds up to the next red light. It makes a difference...

    I'm looking forward to getting out of my break-in period, but I see I don't have room to complain. I'm averaging about 21 mpg and I've only put in one tank of gas since driving off the dealer lot.

    Well, I have about 2,300 on my SX now, unexpected trip, and I am still getting low MPG about 18 city and 23 hwy. Most of my driving is around town so it is really hard to get really good mileage but I always use the ECO. I do not race to the next light and try not to drive like Speed Racer. But then I get on the freeway and see I am doing 90 and so quickly I really have to watch what I am doing. U always use cruise, even in town when there is a long stretch of road. Also try using the old school way of figuring the MPG by hand and not using what the trip computer says about your mileage. This way you will find out if it is working right or if it is off.

    People have a very different opinions on your tire pressure. I use to work in a front end shop where we did alignments, front end and break work. I was taught that you should always keep your tire pressure about 2 lbs under the max for better mileage and better wear. I don't know if mileage is better but I do know I can get a set of 60K tires to go to 90K.

    Balancing and rotation: Back in those days we just put the tires on with a low powered air gun and made sure they were torqued. Today they use a high powered air gun and attach a torque stick. Every time I got my car back the rotors were warped from over tightening. I really recommend telling whom ever does your balance and rotation to hand tighten your lug nuts and then use a "Torque wrench" to torque them.Do not use a torque stick as they are not as reliable. They will tell you that their way will not cause your rotors to warp but every time they did that that came back warped. Any good mechanic will tell you the same thing. The steel used today isn't as strong as it was back in the day unless you get heavy duty drilled and some like slotted rotors. To the car mfg. it is all about trying to get the better gas mileage so they cut quality. I have done extensive research on this subject on this matter.

    My SX feels like it is really squirrely and seems to drift either way easily. I did up the tire pressure and it seemed to calm down a little. I am taking it in to check the alignment but want to take it to the only guy that is honest about doing it right. He is now working at a Ford dealer...

    I was reading in the owners manual that "If equipped, the ECO light will come on when you are doing well on mileage". Mine is always on. Anyone if know if this is normal? So far I still love my car! Just need better mileage! I don't think I loved a car as much as I love this one!

    Guess you should have gotten the EX instead of turbo...I just got 36 mpg driving from Rochester NY to Boston at 80mph...the non turbo is no slouch either with 200 hp...

    I have an SX Turbo, but I get 24 city / 38 hwy and I don't use the ECO button. The ECO light doesn't come on automatically. You have to turn it on. The ECO button really only works during city driving and only adds on average one mpg. I read this on one of the car mag websites.

    Have the same problem with my 2012 Optima. Had to be towed in, lost power in heavy traffic causing cars to pull off the road as to not hit me, car stalled after running at half power. Has been in for repairs 5 times with no codes this time error code of P2652. KIA made an adjustment to the Turbo, (NOT REPLACING ANY PARTS) They claim the voltage was too high going to the turbo, months ago the voltage as too low and they replaced the alternator??? Bob said what is causing the voltage to change, something in software must be doing that because voltage does no just change.The have not even addressed the GPS going out, The back up camera going out the display going out, the speakers going out, the display warnings saying "Battery Discharged" and the stalling and losing power while driving. The dealership says if there are no codes KIA Corporate won't let them fix anything. I can see many people have this same problem and the computer does not give a code. I just hope nobody gets hurt.

    Funny, my 2011 SX Turbo routinely get 24-27 MPG around town and 35-36 on freeway driving -- I regularly drive to S. Lake Tahoe and get 32MPG -- up the hill and back home. I've been very happy with the mileage -- sometimes I put Chevron injector cleaner into a tank of gas and after that tank my mileage seems to improve a bit --I use 87 octane regular

    Something must be wrong with that car. I have a 2011 turbo with 30K on it. I consistently get 25-30mpg depending on how heavy my foot is and have seen as much as 34 on long trips. Unless you are flooring it at every stoplight, you need to take it back and complain until they figure it out.

    I bought my 2012 SX in late June and still not getting very good mileage, in the teens have hit 20 mpg a time or two. If drive like Speed Racer or very slow and cautious I still get the same mileage. But it is slowly improving... I think...

    I now have 3,200 on it and now the battery drains with in about 6 hours to the point it has to be left on a battery charger for a while as a jump will not work. It's been to the dealer several times and of course they blamed the stereo and alarm add on's. They said the battery was fine. I took it back to the stereo shop, that has one of the highest rating in quality of service and products, and after disconnecting everything installed it still had a draw. They left the alarm items disconnected. Took it back to the dealer and they still can't find the problem. So the regional guy got involved and VOIDED my entire warranty because I had an aftermarket system. (Which is illegal to do here) I was told to put it back to stock or they will do nothing. So now I have to have it all removed for them to find out what is wrong. I had my stereo system installed in June and just now I am having problems and it's the stereo? Ha! Can't be when everything was disconnected it was still pulling a draw!

    I am finding that KIA isn't a very accommodating car company. I also had the same problem with the dealer not giving me a rental or loaner, hadn't found the problem yet was the answer. The same dealer I bought the car from, actually I bought two from them. I see posts from many stating that KIA will not fix anything unless there is a code or obvious problem. Humm... I have an occasional problem with the keys. The sensor will show that the key has left the vehicle when someone gets out of the car. But no code so they won't look.

    At least the stereo shop is working with me on this but they can't work for nothing when KIA can't find the problem. Everything gets removed on Tuesday. Until then I have to disconnect the neg battery cable every time it is going to sit longer than 3 hours. I hope I don't get hurt!

    When they find out that it is the battery or a loose connection or whatever that is their responsibility, they will be getting a piece of my mind and a bill, maybe even media coverage... You don't treat your customers like this KIA! I being yelled at now for buying the KIA over a TOYOTA, I should have listened, life would be more peaceful! LOL

    You must live in the Sacramento area too...

    KIA dealer already mentioned that there might be a problem, you think! I bought this car because of the mileage and then the looks. I don't feel confident taking my car to this dealer as I think the techs are not well trained, maybe limited by KIA. But the 2 other dealers are quite a way from me. I only live 2.5 miles from this dealer so it is convenient. But then I have a lot of issues happening now with my new car... only 3,200 miles... I'm thinking lemons... See my other post...

    Problem resolved with battery. Bad ground on battery cable due to paint, go figure, stereo shop fixed the problem. Yeah!

    You may have got a proverbial LEMON. Take it back as often as possible and don't let them keep labeling it as something different KIA's are great cars but every line has it's shares of lemons

    Help, Please! Have an 2013 optima EX...gas mileage is horrible. I'm lucky to average 19 mpg. I drive like a little old lady. No gunning the engine, using that instant read of mpg like bio-feedback, always use the eco. Last tank, I filled with mid-grade gas - now the readout shows 14.9 mpg. I have a whopping 3,600 miles on it. When I took the car in for oil change, I asked the mechanic - he said the break in period was 5,000. I absolutely love the car, but find myself lying to people about the mpg because I'm embarrassed.

    There IS something wrong with your car. I have the turbo and get combined of 28 week in and week out. I have run the ECO and on a trip the Myrtle Beach down I 95 I got almost 38 MPG going 75 mph almost the whole way. I have 18 inch rims now but got the same with stock equipment. Take it to the dealer until they fix it. Something is definitely wrong with that vehicle. I notice my KIA dealership really sucks twice I have been for minor items. The stock tires leaked air no matter what.

    Over 25k miles on my 2011 SX and mileage remains between 25 and 35mpg depending on how heavy my foot is. On interstates, I cruise 5 - 9mph over the limit.
  20. Kia Optima sxL's Avatar
    In my first Kia Optima sx I almost instantly got the gas mileage it said. Driving on residential roads I usually got around 20 and on the highway I use to get 43!!!!!!!(eco off)That was driving 55 mph the whole entire time and cruising whenever the road sloped down. The 2013 sx I'm driving now I've only gotten 36mpg on the highway. If the dealer isn't doing anything about it go to a news channel or something...maybe they can help. It definitely sounds like theres a problem with your car though.
