Thanks you for your suggestion. However, this car did get the excellent mpg all last winter,and didn't change until this Fall when it steadily dropped . However, I will check it out.I agree with you about the BS which I was given at the dealership.

#922 of 930 First long trip by backy

Apr 21, 2013 (3:12 pm)

Finally got to take my wife's 5-month-old Sonata GLS on a trip longer than ~10 miles. Car has 3000 miles on it. Drove a round trip of 180 miles, most of it 4-lane highway with cruise set between 65-67. Only had to pass a couple of times. Some in-town driving in the middle. First day was clear, mid-30s, light wind. When I exited for my destination, the mpg meter read 38.5, nearly all nonstop highway. When I got on the highway for the return trip, the in-town driving had dropped the average mpg to 35.8. But although I drove in snow/rain and a 20 mph headwind on the way back, the overall mpg ended up at 36.5. With a little warmer temperatures, I might do a bit better than that, but I'm happy with the results, even allowing for some error in the trip computer. It's at least 10% better than I got with my 2007 GLS, and that car had 162 hp vs. 198 on the new car.

#923 of 930 First Tank of Gas by reagan_a

I got my 2.4L Auto Sonata GLS last week and managed to use up my first tank of gas yesterday. I got in 330 miles on the odometer at the time and refilled 17.7 gal (roughly 18 mpg for 30% city 70% highway). This is incredibly frustrating. Does anyone have any tips or solutions as to why this might be this low? I am generally conservative with my acceleration and braking, trying to get the most out my car. I live in the Northeast Philadelphia, which is nowhere near as hectic in traffic as our center city. So it doesn't make sense. I will greatly appreciate any input!

I understand your frustration. I have found that in order to get more accurate readings, I have to reset the trip button for each trip. Even though my mpg gage shows 40 on open highway driving, I don't think it is accurate. It seems to me that if the gage shows 550 upon filling the tank, and the tank holds 18 gallons, it would be more accurate to divide 550 by 18 to get the correct average mileage, which is way below the mileage claimed by the company. I have found this mileage thing to be the most annoying aspect of this car, and I am very disappointed with the car for this reason.

No help will be enough. They lie through their teeth. Keep it by hand. The computer is invalid. I get barely over 30 mpg on a straight highway run. Lower 20s local. It drops like a rock going up hills. Me too. The car's fine. The MPG the downfall. The liar who sold me the car went back to selling subprime mortgages. Less sleezy.

Do not use the ECO Boost button in local driving - it makes the engine work harder. Only use it when you're on the open highway. I have seen an improvement since I've started using it this way - instead of using it at all times.

#927 of 930 Thanks for the reply by reagan_a

Thanks for the quick reply guys. I will def try the ECO boost button recommendation and keep it off in local. Hunday12, I wish my fuel remaining gauge showed 550 miles after filling up. It showed me 368 after filling up, and I didn't even get that much out of it (only got 330 miles). Dgolly, I tried talking to my dealership and hyundai, but they both told me that its because the car haven't been broken in. I think they're trying to stall me because they're afraid I might ask for an exchange or something (not even sure if thats possible with me already putting in nearly 400 miles so far). My cousin who bought the exact same model gets 23 local and 35 highway. I guess some of us just happen to drawn up the few bad ones of the batch. Its also funny how they're reimbursing almost every other 2012/2013 models for low mpg, except the sonata.

#928 of 930 Getting 27 mixed and 34 on only highway by michellej87

I have 2013 Sonata with 5k miles on it.
 
I have been using eco boost all the time thinking it would choose mpg-friendly acceleration in city. May be I am wrong. I should try turning it off.
 
Overall I am getting 28 mpg but I drive mostly highway (2 miles to get on and off the highway and 15 miles on highway at 65-75mph). I drive well never using accelerator when not needed and turn AC off unless it is super hot.
 
When I went on longer trip 60 miles I got 34+ mph.
 
Overall the car is meeting my expectations but I expect more.

How can you expect more when it's meeting your expectations?

It's rated at 28 overall and you're getting 28 overall. Not sure why you'd expect more.
