I wish you the best of luck in pin-pointing the problem. I had a 2002 Santa Fe AWD with a 2.7L v6 that did really well on gas mileage. I traded it for a 2006 Santa Fe AWD with a 3.5L v6 and it was TERRIBLE. My 2002 got 27 MPG on the highway with A/C on low and cruise set to 70 MPH int he summer. My 2006 NEVER got more than 20 MPG along the same drive and conditions. They just laughed and told me that it was normal for that powertrain. But the sticker on the 2006 said it should have gotten better. I loved that SUV too but finally sold it last Spring with only 25k miles on it because of the lousy gas mileage.
I'm still a big fan of Hyundai. My 2002 Santa Fe did great! And my 2005 Elantra consistently gives me 30 MPG in mixed driving with 140k miles on it.
You might ask them to check the oxygen sensors. Those don't always send a code when they are acting up. And they can definitely affect you gas mileage. There are a lot of electronics on the engines these days.

I agree... BUT- you would have to stay with the oem tires - any other tire will have a different rotation per mile and may change the mpg for better or for worse... and this is definitely more significant if you change from the oem tire size - there are options that will fit that are not the oem size...

My 2007 SF AWD V6 (3.3 I think) is getting similar terrible gas mileage averaging 15 in town & maybe 18 hwy. We are incredibly disappointed. I love my SF except for this. Is there anything that can be done?

Well....we believe we were "duped" by the dealer. The sticker on the car was extremely misleaading! A Honda Civic is the only solution. We've been working with multiple dealers for almost a year with little or no improvement. We're getting 19-20 HWY, which is better than the 15 we were getting. But, gas prices are rising....we checked out the Chevy Equinox and actually spoke with drivers...all are very happy and very very pleased with gas mileage over 25 HWY and close to 20 in town.

How do you figure you were duped by the dealer? The federal government is the one that estimates fuel economy. I would say you were duped all right. By the Government. Actually I think the admin we have now has been duping us since day one.

Easy with the political jibes, mtnman. People come here to get away from that stuff.
I have a 2007 Santa Fe. My wife have a different driving style than mine, and regularly gets around 17-22 mpg. I drive with a much lighter foot, and let the transmission row through the gears more gradually, and average several miles per gallon. I find the car accelerates just fine ... but you don't want to floor the accelerator, or kick down gears. Aggressive driving in the mountains or in commuter traffic makes the mileage drop off for exactly that reason.
I also use midgrade gasoline, which seems to improve both the Santa Fe's performance and mileage, and keep the tires inflated to the recommended pressure. I also swapped out the OEM tires for something different. All of these things make small improvements.
All time best mileage I've managed in my Santa Fe is 27 mpg - which I managed for a 200 mile trip on the interstate, driving mostly downhill, with a tailwind.

2008 Limited FWD, 40k miles. Right now it has fresh Pennzoil Platinum 5w-20 with a Hyundai filter. I also have a K&N drop in air filter that is cleaned regularly and never over-oiled. My wife drives 70% city and averages 20.5 based on the computer. I've always been too scared to check by calculation. I just put Nitto NT850 Premiums on it in the stock size and they are great tires, mpgs stayed the exact same. I've noticed that it'll drop down to 19-19.5 about every 6 months. I read somewhere to pull the negative battery cable and reset the computer, since it learns your driving habits. I did this a month ago with the oil change and it's back up to 20.5 or so. She works out of her car and carries 200+ lbs of therapy toys all the time with the 3rd row seats down. The therapy stuff comes out for trips.
We've got as high as 27 on the highway, but the mileage falls off considerably above 75mph. 25-27mpg at 70-75mph, 80+ is 22-23.
On the plus side (knock on wood), it's never been back to the dealership for anything. I change my own oil, so no issues so far.

Hi graceh...just wanted to ask you, are you getting your mpg average directly from your car or are you averaging it yourself the old fashioned way with a pen and paper at the gas pump? Just asking because I just bought a 2011 SF & my car computer is telling me that i'm getting 24.3 mpg average, but when I fill up at the pump and do the math myself...i'm really only getting about 16 mpg.

car's mpg calculator is not very dependable.
There is a reset button on the panel. Reset it and then see how it goes.
I also heard that it resets automatically when you refill your tank (i doubt this though).
my 2011 SF AWD SE gives me 18mpg combined and 22mpg highway 70mph.
Yeah, it is not good.
However, it gives 27mpg 55mph.

My husband drives highway 65-70mph. Best he can get is 18.1 to 18.8mpg. Nothing has improved, even after investing a ton of money at multiple dealers. We believe our car is a "lemon" and will never buy another Santa Fe again! We haven't tried to check the old fashioned way.....maybe we should. But, I'm afraid it will bring worse news than what we already have. we're stuck with the car because our trade in would be an enormous loss in $$$. Good Luck!
