I bought my first new vehicle.
2011 Hyundai Santa FE AWD SE v6. Done 1500 miles so far.
mpg are heartbreaking.
Pure highway 230 miles = 13gallons = 17.6mpg.
Speed 70mph. Temperature 32F.
Tire pressure OK
Load = 1 passenger
AWD lock = OFF
A/C = OFF and yes, i drive very smoothly.
I did several long distance highway trips and i got just about same mpg.
This is heartbreaking and very disappointing.
Any inputs would be greatly appreciated.

I purchased a 2010 Santa Fe 6 months ago. The gas mileage is improving as I rack more miles on the car. I've been told it should get a lot better around 7,000 to 8,000. I have about 4,000 right now.
Please keep us up-to-date.
Thanks Big Bruno

Thanks. How much do you highway mpg do you get for your vehicle?
Did you do anything special (ex: synthetic oil change, engine flush etc) do get more mpg?

You're welcome. When I purchased the car, I was getting 18 MPH (mostly suburb driving). At about 4,500 miles, I'm getting around 20 MPG. My friend also has same car (4 cylinder front wheel drive) and is getting 24 MPG at 7,000 miles. Hope this helps.

thanks. 18 or 20mpg for city is quite good and close to EPA.
However, i am not sure how much will my Santa Fe progress from 18 mpg HIGHWAY.
At times, i wonder if my Santa Fe is internally always locked in AWD OR
is it incorrectly configured to have very rich fuel : air ratio?
Do we know how is the fuel : air ratio controlled? Is that something we can check?
I will continue posting here.
Thanks again for your inputs and wish you 'Happy Holidays'.

FYI, I was told the same thing by a dealer in San Diego but I now have a little over 25K miles and never saw any big improvement (I have a 2007 FWD Limited 3.3). I got so fed up that I opened a case w/ Hyundai and they arranged for the District Manager to look at the car. He measured the mileage on the highway (he actually did a pretty "controlled" experiment, noting the route he took, speed (70 MPH) having A/C on, etc.) and got 21.9 MPG. The problem with that is the it's the suburb/city mileage that is bad and the one that really reflects how we use the car (we get around 18, being light on the gas and hardly no A/C).
After that, I pretty much gave up on getting better mileage. My "theory" is that other drivers get better mileage due to variances on car build (besides differences in driving style, terrain, etc.). Any suggestions would be appreciated...

In my case, i topped the tank and started for NH from NJ.
I again had to top up the tank in 230 miles. had to fill in 13 gallons.
So, this was pure 100% highway miles 70mph.
No slow traffic.
To me this is very discouraging.
Can you please tell me the path to get Hyundai's attention?
I would wait for another 2-3k miles before approaching them.

When I bought my Santa Fe, I was driving it in the local area and on the highways. I was getting 20 to 23 mpg. I then retired and drive mainly in my local area which involves more stoppng and starting. My mileage is now down to 18 to 19 mpg. Also, I noticed a big difference when the cold weather came. It took a lot longer for the "ECO" light to come on. I am assuming that is also causing less mpg. I am still satisfied with the car. It is a 4 cly model.

Something is definitely wrong with our 2009 Santa Fe. We cannot get more than15 mpg on the highway. My husband has been back and forth with multiple dealers and nothing has improved in the past year. We are now looking to buy an Equinox! Any suggestions???? please???

Is it a 6 cylinder or 4? Is the car under any warranty? did you buy it new or used? What are the dealers saying/doing? thanks Bruce
