I know that this is a tad bit late but here are my thoughts after owning the Sante Fe Sport 2.0 for a little over a month.
The suv has a great fit and finish. Though I am not getting the advertised gas mileage, I still get between 27-29 on the highway and average about 23-24 mpg for mixed driving. This is pretty good considering the size of the suv and the power it produces. I do wish the turbo was a bit smoother. After owning the Turbo and have driven the standard engine, I think that the standard engine has plenty of power and delivers power more seamlessly than the turbo.
One thing I am experiencing problems with is the fuel gauge or fuel sending unit. I took my vehicle into the shop due to erroneous fuel gauge readings. After 30-40 miles, the tank shows 3/4 full and when empty, I can only add 12 -13 gallons, however this is a 17 gallon tank. something is definitely wrong.
The other issue I have is with the electronic steering which provides a vague feeling or lack of road feel. I think that this idea is cool, used on some BMW 5 series at one time, but it makes the steering feel loose or odd. I would say that you drive the SUV in various modes (Comfort, Sport, Normal) to see if you like this electronic compensation. I wish they would reduce the effect as I am not a big fan of this electronic steering.
