I've had my '12 Sorento for 6 months now.
My daily driving is roughly 50 miles to and from work.
A stop at the babysitter, mostly highway. I get 22-24 MPG depending on the insanity of traffic.
We recently took a family vacation from PA to RI and driving conservatively we got a hair over 30 MPG.
Driving home we drove more aggressively and still got a little over 28 MPG.
The only negative I have to give is each side does have a blind spot and you can easily side swipe someone as my husband and I both have nearly done.
It would be nice to have a V6 but the only time I really wished for it was on our vacation getting through some tight areas.
