I bought 2013 Sorento EX in July 2012 which I have almost 5000 miles it. The best MPG I have been able to get is 15 in the city and 18.5 combined. I have called Kia a number of times, they told that I have to drive the car for about 5000 miles for the break-in. I am almost there and nothing has changed. Now they are telling me that itís my driving and to register for their one mile rebate. My discrepancy is more than 6 mile or over 25%. I have stopped other Sorento owner on the road, they also telling me that they are having the same problem and their MPG average is about 20 to 25% below Kia's published numbers. I will be talking to my attorney to see what is my option. In mean time I am trying to inform potential Sorento buyers the facts and keep them from making mistake of buying Kia Sorento.
