Gas mileage is a big concern at this point. This car is primarly my shuttle to and from work, a 26 mile round trip with about 15 miles 2-lane highway and 10 miles interstate. I only have a quarter mile or so from my house to the highway. I'm only getting about 24-25 mpg according to the computer. I was expecting more since its over 90% highway miles.

Unfortunately, the computer seems on the high side and about 2-3 mpg better than my manual calculations. I've been very careful filling up the same way each time and keeping accurate manual records. Anyone else notice the computer mpgs may be off a bit?

I'm also getting about 2 MPG off from the computer every time I calculated. Number of people also mentioned same thing as you mention on MPG. I'm getting AVG 25 MPG actual mileage on my 2013 EX GDI Sorento (30% local / 70% freeway).

My case has now been escalated to the regional Kia rep but I cannot get in touch with her despite having left multiple messages.

Have anyone replaced the alternator and idler pulley to resolve GDI rough idle issue? I also contacted the KIA, but they didn't mention anything about replacement of the alternator and idler pulley.

The alternator and pulley were replaced and the idle is perfect now. No more flickering lights either.

I took mine in to complain about this same issue. They told me it was normal. I told them that this is only normal if you bought a Harley. Then I saw your comments about the flickering and that it was fixed last week. I sent this message thread to them and they called Kia. There is now a service bulletin for this issue. The parts were ordered yesterday and should be in today.

Just picked it up and indeed, it was fixed!

Yes, it was.

I was told that the floor mats on KIA Sorento are truly carpeting, but that the actual full carpeting was FELT. After he said this, I could tell the difference in the feel and texture. My guess is that without a mat, the full 'carpet' will wear fast. One of the reasons why KIA costs less than BMW!!!
