Mines the same (been like it from new), complained to the supplying dealer but he has told me it is normal when cold, but I'm not convinced as I've listened to others and they aren't as noisey from the outside when being driven. Until the dealer agrees to invetigate there isn't much can be done other than report the dissatisfaction to KIA customer service, at least that way they have it on their records that you have reported a problem if the engine fails.
I have been told that the valve gear is hydraulic (self adjusting), so unless there is a restricted/blocked oil way there shouldn't be any problems.
It might be a silly point, but make sure the oil is kept up to the mark and, while Kia may not state it as a requirement, an oil change every 6K miles may not go amiss, depending on your driving style etc.
My new CRDi also sounds like a trcator when cold but it evens out quickly. I don't think there's any fault there. I've been told that the solution (used by other manufacturers) is to increase the fuel ratio when cold, so wasting fuel but decreasing noise. I'll stick with the noise !!

Have just completed 12500 miles on my XE 5 speed auto in 11 months from new, has a dragon chip on it recommended by Ian Malthouse, it's now getting to be quite a quiet engine, did rattle a bit at first when new and seems to rattle more without the chip but generally purrs.
I'm just awaiting for the delivery of an XS 5 speed auto so I will do as before which was an oil change at 5000 and fit the chip again. Fingers crossed that I will be as happy with the new one as the one I am trading in, which I think I'm mad to do but want climate control.
Generally I think you have to give the engine a good run in, wait till you have at least 10000 on the clock, then you should start to be satisfied with the engine as it wears in.
i have the 2005 sorento xse-GRRREAT car.
mine is noisey when cold also. ok when warm. Mine is still too new to be looking at an oil change yet, however:
i have owned several diesels before and the best stuff i ever found, for an engine, and it quietens them down a lot is 'slick 50' additive. expensive but fantastic-noticably better mpg too.
to top it off (as the 'slick 50' additive is only a small amount of oil), using mobil 1 oil as well is the absolute best combination i have found by far. again a tad dear though.
hope this helps. and i will be amazed if you don't notice the difference in noise AND mpg.
