My car makes the same rattle noise when I cold start the engine, sometimes even when it is warm. Meanwhile there are no rules. My dealer said that it is totaly normal for the 1.0 turbo engine to sound like that , but I am not so sure if this is the case.
I've red about this in some German forums as well. Same answer from the dealers there too: It is a normal 1.0 three cylinder engine start sound.
Well, I still don't agree, like the most of you.
I will take the car to my dealer next week again and they will check for more details then. At this moment my milage is about 1.500. Not much.
I am not that worried as KIA/Hyundai cover this with a warranty, but it still would be great if they would fix problems if there realy are some.
Heres a video with this terror sound on the startup (second 4-5):
