I had a fog light that did the same thing, the dealer just replaced the whole unit, when they eventually got the right part. I kept telling them that the 2000 on fog light wouldn't fit but they ordered it anyway.
I know some cars with new xenon(or something expensive) lamps like Audi's etc mist up because they aren't actually a sealed unit but I don't think the Coupe's use them, but maybe the brand new ones do, sure somebody on here will know and for sure the dealer will.
I had a Nissan Micra courtesy car last time which was an enormous improvement over the Kia Rio I had previous. Just got a nail gun and attached throttle pedal to the floor and steered around everything
As for the Rio it really wasn't a courtesy at all and next time I'll walk, in a blizzard if needs be. It had a 1.5 litre engine - 1.5 litres of what exactly I'm not sure, it made a lot of noise when you put the throttle pedal down just didn't seem to go forward any faster ! And the less said about it's idea of cornering the better
