shapiro - I'm in the same boat. Please let me know how it goes. I'm 100% certain we did not get one when leasing. I've called Kia directly and they could not give me a part number. They couldn't even find a picture of what one is supposed to look like. I'm stressing about the $500 as well.
Worse come to worse, I'm going to return it and pay all the charges that are legit and short pay $500 if they try this. It'll go to collections and I'll just ignore the calls. My credit score will come back up in no time, but really don't want to take that route.
