Kia unwilling to fix problem with car

About two and half years ago, I bought myself a KIA Cerato Koup. For the most part, I'm very happy with the car, however, there is one very irritating problem that I just can't get any satisfaction for. Over the last 2 years I have replaced head lamps in the car 4 times. My previous car (an old Ford Fiesta) I think I changed head lamps once in about seven years.<br> <br> When I bring the problem up with my local KIA branch, I get told that it's a problem with that model. Well, I don't think thats a good enough answer. When I bought the car (new) I didn't expect there to be any problems. Also, considering the fact that KIA have effectively admitted that there was a problem with the car when I bought it, surely this should be a Warranty claim, and not come off my service plan every time I change the lamps.<br> <br> further still, I find it very disturbing that the common response is that \the people in Korea need to fix the problem".
