I own a 2001 KIA SEPHIA/LS. Often when I drive up a steady, steep grade such as Gorham Hill or through the notches(route 16) from Berlin to North Conway, NH the car emits a "burning hair" smell. The temperature guage reads normal, I've tried overdrive and no overdrive...there is no difference. Once I am beyond the hill, the smell goes away. Call me a paranoid woman, but should I be concerned?
