I'm not sure if it's related,but some 2001 Elantras (mine included)had problems with the headlight bulbs burning out.I've had to replace mine 3 times already although the dealer covered the bulb and labor. There are certain bulbs that are covered under your warranty.You could check with your dealer and see if the foglights are one of them.Hopefully they are upfront with their answer.My dealer was not and I paid for the first bulb before I found out about this.
