My 2003 Sedona LX with 35000 miles has a problem with the front brake rotors heating up to the point that water sizzles when it comes in contact.  2 different tire shops broke off one lug bolts each on the front wheels.  (I'm assuming because the metal heated up so much)  I can't find replacement lug bolts anywhere. (Even at the dealership)  I have yet to find time to take the van in to the Kia service center.  I will update later on my progress
