The TPMS light came on. Within three miles I pulled into a service station to check my tire pressure and discovered that my driver's side rear wheel tire stem was cracked and leaking air. This is the second time a stem on this car has cracked. In both cases I had not hit any potholes or did anything to cause this damage. Kia forums report that this seems to be a problem with Kia Fortes and souls.
