I brought a new kia sephia in 1998, and had nothing but trouble with it! Transmission was replaced 2 times by the mechanic for kia motors, and needed to be replaced again on 7/2007. Also , the brakes have been replaced 4 times and need to be replaced again. Now the headlights keep turning off while driving at night, but no mechanic can locate the electrical short problem.
