One problem related to brake loud noise has been reported for the 1999 Kia Motor Sephia. The most recently reported issues are listed below.
Whenever the brakes (abs) are applied, steering wheel would shake. After going 65mph or better, the entire vehicle would shake/vibrate. The abs brake system was repaired twice.
