2002 Kia Sedona electrical system problems

2002 sedona was repaired 2 times with less then 200 miles on it for battery draining- claim was it was the radio didn't shut off with the car. Then last month with 59.000 miles on it I complained of the car hesitating and lights flickering, airbag light came on for no reason, claim to repair was tune-up- 1700.00 and two months later my battery went on fire with 5 people in it, 3 children and one is carried out handicapped.

When the electric lock is used on the kia sedona it disables the following: electric windows, dash lights (all) interior dome lights and tail lights license plate light and all parking lights are lost. After setting overnight the systems come back on line so far. However if someone hits the locks and it is at night, all the light that another driver would see from the rear are out. The driver can not see any instruments at all. And any windows that were open will not change position.
