Door Latch problems of the 1997 Kia Motor Sportage

Kia Sportage 4 door. Rear driver side passenger door would not open from outside. Door opened from inside. Door was then shut and did not latch, upon second closing door latched. Drove around two miles and went around curve at about 10 mph door latch released and door flew open. 16 month old child was in car seat beside the door. Door had to be strapped to other door to keep shut. Car taken to dealer who said latch was rusted out. Ordered replacement latch, other back door has shown same symptoms of not closing and then closing and latching, also not opening from outside. This would have been a serious incident if child had not been in safety seat, probably resulting in a death.

Driver's side door opens and closes intermittently. Also, horn doesn't work, and there is a rattling noise underneath the hood. Door will be repaired, dealer could not find problem with horn or under the hood.

When driving doors will unlock. Also, when consumer parks and gets out the doors won't lock. Vehicle has been in repair shop four times for repair service. Consumer just got the vehicle out today for repair service.

Locks are not operable. Driver's side door lock is suppose to lock all of the doors on vehicle.
