Tap a recall to see the problem, the risk and the fix.
Child seat
Problem: Certain passenger vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 225, 'child restraint anchorage systems.' certain child restraint anchors will not fully latch onto the lower latch anchors located between the rear seat back and rear seat cushion because of interference between the child seat anchors and a metal wire located in the frame of the rear seat back. Until the recall repair is completed, follow the instructions provided by your child seats manufacturer on how to properly install the child seat with your vehicle's rear safety belts rather than using the latch system.
Risk: In the event of a vehicle crash, if the child seat is not properly installed, personal injury or death could occur.
Fix: Dealers will replace the lower anchors free of charge. The recall began on january 30, 2006. Owners may contact kia at 1-800-333-4542.

Problem: On certain passenger vehicles, the fuel intake nipple of the fuel distributor is subject to fracture or cracking during removal of the quick connect coupling securing the main fuel tube assembly to the fuel intake nipple, or when force is accidentally applied to the intake nipple during the vehicle assembly process or during engine compartment repairs.
Risk: Fuel leakage in the presence of an ignition source may result in a fire.
