Power seat motors in your 2023 Kia Carnival that seized after flood exposure have likely suffered internal damage from water infiltration. Seat motors operate near floor level, making them among the first components affected by flooding.
How Flood Water Damages Seat Motors
Power seat motors are located under the seat near the floor - the first area to flood. Water enters the motor housing, causing internal shorts and corrosion. The motor windings can short against each other. Bearings seize from rust forming on lubricated surfaces. Even if the motor still turns, damaged components may fail soon.
Carnival Seat Complexity
The Carnival's available features include power recline, lumbar, fold-flat, and memory seats with multiple motors per seat. Water can affect some motors while leaving others functional. The seat control module processes switch inputs and controls all motors - water damage here affects all functions.
Assessment Process
Try each seat function to determine which motors are affected. Listen for motor sounds - clicking or grinding indicates internal damage. Complete silence means the motor or its circuit has failed. Check the seat connector under the seat for water intrusion and corrosion.
Repair Options
Individual motors can sometimes be replaced separately if the seat frame and tracks are undamaged. Complete seat module replacement may be needed for extensive damage. Flood-damaged seats may need complete replacement including frames, tracks, and upholstery. This is a significant insurance claim item.
