Problem: Vehicle description: passenger vehicles. Manufacturing changes were made to the orvr spring force and float wire length reducing the valve angle. Certain valves caused fuel shut off before the tank reached 95% of nominal capacity.

Risk: This would cause customers to add more fuel to the tank causing fuel spillback or spitback from the fuel filler neck.

Fix: Dealers will replace the orvr valve. Owner notification began november 13, 2000. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact kia at 1-800-333-4542.
