NHTSA lists 5 safety recalls and 428 owner complaints for the 1999 Kia Sephia. Most complaints involve service brakes, hydraulic (160) and engine and engine cooling (82). The EPA rates it 23–24 mpg combined.
ON CERTAIN PASSENGER AND SPORT UTILITY VEHICLES, THE FRONT SAFETY BELT BUCKLES MAY EMIT A "CLICK" SOUND DURING THE BUCKLING PROCESS THAT IS SIMILAR TO THE SOUND EMITTED WHEN A BUCKLE IS BEING LATCHED, WHEN IT IS NOT.
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.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE ELECTRICAL CIRCUIT FOR THE FUEL PUMP IS GROUNDED AT JUNCTION CONNECTOR G300. IF THE PIN TENSION IS POOR, OR THE BOLT SECURING THE CONNECTOR TO THE VEHICLE FLOOR IS NOT TIGHTENED SUFFICIENTLY, A POOR CONNECTION IS MADE. AS THE FUEL PUMP OPERATES, THE POOR CONNECTION CAN CREATE HEAT WHICH IN TURN INCREASES RESISTANCE. EVENTUALLY THE FUEL PUMP WILL NOT RECEIVE ENOUGH CURRENT TO OPERATE.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
