NHTSA lists 6 recall campaigns for the 1998 Kia Sephia. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
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 PO
Risk: THIS CONDITION COULD CAUSE THE ENGINE TO STALL, INCREASING THE RISK OF A CRASH.
Fix: THIS CORRECTIVE ACTION IS BEING PERFORMED IN CONJUNCTION WITH RECALL NO. 99V317.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. ELECTRICAL CURRENT TO THE FUEL PUMP PASSES THROUGH THE C304 AND C305 CONNECTORS. IF EXPOSED TO MOISTURE, THESE CONNECTORS COULD CORRODE. OVER TIME, THE FUEL PUMP WILL NOT RECEIVE ENOUGH CURRENT TO OPERATE.
Risk: THIS CONDITION COULD CAUSE THE ENGINE TO STALL, INCREASING THE RISK OF A CRASH.
Fix: DEALERS WILL REPLACE THE EXISTING CONNECTORS AND REPOSITION THOSE CONNECTORS TO AN AREA WHERE THE PLACEMENT IS DESIGNED TO PREVENT CONTACT WITH MOISTURE.
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 REM
ON CERTAIN PASSENGER VEHICLES, THE SAFETY BELT BUCKLE MAY "FALSE LATCH" AND EXPOSE THE DRIVER TO UNRESTRAINED MOVEMENT DURING A CRASH.

What stands behind each score for this car:
Owners have filed 713 complaints with NHTSA for this model-year, and service brakes is the most reported area with 189 of them (27%). There are 6 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 81/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 79/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1998 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 71/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
