Filled tank & had overflowing spillage down side of car (indicated very full tank) finished cleaning up excess fuel & turn car on but the fuel gauge would only read 2/3 full, then needle rose to 3/4- I just got the car on monday 11/7/16 & this has happened twice now, once when leaving la after buying/transferring title & again today. Decided to google the 'symptom' & I'm shocked that a 17-year-old car from 1999 had recall records but was never fixed!!! Previous owner(s) was older couple that had bought it from a dealership & owned it since 2004. The 17-year-old '99 sephia has only 75k miles on odometer as of november 2016 however was never repaired under recall order.

I've had many problems with the catalytic converters disintegrating from within. I've had them replaced many times at least 3 or 4 times in the last 2 yrs the most recent was this summer about 2 months ago. I am having this problem again it begins to act like it's going to stall, then starts vigourously shaking, and it also loses acceleration speed. I'll be driving and all of a sudden it starts acting up and losing speed and it wont go any higher than 20 MPH or so. This is a continuous problem and one that I consider very dangerous because I could be driving on a busy street or a hwy and I lose acceleration speed and it shakes. This poses a problem to my own safety and that of others driving while these effects occur. I'm scared it will blow up, burn up, or fall apart with all the shaking or even stall and cause a major accident. Please help!!! I've taken it numerous times to the dealership to get this fixed and I've only gotten a temporary fix as you can see. If its not the catalytic converter, its the fuel injectors, or the fuel gauge, it's always one thing or anther. This car is a lemon!!!

It does not seem like I'm able to get the gas tank completely full. As soon as the pump clicks off you cannot get another drop in and then when I leave the station and go only a few miles the gas gauge is already moved off full. Referenced in rq03-006

When trying to stop the vehicle there is a horrible vibration. It is very hard to control and stop the vehicle while braking. Our gas tank will not take in gas. The tank could be completely empty and it will take a dollar's worth of gas, then gas will start spewing out all over. Our car dealer said he doesn't know what it could be and hasn't heard anything from kia about this being a problem. (it isn't the gas gauge.) the air bag light came on and stayed. We got this fixed and haven't had problems with this again. Also, we have a manuel transmission. We have had trouble with it kicking out of gear. We could be going down a highway and it will kick out of fifth gear. It does its own thing. We have had this vehicle since august and it has been nothing but problems. My wife and I no longer trust this car and this is the only vehicle we have to rely on. We also have gotten 2 recall notices from kia. One for the wipers, they can fly off at any given time and for the fuel pump being improperly installed. We contacted our dealer and they said they are waiting for kia to send them more parts, until then we must wait to bring our car in to be checked out. We have been waiting.

Fuel system, gasoline: delivery: fuel pumpReported November 9, 1999 · 102,944 vehicles affected
What is wrong
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.
Risk
This condition could cause the engine to stall, increasing the risk of a crash.
Remedy
This corrective action is being performed in conjunction with recall no. 99v317.

Risk
This condition could cause the engine to stall, increasing the risk of a crash.
Remedy
Dealers will replace the existing connectors and reposition those connectors to an area where the placement is designed to prevent contact with moisture.
