I have been taking my car to kia of orange park in jacksonville, florida for the past several months because of issues with stalling and hestitation at start and the car has stopped on my while in gear with my foot on the brake (three or four times). Each and every time I take it to the dealership they seem to say the vehicle will not duplicate the concerns I am having. I have been afraid to go a long distance with the car because of these issues. I recently switched to southside kia in jacksonville, florida and they convinced me the car was fixed after replacing sparks plus, fuel pump, gas tank valve, and on one ocassion they found the tps sensor loose from the previous kia dealership doing a throttle body service. I am very dissatisfied with kia right about now and have not been able to get any help.

The fuel system is giving me problem after problem after problems I have changed the fuel pump 3 times in 12 months. And the head lights also keep going out. I've changed the left side head light twice and the right side once in 4-1/2 years.

Purchased 2004 kia optima ex new. Have had fuse block replaced w/in 15000 miles. Now, the fuel pump has failed. The car ran fine and was parked. Next day car would not start. No fuses blown. The terminal connector from the fuel pump to the gas tank penetration has burned out causing an intermittent open in circuit. Fuel pump burned up in tank. Wires and connectors visibly charred. Connection that failed is inside of the gas tank. Very similar to ntsb case #10161074. Have 120,000 miles on the car. Others with less mileage are in for trouble due to poor engineering design. Defective parts available for photograph or inspection.

Dt*: the contact stated while traveling 25 MPH, the vehicle stalled without warning. The gas cap was removed and replaced to remove pressure in the fuel tank. When the vehicle was restarted, it was sluggish, and had very little power, and a clunking noise was heard. So, the vehicle was towed to the dealership. The dealers mechanic ran a computer diagnostic test, which revealed several misfire codes. Upon removing the fuel pump, melted wiring was discovered running from the fuel pump to the gas tank. The manufacturer was alerted.
