Five problems related to overdrive light on have been reported for the 1998 Kia Motor Sephia. The most recently reported issues are listed below.
I have had my car for about 7 months, and I have found out that it had 5 recalls and the problems I have had consists of check engine light coming on and o/d light flashing. Also, car acts as if it does not want to go into gear. When it is put into reverse it also seems as if hesitate to crank up as well.
Engine check light and overdrive light would flash, second time vehicle just quit, this was second transmission vehicle has had.
Check engine light on & o/d light flashes after almost every 300 miles since recall campaign to replace orvr valves was serviced by dealer. O/d light flashes would then follow engine stalling (after driven 150 miles) and would only crank engine but wont start. Also after orvr was replaced, every full tank of fuel ( 12. 7 gals. ) would cause hesitation but would go away after driven for 8 miles . Engine stalling luckily occurred only on street roads but could pose serious risk if it would happen on freeways.
Overdrive light keeps coming on, and the front brake pads had to be replaced.
Break pads and rotors need to be replaced approximately every 3000 miles when car is taken in for oil change. I could not fill the gas tank completely when I first purchased the car because the automatic shut off. Gas tank and float valve were replaced after waiting a month for the parts. Check engine light would stay on and o/d off light would flash, called dealer and had to wait a week for appointment. Dealer stated new coupling was needed. Waited month for part. When I went to pick up car, dealer stated it need a new transmission instead. I waited two weeks for parts. Now car is at dealership again because it will not start. Lights, horn, radio, etc. Still operate.
