One problem related to power train has been reported for the 1997 Kia Motor Sephia. The most recently reported issues are listed below.
When I bought the car the brakes felt bad because I had to push the brake all the way to the floor. After having it for 2 weeks other thing started to go wrong. I had to buy a cap and rotor and get spark plug and wires. Now the transmission is messing up. They are not willing to put me in something better. They want me to pay on a junk car that I will always have to be fixing day after day.
