Three problems related to transmission gear slipping have been reported for the 1998 Kia Motor Sephia. The most recently reported issues are listed below.
The ignition system is hard starting at times, even right after I got a tune up from the dealer. Glovebox has been replaced once before because the closing mechanism jams and will not open. Transmission has slipped, shifts roughly since new. The brakes grind constantly, dealer has replaced rotors, then replaced brake pads after that, now grinding again.
Transmission slipped and vehicle stalled/ malfunctioned. Contacted dealer, and dealer replaced transmission, but problem still occurs.
When the transmission was in reverse, it would pop out of gear into neutral. Then vehicle would stop. Also, abs brakes were replaced twice due to excessive wear to drums. Headlights would have condensation, and dashboard was replaced due to cracks. Vehicle now on third transmission and it still slips out of reverse when backing up.
