Three problems related to overdrive light on have been reported for the 1999 Kia Motor Sephia. The most recently reported issues are listed below.
While driving about any mph when engine check light and overdrive light will come on. This situation had been a problem for consumer sixth times. When lights come on engine will stall. Dealer could not find out what is causing it.
I started taking my car in to the mechanic at the dealership shortly after I purchased the car about the car not shifting correctly and being so sluggish. I'm not sure about the dates I took the car in but it was several times. I was told that nothing was wrong or they couldn't find any problems. It has just gotten so bad that I'm not able to drive the car now. I've had problems with the brakes, the air conditioner, check engine light coming on and staying on and the overdrive light flashing on and off. I'm sure they don't have a record of the many times I've gone by because they would usually just look at it or drive it around the block and say they couldn't find anything. Now that the warranty is out , they have come up with some suggestions at my expense. The car has never performed properly and they just kept putting me off until I finally gave up. I am unable to drive the car now because it will barely get up to 35 miles per hour. I will greatly appreciate anything you may be able to do to assist me. Thanks.
Engine check light comes on, and the overdrive light comes on also. Dealer says it's due to a wire becoming loose and shorting out. Dealer has repaired, but problem still exists.
