Since May of 2002, this car has been in the shop 9 times and of this date it is still there. First they said it was fuses. Actually it has never run or started right. It had to be towed at least 4 times. The last time that it went in was 8/5/03, they fixed the water pump, belts, crank pulley. This was all under warranty. When I picked up my car it made a terrible sound. They said it was the new belts. So I drove it home and 2 days later it?s back in there. The next day sabrina called and said that it was the air conditioner compressor. It was going to cost me over 600.00 to fix it. I have a limited income of 535.00 a month, am disabled and if the car broke down I don't know what I would do.. The car is still at Kia dealer ship, that's as of today.

At this present time my car is sittting at stonemountain Kia whereas it is in need a third battery all within less than a years time.

The driveshaft is always sticking in the gears. The air bag light continually blink and stay on for periods at a time. The exhaust still making loud noise that I have complained about since I brought the car. …

Since purchase have returned car under warranty at least 10 times, always for the same problem having to do with the catalytic converter, emissions system, and brakes. About once a month, check engine light flashes, car lurches and is shakey, often with a funny noise and bad smell. Dealership has "fixed" same problem each time, to no avail. Danger factor has increased as I now live in snowy climate. Car has no power, then lurches forward at high speed, stops in traffic, stalls or won't start at all. Tachometer goes up to 4 or 5 before leaving first gear (car is automatic). Dealer sold this car to me as a demo, but contract says used. Help -- this is a terrible, dangerous car and has been in the shop for at least 90 out of the last 300 days.

Tail light had to be replaced because of leaking, this is 4th time for brakes squeaking and pulsating, cow panel baffle needed replaced because of water pouring in behind glove box.people I don't know pull me over and complain about their Kia sephias and similar problems with them. Also the engine sometimes won't start the first time. It takes two or three times once in a while. It also sounds like the engine will jump right out of the car because it jerks so hard when starting. The gas tank has yet to let me fill it all the way. It gets almost full, then spits the gas out and won't let you "squeeze " it full. It's like there is no venting going on. I have heard similiar reports from other owners.

Courtesy imports-henderson nv. I won't recommend this car to anyone. Car's engine lights came on, we took it to the dealer , but problem could not be duplicated the first time, again engine lights came on, car drives poorly- shifts terribly, jerks and engine revs in idle. , we took it back, tune-up suggested, tune-up done. Still engine lights come on, we bring it back, pick it up when ready, return it for same problem, now on 6th return for repair since 7/17/00. I think it's a real lemon. I just want my car back working properly! It's a terrible car. If you want me to fax you the work orders/service history sheets I have I loved too.
