My car completely turns off while im driving it, most of the time when I used it the first time of the day and try to used it again it turns of and loose power, I can't turn it on again in that moment I need to wait and then it works again but if happens really frequently and its really dangerous because im on the freeway and cars are behind me and I can cause an accident or anything worse. I went to the dealership so they could inspect my car but they couldn't find anything at that moment. *Tr

The car was running fine until after a few hours of driving it just stopped running. This is the second time this has occurred. The engine rpm dropped to zero and the car coasted. After sitting for less than an hour the car started up again. I took it to the kia dealer and they said, even though the car had less than 60,000 miles, they would have to diagnose the problem and charge us $200 to do so, and the electronic parts were not covered. *Tr

I was commuting. I gave my car regular oil changes and tune ups. Then the engine coils went out. The car would not go over forty. Replaced that. Heard funny noises coming from the engine. The car was at 70k at this point. The manufacturers warranty said to replace the timing belt at 110k. So I decided to hold off as that probably wasn't the problem and a manufacturer wouldn't lie to me as they are regulated by the government. Then I am driving and the car dies in the middle of a busy intersection. I get the car...

towed. The timing belt is changed and there are half the teeth left on the timing belt. How is the car still running you may ask? It is a magical car and is like the little train that could. Then I am driving on a busy scary mountainous highway and the car dies again at a blind corner. No check engine light but there are plenty of cars that want to hit me. The car turns back on. The fear for my life and those around me has subsided for a moment. The car is able to turn back on... Somehow. The check engine light stays on. The crank sensor is the problem. The crank sensor was then fixed. This car is a hazard to have on the road. The air bag light has also been on for a year and won't go off. I have had to replace engine coils, door locks, trunk alignments and probably some other things that made me fear for my life. The speedometer also broke and said I was going 0 mph when it was really 80 mph. As of right now the car is running okay. I expect by next october that something will go wrong as that is the month that everything does with this car. *Tr

Tl*the contact owns a 2004 kia optima. In june of 2004, the exterior lighting failed while driving at an unknown speed. In addition, the driver's side door would not lock and the check engine light consistently illuminated. The contact took the vehicle to the dealer and the exterior lighting was repaired; however, the door was not because it was not under warranty. After the repair was made, the exterior lighting continued to fail as well as the other issues. She took the vehicle back to the dealer...

Ry time it rains and our county dirt road gets wet and muddy. Mud splashes up into the engine compartment and into the egr valve and causes it to malfuction due to the way it was desined. I took the car to the dealers shop and was told it was a maintence problem and that the dealer would fix it only once and after that I will have to pay for any repair if it fails again. As of this date ( 03/24/05) this car had 23760 miles of a 100,000 mile warranty on it. *Ak
