#5 of 6 I am having this problem now by jschrots Nov 15, 2007 (11:03 am)
Kialemon......the same thing is happening right now to us. Brought the car in 5 times. Said cylinder misfire and replaced coils 3 and 5. Kia 2006 sedona was still acting up. Now they tell me that they reprogramed the computer and it should all be ok. I am thinking I should just get rid of this car while it is still fixed and be done with kia. I will NEVER purchase another Kia again. I did contact a lawyer for l lemon law, but who knows how long that would take to settle.

Replying to: kialemon (Oct 15, 2007 10:01 am) This may be too little too late, but here we go. I have the Entourage, bought 6/06. The check engine light first came on at about 1,800 miles. Got home, the owners manual sayz it's a loose gas cap. Go out and undo the cap and re tighten, next day light is off. Finally got it to the dealer for an oil change, tech notices light on and resets computer. 1 week later, comes back on, go to bed, next day light off. Finally at the 1st yrs inspection. They had van for a week. Gave me a rental though. The problem was that at about 2,100 RPM's the enguine would read a misfire. They would download the new information but couldn't get the computer to reset. They had to send computer to California so the engineers could work on it. It's been about 12 months and no check engine light coming on.
