Consumer Description

My Kia Optima randomly stops working while driving. I get a notice that says, "HEV: Check Hybrid System. Stop Vehicle and Turn Off Engine." Also the gas pedal stops working, leaving me to try to coast to safety. The car essentially stops working in the middle of driving, without warning. Once this happened and blew out the spark plug, requiring a new one. Then, a day or two later, the car returns to normal. The Kia dealership could not reproduce the problem, nor could my service center. They say it's fine. I took my car in for previous recalls, and it is currently "up to date." This appears to be the same electrical issue as a recent recall for electrical failure, but the dealership told me the spark plug was fine and that I should change the battery. I did and this still happened. I do not feel safe driving this car, and Kia won't help me find the problem.
