I have an 06 Optima (06. 5/ ms) 2. 4 engine but the problem im having juging from kia internet forums is spread acros meney years and models it is an intermitant engine stall it can happen at any time ive had it happen at 65mph on interstate this is followed by a series of start stall then it will run fine for a while ive had a complete wire harness check reaced several sensors and other parts nothing has cured the problem it should be recalled and repaired by kia before some one gets hurt not after. This is a totally random happening.
