This has been a nightmare. I washed my car, and started to head home when I noticed a little knocking sound under the hood. I thought, well it has idled a minute so maybe the lack of Rpm's is the cause. I pressed the gas, and it stopped. I went on my way but after about 20 miles, it began making a completely different sound. I stopped it immediately, popped the hood, checked the oil, coolant, radiator, and S-belt but noticed nothing out of the ordinary. I tried to start it, nothing. Again, still nothing. Third time, started but a definite jarring was going on under there this time. No more for me.... called roadside assistance then today the shop tells me "I need a completely new engine." Now, its a wait to see if Kia plans to cover this catastrophe. If not, I am still on the hook for more than $6k bank note and the engine. Geez. Anyone else?
