Bought the car used and had it in within first two weeks with 6k miles on it for warped brakes. They repaired. Now it has 68k miles on it and had all maintenance. 2nd owner and now we are told the antifreeze is going thru the turbo and into head gasket and Kia will not do anything. We were not aware the 10 yr 100,000 miles was not transferable. 6k miles out of warranty and they want us to buy a motor. This car has always been maintained and should not need a motor with only 68k miles. The optima-??s had the same issue as we also have an optima which was covered due to recall. This should be looked at. The dealership charged us 200 for diagnostics and said too bad you pay for it.

One day I was driving my car when suddenly I heard a loud explosion sound from the back. I continued to drive the car until I could pull over to inspect the car. In the midst of pulling the car over I began smelling a strong odor of gas in the cabin of the car. Prior to stopping the car started skipping and missing badly. I pulled over checked the car and discovered something malfunctioned and caused the rear seat to pop up and be bent from the frame. I proceeded to look under the seat and saw where what appeared to be the fuel pump almost popped out, the bracket above the fuel pump was broken and popped up from the explosion, the seat would not go back in place. I looked at the gas hand I went from 3/4 tank of gas to E in less than a few miles. The exhaust also sounds like something blew or came apart the car runs very loud and you can hear the car sounding like the exhaust have a hole. After the sequence of events the engine light never came on. This is huge life safety problem that should have never happened.

Vehicle engine shut off while driving down the highway. Traveling on 74 and while still in drive the engine abruptly shut off. Vehicle was started again and then it again shut off a couple miles down the road. When the vehicle was started a 3rd time it immediately went into limp mode. I was stuck on the side of the highway with vehicles going 70MPH around me. On my way to the dealership the car shut off multiple times potentially killing me multiple times. After 60 days at the dealership they said they fixed the problem. I drove the car 4 miles and it shut off on me on the highway again. I had a car almost crash into me along with trying to start the car and get off to a safe location. I still do not know what is going wrong with the vehicle but this could of killed me and others..... this needs to be addressed along with the fact they gave me the vehicle back just for it to do it again.

While driving the vehicle and after it is parked and engine is turned off the cooling system ( coolant reservoir on upper right side of engine are) allows antifreeze vapors and high pressure to escape into engine area. When parking in a garage there is a very strong smell of coolant. Dealer has verified that the radiator cap appears to act as a vent allowing vapors to escape the system.
