First thing is the thermostat.
Second thing is the radiator that went bad because of the thermostat.
Third is the starter which went out after the strut did.
Now its the Exhaust and oil leak.
This car is a "fair" car for six months then it's a lemon.
I think the issues you've run into aren't unreasonable for a 9 year old car with 160k miles.
I agree with the comment above, and with all the other reviews that I have read you are luck that you got even 100K on those kias because those were one of the first ones and the worst ones. the new one are almost up to the quilty of the japanese cars.
