I actually have a brand new 2015 Chrysler 200 limited, about 7,000 mi on it. The engine light came on two months ago, took it to a dealership (not the same place where I got it) turns out the first spark plug needed to be change. Some fluid on it. Two weeks later light came on again and took it back. First spark plug needed to be changed. Then about 100 miles on the car later light came on, I had to use the car for work so I waited until the weekend came to get it fixed. Three days the light was on then it turned off. It seemed fine so I didn't take it. A week later it came on and was going to take it to the actual dealership I got it from. A few days later it turned off by the time I took it there. They couldn't fine anything wrong. That was 5 days ago. Now yesterday it came on. Auto zone says replace first spark plug. What's going on? Does the engine or whole car need to be replaced?

This needs to be physically looked at to give a good determination. It can be an injector leaking down and putting to much fuel in cylinder a bad plug wire or wrong heat range of plug as well as oil getting into cylinder form poor seals. We do not have a lot of info on these as they are new. Also because you didn't give model nor engines size I really can't look up tsb's to see if anything is out there on it.
