The car is difficult to start and the check engine light remains illuminated.

What is your question?

The car sounds like it's about to turn over but doesn't. My son drives the car and is the only one who has the "magic touch" to start it. The dealership from which it was purchased has looked at it and "supposedly" fixed it, but the repair didn't last. Is it possible that it needs a new starter? I've read the check engine light is a common problem. What to do?
