My 2010 Mercedes Benz C300 engine light keeps coming on. on 2010 Mercedes-Benz C300

I have had my car in the shop six times and each time it's a different story as to why the engine light keeps coming on. When i complained to MBUSA instead of giving me a definite answer they asked me to take a survey. I don't want to take a survey I want an answer as to why the engine light keeps coming on before my warranty expires. Don't say the gas cap is loosen, been there done that. Last time it came on I had not put fuel in my car.
