I have a 2010 Chrysler 300 S, 5.7L V8. Today the check engine light came on and the car will not switch into the Eco mode when driving at normal highway speed. Any suggestions?

When the Check Engine light comes on the Engine Computer detected a problem and set a diagnostic fault code. Have that code read at an auto parts store. Many will do that for you for free. It's important to understand that codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis.
