There are many causes and reasons why that fluorescent demon came on. It doesn't mean major disaster. The light could indicate a more serious issue but it could be a simple as a loose gas cap. Our service department will perform diagnostic for you. There are literally hundreds of codes that can cause the light to come on. The codes themselves don't determine exactly what parts are bad but will point the technician in the direction for further diagnostics.
Check engine lights are NOT typically covered under your warranty with Auto City and loaner cars will not be provided.
Once the codes have been obtained our service personnel will be happy to schedule the work to be done or you may take the vehicle to the repair facility of your choice.
