Your engine light is designed to come on when it detects a

problem. Usually it comes on in the very early stages of a problem

so that you can reslove the issue before it becomes more costly.

The best thing to do is take it to a certified mancanic such as a

local dealership and ask them for a check engine diagnostic. They

will check the engine code using a diagnostic tool which is plugged

into your OBD 2 system that will tell them exactly why the light is

on. Since you have a fairly new car the light could tell them any

thing from a engine misfire to a malfunction in your transmission.

At any rate don't be to alarmed, just have it checked out as soon

as you can.
