I'm a new 2011 Sonata SE owner and just discovered something that I'm not sure if it's a problem or not. I looked through the owner's manual and can't find an answer. The engine start/stop button has a small (? led) light on it. Mine never lights up. I would think it should light up when the engine is running and turn off when it's not. Is this behavior normal or should I take it in for repair? Thanks in advance for any responses.
