normal if it sounds like marbles in a can rattling. It is the supercharger isolator.

Hello ninsecgt,

Sorry you feel like your hearing a strange noise from your vehicle. If this sound is unfamiliar to you, I encourage you to visit a dealer. That way we can understand if it is truly normal or not. If you decide to do so, I can help you make an appointment to have your vehicle diagnosed. Let me know, here to help.

post a video clip of the noise. I always hate to tell people noises are nothing without hearing it.

in these newer cars the injectors make quite a racked and the on this car the the supercharger isolator can make noise.

is this hood up or hood down inside the car? on my car hood down I don't really even notice anything. If I pop the hood and stand right over the pulleys there noise at times.
