Net-net. Take the car back, document it, and escalate if needed. Be clear on the documentation. (Think of it this way. You go to sell that car in a year or so, a perspective buyer checks out the car and hears "the noise", and your answer is "It is normal"). What do you think will happen next.
A good dealer will fix and/or replace the item because it is covered and not at their cost, a bad dealer will say its normal to avoid it.

If you do a search and go back and read several of the early threads on the rattle, they will explain what mechanically causes the rattle and why Eaton designed it that way.
A certain amount of rattle is indeed inherent to the design of the coupler due to the way it functions.
IIRC there is a TSB that instructs the dealer as to how to determine if the noise level of the rattle is still within 'normal' design range or whether it is excessive. If they determine it is excessive, they'll replace the entire SC assembly. They'll replace the whole assembly and not just the coupler because the SC assembly itself is deemed a replacement part and will be sent back to the manufacturer.
