No chirps here. Does sound like a belt. Does it vary with RPM?

No chirps on mine in 11K miles. Usually a belt or pulley bearing.

Try taking the belt off and see if it still chirps then ull know. Make sure the pulleys spin freely without any noise as well.

btw, I love how every noise the dealer hears is 'normal'. If i caught ur attn its not normal

I have a 2011 that has the "chirping" too! Only notice it at idle or just off idle.

I was trying to think of how to describe it when I take it in for the next service. "Chirping" is an excellent way to decribe it.

I've also noticed that at about 1/4 throttle and with windows down, I have a "deiseling" sound almost like a pre-detonate sound, but that shouldn't be the case with me always running 93 octane. Anyone care to weigh in on the rattling sound?

The rattling is your supercharger isolator every v does it just do a search on supercharger rattle and the threads will come up
