That rattling at idle.

I brought my car to Fred Anderson Nissan of Raleigh 34 days into ownership expecting some form of service under the 90 day warranty I was promised at the dealership I bought it from; only to find out that the warranty expired after 30 days. From now on, my 370 will stay far away from the dealership unless recalls pop up in the future. Not to mention, the tech stalled twice while pulling my car into the garage leaving me and the service rep laughing hysterically.

Anyhow, one tech I spoke to mentioned that it sounds like a heat shield rattle. The notes on the diagnostic sheet state "Noise may be coming from the flywheel or loose bolts, recommend breaking down the trans to find noise." I'll soon jack up the car to tighten all heat shield bolts just in case that's the issue, but I'll wait on opening the trans until I need either a clutch or a new CSC assuming the noise doesn't get noticeably worse.

The other two issues I brought it in for were warped front rotors and the infamous ECM capacitor whine. I refused to pay dealership prices on having rotors machined and everyone claimed they couldn't hear the whine at all (as expected) so I'll ignore the whine and replace or have the rotors machined once I replace the front brake pads.

I'm late to this thread, just found it trying to diagnose a similar rattling sound on my 09. One big thing though, my sound is almost identical to the two videos posted and mine is an automatic transmission not a manual transmission. This leads me to believe it has nothing to do with the any part of the clutch or transmission. My first thought is that it was something loose under the car so I jacked it up and ran the engine. I inspected and jostled everything I could put my hands on and found nothing loose or vibrating and nothing I could ID as causing the sound. I concluded it must be something internal to the exhaust, what ever that could remotely possibly be.

Curious to hear from others that suffer(ed) this agonizing rattling what is is/was. Next step is to take it over to Nissan and let them figure it out.
