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.
