Very odd sound, not normal at all.

Strange, but after watching your video, I feel like I have also heard this before in my 2013. I could be crazy; will verify the crazy tomorrow.

I have a May 2012 built 370Z here in Australia, definitely no clank clank sounds as you've recorded in the video - neither my 350Z from six years ago ever had this noise!

Once you hear the sound, you can't "unhear" it. It does it consistently too. Vicster...I think we all should sanity check now and then.

While we're on the issue of noises, I notice that the 370Z idling noise is not as smooth as the 350Z, it's more like a tractor idling with metallic noises inbetween - especially when the aircon is turned on - I thought of taking it back to the dealer but after a while I started to appreciate the tractor like idling noises!

Subframe bushings?

I had that exact same issue with my Evo IX. The clunk would happen, while backing up and I applied the brakes. The issue was diagnosed as the brake pads "shifting", due to the lack of shims. I replaced the shims and the clunk was gone!

You just have new car anxiety.

My 7AT was doing this for a while and it was driving me nuts, only low speeds, and very loud. I happen to get a nail in one of my rear tires and when getting it patched the tech noticed my TPMS was missing. It was inside the wheel.

My light never came on beacause it was still transmitting LOL! After we took it out no more clunk.

Checked the camber arm bushing? Worth a shot.

:iagree:I had the same problem with my 04 Quest minivan and it was due to shifting brake pads in the carrier when you shift from reverse to drive or sometimes drive to drive. Lubed up back of pads and tab slots with high temp brake lube worked for a period of time...Knowing what the noise was reassured me of no serious problems so when the noise returned some time later didn't do anything till brake change.

Sound like the pads are worn or loose in the caliper or even a loose bolt holding a caliper.

Have they chandelier the pads?

Don't think its a worn/loose pads...they checked the brakes thoroughly.

Looking at the service notes more - they listened to the rear suspension components with chassis ears while braking and found noise most noticeable from the right rear upper control arm. They replaced the arm and noise is still present.

I had the exact same thing in my Benz. Come to think of it... that noise is almost identical.
I had aftermarket pads, went back to OEM and the clunk was gone.
The aftermarket ones didn't fit as well resulting in a clunk.

Same here, I put RB500 pads on my Brembo's. Since they were really thick, couldn't put the shims on. Once the pads wore down a little, they started to "shift" causing the clunk. Put new shims on and the clunk was gone.
