Noise coming from the rear of the 2012 QX56.

For about a year now when I first start my car there is a rattling noise coming from the rear of the truck. It last for about 1-2 minutes then goes away. Truck runs great otherwise. Is there anything I can check?

You have air shocks, right? That's the air compressor leveling the rear of the car.

take a sound clip to verify but yeah sounds like the compressor. if it gives off too much racket, something may be loose under there...

ok will look at where the noise is coming from and see if there is something loose. Thanks!

Hi again! The noise is coming from somewhere near the driver's side rear wheel. I only hear it during the first 1-2 minutes after starting the truck. After that, I no longer hear the noise until the car is turned off for about 10 min and I restart it. Attached is a sound clip of the noise that I'm hearing. Let me know what you think. Thanks!
