Rattle in the rear of my 2022 Tahoe High Country

I have a 2022 Chevy Tahoe high country 6.2 L 2 Wheel Dr. every time I hit a speed bump or go over a bump. There’s a thump rattle in the back end of my vehicle. I have looked everywhere and had mechanic search and we cannot find it anybody else experiencing this?

Do you have the option for the safe in the center console? I was hearing a "thunk" that I couldn't identify that sounded like it was coming from the middle/rear of the vehicle and by accident discovered if I left the console safe unlatched, it would open and close when going over bumps and since it was in the closed console, it sounded like it was external to the vehicle. As long as the save is at least latched, the noise magically disappeared....

Check in the rear of the Tahoe. There is a secret compartment in the back where the jack is located. Make sure that everything is strapped down and not rolling around under the floor in the back. One time I had an umbrella rolling around that was not strapped down and it was driving me crazy.

I had a metallic rattle coming from the rear of my 2021 suburban at low speed over bumps and uneven terrain that started after about 1 year of ownership. Every oil change I would inspect under the car for loose exhaust shields or other potential sources for the rattle. Finally last oil change, 5 years into ownership, I found the rattle. A crushed aluminum can had found its way into the U shape of one of the lower rear control arms. It was wedged in next to where the lower shock mount is. I Removed the can and no more rattle from the rear of the vehicle.

Check the levers on the second row seats that control the seat moving forward and aft. I had a rattle I couldn’t pin point and found it to be the lever which needed tightening.
