Rattling Noise coming from 2018 crosstrek

[Jstyle]

Hello,

I was hoping someone may have some guidance. I have a 2018 Subaru crosstrek that has an intermittent noise occurring only when accelerating at low speeds. I have brought it to two different mechanics to see if I can get it fixed but neither place could recreate the sound and they both stated that they could find nothing wrong with the car.
I posted a recording of the noise to YouTube.

Does anyone know what this could be?

thank you!

Have the vehicle placed onto a drive-on-rack.
1) Check the body / exhaust shields including CAT converter and muffler for internal damage
2) Check all the exhaust rubber hangers and engine / transmission mounts
3) Check all the wheels for the proper wheel nut torque
4) Check all axle flanges for the correct torque / test the axle bearings
5) Check the spare wheel mounting and any tooling associated with a tire replacement
6) Check the suspension components for wear / looseness / alignment / springs and upper mounts
7) Check the under body / outer body for damage / loose parts
8) Check the trunk and under the seats for "moving items"
9) Check the drive belts (serpentine) and rollers wheels
10) Bring the "mechanic" for a drive
