Metallic Clank Sound

Good Day All,

I have a 2020 AWD GT1 with approximately 1250 miles on it.
When I’m going around 40mph or higher and go over a moderately sized bump/joint crack in the road where the rear of the car hops/goes straight up and down I am hear a metallic clank sound.
I have not heard it if only one rear tire hits a nice size bump; it has to be both tires.
While driving on somewhat less bumpy roads, the car is relatively quit.
I checked the spare and battery area with both of those items being tight.
The exhaust seems pretty tight.
Not sure if my car is experiencing the infamous rear hatch issues which I thought were fixed by now?
I have a dealer visit this Thursday, but was looking for some possible opinions from you.

What’s the psi on your rear tires? I remember seeing someone had that exact problem and the psi was at like 50 still from the dealer. They said it went away after it was aired down to the correct pressure

I keep the pressure per what the door plate says, and that would 38psi in the front and 36psi in the back.
I have had the car since 2/2020 and check my tire pressure once a week, but thank you for the suggestion.

And everything in the spare tire area has sufficient force on it so that it won’t move? Do you have car seats in the back?

No, I do not have car seats in the back.
The sound seems to be coming at the rear of the car.

I messed with the two rubber stoppers on either side of the hatch and unscrewed them practically all the way out which seems to have worked.

Take the alignment bracket of the rear hatch an put washers under them then screw those rubber bump stops all the way in & turn out 1 1/4 turns....

I had this in both my stingers... 2019 and 2020... it's coming from the console area 100%
Both cars have this rattle knocking type sound coming right from that area... where the thermostat controls are.
Any hints folks?

Could be an adapter isn’t fastened down. So it’s moving like coins in your cup holder

I think after sometime has gone by, I think I have pinpointed where the noise is coming from which is the rear passenger seat; driver side rear is fine while up.
After dropping the seat and driving around in and around my neighborhood, the sounds that I have heard are gone when the seat is up.
I’ll assume the noise while the seat up is coming from the rear seat latch mechanism, and when I go over a moderately sized bump there is some movement.
