Clunking coming from the trunk?

Recently I've noticed an almost clunking coming from the trunk.

There is nothing behind the seats, in the trunk, or in any of the storage compartments that could cause a clunking.

It's a very "light" clunk. Is it possible it is some kind of pump?

Recently I've had a ton of problems with my ABC suspension. The red light was coming on and I took it into the shop. They told me that they could not find anything wrong. Then a few days ago, I had trouble getting the car to rise. 1,2, or even 3 sections of the car would not raise. The problem seems to have fixed itself...for now.

What kind of noise does the ABC pump make? Is it the source of m clunking?

No idea if my car ever had this issue fixed.

What does the gas tank baffle issue sound like?

Yup. I filled up the tank and it went away. I burnt though 1/4 of a tank driving across town and back and it's clunking again.

Warranty coverage time. LOLZ

Have your mechanic check whether the subframe bushings are cracked.
