Creaks like old wooden flooring!!

Hey guys,

I've got an unusual one. I've owned my '17 ZL1 for a little over a year now and in the past couple of months I've developed an issue, may be a structural one..but I can't make sense of why it would be considering my car is bone stock and I have had no accidents or anything of the sort...so...was wondering if anybody else has had this issue and if there is a solution.

Whenever I accelerate or brake, even worse if it is accelerating from a stand still and no matter how hard, moderate or soft I accelerate or again, while braking...I get this creaking noise...literally like old homes with wooden flooring...and it seems to be coming from the deck right behind the backrest of the rear seats. I have even dropped the rear seats and noise is even louder and more pronounced, however no idea what it could be. It also kinda sounds like when you put metal under stress and the release the stress.

Annoying as hell....so....any guess as to what it could be and what the solution would be??

I look forward to your feedback....

Thanks and regards.
