Noise or Vibration upon Acceleration from under rear center of car

Hi, I'm a newbie with a 2015 Jeep GC SRT with 58 miles on it. I took delivery a couple days ago. Love the car, but am experiencing a disconcerting noise on acceleration. It sounds like a metal on metal sound, but can't tell if its a vibration or something rotating - but does not sound good. From 0-25mph, when accelerating more aggressively, there is a very loud noise coming from under the rear, center passenger seat area. It does not happen if I leisurely accelerate - only with more aggressive acceleration. It gets louder if I drive harder. It only happens in low gears and usually 0-25 mph range. Dies out after a second or two.
I have switched from Auto to Sport mode, but makes no difference.
Made an appointment at dealership to go back, but have to wait a few days to get in. Wondering if anyone has a thought. Worried its transmittion or transfer case or just something vibrating that should be adjusted....

Could be the transfer case or the drive shaft. Bring it in asap.
Good luck and let us know the outcome.

Good News. Dealer located a vibration at a certain speed - vibrating from the exhaust to a support. The fix was a rubber washer between. Feeling a whole lot better. The dealer was worried regarding the sound that it may be much worse when test driving the car.
