I've been hearing this grinding noise from the rear of the car. It's sounds like it's near the wheels towards the middle of the car. If I stab the throttle around 20-25 mph any mode, gears 2-4 is where I hear it the most. Haven't tried higher speeds as of yet. I'll see if I can get a video it's clearly audible with the windows down. The car has 35K miles.

Grinding like debris in the differential? Or grinding like muffler pipes scrubbing against the car body?
Better rack the car and take a peek from underneath to see if anything is loose like muffler brackets, heat shields, etc.
while it’s on the rack, pull the fill plug on the diff and see if fluid level is correct and color is good.

Have you had your diff serviced yet? That's due at 25/30k miles.

Yeah I had my service that inclouded the diff service at 33K. Today the noise is hardly audible. Even hard to replicate. Yesterday was a lot louder and very easy to replicate.
