Rattle sound never experienced prior to maintenance check at Toyota

Agreed.

Reach in behind the engine and see if you can wiggle the exhaust manifold heat shield. Mine rattled horribly with foot on brake at stop lights when its mounts had finally deteriorated. If it is still firm, crawl under the car and see if any of the other shields placed along the exhaust route are loose.

You wouldn't be able to take a picture so I can see exactly where to look ?

When the car is in neutral or reverse there is no sound.

When driving for a while then putting the foot on the brake, the rattle sound begins or simply just reversing a few inches when the car is running in a parking lot then driving a few inches followed by putting the foot on the brake the sound will begin.
