It sounds like you may have a bad tank of gas if no other changes have been made to the vehicle. You may have also filled up with 87 instead of 91 octane.

Or something has come loose in the engine bay, or the exhaust is hitting the sub frame.

Tank is half and nothing noticeable is hitting the engine or sub frame, could it be the knock sensor?

Can you hear any audible knocking? Look in the engine bay for anything loose.

I would recommend that you take this to your tune rand have them look at it as you may have a mechanical problem if you are suddenly getting large amounts of knock with no changes.
