It sounds like a rod is knocking or something else if the sound is metallic or a metal sound chances are it's a rod knocking, dropped valve or other in the head or block. Would help if someone could look at it just explaining it one can only make a guess.
Pinging is from to low grade of octane I don't believe your vehicle requires high octane.

the knock, is it a clicking noise like metal on metal? Is it an engine knock as in it idling poorly? I would do some common maintenance on it, like changing the oil, checking the transmission oil level, maybe change spark plugs and air filter. Then see if you still have the same noise. Actually all this is to try to pinpoint where and what it could be. It could be an engine problem, or transmission. Good luck!

warranty? maybe! see the dealer first! could be a rocker or lifter? could even be a flywheel bolt. have the professionals check it.
