Anyone else have this problem, this is one of MANY that i have and im starting to tire of the ever growing list of problems my new car has. Not happy...off to the dealer

That sounds horrific. To my ear, it sounds like big end bearing noise and something within the combustion chambers - even possible that the higher pitched ticking is one of the pistons hitting one of the valves - either that, or there is a broken piston ring flapping around in there.

I would hazard a guess that the clever 'oil pump only runs when it needs to' mechanism isn't working, and your engine isn't getting its oil supply. If this is the case, then running it like this would be destroying the engine. When oil supply comes back, the noises would quieten down, but the bearing surfaces would be badly worn by then .......

Does this noise stop suddenly when it does stop, or does it just fade out gradually?

Take it to your dealership, with this video, and leave it there until they have fixed it or replaced the engine ...........
