My 2020 ST started knocking 2 days ago on morning cold start.

Good evening, all, I had my Explorer ST for almost 2 years and loving it until a few days ago. I have a bad knock right off idle up to 3500rpm. Wont do it under load, seems to run perfect but dont want to drive it if its a rod knock. Trying to get the dealer to pickup and diagnose. What you guys think ?

First things first…how much oil is in it.
Second things second…rod knock won’t go away as rpm goes up…it’ll get worse.

Thank you thats what i thought, but it was a quart low when i checked, checked oil pressure with a obd scanner, it only 16.65 psi

Okay started my truck this morning, to get ready for the dealership to pickup knock still there at idle, but not in gear and oil pressure 28.65 idling. Still going in for LH exhaust leak recall and hope they can figure out the knock
