[the new guy]

Definitely sounds like it’s knocking, hate to see that for you. My 65k 2014 motor did the same seemingly out of no where. I paid a dealer a diag fee who wanted to tear it down to confirm failure but at that point I knew to replace.

Here’s what I did to replace it:

Search for an engine on car-part.com

You’ll want to find:
An engine from the same model year/transmission
An engine with no cracks, tested, warranty, and ideally provides a core refund plus the cost of picking up the core included.

When my 2014 started knocking (non recall related) I paid about $2500 for the motor and another $2000 having a local performance shop do the engine swap.
