Vehicle: 2021 Subaru Legacy Base 2.5i Mileage:~65,000 miles My engine suddenly began making loud internal knocking/tapping noises with no warning lights, no overheating, and no prior symptoms.

The failure happened without any warning indicators, misfires, overheating, or oil pressure warnings. All diagnostics (including compression and leakdown) were clean, and the vehicle has been properly maintained.
