2024 Caligraphy Engine Knock

[GeoRich]

Hi new to the group and wanted to see if any other owners have experienced what I am with my 2024 Caligraphy. After the engine is warm I am hearing a knocking noise it is not loud but certainly noticeable and continues any time it is under load at light acceleration. It is not particularly noticeable until the car is warmed up completely. Car has 4500 miles, this began at about 3000 miles. Dealer acknowledges the noise but say they cannot determine where it is coming from. They sent diagnostics to Hyundia tech support and came back saying no problem found and that all of these 3.8l engines make this noise mine just happens to be more pronounced. Never noticed this in the first 3000 miles so I'm not convinced this is normal. They have changed oil twice, but no change. I called customer service and so far no help there. Anyone else experiencing this?
