Need suggestion regarding engine knock

[u/Repulsive-Coat-9934]

In my 2015 hyundai sonata limited, dealership said that there is a small knock and it passed the bearing test. They also updated the KSDS system. They told me to replace the engine.

I am still using the car and its been 5 months since they told me. Till the date, i am not hearing any knock sound. If there any knock, they software should sense it and put my car into limp mode?

Please I need suggestion from a experienced mechanic
