Got my first check engine light under 36k miles, 2022 compass

Pretty wild that it’s already showing up, unless it’s common in compass vehicles. I’m having it scheduled to look after but I hope I don’t need to pay since it’s still under warranty.

This is something to add but it may the cause of the check engine has anyone noticed a weird humming after letting go the gas when driving at 40-50mph? I can describe it as a revving noise but no RPM increases, it only goes away once it’s lower mph or I have the gas pedal pressed.
