Just regular 87 but I need to force a downshift to prevent it from knocking if I roll on the throttle with the transmission in D.

Its a 2021 with 4500 miles that has been only on the street. I doubt there is anything wrong, plugged or worn out.
I plan to make service request with this knocking on my list along with the rare intermittent stalling.
