Engine stalls.

What is your question?

A couple a days ago my car would not go forward after I put in (D) drive. It would make a humming noise when I gave it gas, why didn't the car change into another gear? It was a 2021 Kia Sorento.

What makes this problem better or worse?

When I start to drive forward.

How long has your 2021 Kia Sorento had this problem?

A couple a days ago.
