Why is my hood vibrating/rattling while the car is idled or at a complete stop?

What is your question?

When the car is idling I my hood is rattling or vibrating. When I open the hood I no longer hear it. My car recently was heat while it was parked. The bumper and grille had to be replaced. They painted the hood and fenders to blend with the bumper but I’m not sure if the body shop removed the hood to paint it. I don’t know if it’s a motor mount, transmission mount, hood hinges or the hood needs to be aligned. I only hear the rattling/vibration when the car is in idle or when I’ve made a complete stop at a red light or stop sign. When the car is moving the noise goes away. Other than that I haven’t had any problems with the car.

How long has your 2018 Ford Fiesta had this problem?

After the car was repaired. Maybe a few months
