2022 noise from spare tire area?

I was in the garage and noticed like a noise that sounded like a little air compressor sound coming from the rear of the car. Climbed underneath and it is coming from the spare tire area. Then it stopped. Any idea what that is? The car has been sitting for 6 hours. I just happened to go to the garage and heard it. Then it stopped

 

Fuel pump. It’s fine

 

It's normal. There is a section in the owner manual that talks about it.

 

Its gonna blow up.

 

Duck and cover. It's the self destruct sequence

 

Thank yo!

 

It’s not the fuel pump if the engine is not running. There’s an air vacuum pump that runs periodically to test the integrity of the evap system.

 

The manual mentions this.

 

yeah that’s what I said

fuel system. Same shit.
