2021 Subaru Forester Whines After Shutoff

Here is a recording of the sound:

I bought this car a month ago. It has 480 miles
on it. It has an auto shut off feature when I
come to long stops. Since I got the car, it will
occasionally make this noise when I am
stopped at a stoplight and the car auto shuts
off, or when I completely turn the engine off
and exit the vehicle. There are no alert lights
on, and it happens during both short and long
trips.

I am going on a road trip soon so I took it to
the Subaru dealership today to look into the
noise. The service manager had no idea what
I was talking about, and he said they drove it
3 miles and were not able to replicate the
noise. He said a recording would be helpful if I
come in again, so I decided to record when I
got home just in case, and, with much
annoyance, I was able to capture the noise on
the first try.

The service manager said, even though he
doesn’t know what it is, I should be fine on my
road trip.

I only know the bare basics about cars. I
would really appreciate some insight, and to
know whether or not I should go back to the
dealership.
