I hear a slight humming/buzzing from the front end / wheel well after the car is shut off. (I noticed this while adding air to my tires.) It turns off after a minute or two, but I've always wondered what it is. Never had another car do that.

Any ideas?

 

Radiator fan?

 

No, more electronic sounding / piezo-like.

 

That's bizarre. I'll listen to mine tomorrow to see if I hear it.

 

It's the headlights, the LED driver hums

 

THANKS! I knew there wasn't anything wrong, but I was always wondering. This is my first car with LED lights.
