Part Identification

cbsimmons2 said:

I’m new to my First Edition, and not mechanically inclined so bear with me. I am hearing a “motor running” sound from this part above spare tire underneath the truck. I tapped on the light gray cover looking piece and it stopped. Can someone tell me what this part is under here? And should it be humming/making noise while it’s been off and in my garage for many hours?

I’ve also had a pop up in dash saying Maintenance Required Soon but no other information. Not sure it’s related but wondering how I am supposed to know what maintenance is due with such a broad message?

Thanks in advance.

Hi CBSimmons2, Good morning.
After I had 5000 miles, I saw that maintenance Required advisory. Dealership rotated tires and topped off fluids. Oil Change is done at 10 k miles. Toyota calls this Express Service.
