Odd thumping noises from under the hood WELL after the vehicle has been turned off.

Mine makes a variety of minor noises for at least an hour after any interaction with the vehicle. Solenoid or relay clicking and humming fans mostly.

I was wondering the same thing with mine. I'll go into the garage, open the door of my bronco sport to get something, close the door, and hear clicking and mechanical noises from under the front hood. Feels like all the action will drain my battery.

That's why I connected a Battery Tender. No more worries about battery status. If you drive every day, I don't think you should be concerned.

Could it be the brake vacuum booster binding and moving as vacuum leaks down?
