Loud humming sound under the hood
No air suspension. To me it sounds like when you turn the key to accessory and the motor starts getting primed to start, but its a lot louder- MCW94

Loud humming sound under the hood
In the morning when we unlock our Expedition with the key fob, there is a loud weird humming sound that comes from under the hood. Is there an actuator or a pump that could be cycling on before start up?- MCW94
