We frequently notice a clicking noise emanating from our 2020 Ford Explorer, even after it has been stationary for a few days. The sound seems to be originating from underneath the hood and occurs multiple times throughout the day, beginning with a click and then a rumble. What could be causing this issue?

★ Top Answer

Typically, if you hear a clicking sound coming from your Ford Explorer even when it hasn't been driven recently, it is likely due to a solenoid. These solenoids, along with various valves in the engine compartment, may open and close even when the vehicle is not in operation. If the clicking noise persists after the car has been idle for days, it could signal a solenoid issue. It is advisable to have this checked by a dealership to ensure that there are no underlying computer malfunctions causing the solenoid to activate sporadically. If left unaddressed, this issue could potentially drain your battery over time and hinder your ability to start the vehicle.
