Hello there, many faults will cause your 2009 Ford Flex to have a squeaking noise around the belt area. The most common faults are a failing serpentine belt, belt tensioner, idler pulley, alternator, or power steering pump pulley. In order to avoid any unnecessary repairs, have a qualified technician such as one from YourMechanic diagnose your belt noise and make any repairs required.
