Ford Flex Problems
RepairPal has identified the most common problems with the Ford Flex based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The 2009-2016 Ford Flex with automatic climate control may have a problem with frequent fan speed changes when using the heater or air conditioner. Normally, the fan speed changes only to maintain a selected temperature, but when the fan speed changes frequently and needlessly, there is an issue with the fan speed control unit.
The fan speed control unit, sometimes erroneously called the blower motor resister, regulates the speed for the blower motor in order to maintain the temperature set by the driver. When it fails, the fan will run at random settings, and the climate control will be inaccurate.
Note: this does not affect the temperature of the air that comes from the vents, it affects the amount of air that comes from the vents.
The repair is simple, and quick. The control unit is located behind the glove box in most models, and removal and installation takes only minutes.
Also note: this only applies to vehicles with single or dual automatic climate control.
Defective anchor brackets for the front calipers can cause abnormal brake rotor and pad wear concurrently. Noise can be heard while braking, a grunting or grinding from the front. The caliper anchor brackets should be replaced with revised parts, and also replace the rotors and brake pads.
A leaking axle shaft seal and / or PTU cover seal can cause transmission (red) or Power Transfer Unit (PTU) (brown) fluid leaks at the axle area. The axle shaft seal and / or PTU cover seal may be leaking and should be replaced as required.
Defective materials can cause the center console latch to break. The latch on the console lid should be replaced.
Misaligned or corroded caliper anchor brackets can cause the rear brakes to drag, and make a rhythmic sound. The rear caliper anchor brackets and brake pads should be replaced.
