The right rear brake caliper locked up twice, resulting in a burned up brake assembly. Car was out of commission for a long time because replacement parts could not be found by the dealer. Brake rotors are not even stocked by aftermarket manufacturers, and are extremely hard to find. Ford does not carry them.
Almost every lamp has been replaced on the external lights. The license plate light is extremely hard to replace, because the trunk lid liner has to be removed and cannot be reinstalled without new fasteners. The taillight assemblies have to be removed completely from the car to replace the lamps.
The battery had to be replaced after about a year.
The air conditioning doesn't put out a lot of air, leaving you with a feeling of suffocation on a warm day.
The oil change warning cannot be reset even after changing the oil. This prevents the odometer reading from appearing.
The AWD light is on frequently, and there is a loud clunk in the drive train when taking off from a stop.
The power steering pump has always made a whining noise since new.
The six CD changer has ruined several CDs, and is unreliable.
The windshield is at such a low angle from vertical, that the dashboard is constantly reflected in the glass, and it is extremely hard to see through the reflection, especially on a sunny day, although at night this is a severe problem. The only solution might be to place a non-reflective cover on the dash, but that is doubtful. The windshield angle needs to be raised significantly to correct this hazardous condition.
There is a lot of understeer in the steering, and the suspension is very stiff, resulting in an uncomfortable ride.
And lastly, there have been several instances of the electronic accelerator surging unexpectedly at the wrong time at low RPM, such as parking in the garage.
