The failure had become more persistent over time. During an oil change, it was discovered that the drive axle from the rear to the front of the vehicle was leaking. The vehicle was taken to the dealer; however, the dealer was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
The vehicle is exhausting leaked fluid through the vents inside cabin at 23,000 miles causing headaches and fatigue. The Power transfer unit does not allow for maintenance and has no drain plug. The unit seems to fail alot with Fords when looking online. It is dangerous for the driver to smell this inside the cabin.
