Lincoln MKX PTU failure with leaking issue and noise under driver's side on Lincoln MKX

Some Lincoln MKX owners report experiencing PTU (Power Transfer Unit) failures characterized by leaking issues and noise under the driver's side. These issues include PTU seal leaks that lead to fluid escaping from the PTU area, which is a common problem noted among MKX models. Additionally, some drivers have reported hearing loud grinding and intermittent noise from the PTU, particularly at speeds around 35 mph. To mitigate PTU failure, it is recommended that fluid changes occur at intervals of 30,000 miles or less, with some suggesting annual changes for optimal maintenance. Furthermore, changing the PTU fluid every 20,000 to 50,000 miles is advised to prevent failures caused by old fluid and excessive heat. Owners experiencing these concerns are encouraged to address the PTU seal leak and seek professional assistance to resolve any accompanying noise issues.
