2020 Ford F-550

The defect

Ford Motor Company (Ford) is recalling certain 2020 F-550 and 2021 E-350 and E-450 vehicles. The rear axle differential fluid may be below the minimum level, possibly resulting in a failure of the rear axle assembly and driveshaft separation.

The risk

If the driveshaft separates, there may be a loss of drive, increasing the risk of crash. Additionally, if the parking brake is not applied, unintended vehicle movement can occur and increase the risk of injury or crash.

The remedy

Ford will notify owners, and dealers will inspect the rear axle differential fluid level and adjust it, or replace the rear axle as necessary, free of charge. The recall began March 19, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S09.

The defect

Ford Motor Company (Ford) is recalling certain 2018-2020 F-150 and 2019-2020 F-250, F-350, F-450, and F-550 Super Duty pickup trucks, and 2018-2019 Ford Explorer, 2019-2020 Expedition, and 2020 Escape vehicles equipped with driver and/or passenger's manual front seat back recliner mechanisms. Also included are certain 2020 Ford Explorer and Lincoln Aviator vehicles equipped with rear outboard seats and manual seat back recliner mechanisms. The recliner mechanisms may be missing the third pawl required for seat back strength, resulting in a loose seat back. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 202, "Head Restraints" and 207, "Seating Systems."

The risk

A seat back with an improperly assembled recliner mechanism may have reduced strength and may not adequately restrain an occupant in a crash, increasing the risk of injury.

The remedy

Ford will notify owners, and Ford and Lincoln dealers will inspect the seat structure and replace them, as necessary, free of charge. The recall began October 21, 2019. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 19C07.

the diesel fuel system, the fuel system

The Office of Defect Investigations (ODI) has received 27 complaints alleging diesel fuel leaks due to a fracture in the secondary fuel filter housing in model year (MY) 2015-2021 Ford Motor Company (Ford) F-250, 350, 450, and 550 Super Duty vehicles equipped with 6.7L diesel engines. Of these complaints, 12 describe an engine compartment fire. The proximity of the secondary fuel filter to high heat sources creates a potential for autoignition thermal events and fires. ODI has contacted the vehicle manufacturer, Ford, and the filter manufacturer, Allevard Sogefi USA (Sogefi), and learned that the low-pressure fuel system is capable of a maximum operating pressure of 8.5 Bar, while the secondary fuel filter is only tested to seven (7) Bar during the manufacturing process. Additionally, changes starting in 2022 by both Ford and Sogefi align with a lack of similar complaints on MY 2022 and newer vehicles. ODI is opening this Preliminary Evaluation (PE) to evaluate the severity of the potential problem and to fully assess the potential safety-related problems.
