20V099000 Feb 21, 2020 POWER TRAINFord Motor Company (Ford) is recalling certain 2020 F-550 and 2021 E-350 and E-450 vehicles.

Summary: 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.

Consequence: 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.

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.

Vehicles covered (all models): 319

Summary: 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."

Consequence: 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.

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.
