  POWER TRAIN:DRIVELINE:DRIVESHAFT · STRUCTURE:FRAME AND MEMBERS:UNDERBODY SHIELDS

  Ford Motor Company (Ford) is recalling certain 2017-2022 F-250 and F-350 Super Duty vehicles equipped with gasoline engines and aluminum driveshafts. Underbody heat and noise insulators may loosen and contact the aluminum driveshaft, which could damage the driveshaft and cause it to fracture.

  Risk: A fractured driveshaft can cause a loss of drive power, or a loss of vehicle control if the driveshaft contacts the ground. Additionally, unintended movement could occur while parked if the parking brake is not engaged. Any of these scenarios can increase the risk of a crash.

  Remedy: Dealers will inspect and repair the driveshaft as necessary, and properly attach the underbody insulators, free of charge. Owner notification letters were mailed on April 7, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S09.

  POWER TRAIN:AXLE ASSEMBLY

  Ford Motor Company (Ford) is recalling certain 2020-2021 F-350 Super Duty pickup trucks equipped with 6.7L diesel engines and Dana model 275 rear axles. The rear axle housing may not support the load of the pickup truck and deform, which could result in driveshaft separation.

  Risk: Driveshaft separation may result in a loss of drive power, or unintended vehicle movement if the vehicle is in park without the parking brake applied, increasing the risk of a crash.

  Remedy: Dealers will inspect the axle housing for deformities, and repair or replace the housing, as necessary, free of charge. Owner notification letters were mailed on September 3, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall 21S31.

  Ford Motor Company (Ford) is recalling certain 2020 Super-Duty F-250, F-350, and F-550 diesel pickups. The transmission torque converter damper plate was not tempered, resulting in a brittle damper plate that may fracture and cause the engine to stall or require increased brake pedal effort in order to stop the vehicle.

  Risk: An engine stall or requiring additional braking effort to stop the vehicle can increase the risk of a crash.

  Remedy: Ford will notify owners, and dealers will replace the transmission assembly, free of charge. This recall began July 6, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S33.
