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.
