NHTSA recall 20V099000

What's wrong: The rear axle differential fluid may be below the minimum level, possibly resulting in a failure of the rear axle assembly and driveshaft separation.

Why it matters: 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 fix: 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.
