Ford Super Duty diesel may not hold Park

NHTSA campaign 22V256000 · Reported 2022-04-14 · Ford Motor Company

high How serious is it? About this label

A heavy truck rolling away with nobody in it can seriously hurt people or damage property, and while the notice does not tell you to stop driving, you should set the parking brake every time you park until the transmission is repaired.

What's wrong, in plain English

A small washer inside the automatic transmission can break apart, and the metal pieces can get lodged in the parking mechanism, the part that locks the transmission when you shift into Park. If debris jams it, the truck may never fully go into Park or may slip out of it, and can roll away after you step out. This affects 2020 Super Duty trucks built with the 6.7-liter diesel engine. The dealer replaces a gearset inside the transmission.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your truck is covered (Ford's recall number is 22S22).
2. Contact your Ford dealer or Ford customer service at 1-866-436-7332 to book the transmission repair.
3. The repair costs you nothing; until it is done, use the parking brake without exception.
