Ford bulletin TSB 26-2216
Ford filed this with NHTSA as a service bulletin dated May 6, 2026, received May 14, 2026, about the power train. It names 12 model years (2020–2022). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThis bulletin supersedes 25-2549. Reason for update: To add 2020 model year chassis cab vehicles. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to the software in the PCM. This condition does not affect vehicle drivability or durability.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 26-2216 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB 26-2216 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does TSB 26-2216 cover?
The manufacturer filed it against 12 model years: 2022 Ford F-250 Super Duty, 2021 Ford F-250 Super Duty, 2020 Ford F-250 Super Duty, 2022 Ford F-350 Super Duty, 2021 Ford F-350 Super Duty, 2020 Ford F-350 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
