What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThe affected vehicles have a Powertrain Control Module (PCM) calibration that could, over time, reduce the effectiveness of the emissions control system and the monitoring accuracy of the catalytic converter’s efficiency. As a result, the Malfunction Indicator Light (MIL) may illuminate for low catalyst efficiency even though a catalytic converter repair may not be necessary.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 4,417 complaints with NHTSA since 2015. 2,130 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2018 Ford F-150, the 334 owners who gave an odometer reading for Power Train reported it at a median of 60,350 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
10 speed transmission hazards: when braking the transmission lunges into to lower gears and surges forward erratically requiring varying brake pressure to stop. Acceleration is also erratic, sometimes delayed, sometimes immediate. The Ford dealership does not have a solution and Ford will not responds to calls.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 24E12 a recall?
No. A emissions communication 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 24E12 repair free?
A emissions communication is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 24E12 cover?
The manufacturer filed it against 3 model years: 2020 Ford F-150, 2019 Ford F-150, 2018 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
