What the bulletin says

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 1 model year this bulletin names have filed 618 complaints with NHTSA since 2015. 166 of them name Engine — 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 2022 Ford Maverick, the 18 owners who gave an odometer reading for Engine reported it at a median of 18,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
This vehicle was purchased in 2021 with a 3 year 36k mile warranty. At 39k miles the truck has started to shut off randomly while driving. It has put us in very dangerous situations and it happens multiple times every day. The vehicle will be driving down the road and suddenly shut off.

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 23L04 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 23L04 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 23L04 cover?
The manufacturer filed it against 1 model year: 2022 Ford Maverick. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
