What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some 2022-2023 F-150 vehicles built on 23-August-2022 and through 30-April-2023 equipped with a 5.0L engine may exhibit an oil leak from the oil filter adaptor to engine block mounting area. This may be due to block porosity just below the oil filter adapter near the main bearing cap outer bolt. To correct the condition, follow the Service Procedure to inspect the engine block for a porosity leak.

Read by machine from the document NHTSA serves (3 pages), read Sep 30, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 2 model years this bulletin names have filed 1,333 complaints with NHTSA since 2015.
On the 2022 Ford F-150, the 13 owners who gave an odometer reading for Engine reported it at a median of 12,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I purchased the truck 2 weeks ago brand new and it has a total of 570 miles on it. After not being used for one day, the truck would not start at all. I receive a warning indicating that I should stop safely now, that full power accessory mode is on and a check engine light. I connected a OBD scanner but no codes were generated.

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 TSB 23-2194 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 23-2194 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 23-2194 cover?
The manufacturer filed it against 2 model years: 2023 Ford F-150, 2022 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2022-2023 F-150: built 23 Aug 2022 – 30 Apr 2023 — the build date is on the certification label in the driver’s door jamb.
