Ford bulletin TSB 25-2446

What it saysThis article supersedes TSB 23-2316 to update the Service Procedure and labor operations from M-Time to AP-Time and add a limit. NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated Sep 19, 2025, received Sep 23, 2025, about the electrical system. It names 2 model years (2022–2023). 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

This article supersedes TSB 23-2316 to update the Service Procedure and labor operations from M-Time to AP-Time and add a limit. Some of the vehicles listed in the Model statement above, may exhibit an illuminated powertrain temperature warning lamp accompanied by a "Motor Coolant Over Temperature" message in the instrument panel cluster (IPC) with DTC P0A3C:94 stored in either the secondary on-board diagnostic control module B (SOBDMB) and/or the secondary on-board diagnostic control module C (SOBDMC). This may be due to the software within either the SOBDMB and/or SOBDMC.

Labour operation and the time the manufacturer allows

Read by machine from the document NHTSA serves (2 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 database

Owners of the 2 model years this bulletin names have filed 1,333 complaints with NHTSA since 2015. 753 of them name Power Train, Electrical System — 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 F-150, the 55 owners who gave an odometer reading for Power Train reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Passenger side rear axle retention bolt sheared off. Discovered during routine maintenance / tire rotation. Unknown how safety was at risk -- dealer told me once discovered that the vehicle would be repaired under warranty, and they could do in 24 hours, so no discussion about unsafe to drive as others have reported they were told.

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 579.5

Is Ford TSB 25-2446 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 25-2446 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 25-2446 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.
