What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2022-2023 Explorer vehicles equipped with a 2.3L engine may exhibit an intermittent malfunction indicator light (MIL) with diagnostic trouble code (DTC) P1026 and/or P1299 present in the powertrain control module (PCM) and an engine over-temperature message displayed on the instrument panel cluster (IPC) after a cold engine start. The vehicle will also exhibit reduced performance when it enters fail safe cooling open loop mode. If the engine is not overheating, clear the DTCs to reset the fail safe cooling open loop mode. Start and idle the engine while viewing coolant flow at the top inner (engine side) degas bottle hose port through the semitransparent top. If there is no coolant flow, replace the L1MZ-8A365-AAD engine-to-degas bottle hose. If if there is any coolant flow, return to Workshop Manual (WSM), Section 303-03A diagnostics.

Read by machine from the document NHTSA serves (1 page), 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 381 complaints with NHTSA since 2015. 116 of them name Power Train, 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 Explorer, the 14 owners who gave an odometer reading for Power Train reported it at a median of 26,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2022 Ford Explorer. The contact stated that while driving at various speeds, the engine randomly disconnected from the transmission and the vehicle started idling while losing motive power while attempting to accelerate. During the failure the message "Brake Applied; Power Reduced" was displayed.

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 SSM 51756 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 SSM 51756 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 SSM 51756 cover?
The manufacturer filed it against 2 model years: 2023 Ford Explorer, 2022 Ford Explorer. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
