Ford filed this with NHTSA as a manufacturer communication dated Jun 1, 2026, received Oct 3, 2025, about the engine — 2 documents under this number. It names 14 model years across Ford and Lincoln (2023–2026).

Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (18 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 14 model years this bulletin names have filed 903 complaints with NHTSA since 2015. 172 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.
The contact owns a 2026 Ford Bronco Sport. The contact received notification of NHTSA Campaign Number: 26V548000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.
2026 Ford Bronco Sport · Engine · filed with NHTSA Sep 8, 2026
In Lincoln's own words the lithium batteries are flawed and can cause a short circuit which can lead to a fire. This could lead to grave danger to life. I keep my car in my garage which could lead to a house fire and harm to my family. Their original temporary fix was to set the charging system to stop at 80%.
2024 Lincoln Corsair · Engine · filed with NHTSA Sep 9, 2026
On May 10 a lighted wrench appeared on the instrument panel. The car felt as if I was loosing power. May 12 I got in the car, the wrench and check engine lights were both on. Called the dealer service department. They told me the car is not safe to drive as it cannot accelerator and will go into "limp mode".
2023 Lincoln Corsair · Engine · filed with NHTSA Jul 6, 2026
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 25B33 a recall?
No. A manufacturer 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 25B33 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 25B33 cover?
The manufacturer filed it against 14 model years across 2 brands (Ford and Lincoln): 2026 Ford Bronco Sport, 2025 Ford Bronco Sport, 2024 Ford Bronco Sport, 2023 Ford Bronco Sport, 2025 Ford Escape, 2024 Ford Escape and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
