Ford filed this with NHTSA as a service bulletin dated Apr 27, 2025, received Apr 30, 2025. It names 2 model years (2024–2025). 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
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 of the vehicles listed in the model statement with approximately 1,000 miles (1600 km) or less on the odometer, may exhibit an intermittent momentary moan noise with an associated vibration when traveling an uphill grade at 50-70 mph (80-112 km/h), while the throttle pedal is slightly depressed (throttle tip-in) without shifting. The vibration may be felt through the accelerator pedal, through the driver's side floor of the vehicle and the steering wheel that lasts for 1-2 seconds. This may be due to momentary excessive slip of the torque converter lock up clutch within the front hybrid drive unit.

Read by machine from the document NHTSA serves (2 pages), read Sep 29, 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.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 25-2174 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 25-2174 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 25-2174 cover?
The manufacturer filed it against 2 model years: 2025 Ford F-150, 2024 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: 2024-2025 F-150: built on or before 25 Mar 2025 — the build date is on the certification label in the driver’s door jamb.
