Ford bulletin TSB 25-2016

What it saysSome of the vehicles listed in the Model statement above may exhibit a loss of engine coolant from a leak at the coolant pump. NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated Feb 6, 2025, received Feb 11, 2025. It names 4 model years (2021–2024). 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.

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

Owners of the 4 model years this bulletin names have filed 1,361 complaints with NHTSA since 2015.

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 25-2016 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 25-2016 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 25-2016 cover?

The manufacturer filed it against 4 model years: 2024 Ford Bronco Sport, 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
