Ford filed this with NHTSA as a service bulletin dated Apr 4, 2024, received Apr 24, 2024, about the engine. It names 1 model year (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.

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 2024 Bronco Sport vehicles built on or after 11-Mar-2024 equipped with a 1.5L engine may exhibit a coolant system fill above max line by about 10 mm - 12 mm in the degas bottle with the engine cold. This was intentionally done at the assembly plant to increase cooling system pressures. If the coolant system level is over the max line by about 10 mm - 12 mm, do not remove coolant in an effort to adjust or lower the coolant level in the degas bottle.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52415 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 52415 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 52415 cover?
The manufacturer filed it against 1 model year: 2024 Ford Bronco Sport. 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 Bronco Sport: built on or after 11 Mar 2024 — the build date is on the certification label in the driver’s door jamb.
