Ford filed this with NHTSA as a service bulletin dated Oct 16, 2023, received Nov 3, 2023, about the equipment. It names 1 model year (2023). 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 NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Some 2023 Bronco 3-door vehicles built on 01-Jul-2023 and through 25-Jul-2023 may encounter a whistle noise from the right side A-pillar area. Inspect the window run at the sail area (triangle) for any type of deformities and/or not sitting flush. This may be due to the inner belt moulding being too long and deforming the sail moulding, compare to the driver side if necessary.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51991 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 51991 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 51991 cover?
The manufacturer filed it against 1 model year: 2023 Ford Bronco. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
