Ford filed this with NHTSA as a service bulletin dated May 16, 2023, received May 23, 2023, about the equipment. It names 2 model years (2021–2022).

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

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2021-2022 Bronco Sport vehicles may exhibit a condition where the low beams turn on by themselves while the vehicle is OFF for 10 or more minutes with diagnostic trouble code (DTC) B1533 stored in the body control module (BCM). This may be due to the internal logic within the headlamp switch. To correct this condition, replace the headlamp switch (service base PN: 11654). Refer Workshop Manual, Section 417-01.
Trouble codes it names: B1533

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 SSM 51645 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 51645 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 51645 cover?
The manufacturer filed it against 2 model years: 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.
