Ford bulletin SSM 51120
What it saysSome Ford and Lincoln vehicles may exhibit noise when the brakes are applied. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Oct 6, 2022, received Oct 11, 2022, about the service brakes. It names 85 model years (2016–2022). 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 communicationSome Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00.

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
Source: NHTSA complaint databaseOwners of the 71 model years this bulletin names have filed 40,768 complaints with NHTSA since 2015. 1,597 of them name Service Brakes — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2016 Ford F-150, the 258 owners who gave an odometer reading for Service Brakes reported it at a median of 36,098 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The collision avoidance system has braked hard on me three (3) times when there wasn't a car in front of me. The first time a car had already turned right onto an intersecting street, the second time a car had turned left into a driveway and the driver was already getting out to get his mail, and the third time a car had stopped in the…
2018 Ford Mustang · Service Brakes · filed with NHTSA Apr 19, 2018 · ODI 11088966
As I was driving my car locked up and I had to hard break. I took it into the shop and they said it was a wiring issue and not covered under warranty. They couldn't explain why it would happen and suggested I placed something heavy on my passenger dash. It sounds similar to another recall I saw but my car is not listed as needing that

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51120 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 51120 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 51120 cover?
The manufacturer filed it against 85 model years: 2022 Ford Bronco, 2021 Ford Bronco, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport, 2022 Ford E-Series, 2022 Ford Edge and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
