What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 Mustang vehicles may set diagnostic trouble code (DTC) U211B:87 in the ABS module during a diagnostic self-test. This may be due to the ABS module's DTC sensitivity during vehicle key-on/start-up. To correct the condition, reprogram the ABS module using the latest software level of the Ford Diagnosis and Repair System (FDRS) diagnostic scan tool. For claiming, use the causal part number 2005 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 81 complaints with NHTSA since 2015. 7 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.
I was slowly backing out of a parking space at the Circle K gas station on July 3, 2024, on Battleground Avenue in Greensboro, NC, and applied the brakes when the warning alert sounded that there was cross traffic. I immediately applied the brakes, but to no avail.

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 579.5Is Ford SSM 52242 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 52242 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 52242 cover?
The manufacturer filed it against 1 model year: 2024 Ford Mustang. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
