What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2021-2026 Mustang Mach-E vehicles may exhibit an illuminated brake warning indicator with diagnostic trouble code (DTC) C1013:92 stored in the anti-lock brake system (ABS) module. This may be due to brake pads being out of specification for compressibility, which can alter the brake system's pressure-volume and falsely indicate an internal hydraulic failure. The pinpoint test for C1013:92 in the Workshop Manual (WSM), Section 206-09 has been updated to include a preliminary inspection and a brake pad swap to determine if an out of specification set of brake pads are the root cause.
Trouble codes it names: C1013

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 680 complaints with NHTSA since 2015. 367 of them name Electrical System, 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 2021 Ford Mustang Mach-E, the 17 owners who gave an odometer reading for Electrical System reported it at a median of 30,696 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2023 Ford Mustang Mach-E. The contact stated while driving approximately 35 MPH, a MIL warning illuminated, with the message “Immediate Loss of Power” displayed. The contact stated that the vehicle shut off and the battery was drained. The contact stated that the vehicle stopped and independently shifted to park(P).

After charging for the first time at a DC fast charge station to 80%, I resumed my trip and drove about 3 miles to merge onto the expressway, my screen panel said "safely stop now", with a turtle logo and battery icon coming on. my car then came to a complete stop within a few seconds in the middle of the on-ramp leaving me stranded.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 55242 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 55242 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 55242 cover?
The manufacturer filed it against 6 model years: 2026 Ford Mustang Mach-E, 2025 Ford Mustang Mach-E, 2024 Ford Mustang Mach-E, 2023 Ford Mustang Mach-E, 2022 Ford Mustang Mach-E, 2021 Ford Mustang Mach-E. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
