What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2024 Bronco vehicles equipped with a dealer installed trailer tow kit may exhibit a "No Key Detected" message displayed in the IPC. This may be due to the remote keyless entry (RKE) antenna connection being left loose or disconnected during trailer tow kit installation. Verify that the vehicle is equipped with the trailer tow kit by checking the window sticker for the trailer tow kit option. If the vehicle was equipped with this dealer installed option, before performing normal diagnostics, inspect the RKE antenna connections located behind the left/rear interior quarter panel. If they are loose or unplugged, re-secure the connector(s) and retest operation. If no loose or unplugged connections are found, refer to Workshop Manual (WSM), Section 419-01 for normal diagnostics. If this vehicle does not have the dealer installed option, refer to the WSM, Section 419-01 for normal diagnostics.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 85 complaints with NHTSA since 2015. 19 of them name Electrical System — 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.
The contact owns a 2024 Ford Bronco. The contact stated that while driving and coming to a stop, the Engine Auto Start-Stop system failed to engage, and the engine revved significantly, causing the vehicle to move forward unintendedly.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52631 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 52631 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 52631 cover?
The manufacturer filed it against 1 model year: 2024 Ford Bronco. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
