Ford filed this with NHTSA as a service bulletin dated Jun 28, 2024, received Jul 3, 2024, about the electrical system. It names 1 model year (2025).

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

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2025 Explorer XLT/Police Interceptor Utility vehicles may exhibit diagnostic trouble code (DTCs) B1A01:01, B1A02:01, B1A03:01, B1A04:01, B1A05:01 and/or B1A06:01 in the audio control module (ACM). This may be due a software concern within the ACM. If any of these DTCs are identified but the vehicle does not present any radio functionality concerns, replacement or reprogramming of the ACM will not resolve this condition at this time. Engineering is currently working on a solution and a software update is expected in Q3 2024

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 109 complaints with NHTSA since 2015. 23 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.
Gateway module does not work. I've had my 2025 vehicle since 11/21/2024 (over 7 months) and it has never worked. I have not had a safety update since 05/2024 when it was at the factory. There has been many OTA updates and updates that need to be preformed at dealership and have not had any completed.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52677 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 52677 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 52677 cover?
The manufacturer filed it against 1 model year: 2025 Ford Explorer. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
