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 7 model years this bulletin names have filed 76 complaints with NHTSA since 2015. 14 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.
I am unknown of what system has failed but the issue is that while the car is in motion, it will completely shut off. All Electrical will disengage and there have been times where a pop up has come on my screen stating that air bags and seat belts are non functioning to get to a service station as soon as possible.

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 BMW B654123 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 B654123 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. Every BMW warranty extension on file lists the ones BMW has filed.
Which vehicles does B654123 cover?
The manufacturer filed it against 7 model years: 2023 BMW 5 Series, 2024 BMW 7 Series, 2023 BMW 7 Series, 2022 BMW 7 Series, 2024 BMW XM, 2023 BMW XM and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
