BMW filed this with NHTSA as a service bulletin dated Oct 27, 2023, received Nov 1, 2023, about the electrical system. It names 5 model years (2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. 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 4 model years this bulletin names have filed 117 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.
I brought a brand new BMW IX fully electric vehicle in May, 2023. A couple of weeks ago in early September, the “Emergency Call System Malfunction” warning light came on, and I can also smell a chemical burn from the vehicle. I dropped it off to Eastbay BMW in Pleasanton, California. 4350 Rosewood Drive, Pleasanton, California 94588.
2023 BMW iX · Electrical System · filed with NHTSA Sep 28, 2023 · ODI 11547159
Our vehicle dies while driving down the highway, twice now in less than 30 days. I drivetrain and low-power warning came on, but the car died and wouldn't start. The obvious risk is that we were driving on the highway and barely avoided being in an accident as I tried to steer us off the road. The second time we were at a park.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B653123 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 B653123 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 B653123 cover?
The manufacturer filed it against 5 model years: 2023 BMW X5, 2023 BMW X6, 2023 BMW X7, 2023 BMW iX, 2023 BMW Redundant 7. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: F95 X5 M Sports Activity Vehicle: built Mar 2023 – Aug 2023; F96 X6 M Sports Activity Coupe: built Mar 2023 – Aug 2023; G05 X5 Sports Activity Vehicle: built Mar 2023 – Aug 2023 — the build date is on the certification label in the driver’s door jamb.
