BMW bulletin B610926
BMW filed this with NHTSA as a service bulletin dated May 4, 2026, received May 18, 2026, about the electrical system. It names 2 model years (2025). 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationAn error in the Battery Management Electronics (SME) can lead to an interruption in communication, which can lead to the high-voltage system being turned off. The error is indicated by a Check Control message, and it is generally possible to continue driving until the vehicle is parked.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5; the full text comes from the manufacturer or a dealer. 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. Quote it at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B610926 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 B610926 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 B610926 cover?
The manufacturer filed it against 2 model years: 2025 BMW X5, 2025 BMW XM. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
