BMW bulletin B652725
BMW filed this with NHTSA as a service bulletin dated Feb 11, 2026, received Dec 1, 2025, about the electrical system — 3 documents under this number. It names 24 model years (2025–2026). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B652725 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 B652725 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 B652725 cover?
The manufacturer filed it against 24 model years: 2026 BMW 2 Series, 2025 BMW 2 Series, 2026 BMW 3 Series, 2026 BMW 4 Series, 2025 BMW 4 Series, 2026 BMW 5 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
