BMW bulletin B512224
BMW filed this with NHTSA as a service bulletin dated Mar 18, 2026, received Jan 25, 2025, about the unknown or other — 3 documents under this number. It names 20 model years (2024–2025). 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.

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 B512224 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 B512224 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 B512224 cover?
The manufacturer filed it against 20 model years: 2025 BMW 3 Series, 2024 BMW 3 Series, 2025 BMW 5 Series, 2024 BMW 5 Series, 2025 BMW X1, 2024 BMW X1 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
