BMW bulletin B661323
BMW filed this with NHTSA as a service bulletin dated Jan 5, 2026, received Oct 1, 2023, about the forward collision avoidance — 3 documents under this number. It names 6 model years (2022–2024). 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 B661323 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 B661323 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 B661323 cover?
The manufacturer filed it against 6 model years: 2024 BMW X3, 2023 BMW X3, 2022 BMW X3, 2024 BMW X4, 2023 BMW X4, 2022 BMW X4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
