BMW bulletin B662719
BMW filed this with NHTSA as a service bulletin dated Sep 1, 2022, received Aug 19, 2019, about the lane departure — 2 documents under this number. It names 42 model years (2016–2023). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B662719 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 B662719 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 B662719 cover?
The manufacturer filed it against 42 model years: 2017 BMW M, 2016 BMW M, 2022 BMW X3, 2021 BMW X3, 2020 BMW X3, 2019 BMW X3 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
