Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B661719 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 B661719 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 B661719 cover?
The manufacturer filed it against 9 model years: 2021 BMW X3, 2020 BMW X3, 2019 BMW X3, 2018 BMW X3, 2017 BMW X3, 2021 BMW X4 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
