BMW bulletin B512724
BMW filed this with NHTSA as a service bulletin dated Nov 4, 2024, received Nov 25, 2024, about the electrical system. It names 10 model years (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 B512724 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 B512724 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 B512724 cover?
The manufacturer filed it against 10 model years: 2024 BMW 3 Series, 2024 BMW 4 Series, 2024 BMW 5 Series, 2024 BMW 7 Series, 2024 BMW 8 Series, 2024 BMW X3 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
