BMW filed this with NHTSA as a service bulletin dated Dec 20, 2023, received Dec 6, 2023, about the steering — 2 documents under this number. It names 4 model years (2023–2024). 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.

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. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported

Driving on the highway, unexpectedly i was not able to turn anymore. On the road was something I wanted to not hit, but steering did not work as usual. The car was forced to the left into the wall and the only thing i was able to do was using the breaks steady and slowly.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B320523 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 B320523 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. Every BMW warranty extension on file lists the ones BMW has filed.
Which vehicles does B320523 cover?
The manufacturer filed it against 4 model years: 2024 BMW 3 Series, 2023 BMW 3 Series, 2024 BMW X3, 2024 BMW X4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2024 BMW: built on or after 18 Aug 2023; G01 X3 Sports Activity Vehicle: built 18 Aug 2023 – 27 Sep 2023; G02 X4 Sports Activity Coupe: built 30 Aug 2023 – 13 Sep 2023 — the build date is on the certification label in the driver’s door jamb.
