What it saysNoises from the front axle when driving over rough road surfaces, or when turning. NHTSA’s full summary ↓
BMW filed this with NHTSA as a service bulletin dated May 22, 2026, received Jun 1, 2026, about the suspension. It names 6 model years (2023–2025). 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.

Read by machine from the document NHTSA serves (3 pages), read Sep 30, 2026. A part number is shown only where it matches BMW’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B310626 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 B310626 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 B310626 cover?
The manufacturer filed it against 6 model years: 2025 BMW 5 Series, 2024 BMW 5 Series, 2023 BMW 5 Series, 2025 BMW 7 Series, 2024 BMW 7 Series, 2023 BMW 7 Series. 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: G60 5 Series Sedan: built 30 Jun 2023 – 30 Apr 2025; G70 7 Series Sedan: built 30 Jun 2022 – 30 Apr 2025 — the build date is on the certification label in the driver’s door jamb.
