What it saysA loud “click”- type noise can be heard from the rear axle brakes when driving off forwards, and/or in reverse. NHTSA’s full summary ↓
BMW filed this with NHTSA as a service bulletin dated Jun 11, 2025, received Jun 17, 2025, about the service brakes. It names 5 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 (4 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
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 16 complaints with NHTSA since 2015. 7 of them name Service Brakes — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
After returning to my vehicle, I received an alert that the chassis stabilization system had a fault. The car was free, rolling and had no parking brake while it was on an incline. There was zero ability to turn the steering wheel. I consider this a life-threatening safety issue

I was driving a brand-new 2025 BMW i5 electric car, just leased from dealer the day before. The car was at rest, waiting for traffic light to turn green. Then the car started to move forward, and suddenly hit the car in front with a big thrust.

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 B340725 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 B340725 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 B340725 cover?
The manufacturer filed it against 5 model years: 2025 BMW 5 Series, 2025 BMW 7 Series, 2023 BMW XM, 2025 BMW i5, 2025 BMW i7. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
