Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (5 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 6 model years this bulletin names have filed 294 complaints with NHTSA since 2015. 4 of them name Structure — 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.
While driving under normal conditions with no external impact, debris, rock strike, or other identifiable cause, the panoramic moonroof shattered explosively (with a loud report resembling a gunshot). Glass fragments dispersed across the roof area, and portions of the panel collapsed inward into the interior mesh roof cover.

The Soft Close feature of the car continues to close even if there is a hand or finger in its way, I crushed by thumb while getting out of the car. I am concerned about the safety of the feature especially if there are young kids in the car, the injury could have been much more serious
2023 BMW X7 · Structure · filed with NHTSA Apr 10, 2023 · ODI 11516235
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 B410423 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 B410423 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 B410423 cover?
The manufacturer filed it against 6 model years: 2024 BMW X5, 2023 BMW X5, 2024 BMW X7, 2023 BMW X7, 2024 BMW XM, 2023 BMW XM. 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: 2023 – 2024 BMW: built 9 May 2023 – 30 May 2023; G05 X5 Sports Activity Vehicle: built 9 May 2023 – 30 May 2023; G07 X7 Sports Activity Vehicle: built 9 May 2023 – 29 May 2023 — the build date is on the certification label in the driver’s door jamb.
