MINI filed this with NHTSA as a service bulletin dated Apr 30, 2025, received May 2, 2025, about the electrical system. It names 1 model year (2025).

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 1 model year this bulletin names have filed 6 complaints with NHTSA since 2015. 1 of them name Electrical System — 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 lowering the convertible top on my Mini Cooper Convertible, the trunk partition was not fully in place. Normally, the vehicle will prevent the roof from operating or provide a notification if the partition is not correctly positioned. In this case, the safety interlock system failed to warn me or stop the roof from lowering.

Common questions
Source: NHTSA, 49 CFR 579.5Is MINI M540124 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 M540124 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 M540124 cover?
The manufacturer filed it against 1 model year: 2025 MINI Cooper. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
