MINI filed this with NHTSA as a service bulletin dated Nov 1, 2022, received Jan 3, 2023, about the structure. It names 10 model years (2016–2022). 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.

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 10 model years this bulletin names have filed 141 complaints with NHTSA since 2015. 3 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.
I was approaching a red light on a road that is 35mph. As I was coming to a stop my passenger side window shattered out of nowhere. There were no people around outside the vehicle and as I mentioned I was going so slow, I can't imagine any rock kicked up would have done this. There was glass everywhere in my car.

Certain 2019 MINI and BMW models are equipped with older evaporators that are not lined correctly to prevent aluminum corrosion from the new R-1234yf refrigerant, causing premature leaks of the refrigerant into the cabin while driving.

Common questions
Source: NHTSA, 49 CFR 579.5Is MINI M540122 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 M540122 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 M540122 cover?
The manufacturer filed it against 10 model years: 2022 MINI Clubman, 2021 MINI Clubman, 2020 MINI Clubman, 2022 MINI Cooper, 2021 MINI Cooper, 2020 MINI Cooper and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
