MINI filed this with NHTSA as a service bulletin dated May 1, 2022, received Jul 5, 2022, about the engine. It names 11 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 11 model years this bulletin names have filed 172 complaints with NHTSA since 2015. 30 of them name Engine — 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.
The contact owns a 2017 Mini Cooper S. The contact stated while driving at an undisclosed speed, the engine was vibrating abnormally. There was no warning light illuminated. The vehicle was taken to the dealer, who determined that the passenger’s side engine mount needed to be replaced. The vehicle was not repaired.
2017 MINI Cooper · Engine · filed with NHTSA Mar 9, 2026 · ODI 11723036
My engine malfunctioned after the module under the back seat was wet from an unknown water leak in the vehicle. My vehicle lost power without warning until I came to a complete stop on the side of a very busy highway. I'm not sure if the repair center kept the faulty module or not I would have to check.

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 MINI SIM640122 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 SIM640122 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 SIM640122 cover?
The manufacturer filed it against 11 model years: 2017 MINI Clubman, 2022 MINI Cooper, 2021 MINI Cooper, 2020 MINI Cooper, 2019 MINI Cooper, 2018 MINI Cooper and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
