Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches MINI’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.

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 14 model years this bulletin names have filed 154 complaints with NHTSA since 2015. 29 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.

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.

The contact owns a 2024 Mini Cooper S. The contact stated that a brake pad failure message was illuminated on the vehicle. The vehicle was taken to the dealer, who diagnosed the brake fluid service issue. The brake fluid flush was completed, and a complimentary oil change was provided.

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 M110323 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 M110323 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 M110323 cover?
The manufacturer filed it against 16 model years: 2024 MINI Clubman, 2024 MINI Cooper, 2022 MINI Cooper, 2021 MINI Cooper, 2020 MINI Cooper, 2019 MINI Cooper and more. 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: F54 MINI Clubman: built 13 Feb 2023 – 23 Jun 2023; F55 MINI Hardtop 4 Door: built 7 Feb 2023 – 29 Jun 2023; F56 MINI Hardtop 2 Door: built 9 Feb 2023 – 29 Jun 2023 — the build date is on the certification label in the driver’s door jamb.
