Read by machine from the document NHTSA serves (9 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.
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 11 complaints with NHTSA since 2015. 3 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.
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.

Common questions
Source: NHTSA, 49 CFR 579.5Is MINI 6412900100 a recall?
No. A warranty extension 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 6412900100 repair free?
A warranty extension is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 6412900100 cover?
The manufacturer filed it against 1 model year: 2018 MINI Countryman. 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: built 9 Mar 2017 – 26 Feb 2018 — the build date is on the certification label in the driver’s door jamb.
