What owners reported
Source: NHTSA complaint databaseOwners of the 10 model years this bulletin names have filed 156 complaints with NHTSA since 2015. 30 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.
I was pulling into shopping center all dashboard light up warnings etc. started to head home because of prior incident with computer failure. Car stopped mid intersection and went dead. Put it in park restarted and drove home. Headlights and electrical engine would not shut off. Called service to tow to dealership repair.

Common questions
Source: NHTSA, 49 CFR 579.5Is MINI M840818 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 M840818 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 M840818 cover?
The manufacturer filed it against 10 model years: 2017 MINI Clubman, 2020 MINI Cooper, 2019 MINI Cooper, 2018 MINI Cooper, 2017 MINI Cooper, 2016 MINI Cooper and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
