2017 MINI Cooper S: what breaks, and at what mileage
What breaks on the 2017 MINI Cooper S
On the 2017 MINI Cooper S, the failure owners report most often is cruise control failure, with 3 reports on file. Across every failure mode on this year, half the dated reports were filed before 15,000 miles.
The failures owners actually file about
Owners have reported 6 named failure modes on the 2017 MINI Cooper S, and the three most-reported carry 63% of everything filed, so the trouble here is concentrated rather than scattered.
Cruise control failure leads with 3 reports and about 0.7 per 1,000 vehicles.
Wiring harness or short circuit follows with 1 report, median 80,000 miles.
Airbag failed to deploy in a crash follows with 1 report, median 15,000 miles.
By system, the reports fall mostly into adas (4), electrical (1) and airbag (1).
When these failures get reported
Too few of the reports on this year carry an odometer reading to describe the timing: 4 of them do. The mileages quoted elsewhere on this page come from the modes that have enough of them.

How bad it is when it goes
Across the named modes, 1 mentions a crash and 1 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 6.00, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: cruise control failure at $200–$1,400, wiring harness or short circuit at $400–$3,500, airbag failed to deploy in a crash at $1,000–$5,000 and tail light, brake light or signal failure at $100–$900. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
13% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.
Every reported failure mode
| Failure mode | System | Reports | With reading | 25th | Median | 75th | Per 1,000 | Typical repair | Severity |
|---|---|---|---|---|---|---|---|---|---|
| Cruise control failure | adas | 3 | 0 | — | — | — | 0.7 | $200–$1,400 | High |
| Wiring harness or short circuit | electrical | 1 | 1 | — | 81k | — | 0.2 | $400–$3,500 | High |
| Airbag failed to deploy in a crash | airbag | 1 | 1 | — | 17k | — | 0.2 | $1,000–$5,000 | Critical |
| Tail light, brake light or signal failure | lighting | 1 | 0 | — | — | — | 0.2 | $100–$900 | Moderate |
| Other engine problem | engine | 1 | 1 | — | 15k | — | 0.2 | $300–$4,000 | High |
| Other speed control problem | adas | 1 | 1 | — | 15k | — | 0.2 | $250–$2,000 | Critical |
Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2017 MINI Cooper S draws about 1.9 per 1,000 vehicles, which puts it in the 77th percentile of complaint rates among 2017 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 4,220 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2017 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Airbag failed to deploy in a crash
I was hit head on last night and air bags did not deploy. I had slowed to approx 10 MPH while vehicle that hit me was traveling approx 20-30mph. Vehicle the hit me was a mid 200's trail blazer. *bf *tr
Recalls on the 2017 model year
NHTSA has issued 3 recall campaigns covering the 2017 MINI Cooper S, affecting an estimated 6,335 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover exterior lighting:brake lights, air bags and seat belts:front:retractor. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
Recalls also distort complaint counts. Publicity about a campaign reminds owners that complaining is possible, so reports for a recalled component often spike after the recall rather than before it.
EXTERIOR LIGHTING:BRAKE LIGHTS
16,883 vehicles 2017-03-31- Defect
- BMW of North America, LLC (BMW) is recalling certain 2016-2017 MINI Cooper Clubman, Cooper S Clubman and JCW Clubman vehicles. When the affected vehicles are braking and the turn signals are on, the inner, bumper-mounted, brake light will go out. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
- Consequence
- If the brake light does not illuminate when a turn signal is activated, other drivers may be confused, increasing the risk of a crash.
- Remedy
- MINI will notify owners, and dealers will reprogram the vehicle to correct the brake lighting, free of charge. The recall began May 22, 2017. Owners may contact MINI customer service at 1-866-825-1525.
AIR BAGS
3,506 vehicles 2016-12-20- Defect
- BMW of North America, LLC (BMW) is recalling certain model year 2017 BMW 640i, 640i xDrive, 650i, 650i xDrive, M6, 535i, 535i xDrive, 430i, 430i xDrive, 440i, 440i xDrive, M4, X1 sDrive28i, X1 xDrive28i, i3, i8, Rolls-Royce Dawn, Mini Clubman Cooper, Clubman Cooper S, Cooper All4, Cooper S All4, Mini 4-Door Cooper, Cooper S, Mini 2-Door Cooper, Cooper S, John Cooper Works and 2016 BMW 528i, 528i xDrive, 535i, 535i xDrive, 550i, 550i xDrive, M5 and 535d vehicles. The affected vehicles have seat- mounted side air bag inflator initiators that may fail to ignite during a crash.
- Consequence
- If the air bag inflator initiator fails to ignite, the seat-mounted air bag will not deploy, increasing the risk of injury.
- Remedy
- BMW will notify owners, and dealers will replace the air bag modules, free of charge. The recall began February 6, 2017. Owners may contact BMW customer service at 1-800-525-7417.
SEAT BELTS:FRONT:RETRACTOR
15,455 vehicles 2016-10-17- Defect
- BMW of North America, LLC (BMW) is recalling certain model year 2016-2017 X1 sDrive28i, X1 xDrive28i, MINI Hardtop 4 Door Cooper, Mini Hardtop 4 Door Cooper S, MINI Cooper Clubman, and Cooper S Clubman, 2017 Rolls-Royce Ghost, and 2016 528i vehicles. The vehicle-sensitive locking mechanism of the seat belt Emergency Locking Retractor (ELR) for the driver's seat may not lock as designed. As such, these vehicles fail to comply with the requirements of the Federal Motor Vehicle Safety Standard (FMVSS) number 209, "Seat Belt Assemblies."
- Consequence
- In the event of a crash where heavy braking is applied, the Emergency Locking Retractor (ELR) may activate when the occupant is more forward in the seat, possibly increasing the risk of injury.
- Remedy
- BMW will notify owners, and dealers will replace the driver's seat belt assembly, free of charge. The recall began July 3, 2019. Owners may contact BMW customer service at 1-800-525-7417.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
Better and worse years of the same car
Across the 14 model years of this car that carry enough reports to score, 2002 comes out best at 65 and 2007 worst at 78.
Within the 2014–2017 generation specifically, 2015 is the strongest year at 68 and 2014 the weakest at 71.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2014-2017 generation, 2015 MINI Cooper S scores best at 68 and 2014 MINI Cooper S worst at 71.
The limits of complaint data
8 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 8 reports, 4 carried an odometer reading, so the mileages here describe 50% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 2017 MINI Cooper S?
The most-reported failures are cruise control failure (3 reports), wiring harness or short circuit (1 report, median 80,000 miles) and airbag failed to deploy in a crash (1 report, median 15,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Which year of the MINI Cooper S is best?
Within the 2014–2017 generation, 2015 scores best at 68 out of 100 and 2014 worst at 71. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
