Other powertrain problem on the 2009 MINI Cooper S
Only 5 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When other powertrain problem gets reported
There are 5 reports of other powertrain problem on the 2009 MINI Cooper S, 5 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 92,000 miles. It is the 7th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 29,800 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $400–$4,500 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 6 model years of this car. It shows up earliest on the 2003, at a median of 5,000 miles, and latest on the 2006 at 80,000 miles.
By volume the 2006 carries the most reports, with 14; the 2009 has 5. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
The timing tensioner on my mini cooper s backed out, resulting in a massive oil loss while at highway speeds. This is apparently a known issue by mini, but no known recall has been issued at this point. *tr
Tl* the contact owns a 2009 mini cooper s. The contact stated that while driving 20 MPH, the clutch slipped as the rpms increased to 6000. The contact did not take the vehicle to the dealer for inspection or repairs. The manufacturer was notified of the failure. The failure mileage was 45,000.
I was driving my mini cooper on I-95 when the I noticed a very strong burning smell and the clutch was giving me difficulty changing gears. As I was getting off I-95 the gears were not responding and the car began to slow down. I got off I-95 and just made it to a main blvd. When the clutch gave out and the car would not move. I could see the cars in the rear view mirror coming at full speed and honking at me to move out of the of the way. I called 911 and asked for a patrol to spot traffic and then tried to get out of the car to ask for help but almost got ran over by cars passing by. I thought I was going to get either hit or killed. Two man in a van stopped and pushed my car out of the way until the truck stopped. The police car never showed up. A west palm braman mini cooper service man was driving by and told me the clutch was completely burnt out and to tow the car to his facility. I did and mini cooper refused to fix it even though they are aware of the defect and the many complaints. They tried to tell me the clutch was worn out but the car only has 13,000 miles, they also tried to blame it on aggressive driving or that I…

How far this goes
This page is kept out of search results because 5 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 5 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other powertrain problem happen on the 2009 MINI Cooper S?
Across 5 owner reports that included an odometer reading, half were filed by 30,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other powertrain problem on the 2009 MINI Cooper S?
5 reports have been filed with NHTSA, about 1.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
