Complete transmission failure on the 2006 MINI Cooper
Only 3 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 complete transmission failure gets reported
There are 3 reports of complete transmission failure on the 2006 MINI Cooper, 3 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 98,000 miles. It is the 13th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 53,000 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 $2,800–$8,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 5 model years of this car. It shows up earliest on the 2006, at a median of 55,000 miles, and latest on the 2005 at 75,000 miles.
By volume the 2003 carries the most reports, with 22; the 2006 has 3. 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.

2006 mini-cooper. Consumer writes in regards to transmission failure. *smd the dealer was unable to duplicate the failure, but they did state the transmission was in the process of failing. The consumer stated when he attempted to get on the freeway, the vehicle would not shift into 2nd gear. The manufacturer offered to pay 1/2 of the cost on the bill, which totaled $8,000. *jb
I heard a whirring sound and a light came on the dashboard. Took it to the mini cooper dealership bob smith where I had the car serviced and where it was originally purchased. The technician did not pull any codes, just took the car for a ride. He pronounced that the transmission had to be replaced as it is a sealed transmission as it is a "sealed" transmission and therefore it could not be repaired at a cost of $9000! He then took off $1500 for a cost of $7500! Googled this problem to find out that so many mini's had this problem that a class action lawsuit had been filed. Contacted miniusa who scoffed at the problem and offered no help or relief. Hoping that mini will be forced to deal with this issue and that a recall will be initiated before anyone is seriously injured. *tr
Our car has only 53,000 miles on it. We are informed by 2 different dealers that it needs a new transmission totaling $10,000. We were not aware of the class action suit for this very issue that settled late last year. Bmw/mini knew about the defective transmission and said nothing. Our car is not drivable now and is unsafe to operate. It is worthless essentially after being maintained per their guidelines. When driving it lost control and was not able to shift into gears. Was stuck in 4th gear one time and was hard to stop. Could have caused an accident but we were able to get control.

How far this goes
This page is kept out of search results because 3 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 3 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 complete transmission failure happen on the 2006 MINI Cooper?
Across 3 owner reports that included an odometer reading, half were filed by 55,000 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 complete transmission failure on the 2006 MINI Cooper?
3 reports have been filed with NHTSA, about 0.4 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.
