Other engine problem on the 2015 BMW X3
3 fires 3 of the 25 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other engine problem gets reported
Owners of the 2015 BMW X3 report other engine problem at a median of 75,000 miles. A quarter of the reports come in before 40,000 miles and a quarter after 85,000 miles, from 13 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 20,000 miles at the tenth percentile to 115,000 miles at the ninetieth, a spread of 92,920 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
23% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 21,080 miles | 40,000 miles | 76,000 miles | 85,000 miles | 114,000 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
Of these reports, 3 a fire is mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $300–$4,000 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.
The same failure on other years
The same failure is reported on 17 model years of this car. It shows up earliest on the 2020, at a median of 10,000 miles, and latest on the 2022 at 150,000 miles.
By volume the 2013 carries the most reports, with 53; the 2015 has 25. 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.
There were a total of 4 incidences. 2/21/15 took bmw x3 xdrive28i to dealer with 112 miles on car, after car engine revved higher as I was coming down a hill to a complete stop. I had to practically stand on the brake for car to stop. Acceleration lasted about 4 seconds after stopping. Had to keep my foot on brake during that time. It happened a second time on the way to dealer; going up a slight hill, while coming to a complete stop. Prior to the above date, on 2/16/15, car also accelerated by itself while driving about 55 MPH on the highway. I had to step on break to slow down. Later that day the car accelerated by itself while rolling in a parking lot. I had to break hard to stop it. On 2/21/15 the dealer requested bmw na to send their engineers to check out the car. 2/24/15 bmw na advised me that "the car only does what you tell it to do with one of the controls.the engineers will be going to the dealership to check if anything is wrong with" my 2015 x3 xdrive. I advised them "they were looking for the wrong thing since there is something wrong with a car that accelerates when you are stepping on the break." they "should be…
When rainy day , my car sometimes came out smoke on a city street. I took into different bmw dearler, but they claim that is the design of the car, because the aviator too close when raining it will came out smoke. I recorded and show to the service advisor and he show it to the mechanic and he told me that is what the mechanic told him.
I would like to file a complaint about bmw of north america missing recalls on my vehicle in 2015. I was not aware the recall and informed about the camshaft timing adjustment vanos engine stall issue. The issue is about the bolts that secure the housing for the variable camshaft timing adjustment (vanos) unit loosen over time and may possibly break which reduces the power of engine or stall. I own a 2012 bmx x3 2.8i (VIN: 5uxwx5c58clxxxxxx), starting last year, my check engine light has been on and off from time to time. I did not understand this defective vanos design was the reason until last month I checked my vehicle in for engine problems with RPM automotive, they ran a full diagnostics and confirmed with error codes 130c01,130108 and 131508 which indicates vano and camshaft position sensors for my n52t 6-cylinder engine. I contacted bmw dealer at orange park, fl, they ignored my request and told me my vehicle is not on the recall list. I have done the research and confirmed my vehicle x3 xdrive 28i is on the recall list. Please see the recall at…

How far this goes
Complaints are voluntary, so 25 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.

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.
