Other engine problem on the 2006 BMW X3
1 crash 1 fire 2 injuries 4 of the 6 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.
Only 6 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 engine problem gets reported
There are 6 reports of other engine problem on the 2006 BMW X3, 6 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 95,000 miles. It is the 6th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 95,500 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, 1 a crash, 1 a fire and 2 an injury are 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 2006 has 6. 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.
Tl*the contact owns a 2006 bmw x3. While driving between 60-65 MPH, the contact began decelerating for traffic and the vehicle began shaking and then shut off. Approximately two minutes later, the vehicle would restart. The failure has occurred four times and has been to the dealer three times for the stalling. The dealer could not duplicate the failure. Most recently, the engine light began illuminating intermittently. The current mileage was 18,000 and failure mileage was 16,352.
The intake boot between the mass air sensor and the throttle body cracks over time. This causes the check engine light to come on. Even though this is a known failure item, and the car is within the cpo warranty period, bmw does not cover any hoses or tubes, as they believe they are "wear" items. Since it is not covered its a $175 dollar diagnostic fee and $38.54 for the part vs $50 deductible. You do not know if your repair is covered until the diagnostic, so short of having to take it to another mechanic to have it checked you could be penalized $125 for wanting you car repaired under the extended warranty which you paid extra for. *tr
My bmw x3 has had its engine mount bolts sheared off. There are no indications of the bottom of the vehicle having been hit by any objects. The vehicle's mileage is in the low 90,000 mile range. An internet search reveals that this is a common problem happening to many bmw x3's, at low mileage. They also claim that the broken motor mount bolts, could result in a serious accident. The bmw service manager, I talked to, indicated that he has seen this similar issues, but was not aware how wide spread the problem is. His guess of why this may be happening is due to different thermal expansion and contraction of the 3 different metals involved in the mounting system. The way I discovered the problem was that the engine oil drain plug was misaligned with a protective shroud. I have been occasionally noticing a thump coming from the engine compartment. I had my ball joints and front-end checked out about a year ago and everything checked out fine. I suspect now, that the thump sound is due to the sheared engine mount bolts. If that's indeed the case, I would have been driving the vechile with the engine mount bolts sheared off for about…

How far this goes
This page is kept out of search results because 6 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 6 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 engine problem happen on the 2006 BMW X3?
Across 6 owner reports that included an odometer reading, half were filed by 95,000 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 engine problem on the 2006 BMW X3?
6 reports have been filed with NHTSA, about 0.2 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.
