Other engine problem on the 2009 Ford Fusion
2 crashes 2 fires 3 injuries 7 of the 24 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 2009 Ford Fusion report other engine problem at a median of 105,000 miles. A quarter of the reports come in before 80,000 miles and a quarter after 140,000 miles, from 21 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 8th most-reported problem on this model year.
The mileage distribution
The reported range runs from 50,000 miles at the tenth percentile to 190,000 miles at the ninetieth, a spread of 137,000 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 51,000 miles | 81,540 miles | 102,653 miles | 140,000 miles | 188,000 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, 2 a crash, 2 a fire and 3 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 15 model years of this car. It shows up earliest on the 2012, at a median of 45,000 miles, and latest on the 2009 at 105,000 miles.
By volume the 2010 carries the most reports, with 645; the 2009 has 24. 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.
I was driving to the dealer to have them check a tapping sound coming from the engine that I had heard earlier that day. I made it about 5 miles from home, and the engine had blown, no warning lights, nothing other than the sound that had just occurred that morning. Now I had made it about 90k after the new engine was installed (now at 139000), and again the engine has blown. This time it was a little worse, the car had a sudden increase of power, and then all the sudden there was a loud bang, and a cloud of white smoke followed by smoke coming from the hood and the rear of the car. When I pulled onto the shoulder I looked under the car and saw a piece of the engine fall out and then all of the oil as well. I take very good care of every vehicle I own, the first time it happened the dealership told me it looked like I hadn't changed my oil ever. It was just a sludge. *tr
When driving at a normal speed, the idle of the car quickly drops and you are unable to maintain your speed. You immediately are forced to stop the car, turn it off and let it sit to reset it's self where ever on the road you are. This has happen randomly last few weeks. Just a few days ago it got increasingly worse. Was entering highway off an exit trying to merge. Was unable to get the speed because the idle dropped. Luckily had just enough time to get to shoulder to sit and wait. Had it been few seconds longer would of merged with highway traffic and then car would of came to a quick halt. The diagnosis to this problem the throttle body went bad. *tr
Slowed down to turn in a parking lot and car just stalled and check engine light and tool light came on. I had a diagnostic rsn and got code 2104 & 2112 meaning throttle body failure. *tr

How far this goes
Complaints are voluntary, so 24 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.
