Other engine problem on the 2014 Subaru Impreza
2 crashes 2 of the 11 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 2014 Subaru Impreza report other engine problem at a median of 45,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 50,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 50,000 miles at the ninetieth, a spread of 48,243 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
38% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 3,557 miles | 23,725 miles | 46,250 miles | 50,000 miles | 51,800 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
Of these reports, 2 a crash 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 16 model years of this car. It shows up earliest on the 2017, at a median of 10,000 miles, and latest on the 2007 at 110,000 miles.
By volume the 2013 carries the most reports, with 50; the 2014 has 11. 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 2014 subaru impreza. The contact stated while driving approximately 70 MPH, the engine suddenly stalled. The vehicle restarted immediately and resumed in normal operation. The vehicle had not been diagnosed or repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 424. The VIN was unavailable.
About 6-8 months ago as I was making a turn I pressed the brake pedal and instead of slowing down the engine throttled up. And after a few moments went back to normal. Two weeks ago as I pressed the brake pedal while coming to a stop sign the engine throttled up and I had difficulty coming to a stop. I put the car in park and turned it off. When I started it again the engine immediately went to high throttle to the point that the front of the car started vibrating. I turned it off again and restarted it and this time it was ok. I took the car into the subaru dealership. Their mechanic ran the diagnostics and was unable to pin point the problem. They decided to call the subaru technical department and were told to not let me drive the car until their engineer took a look at the problem. This was a week ago and I have not been able to find out what they have found.
I experienced sudden extreme acceleration just after I pulled into my driveway. The car suddenly--very rapidly--accelerated and crashed through wooden garage door and into the poured concrete wall at back of garage, cracking the wall and of course totaling the car.

How far this goes
Complaints are voluntary, so 11 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.

How common is other engine problem on the 2014 Subaru Impreza?

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.
