Other engine problem on the 2008 Subaru Impreza
1 crash 1 of the 14 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 2008 Subaru Impreza report other engine problem at a median of 60,000 miles. A quarter of the reports come in before 15,000 miles and a quarter after 60,000 miles, from 13 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 6th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 74,480 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
38% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 5,320 miles | 15,000 miles | 58,000 miles | 62,000 miles | 79,800 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, 1 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 2008 has 14. 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 2008 subaru impreza. While driving between 5-10 MPH and depressing the brake pedal, the engine revved up to 2,500 RPM's. The failure occurred soon after the vehicle was purchased. The vehicle has been taken to the dealer three times for this failure. It has since improved, but the engine still revs from 1,500 to 2,000 RPM's. The contact is concerned that the failure will worsen in the winter. She filed case number [xxx] with subaru. The current mileage was 1,107 and failure mileage was 400. Updated 07/17/08 information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
I own a 2008 subaru impreza sti which I purchased in feb. Of 08'. 2 months ago the car went into limp mode when I was driving home. I took it to the dealership to have it checked and they said it only had 1 1/2 quarts of oil in it. I had checked the oil the previous week and it had shown full. They requested that I give them record of my previous oil change so I did. Unfortunately, it did not have mileage documented because it was a small shop that did it for me. They refused my claim on the grounds that I did not maintain the car. They then sent me a re-call form in which it stated that the ecu was causing the car to run dangerously lean and was causing ring failures. I told my lawyer about this and sent him a copy of the letter. When he called the dealership, they told him that they were unable to make any repairs necessary and that it was my issue. *tr

How far this goes
Complaints are voluntary, so 14 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 2008 Subaru Impreza?
Across 13 owner reports that included an odometer reading, half were filed by 60,000 miles. A quarter were filed before 15,000 miles and a quarter after 60,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other engine problem on the 2008 Subaru Impreza?
14 reports have been filed with NHTSA, about 0.3 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.
