Loss of braking on the 2002 Subaru Impreza
1 crash 1 of the 7 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 3 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 loss of braking gets reported
There are 7 reports of loss of braking on the 2002 Subaru Impreza, 3 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 78,000 miles. It is the 9th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 26,000 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, 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 $400–$3,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 3 model years of this car. It shows up earliest on the 2013, at a median of 15,000 miles, and latest on the 2002 at 25,000 miles.
By volume the 2013 carries the most reports, with 8; the 2002 has 7. 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.
Approaching a toll-booth I began braking moderately from roughly 45mph. At about 15mph I went over some broken pavement with small pock marks. The pedal immediately went to the floor, or thereabouts, and a significant loss of braking power occurred. Upon releasing the brake and reengaging the vehicle's brakes, the brakes operately properly and stopped the car. By the time I stopped, however, I was already 20 feet beyond the tollbooth. Thank god there was not a car in front of me. I have also been able to repeat this scenario numerous times over rough, dry pavement with light to moderate braking. The bumps seem to confuse the ABS.(?) I brought the car into marin subaru, who confirmed a brake hydraulic failure and replace the offending parts.*ak
Consumer applied the brake and the pedal went to the floor. The vehicle went through the intersection before consumer could apply the brake again to stop. The road was dry and even when this occurred. *ph *nlm
I have an 02 subaru impreza wrx. The ABS system activates prematurely and overly-agressively in a variety of conditions. Most often it happens when attempting to stop and driving over bumpy roads. Something as minor as a 1/2 inch dip in the pavement can set off the ABS. Once the system activates the pedal goes to the floor and there is momentarily a complete loss of braking ability. It can extend the braking distance by 1 or 2 full car lengths as compared to without ABS and has caused me to nearly crash into other cars several times.*ak

How far this goes
This page is kept out of search results because 7 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 7 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 loss of braking happen on the 2002 Subaru Impreza?
Across 3 owner reports that included an odometer reading, half were filed by 25,000 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 loss of braking on the 2002 Subaru Impreza?
7 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.
