Loss of braking on the 2009 Toyota Corolla
11 crashes 6 injuries 17 of the 22 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 loss of braking gets reported
Owners of the 2009 Toyota Corolla report loss of braking at a median of 35,000 miles. A quarter of the reports come in before 20,000 miles and a quarter after 40,000 miles, from 18 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 12th most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 90,000 miles at the ninetieth, a spread of 81,559 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.
50% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 10,441 miles | 22,275 miles | 33,735 miles | 40,750 miles | 92,000 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, 11 a crash and 6 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 $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 14 model years of this car. It shows up earliest on the 2014, at a median of 1,000 miles, and latest on the 2002 at 140,000 miles.
By volume the 2010 carries the most reports, with 38; the 2009 has 22. 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

As an owner of 2009 corolla I'm very concerned about recall for brake failure in extremely low temperatures. Toyota has limited its recall and repair of this problem only to certain states. I live in nw indiana, less than 4 miles from illinois state line. Illinois owners will have their brakes fixed; indiana is not on the list. Toyota?s state restriction does not make any sense. Nw indiana has the same weather as chicago, il and the same extreme low temperatures. Additionally, I conduct a huge portion of my business and personal matters in the state of illinois. I will have to drive my car knowing that brakes can fail on me on any given day with the extreme low temperatures (and we have months of such days ahead). How is toyota allowed to discriminate between states without just cause? We all have a right to drive safe vehicles. What can be done to enforce toyota to correct this problem? *tr
My wife has experianced brake fade, brake failure and inconsistant braking with her 2009 corolla. I have noted that this seems to be related to temperature, humidity and warmup of the operating system. The situation was briefly improved after the previous recall for the brake boostedr problem but returned in 60 days. Toyota seems to not care about this issue
I am extremely upset because my brakes failed for a brief (but scary) time tonight on my way home from work. They also made a very strange noise. I have 24,000 miles on the car, almost all highway. Please call asap. *tr

How far this goes
Complaints are voluntary, so 22 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 2009 Toyota Corolla?
Across 18 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 20,000 miles and a quarter after 40,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is loss of braking on the 2009 Toyota Corolla?
22 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.
