Other brake problem on the 2015 Toyota Corolla
7 crashes 2 injuries 9 of the 10 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 brake problem gets reported
Owners of the 2015 Toyota Corolla report other brake problem at a median of 15,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 35,000 miles, from 9 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 1,000 miles at the tenth percentile to 45,000 miles at the ninetieth, a spread of 42,239 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.
78% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 961 miles | 6,500 miles | 12,900 miles | 34,000 miles | 43,200 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, 7 a crash and 2 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–$1,800 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 24 model years of this car. It shows up earliest on the 1998, at a median of 15 miles, and latest on the 2003 at 80,000 miles.
By volume the 2010 carries the most reports, with 119; the 2015 has 10. 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.
On december 24th 2014 I was driving my vehicle (2014 toyota corolla s) in (d) and was trying to slow down, because the driver in front of me brake. When I depressed my brake pedal the vehicle accelerated. I shifted into neutral and continued to brake and it eventually slowed me down. I shifted back into (d) and continued on my way, although shaken up. The road conditions were good, there was no rain or ice on the road that day. I checked my floor mats to see if they were sticking to the acceleration pedal when I got into the driveway, but I did not notice any such defect with the floor mats sticking to the pedal. A few weeks later driving to work on 01/20/2015 around the same speed on the same road conditions the vehicle gave me unwanted acceleration again while attempting to brake. I performed the same way I had previously, I entered into neutral and braked, except this time I came within inches of the vehicle forward of me. The next day on 01/21/2015 while driving to work the vehicle again performed the exact same malfunction as the previous day. On all days the road conditions were fine and should have not affected the vehicles…
Stopped at a red light with foot on the brakes. Out of nowhere the car accelerated forward extremely fast. Forced to hit an car in front of me within a car or two, distance wise. After the incident the RPM gauge fluctuates from low to high. In addition, once gas pedal is pressed car slows down and eco activates, then after about 5 seconds car accelerator extremely fast.
I purchased a 2015 toyota corolla from charles maund toyota on june 15, 2015 and around a month after I bought it, I have been having problems with the breaks ever since. My service technician and other service men said a lot of people had been bringing these cars (2015 toyota corolla) back for the same noise and other brake issues as I described. There is a cracking noise when I put my foot on the brakes sometimes. Dealer service men said this is something that I will always hear because of the materials toyota makes their brakes and pads out of, once it reaches a certain temperature, I will hear the noise. Sometimes brake pedal goes down to the floor by its self after I have stopped. Service men said they felt the brake pedal go down and said they fixed it. But on october 30, 2015 it started going down by its self again. Both front wheels now making loud popping or knocking noise when I put my foot on the brake sometimes and wheels do not stop, they keep turning. Service men said they could not do anything because it never happened when they drove the car. October 21, I had another scary event in the parking lot at my job as I…

How far this goes
Complaints are voluntary, so 10 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 brake problem happen on the 2015 Toyota Corolla?
Across 9 owner reports that included an odometer reading, half were filed by 15,000 miles. A quarter were filed before 5,000 miles and a quarter after 35,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other brake problem on the 2015 Toyota Corolla?
10 reports have been filed with NHTSA, about 0.1 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.
