Other brake problem on the 2017 Toyota 4RUNNER
Only 2 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 other brake problem gets reported
There are 2 reports of other brake problem on the 2017 Toyota 4RUNNER, 2 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 88,000 miles. It is the 9th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 11,000 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
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 22 model years of this car. It shows up earliest on the 2025, at a median of 5 miles, and latest on the 2002 at 175,000 miles.
By volume the 2004 carries the most reports, with 37; the 2017 has 0. 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.
When you apply the brakes with full force while driving; the brakes lock up for a short period of time on one side of the vehicle, causing the vehicle to swerve uncontrollably. This is extremely dangerous vehicle when the brakes are applied with hard force at speeds at around 35 MPH or higher. Luckily I am a very experienced driver and car handler and was able to react quick enough to control the vehicle one time when I had to apply the brakes hard at highway speeds when a car swerved in front of me suddenly. I have since done many tests on this vehicle myself and concluded that one wheel on the left side of the vehicle is locking up which is causing the vehicle to quickly and violently swerve. The test I did was to apply the brakes very hard and suddenly while driving on a flat grassy field at 35 MPH. The grass in the field had been cut a few days earlier and was at a height of about 4 inches and dry, the air temperature was 82 degrees f. After applying the brakes hard, I would stop the vehicle and go back and look at the path of the vehicle where the brakes were applied. There was clearly a patch of ground the same width as the…
Vehicle bought new 8/2017. Has approx. 7,000mles. This is the 3rd or 4th similar incident but the most severe. Driving on I-95, approx. 60 mpr, today, when I applied the brakes they seemed to lock and although my first thought was that the car also accelerated it may have been only my expectation of slowing down and that wasn't happening. The brake pedal only seemed to compress about 2-3". Luckily I was able to pull over and the car did stop. I continued on without incident but like I said this was the 3rd or 4th time and the most severe.

How far this goes
This page is kept out of search results because 2 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 2 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 2017 Toyota 4RUNNER?
Across 2 owner reports that included an odometer reading, half were filed by 10,000 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 other brake problem on the 2017 Toyota 4RUNNER?
2 reports have been filed with NHTSA, about 3.9 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.
