Other powertrain problem on the 2004 Toyota 4RUNNER
1 injury 1 of the 9 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 powertrain problem gets reported
Owners of the 2004 Toyota 4RUNNER report other powertrain problem at a median of 80,000 miles. A quarter of the reports come in before 35,000 miles and a quarter after 100,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 17th most-reported problem on this model year.
The mileage distribution
The reported range runs from 20,000 miles at the tenth percentile to 145,000 miles at the ninetieth, a spread of 124,200 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 |
|---|---|---|---|---|
| 20,200 miles | 33,250 miles | 81,000 miles | 98,875 miles | 144,400 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 an injury 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–$4,500 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 17 model years of this car. It shows up earliest on the 2019, at a median of 500 miles, and latest on the 1999 at 190,000 miles.
By volume the 2006 carries the most reports, with 20; the 2004 has 9. 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.
1. There is a serious "clunk" noise when taking my foot off the brake from a stop. 2. My vehicle makes a loud noise when stopped at an intersection combined with a surging forward as if being rear ended. 3. When applying the brakes, after it has been sitting for a number of hours, it shakes and bangs extremely violently. *tr
I have a 2004 toy 4-runner, v-8 all wheel drive that I am generally satisfied with, but there is one issue that is frightening. When I come to an abrupt stop there is a forward lunge that feels like I have been hit from behind. The vehicle lunges forward the brakes do not always contain this forward motion. I have narrowly adverted hitting the car in front of me several times. This is obviously a safety issue that frankly scares the '!@#$% out of me. *tr
Four months ago I purchased a 2004 toyota 4runner limited with approx. 82,000 miles. A month or so later, I approached a stop sign and as I braked, the vehicle suddenly accelerated. I stepped as hard as I could on the brake and fortunately, the vehicle stopped. At the time, I was scared but thought that maybe by mistake, my foot was spanning both pedals (I didn't think so but couldn't be 100% positive). Yesterday, I approached another intersection with my foot clearly on the brake pedal as I was coming to a controlled stop when, suddenly, the vehicle accelerated aggressively. Again, I was able to slow the vehicle down by almost standing on the brake pedal, though not enough to stop me from going through the intersection without stopping. This time there was no doubt - the vehicle accelerated on its own. The pedal did not stick as my foot was on the brake as I was coasting to a stop. This vehicle definitely has a defect and it was very scary. My wife will not drive this car and I only will now if I absolutely have to. *tr

How far this goes
Complaints are voluntary, so 9 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 powertrain problem happen on the 2004 Toyota 4RUNNER?
Across 8 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before 35,000 miles and a quarter after 100,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other powertrain problem on the 2004 Toyota 4RUNNER?
9 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.
