Other speed control problem on the 2004 Toyota Highlander
16 crashes 7 injuries 1 death 24 of the 35 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 speed control problem gets reported
Owners of the 2004 Toyota Highlander report other speed control problem at a median of 35,000 miles. A quarter of the reports come in before 15,000 miles and a quarter after 85,000 miles, from 29 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 1,000 miles at the tenth percentile to 115,000 miles at the ninetieth, a spread of 113,610 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.
48% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 1,000 miles | 15,000 miles | 36,000 miles | 86,000 miles | 114,610 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, 16 a crash, 7 an injury and 1 a fatality 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 $250–$2,000 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 21 model years of this car. It shows up earliest on the 2010, at a median of 5,000 miles, and latest on the 2003 at 80,000 miles.
By volume the 2004 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
I purchased a new 2004 toyota highlander on 3/26/2004 and after about 2 months started noticing a problem with hesitation when accelerating from a stop or when passing. The car feels like it dies for 1 to 2 seconds and then lurches forward. This is very dangerous when making a left hand turn at a light with oncoming cars from the opposite direction. This also causes problems when trying to merge with highway traffic or when passing. This occures every day and when it was reported to toyota service they stated it was a known issue with no fix or technical bulletin. *ak
Dt: 2004 toyota highlander with hesitation problem. For example, when entering interstate and need to accelerate, it hesitates then quickly jolts. Taken to dealer who said there is nothing they can do. Explained vehicle has an electric throttle control and is not controlled by a throttle cable as part of federal emissions regulation, this makes changing gears a little longer to do since the throttle does not open all the way out . *tt
Dt: the contact stated there was a problem with sudden acceleration. While shifting into reverse the vehicle suddenly accelerated on july 8, 2005. The problem did not reappear until november 22, 2005. The vehicle accelerated under the same conditions. He was able to stop the vehicle after it had gone through two fences and crashed into the corner of the neighbor's garage. The vehicle is currently at the dealership for diagnostics.*ak updated 12/27/05. *jb

How far this goes
Complaints are voluntary, so 35 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 speed control problem happen on the 2004 Toyota Highlander?
Across 29 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 15,000 miles and a quarter after 85,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other speed control problem on the 2004 Toyota Highlander?
35 reports have been filed with NHTSA, about 0.4 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.
