Other engine problem on the 2010 Toyota Highlander
1 crash 2 fires 3 of the 11 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 engine problem gets reported
Owners of the 2010 Toyota Highlander report other engine problem at a median of 80,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 110,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 6th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 130,000 miles at the ninetieth, a spread of 124,267 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 |
|---|---|---|---|---|
| 6,850 miles | 25,375 miles | 80,202 miles | 109,500 miles | 131,117 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 a crash and 2 a fire 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–$4,000 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.
The same failure on other years
The same failure is reported on 22 model years of this car. It shows up earliest on the 2013, at a median of 2,300 miles, and latest on the 2011 at 120,000 miles.
By volume the 2008 carries the most reports, with 46; the 2010 has 11. 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.

While driving on the interstate at 70 MPH, a deer hit my car. Airbags did not deploy, damaged front end, minor damage to the bumper, major damage to engine compartment and windshield was cracked why did the airbag not deploy our major concern concern that will the airbag work after repairs?? *tr
Twice in september 2014, as I was approaching a stop light, I pressed the brakes and slowed to nearly a stop. The engine suddenly accelerated very high, and if I had not already had a foot on the brakes, I would have gone into an intersection. The engine was running so high that it was difficult to keep it from moving. I shifted into neutral, came to a complete stop, and while the transmission was in neutral, took my foot off the brake pedal. The engine immediately returned to normal idle. This same sequence happened both times. This has happened twice this month, but these are the first occurrences since I purchased the vehicle new. I called the toyota dealer, and the service person said that if the vehicle isn't demonstrating that behavior when I bring it in, they would not be able to find what caused it. They indicated that the vehicle data recorder would not record such an event. They said they would add a note about this to the record they have on this vehicle (they have done all the service since I purchased it from them). I have already decided that should it happen again, I will trade the vehicle. I don't like having to…

How far this goes
Complaints are voluntary, so 11 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 engine problem happen on the 2010 Toyota Highlander?
Across 8 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before 25,000 miles and a quarter after 110,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other engine problem on the 2010 Toyota Highlander?
11 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.
