Other engine problem on the 2005 Toyota Highlander

1 fire 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.

Only 6 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 engine problem gets reported

There are 9 reports of other engine problem on the 2005 Toyota Highlander, 6 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 95,000 miles. It is the 14th most-reported problem on this model year.

The whole distribution

Percentiles of the 6 odometer readings owners gave.
10th25thMedian 75th90th
— — 27,500 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 fire 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 $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 2005 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.

Intermittent problem: while traveling approx 30 MPH (or cruising speed), attempted to pass another vehicle. The accelerator was pressed to the floor and the vehicle refused to accelerate for a period of approximately 2 seconds. Acceleration resumed after this period. Contacted toyota. Toyota said this is a normal phenomenon in their drive-by-wire systems.

1,905 miles NHTSA complaint 534541 filed 2005-05-10

2005 toyota highlander, car will accelerate from a dead stop on its own. Change transmission from park to drive and let off brake and car will accelerate without touching gas pedal fast enough to change gears and continue. Have reached a speed of 30 MPH before braking. The tachometer does not show that the engine is revving higher than a normal idle when in park changing into drive so it seems like an electronic problem, etc. Issue is intermittent. The car has been to 2 dealers over the time it has been owned and we were told the issue could not be duplicated so nothing could be done. I called the same day this email was sent and was told the same thing by the local toyota dealership. Well, the recalled gas pedals don't stick all the time so they are intermittent problems so where is the difference between their cars and ours! I have tried every contact number for toyota and cannot get anywhere!!!!!! *tr

30,000 miles NHTSA complaint 758983 filed 2010-02-05

My wife was driving our 2005 toyota within the city limits at a low rate of speed and noticed smoke coming out of the front engine hood area. There were no trouble lights showing for the engine at the time, nor was the temperature gauge showing a high temperature. She pulled over and found the grill area and front engine hood were melting and scortched. She called police / fire to respond to the scene. The fire department was unable to open the front hood, since it appeared that the release cable had melted from the extreme heat. They bent the hood up to gain access to the fire, and then extinguished the fire. Vehicle was towed to a local repair facility. *tr

How far this goes

This page is kept out of search results because 9 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 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 engine problem happen on the 2005 Toyota Highlander?

Across 6 owner reports that included an odometer reading, half were filed by 30,000 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 engine problem on the 2005 Toyota Highlander?

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.
