Misfire or rough idle on the 2005 Honda Pilot
Only 4 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 misfire or rough idle gets reported
There are 4 reports of misfire or rough idle on the 2005 Honda Pilot, 4 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 92,000 miles. It is the 30th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 73,000 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 $250–$1,600 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 15 model years of this car. It shows up earliest on the 2012, at a median of 100 miles, and latest on the 2009 at 160,000 miles.
By volume the 2016 carries the most reports, with 39; the 2005 has 4. 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.

2005 honda pilot ex with navigation, 81k miles approx. Problem: - no 2 spark plug and thread (coil) blew out during in-town driving, the cylinder head was damaged causing extensive re-condition expense. - all spark plugs are believed to be the originals, we have no re-collection that any spark plug has been replaced since we have not reached the manufacturer's recommended tune up schedule of 105k miles. Service history we bought the car new in ca back in dec 2004. We followed all recommended maintenance schedules by honda. All services, except a recent oil change, were done by honda dealerships across the countries. The recent oil change was done by a local garage, and no work has been performed on the spark plugs as confirmed by the garage owner. Communications with honda - based on my discussion with honda america on nov 19. 2010, they were willing to open a case in order to track the complaint. However, they will not investigate the matter further since my car is out of warranty. Investigation: we believe there may be a latent defect on certain spark plug (or on the engine itself) in certain honda pilot. Based on my research, a…
While driving on city road I heard a loud bang and smoke appeared under the vehicle. The vehicle then started running very rough so I pulled off the side of the road. I got out of vehicle and found a coil laying on the ground along with some other plastic pieces. I had the vehicle towed to my mechanic. My mechanic examined the vehicle and found that a spark plug had blown completely out of the engine block head along with the blown coil that I had picked up. The spark plug was never recovered even though I returned to the scene of the incident.

How far this goes
This page is kept out of search results because 4 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 4 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 misfire or rough idle happen on the 2005 Honda Pilot?
Across 4 owner reports that included an odometer reading, half were filed by 75,000 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 misfire or rough idle on the 2005 Honda Pilot?
4 reports have been filed with NHTSA, about 0.0 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.
