Misfire or rough idle on the 2006 Honda Accord
Only 2 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 2 reports of misfire or rough idle on the 2006 Honda Accord, 2 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 42nd most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 78,616 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 20 model years of this car. It shows up earliest on the 2016, at a median of 6 miles, and latest on the 1997 at 170,000 miles.
By volume the 2018 carries the most reports, with 87; the 2006 has 0. 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.
My fiancee, her brother, our 22-month old son , and myself were on the highway (270s) to reagan international airport at 6:30 pm when the car suddenly slowed down, would not accelerate, and started shaking. Not knowing what was going on I pulled over, turned the engine off, and got out of the car. I walked around the car and everything was fine. I got back in the car, started the engine and stepped on the gas pedal without much of an acceleration. We called a friend who is a mechanic and he said that it was probably a spark plug issue. We were able to drive the car the next day to his shop and the diagnostics was cylinder misfiring. It turned out that a spark plug became loose,melted, and destroyed the cylinder. He fixed the treads where the spark plug screws into the engine but the engine did not pressurize. He went inside the engine and discovered that there were lot of loose debris in the engine and the smooth surface against which the cylinder glides in the engine was damaged and was very rough. His recommendation was to replace the engine, which he is currently doing for a minimum of $2500 out of pocket since the warranty…
In january, three weeks after driving 1000 miles to florida the engine started to miss and with in a mile I could not go 10 miles a hour. I had the car towed to the fort myers, florida honda dealer. I was told one of the rear spark plugs was loose and the blow-by over-heated the spark plug causing the inside of the plug to come loose fall inside the head thus causing damage to the engine. The coil mounted to the spark plug was charred indicating very high temperature from the blow-by. The plug was loose in the socket indicating it was not tighten securely. The top of the plug is still in-place on the spark plug. I have the parts. The engine had the fluids check and oil changed every 4000 miles and normal maintenance performed. I do most of my own maintenance and had no reason to check the spark plugs. I keep track of gasoline usage and the car had no change in gas consumption, an indication of bad sparkplugs. Over all usage of 22 m/g. The suggestion of the service manager was that the lease expensive way to get back to my home in ohio was to have a used engine installed. It took over a week. I now have almost $5000 more invested…

How far this goes
This page is kept out of search results because 2 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 2 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 2006 Honda Accord?
Across 2 owner reports that included an odometer reading, half were filed by 80,000 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 2006 Honda Accord?
2 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.
