Control module (ECM/PCM/BCM) failure on the 2005 Honda Odyssey
3 crashes 3 of the 13 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 control module (ecm/pcm/bcm) failure gets reported
Owners of the 2005 Honda Odyssey report control module (ECM/PCM/BCM) failure at a median of 50,000 miles. A quarter of the reports come in before 35,000 miles and a quarter after 95,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 20th most-reported problem on this model year.
The mileage distribution
The reported range runs from 35,000 miles at the tenth percentile to 95,000 miles at the ninetieth, a spread of 61,130 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
9% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 36,200 miles | 36,200 miles | 48,000 miles | 96,000 miles | 97,330 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, 3 a crash 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 $700–$3,000 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 12 model years of this car. It shows up earliest on the 2019, at a median of 15,000 miles, and latest on the 2000 at 105,000 miles.
By volume the 2019 carries the most reports, with 35; the 2005 has 13. 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.
Dt: the contact stated the air bag sensor light stayed on. She received a NHTSA recall 05v344000 concerning the air bag sensor. The dealership replaced the air bag sensor, but the light was still on. *ak updated 12/11/2005. A hole in the under side of the bumper allowed small rocks and peddles in the bumper. The weather stripping on the rear doors is pulling away and bending outward. *nm
Tl*- the contact owns a 2005 honda odyssey. The contact was experiencing steering problems related to recall #05v039000. While driving 50 MPH the contact lost control of the vehicle and crashed into a ditch. While attempting to gain control of the steering the vehicle moved from the left to the right. The contact called the police, and was not given a police report. The mechanic replaced the tires, and stated that the failure was due to the tires. The contact advised the mechanic of the steering recall ,and he denied that it was related. None of the air bags in the vehicle deployed at the time of the collision. Recall #05v344000 was related to the air bags: frontal:sensor/control module. The drivers side door was difficult to close unless pressure was applied. The weather was not a factor. The current and failure mileage was 36,200. *ak

How far this goes
Complaints are voluntary, so 13 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 control module (ecm/pcm/bcm) failure happen on the 2005 Honda Odyssey?
Across 11 owner reports that included an odometer reading, half were filed by 50,000 miles. A quarter were filed before 35,000 miles and a quarter after 95,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is control module (ecm/pcm/bcm) failure on the 2005 Honda Odyssey?
13 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.
