Seat belt or retractor failure on the 2004 Honda Odyssey
5 crashes 6 injuries 11 of the 14 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 seat belt or retractor failure gets reported
Owners of the 2004 Honda Odyssey report seat belt or retractor failure at a median of 100,000 miles. A quarter of the reports come in before 45,000 miles and a quarter after 145,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 82,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 175,000 miles at the ninetieth, a spread of 165,476 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.
20% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 10,380 miles | 44,000 miles | 102,000 miles | 144,775 miles | 175,856 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, 5 a crash and 6 an injury 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 $200–$900 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 21 model years of this car. It shows up earliest on the 2022, at a median of 500 miles, and latest on the 2006 at 135,000 miles.
By volume the 2005 carries the most reports, with 34; the 2004 has 14. 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.
While driving at any speed and when the consumer depressed the brakes seat belt locked. The belt will relax after thirty seconds or so. This problem occurred three hundred times, at least ten times a day. Consumer claimed that when the belt locked it caused pain. *ak
Dt*: the contact stated while attempting to exit the vehicle the right rear seat belt was twisted around the occupant. The seat belt buckle would not release therefore the seat belt had to be cut. Although the dealer was alerted no inspections have been made.
Dt*: the contact stated while driving 40mph on a country road, the vehicle struck another vehicle resulting in a rear end collision, and the airbags did not deploy. The contact was wearing a seat belt, but minor injuries were sustained. The vehicle was totaled due to the extensive front end damage. The police were alerted, and a report was processed. An insurance adjustor inspected the vehicle and determined the airbags should have deployed. The manufacturer was alerted.

How far this goes
Complaints are voluntary, so 14 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 seat belt or retractor failure happen on the 2004 Honda Odyssey?
Across 10 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before 45,000 miles and a quarter after 145,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is seat belt or retractor failure on the 2004 Honda Odyssey?
14 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.
