Seat belt or retractor failure on the 2001 Ford F-250 SD
When seat belt or retractor failure gets reported
Owners of the 2001 Ford F-250 SD report seat belt or retractor failure at a median of 125,000 miles. A quarter of the reports come in before 85,000 miles and a quarter after 155,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 82,000 miles. It is the 6th most-reported problem on this model year.
The mileage distribution
The reported range runs from 45,000 miles at the tenth percentile to 195,000 miles at the ninetieth, a spread of 147,949 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.
10% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 44,851 miles | 85,630 miles | 126,000 miles | 157,250 miles | 192,800 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 $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 6 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 2001 at 125,000 miles.
By volume the 2001 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
Front passenger seat belt continues to "unclick" itself. Example, passenger "clicks" seatbelt in. Thinks they are safer. Minutes later seatbelt unbuckles itself. Passenger must rebuckle self in continually. On 3/29/2002 ford f250 crew cab truck brought in to theodore robbins ford (costa mesa, ca) for fixing front passenger side seat belt. They said they fixed it. I have receipt saying it was fixed. Seatbelt still to this day uncllicking itself. Called my local ford dealership in michigan on february 22, 2005, they said, sorry, out of warranty, you have to pay to have it fixed......*ak
Driver side seat belt unsnaps while driving, was checked under recall in 2001 and checked ok, now I am having problems. This problem has been going on for about the last six months. *nm
Tl* - the contact stated that the front driver's seat belt did not latch properly on 2001 ford f250. The seat belt will latch, but after a few minutes it will release itself from the latch. The contact has recently noticed the problem with the seat belt because she just started driving the vehicle on 12/19/06. The vehicle currently has 100,000 miles. The contact took the vehicle to the dealer, and was told the seat belt was involved in a recall campaign 01v227002. The rear left seat belt was repaired during the recall. The front driver's seat belt was not replaced because it was inspected and found to be working properly. The contact was told by the dealer that the recall campaign was now closed and they will not repair the seat belt free of charge. *ak updated 2/16/2007 - *nm

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 2001 Ford F-250 SD?
Across 10 owner reports that included an odometer reading, half were filed by 125,000 miles. A quarter were filed before 85,000 miles and a quarter after 155,000 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 2001 Ford F-250 SD?
14 reports have been filed with NHTSA, about 0.3 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.
