Seat belt or retractor failure on the 2004 Lincoln Navigator
3 injuries 3 of the 5 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.
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 seat belt or retractor failure gets reported
There are 5 reports of seat belt or retractor failure on the 2004 Lincoln Navigator, 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 82,000 miles. It is the 4th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 132,000 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
Of these reports, 3 an injury 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 $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 4 model years of this car. It shows up earliest on the 2019, at a median of 5,000 miles, and latest on the 1998 at 140,000 miles.
By volume the 2019 carries the most reports, with 12; the 2004 has 5. 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.
Tl*the contact owns a 2004 lincoln navigator. The contact stated that the seat belts in her vehicle would not retract properly. The failure was more noticeable in the driver's seat because it was used more frequently; however, the passenger side seat belt malfunctioned occasionally. The contact was unsure if the rear seat belts malfunctioned because they were hardly used. She discovered a technical service bulletin, which stated that the manufacturer would correct the issue in future models. In the interim, they wanted to charge the contact $160 to place teflon tape in the retractor. She took the vehicle to the dealer and was informed of the tsb and teflon remedy. The vehicle has not been repaired. The manufacturer could not assist. The current mileage was 43,066 and failure mileage was approximately 35,000. Updated 5/7/09 *cn updated 05/08/09.*jb
While driving north on ar hwy 9 a few miles south of malvern, arkansas with my wife in the front passenger seat and my son in the second row directly behind me, a loud bang occurred. In the next moments I realized the side curtain air bags deployed on both sides of the vehicle, a smell like fireworks became immediately apparent, and the driver's side sun visor was destroyed and hanging down directly in front of me at an angle. I was able to maintain control of the vehicle and stay in my lane of the two-lane highway and slowed down. After shortly realizing what happened, I looked for a place to pull over, did so, and took my pocket knife and cut away the side curtain airbags to be able to see out of the side windows and continue our trip north. I found the driver's visor vanity mirror had shattered in pieces in my lap and on the floor, along with other parts from the visor which now hung down at a steep angle. Both the driver's side and passenger side front seat belts were damaged, and the driver's seat belt upper anchor would no longer stay locked in position, sagging to its lowest position by gravity. Later that day I discovered…

How far this goes
This page is kept out of search results because 5 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 5 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 Lincoln Navigator?
Across 4 owner reports that included an odometer reading, half were filed by 130,000 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 seat belt or retractor failure on the 2004 Lincoln Navigator?
5 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.
