Other engine problem on the 2004 Lincoln Navigator
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 other engine problem gets reported
There are 5 reports of other engine problem 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 95,000 miles. It is the 5th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 71,888 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 $300–$4,000 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 13 model years of this car. It shows up earliest on the 2015, at a median of 40,000 miles, and latest on the 2000 at 145,000 miles.
By volume the 2019 carries the most reports, with 15; 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.
Dt*: the contact stated while driving 70mph on the interstate, the speed decreased to 50mph followed by the illumination of the check engine light. The vehicle was seen by a dealer. The mechanic determined the vacuum module on the engine failed. The engine vacuum module was replaced by the dealer.
In nov 05 the car started to shut off momentarily as you started to drive, it would do it only when you would take off from a stop and never at freeway speeds. This would occur 50% of the time. The dealer had it on 11-7 and replaced the cam position sensor. When I picked it up on 11-8 it was worse than before. I returned it on 11-9 they returned it on 11-19 after replacing one of the coils. This helped but didn't solve the problem, still had the hesitation leaving a stop but only happened 2-3 times in the 1st week. In the 2nd week as I slowed down for a stop it shut completely off, when I put it in neutral , turned the ignition off and back on it started. It continued to hesitate at time when you were driving in city traffic but would not shut completely off. This past week the hesitations became more frequent and on tugs 5-16 it shut down totally in heavy traffic as I turned a corner. I delivered the car back to the dealer in the afternoon, he call and said nothing could be found and could one of the techs drive it home for a test drive, I agreed. He called and reported the car runs perfect and they can't do anything if they…
For the past 6-8 months my vehicle has sporadically stalled/stopped for no apparent reason. When it stops like this it can occur on the highway or surface streets without notice. I have taken it to the lincoln dealer two times with the last time being told it was a transmission problem, which I was skeptical, because of no previous problems. I have requested assistance from ford motor who essentially dismissed without any liability due to the car being out of warranty. I am requesting your assistance before there is any injury, accident or fatality. I have the e-mail correspondence with ford. *tr

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 other engine problem happen on the 2004 Lincoln Navigator?
Across 4 owner reports that included an odometer reading, half were filed by 70,000 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 other engine problem 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.
