Complete engine failure or seizure on the 2002 Lincoln Navigator
Only 3 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 complete engine failure or seizure gets reported
There are 3 reports of complete engine failure or seizure on the 2002 Lincoln Navigator, 3 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 105,000 miles. It is the 5th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 40,000 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
Putting it right typically runs $4,500–$12,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure, every year of the Lincoln Navigator
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.
Used car purchased with new car warranty (36000 miles). Car inspected after purchase by lincoln dealer, but 4000 miles later engine seized. Sludge was found to be in engine. No warning of engine shut-down prior to seizure. Ford denies warranty claim due to sludge in engine despite proof of vehicle being serviced by prior owner. *ak

I think this is a common tactic by ford and the justice department should look into it. I leased a new 2002 navigator and had a similar situation. On a road trip in 2004 with 32000 miles, the engine seized. The dealer claimed there was sludge in the engine and ford would not honor the warranty. Apparently, the lease included free oil changes at the dealer, which I was not aware of. I produced all of the receipts to show that I had the oil changed every 3000 miles (more frequently than required) but was told it was irrelevant since I didn't have the dealer do the oil changes. I was told the engine replacement would cost $12,000. The ford dealer was so upset by this he offered to do it for cost, about $4500, but I just walked away, even though they sued and put a $15,000 blot on my credit rating.this was my third navigator lease, including a 1998 and 2000 model before this. I paid top dollar for their most expensive vehicle and this is how they treat good customers. Not to mention being stranded in the desert with my wife and five kids. I will never buy another ford again. One last point - I had just had the oil changed before I…

How far this goes
This page is kept out of search results because 3 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 3 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 complete engine failure or seizure happen on the 2002 Lincoln Navigator?
Across 3 owner reports that included an odometer reading, half were filed by 40,000 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 complete engine failure or seizure on the 2002 Lincoln Navigator?
3 reports have been filed with NHTSA, about 0.0 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.
