Engine bay fire on the 2002 Ford F-150
6 fires 6 of the 9 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 engine bay fire gets reported
Owners of the 2002 Ford F-150 report engine bay fire at a median of 110,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 125,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 20th most-reported problem on this model year.
The mileage distribution
The reported range runs from 200 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 153,390 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.
25% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 210 miles | 57,415 miles | 108,500 miles | 124,500 miles | 153,600 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, 6 a fire 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 $4,000–$20,000 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 on other years
The same failure is reported on 10 model years of this car. It shows up earliest on the 2016, at a median of 100 miles, and latest on the 1998 at 145,000 miles.
By volume the 2000 carries the most reports, with 23; the 2002 has 9. 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.
My 2002 ford f150 harley davidson pickup truck ejected a spark plug while driving on the highway . This is the third incident of failure and am concerned for my safety as the truck looses power while at highway speeds and could cause an accident . In addition the failing plug this time was one right under the fuel rail and the coil was prevented from continuing to pull out by the fuel rail adding concern that it could puncture and cause an engine fire .when contacting ford they basically took my information and offered no assistance . *nm
While driving down the road, I heard a loud explosion and the engine began running rough. I pulled over and opened the hood. The explosion had dented the inside of the hood. I found a broken coil laying on top of the engine, and the corresponding spark plug laying beneath the engine. I took the vehicle to a mechanic, who re-threaded the spark plug hole and installed a new spark plug. The vehicle performed as usual for about six months, and then the same exact situation occurred, involving the same exact spark plug. The second occurrence, the plug and coil were so damaged that the head could not be re-threaded and repaired. After researching this issue, I found that dozens of other owners have experienced the same problem, which is due to an engine and/or piston defect. The second occurrence required drilling out the affected head, tapping it, and installing a helicoil before the spark plug could be replaced. I am very concerned about this issue, since in addition to the expense and inconvenience this manufacturing defect has caused me, it is extremely dangerous as well. While I have not had an engine fire, other owners of this…
On start up a sparkplug blew out of cylinder head .... 3rd plug to bow out in 8 months over 800.00 per plug to fix then caught on fire under hood......very dangerous to have happen may cause our house to burn down if in garage.... I called ford 4 times no help what so ever.....bad company .....do not advise ......bad ford products....they need to do a class action on ford ..... *tr

How far this goes
Complaints are voluntary, so 9 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 engine bay fire happen on the 2002 Ford F-150?
Across 8 owner reports that included an odometer reading, half were filed by 110,000 miles. A quarter were filed before 55,000 miles and a quarter after 125,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is engine bay fire on the 2002 Ford F-150?
9 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.
