Other electrical problem on the 2003 Ford Ranger
4 fires 4 of the 14 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 other electrical problem gets reported
Owners of the 2003 Ford Ranger report other electrical problem at a median of 80,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 135,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 150,000 miles at the ninetieth, a spread of 139,000 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.
27% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 11,000 miles | 31,000 miles | 78,000 miles | 136,150 miles | 150,000 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, 4 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 $250–$2,000 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 15 model years of this car. It shows up earliest on the 2019, at a median of 10,000 miles, and latest on the 1997 at 105,000 miles.
By volume the 1996 carries the most reports, with 31; the 2003 has 14. 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.
Vehicle has died on interstate four times and had to be towed in. Ford customer service at 1-800-392-ford states that they don't want to replace the vehicle. I am told I should continue to get it repaired under warranty. My concern is for the safety of my family when we are waiting hours in a snowstorm for the tow truck to arrive. I have owned 8 fords in the last five years. That is about to change because ford motor states that they have followed the letter of the law concerning repairs under the warranty. We have now replaced one ford with a lexus and are totally amazed at the difference of attitude towards the customer. At our first free lexus oil change my wife was given a dozen long stem roses. What do you think she is saying about ford these days? Now I understand why people are buying more foreign cars and trucks.
While driving at 55 MPH vehicle lost power. This problem occurred six times. Electrical inertia switch was defective. Dealer replaced the switch once, and needs to be replaced again. *ak
I have a 2003 ford ranger, when I apply the brakes the vehicle surges. Forward; I put the truck in park & shut off the ignition. When I restart. It returns to normal. This happens on once in a while. *tr

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.

How common is other electrical problem on the 2003 Ford Ranger?
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.
