Other electrical problem on the 2003 Chevrolet Silverado
1 crash 6 fires 1 injury 1 death 9 of the 46 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 Chevrolet Silverado report other electrical problem at a median of 47,500 miles. A quarter of the reports come in before 22,500 miles and a quarter after 65,000 miles, from 38 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 97,500 miles at the ninetieth, a spread of 93,749 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.
32% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 4,400 miles | 21,810 miles | 48,213 miles | 65,185 miles | 98,149 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, 1 a crash, 6 a fire, 1 an injury and 1 a fatality are 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 21 model years of this car. It shows up earliest on the 2014, at a median of 5,000 miles, and latest on the 1997 at 190,000 miles.
By volume the 2003 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
Erg valve failed 4-6 times. Standard alarm on truck turns on and off by its self. Doors lock and unlock by themselves. Loses power to the vehicle while driving. When you open the glove box the cargo light comes on. *la

Lights for instrument panel occasionally does not work. Battery died. Radio made loud humming noise even when car shut off overnight. Air conditioner broke. But the continual problem is the 4WD becomes inoperable and service 4WD message appears. Gm has no repair. They state I must stop turn off the vehicle and restart it in order to "wake up" the electronics. It has been in the repair shop 4 times in last six months when I bought it new. The dangerous part is while driving in ice and snow the vehicle's 4WD became inoperable resulting in loss of control of vehicle and a near miss crash. *cb

How far this goes
Complaints are voluntary, so 46 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 electrical problem happen on the 2003 Chevrolet Silverado?
Across 38 owner reports that included an odometer reading, half were filed by 47,500 miles. A quarter were filed before 22,500 miles and a quarter after 65,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other electrical problem on the 2003 Chevrolet Silverado?
46 reports have been filed with NHTSA, about 0.4 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.
