Power steering pump or fluid leak on the 2003 Chevrolet Silverado 2500
When power steering pump or fluid leak gets reported
Owners of the 2003 Chevrolet Silverado 2500 report power steering pump or fluid leak at a median of 140,000 miles. A quarter of the reports come in before 80,000 miles and a quarter after 200,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 100,000 miles. It is the 17th most-reported problem on this model year.
The mileage distribution
The reported range runs from 80,000 miles at the tenth percentile to 210,000 miles at the ninetieth, a spread of 128,000 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 80,000 miles | 80,000 miles | 140,000 miles | 202,000 miles | 208,000 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 $350–$1,600 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 6 model years of this car. It shows up earliest on the 2000, at a median of 5,000 miles, and latest on the 2002 at 210,000 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.
Dt*: the contact stated while traveling 50 MPH, power steering was lost and braking became harder. The vehicle was pulled over and power steering fluid was replaced, but that did not correct the problem. The vehicle was driven to the residence and the power steering pump was replaced, this did not repair the problem. The dealership determined there was a collapsed hose. The hose was replaced, but the problem persisted. There was a NHTSA recall, # 04v045000, regarding the brakes. The vehicle was not included in the recall due to the VIN.

My 2003 chevrolet 2500hd truck has had the power steering pump go out three times. When it goes out the steering and brakes fail and make it very hazardous to continue requiring me to stop and have some one pick up my truck and haul it home. I've also had my air conditioning go out twice and is nearing failure again. The front hub assembly has also gone out twice on this truck. Once the repair was made under warranty. *tr

How far this goes
Complaints are voluntary, so 8 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 power steering pump or fluid leak happen on the 2003 Chevrolet Silverado 2500?
Across 8 owner reports that included an odometer reading, half were filed by 140,000 miles. A quarter were filed before 80,000 miles and a quarter after 200,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is power steering pump or fluid leak on the 2003 Chevrolet Silverado 2500?
8 reports have been filed with NHTSA, about 27 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.
