Power steering pump or fluid leak on the 2008 Chevrolet Silverado 2500
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 power steering pump or fluid leak gets reported
There are 3 reports of power steering pump or fluid leak on the 2008 Chevrolet Silverado 2500, 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 100,000 miles. It is the 10th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 22,000 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 carries the most reports, with 8; the 2008 has 3. 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.
I have a 2008 k2500 diesel. The vehicle is used strictly for camping and has only 24,000 miles. Over thanksgiving,I parked vehicle in an off road park. After 2 days parked, I started the truck and had no steering or brakes at all. This had happened several times before but not as bad. After a few minutes idling, steering and brakes came back to normal. I researched the web and found this to be a common problem. Gm has issued several tsbs on the subject and the claim it is "normal" on 2500 series trucks. Nhtsa has also chimed in with NHTSA id number: 10335581. I took the truck into william l. Morris chevrolet in simi valley, ca. The service writer ignored any of my research, the tsbs and the NHTSA info. Instead, they want me to pay $780 to replace the power steering pump, when gm says it is a normal condition. I believe one of 2 things - we have a serious problem that will eventually hurt someone or they are duping people into an unnecessary expense in replacing the pump. I am an mech engineer. I asked them to show me the results of the pressure test and they could/would not. I asked how they arrived at their conclusion and was…

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 power steering pump or fluid leak happen on the 2008 Chevrolet Silverado 2500?
Across 3 owner reports that included an odometer reading, half were filed by 20,000 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 power steering pump or fluid leak on the 2008 Chevrolet Silverado 2500?
3 reports have been filed with NHTSA, about 0.1 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.
