Loss of braking on the 2003 Chevrolet Silverado
2 crashes 1 injury 3 of the 80 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 loss of braking gets reported
Owners of the 2003 Chevrolet Silverado report loss of braking at a median of 82,500 miles. A quarter of the reports come in before 52,500 miles and a quarter after 100,000 miles, from 72 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 30,000 miles at the tenth percentile to 130,000 miles at the ninetieth, a spread of 99,856 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
17% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 30,059 miles | 52,250 miles | 82,202 miles | 99,201 miles | 129,915 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, 2 a crash and 1 an injury 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 $400–$3,000 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 15 model years of this car. It shows up earliest on the 2015, at a median of 15,000 miles, and latest on the 1996 at 190,000 miles.
By volume the 1999 carries the most reports, with 103; the 2003 has 80. 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.
Consumer states that when trying to apply the anti-lock brakes, they locked up, which caused extended stopping distance. Dealer notified. *ak when accelerating between 45-56 MPH, the anti-lock brake failure occurred and the antilock brake indicator light came on. *tt *jb
While applying the brakes, the pedal went to the floor. The driver pumped the brake pedal and the brakes released power. The consumer was able to drive the vehicle to the dealer for analysis. *jb *jb
I have a 2003 chevrolet silverado 1/2 ton pickup with 29000 miles on it when the rear brake calipers froze up and ruined my rear brake pads. Chevy says that this is not under warranty because of poor maintenance on my part. I did everything required in the owners manual. I have talked with three of my friends who have the same pickup and their rear brakes failed at lower mileages and were covered and the dealer also installed a special brake dirt cover to the rear brakes to help with the problem. I contend that this is a design defect in the rear disc brakes and can expect to replace my rear brakes in another 18000 t0 24000 miles. Would you look into this matter for me.

How far this goes
Complaints are voluntary, so 80 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 loss of braking happen on the 2003 Chevrolet Silverado?
Across 72 owner reports that included an odometer reading, half were filed by 82,500 miles. A quarter were filed before 52,500 miles and a quarter after 100,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is loss of braking on the 2003 Chevrolet Silverado?
80 reports have been filed with NHTSA, about 0.7 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.
