Loss of braking on the 2003 Chevrolet S10

Only 5 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 loss of braking gets reported

There are 5 reports of loss of braking on the 2003 Chevrolet S10, 5 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 78,000 miles. It is the 17th most-reported problem on this model year.

The whole distribution

Percentiles of the 5 odometer readings owners gave.
10th25thMedian 75th90th
— — 48,500 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 $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 7 model years of this car. It shows up earliest on the 2002, at a median of 15,000 miles, and latest on the 1996 at 100,000 miles.

By volume the 1996 carries the most reports, with 57; the 2003 has 5. 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.

When I hit a small bump my ABS kicked in and I lost alot of braking power, almost caused accident. Brake pedal went to the floor. (earlier date). *ak brake pads completely warn down to squelers after 10,000 miles cost of $160 to replace pads.

11,700 miles NHTSA complaint 521844 filed 2005-02-15

Driving back home from the grocery store. Brake pedal went to the floor. Nursed the truck to the house. Reservoir almost empty. Refilled reservoir with brake fluid. Checked under truck and found that the left rear wheel was coated with brake fluid. Pulled the rear wheel to find the leak. Brake lines coated with fluid. I had my wife come out to pump the brake pedal while I was under the truck. Leak found in the hard line about 2 inches from the flexible line to the hard line connection. *tr

Total sudden brake failure I had to leave the road to avoid other cars. 40mph front right steal line failed and right rear line failed at the same time lines are rusty but the rest of the truck is ok there was no warning signs ( like drips or low level in the booster)

How far this goes

This page is kept out of search results because 5 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 5 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 S10?

Across 5 owner reports that included an odometer reading, half were filed by 50,000 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 loss of braking on the 2003 Chevrolet S10?

5 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.
