When abs module or sensor failure gets reported

Owners of the 2002 Chevrolet Silverado report ABS module or sensor failure at a median of 46,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 68,000 miles, from 122 reports that carried an odometer reading.

A part like this is normally expected to survive 95,000 miles. It is the 1st most-reported problem on this model year.

The mileage distribution

The reported range runs from 18,000 miles at the tenth percentile to 97,000 miles at the ninetieth, a spread of 79,270 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.

31% of the dated reports were filed under 36,000 miles.

The whole distribution

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, 20 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 $500–$2,400 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 14 model years of this car. It shows up earliest on the 2008, at a median of 1,200 miles, and latest on the 1996 at 105,000 miles.

By volume the 1999 carries the most reports, with 695; the 2002 has 155. 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.

After 3 weeks of ownership we started experiencing several problems with the steering and braking of this vehicle. Steering wheel would "catch" and make thumping noises as we turned right or left sharp turns (slowly). Brakes are going to cause an accident sooner or later as the pedal goes completely to the floor and thumps loudly but does not slow the vehicle when you try to make a moderately sudden stop. We had our truck in for service after owning it for 3 weeks and the idiots at spitzer chevrolet tried to tell us it was the trailer hitch making all the noise.....what a joke

1,500 miles NHTSA complaint 394617 filed 2003-02-19

I have a 2002 chevrolet silverado. The ABS system fails to stop my vehicle in all types of normal situations which has already LED to one accident. This was my first accident ever and thanks to my dealer who said there was no problem with my brakes I am sure this wont be the last accident. The vehicle brake system will freeze up if so much as a pebble vibration is felt, or stopping on a completely smooth and clean road normally. The scary thing is, I never know when my brakes are going to fail, and since there is no difference in between a smooth road or a pothole disabling the brakes I do not feel comfortable in my own vehicle. I have rolled through intersections, rolled through stop signs, and had one accident in this vehicle. I beleive that the chevrolet company needs to correct this problem immediatly, for the liability and safty of all consumers. I am not the only person with brake problems in the chevrolet silverados from 1999 to current, I have met several and they were all told they have no probelms with there vehicles either. We are waitng for chevrolet to correct this faulty brake system. *ak

When on an incline, the driver noticed that the vehicle rolled three to five feet before stopping. The vehicle was taken to the dealer on two separate occasions, however, the mechanics were unable to duplicate the problem. *ak the incident recurred on 3/14/04, in which the vehicle rolled 5 or more feet before stopping. The service dealer was notified and were waiting for a response from gm. *sc *jb

How far this goes

Complaints are voluntary, so 155 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 abs module or sensor failure happen on the 2002 Chevrolet Silverado?

Across 122 owner reports that included an odometer reading, half were filed by 46,000 miles. A quarter were filed before 30,000 miles and a quarter after 68,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is abs module or sensor failure on the 2002 Chevrolet Silverado?

155 reports have been filed with NHTSA, about 1.3 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.
