ABS module or sensor failure on the 2001 Chevrolet Silverado
25 crashes 4 injuries 29 of the 234 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 abs module or sensor failure gets reported
Owners of the 2001 Chevrolet Silverado report ABS module or sensor failure at a median of 52,000 miles. A quarter of the reports come in before 40,000 miles and a quarter after 72,000 miles, from 168 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 27,000 miles at the tenth percentile to 86,000 miles at the ninetieth, a spread of 59,150 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
20% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 26,750 miles | 39,763 miles | 51,500 miles | 72,000 miles | 85,900 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, 25 a crash and 4 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 2001 has 234. 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.
The ABS light came on and remained on and the ABS motor continued to run even when the engine was turned off. The vehicle was taken vehicle to three different dealerships, however the problem could not be determined. *jb
The ABS sensor failure resulted in service brakes failing to stop the vehicle immediately. The consumer had to depress the brake pedal several times to stop the vehicle. The brake pedal was hard when this occurred. *ak the problem was also present while being repaired. *sc
The consumer experienced problems with the brakes. *jb when the brakes were applied, the brake pedal vibrated and went completely to the floor, there was no pressure in the brake pedal. *ak there was also a grinding noise occurring at the same time. The consumer stated the problem was sporadic. The dealership was unable to duplicate the problem. In some instances, the consumer was unable to stop the vehicle. *jb

How far this goes
Complaints are voluntary, so 234 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 2001 Chevrolet Silverado?
Across 168 owner reports that included an odometer reading, half were filed by 52,000 miles. A quarter were filed before 40,000 miles and a quarter after 72,000 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 2001 Chevrolet Silverado?
234 reports have been filed with NHTSA, about 1.9 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.
