ABS module or sensor failure on the 2002 Chevrolet Avalanche
17 crashes 5 injuries 4 deaths 26 of the 64 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 2002 Chevrolet Avalanche report ABS module or sensor failure at a median of 57,500 miles. A quarter of the reports come in before 37,500 miles and a quarter after 82,500 miles, from 46 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 27,500 miles at the tenth percentile to 92,500 miles at the ninetieth, a spread of 65,000 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.
22% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 26,500 miles | 37,250 miles | 57,800 miles | 83,000 miles | 91,500 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
Of these reports, 17 a crash, 5 an injury and 4 a fatality 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 4 model years of this car. It shows up earliest on the 2004, at a median of 45,000 miles, and latest on the 2007 at 185,000 miles.
By volume the 2002 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
2nd time ABS failed, the pedal hit the floor while braking which caused an accident. The first time was august 2002 and the last one was march 31st 2003. Each time damage was extensive and the dealer found nothing wrong with the ABS
Front brakes rattle when going over pot holes and speed bumps at any speed. Rattle goes away when applying the brakes. 2 dealers stated that only oem chevrolet pads can be used when doing a break job on the front/rear brakes. Shop that did 2 brake jobs in 48000 miles stated that front and rear brake wear was "unusualy high" for manufacturer parts and installed aftermarket "lifetime" brakes. While the shop (thankfully) will retighten the breaks at no cost as needed, I think this is not a good answer to the prpblem.*ak
While driving on wet pavement at approximately 25 MPH, I attempted to slow my vehicle as I approached an area of flowing water. I applied the brakes as I normally would. The vehicle did not slow up, instead, the back end began to break loose and spin around. The vehicle spun around twice and came to rest against a utility pole. The ABS brakes obvoiusly did not perform as they should have. Instead of slowing the vehicle, they caused the vehicle to go into the uncontrollable spinout.

How far this goes
Complaints are voluntary, so 64 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 Avalanche?
Across 46 owner reports that included an odometer reading, half were filed by 57,500 miles. A quarter were filed before 37,500 miles and a quarter after 82,500 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 Avalanche?
64 reports have been filed with NHTSA, about 0.5 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.
