ABS module or sensor failure on the 2002 GMC Envoy
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 abs module or sensor failure gets reported
There are 9 reports of ABS module or sensor failure on the 2002 GMC Envoy, 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 95,000 miles. It is the 21st most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 28,000 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 $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 3 model years of this car. It shows up earliest on the 2003, at a median of 15,000 miles, and latest on the 2002 at 30,000 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.

Below is copy of letter given to gm dealership following the engine failure at high speed: 10/05/2001 to : bob ross service department 2002 gmc envoy 3,240 miles problem: on sunday october 4th, my wife was driving on 675 to fairfield mall from our home at 6:10 pm in the evening. She had traveled about 8 miles and was going 65 MPH in the middle lane when the envoy suddenly lurched and then quickly slowed with total loss of engine power. The headlights (it was dark) were still on and the check ABS light came on as she coasted to the berm in moderate traffic. At that point the car would turn over (battery ok) with the key but would not fire. She called on-star and they said it would have to be towed and called dispatch (case 00244572). She also called me so that I could pick her up. When I got to the car, approximately 6:15, I turned over the engine and it fired. The check ABS lamp was still on. I waited for the tow truck and he followed me to the bob ross dealership. As I started to drive, the ABS lamp went out, but the check engine soon lamp came on and stayed on the entire drive to the dealership (about 8 miles) where it was…
Several months ago while driving at any speed and when depressing the brakes consumer felt pulsation in the brake pedal. Currently, when the brakes are depressed the pulsation is very severe. Dealer has made an appointment to examine the vehicle. Pulsation occurred fifty times in the last few months.*ak
Dt*: the contact stated the ABS engaged at speeds of 30 MPH and below. The stopping distance was increased as a result. There is a NHTSA recall, # 05v379000, regarding the ABS system. The vehicle has the same problems as the recall; however it is not included in the recall due to the VIN. The vehicle was taken to a local dealership for inspection. The dealer can not duplicate the problem and no repairs were made. Updated 03/03/06. *jb

How far this goes
This page is kept out of search results because 9 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 9 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 GMC Envoy?
Across 5 owner reports that included an odometer reading, half were filed by 30,000 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 abs module or sensor failure on the 2002 GMC Envoy?
9 reports have been filed with NHTSA, about 0.1 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.
