Premature brake pad or rotor wear on the 2002 GMC Envoy
Only 4 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 premature brake pad or rotor wear gets reported
There are 7 reports of premature brake pad or rotor wear on the 2002 GMC Envoy, 4 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 45,000 miles. It is the 24th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 28,500 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 $300–$1,400 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, every year of the GMC Envoy
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.
I noticed the brakes pulsing badly on my 2002 gmc envoy at 27,000 miles. The dealership stated that brakes are covered up to 21,000 miles and rotors covered to 24,000. All 4 rotors and brake pads had to be replaced at my expense. I guess that I shouldn't have assumed that a warranty of 3 years or 36,000 miles meant that everything was covered. How convenient it is for the warranty coverage on brakes and rotors expires prior to the 3 year 36,000 mile warranty. That tells me that gm knows when the cheaper parts they are using are going to fail. The 3 year 36,000 warranty is very misleading. In my 27 years of driving, I've never seen rotor and brake pad failure at 27,000 miles. Good brake parts are vital in the safety of a vehicle, I don't understand how they are allowed to use inferior materials. Thank god my pregnant wife didn't have and accident while driving this vehicle. *ak

When having my 02' envoy serviced and state inspection by my gmc dealer the service manager called and told me, I would need to r/r my front rotors. The pads were half worn but the rotors smooth surface did not exist. It looked like they were not machined thoroughly. Ser. Mgr thought I lived near the shore, stating salt water would usually causes this. I do not live near the shore and do not go the beach. I drive this vehicle to and from work all highway driving. My vehicle has 41225 mi and has always been serviced by gm. I have owned gm vehicles for 38 yrs and the cars with rotors never looked like this. This looks like a manufacturing imperfection. From reviewing the odi list for this vehicle, others have also documented similar complaints. If I did not bring the vehicle in for the state inspection I would never have know this defect existed. This gave me neither warning in braking, stability nor squealing/ticking from early warning system. I should had asked for old rotors or taken a picture. Front rotors and pads replaced at my expense. *tr

How far this goes
This page is kept out of search results because 7 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 7 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 premature brake pad or rotor wear happen on the 2002 GMC Envoy?
Across 4 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 premature brake pad or rotor wear on the 2002 GMC Envoy?
7 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.
