Premature brake pad or rotor wear on the 2002 Jeep Grand Cherokee
1 crash 1 of the 103 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 premature brake pad or rotor wear gets reported
Owners of the 2002 Jeep Grand Cherokee report premature brake pad or rotor wear at a median of 17,500 miles. A quarter of the reports come in before 12,500 miles and a quarter after 27,500 miles, from 76 reports that carried an odometer reading.
A part like this is normally expected to survive 45,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 50,000 miles at the ninetieth, a spread of 41,350 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
82% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 9,150 miles | 13,000 miles | 17,500 miles | 28,000 miles | 50,500 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, 1 a crash is 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 $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 on other years
The same failure is reported on 11 model years of this car. It shows up earliest on the 2014, at a median of 5,000 miles, and latest on the 1997 at 150,000 miles.
By volume the 1999 carries the most reports, with 381; the 2002 has 103. 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.
Rotors and brakes. I have resurfaced my rotors once and now I am replacing them. I purchased the car new and it is now 12 months and 2 weeks old, much too soon for either of these repairs and replacements. The dealer tells me its my problem, not theirs. I am also having to replace the brake pads for the second time.
My jeep has approx 24,000, predominately highway. Not stop and go traffic, the brakes should not need to be fully replaced. My father has a 2001 and also had to replace his front and rear rotors. I believe that this is a continual problem for jeep and that should be investigated more thoroughly. If a survey was conducted for jeep owners I am sure a prevalent number of owners would share this complaint. To allow this factor to exist in such a popular vehicle is a danger to the consumer and any one who shares the road. *nlm
Brakes shutter when applied. Dealer says warped rotors/ calipers, & pads need replacement, jeep is just out of warranty ,and they want a small fortune to repair a know defect. This is a safty issue that needs to be recalled. *ak

How far this goes
Complaints are voluntary, so 103 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 Jeep Grand Cherokee?
Across 76 owner reports that included an odometer reading, half were filed by 17,500 miles. A quarter were filed before 12,500 miles and a quarter after 27,500 miles. 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 Jeep Grand Cherokee?
103 reports have been filed with NHTSA, about 0.7 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.
