Parking brake failure on the 2002 Chevrolet Tahoe
When parking brake failure gets reported
Owners of the 2002 Chevrolet Tahoe report parking brake failure at a median of 50,000 miles. A quarter of the reports come in before 20,000 miles and a quarter after 75,000 miles, from 22 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 15,000 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 137,740 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
36% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 15,260 miles | 20,750 miles | 50,314 miles | 74,482 miles | 153,000 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 $250–$1,300 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 8 model years of this car. It shows up earliest on the 1999, at a median of 10,000 miles, and latest on the 2004 at 160,000 miles.
By volume the 2001 carries the most reports, with 71; the 2002 has 28. 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.
Emergency brake on tahoe's go out if you do not use them and cost around $500. To fix the problem.from people I have talked to gm knows about the problem but does not care and refuses to fix.I understand that this problem is on all tahoe and suburbans years 2002 and 2003.to pass a safety test in texas you haven't to have an emergency brake that works.I was told that you have to use this brake on it will happen again.I don't park on a hill so I don't use it.others are the same.
The emergency brake did not keep the vehicle from moving. The consumer was able set the emergency brake and the vehicle would still move. It was replaced less than one year ago, but the problem recurred. The work was performed by the local mechanic. *ak once the brake was set and was stressed, the shoe would fail. *sc *jb
I had a 2002 chevy tahoe. About 1 year into owning the vehicle, strange brake noises occured intermittenly. It also was getting very poor gas mileage, down about 2-3 miles per gallon. I brought it in several times to brown and brown at superstition springs and asked them to check the brakes, which they never did. Finally, after about 6-8 months of this problem, the issue was identified after my family and I were driving home one night and we smelled brakes burning. I took the tahoe back to brown and brown the next day. They found that the emergency brake had been stuck on the brakes for months, and finally burned up. The problem was fixed, under warranty, but with no apologies from chevy. Unfortuneately, I had already received compensation from chevy for other issues relating to this tahoe. So I could not file a lemon law suit again. I ended up trading the vehicle in for another, due to all the issues. The vehicle was just constantly in the shop.*ak

How far this goes
Complaints are voluntary, so 28 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 parking brake failure happen on the 2002 Chevrolet Tahoe?
Across 22 owner reports that included an odometer reading, half were filed by 50,000 miles. A quarter were filed before 20,000 miles and a quarter after 75,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is parking brake failure on the 2002 Chevrolet Tahoe?
28 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.
