Parking brake failure on the 2005 Chevrolet Equinox
2 crashes 1 injury 3 of the 12 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 parking brake failure gets reported
Owners of the 2005 Chevrolet Equinox report parking brake failure at a median of 110,000 miles. A quarter of the reports come in before 70,000 miles and a quarter after 145,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 22nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 40,000 miles at the tenth percentile to 145,000 miles at the ninetieth, a spread of 104,522 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.
13% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 42,123 miles | 69,900 miles | 107,858 miles | 146,645 miles | 146,645 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, 2 a crash and 1 an injury 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 $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 5 model years of this car. It shows up earliest on the 2008, at a median of 35,000 miles, and latest on the 2005 at 110,000 miles.
By volume the 2018 carries the most reports, with 15; the 2005 has 12. 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.
2005 equinox with 73,200 miles. Purchased used/gm certified 11/2008 in illinois. When applying brakes, the brake pedal shimmied and would not budge as if it was stuck. Had to pump it multiple times and use emergency brake to halt vehicle. After the brake pedal became "unstuck" the ABS and traction control lights came on. I parked the vehicle and had it towed to a dealer. *tr
I was driving at approx 35 MPH approaching a curve in the road. I applied the brakes, the car fishtailed and slid sideways off the road, down an embankment. The car then turned heading in the opposite direction, I hit a mailbox, then a phone pole. The entire time my foot was on the brake but the car was not slowing and continued to accelerate. The car then went back up the embankment, hit another mailbox and continued down the road for a very long distance without slowing while my foot was on the brake. Steering was not responding, the car kept accelerating. I put it in neutral, no help, then finally slammed it in park and put the emergency brake on to stop the car. *tr
At approximately 10-30 MPH the cars ABS system engages on its own, both while stepping on the brake peddle and while just driving within that speed range. While trying to come to a stop, the ABS system will engage and will not allow me to stop safely. In one instance I had to yank on the emergency brake and drop the car to a lower get just to avoid hitting the car in front of me. The system will keep engaging until the system times itself out. Then the ABS and tc lights on the dashboard illuminate. I am approximate $1500.00 into this issue at the dealership and still no solution. I have taken the car to my local chevy dealer and they can't seem to figure out the problem. They have replaced the cars fl hub assembly, multiple speed sensors, and the e.b.c.m. Through changing all thing parts still no success. The car is currently there now for further diagnosing. *tr

How far this goes
Complaints are voluntary, so 12 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 2005 Chevrolet Equinox?
Across 8 owner reports that included an odometer reading, half were filed by 110,000 miles. A quarter were filed before 70,000 miles and a quarter after 145,000 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 2005 Chevrolet Equinox?
12 reports have been filed with NHTSA, about 182 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.
