Other brake problem on the 2008 Chevrolet Impala
2 crashes 2 of the 32 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 other brake problem gets reported
Owners of the 2008 Chevrolet Impala report other brake problem at a median of 37,500 miles. A quarter of the reports come in before 17,500 miles and a quarter after 57,500 miles, from 29 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 11th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 105,538 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
48% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 4,760 miles | 18,000 miles | 36,429 miles | 58,000 miles | 110,298 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 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–$1,800 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 19 model years of this car. It shows up earliest on the 2007, at a median of 15,000 miles, and latest on the 2000 at 120,000 miles.
By volume the 2014 carries the most reports, with 47; the 2008 has 32. 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.

Tl*the contact owns a 2008 chevrolet impala. While driving downhill, the brakes would pulsate abnormally. The dealer road tested the vehicle and found bad pulsations in hard speed stops. Both front rotors exhibited severe heat spots and were warped. The brake pads were replaced with heavy duty brake pads. The vehicle was released to the owner but within 10,000 miles the brakes began to exhibit the same failure. The dealer could not duplicate the failure and advised the contact to down shift on hills to prevent the vibration in the brakes. No additional repairs were made to the vehicle. The failure persisted. The failure mileage was 16,514 and the current mileage was 26,952. Updated 03/24/10 *bf the consumer was told the brakes were safe and no action would be taken.

How far this goes
Complaints are voluntary, so 32 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.

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.
