When abs module or sensor failure gets reported

Owners of the 2005 Chevrolet Impala report ABS module or sensor failure at a median of 85,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 135,000 miles, from 14 reports that carried an odometer reading.

A part like this is normally expected to survive 95,000 miles. It is the 16th most-reported problem on this model year.

The mileage distribution

The reported range runs from 20,000 miles at the tenth percentile to 150,000 miles at the ninetieth, a spread of 130,450 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.

29% of the dated reports were filed under 36,000 miles.

The whole distribution

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 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 $500–$2,400 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 15 model years of this car. It shows up earliest on the 2000, at a median of 25,000 miles, and latest on the 2007 at 120,000 miles.

By volume the 2013 carries the most reports, with 33; the 2005 has 14. 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.

I was a passenger in an 2005 impala, driver rear ended a large truck, I hit the windshield, neither the anti lock brakes or the air bags worked, about $8,000 damage to impala, none to truck. I did not have seat belt on.*ak

11,000 miles NHTSA complaint 528594 filed 2005-03-30

Traction control system failed on my vehicle. The failure turned off my anti-lock brake system and my traction control system at two inopportune times. This failure has twice in the past few months. It first occurred at the end of december during a snow storm. The second failure occurred a few weeks ago while driving through a rain and hail storm. Both times the vehicle was taken to the dealership to be fixed. The dealer replaced a faulty speed sensor. My car is about a year old and two speed sensor have already failed. I'm upset at the fact that we purchased the car based on its safety features and twice now they have failed, as I mentioned earlier, at the most inopportune moments, where we were relying heavily on said safety features. *nm

How far this goes

Complaints are voluntary, so 14 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 abs module or sensor failure happen on the 2005 Chevrolet Impala?

Across 14 owner reports that included an odometer reading, half were filed by 85,000 miles. A quarter were filed before 30,000 miles and a quarter after 135,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is abs module or sensor failure on the 2005 Chevrolet Impala?

14 reports have been filed with NHTSA, about 0.2 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.
