Other driver assistance problem on the 2003 Chevrolet Impala

1 crash 1 injury 2 of the 7 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.

Only 6 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.

When other driver assistance problem gets reported

There are 7 reports of other driver assistance problem on the 2003 Chevrolet Impala, 6 with a mileage attached. That is too few to place the failure on the odometer with any confidence.

A part like this is normally expected to survive 45,000 miles. It is the 34th most-reported problem on this model year.

The whole distribution

Percentiles of the 6 odometer readings owners gave.
10th25thMedian 75th90th
— — 147,500 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 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–$1,800 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 16 model years of this car. It shows up earliest on the 2016, at a median of 50,000 miles, and latest on the 2003 at 150,000 miles.

By volume the 2011 carries the most reports, with 102; the 2003 has 7. 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.

Abs traction control lights on intermittently for 3 years. Had this checked by dealer numerous times and was not able to diagnose a problem. The lights now stay on for the last 8 months. *tr

100,000 miles NHTSA complaint 936898 filed 2012-08-30

The service traction control light is on the dash panel and my car started to shake and pull to one side when the brakes were applied. The problem quickly grew into the cat constantly pulls to one side and the steering feels sloppy and loose if that makes sense. The traction control doesn't work but will randomly kick in while driving and the car instantly feels as if the brakes are being applied and grinder but the worse part is how the pulling to one side becomes a quick grab and jerk to one side and has nearly caused me several accidents and I cannot relax and drive. I am always tense and ready to fight to keep my car going straight and now with the bad michigan winter its impossible to drive on some days. I've been told that I need a new traction control pump which is going to cost around $2500 and up depending on what they find but will automatically start at $2500. That cost is ridiculous and I have talked to prob approx a hundred people who either had the same problem or knew of someone who does, over the past few years. My car is now parked and I have to beg for rides to work because its winter and I cannot put myself and…

100,000 miles NHTSA complaint 1028820 filed 2013-12-27

My turning signals work on and off all of a sudden. The first time it happened I was on the freeway and was attempting to get over and my right turning signal wouldn't work but the left turning signal worked fine. Then after a day or two the right turning signal would work but then the left turning signal won't work. Then all of a sudden they would both work then both stop working. Now a month has passed and neither one of them work most the time, but will work for a hot second and then stop working. This is only for the rear turning signal though the front turning signal have always worked properly and still do.

How far this goes

This page is kept out of search results because 7 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.

Complaints are voluntary, so 7 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 other driver assistance problem happen on the 2003 Chevrolet Impala?

Across 6 owner reports that included an odometer reading, half were filed by 150,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other driver assistance problem on the 2003 Chevrolet Impala?

7 reports have been filed with NHTSA, about 0.1 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.
