Loss of power steering on the 2006 Chevrolet Impala
When loss of power steering gets reported
Owners of the 2006 Chevrolet Impala report loss of power steering at a median of 40,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 55,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 80,000 miles. It is the 24th most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 65,000 miles at the ninetieth, a spread of 40,262 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
38% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 26,037 miles | 29,895 miles | 40,400 miles | 54,500 miles | 66,299 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 $600–$2,800 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 6 model years of this car. It shows up earliest on the 2007, at a median of 30,000 miles, and latest on the 2009 at 90,000 miles.
By volume the 2014 carries the most reports, with 19; the 2006 has 8. 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.
1. Normal driving speeds between 0 to 55 MPH. Some rapid accelerations max RPM about 4500. 2. Rapid loss of power steering fluid which resulted in extremely heavy steering 3. Towed vehicle to dealer for repair quoted repair is $550. *tr
Pulling out of driveway steering was hard pulled back in and noticed fluid on the pavement which ended up being power steering fluid. Inspected under the hood and found the leak was coming from the return hose from the power steering pump. Took to local chevrolet dealer and it was fixed. After I had my car back for 6 days the same hose blew a hole in it in a different spot. Took to the dealer two days ago and they replaced it again picking up tomorrow. I constantly hear about other having the same problem on chevy's mainly impalas' and it seems to be primarily the 2006 model. This is ridiculous that there is no recall on this. I've called gm and they are no help at all and seem to just ignore this ongoing problem. Something has to be done about this before someone is seriously hurt in an accident due to the loss of power steering. *tr
Last march, 2008 power steering went out of car, so took to mechanic. After paying over $400 to repair hose and power steering pump on car that had only 30,000 miles. Now in february of 2009, less than one year later, I have the same problem with the power steering going out again. I see that there are alot of complaints about this same thing. I think gm should do something about it and launch a recall to fix the problem before someone gets hurt seriously or worse killed. *tr

How far this goes
Complaints are voluntary, so 8 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 loss of power steering happen on the 2006 Chevrolet Impala?
Across 8 owner reports that included an odometer reading, half were filed by 40,000 miles. A quarter were filed before 30,000 miles and a quarter after 55,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is loss of power steering on the 2006 Chevrolet Impala?
8 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.
