Other wheel or tire problem on the 2009 Chevrolet Impala
When other wheel or tire problem gets reported
Owners of the 2009 Chevrolet Impala report other wheel or tire problem at a median of 25,000 miles. A quarter of the reports come in before 20,000 miles and a quarter after 90,000 miles, from 20 reports that carried an odometer reading.
A part like this is normally expected to survive 60,000 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 130,000 miles at the ninetieth, a spread of 125,872 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.
60% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 4,928 miles | 19,972 miles | 25,610 miles | 89,510 miles | 130,800 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 $200–$1,500 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 1996, at a median of 23 miles, and latest on the 2002 at 120,000 miles.
By volume the 2007 carries the most reports, with 61; the 2009 has 23. 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.
My car prematurely wears front tires out. By 4200 miles, my front tires were showing the cords. I had own a 2008 impala (same model) and at 4000 miles the front tires were bald. This has been constant with this vehicle and the previous vehicle. The dealer has aligned this vehicle and states that there is no problem!! If I wasn't aware of this, my tires would blow out!!!!! *tr
Tl*the contact owns a 2009 chevrolet impala. The contact stated that the front tires have worn very rapidly. Upon researching the failure the contact stated that the recommended psi is 44 but the manufacturer recommended 30 psi. During routine maintenance the contact was informed that he should purchase new tires and have the alignment done again. The vehicle was not repaired. The failure mileage was 18,500 and the current mileage was 19,886.
This is a copy of a complain that has been sent to the chevrolet div. Of general motors. Chevrolet customer assistance center po box 33170 detroit, mi 48232-5170 [xxx] sept. 23, 2010 re: warranty deception ( vehicle 2009 impala) this vehicle is still under warranty with odometer reading of 27,000 miles. A stud broke off the rt rear wheel and the larry green service dept.in cottonwood, arizona refused to repair it under the bumper to bumper warranty. They claimed it was sheared off by whomever rotated the tires last. My claim was that the tires were never rotated and the stud broke. I also claim that it doesn't make any difference because no matter when and if the tires were rotated at some time in the future a stud may break by road impact. If it can be proven that the stud is defective it may result in a massive recall. How much torque is required to twist off a stud with a standard wrench? They also claim that the stud didn't come from the factory defective. That is an assumption. ( of course without testing the stud it is unknown.) with that logic anything that breaks can be excused as an existing cause. The 3 year warranty is…

How far this goes
Complaints are voluntary, so 23 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 wheel or tire problem happen on the 2009 Chevrolet Impala?
Across 20 owner reports that included an odometer reading, half were filed by 25,000 miles. A quarter were filed before 20,000 miles and a quarter after 90,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other wheel or tire problem on the 2009 Chevrolet Impala?
23 reports have been filed with NHTSA, about 0.3 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.
