Other body or interior problem on the 2009 Chevrolet Impala
1 crash 2 fires 2 injuries 5 of the 39 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 body or interior problem gets reported
Owners of the 2009 Chevrolet Impala report other body or interior problem at a median of 60,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 90,000 miles, from 25 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 9th most-reported problem on this model year.
The mileage distribution
The reported range runs from 7,500 miles at the tenth percentile to 105,000 miles at the ninetieth, a spread of 99,138 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.
32% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 6,693 miles | 24,000 miles | 60,000 miles | 89,000 miles | 105,831 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, 2 a fire and 2 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 $200–$2,000 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 18 model years of this car. It shows up earliest on the 2011, at a median of 7,500 miles, and latest on the 2002 at 100,000 miles.
By volume the 2008 carries the most reports, with 75; the 2009 has 39. 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 2009 chevrolet impala. When the contact turned on the air conditioner, after a few minutes a strong odor came out of the air vents in the vehicle. The dealer informed her that there was a build up of mold in the air ducts; however, no repairs were made. The failure has continued to occur. There were no prior warnings.

2009 chevrolet impala vehicles in car pool where I work have front seat headrests that are hard as a brick without any padding over the steel center frame. These hard headrests offer no protection in a rear end collision and will kill the front occupants. Sides of front of the headrest are padded but not center. *tr
A dead battery at the airport parking lot in a 2009 chevrolet impala may not seem like a problem, however there is no mechanical trunk release from inside the vehicle and my back seat doesn't fold down, so I couldn't crawl into the trunk to trip the emergency release, I was unable to get to my jumper cables. Then when I tried to get the key out of the ignition to lock the car to go make a call. Guess what with the battery dead I couldn't get the key out of the ignition either. A huge concern of mine is this; if that car was involved in an accident, where the battery was destroyed, there would not be any means to access the trunk where emergency equipment is stored, such as first aid kits, fire extinguishers. *tr

How far this goes
Complaints are voluntary, so 39 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 body or interior problem happen on the 2009 Chevrolet Impala?
Across 25 owner reports that included an odometer reading, half were filed by 60,000 miles. A quarter were filed before 25,000 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 body or interior problem on the 2009 Chevrolet Impala?
39 reports have been filed with NHTSA, about 0.5 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.
