Control module (ECM/PCM/BCM) failure on the 2007 Chevrolet Aveo
1 crash 1 of the 14 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 control module (ecm/pcm/bcm) failure gets reported
Owners of the 2007 Chevrolet Aveo report control module (ECM/PCM/BCM) failure at a median of 2,000 miles. A quarter of the reports come in before 200 miles and a quarter after 70,000 miles, from 12 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 46 miles at the tenth percentile to 90,000 miles at the ninetieth, a spread of 87,668 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.
58% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 46 miles | 239 miles | 1,950 miles | 67,500 miles | 87,714 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 is 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 $700–$3,000 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 6 model years of this car. It shows up earliest on the 2007, at a median of 2,000 miles, and latest on the 2008 at 75,000 miles.
By volume the 2006 carries the most reports, with 20; the 2007 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.
(1)passenger seat airbag sensor malfunction/ no-fix/ thus no repair purchase new car01/20/07 and airbag light alerts occupants that (2) airbag is not engaged even when an adult is sitting in passenger seat. Problem is intermittent. Took car into dealer service after a week . Consequence of failure is upon a front end collison, airbag would not deploy causing increased injury to passenger occupant. (3) dealer service/chevrolet and gm state there is no fix thus no repair has been done and vehicle has been in shop since feb 2nd, just two weeks after purchase. Dealer service and gm tell me that it is a 'design problem' and even replacing the seat would not correct problem as error is within seating mechanism as well. *** service/gm stated it was my fault as "customer to wide" asked my family to come to dealership. Service manager inspected family then said that couldn't be it. Now they are claiming, "not weigh enough" for seat to pick sense someone in seat. My family members weigh between 125-170 lbs.
The passenger airbag off indicator light on the dashboard remained on when the passenger seat was occupied. This was intermittent, but more likely the indicator light was on, rather that not, indicating the passenger airbag would not deploy in the event of a collision. *ak

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 control module (ecm/pcm/bcm) failure happen on the 2007 Chevrolet Aveo?
Across 12 owner reports that included an odometer reading, half were filed by 2,000 miles. A quarter were filed before 200 miles and a quarter after 70,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is control module (ecm/pcm/bcm) failure on the 2007 Chevrolet Aveo?
14 reports have been filed with NHTSA, about 0.6 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.
