Control module (ECM/PCM/BCM) failure on the 2006 Chevrolet Malibu
1 crash 1 of the 22 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 2006 Chevrolet Malibu report control module (ECM/PCM/BCM) failure at a median of 70,000 miles. A quarter of the reports come in before 40,000 miles and a quarter after 95,000 miles, from 19 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 16th most-reported problem on this model year.
The mileage distribution
The reported range runs from 15,000 miles at the tenth percentile to 130,000 miles at the ninetieth, a spread of 119,070 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
26% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 13,130 miles | 37,500 miles | 70,000 miles | 93,550 miles | 132,200 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 24 model years of this car. It shows up earliest on the 2019, at a median of 15,000 miles, and latest on the 2013 at 110,000 miles.
By volume the 2010 carries the most reports, with 97; the 2006 has 22. 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.
Tl*the contact owns a 2006 chevrolet malibu classic. The contact stated that the anti-theft system automatically shuts itself down as well as the engine. The light illuminates and once the vehicle shuts off, she must leave the ignition in the on position before it can restart. The failure has occurred several times and the contact has had to wait ten minutes or more for the vehicle to restart. The manufacturer's manual does not state how to stop this failure. This failure should only occur when someone is attempting to steal the vehicle, but always occurs while the contact is driving. She paid over $700 to repair the vehicle and six months later, the failure recurred. The engine size was unknown. The current mileage is 38,000 and failure mileage was 35,000.
Tl*the contact owns a 2006 chevrolet malibu. While driving 15 MPH on black ice, the vehicle struck a guard rail head-on. There were no injuries. The body shop repaired the vehicle and, a week later, the contact noticed that the engine remains on even when the key is not in the ignition. The dealer stated that the issue was due to the body control module, which was located underneath the dashboard. The insurance company and manufacturer stated that the failure would not be covered. The contact believes that the failure was due to a manufacturer defect, not the crash. The vehicle has not yet been repaired for the ignition failure. The current and failure mileages were 91,000.
Tl*the contact owns a 2006 chevrolet malibu. The contact stated that the brake lights remained illuminated and would shut off when the brake pedal was depressed. The dealer replaced the brake pedal sensor. The following day, the contact could not get shift out of park and the ABS braking system exhibited a noise when the brake pedal was depressed. The dealer stated that since the brake pedal sensor did not repair the failure, the ECM may need replacing. The vehicle was not repaired until the dealer spoke with the manufacturer. The failure mileage was 25,000 and the current mileage was 32,000. Updated 11/11/10 *bf

How far this goes
Complaints are voluntary, so 22 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 2006 Chevrolet Malibu?
Across 19 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 40,000 miles and a quarter after 95,000 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 2006 Chevrolet Malibu?
22 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.
