Control module (ECM/PCM/BCM) failure on the 2009 Kia Sorento
Only 4 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When control module (ecm/pcm/bcm) failure gets reported
There are 5 reports of control module (ECM/PCM/BCM) failure on the 2009 Kia Sorento, 4 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 92,000 miles. It is the 6th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 29,804 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 $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 11 model years of this car. It shows up earliest on the 2005, at a median of 100 miles, and latest on the 2012 at 100,000 miles.
By volume the 2013 carries the most reports, with 26; the 2009 has 5. 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 2009 kia sorento. The contact stated the passenger air bag off light illuminated on the console with the passenger seat occupied. The failure was intermittent. The vehicle was taken to an authorized dealer where the contact was informed that the air bag sensor was defective. The dealer made repairs to the sensor yet the failure persisted sporadically. The vehicle was taken back to the authorized dealer where an investigator from the manufacturer examined the vehicle and stated the vehicle was operating as normal. The vehicle was not repaired. The failure continued to recur intermittently. The failure mileage was 2,000 and the current mileage was 6,920.
Shortly after buying SUV in 2009 we experienced "querky" stuff like doors relocking, dome light s coming on, back hatch unlocking all this happening on their own!! I kept telling the dealership at oil changes! They kept ignoring it all! Nov 1, 2009 kia electric system service bulletin #282603 (ts b-044) issued. September the check engine and esc off lights started coming on together, SUV immediately decends to 15-20 MPH! You can't give it gas, only rpms rise high! Gas is eaten up! Coast to side, sit a few to 20 minutes. Maybe both or esc off light(s) go out and you proceed. Have noticed a buck feeling before light(s) are coming on at times. Check engine lights may stay on for a while or not. Habitually erratic when lights come on, can be every mile to several miles! Last week SUV with out these lights started running real rough at idle and driving. To the point of reving over 2000 rpms but acted like being held back! I have been reluctant to drive it much in fear of the advancing issues and hurting the power train! At idle range is 300 ' 1,800+ rpms, mechanic witnessed the varying rpms when code 1611 (time out:ECM,PCM,tcm issue)…

How far this goes
This page is kept out of search results because 5 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 5 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 2009 Kia Sorento?
Across 4 owner reports that included an odometer reading, half were filed by 30,000 miles. A quarter were filed before — and a quarter after —. 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 2009 Kia Sorento?
5 reports have been filed with NHTSA, about 0.2 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.
