Control module (ECM/PCM/BCM) failure on the 2007 Dodge Caravan
Only 3 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 4 reports of control module (ECM/PCM/BCM) failure on the 2007 Dodge Caravan, 3 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 10th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 10,822 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 12 model years of this car. It shows up earliest on the 2007, at a median of 10,000 miles, and latest on the 2004 at 120,000 miles.
By volume the 2005 carries the most reports, with 50; the 2007 has 4. 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 2007 dodge caravan. The air bag light illuminates intermittently. The light remains illuminated for 20 seconds or 30 minutes. The contact has taken the vehicle to the dealer on approximately four occasions. The first time, they performed a diagnostic and the vehicle passed. The second time, the dealer replaced the clockspring. The third and fourth times, they could not duplicate the failure. The failure mileage was 3,618 and current mileage was 9,000. The consumer stated since the incident was reported chrysler refunded one month's payment and repaired/replaced the clock spring again on 10/17/07 or 10/19/07. And yet again on 11/02/07 the air bag light has since illuminated. The dealer stated rear hatch, passenger sliding door and fog lamp switch were inoperable. Updated 12/12/07 *tr
The check engine light has been going on and off randomly since the car was 3 months old. Purchased new. Told by a dealer in reno and a dealer in las vegas that it was nothing, they could not find a problem. Now after replacing the air conditioner condenser, and a new engine the whole body control module is going crazy. The whole panel goes on and off - ABS light, engine check light, air bag light, etc, the speedometer gauges etc--sometimes they work other times they shut down. This is dangerous not knowing your correct speed or if there is a problem with the automobile. Both automatic sliding doors quit a year ago and the lock on the passenger slider door quit working. *tr

How far this goes
This page is kept out of search results because 4 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 4 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 Dodge Caravan?
Across 3 owner reports that included an odometer reading, half were filed by 10,000 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 2007 Dodge Caravan?
4 reports have been filed with NHTSA, about 2.4 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.
