Control module (ECM/PCM/BCM) failure on the 2000 Acura TL
2 crashes 1 injury 3 of the 13 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 2000 Acura TL report control module (ECM/PCM/BCM) failure at a median of 75,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 80,000 miles, from 9 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 45,000 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 36,400 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
11% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 45,000 miles | 54,930 miles | 74,800 miles | 80,000 miles | 81,400 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, 2 a crash and 1 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 $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 4 model years of this car. It shows up earliest on the 2012, at a median of 70,000 miles, and latest on the 2003 at 150,000 miles.
By volume the 2000 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
Srs system failure due to faulty part.*mr (nar) the consumer feels that the failure was due to a faulty part or design not wear or tear. The charges were unreasonably high due to poor design. An entire seat assembly should not have had to be replaced to fix an SRS sensor. *cb
Air bag light came on intermittently. Dealer serviced the vehicle. Then, consumer rear ended a vehicle at 50 MPH. A recall letter was later received by the consumer on the air bag module. Nhtsa recall 02v080000. *ak
Vehicle is a 2000 acura 3.2tl with 25,000 miles. Car "immobilizer" (anti-theft) system activated preventing car from starting. All keys locked out, so system itself at fault. There was no attempt to steal car (it was parked in garage at the time). If this had happened in a remote area, driver and passengers would have been stranded. Acura said that the only solution was to have car towed to dealership. I believe the anti-theft system is faulty and should be recalled for replacement or removal. *nm

How far this goes
Complaints are voluntary, so 13 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 2000 Acura TL?
Across 9 owner reports that included an odometer reading, half were filed by 75,000 miles. A quarter were filed before 55,000 miles and a quarter after 80,000 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 2000 Acura TL?
13 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.
