Control module (ECM/PCM/BCM) failure on the 2005 Hyundai Santa FE
1 crash 3 injuries 4 of the 6 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.
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 6 reports of control module (ECM/PCM/BCM) failure on the 2005 Hyundai Santa FE, 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 12th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 24,500 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 and 3 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 15 model years of this car. It shows up earliest on the 2023, at a median of 1,100 miles, and latest on the 2013 at 110,000 miles.
By volume the 2007 carries the most reports, with 26; the 2005 has 6. 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.
Passenger airbag system doesn't always work as per dash light, dealer can' t find anything wrong with system suggest turning off engine and restarting to reset computer. I tried this while driving in highway traffic and lost power to my brakes and steering , my wife weighs 135 pounds this should work the sensors. *jb
My 2005 santa fe (hyundai) was parked in my driveway. My 3 year old son got out of my sight for 2 seconds got into the car and put it in reverse and coasted out of my drive and across the street hitting my neighbors ford expedition. No keys and he is too small to reach any pedals. This was almost a devastating accident, there where children riding bikes on my street and a car driving down the street .it is almost a week now and I am getting nowhere with hyundai, and the dealer tells me they cannot do anything until hyundai inspects the car. Since the incident, I can still put the car in any gear without keys or touching pedals. And the steering wheel is locked so you cannot steer either. *tr
Both front and rear brakes have been repaired within last 6 or 7 months; however, front brakes pulsate (like ABS is engaging) when braking at low speeds for the past several months even before and after brake repairs. On dec 21, 2012, I dropped off my grandson at school and went to park on a street next to the school. The front brakes pulsated when braking to park (about 4 miles per hour) and then the brake pedal went all the way to the floor and I lost all braking power -- coasted to a stop (about 10 feet). I suspect the ABS control module is bad for some of the 2005 models. The 2003 and 2004 year model ABS control modules have been recalled but apparently not for the 2005 model years. *tr

How far this goes
This page is kept out of search results because 6 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 6 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 2005 Hyundai Santa FE?
Across 3 owner reports that included an odometer reading, half were filed by 25,000 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 2005 Hyundai Santa FE?
6 reports have been filed with NHTSA, about 0.1 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.
