Control module (ECM/PCM/BCM) failure on the 2010 Hyundai Santa FE
Only 6 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 2010 Hyundai Santa FE, 6 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 11th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 11,369 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 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 2010 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.

On saturday, jan. 15th, I was driving my 2010 hyundai santa fe v6 (4 1/2 months old, < 2000 miles) when I turned a corner onto a busy street, and the car lost all power as if someone had turned of the ignition. Luckily we were not in an accident when we lost power steering and engine power or when we sat in the middle of traffic since the car would not re-start. Roadside assistance was unable to send anyone for almost 40 minutes, so we had to have the police push us to safety. After being towed to the hyundai dealer for service, the car just started up again. We were told that they could not find the problem since no error code was seen. The technicians updated the ECM to version cman s2 ab8f since it was a recommended general service. No one knew if it would fix the problem. The technicians also mentioned that another customer had the same problem the week before. Hyundai consumer affairs was not helpful, but did open a case number. Problem has not re-occured yet although transmission often pops. *ln
The weekend we purchased our 2010 hyundai santa fe limited, v6, while driving in area with moderate grades vehicle had trouble shifting between 1st & 2nd gears, 2nd & 3rd gears. We thought it could be the area we were driving in, so we continued to drive it to see if that was it. It was not. Hard shifting has continued for the complete extent of our ownership commencing at the start. On 12/7/2010, took the vehicle in to be checked, cause: found transmission jerking. Module assy-auto trans control re, reset adaptive trans values. Recall, p0111, ECM update, performed camp tc7. Bring back if continues after a couple weeks. It did continue, but I am a busy person. On 4/21/2011, returned again stating that vehicle was continuing to shift hard, jerking. Dealer svc states could not duplicate. Vehicle duplicated for me on way home from svc appt. On 6/10/11, returned again for same problem with hard shifting at low speeds, jerking. Cause: tcm upgrade, re-reset adaptive trans values, after which svc dept said could not duplicate again. Svc mgr states that a new reflash had been issued since they upgraded it last on 12/7/2010. Thru research…
I have a 2010 santa fe with 19k miles.....twice this week I was driving and suddenly the gas pedal stopped working and engine light came on. Brakes worked, thank goodness. Anyone else have "sudden unintended deceleration"?? After the first event, I had it towed to the dealer (following protocol in the manual). They reported a new recall (it had been serviced a few months ago), executed a computer update and all was fixed (or so I thought). 4 days later, with less than 100 miles driven since the repair, it happened again. This time I was in 35mph traffic so when the accelerator pedal no longer worked, I almost was rear-ended. I was able to coast out of traffic (brakes and steering fine)to a side street. I was able to coast home (.5 mile or so). Car would accelerate after stop signs, although the gas pedal doesn't respond at all. Very scary that it even shifted to a higher gear and would go 30mph and keep accelerating if I didn't brake! The first repair info: 1. Spring protector install (tsb#11-01-021); cause: camp 2.tc7 cm ECM update p0111 10-01-034; cause: camp *tt

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 2010 Hyundai Santa FE?
Across 6 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 2010 Hyundai Santa FE?
6 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.
