Other speed control problem on the 2010 Hyundai Elantra
7 crashes 2 injuries 9 of the 14 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 other speed control problem gets reported
Owners of the 2010 Hyundai Elantra report other speed control problem at a median of 35,000 miles. A quarter of the reports come in before 30,000 miles and a quarter after 50,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 9th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 55,000 miles at the ninetieth, a spread of 50,754 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.
50% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 5,946 miles | 27,750 miles | 37,000 miles | 50,975 miles | 56,700 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, 7 a crash and 2 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 $250–$2,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 23 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 2009 at 85,000 miles.
By volume the 2013 carries the most reports, with 31; the 2010 has 14. 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.
While inching into my garage with my foot not on the gas, my 2010 hyundai elantra suddenly and unexpectedly accelerated and ran into my garages back wall before I could break. *kb
Tl* the contact owns a 2010 hyundai elantra. The contact stated that the vehicle abnormally accelerated with the brakes applied. The contact was unable to regain control of the vehicle and crashed into a port-a-potty. The contact was injured and a police report was filed of the incident. The vehicle was not repaired. The failure and the current mileage was 6,000.
This is not an isolated incident it is an ongoing problem with my vehicle. On my 2010 elantra automatic transmission, it is as though the gears are not working. When the car is in drive the issue arises. In order to get the car to 40 MPH I have to literally hit the gas and get the rpms to 5,000 or almost 6,000 before the car will shift. The car then shifts but when it is settling into 1000-2000 RPM's the power jerks as if it has lost power momentarily, this happens anytime you are trying to accelerate. Going up a small hill this car will go about 10-15 MPH for more than 30 seconds. This is unacceptable and could be a safety issue if the transmissions go out completely while these cars are being driven. Loosing the ability to shift should be a concern here. *tr

How far this goes
Complaints are voluntary, so 14 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 other speed control problem happen on the 2010 Hyundai Elantra?
Across 10 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 30,000 miles and a quarter after 50,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other speed control problem on the 2010 Hyundai Elantra?
14 reports have been filed with NHTSA, about 0.3 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.
