Cruise control failure on the 2010 Hyundai Elantra
7 crashes 3 injuries 3 deaths 13 of the 11 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 cruise control failure gets reported
There are 11 reports of cruise control failure on the 2010 Hyundai Elantra, 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 72,000 miles. It is the 10th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 9,700 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, 3 an injury and 3 a fatality 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 $200–$1,400 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 13 model years of this car. It shows up earliest on the 2014, at a median of 1,500 miles, and latest on the 2021 at 110,000 miles.
By volume the 2021 carries the most reports, with 35; the 2010 has 11. 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.
When the cruise control was set between 40 and 50mph instead of being set at that speed/MPH the car kept accelerating to 70mph, only when I applied the brakes did it slow down. This happened 5 times in the past week, and I tested it out and it happens maybe 5% of the time but not in any random increment. *tr
Tl* the contact owns a 2010 hyundai elantra. While driving with the cruise control activated at approximately 65 MPH, the contact applied pressure to the brake pedal and pressed the off button for the cruise control to deactivate yet the cruise control would not deactivate. The contact stated that the vehicle crashed into a metal guardrail and the vehicle stopped fifty feet from the guard rail. The contact was uninjured and a police report was filed for the incident. The vehicle was towed to the dealer for body damage repairs. The manufacturer was contacted and a complaint was filed. The manufacturer was unable to provide further assistance but informed the contact that the vehicle was not equipped with a crash box. The approximate failure mileage was 9,700.
April 1st 2014 at aprox. 9:15am while performing an emergency acceleration in a 2010 hyundai elantra se with aprox.103000 miles car became stuck accelerating and continued to do once foot was lifted from both pedals. Brakes were effective at slowing vehicle but engine continued to accelerate at full throttle. Tapping accelerator was tried and was ineffective. Car was shifted by operator into neutral and red-lined on RPM. Operator slammed accelerator peddle to floor again and unintended acceleration stopped and car returned to normal function. No cruise control was being used, no hazard warning symbols came on. Car was shifted back to drive and no accident or injury occurred. Car accelerated to aprox 70mph under these conditions. Car was brought to a hyundai dealer for service a few hrs later who noted and showed customer how oem floor mats when properly installed can pop up and trap accelerator peddle down if accelerator peddle is forced to floor rapidly. Dealer was able to duplicate issue and removed floor mat from mounting on floor and left loose in driver's foot area. Customer put floor mat in back seat to avoid issues. *tr

How far this goes
This page is kept out of search results because 11 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 11 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 cruise control failure happen on the 2010 Hyundai Elantra?
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 cruise control failure on the 2010 Hyundai Elantra?
11 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.
