Other speed control problem on the 2005 Hyundai Elantra
4 crashes 1 injury 5 of the 12 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 2005 Hyundai Elantra report other speed control problem at a median of 30,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 55,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 60,000 miles at the ninetieth, a spread of 55,116 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.
60% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 3,084 miles | 7,212 miles | 27,710 miles | 52,500 miles | 58,200 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, 4 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 $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 2005 has 12. 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.
Traveling on the freeway the vehicle suddenly accelerated to 80mph and would not slow down it continued for about 15 miles before I put the veh in neutral and turned off the key,(the service dept at the dealer advised me to do that).at that time smoke poured out of the engine and I thought the veh was on fire. I called 911 . I was able to avoid a collision however the policeman asked me to move the car and when I turned on the key it started at full throttle I was afraid so I got out and refused to move the car. When a police officer moved the car it again started at full throttle. They towed it to the dealer, they said there is nothing wrong with it. I am afraid to drive it and I want a different veh or a refund.
2005 hyundai elantra. I have experienced intermittant wild acceleration when my foot is on the brake as if I had floored the accelerator. The dealer cannot duplicate the problem, thus no fix. *nm
I am having some what the same issue my husband had with his 2002 elantra which was reported to your organization, and had resulted in an accident. In my 2005 elantra the manufacturer evidently knew what the issue was in the 2002 and has now moved the brake pedal .75 of an inch to the left. This unfortunately only satisfied half of the problem. The brake pedal, when braking, still goes one inch below the accelerator thereby resulting in simultaneous braking and acceleration. If my husband had not discovered the problem, and installed corrective measures, I would have probably crashed. However, he had measured and corrected everything before I would take my first trip! I feel sorry for john doe as probably 99% of drivers would not realize what was the actual cause of their accident! I also cannot believe the government would not take action against hyundai to correct this issue in all of the elantra's so affected. You have to realize in most cases this is a blind issue as the driver will not be aware what the actual cause was. Recently a john doe filed a complaint listed on mycarstats.com whereby he continuously had the same issue…

How far this goes
Complaints are voluntary, so 12 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.

How common is other speed control problem on the 2005 Hyundai Elantra?

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.
