Other engine problem on the 2012 Hyundai Accent
7 fires 1 injury 8 of the 25 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 engine problem gets reported
Owners of the 2012 Hyundai Accent report other engine problem at a median of 80,000 miles. A quarter of the reports come in before 60,000 miles and a quarter after 100,000 miles, from 18 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 15,000 miles at the tenth percentile to 115,000 miles at the ninetieth, a spread of 98,481 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
22% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 16,332 miles | 61,596 miles | 80,000 miles | 101,600 miles | 114,813 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 fire 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 $300–$4,000 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 18 model years of this car. It shows up earliest on the 2018, at a median of 200 miles, and latest on the 2016 at 100,000 miles.
By volume the 2012 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
Tl* the contact owns a 2012 hyundai accent. The contact stated that while driving approximately 60 to 65 MPH, the vehicle would suddenly decelerate. The vehicle was inspected by an authorized dealer, who stated that the fuel rail pressure sensor needed to be replaced. The vehicle was repaired. Approximately two days after having the vehicle repaired, the failure recurred. The vehicle was taken back to the dealer and was shipped to california for diagnosis. The failure mileage was approximately 202.
After pulling out from a stop vehicle would not accelerate and went to an idle mode, oil light and battery light illuminated but no check engine light. Vehicle was turned off and restarted and everything worked fine. Vehicle experienced the same problem about 20 minutes later. Vehicle was taken to hyundai dealership and the tech experienced the same problem during test drive. Vehicle did not store a dtc error code to dealership called tech line who advised to remove and clean throttle body. Vehicle was driven for 1 1/2 days following repair. Today while stopped at an intersection same problem occurred, oil light came on, battery light came on and vehicle went to idle mode. Vehicle was shut off and would not restart. Had to be towed to dealership. *tr
Around 50000 miles the car would over rev about 1000-2000 RPM when the clutch was released and foot off of the gas. It has progressively gotten worse. Now it will on its own while standing at idle run up to 5000-6000 RPM without warning and the only way to stop it is to turn the car off. When in gear, the car will accelerate without warning. If you depress the clutch, again it will run up to 5000-6000 RPM. The problem becomes exacerbated in warmer weather and lessened in cold weather. During the 12/24 heat wave here in pa, the car was undriveable and dangerous as I could not depend on it not "taking off". The dealer updated the software on 12/22 which did not resolve the issue, and no codes were found in the computer! Before 50,000 miles everything was fine.

How far this goes
Complaints are voluntary, so 25 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 engine problem on the 2012 Hyundai Accent?

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.
