Other engine problem on the 2010 Hyundai Sonata
2 fires 2 of the 15 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 2010 Hyundai Sonata report other engine problem at a median of 65,000 miles. A quarter of the reports come in before 35,000 miles and a quarter after 90,000 miles, from 12 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 84,050 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.
33% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 24,750 miles | 32,846 miles | 63,000 miles | 88,250 miles | 108,800 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, 2 a fire is 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 26 model years of this car. It shows up earliest on the 2023, at a median of 100 miles, and latest on the 2008 at 115,000 miles.
By volume the 2011 carries the most reports, with 596; the 2010 has 15. 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.
I went out to start my car and it wouldn't start. I had to call a tow truck after a jump wouldn't work. I bought the car a year and a half ago and when the driver tested the battery, it wasn't dead but it wasn't great. I replaced the battery ($95 at walmart) and the car started. For a day. The next day the car wouldn't start again, when we realized it was then the starter. I purchased and installed a new starter on the vehicle ($105 online) issue resolved. Pretty young of a car for the starter to go. *tr
My 2010 hyundai sonata completely shut down on me 2-times in less than 5-minutes times while I was driving today. I was on my way to enter the expressway. The power steering and everything just shut down. My car just made a sudden stop. Thank god I had not entered the expressway and took the side streets home. I feel that this is a real safety hazard to myself, the passengers riding with me as well as other drivers, passengers and families on the road. My vehicle has 53,215 miles, there is no way this should be happening. If this is happening to my vehicle, I know it's occurring in other sonata's and other hyundai vehicles base on what I see in online entries on the 2010 hyundai sonata and hyundai vehicles. Manufactures must be held accountable for the defected products place on the market. I know that I'm a small voice against a large corporation, but if you take the time to investigate I know that my claim will be validated. I hope and pray that something is done about this before we are dealing with injuries or fatalities. I am a frustrated and unhappy hyundai sonata owner, looking for hyundai to put safety first! *tr

How far this goes

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.
