Other engine problem on the 2017 Hyundai Sonata
2 crashes 7 fires 9 of the 176 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 2017 Hyundai Sonata report other engine problem at a median of 67,500 miles. A quarter of the reports come in before 40,000 miles and a quarter after 107,500 miles, from 60 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 12,500 miles at the tenth percentile to 137,500 miles at the ninetieth, a spread of 125,400 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
23% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 11,900 miles | 39,250 miles | 68,500 miles | 107,021 miles | 137,300 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 crash and 7 a fire 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 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 2017 has 176. 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 I was driving I had come to a stop at the stop light. When it turned green I began to make a left turn. Halfway through the turn at a few miles an hour my engine light and traction control lights came on. At the same time the engine began to rev to about 4500 RPM. It died down quickly. I then had no response from the accelerator. Luckily I was able to pull over to the side of the road as I had just entered a town. I turned off the car and attempted to restart it. It would not restart until about 15 minutes later. The shifter became locked in the parking position and even after using the shift release button I was still unable to move the vehicle. Luckily again I had just entered a town but a few miles before that I was on country roads where there was no cell phone signal at all. I would have been out of luck as well as the passenger with me. After an hour and a half of waiting the tow vehicle came and was able to get it home and then once again towed to the dealership I had bought it from. It has now been sitting there for 5 days and have been told repeatedly now that no one understands what is wrong and have had to get a…
While driving to work this morning, brand new hyundai sonata with 980 miles shut down and turned itself off when I made a stop at a red light. I was lucky I wasn't moving fast on a highway when it happened and didn't get into an accident, but it's totally unacceptable for a brand new car to shut down like this.
Vehicle shut off at stop light. Engine, battery, and security lights illuminated on dash. Radio and AC continued to work. Vehicle started when start button was pressed and lights went off.

How far this goes
Complaints are voluntary, so 176 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.

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.
