Other engine problem on the 2015 Kia Rio
5 fires 5 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 2015 Kia Rio report other engine problem at a median of 80,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 105,000 miles, from 8 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 10,000 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 101,895 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.
25% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 7,705 miles | 53,750 miles | 79,777 miles | 102,625 miles | 109,600 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, 5 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 17 model years of this car. It shows up earliest on the 2020, at a median of 300 miles, and latest on the 2018 at 110,000 miles.
By volume the 2001 carries the most reports, with 38; the 2015 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.
The engine periodically will stall for 2-3 seconds, usually when starting a left turn from a stop. This can prove hazardous in a busy intersection. This has been going on since I bought the car 12 october 2015. The dealer stated the "hesitation" was a normal function of the engine computer's "acclimation" to the driver. It hasn't adjusted to me, and I'm afraid to let my wife or daughter drive the car.
Purchased the car from kia dealer on 5/20/17 with limited power train warranty. Had oil change done on 7/22/17and again on 10/14/17(copies were provided to the warranty company). The second one was at the dealer. On 12/8/17 my daughter was driving down the street and felt a jolt and saw smoke coming from the hood of the car. She was able to pull over and get out of the car safely. Someone used a fire extinguisher to put out the fire before the fire department arrived. It was towed to a different kia dealership who said "the engine has internal damage that locked up the engine and caused oil to spill and catch fire." the warranty company denied the claim and said that it was lack of maintenance and there wasn't any oil in the car which contradicts what the dealer said. We tried fighting it but after a month we needed transportation and reported the claim to our insurance company who totaled the car but did not give us full value because the warranty company said it was lack of maintenance. Now we see all the reports on other kia's going on fire and believe our car had the same issue. We lost over $7,000 on the deal.

How far this goes
Complaints are voluntary, so 15 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 other engine problem happen on the 2015 Kia Rio?
Across 8 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before 55,000 miles and a quarter after 105,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other engine problem on the 2015 Kia Rio?
15 reports have been filed with NHTSA, about 0.5 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.
