Other body or interior problem on the 2015 Hyundai Sonata
4 crashes 5 fires 3 injuries 12 of the 52 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 body or interior problem gets reported
Owners of the 2015 Hyundai Sonata report other body or interior problem at a median of 25,000 miles. A quarter of the reports come in before 15,000 miles and a quarter after 52,500 miles, from 33 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 7,500 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 71,760 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.
61% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 8,400 miles | 15,548 miles | 23,800 miles | 52,000 miles | 80,160 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, 5 a fire and 3 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 $200–$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.
The same failure on other years
The same failure is reported on 25 model years of this car. It shows up earliest on the 2023, at a median of 100 miles, and latest on the 2001 at 120,000 miles.
By volume the 2010 carries the most reports, with 147; the 2015 has 52. 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

We purchased a 2015 hyundai sonata sport/l1 on 26 dec 2014. My wife requires an extra cushion to sit on due lower back problems. Our previous car (2007 chevrolet impala) has sensors under the passenger seat that control the passenger air bag deployment. With my wife sitting on the extra cushion, the sensors correctly determined she was sitting in the passenger seat and set the airbag to operate if we were to be involved in an accident. Not realizing we were going to have a problem with the new hyundai sonata airbag sensors, we did not take the extra cushion along with us on the test drive. Three days later we discovered that the passenger airbag sensor did not recognize my wife sitting in the passenger seat while using her extra cushion for support. I brought this to the attention of the hyundai service department where I purchased the car. Several attempts to correct the problem were unsuccessful, and I finally convinced the general manager to have the ocs system connected to the diagnostic computer and check the operating specifications. The general manager and the service manager informed me that the sensors were working…
The primary purpose of filing this report is to prevent a child from dying in a locked trunk. As I packed my rental car for a trip I stupidly locked my keys in the trunk of the car. An unlocking service came and popped my door lock but because the alarm system was on there was absolutely no access to the truck at all. This model has drop down seats but are locked from in the trunk. It took a couple of hours for someone to correctly tell me to open the trunk I had to visit a hyundai dealership for a key....no other way to enter the trunk. I often drive across the desert...no dealership and no unlocking services. If my grandson had played in the trunk and locked himself in he would have died of heat exposure before it could have been unlocked. This is unnecessary. There are release levers in the trunk but a young child would be unable to pull them. This is a tragedy waiting to happen. I was saved only by the fact I was in a very large city. *tr

How far this goes
Complaints are voluntary, so 52 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 body or interior problem happen on the 2015 Hyundai Sonata?
Across 33 owner reports that included an odometer reading, half were filed by 25,000 miles. A quarter were filed before 15,000 miles and a quarter after 52,500 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other body or interior problem on the 2015 Hyundai Sonata?
52 reports have been filed with NHTSA, about 0.4 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.
