Wiring harness or short circuit on the 2012 Kia Sorento
3 fires 3 of the 13 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.
Only 7 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When wiring harness or short circuit gets reported
There are 13 reports of wiring harness or short circuit on the 2012 Kia Sorento, 7 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 88,000 miles. It is the 16th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 81,000 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, 3 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 $400–$3,500 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 10 model years of this car. It shows up earliest on the 2018, at a median of 10,000 miles, and latest on the 2011 at 150,000 miles.
By volume the 2011 carries the most reports, with 18; the 2012 has 13. 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.
Have to replace the bulb in my headlight. Used to be every 4-5 months. Now, it's 3 times in the last two weeks. After taking it to shop, wiring is shorting out, melting plastic around bulb and connection to car. Can not just replace little socket, like in most cars, kia wants you to replace the entire wiring harness, to the tune of over $500 for the part alone, not counting labor. After searching online, found thousands of complaints about the same issue for the last 9-10 years.
Issue #1: the lf headlight assembly on my vehicle even after being repaired and then replaced continues to stop working. In august 2017, my lf headlight started intermittently going out and by september 2017 failed permanently. I checked the light bulb which wasn't the issue and found that the connector to the bulb was burnt out with one of the prongs melted. I cut off the end and replaced it with a new socket (a h8/h11 headlight wiring harness socket - dorman# 84783). After replacing the socket, I drove my vehicle a couple days and lf headlight failed once again. First shutting off intermittently and then completely. I then took the vehicle to my local dealership, darcars lanham kia, 9020 lanham severn rd, lanham, md 20706. The dealership said the headlight assemble had a short and had to be replaced. I drove the vehicle home, ordered a new headlight, installed it and then drove my vehicle for a couple more days. Once again, the headlight started to fail intermittently, so I took the vehicle back to the dealership again. The new headlight failed completely while at the dealership. The dealership is now asking me to buy another…

How far this goes
This page is kept out of search results because 13 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 13 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 wiring harness or short circuit happen on the 2012 Kia Sorento?
Across 7 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is wiring harness or short circuit on the 2012 Kia Sorento?
13 reports have been filed with NHTSA, about 0.1 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.
