When other powertrain problem gets reported

Owners of the 2012 Kia Sorento report other powertrain problem at a median of 35,000 miles. A quarter of the reports come in before 10,000 miles and a quarter after 102,500 miles, from 35 reports that carried an odometer reading.

A part like this is normally expected to survive 92,000 miles. It is the 7th most-reported problem on this model year.

The mileage distribution

The reported range runs from 1,100 miles at the tenth percentile to 120,000 miles at the ninetieth, a spread of 119,490 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.

51% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 35 odometer readings owners gave.
10th25thMedian 75th90th
1,110 miles 9,172 miles 35,000 miles 103,327 miles 120,600 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 crash, 2 a fire and 2 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 $400–$4,500 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 22 model years of this car. It shows up earliest on the 2025, at a median of 200 miles, and latest on the 2005 at 95,000 miles.

By volume the 2011 carries the most reports, with 169; the 2012 has 45. 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 problem I am having is intermittent. When I push the start button sometimes the car the lunges backwards while the car is still in park it only does this when I am starting the car. It also makes an audible noise at the same time it is " buck jumping". I have taken it to the dealer several times an on the first visit they heard the noise and figured it was the starter. They put in a new starter and I am still having this problem. The transmission also seems to slip during city driving but it is very subtle. Now after about the fifth time being in the shop every time they say they can't reproduce my description of the problem to make a diagnosis so they can't fix it. However, they have already heard the problem because they put in a new starter and told me if the problem persists to bring it back. On one of the visits they rewired the electrical parts to see if it was an electrical problem and it was not. I am afraid that one of these days the car is actually going to move out of park and hit something. Every time I push the start button I hold my breath and go stiff because when it "acts" up the whole car jumps backwards as if…

100 miles NHTSA complaint 872677 filed 2011-08-09

I was starting off from stop sign and felt and heard a loud thud from the engine area. Immediately the 2012 sorento lost power and would not shift. It would continue to move at about 5 MPH. The engine did not stop. I stopped the vehicle and restarted but with the same symptoms. Being very close to the dealer, I took it in. The sales dept has agreed to find another vehicle and replace this one. I'm not so sure... *tr

125 miles NHTSA complaint 876493 filed 2011-08-29

2012 kia sorento v-6 AWD vehicle surges either forward or reverse during start up as if its partially in gear. Once started it seems to be fine and drives normally. The issue was sporadic at first but is now occuring on a daily basis. The dealership was first contacted on 8/27/11. The vehicle was then taken in on 9/6/11 but was not fixed as the dealership was having computer related issues. I have not been successful in getting a response from the dealer since then! 9/28/11

How far this goes

Complaints are voluntary, so 45 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 powertrain problem happen on the 2012 Kia Sorento?

Across 35 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 10,000 miles and a quarter after 102,500 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other powertrain problem on the 2012 Kia Sorento?

45 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.
