Other powertrain problem on the 2004 Kia Sorento

1 crash 1 injury 2 of the 16 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 powertrain problem gets reported

Owners of the 2004 Kia Sorento report other powertrain problem at a median of 70,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 105,000 miles, from 12 reports that carried an odometer reading.

A part like this is normally expected to survive 92,000 miles. It is the 3rd most-reported problem on this model year.

The mileage distribution

The reported range runs from 700 miles at the tenth percentile to 135,000 miles at the ninetieth, a spread of 135,661 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.

42% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 12 odometer readings owners gave.
10th25thMedian 75th90th
690 miles 4,125 miles 70,000 miles 106,750 miles 136,351 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, 1 a crash and 1 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 21 model years of this car. It shows up earliest on the 2019, at a median of 2,100 miles, and latest on the 2005 at 95,000 miles.

By volume the 2011 carries the most reports, with 169; the 2004 has 16. 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 consumer approached a driveway which had a slight incline. The consumer got out of the vehicle with the engine still running and the driver's door opened. At least two minutes later, a click was heard and the vehicle rolled backwards until it hit a tree. A kia representative came three days later, inspected the vehicle, and claimed no responsibility. *ak *sc *jb

1,500 miles NHTSA complaint 492088 filed 2004-08-23

Since buying my sorento in february 2004, I have noticed that the car sometimes has to "think" before going into gear and there is no predictability as to when this will happen. In example I was in the center lane merging into traffic when the car just would not get going it hesitates and then drops into gear. I have taken the car in and the service manager said that he has had several complaints like mine but there is nothing he could do to help. He said that it seems to be the combination of the engine and transmission and that since it seems to be just a characteristic of the car, there would be nothing that kia would do. I am concerned that this vehicle can cause an accident under normal driving conditions. Since it is a 6 cylinder, I would believe that it should get up and go when you need it. I always need to be aware that I cannot rely on the car to get in gear quickly. This is unsatisfactory, and I have never had a vehicle react in such a way.*ak

How far this goes

Complaints are voluntary, so 16 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 2004 Kia Sorento?

Across 12 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 5,000 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 powertrain problem on the 2004 Kia Sorento?

16 reports have been filed with NHTSA, about 0.6 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.
