Other engine problem on the 2006 Kia Sorento
2 crashes 3 fires 5 of the 45 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 2006 Kia Sorento report other engine problem at a median of 92,500 miles. A quarter of the reports come in before 65,000 miles and a quarter after 115,000 miles, from 42 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 50,000 miles at the tenth percentile to 137,500 miles at the ninetieth, a spread of 88,794 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.
2% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 48,756 miles | 65,000 miles | 92,996 miles | 114,000 miles | 137,550 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, 2 a crash and 3 a fire 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 $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 21 model years of this car. It shows up earliest on the 2023, at a median of 1,600 miles, and latest on the 2014 at 101,000 miles.
By volume the 2016 carries the most reports, with 340; the 2006 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 issue is with 2 kias I bought within the last year. Both automobiles had air conditioner compressors that failed within months of me purchasing it. The first kia I bought was a sedona 2003. The second is a sorento 2006 I bought november 2009. *tr
Crankshaft torque bolt sheared off causing the braking and steering to become stiff resulting in greatly diminished control of the vehicle. The pulley assembly began to squeal resulting in parking the vehicle until it was time to take it to the dealership for service of the concern. Enroute to the dealership the brake and engine light appeared and braking became sluggish and steering appeared to be stiff. Was able to make it to the dealership and I opened the hood seeing that the serpentine belt had come off. The following day the dealership notified me that the crankshaft torque bolt had sheared off and they were calling kia to determine a fix for replacing the bolt or if the engine would need replaced. After some brief research this appears to be a recurring problem for several kia models and model years. *tr

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 engine problem happen on the 2006 Kia Sorento?
Across 42 owner reports that included an odometer reading, half were filed by 92,500 miles. A quarter were filed before 65,000 miles and a quarter after 115,000 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 2006 Kia Sorento?
45 reports have been filed with NHTSA, about 2.6 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.
