What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 2,223 complaints with NHTSA about the 2003–2009 Kia Sorento, and 1,829 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
Failures are spread across the mileage range, with the middle half between 40,000 and 115,000 miles. The median is 79,400 miles.
The most-reported areas are the engine (11.9% of complaints, typically around 101,000 miles), the airbag system (11.7% of complaints, typically around 42,000 miles), the electrical system (10.2% of complaints, typically around 72,000 miles).
3 recall campaigns cover this generation.

Which systems, and when
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 79,400 miles; the figures below show which parts of the car run ahead of that and which run behind.
The engine accounts for 11.9% of complaints (265 reports, 240 of them with a mileage figure), with a median of 100,974 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 74,000 and 128,000 miles.
The airbag system accounts for 11.7% of complaints (259 reports, 190 of them with a mileage figure), and it fails early — a median of 42,500 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 5,500 and 97,000 miles.
The electrical system accounts for 10.2% of complaints (227 reports, 175 of them with a mileage figure), with a median of 72,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 113,000 miles.
The engine and its cooling system accounts for 9.5% of complaints (212 reports, 189 of them with a mileage figure), with a median of 66,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 47,500 and 82,779 miles.
The transmission and driveline accounts for 8.5% of complaints (190 reports, 166 of them with a mileage figure), with a median of 63,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 19,500 and 101,000 miles.
The exterior lighting accounts for 7.6% of complaints (168 reports, 119 of them with a mileage figure), with a median of 53,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 26,000 and 97,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2005 model year drew the most — 457 complaints — while 2009 drew the fewest at 79. The median year sits at 341.
Recalls and what they cover
NHTSA records 3 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Reported severity
Of the 2,223 complaints filed against this generation, 118 reported a crash; 68 reported a fire; 128 reported an injury; 6 reported a fatality. Crash-involved reports represent 5.3% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
What this means if you are buying one
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 40,000 and 115,000 miles, with a median of 79,400. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the engine and the airbag system are where this generation's reports concentrate, so those are the areas worth a specific look. The airbag system in particular shows a median failure mileage of 42,500, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
